Heartburn

FLORHAM PARK, N.J., Oct. 27, 2024 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal (GI) diseases, today announced that the company will present data from multiple investigational studies for its first-in-class treatment VOQUEZNA® (vonoprazan) tablets at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting, being held October 25-30 in Philadelphia, PA. VOQUEZNA is approved for the relief of heartburn associated with Non-Erosive Gastroesophageal Reflux Disease (Non-Erosive GERD), for the treatment of all severities of Erosive Esophagitis, commonly referred to as Erosive GERD, and relief of related heartburn, and in combination with antibiotics for the eradication of Helicobacter pylori (H. pylori) infection.1 VOQUEZNA is the first and only U.S. Food and Drug Administration (FDA)-approved potassium-competitive acid blocker (PCAB).2 Evaluating On-Demand VOQUEZNA Treatment from the PHALCON-NERD-201 Trial3In an oral presentation being presented Monday, October 28 at ACG, Ronnie Fass, M.D., director of the Division of Gastroenterology and Hepatology and medical director of the Digestive Health Center at MetroHealth in Cleveland, Ohio, and lead investigator of the PHALCON-NERD-201 trial, will provide results from a post-hoc analysis of the Phase 2 study. This research, recognized with the ACG Outstanding Research Award in the ‘Esophagus’ category, evaluated the efficacy of As Needed (On-Demand) dosing of VOQUEZNA, compared to placebo, for relief of episodic heartburn in participants with Non-Erosive GERD following a 4-week VOQUEZNA daily dosing “run-in” period. As previously reported, the primary analysis of the study demonstrated that all three VOQUEZNA doses tested (10 mg, 20 mg and 40 mg) had higher percentages of heartburn completely relieved within three hours of dosing and sustained for 24 hours, with significant differences reported as early as one hour. Use of As Needed dosing in this population is investigational as VOQUEZNA has been neither evaluated nor approved by the FDA as an As Needed treatment for Non-Erosive GERD. To understand the practical application of As Needed dosing for VOQUEZNA, the new analysis examined daily heartburn symptom burden at baseline, during daily VOQUEZNA treatment, and upon switching to As Needed treatment after achieving symptom control during the run-in period. It also further evaluated the rate of symptom improvement upon treating new onset heartburn episodes during the As Needed dosing period.3 “As a healthcare provider, the concept of a novel As Needed dosing option for Non-Erosive GERD is highly compelling. I am pleased that ACG has recognized this data as a recipient of the ACG Outstanding Research Award, further reinforcing its importance to the GI community,” said Ronnie Fass, M.D. “The low frequency of heartburn after discontinuing daily VOQUEZNA treatment, coupled with the rapid onset of improvement following As Needed dosing, suggests that transitioning from daily dosing to As Needed treatment is a viable option for patients who previously respond well to daily therapy of VOQUEZNA. These promising results warrant further investigation in a larger and extended As Needed study period.” The double-blind, placebo-controlled PHALCON-NERD Phase 2 study randomized 207 patients who were eligible for On-Demand (“As Needed”) treatment following a 4-week daily dosing run-in period in which patients received VOQUEZNA 20 mg once-daily. Patients without heartburn in the last seven days of the run-in period were evenly randomized to receive 10 mg, 20 mg or 40 mg of VOQUEZNA, or placebo, for six weeks. Results of the study were published in Alimentary Pharmacology & Therapeutics in September 2023.4 Results:3 Patients eligible for the On-Demand period (n=207) were highly symptomatic with a reported mean of 16.1% [95% CI: (13.5%, 18.7%)] heartburn-free days during screening. Heartburn-free days increased during the run-in period to a mean of 82.9% [95% CI: (80.4%, 85.4%)] and remained well above pre-treatment levels (means 71% to 75%) throughout the six-week On-Demand period.The difference in the improvement of treated heartburn episodes between the active and placebo groups became evident within the first hour of dosing (10 mg [75.5%, p<0.0001], 20 mg [69.1%, p = 0.0010], 40 mg [75.5%, p<0.0001], placebo [57.0%]).Over 90% of heartburn episodes treated with VOQUEZNA improved within two hours. Non-Erosive GERD is the largest category of GERD and is characterized by reflux-related symptoms in the absence of esophageal mucosal erosions. An estimated 45 million U.S. adults are living with Non-Erosive GERD, and approximately 15 million are treated with a prescription medicine annually. Despite longstanding treatment options, many patients continue to suffer from heartburn symptoms. As Needed dosing is a unique and differentiated dosing regimen for which proton pump inhibitors (PPIs), a mainstay of GERD treatment, are not approved in the U.S.5 In July 2024, VOQUEZNA was approved by the FDA as a daily dosing treatment for the relief of heartburn associated with Non-Erosive GERD in adults.1 Nocturnal GERD Symptoms in Non-Erosive GERD6 In a poster presentation on Monday, October 28 at ACG, which has received ACG’s Presidential Poster Award, Dr. Catiele Antunes, M.D., Yale New Haven Hospital, will present data looking at the common, yet infrequently evaluated, nocturnal symptoms among patients with Non-Erosive GERD. The study included an exploratory analysis of a validated patient-reported outcomes scale, the Nocturnal Gastro-esophageal reflux disease Symptom Severity and Impact Questionnaire (N-GSSIQ), to determine the severity, morning impact, and concern about nocturnal GERD. “We are very pleased to continue to add to the body of clinical research evaluating the potential benefits of VOQUEZNA for GERD patients,” said Eckhard Leifke, M.D., Chief Medical Officer at Phathom. “In our study, patients who experienced nocturnal GERD symptoms prior to VOQUEZNA treatment found effective and meaningful relief with daily dosing, reinforcing its potent and durable acid suppression profile in helping to address both daytime and nighttime heartburn. While these findings are exploratory, they show promise for the many individuals suffering from nocturnal GERD symptoms.” Results:6 Among 772 subjects, the mean percentage of heartburn-free nights during the screening period was 29.6%, 25.8% and 31.1%, for patients randomized to placebo, VOQUEZNA 10 mg and 20 mg, respectively.After 4 weeks, the least-square (LS) mean percentage of heartburn-free nights was significantly better with 59.9% for VOQUEZNA 10 mg (LS mean difference=16.5%, p<0.0001 vs. placebo), and 56.4% for VOQUEZNA 20 mg (LS mean difference=13.1%, p<0.0001 vs. placebo), compared to 43.3% for placebo. The median percentage of heartburn-free nights was 70.4% for VOQUEZNA 10 mg and 71.0% for VOQUEZNA 20 mg, compared to 45.5% for placebo.N-GSSIQ scores showed significant improvement with VOQUEZNA compared to placebo in total score (LS mean difference vs. placebo of -2.9 and -1.8 for VOQUEZNA 10 mg and 20 mg, respectively; p<0.005 for both comparisons), nocturnal symptom severity (LS mean difference vs. placebo of -5.4 and -3.5 for VOQUEZNA 10 mg and 20 mg; p<0.001 for both comparisons), and concern about nocturnal GERD (LS mean difference vs. placebo of -2.0 for both VOQUEZNA 10 mg and 20 mg; p<0.0001). In addition to these data presentations, Phathom will sponsor a product theater highlighting VOQUEZNA as an approved treatment for GERD and will also have a presence on the exhibit floor at booth #757 throughout the conference. Following the conclusion of ACG 2024, the abstracts will be posted to the publications and scientific section of the Phathom company website.

IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS VOQUEZNA is contraindicated in patients with a known hypersensitivity to vonoprazan or any component of VOQUEZNA, or in patients receiving rilpivirine-containing products. For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with VOQUEZNA, refer to the Contraindications section of the corresponding prescribing information. WARNINGS AND PRECAUTIONS Presence of Gastric Malignancy: In adults, symptomatic response to therapy with VOQUEZNA does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in patients who have a suboptimal response or an early symptomatic relapse after completing treatment with VOQUEZNA. In older patients, also consider endoscopy. Acute Tubulointerstitial Nephritis: Acute tubulointerstitial nephritis (TIN) has been reported with VOQUEZNA. If suspected, discontinue VOQUEZNA and evaluate patients with suspected acute TIN. Clostridioides difficile-Associated Diarrhea: Published observational studies suggest that proton pump inhibitors (PPIs) may be associated with an increased risk of Clostridioides difficile-associated diarrhea (CDAD), especially in hospitalized patients. VOQUEZNA may also increase the risk of CDAD. Consider CDAD in patients with diarrhea that does not improve. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. CDAD has been reported with use of nearly all antibacterial agents. For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with VOQUEZNA, refer to Warnings and Precautions section of the corresponding prescribing information. Bone Fracture: Several published observational studies suggest that PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine, especially in patients receiving high dose (multiple daily doses) and long-term therapy (a year or longer). Bone fracture, including osteoporosis-related fracture, has also been reported with vonoprazan. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. Patients at risk for osteoporosis-related fractures should be managed according to the established treatment guidelines. Severe Cutaneous Adverse Reactions (SCAR): Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported with VOQUEZNA. Discontinue VOQUEZNA at the first signs or symptoms of SCAR or other signs of hypersensitivity and consider further evaluation. Vitamin B12 (Cobalamin) Deficiency: Long-term use of acid-suppressing drugs can lead to malabsorption of Vitamin B12 caused by hypo- or achlorhydria. Vitamin B12 deficiency has been reported postmarketing with vonoprazan. If clinical symptoms consistent with vitamin B12 deficiency are observed in patients treated with VOQUEZNA, consider further workup. Hypomagnesemia and Mineral Metabolism: Hypomagnesemia has been reported postmarketing with vonoprazan. Hypomagnesemia may lead to hypocalcemia and/or hypokalemia and may exacerbate underlying hypocalcemia in at-risk patients. Consider monitoring magnesium levels prior to initiation of VOQUEZNA and periodically in patients expected to be on prolonged treatment, in patients taking drugs that may have increased toxicity in the presence of hypomagnesemia or drugs that may cause hypomagnesemia. Treatment of hypomagnesemia may require magnesium replacement and discontinuation of VOQUEZNA. Consider monitoring magnesium and calcium levels prior to initiation of VOQUEZNA and periodically while on treatment in patients with a preexisting risk of hypocalcemia. Supplement with magnesium and/or calcium, as necessary. If hypocalcemia is refractory to treatment, consider discontinuing VOQUEZNA. Interactions with Diagnostic Investigations for Neuroendocrine Tumors: Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors. Temporarily discontinue VOQUEZNA treatment at least 4 weeks before assessing CgA levels and consider repeating the test if initial CgA levels are high. Fundic Gland Polyps: Use of VOQUEZNA is associated with a risk of fundic gland polyps that increases with long-term use, especially beyond one year. Fundic gland polyps have been reported with vonoprazan in clinical trials and during postmarketing use with PPIs. Most patients who developed fundic gland polyps were asymptomatic and fundic gland polyps were identified incidentally on endoscopy. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. ADVERSE REACTIONS: Healing of Erosive GERD: The most common adverse reactions (≥2% of patients in the VOQUEZNA arm) include gastritis (3%), diarrhea (2%), abdominal distention (2%), abdominal pain (2%), and nausea (2%). Maintenance of Healed Erosive GERD: The most common adverse reactions (≥3% of patients in the VOQUEZNA arm) include gastritis (6%), abdominal pain (4%), dyspepsia (4%), hypertension (3%), and urinary tract infection (3%). Relief of Heartburn Associated with Non-Erosive GERD: The most common adverse reactions (≥2% of patients in the VOQUEZNA arm) include abdominal pain (2%), constipation (2%), diarrhea (2%), nausea (2%), and urinary tract infection (2%). Treatment of H. Pylori Infection (VOQUEZNA and Amoxicillin): The most common adverse reactions (≥2% in any treatment arm) include diarrhea (5%), abdominal pain (3%), vulvovaginal candidiasis (2%), nasopharyngitis (2%), dysgeusia (1%), headache (1%), and hypertension (1%). Treatment of H. Pylori Infection (VOQUEZNA, Amoxicillin and Clarithromycin): The most common adverse reactions (≥2% in any treatment arm) include dysgeusia (5%), diarrhea (4%), vulvovaginal candidiasis (3%), headache (3%), abdominal pain (2%), hypertension (2%), and nasopharyngitis (<1%). For more information on adverse reactions and laboratory changes with amoxicillin or clarithromycin, refer to Adverse Reactions section of the corresponding prescribing information. DRUG INTERACTIONS VOQUEZNA has the potential for clinically important drug interactions, including interactions with drugs dependent on gastric pH for absorption, drugs that are substrates for certain CYP enzymes, and some diagnostic tests. Avoid concomitant use of VOQUEZNA with atazanavir or nelfinavir. See full Prescribing Information for more details about important drug interactions. Consult the labeling of concomitantly used drugs to obtain further information about interactions with vonoprazan. For information about drug interactions, contraindications, and warnings and precautions of antibacterial agents (amoxicillin or clarithromycin) indicated in combination with VOQUEZNA, refer to their corresponding prescribing information. USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding is not recommended during treatment. Because of the potential risk of adverse liver effects shown in animal studies with vonoprazan, advise patients not to breastfeed during treatment with VOQUEZNA. Renal Impairment: For the healing of Erosive GERD, dosage reduction is recommended in patients with severe renal impairment (eGFR < 30 mL/min). Use of VOQUEZNA is not recommended for the treatment of H. pylori infection in patients with severe renal impairment.

VYLOY is the first and only CLDN18.2-targeted treatment approved in the U.S. for adults with advanced gastric and gastroesophageal junction cancer whose tumors are CLDN18.2 positive TOKYO, Oct. 18, 2024 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") today announced that the U.S. Food and Drug Administration (FDA) has approved VYLOY™ (zolbetuximab-clzb) in combination with fluoropyrimidine- and platinum-containing chemotherapy for the first-line treatment of adults with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors are claudin (CLDN) 18.2 positive as determined by an FDA-approved test.1 VYLOY is the first and only CLDN18.2-targeted therapy approved in the U.S. In the SPOTLIGHT and GLOW clinical trials, approximately 38% of patients screened had tumors that were CLDN18.2 positive.2,3 CLDN18.2 positivity is defined as ≥75% of tumor cells demonstrating moderate to strong membranous CLDN18 immunohistochemical staining, as determined by the VENTANA® CLDN18 (43-14A) RxDx Assay from Roche.2,3 Astellas collaborated with Roche on the newly approved immunohistochemistry (IHC) companion diagnostic (CDx) test to identify patients who may be eligible for VYLOY.4 Moitreyee Chatterjee-Kishore, Ph.D., M.B.A., Senior Vice President and Head of Immuno-Oncology Development, Astellas "The approval of VYLOY as the first and only targeted therapy for CLDN18.2-positive patients in the U.S. further delivers on our relentless pursuit of scientific progress for devastating diseases like gastric and GEJ cancers, which are often only discovered at the advanced stage. This achievement is the result of years of dedicated research and development focused on targeting a novel biomarker, and we are grateful to the patients, investigators, and Astellas team members who have made this important advancement for patients a reality." Samuel J. Klempner, M.D., Associate Professor, Harvard Medical School, M edical Oncologist at Massachusetts General Hospital, Boston "While there have been advances in the first-line treatment of locally advanced unresectable and metastatic gastric and GEJ cancers in the last several years, there is still a tremendous unmet need among our patients. The approval of VYLOY, based on the pivotal Phase 3 SPOTLIGHT and GLOW trials, brings forward a novel biomarker and new therapy for patients whose tumors are CLDN18.2 positive, and for those on the frontlines of treatment decision-making." The approval is based on results from the Phase 3 SPOTLIGHT and GLOW clinical trials.2,3 The SPOTLIGHT study evaluated VYLOY plus mFOLFOX6 (a combination chemotherapy regimen that includes oxaliplatin, leucovorin, and fluorouracil) compared to placebo plus mFOLFOX6. The GLOW study evaluated VYLOY plus CAPOX (a combination chemotherapy regimen that includes capecitabine and oxaliplatin) compared to placebo plus CAPOX. Both trials met their primary endpoint, progression-free survival (PFS), as well as a key secondary endpoint, overall survival (OS), in patients treated with VYLOY plus chemotherapy compared to placebo plus chemotherapy. Across the SPOTLIGHT and GLOW trials, the most common all-grade treatment-emergent adverse events (TEAEs) reported in the VYLOY treatment arms were nausea, vomiting and decreased appetite.2,3 An FDA-approved test is used to identify patients who may be eligible for VYLOY.1 The VENTANA CLDN18 (43-14A) RxDx Assay from Roche is an FDA-approved IHC test used to help determine CLDN18.2 status. Testing is available in the U.S. at multiple reference laboratories nationwide and is expected to expand to additional laboratories over time. To see where testing for CLDN18.2 status is available, please visit VYLOYhcp.com.* Following today's FDA decision, VYLOY is now approved in five markets worldwide — Japan, the United Kingdom, the European Union, South Korea and the U.S. Japan's Ministry of Health, Labour and Welfare approved VYLOY for use on March 26, 2024, representing the first global approval of this treatment. In August, VYLOY was approved by the UK Medicines and Healthcare products Regulatory Agency. In September, the European Commission granted marketing authorization to VYLOY in the European Union, and the Ministry of Food and Drug Safety approved the therapy in South Korea.

As a first-in-class monoclonal antibody (mAb), VYLOY targets and binds to CLDN18.2, a transmembrane protein. VYLOY depletes CLDN18.2-positive cells via antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC).1 VYLOY (zolbetuximab-clzb) U.S. Indication & Important Safety Information INDICATION VYLOY, in combination with fluoropyrimidine- and platinum-containing chemotherapy, is indicated for the first-line treatment of adults with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors are claudin (CLDN) 18.2 positive as determined by an FDA-approved test. IMPORTANT SAFETY INFORMATION Warnings and Precautions Hypersensitivity reactions, including serious anaphylaxis reactions, and serious and fatal infusion-related reactions (IRR) have been reported in clinical studies when VYLOY has been administered. Any grade hypersensitivity reactions, including anaphylactic reactions, occurring with VYLOY in combination with mFOLFOX6 or CAPOX was 18%. Severe (Grade 3 or 4) hypersensitivity reactions, including anaphylactic reactions, occurred in 2% of patients. Seven patients (1.3%) permanently discontinued VYLOY for hypersensitivity reactions, including two patients (0.4%) who permanently discontinued VYLOY due to anaphylactic reactions. Seventeen (3.2%) patients required dose interruption, and three patients (0.6%) required infusion rate reduction due to hypersensitivity reactions. All grade IRRs occurred in 3.2% in patients administered VYLOY in combination with mFOLFOX6 or CAPOX. Severe (Grade 3) IRRs occurred in 2 (0.4%) patients who received VYLOY. An IRR led to permanent discontinuation of VYLOY in 2 (0.4%) patients and dose interruption in 7 (1.3%) patients. The infusion rate was reduced for VYLOY for 2 (0.4%) patients due to an IRR. Monitor patients during infusion with VYLOY and for 2 hours after completion of infusion or longer if clinically indicated, for hypersensitivity reactions with symptoms and signs that are highly suggestive of anaphylaxis (urticaria, repetitive cough, wheeze and throat tightness/change in voice). Monitor patients for signs and symptoms of IRRs including nausea, vomiting, abdominal pain, salivary hypersecretion, pyrexia, chest discomfort, chills, back pain, cough and hypertension. If a severe or life-threatening hypersensitivity or IRR reaction occurs, discontinue VYLOY permanently, treat symptoms according to standard medical care, and monitor until symptoms resolve. For any Grade 2 hypersensitivity or IRR, interrupt the VYLOY infusion until Grade ≤1, then resume at a reduced infusion rate for the remaining infusion. Follow Grade 2 management for Grade 3 infusion-related nausea and vomiting. Premedicate the patient with antihistamines for the subsequent infusions, and closely monitor the patient for symptoms and signs of a hypersensitivity reaction. The infusion rate may be gradually increased as tolerated. Severe Nausea and Vomiting. VYLOY is emetogenic. Nausea and vomiting occurred more often during the first cycle of treatment . All grade nausea and vomiting occurred in 82% and 67% respectively of patients treated with VYLOY in combination with mFOLFOX6 and 69% and 66% in combination with CAPOX, respectively. Severe (Grade 3) nausea occurred in 16% and 9% of patients treated with VYLOY in combination with mFOLFOX6 or CAPOX respectively. Severe (Grade 3) vomiting occurred in 16% and 12% of patients treated with VYLOY in combination with mFOLFOX6 or CAPOX. Nausea led to permanent discontinuation of VYLOY in combination with mFOLFOX6 or CAPOX in 18 (3.4%) patients and dose interruption in 147 (28%) patients. Vomiting led to permanent discontinuation of VYLOY in combination with mFOLFOX6 or CAPOX in 20 (3.8%) patients and dose interruption in 150 (28%) patients. Pretreat with antiemetics prior to each infusion of VYLOY. Manage patients during and after infusion with antiemetics or fluid replacement. Interrupt the infusion, or permanently discontinue VYLOY based on severity. ADVERSE REACTIONS Most common adverse reactions (≥15%): Nausea, vomiting, fatigue, decreased appetite, diarrhea, peripheral sensory neuropathy, abdominal pain, constipation, decreased weight, hypersensitivity reactions, and pyrexia.

About Locally Advanced Unresectable Metastatic Gastric and Gastroesophageal Junction Cancer Gastric and gastroesophageal junction (G/GEJ) cancer is the fifth most commonly diagnosed cancer worldwide.5 GEJ adenocarcinoma is a cancer that starts at the area where the esophagus joins the stomach.6 In the U.S., it is estimated that 130,263 people are living with G/GEJ cancer, classifying it as a rare disease.7,8 In 2024, it is estimated that 26,890 people will be diagnosed with G/GEJ cancer and 10,880 will die from the disease in the U.S.7 Signs and symptoms can include indigestion or heartburn, pain or discomfort in the abdomen, nausea and vomiting, bloating of the stomach after meals and loss of appetite.9 Signs of more advanced G/GEJ cancer can include unexplained weight loss, weakness and fatigue, and vomiting blood or having blood in the stool.10 Risk factors associated with gastric and GEJ cancer can include older age, male gender, family history, H. pylori infection, smoking, and gastroesophageal reflux disease (GERD).11,12 Because early-stage gastric cancer symptoms frequently overlap with more common stomach-related conditions, G/GEJ cancer is often diagnosed in the advanced or metastatic stage, or once it has spread from the tumor's origin to other body tissues or organs.10 The five-year relative survival rate for patients at the metastatic stage is 7%.7 INVESTIGATIONAL STUDIES About SPOTLIGHT Phase 3 Clinical Trial SPOTLIGHT is a Phase 3, global, multi-center, double-blind, randomized study, assessing the efficacy and safety of zolbetuximab plus mFOLFOX6 (a combination chemotherapy regimen that includes oxaliplatin, leucovorin, and fluorouracil) compared to placebo plus mFOLFOX6 as a first-line treatment in patients with locally advanced unresectable or metastatic HER2-negative gastric or GEJ adenocarcinoma whose tumors were CLDN18.2 positive. The study enrolled 565 patients at 215 study locations in the U.S., Canada, United Kingdom, Australia, Europe, South America, and Asia. The primary endpoint is progression-free survival (PFS) in participants treated with the combination of zolbetuximab plus mFOLFOX6 compared to those treated with placebo plus mFOLFOX6. Secondary endpoints include overall survival (OS), objective response rate (ORR), duration of response (DOR), safety and tolerability, and quality-of-life parameters. Data from the SPOTLIGHT clinical trial were presented during the 2023 American Society of Clinical Oncology (ASCO) Gastrointestinal (GI) Cancers Symposium in an oral presentation on January 19, 2023, and were subsequently published in The Lancet on April 14, 2023.2 For more information, please visit clinicaltrials.gov under Identifier NCT03504397. About GLOW Phase 3 Clinical Trial GLOW is a Phase 3, global, multi-center, double-blind, randomized study, assessing the efficacy and safety of zolbetuximab plus CAPOX (a combination chemotherapy regimen that includes capecitabine and oxaliplatin) compared to placebo plus CAPOX as a first-line treatment in patients with locally advanced unresectable or metastatic HER2-negative gastric or GEJ adenocarcinoma whose tumors were CLDN18.2 positive. The study enrolled 507 patients at 166 study locations in the U.S., Canada, United Kingdom, Europe, South America, and Asia. The primary endpoint is PFS in participants treated with the combination of zolbetuximab plus CAPOX compared to those treated with placebo plus CAPOX. Secondary endpoints include OS, ORR, DOR, safety and tolerability, and quality-of-life parameters. Data from the GLOW study were initially presented at the March 2023 ASCO Plenary Series with an updated oral presentation at the 2023 ASCO Annual Meeting on June 3, 2023, and were subsequently published in Nature Medicine on July 31, 2023.3 For more information, please visit clinicaltrials.gov under Identifier NCT03653507. Investigational Pipeline in CLDN18.2 A Phase 2 trial of zolbetuximab in metastatic pancreatic adenocarcinoma is in progress. The trial is a randomized, multi-center, open-label study, evaluating the safety and efficacy of investigational zolbetuximab in combination with gemcitabine plus nab-paclitaxel as a first-line treatment in patients with metastatic pancreatic adenocarcinoma with CLDN18.2 positive tumors (defined as ≥75% of tumor cells demonstrating moderate to strong membranous CLDN18 staining based on a validated immunohistochemistry assay). For more information, please visit clinicaltrials.gov under Identifier NCT03816163.

Patent covers proprietary method using methylation of the CCNA1 gene to help detect esophageal precancer and cancer NEW YORK, Oct. 15, 2024 /PRNewswire/ -- Lucid Diagnostics Inc. (Nasdaq: LUCD) ("Lucid" or the "Company"), a commercial-stage, cancer prevention medical diagnostics company, and subsidiary of PAVmed Inc. (Nasdaq: PAVM), today announced that it has received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for a patent application covering its proprietary method of using methylation of the cyclin-A1 (CCNA1) gene to help detect esophageal precancer and cancer, a key component of its EsoGuard® Esophageal DNA Test. "This patent strengthens the already robust intellectual property portfolio underlying our groundbreaking technologies and will provide strong protection for the CCNA1 methylation assay method which is at the heart of the EsoGuard assay," said Lishan Aklog, M.D., Lucid's Chairman and Chief Executive Officer. "The allowance validates our strategy of focusing on the laboratory methods of our assay—a strategy we will continue to aggressively pursue for other components of the assay." EsoGuard utilizes next-generation sequencing (NGS) to assess DNA methylation at 31 sites on two genes, vimentin (VIM) and cyclin-A1 (CCNA1). Such methylation has been shown to be strongly associated with conditions along the spectrum from early esophageal precancer (non-dysplastic Barrett's Esophagus or BE), to late precancer (dysplastic BE), to cancer (esophageal adenocarcinoma). Although VIM methylation had been previously associated with gastrointestinal neoplasias, the association of CCNA1 methylation with esophageal neoplasia is novel and appears to be more specific. The technology behind EsoGuard and the EsoCheck® Esophageal Cell Collection Device was developed at Case Western Reserve University (CWRU) by faculty members Sanford Markowitz, M.D., PhD, Amitabh Chak, M.D., and Joseph Willis, M.D., with the support of research funds from the National Institutes of Health (NIH) and elsewhere. Lucid holds the exclusive worldwide license to commercialize this technology. The successful transfer of the assay from the academic research laboratory and its subsequent commercialization was the result of close, ongoing collaboration between Lucid and CWRU. About Lucid Diagnostics Lucid Diagnostics Inc. is a commercial-stage, cancer prevention medical diagnostics company and subsidiary of PAVmed Inc. (Nasdaq: PAVM). Lucid is focused on the millions of patients with gastroesophageal reflux disease (GERD), also known as chronic heartburn, who are at risk of developing esophageal precancer and cancer. Lucid's EsoGuard® Esophageal DNA Test, performed on samples collected in a brief, noninvasive office procedure with its EsoCheck® Esophageal Cell Collection Device, represent the first and only commercially available tools designed with the goal of preventing cancer and cancer deaths through widespread, early detection of esophageal precancer in at-risk patients.

Forward-Looking Statements This press release includes forward-looking statements that involve risk and uncertainties. Forward-looking statements are any statements that are not historical facts. Such forward-looking statements, which are based upon the current beliefs and expectations of Lucid's management, are subject to risks and uncertainties, which could cause actual results to differ from the forward-looking statements. Risks and uncertainties that may cause such differences include, among other things, volatility in the price of Lucid's common stock; general economic and market conditions; the uncertainties inherent in research and development, including the cost and time required to advance Lucid's products to regulatory submission; whether regulatory authorities will be satisfied with the design of and results from Lucid's clinical and preclinical studies; whether and when Lucid's products are cleared by regulatory authorities; market acceptance of Lucid's products once cleared and commercialized; Lucid's ability to raise additional funding as needed; and other competitive developments. In addition, Lucid continues to monitor the COVID-19 pandemic and the pandemic's impact on Lucid's businesses. These factors are difficult or impossible to predict accurately and many of them are beyond Lucid's control. In addition, new risks and uncertainties may arise from time to time and are difficult to predict.
