DARMSTADT, Germany and NEW YORK, March 13, 2020 /PRNewswire/ -- Merck and Pfizer Inc. (NYSE: PFE) today announced an update from the Phase III JAVELIN Head and Neck 100 study evaluating avelumab in addition to chemoradiotherapy (CRT) versus standard-of-care CRT in patients with untreated locally advanced squamous cell carcinoma of the head and neck (LA SCCHN). The alliance has accepted the recommendation of the independent Data Monitoring Committee (DMC) to terminate the JAVELIN Head and Neck 100 trial, as the study is unlikely to show a statistically significant improvement in the primary endpoint of progression-free survival (PFS) based on a preplanned interim analysis. A detailed analysis of the Phase III JAVELIN Head and Neck 100 study is being conducted and study findings will be shared with the scientific community.
There has been limited innovation for patients with locally advanced SCCHN over the past 10 years.1 Despite aggressive standard-of-care treatment with high-dose chemotherapy combined with radiotherapy, LA SCCHN will ultimately recur in a large proportion of patients.2 In recognition of the unmet need for additional treatment options that can prevent recurrence or metastatic disease,3 the alliance initiated the JAVELIN Head and Neck 100 trial, which is the first Phase III study to report topline results for an immune checkpoint inhibitor in combination with CRT in LA SCCHN.
About JAVELIN Head and Neck 100
JAVELIN Head and Neck 100 (NCT02952586) is a Phase III, randomized, double-blind, placebo-controlled, parallel-arm study investigating treatment with avelumab plus standard-of-care CRT followed by avelumab maintenance versus CRT alone in patients with previously untreated LA SCCHN. A total of 697 patients who had not received prior therapy for locally advanced SCCHN and were eligible for CRT with curative intent were randomly assigned to receive avelumab plus CRT or CRT alone. The primary endpoint was PFS per modified Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Secondary endpoints included overall survival (OS), time to locoregional failure, time to distant metastatic failure, overall response, duration of response and pathologic complete response.
About Head and Neck Cancer
Head and neck cancer is the sixth most common cancer worldwide.4 In 2016, there were nearly 150,000 newly diagnosed cases in the United States, Japan and Europe.4 Approximately 60% of people are diagnosed with head and neck cancer when their disease has already progressed to the locally advanced stage (Stage III-IVB).5 At this stage, the cancer has spread from its site of origin to local lymph nodes, but not another part of the body.6 Standard of care for these patients includes high-dose chemotherapy combined with radiotherapy.7
About BAVENCIO® (avelumab)
BAVENCIO is a human anti-programmed death ligand-1 (PD-L1) antibody. BAVENCIO has been shown in preclinical models to engage both the adaptive and innate immune functions. By blocking the interaction of PD-L1 with PD-1 receptors, BAVENCIO has been shown to release the suppression of the T cell-mediated antitumor immune response in preclinical models.8-10 In November 2014, Merck and Pfizer announced a strategic alliance to co-develop and co-commercialize BAVENCIO.
BAVENCIO Approved Indications
The European Commission has authorized the use of BAVENCIO in combination with axitinib for the first-line treatment of adult patients with advanced renal cell carcinoma (RCC). In September 2017, the European Commission granted conditional marketing authorization for BAVENCIO as a monotherapy for the treatment of adult patients with metastatic Merkel cell carcinoma (MCC).
In the US, BAVENCIO in combination with axitinib is indicated for the first-line treatment of patients with advanced renal cell carcinoma (RCC). Additionally, the US Food and Drug Administration (FDA) granted accelerated approval for avelumab (BAVENCIO®) for the treatment of (i) adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (mMCC) and (ii) patients with locally advanced or metastatic urothelial carcinoma (mUC) who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications are approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.
BAVENCIO is currently approved for patients with MCC in 50 countries globally, with the majority of these approvals in a broad indication that is not limited to a specific line of treatment.
BAVENCIO Safety Profile from the EU Summary of Product Characteristics (SmPC)
The special warnings and precautions for use for BAVENCIO monotherapy include infusion-related reactions, as well as immune-related adverse reactions that include pneumonitis and hepatitis (including fatal cases), colitis, pancreatitis (including fatal cases), myocarditis (including fatal cases), endocrinopathies, nephritis and renal dysfunction, and other immune-related adverse reactions. The special warnings and precautions for use for BAVENCIO in combination with axitinib include hepatotoxicity.
The SmPC list of the most common adverse reactions with BAVENCIO monotherapy in patients with solid tumors includes fatigue, nausea, diarrhea, decreased appetite, constipation, infusion-related reactions, weight decreased and vomiting. The list of most common adverse reactions with BAVENCIO in combination with axitinib includes diarrhea, hypertension, fatigue, nausea, dysphonia, decreased appetite, hypothyroidism, cough, headache, dyspnea, and arthralgia.
About Merck-Pfizer Alliance
Immuno-oncology is a top priority for Merck and Pfizer. The global strategic alliance between Merck and Pfizer enables the companies to benefit from each other's strengths and capabilities and further explore the therapeutic potential of BAVENCIO, an anti-PD-L1 antibody initially discovered and developed by Merck. The immuno-oncology alliance is jointly developing and commercializing BAVENCIO. The alliance is focused on developing high-priority international clinical programs to investigate BAVENCIO as a monotherapy as well as combination regimens, and is striving to find new ways to treat cancer.
