Not intended for US, Canada and UK-based media
-- EU approval based on JAVELIN Renal 101 trial results demonstrating significant improvement in progression-free survival with BAVENCIO in combination with axitinib compared with sunitinib
-- Combination regimen approved across all IMDC prognostic risk groups and irrespective of PD-L1 expression
DARMSTADT, Germany, and NEW YORK, Oct. 29, 2019 /PRNewswire/ -- Merck and Pfizer Inc. (NYSE: PFE) today announced that the European Commission (EC) has approved BAVENCIO® (avelumab) in combination with axitinib for the first-line treatment of adult patients with advanced renal cell carcinoma (RCC). The approval was based on positive interim results from the Phase III JAVELIN Renal 101 study, which demonstrated that BAVENCIO in combination with axitinib significantly lowered risk of disease progression or death by 31% (HR: 0.69 [95% CI: 0.574-0.825; p<0.0001]) and nearly doubled objective response rate (ORR; 52.5% [95% CI: 47.7-57.2] vs. 27.3% [95% CI: 23.2-31.6]) compared with sunitinib in patients with advanced RCC regardless of PD-L1 status. The study included patients across International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic risk groups. Improvement in progression-free survival (PFS) was observed across pre-specified subgroups in patients receiving the treatment combination.1 Merck and Pfizer have a global strategic alliance to jointly develop and commercialize BAVENCIO.
"There is a high incidence of kidney cancer in Europe, and for the most common type, renal cell carcinoma, we continue to need additional treatment options, particularly for patients with advanced disease, where outcomes are poorest," said Professor James Larkin, Consultant Medical Oncologist at The Royal Marsden NHS Foundation Trust and Professor at the Institute of Cancer Research (ICR). "We've seen a demonstrated efficacy benefit and safety and tolerability profile for avelumab in combination with axitinib across all prognostic risk groups in patients with advanced renal cell carcinoma, so today's approval in Europe brings an important option that can help healthcare professionals optimize treatment strategies across risk stratification."
In 2018, an estimated 136,500 new cases of kidney cancer were diagnosed in Europe, and approximately 54,700 people died from the disease.2 Many patients living with advanced RCC do not go on to receive additional treatment after first-line therapy,3,4 for reasons that may include poor performance status or adverse events from their initial treatment.3,5,6 The five-year survival rate for patients with advanced RCC is approximately 12%.7
"This first European approval of an anti-PD-L1 as part of a combination treatment for advanced renal cell carcinoma builds on our commitment to bringing innovative treatment options to patients with hard-to-treat cancers through our extensive JAVELIN clinical trial program," said Rehan Verjee, Global Head of Innovative Medicine Franchises for the Biopharma business of Merck. "RCC is the most common form of kidney cancer, accounting for 90% of diagnoses. We are now working to make BAVENCIO in combination with axitinib available for patients with advanced renal cell carcinoma as quickly as possible."
"The European Commission approval of BAVENCIO in combination with axitinib has the potential to bring even more patients with advanced renal cell carcinoma a new first-line treatment, and it allows us to continue to deliver on our more than decade-long passion to do more for patients with kidney cancer," said Andy Schmeltz, Global President, Pfizer Oncology. "We thank all of the researchers, doctors, advocates, patients and their families who helped get us here today, and we will continue in our fight against this advanced cancer."
The EC's decision follows the U.S. Food and Drug Administration (FDA) approval of BAVENCIO in combination with axitinib for the first-line treatment of patients with advanced RCC in May 2019. A supplemental application for BAVENCIO in combination with axitinib in unresectable or metastatic RCC was submitted in Japan in January 2019.
Additionally, with this approval, the posology section of the Summary of Product Characteristics for BAVENCIO has been updated. The recommended dose of BAVENCIO as monotherapy is 800 mg administered intravenously over 60 minutes every 2 weeks. Administration of BAVENCIO should continue according to the recommended schedule until disease progression or unacceptable toxicity. The recommended dose of BAVENCIO in combination with axitinib is 800 mg administered intravenously over 60 minutes every 2 weeks and axitinib 5 mg orally taken twice daily (12 hours apart) with or without food until disease progression or unacceptable toxicity.1
Data from JAVELIN Renal 101 Study Supporting Approval
This approval was based on interim data from the Phase III JAVELIN Renal 101 study, a randomized, multicenter, open-label study of BAVENCIO in combination with axitinib in 886 patients with untreated advanced or metastatic RCC with a clear cell component. The study included patients across risk groups (International Metastatic Renal Cell Carcinoma Database Consortium [IMDC]: 21% favorable, 62% intermediate and 16% poor; Memorial Sloan Kettering Cancer Center [MSKCC]: 22% favorable, 65% intermediate and 11% poor). The primary efficacy endpoints were progression-free survival (PFS) as assessed by a Blinded Independent Central Review (BICR) using RECIST v1.1 and overall survival (OS) in the first-line treatment of patients with advanced RCC who have PD-L1-positive tumors (PD‑L1 expression level >1%). PFS based on BICR assessment per RECIST v1.1 and OS irrespective of PD‑L1 expression, objective response (OR), time to response (TTR), duration of response (DOR) and safety are included as secondary endpoints. The study is continuing for OS.
In the analysis, BAVENCIO in combination with axitinib significantly improved median PFS compared with sunitinib by more than five months in patients irrespective of PD-L1 expression (13.3 months [95% CI: 11.1–15.3] vs. 8.0 months [95% CI: 6.7–9.8]). With a median follow-up for OS of 19 months, data for the trial's other endpoint of OS were immature, with 27% of deaths, and the trial is continuing as planned. The hazard ratio for OS in patients treated with BAVENCIO in combination with axitinib compared with sunitinib was 0.80 (95% CI: 0.616, 1.027) at the interim analysis.
The most common adverse reactions were diarrhea (62.8%), hypertension (49.3%), fatigue (42.9%), nausea (33.5%), dysphonia (32.7%), decreased appetite (26.0%), hypothyroidism (25.2%), cough (23.7%), headache (21.3%), dyspnea (20.9%), and arthralgia (20.9%).
About the JAVELIN Clinical Development Program
The clinical development program for avelumab, known as JAVELIN, involves at least 30 clinical programs and more than 10,000 patients evaluated across more than 15 different tumor types. In addition to RCC, these tumor types include gastric/gastro-esophageal junction cancer, head and neck cancer, Merkel cell carcinoma, non-small cell lung cancer and urothelial carcinoma.
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.
