First and only immunotherapy to demonstrate survival benefit in this setting in a global Phase III trial WILMINGTON, Del.--(BUSINESS WIRE)-- Positive high-level results of the ADRIATIC Phase III trial showed AstraZeneca’s IMFINZI® (durvalumab) demonstrated a statistically significant and clinically meaningful improvement in the dual primary endpoints of overall survival (OS) and progression-free survival (PFS) in patients with limited-stage small cell lung cancer (LS-SCLC) who had not progressed following concurrent chemoradiotherapy (cCRT) compared to placebo after cCRT. Small cell lung cancer (SCLC) is a highly aggressive form of lung cancer that typically recurs and progresses rapidly despite initial response to chemotherapy and radiotherapy in LS-SCLC patients.1,2 The prognosis is particularly poor for LS-SCLC, as only 15-30% of these patients will be alive five years after diagnosis.3 Suresh Senan, PhD, Professor of Clinical Experimental Radiotherapy at the Amsterdam University Medical Center, The Netherlands, and principal investigator in the trial said: “Many patients treated for limited-stage small cell lung cancer face disease recurrence and the standard of care has remained unchanged for decades. ADRIATIC is the first global Phase III immunotherapy trial to deliver significant, clinically meaningful improvement in survival in this setting, marking a breakthrough for patients with this devastating disease.” Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “These exciting results build on the transformative efficacy of IMFINZI in extensive-stage small cell lung cancer and demonstrate the potential to bring a curative-intent immunotherapy treatment to this earlier-stage setting of small cell lung cancer for the first time. These data, together with the PACIFIC data in unresectable, Stage III non-small cell lung cancer, underscore the pioneering role of IMFINZI in the treatment of early lung cancer following chemoradiotherapy.” The safety pro IMFINZI was consistent with its known profile, and no new safety signals were identified. These data will be presented at a forthcoming medical meeting and shared with global regulatory authorities. The second experimental arm testing the efficacy of IMJUDO® (tremelimumab-actl) added to IMFINZI as a secondary endpoint remains blinded and will continue to the next planned analysis. IMFINZI is approved in the US, EU, Japan, China and many other countries around the world for the treatment of extensive-stage SCLC (ES-SCLC) based on the CASPIAN Phase III trial. IMFINZI is also the only approved immunotherapy and the global standard of care in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after CRT based on the PACIFIC Phase III trial. IMPORTANT SAFETY INFORMATION There are no contraindications for IMFINZI® (durvalumab) or IMJUDO® (tremelimumab-actl). Severe and Fatal Immune-Mediated Adverse Reactions Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment or after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis IMFINZI and IMJUDO can cause immune-mediated pneumonitis, which may be fatal. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. IMFINZI as a Single Agent In patients who did not receive recent prior radiation, the incidence of immune-mediated pneumonitis was 2.4% (34/1414), including fatal (<0.1%), and Grade 3-4 (0.4%) adverse reactions. In patients who received recent prior radiation, the incidence of pneumonitis (including radiation pneumonitis) in patients with unresectable Stage III NSCLC following definitive chemoradiation within 42 days prior to initiation of IMFINZI in PACIFIC was 18.3% (87/475) in patients receiving IMFINZI and 12.8% (30/234) in patients receiving placebo. Of the patients who received IMFINZI (475), 1.1% were fatal and 2.7% were Grade 3 adverse reactions. The frequency and severity of immune-mediated pneumonitis in patients who did not receive definitive chemoradiation prior to IMFINZI were similar in patients who received IMFINZI as a single agent or with ES-SCLC or BTC when given in combination with chemotherapy. IMFINZI with IMJUDO Immune‑mediated pneumonitis occurred in 1.3% (5/388) of patients receiving IMFINZI and IMJUDO, including fatal (0.3%) and Grade 3 (0.2%) adverse reactions. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated pneumonitis occurred in 3.5% (21/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including fatal (0.5%), and Grade 3 (1%) adverse reactions. Immune-Mediated Colitis IMFINZI with IMJUDO and platinum-based chemotherapy can cause immune-mediated colitis, which may be fatal. IMFINZI and IMJUDO can cause immune-mediated colitis that is frequently associated with diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. IMFINZI as a Single Agent Immune-mediated colitis occurred in 2% (37/1889) of patients receiving IMFINZI, including Grade 4 (<0.1%) and Grade 3 (0.4%) adverse reactions.

Infusion-Related Reactions IMFINZI and IMJUDO can cause severe or life-threatening infusion-related reactions. Monitor for signs and symptoms of infusion-related reactions. Interrupt, slow the rate of, or permanently discontinue IMFINZI and IMJUDO based on the severity. See USPI Dosing and Administration for specific details. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses. IMFINZI as a Single Agent Infusion-related reactions occurred in 2.2% (42/1889) of patients receiving IMFINZI, including Grade 3 (0.3%) adverse reactions. IMFINZI with IMJUDO Infusion-related reactions occurred in 10 (2.6%) patients receiving IMFINZI and IMJUDO.

Complications of Allogeneic HSCT after IMFINZI Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/L-1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/L-1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/L-1 blocking antibodyPD-1/L-1 blocking antibody prior to or after an allogeneic HSCT. Embryo-Fetal Toxicity Based on their mechanism of action and data from animal studies, IMFINZI and IMJUDO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. In females of reproductive potential, verify pregnancy status prior to initiating IMFINZI and IMJUDO and advise them to use effective contraception during treatment with IMFINZI and IMJUDO and for 3 months after the last dose of IMFINZI and IMJUDO. Lactation There is no information regarding the presence of IMFINZI and IMJUDO in human milk; however, because of the potential for serious adverse reactions in breastfed infants from IMFINZI and IMJUDO, advise women not to breastfeed during treatment and for 3 months after the last dose.

Notes Small cell lung cancer Lung cancer is the leading cause of cancer death among men and women and accounts for about one-fifth of all cancer deaths.4 Lung cancer is broadly split into NSCLC and SCLC, with about 15% of cases classified as SCLC.5 LS-SCLC (Stage I-III) is classified as SCLC that is generally only in one lung or one side of the chest.6 LS-SCLC accounts for approximately 30% of SCLC diagnoses and the prognosis remains poor despite curative-intent treatment with standard-of-care cCRT.7 ADRIATIC The ADRIATIC trial is a randomized, double-blind, placebo-controlled, multi-center global Phase III trial evaluating IMFINZI monotherapy and IMFINZI plus IMJUDO versus placebo in the treatment of 730 patients with LS-SCLC who had not progressed following cCRT. In the experimental arms, patients were randomized to receive a 1500mg fixed dose of IMFINZI with or without IMJUDO 75mg every four weeks for up to four doses/cycles each, followed by IMFINZI every four weeks for up to 24 months. The dual primary endpoints are PFS and OS for IMFINZI monotherapy versus placebo. Key secondary endpoints included OS and PFS for IMFINZI plus IMJUDO versus placebo, safety and quality of life measures. The trial includes 164 centers in 19 countries across North and South America, Europe and Asia. IMFINZI® (durvalumab) IMFINZI® (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor’s immune-evading tactics and releasing the inhibition of immune responses. In addition to its indications in unresectable, Stage III NSCLC and ES-SCLC, IMFINZI is currently approved in a number of countries in combination with a short course of IMJUDO and chemotherapy for the treatment of metastatic NSCLC. IMFINZI is also approved in a number of countries in combination with chemotherapy in locally advanced or metastatic biliary tract cancer and in combination with IMJUDO in unresectable hepatocellular carcinoma (HCC). IMFINZI is also approved as a monotherapy in unresectable HCC in Japan and the EU and in previously treated patients with advanced bladder cancer in a small number of countries. Since the first approval in May 2017, more than 220,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with SCLC, NSCLC, bladder cancer, breast cancer, several gastrointestinal cancers and other solid tumors. IMJUDO® (tremelimumab-actl) IMJUDO® (tremelimumab-actl) is a human monoclonal antibody that targets the activity of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). IMJUDO blocks the activity of CTLA-4, contributing to T-cell activation, priming the immune response to cancer and fostering cancer cell death. In addition to its approved indications in combination with IMFINZI in liver and lung cancers, the combination of IMJUDO and IMFINZI is being evaluated across multiple tumor types including locoregional HCC (EMERALD-3) and bladder cancer (VOLGA and NILE).
