- Pivotal trial found the enfortumab vedotin plus pembrolizumab combination significantly extended overall and progression-free survival vs platinum-containing chemotherapy- - If approved, enfortumab vedotin with KEYTRUDA would be the first combination in China to offer an alternative to chemotherapy, the current standard of care in first-line locally advanced or metastatic urothelial cancer- TOKYO, March 28, 2024 /PRNewswire/ -- Astellas Pharma Inc. (TSE:4503, President and CEO: Naoki Okamura, "Astellas") today announced that on March 27, 2024 the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has accepted the supplemental Biologics License Application (sBLA) for enfortumab vedotin with KEYTRUDA® (pembrolizumab) as a combination therapy for the first-line treatment of adult patients with previously untreated locally advanced or metastatic urothelial cancer (la/mUC). If approved, enfortumab vedotin with KEYTRUDA has the potential to change the treatment paradigm, becoming the first combination treatment to offer an alternative to platinum-containing chemotherapy, the current standard of care in first-line la/mUC. Urothelial cancer (UC) encompasses cancers of both the lower urinary tract (bladder and urethra) and upper tract (ureter and renal pelvis), with disease that originates in the lower tract accounting for 90% to 95% of all UC cases.i,ii Globally, approximately 614,000 new cases of bladder cancer and approximately 220,000 deaths are reported annually.iii It is estimated that approximately 93,000 people in China were diagnosed with bladder cancer and approximately 41,000 deaths were reported in 2022.iv Ahsan Arozullah, M.D., M.P.H., Senior Vice President, Head of Oncology Development, Astellas "Locally advanced or metastatic urothelial cancer is a life-threatening condition in China with nearly half of those diagnosed succumbing to the disease. The CDE's acceptance of our sBLA for enfortumab vedotin and pembrolizumab brings us one step closer to delivering a much-needed, innovative new treatment option for this patient population." Professor Guo Jun, lead PI in China for the EV-302 trial, director of the Department of Melanoma and Urological Oncology at Beijing Cancer Hospital, executive board member of the Chinese Society Of Clinical Oncology (CSCO) "In China, the recommended first-line treatment for advanced urothelial cancer is platinum-based chemotherapy, and there are currently no other treatments approved in the first-line setting. Given the efficacy brought by chemotherapy, alternate treatment options are extremely needed to extend survival benefits and potentially improve the prognosis of those patients. The results of the EV-302 study demonstrated that enfortumab vedotin in combination with pembrolizumab, as the first non-platinum first-line treatment, can achieve a clinically meaningful improvement in response rate, nearly double the median progression-free survival, and significantly improve the overall survival benefit of patients with locally advanced or metastatic urothelial cancer compared to chemotherapy." The sBLA for the first-line use of this combination is based on results from the Phase 3 EV-302 clinical trial (also known as KEYNOTE-A39). The study found that the combination improved overall survival (OS) and progression-free survival (PFS) with statistically significant and clinically meaningful results in patients with previously untreated la/mUC compared to platinum-containing chemotherapy. The safety results were consistent with those previously reported with this combination, and no new safety issues were identified. The NMPA is also reviewing enfortumab vedotin as a treatment for patients with locally advanced or metastatic urothelial cancer (la/mUC) who received prior treatment with a PD-1/L1 inhibitor and platinum-based chemotherapy. The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency is reviewing the enfortumab vedotin in combination with pembrolizumab therapy, as well as Japan's Ministry of Health, Labour and Welfare (MHLW). The U.S. Food and Drug Administration approved the combination therapy in December 2023. About EV-302 The EV-302 trial is an open-label, randomized, controlled Phase 3 study, evaluating enfortumab vedotin in combination with pembrolizumab versus platinum-containing chemotherapy in patients with previously untreated la/mUC. The study enrolled 886 patients with previously untreated la/mUC who were eligible for cisplatin- or carboplatin-containing chemotherapy regardless of PD-L1 status. Patients were randomized to receive either enfortumab vedotin in combination with pembrolizumab or platinum-containing chemotherapy. The dual primary endpoints of this trial are OS and PFS per RECIST v1.1 by blinded independent central review (BICR). Select secondary endpoints include ORR per RECIST v1.1 by BICR, DOR per RECIST v1.1 by BICR, and safety. The EV-302 trial is part of an extensive clinical program evaluating this combination in multiple stages of urothelial cancer and other solid tumors. Findings from EV-302 were presented at the European Society for Medical Oncology (ESMO) Congress 2023 in October 2023. About Bladder and Urothelial Cancer Urothelial cancer, or bladder cancer, begins in the urothelial cells, which line the urethra, bladder, ureters, renal pelvis, and some other organs.v If bladder cancer has spread to surrounding organs or muscles, it is called locally advanced disease. If the cancer has spread to other parts of the body, it is called metastatic disease.vi Urothelial cancer accounts for 90% of all bladder cancers and can also be found in the renal pelvis, ureter, and urethra.iii Approximately 12% of cases are locally advanced or metastatic urothelial cancer at diagnosis.vii Ongoing Investigational Trials The EV-302 trial (NCT04223856) is an open-label, randomized, controlled Phase 3 study, evaluating enfortumab vedotin in combination with pembrolizumab versus platinum-containing chemotherapy in patients with previously untreated locally advanced or metastatic urothelial cancer (la/mUC) who were eligible for cisplatin- or carboplatin-containing chemotherapy regardless of PD-L1 status. The EV-103 trial (NCT03288545) is an ongoing, multi-cohort, open-label, multicenter Phase 1b/2 study investigating enfortumab vedotin alone or in combination with pembrolizumab and/or chemotherapy in first- or second-line settings in patients with la/mUC and in patients with muscle-invasive bladder cancer (MIBC). Enfortumab vedotin in combination with pembrolizumab is being investigated in an extensive program in multiple stages of urothelial cancer, including two Phase 3 clinical trials in MIBC in EV-304 (NCT04700124, also known as KEYNOTE-B15) and EV-303 (NCT03924895, also known as KEYNOTE-905). The use of enfortumab vedotin in combination with pembrolizumab in second-line urothelial cancer and MIBC has not been proven safe or effective. The EV-202 trial (NCT04225117) is an ongoing, multi-cohort, open-label, multicenter Phase 2 study investigating enfortumab vedotin alone in patients with previously treated advanced solid tumors. This study also has a cohort that is investigating enfortumab vedotin in combination with pembrolizumab in patients with previously untreated recurrent/ metastatic head and neck squamous cell carcinoma. The EV-203 trial (NCT04995419) is a Phase 2, multicenter, single-arm bridging study in China designed to evaluate the efficacy, safety, and pharmacokinetic performance of enfortumab vedotin as treatment for patients in China. A total of 40 patients were enrolled in the study. About Enfortumab Vedotin Enfortumab vedotin is a first-in-class antibody-drug conjugate (ADC) that is directed against Nectin-4, a protein located on the surface of cells and highly expressed in bladder cancer.viii Nonclinical data suggest the anticancer activity of enfortumab vedotin is due to its binding to Nectin-4-expressing cells, followed by the internalization and release of the anti-tumor agent monomethyl auristatin E (MMAE) into the cell, which result in the cell not reproducing (cell cycle arrest) and in programmed cell death (apoptosis).ix PADCEV (enfortumab vedotin-ejfv) U.S. Indication & Important Safety Information BOXED WARNING: SERIOUS SKIN REACTIONS PADCEV can cause severe and fatal cutaneous adverse reactions including Stevens-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), which occurred predominantly during the first cycle of treatment, but may occur later. Closely monitor patients for skin reactions. Immediately withhold PADCEV and consider referral for specialized care for suspected SJS or TEN or severe skin reactions. Permanently discontinue PADCEV in patients with confirmed SJS or TEN; or Grade 4 or recurrent Grade 3 skin reactions. Indication PADCEV®, in combination with pembrolizumab, is indicated for the treatment of adult patients with locally advanced or metastatic urothelial cancer (mUC). PADCEV, as a single agent, is indicated for the treatment of adult patients with locally advanced or mUC who: have previously received a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor and platinum-containing chemotherapy, or are ineligible for cisplatin-containing chemotherapy and have previously received one or more prior lines of therapy. IMPORTANT SAFETY INFORMATION Warnings and Precautions Skin reactions Severe cutaneous adverse reactions, including fatal cases of SJS or TEN occurred in patients treated with PADCEV. SJS and TEN occurred predominantly during the first cycle of treatment but may occur later. Skin reactions occurred in 70% (all grades) of the 564 patients treated with PADCEV in combination with pembrolizumab in clinical trials. When PADCEV was given in combination with pembrolizumab, the incidence of skin reactions, including severe events, occurred at a higher rate compared to PADCEV as a single agent. The majority of the skin reactions that occurred with combination therapy included maculo-papular rash, macular rash and papular rash. Grade 3-4 skin reactions occurred in 17% of patients (Grade 3: 16%, Grade 4: 1%), including maculo-papular rash, bullous dermatitis, dermatitis, exfoliative dermatitis, pemphigoid, rash, erythematous rash, macular rash, and papular rash. A fatal reaction of bullous dermatitis occurred in one patient (0.2%). The median time to onset of severe skin reactions was 1.7 months (range: 0.1 to 17.2 months). Skin reactions led to discontinuation of PADCEV in 6% of patients. Skin reactions occurred in 58% (all grades) of the 720 patients treated with PADCEV as a single agent in clinical trials. Twenty-three percent (23%) of patients had maculo-papular rash and 34% had pruritus. Grade 3-4 skin reactions occurred in 14% of patients, including maculo-papular rash, erythematous rash, rash or drug eruption, symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), bullous dermatitis, exfoliative dermatitis, and palmar-plantar erythrodysesthesia. The median time to onset of severe skin reactions was 0.6 months (range: 0.1 to 8 months). Among patients experiencing a skin reaction leading to dose interruption who then restarted PADCEV (n=75), 24% of patients restarting at the same dose and 24% of patients restarting at a reduced dose experienced recurrent severe skin reactions. Skin reactions led to discontinuation of PADCEV in 3.1% of patients. Monitor patients closely throughout treatment for skin reactions. Consider topical corticosteroids and antihistamines, as clinically indicated. For persistent or recurrent Grade 2 skin reactions, consider withholding PADCEV until Grade ≤1. Withhold PADCEV and refer for specialized care for suspected SJS, TEN or for Grade 3 skin reactions. Permanently discontinue PADCEV in patients with confirmed SJS or TEN; or Grade 4 or recurrent Grade 3 skin reactions. Hyperglycemia and diabetic ketoacidosis (DKA), including fatal events, occurred in patients with and without pre-existing diabetes mellitus, treated with PADCEV. Patients with baseline hemoglobin A1C ≥8% were excluded from clinical trials. In clinical trials of PADCEV as a single agent, 17% of the 720 patients treated with PADCEV developed hyperglycemia of any grade; 7% of patients developed Grade 3-4 hyperglycemia (Grade 3: 6.5%, Grade 4: 0.6%). Fatal events of hyperglycemia and DKA occurred in one patient each (0.1%). The incidence of Grade 3-4 hyperglycemia increased consistently in patients with higher body mass index and in patients with higher baseline A1C. The median time to onset of hyperglycemia was 0.5 months (range: 0 to 20 months). Hyperglycemia led to discontinuation of PADCEV in 0.7% of patients. Five percent (5%) of patients required initiation of insulin therapy for treatment of hyperglycemia. Of the patients who initiated insulin therapy for treatment of hyperglycemia, 66% (23/35) discontinued insulin at the time of last evaluation. Closely monitor blood glucose levels in patients with, or at risk for, diabetes mellitus or hyperglycemia. If blood glucose is elevated (>250 mg/dL), withhold PADCEV. Pneumonitis/Interstitial Lung Disease (ILD) Severe, life-threatening or fatal pneumonitis/ILD occurred in patients treated with PADCEV. When PADCEV was given in combination with pembrolizumab, 10% of the 564 patients treated with combination therapy had pneumonitis/ILD of any grade and 4% had Grade 3-4. A fatal event of pneumonitis/ILD occurred in two patients (0.4%). The incidence of pneumonitis/ILD, including severe events, occurred at a higher rate when PADCEV was given in combination with pembrolizumab compared to PADCEV as a single agent. The median time to onset of any grade pneumonitis/ILD was 4 months (range: 0.3 to 26 months). In clinical trials of PADCEV as a single agent, 3% of the 720 patients treated with PADCEV had pneumonitis/ILD of any grade and 0.8% had Grade 3-4. The median time to onset of any grade pneumonitis/ILD was 2.9 months (range: 0.6 to 6 months). Monitor patients for signs and symptoms indicative of pneumonitis/ILD such as hypoxia, cough, dyspnea or interstitial infiltrates on radiologic exams. Evaluate and exclude infectious, neoplastic and other causes for such signs and symptoms through appropriate investigations. Withhold PADCEV for patients who develop Grade 2 pneumonitis/ILD and consider dose reduction. Permanently discontinue PADCEV in all patients with Grade 3 or 4 pneumonitis/ILD. Peripheral neuropathy (PN) When PADCEV was given in combination with pembrolizumab, 67% of the 564 patients treated with combination therapy had PN of any grade, 36% had Grade 2 neuropathy, and 7% had Grade 3 neuropathy. The incidence of PN occurred at a higher rate when PADCEV was given in combination with pembrolizumab compared to PADCEV as a single agent. The median time to onset of Grade ≥2 PN was 6 months (range: 0.3 to 25 months). PN occurred in 53% of the 720 patients treated with PADCEV as a single agent in clinical trials including 38% with sensory neuropathy, 8% with muscular weakness and 7% with motor neuropathy. Thirty percent of patients experienced Grade 2 reactions and 5% experienced Grade 3-4 reactions. PN occurred in patients treated with PADCEV with or without preexisting PN. The median time to onset of Grade ≥2 PN was 4.9 months (range: 0.1 to 20 months). Neuropathy led to treatment discontinuation in 6% of patients. Monitor patients for symptoms of new or worsening PN and consider dose interruption or dose reduction of PADCEV when PN occurs. Permanently discontinue PADCEV in patients who develop Grade ≥3 PN. Ocular disorders were reported in 40% of the 384 patients treated with PADCEV as a single agent in clinical trials in which ophthalmologic exams were scheduled. The majority of these events involved the cornea and included events associated with dry eye such as keratitis, blurred vision, increased lacrimation, conjunctivitis, limbal stem cell deficiency, and keratopathy. Dry eye symptoms occurred in 30% of patients, and blurred vision occurred in 10% of patients, during treatment with PADCEV. The median time to onset to symptomatic ocular disorder was 1.7 months (range: 0 to 30.6 months). Monitor patients for ocular disorders. Consider artificial tears for prophylaxis of dry eyes and ophthalmologic evaluation if ocular symptoms occur or do not resolve. Consider treatment with ophthalmic topical steroids, if indicated after an ophthalmic exam. Consider dose interruption or dose reduction of PADCEV for symptomatic ocular disorders. Infusion site extravasation Skin and soft tissue reactions secondary to extravasation have been observed after administration of PADCEV. Of the 720 patients treated with PADCEV as a single agent in clinical trials, 1% of patients experienced skin and soft tissue reactions, including 0.3% who experienced Grade 3-4 reactions. Reactions may be delayed. Erythema, swelling, increased temperature, and pain worsened until 2-7 days after extravasation and resolved within 1-4 weeks of peak. Two patients (0.3%) developed extravasation reactions with secondary cellulitis, bullae, or exfoliation. Ensure adequate venous access prior to starting PADCEV and monitor for possible extravasation during administration. If extravasation occurs, stop the infusion and monitor for adverse reactions. Embryo-fetal toxicity PADCEV can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during PADCEV treatment and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with PADCEV and for 4 months after the last dose.

Efficacy and Safety Pro Once-Daily Vemlidy Demonstrated in Children Six Years of Age (Weighing at Least 25kg) and Older FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the U.S. Food and Drug Administration (FDA) has approved the supplemental new drug application (sNDA) for Vemlidy® (tenofovir alafenamide) 25 mg tablets as a once-daily treatment for chronic hepatitis B virus (HBV) infection in pediatric patients six years of age and older and weighing at least 25 kg with compensated liver disease. Vemlidy is a targeted prodrug of tenofovir that was approved by the FDA in 2016 as a once-daily treatment for adults with chronic HBV infection with compensated liver disease. In 2022, the FDA approved Vemlidy for the treatment of chronic HBV infection in pediatric patients 12 years of age and older with compensated liver disease. Vemlidy is recommended as a preferred or first-line treatment for adults with chronic HBV with compensated liver disease by the American Association for the Study of Liver Diseases (AASLD) and European Association for the Study of the Liver (EASL) guidelines. “Chronic hepatitis B can have a significant and lasting impact on the health of children. If left untreated, hepatitis B can lead to liver cirrhosis and liver cancer,” said Chaun-Hao Lin, MD, Associate Professor of Clinical Pediatrics Krek School of Medicine of USC. “As a clinician, I am well aware of the critical importance of promptly treating this disease to avoid possible complications and liver damage. The clinical trial demonstrated that tenofovir alafenamide may represent an effective treatment option for children as young as six years old affected by this chronic disease.” Vemlidy’s approval in this pediatric patient population is supported by Week 96 data from a Phase 2 clinical trial (Trial 1092) comparing treatment with Vemlidy 25 mg to placebo among 18 treatment-naïve and treatment-experienced patients aged 6 to less than 12 years weighing at least 25 kg (Cohort 2, Group 1). Participants in the Vemlidy group and in the placebo group who switched to open-label Vemlidy after Week 24 demonstrated progressive increases in the rates of virological suppression through Week 96 overall and within both study cohorts (children and adolescents). “The expanded indication for Vemlidy for the treatment of children as young as six years old is a testament to the safety, tolerability and efficacy pro this therapy,” said Frank Duff, MD, Senior Vice President, Virology Therapeutic Area Head, Gilead Sciences. “Effective and tolerable options for children require our best science and a dedicated focus. The work of our Gilead Pediatric Center of Excellence is responsible for coordinating pediatric clinical trials for treatments for cancer, HIV, hepatitis B, and COVID-19 and we will continue our research to help address unmet treatment needs for children.” Vemlidy has a boxed warning in its product label regarding post-treatment severe acute exacerbation of hepatitis B. See below for important safety information. U.S. IMPORTANT SAFETY INFORMATION AND INDICATION FOR THE USE OF VEMLIDY BOXED WARNING: POSTTREATMENT SEVERE ACUTE EXACERBATION OF HEPATITIS B Discontinuation of anti-hepatitis B therapy, including VEMLIDY, may result in severe acute exacerbations of hepatitis B. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy, including VEMLIDY. If appropriate, resumption of anti-hepatitis B therapy may be warranted. Warnings and Precautions Risk of Development of HIV-1 Resistance in HBV/HIV-1 Coinfected Patients: Due to this risk, VEMLIDY alone should not be used for the treatment of HIV-1 infection. Safety and efficacy of VEMLIDY have not been established in HBV/HIV-1 coinfected patients. HIV antibody testing should be offered to all HBV-infected patients before initiating therapy with VEMLIDY, and if positive, an appropriate antiretroviral combination regimen that is recommended for HBV/HIV-1 coinfected patients should be used. New Onset or Worsening Renal Impairment: Postmarketing cases of renal impairment, including acute renal failure, proximal renal tubulopathy (PRT), and Fanconi syndrome, have been reported with TAF-containing products. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue VEMLIDY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Monitor renal function in all patients – See Dosage and Administration. Lactic Acidosis and Severe Hepatomegaly with Steatosis: Fatal cases have been reported with the use of nucleoside analogs, including tenofovir disoproxil fumarate (TDF). Discontinue VEMLIDY if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity develop, including hepatomegaly and steatosis in the absence of marked transaminase elevations. Adverse Reactions Most common adverse events in the week 96 pediatric population reported in ≥5% were: nasopharyngitis, headache, COVID-19, pyrexia, diarrhea, upper respiratory tract infection, cough, respiratory tract infection viral, abdominal pain upper. Overall, abdominal pain upper and metabolic nephropathy were the only study drug–related adverse events, which occurred in > 1 participant, reported in 2.3% (2/88 participants) each. Drug Interactions Coadministration of VEMLIDY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of tenofovir and the risk of adverse reactions. Coadministration of VEMLIDY is not recommended with the following: oxcarbazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, or St. John’s wort. Such coadministration is expected to decrease the concentration of tenofovir alafenamide, reducing the therapeutic effect of VEMLIDY. Drugs that strongly affect P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) activity may lead to changes in VEMLIDY absorption. Coadministration of VEMLIDY with carbamazepine, the tenofovir alafenamide dose should be increased to two tablets once daily. Consult the full prescribing information for VEMLIDY for more information on potentially significant drug interactions, including clinical comments. Dosage and Administration Testing Prior to Initiation: HIV infection. Prior to or When Initiating, and During Treatment: On a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. Dosage: 1 tablet taken once daily with food. Renal Impairment: Not recommended in patients with end-stage renal disease (ESRD; eCrCl <15 mL/min) who are not receiving chronic hemodialysis; in patients on chronic hemodialysis, on hemodialysis days, administer VEMLIDY after completion of hemodialysis treatment. No data are available to make dose recommendations in pediatric patients with renal impairment. Hepatic Impairment: Not recommended in patients with decompensated (Child-Pugh B or C) hepatic impairment. Indication VEMLIDY is indicated for the treatment of chronic hepatitis B virus infection in adults and pediatric patients six years of age and older and weighing at least 25 kg with compensated liver disease. About the 1092 Study Study 1092 is an ongoing Phase 2 clinical trial that randomized 88 treatment-naïve and treatment-experienced patients with chronic hepatitis B infection between the ages of 12 to less than 18 years weighing at least 35 kg to receive either Vemlidy 25 mg (N=47) or placebo (N=23) and 6 to less than 12 years weighing at least 25 kg to receive either Vemlidy 25 mg (N = 12) or placebo (N=6) once daily. The study met its primary endpoint of percentage of patients with HBV DNA levels below 20 IU/mL at 24 weeks of therapy; overall, 19% (11/59) of patients treated with Vemlidy 25 mg achieved HBV DNA < 20 IU/mL at Week 24 compared to 0% (0/23) of patients treated with placebo. The overall percentage of patients with HBV DNA < 20 IU/mL progressively increased in the Vemlidy 25 mg group relative to the Week 24 time point at both Week 48 (37% [22/59 subjects]) and Week 96 (61.0% [36/59 subjects]). The overall median change from baseline in ALT values for the Vemlidy and placebo-Vemlidy treatment groups, respectively, was -39.5 U/L and -46.5 U/L at Week 96. At 96 weeks, ALT normalization (AASLD criteria) was achieved for 54% of Vemlidy-treated patients and 57% of patients who switched from placebo to Vemlidy. Serum ALT is an enzyme used to monitor liver damage. Importantly, the mean percent changes in bone mineral density from baseline to Week 24 were similar for Vemlidy-treated patients and placebo-treated patients (1.6% (N=48) and 1.9% (N=23) for lumbar spine, and 1.9% (N=50) and 2.0% (N=23) for whole body, respectively). At Week 24, mean changes from baseline BMD Z-scores were 0.01 and -0.07 for the lumbar spine, and -0.04 and -0.04 for whole body, for Vemlidy and placebo groups, respectively. About Hepatitis B Hepatitis B (HBV) is a serious disease that attacks the liver and can cause chronic (lifelong) infection, cirrhosis of the liver, liver cancer, and death in up to a third of patients. Hepatitis B is spread through infected blood or body fluids, sexual contact, injection drug use, or perinatally from mother to child. Early symptoms may include loss of appetite, fever, generalized aches and pains, fatigue, itching, urticaria (hives), and joint pain. The disease is often asymptomatic, which may lead to undiagnosed individuals. Later symptoms may include nausea and vomiting, halitosis (bad breath), dark brown urine, jaundice (yellowing of the skin and eyes), and right-sided abdominal pain (especially with external pressure or palpitation).

Analysis from a 10-month post-launch evaluation of the REMS Program finds 2.8% incidence of LVEF <50% in over 1500 patients, strengthening the safety pro CAMZYOS® (mavacamten) for NYHA class II-III obstructive hypertrophic cardiomyopathy Real-world data reaffirm therapeutic value and treatment benefit of CAMZYOS in improving cardiac symptoms and NYHA class in patients with obstructive hypertrophic cardiomyopathy PRINCETON, N.J.--(BUSINESS WIRE)-- Bristol Myers Squibb Company (NYSE: BMY) today announced the presentation of data at the American College of Cardiology (ACC) Annual Scientific Session & Expo, taking place April 6-8, 2024 in Atlanta, Georgia. “The therapeutic benefit of CAMZYOS in real-world practice, demonstrated by our data at ACC, builds on the well-established clinical program and further underscores the importance of this transformational medicine which is the first and only approved cardiac myosin inhibitor. With thousands of patients around the world treated to date, CAMZYOS is redefining the treatment landscape for this patient population and may offer hope to countless others moving forward,” said Roland Chen, MD, Senior Vice President and Head of Development, Immunology, Cardiovascular & Neurology. “In addition to showcasing our growing body of real-world evidence and safety data for CAMZYOS at ACC, we look forward to highlighting additional data from our cardiovascular portfolio, including an analysis of the real-world clinical impact of ELIQUIS.” Research to be presented at the meeting supports the robust safety and clinical pro CAMZYOS® (mavacamten) and compliance with the Risk Evaluation and Mitigation Strategy (REMS) Program. These data include: An analysis of results from the 10-month post-launch evaluation of the CAMZYOS REMS Program in 1,524 patients with patient status forms submitted, which demonstrated that approximately 1% (n=17) of patients reported clinical heart failure requiring hospitalization and 2.8% (n=43) of patients reported a decrease in left ventricular ejection fraction (LVEF) to <50%. These data are consistent with the clinical development program and reinforce the safety pro CAMZYOS in clinical practice. These data (abstract 1075-07) will be featured as a moderated poster on Sunday, April 7 from 1:30 PM – 1:40 PM ET. A single-center real-world experience analysis of 53 patients treated with CAMZYOS which found that at 24 weeks, CAMZYOS led to improvements in cardiovascular symptoms (96%) and improvements in one or more New York Heart Association (NYHA) class (49%). Additionally, resting and Valsalva LVOT gradient decreased during the first four weeks after starting treatment, with statistically significant reductions from baseline at week 24 (P<0.001). No patients required cessation of treatment due to reduction of LVEF to <50% or other side effects, though two patients required temporary drug discontinuation due to Valsalva LVOT gradient less than 20 mmHg during the 24-week treatment period. These data (abstract 1424-134) will be featured as a poster on Sunday, April 7 from 1:15 PM – 2:00 PM ET. The BMS-Pfizer Alliance will also present research at the meeting that adds to the robust body of evidence pertaining to the safety and efficacy pro ELIQUIS® (apixaban). These data include: A real-world evidence study of non-valvular atrial fibrillation (NVAF) patients on Medicare previously treated with warfarin and switched to a direct oral anticoagulant (DOAC: apixaban, dabigatran, or rivaroxaban), which found that those who received ELIQUIS had a statistically significant lower risk of stroke/systemic embolism (S/SE) and major bleeding (MB) than those patients who received rivaroxaban (S/SE HR: 0.91; 95% CI: 0.85-0.97 and MB HR: 0.68; 95% CI: 0.65-0.72) or dabigatran (S/SE HR: 0.83; 95% CI: 0.72-0.96 and MB HR: 0.79; 95% CI: 0.71-0.89). This pairwise comparative analysis provides the rates of S/SE and MB shown in patients with NVAF on Medicare associated with switching from warfarin to different DOACs. This effectiveness and safety information about ELIQUIS use in clinical practice can supplement data from randomized clinical trials. These data (abstract 1306-157) will be featured as a poster on Saturday, April 6 from 2:45 PM – 3:00 PM ET.

Poster – 1075-09 1075 - Bulking Up: Advances in Hypertrophic Cardiomyopathy 1:45 PM – 1:55 PM *Sponsored by the Bristol Myers Squibb-Pfizer Alliance About CAMZYOS® (mavacamten) CAMZYOS® (mavacamten) is the first and only cardiac myosin inhibitor approved in the U.S., indicated for the treatment of adults with symptomatic New York Heart Association (NYHA) class II-III obstructive hypertrophic cardiomyopathy (HCM) to improve functional capacity and symptoms, and in the European Union, indicated for the treatment of symptomatic (NYHA, class II-III) obstructive HCM in adult patients. It has also received regulatory approvals on five continents including in Argentina, Australia, Brazil, Canada, Great Britain, Hong Kong, Israel, Singapore, South Korea, and Switzerland. CAMZYOS is an allosteric and reversible inhibitor selective for cardiac myosin. CAMZYOS modulates the number of myosin heads that can enter “on actin” (power-generating) states, thus reducing the probability of force-producing (systolic) and residual (diastolic) cross-bridge formation. Excess myosin actin cross-bridge formation and dysregulation of the super-relaxed state are mechanistic hallmarks of HCM. CAMZYOS shifts the overall myosin population towards an energy-sparing, recruitable, super-relaxed state. In HCM patients, myosin inhibition with CAMZYOS reduces dynamic left ventricular outflow tract (LVOT) obstruction and improves cardiac filling pressures. IMPORTANT SAFETY INFORMATION WARNING: RISK OF HEART FAILURE CAMZYOS reduces left ventricular ejection fraction (LVEF) and can cause heart failure due to systolic dysfunction. Echocardiogram assessments of LVEF are required prior to and during treatment with CAMZYOS. Initiation of CAMZYOS in patients with LVEF <55% is not recommended. Interrupt CAMZYOS if LVEF is <50% at any visit or if the patient experiences heart failure symptoms or worsening clinical status. Concomitant use of CAMZYOS with certain cytochrome P450 inhibitors or discontinuation of certain cytochrome P450 inducers may increase the risk of heart failure due to systolic dysfunction; therefore, the use of CAMZYOS is contraindicated with the following: Moderate to strong CYP2C19 inhibitors or strong CYP3A4 inhibitors Moderate to strong CYP2C19 inducers or moderate to strong CYP3A4 inducers Because of the risk of heart failure due to systolic dysfunction, CAMZYOS is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the CAMZYOS REMS PROGRAM. CONTRAINDICATIONS CAMZYOS is contraindicated with concomitant use of: Moderate to strong CYP2C19 inhibitors or strong CYP3A4 inhibitors Moderate to strong CYP2C19 inducers or moderate to strong CYP3A4 inducers WARNINGS AND PRECAUTIONS Heart Failure CAMZYOS reduces systolic contraction and can cause heart failure or totally block ventricular function. Patients who experience a serious intercurrent illness (e.g., serious infection) or arrhythmia (e.g., atrial fibrillation or other uncontrolled tachyarrhythmia) are at greater risk of developing systolic dysfunction and heart failure. Assess the patient’s clinical status and LVEF prior to and regularly during treatment and adjust the CAMZYOS dose accordingly. New or worsening arrhythmia, dyspnea, chest pain, fatigue, palpitations, leg edema, or elevations in N-terminal pro-B-type natriuretic peptide (NT-proBNP) may be signs and symptoms of heart failure and should also prompt an evaluation of cardiac function. Asymptomatic LVEF reduction, intercurrent illnesses, and arrhythmias require additional dosing considerations. Initiation of CAMZYOS in patients with LVEF <55% is not recommended. Avoid concomitant use of CAMZYOS in patients on disopyramide, ranolazine, verapamil with a beta blocker, or diltiazem with a beta blocker as these medications and combinations increase the risk of left ventricular systolic dysfunction and heart failure symptoms and clinical experience is limited. CYP 450 Drug Interactions Leading to Heart Failure or Loss of Effectiveness CAMZYOS is primarily metabolized by CYP2C19 and CYP3A4 enzymes. Concomitant use of CAMZYOS and drugs that interact with these enzymes may lead to life-threatening drug interactions such as heart failure or loss of effectiveness. Advise patients of the potential for drug interactions, including with over-the-counter medications (such as omeprazole, esomeprazole, or cimetidine). Advise patients to inform their healthcare provider of all concomitant products prior to and during CAMZYOS treatment. CAMZYOS Risk Evaluation and Mitigation Strategy (REMS) Program CAMZYOS is only available through a restricted program called the CAMZYOS REMS Program because of the risk of heart failure due to systolic dysfunction. Notable requirements of the CAMZYOS REMS Program include the following: Prescribers must be certified by enrolling in the REMS Program. Patients must enroll in the REMS Program and comply with ongoing monitoring requirements. Pharmacies must be certified by enrolling in the REMS Program and must only dispense to patients who are authorized to receive CAMZYOS. Wholesalers and distributors must only distribute to certified pharmacies. Further information is available at or by telephone at 1-833-628-7367. Embryo-Fetal Toxicity CAMZYOS may cause fetal toxicity when administered to a pregnant female, based on animal studies. Confirm absence of pregnancy in females of reproductive potential prior to treatment and advise patients to use effective contraception during treatment with CAMZYOS and for 4 months after the last dose. CAMZYOS may reduce the effectiveness of combined hormonal contraceptives (CHCs). Advise patients using CHCs to use an alternative contraceptive method that is not affected by CYP 450 enzyme induction or to add nonhormonal contraception. Advise females of reproductive potential about the potential risk to the fetus with maternal exposure to CAMZYOS during pregnancy. ADVERSE REACTIONS In the EXPLORER-HCM trial, adverse reactions occurring in >5% of patients and more commonly in the CAMZYOS group than in the placebo group were dizziness (27% vs 18%) and syncope (6% vs 2%). There were no new adverse reactions identified in VALOR-HCM. Effects on Systolic Function In the EXPLORER-HCM trial, mean (SD) resting LVEF was 74% (6) at baseline in both treatment groups. Mean (SD) absolute change from baseline in LVEF was -4% (8) in the CAMZYOS group and 0% (7) in the placebo group over the 30-week treatment period. At Week 38, following an 8-week interruption of trial drug, mean LVEF was similar to baseline for both treatment groups. In the EXPLORER-HCM trial, 7 (6%) patients in the CAMZYOS group and 2 (2%) patients in the placebo group experienced reversible reductions in LVEF <50% (median 48%: range 35-49%) while on treatment. In all 7 patients treated with CAMZYOS, LVEF recovered following interruption of CAMZYOS. DRUG INTERACTIONS Potential for Other Drugs to Affect Plasma Concentrations of CAMZYOS CAMZYOS is primarily metabolized by CYP2C19 and to a lesser extent by CYP3A4 and CYP2C9. Inducers and inhibitors of CYP2C19 and moderate to strong inhibitors or inducers of CYP3A4 may affect the exposures of CAMZYOS. Impact of Other Drugs on CAMZYOS: Moderate to Strong CYP2C19 Inhibitors or Strong CYP3A4 Inhibitors: Concomitant use increases CAMZYOS exposure, which may increase the risk of heart failure due to systolic dysfunction. Concomitant use is contraindicated. Moderate to Strong CYP2C19 Inducers or Moderate to Strong CYP3A4 Inducers: Concomitant use decreases CAMZYOS exposure, which may reduce CAMZYOS’ efficacy. The risk of heart failure due to systolic dysfunction may increase with discontinuation of these inducers as the levels of induced enzyme normalizes. Concomitant use is contraindicated. Weak CYP2C19 Inhibitors or Moderate CYP3A4 Inhibitors: Concomitant use with a weak CYP2C19 inhibitor or a moderate CYP3A4 inhibitor increases CAMZYOS exposure, which may increase the risk of adverse drug reactions. Initiate CAMZYOS at the recommended starting dose of 5 mg orally once daily in patients who are on stable therapy with a weak CYP2C19 inhibitor or a moderate CYP3A4 inhibitor. Reduce dose of CAMZYOS by one level (i.e., 15 to 10 mg, 10 to 5 mg, or 5 to 2.5 mg) in patients who are on CAMZYOS treatment and intend to initiate a weak CYP2C19 inhibitor or a moderate CYP3A4 inhibitor. Schedule clinical and echocardiographic assessment 4 weeks after inhibitor initiation, and do not up-titrate CAMZYOS until 12 weeks after inhibitor initiation. Avoid initiation of concomitant weak CYP2C19 and moderate CYP3A4 inhibitors in patients who are on stable treatment with 2.5 mg of CAMZYOS because a lower dose is not available. Potential for CAMZYOS to Affect Plasma Concentrations of Other Drugs CAMZYOS is an inducer of CYP3A4, CYP2C9, and CYP2C19. Concomitant use with CYP3A4, CYP2C19, or CYP2C9 substrates may reduce plasma concentration of these drugs. Closely monitor when CAMZYOS is used in combination with CYP3A4, CYP2C19, or CYP2C9 substrates where decreases in the plasma concentration of these drugs may reduce their activity. Hormonal Contraceptives: Progestin and ethinyl estradiol are CYP3A4 substrates. Concomitant use of CAMZYOS may decrease exposures of ethinyl estradiol and progestin, which may lead to contraceptive failure or an increase in breakthrough bleeding. Advise patients to use a contraceptive method that is not affected by CYP 450 enzyme induction (e.g., intrauterine system) or add nonhormonal contraception (such as condoms) during concomitant use and for 4 months after the last dose of CAMZYOS. Drugs That Reduce Cardiac Contractility Expect additive negative inotropic effects of CAMZYOS and other drugs that reduce cardiac contractility. Avoid concomitant use of CAMZYOS in patients on disopyramide, ranolazine, verapamil with a beta blocker, or diltiazem with a beta blocker as these medications and combinations increase the risk of left ventricular systolic dysfunction and heart failure symptoms and clinical experience is limited. If concomitant therapy with a negative inotrope is initiated, or if the dose of a negative inotrope is increased, monitor LVEF closely until stable doses and clinical response have been achieved. SPECIFIC POPULATIONS Pregnancy CAMZYOS may cause fetal harm when administered to a pregnant female. Advise pregnant females about the potential risk to the fetus with maternal exposure to CAMZYOS during pregnancy. There is a pregnancy safety study for CAMZYOS. If CAMZYOS is administered during pregnancy, or if a patient becomes pregnant while receiving CAMZYOS or within 4 months after the last dose of CAMZYOS, healthcare providers should report CAMZYOS exposure by contacting Bristol Myers Squibb at 1-800-721-5072 or . Lactation The presence of CAMZYOS in human or animal milk, the drug’s effects on the breastfed infant, or the effects on milk production are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for CAMZYOS and any potential adverse effects on the breastfed child from CAMZYOS or from the underlying maternal condition. Females and Males of Reproductive Potential Confirm absence of pregnancy in females of reproductive potential prior to initiation of CAMZYOS. Advise females of reproductive potential to use effective contraception during treatment with CAMZYOS and for 4 months after the last dose. Use of CAMZYOS may reduce the effectiveness of CHCs. Advise patients using CHCs to use an alternative contraceptive method or add nonhormonal contraception. Please see U.S. Full Prescribing Information, including Boxed WARNING and Medication Guide. About ELIQUIS ® (apixaban) ELIQUIS® is an oral selective Factor Xa inhibitor. By inhibiting Factor Xa, a key blood clotting protein, ELIQUIS decreases thrombin generation and blood clot formation. ELIQUIS is approved for multiple indications in the U.S. based on efficacy and safety data from multiple Phase 3 clinical trials. ELIQUIS is a prescription medicine indicated to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF); for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE), in patients who have undergone hip or knee replacement surgery; for the treatment of DVT and PE; and to reduce the risk of recurrent DVT and PE, following initial therapy. ELIQUIS continues to be developed and commercialized by The Bristol Myers Squibb-Pfizer Alliance. ELIQUIS Important Safety Information Indications ELIQUIS is indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. ELIQUIS is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE), in patients who have undergone hip or knee replacement surgery. ELIQUIS is indicated for the treatment of DVT and PE, and to reduce the risk of recurrent DVT and PE following initial therapy. Important Safety Information WARNING: (A) PREMATURE DISCONTINUATION OF ELIQUIS INCREASES THE RISK OF THROMBOTIC EVENTS, (B) SPINAL/EPIDURAL HEMATOMA (A) Premature discontinuation of any oral anticoagulant, including ELIQUIS, increases the risk of thrombotic events. If anticoagulation with ELIQUIS is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant. (B) Epidural or spinal hematomas may occur in patients treated with ELIQUIS who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include: use of indwelling epidural catheters concomitant use of other drugs that affect hemostasis, such as nonsteroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants a history of traumatic or repeated epidural or spinal punctures a history of spinal deformity or spinal surgery optimal timing between the administration of ELIQUIS and neuraxial procedures is not known Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary. Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated. CONTRAINDICATIONS Active pathological bleeding Severe hypersensitivity reaction to ELIQUIS (e.g., anaphylactic reactions) WARNINGS AND PRECAUTIONS Increased Risk of Thrombotic Events after Premature Discontinuation: Premature discontinuation of any oral anticoagulant, including ELIQUIS, in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from ELIQUIS to warfarin in clinical trials in atrial fibrillation patients. If ELIQUIS is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant. Bleeding Risk: ELIQUIS increases the risk of bleeding and can cause serious, potentially fatal, bleeding. Concomitant use of drugs affecting hemostasis increases the risk of bleeding, including aspirin and other antiplatelet agents, other anticoagulants, heparin, thrombolytic agents, SSRIs, SNRIs, and NSAIDs. Advise patients of signs and symptoms of blood loss and to report them immediately or go to an emergency room. Discontinue ELIQUIS in patients with active pathological hemorrhage. The anticoagulant effect of apixaban can be expected to persist for at least 24 hours after the last dose (i.e., about two half-lives). An agent to reverse the anti-factor Xa activity of apixaban is available. Please visit for more information on availability of a specific reversal agent. Spinal/Epidural Anesthesia or Puncture: Patients treated with ELIQUIS undergoing spinal/epidural anesthesia or puncture may develop an epidural or spinal hematoma which can result in long-term or permanent paralysis. The risk of these events may be increased by the postoperative use of indwelling epidural catheters or the concomitant use of medicinal products affecting hemostasis. Indwelling epidural or intrathecal catheters should not be removed earlier than 24 hours after the last administration of ELIQUIS. The next dose of ELIQUIS should not be administered earlier than 5 hours after the removal of the catheter. The risk may also be increased by traumatic or repeated epidural or spinal puncture. If traumatic puncture occurs, delay the administration of ELIQUIS for 48 hours. Monitor patients frequently and if neurological compromise is noted, urgent diagnosis and treatment is necessary. Physicians should consider the potential benefit versus the risk of neuraxial intervention in ELIQUIS patients. Prosthetic Heart Valves: The safety and efficacy of ELIQUIS have not been studied in patients with prosthetic heart valves and is not recommended in these patients. Acute PE in Hemodynamically Unstable Patients or Patients who Require Thrombolysis or Pulmonary Embolectomy: Initiation of ELIQUIS is not recommended as an alternative to unfractionated heparin for the initial treatment of patients with PE who present with hemodynamic instability or who may receive thrombolysis or pulmonary embolectomy. Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholipid Syndrome (APS): Direct-acting oral anticoagulants (DOACs), including ELIQUIS, are not recommended for use in patients with triple-positive APS. For patients with APS (especially those who are triple positive [positive for lupus anticoagulant, anticardiolipin, and anti–beta 2-glycoprotein I antibodies]), treatment with DOACs has been associated with increased rates of recurrent thrombotic events compared with vitamin K antagonist therapy. ADVERSE REACTIONS The most common and most serious adverse reactions reported with ELIQUIS were related to bleeding. TEMPORARY INTERRUPTION FOR SURGERY AND OTHER INTERVENTIONS ELIQUIS should be discontinued at least 48 hours prior to elective surgery or invasive procedures with a moderate or high risk of unacceptable or clinically significant bleeding. ELIQUIS should be discontinued at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding or where the bleeding would be noncritical in location and easily controlled. Bridging anticoagulation during the 24 to 48 hours after stopping ELIQUIS and prior to the intervention is not generally required. ELIQUIS should be restarted after the surgical or other procedures as soon as adequate hemostasis has been established. DRUG INTERACTIONS Combined P-gp and Strong CYP3A4 Inhibitors: Inhibitors of P-glycoprotein (P-gp) and cytochrome P450 3A4 (CYP3A4) increase exposure to apixaban and increase the risk of bleeding. For patients receiving ELIQUIS doses of 5 mg or 10 mg twice daily, reduce the dose of ELIQUIS by 50% when ELIQUIS is coadministered with drugs that are combined P-gp and strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, or ritonavir). In patients already taking 2.5 mg twice daily, avoid coadministration of ELIQUIS with combined P-gp and strong CYP3A4 inhibitors. Clarithromycin Although clarithromycin is a combined P-gp and strong CYP3A4 inhibitor, pharmacokinetic data suggest that no dose adjustment is necessary with concomitant administration with ELIQUIS. Combined P-gp and Strong CYP3A4 Inducers: Avoid concomitant use of ELIQUIS with combined P-gp and strong CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort) because such drugs will decrease exposure to apixaban. Anticoagulants and Antiplatelet Agents: Coadministration of antiplatelet agents, fibrinolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. APPRAISE-2, a placebo-controlled clinical trial of apixaban in high-risk post-acute coronary syndrome patients treated with aspirin or the combination of aspirin and clopidogrel, was terminated early due to a higher rate of bleeding with apixaban compared to placebo. PREGNANCY The limited available data on ELIQUIS use in pregnant women are insufficient to inform drug-associated risks of major birth defects, miscarriage, or adverse developmental outcomes. Treatment may increase the risk of bleeding during pregnancy and delivery, and in the fetus and neonate. Labor or delivery: ELIQUIS use during labor or delivery in women who are receiving neuraxial anesthesia may result in epidural or spinal hematomas. Consider use of a shorter acting anticoagulant as delivery approaches. LACTATION Breastfeeding is not recommended during treatment with ELIQUIS. FEMALES AND MALES OF REPRODUCTIVE POTENTIAL Females of reproductive potential requiring anticoagulation should discuss pregnancy planning with their physician. The risk of clinically significant uterine bleeding, potentially requiring gynecological surgical interventions, identified with oral anticoagulants including ELIQUIS should be assessed in these patients and those with abnormal uterine bleeding.
