PRINCETON, N.J.--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE:BMY) today announced that the European Commission has approved Opdivo, a PD-1 immune checkpoint inhibitor, for the treatment of advanced (unresectable or metastatic) melanoma in adults, regardless of BRAF status. Today’s approval allows for the marketing of Opdivo in all 28 Member States of the EU. It follows an accelerated assessment by the Committee for Medicinal Products for Human Use (CHMP), which was announced on April 24, 2015. This accelerated assessment was given because Opdivo qualified for the designation as a “medicinal product of major interest from the point of view of public health and in particular from the view point of therapeutic innovation.” Opdivo is the only PD-1 immune checkpoint inhibitor to receive an accelerated assessment in Europe, and is the first approval given by the European Commission for a PD-1 inhibitor in any cancer.

The incidence of melanoma has continued to increase in almost all European countries, with an estimated one in five patients expected to develop metastatic, or advanced, disease. Historically, prognosis for late-stage metastatic melanoma has been poor: the average survival rate for stage IV is just six months with a one-year mortality rate of 75%.

“At Bristol-Myers Squibb, we are continually focused on developing new ways to transform the outlook for patients with some of the hardest-to-treat and deadliest cancers,” said Emmanuel Blin, senior vice president, head of commercialization, policy and operations, Bristol-Myers Squibb. “We are pleased to bring the first PD-1 immune checkpoint inhibitor to the European Union for the treatment of advanced melanoma. We are working relentlessly and at record-breaking speed to build upon our Immuno-Oncology science to deliver new treatment options, with the goal of improving long-term survival for patients.”

About CheckMate -066, -037

The European Commission’s approval is based on data from two Phase 3 studies (CheckMate -066, -037). Together, the trials investigated Opdivo across treatment lines and mutational status with a consistent dose of 3 mg/kg every two weeks that has been well-established across the Phase 3 clinical development program for Opdivo.

“The Phase 3 data supporting the approval of Opdivo demonstrates both superior overall survival and response rate for treatment-naïve patients with advanced melanoma, against the standard of care,” said Dirk Schadendorf, M.D., professor, director and chair, Clinic for Dermatology, University Hospital, Essen, Germany. “It is an important step forward in offering a new option for advanced melanoma patients in the European Union, especially considering that long-term benefits have largely been elusive in this treatment category.”

CheckMate -066 is a Phase 3 randomized, double-blind study comparing Opdivo (n=210) to the chemotherapy dacarbazine (DTIC) (n=208) in patients with treatment-naïve advanced melanoma. It is the first Phase 3 trial of a PD-1 immune checkpoint inhibitor to demonstrate superior overall survival (OS) in advanced melanoma, demonstrating a one-year survival rate of 73% for Opdivo versus 42% for DTIC, and there was a 58% decrease in the risk of death for patients treated with Opdivo based on a hazard ratio of 0.42 (99.79% CI, 0.25-0.73; P<0.0001). Objective response rate (ORR) also was significantly higher for Opdivo than DTIC (40% vs. 14%, P<0.0001). The primary endpoint of this trial was OS. Secondary endpoints included progression-free survival (PFS) and ORR by RECIST v1.1 criteria.

Safety was reported in all patients treated in the Opdivo and DTIC arms. Fewer discontinuations were observed with Opdivo than DTIC (6.8% vs. 11.7%) as well as for treatment-related Grade 3/4 adverse events (AEs) (11.7% vs. 17.6%), which were managed using established safety algorithms. The most common Opdivo treatment-related AEs were fatigue (20%), pruritus (17%), and nausea (16.5%). Common adverse events in the DTIC arm were consistent with those in previous reports and included nausea (41.5%), vomiting (21%), fatigue (15%), diarrhea (15%) and hematological toxicities. No deaths were attributed to study drug toxicity in either arm.

CheckMate -037 is a Phase 3 randomized, controlled open-label study of Opdivo (n=272) versus investigator’s choice chemotherapy (ICC) (n=133) -- either single-agent dacarbazine or carboplatin plus paclitaxel -- in patients with advanced melanoma who were previously treated with Yervoy (ipilimumab), and, if BRAF mutation positive, a BRAF inhibitor. Co-primary endpoints of the study are ORR and OS. In a planned interim analysis of ORR, an improvement in ORR of 32% was seen in the Opdivo arm (95% CI, 23.5%-40.8%) versus 11% in the investigator’s choice chemotherapy arm (95% CI, 3.5%-23.1%). A majority of responses (87%) were ongoing in those patients administered Opdivo. Responses to Opdivo were demonstrated in both patients with or without BRAF mutuation and regardless of PD-L1 expression.

Safety was reported on all patients treated in the Opdivo (n=268) and ICC (n=102) arms. The majority of Opdivo treatment-related adverse events (AEs) were Grade 1/2 and managed using recommended treatment algorithms. Grade 3/4 drug-related AEs were less frequent for the Opdivo arm (9% vs. 31% of patients treated with chemotherapy). Discontinuations due to drug-related AEs of any grade occurred in 3% of Opdivo-treated patients and 7% of patients administered ICC. There were no deaths related to study drug toxicity.

The approval also was based on data from a Phase 1b study (Study -003) in relapsed advanced or metastatic melanoma, which demonstrated the first characterization of Opdivo benefit/risk in advanced melanoma. Of the 306 previously-treated patients enrolled in the study, 107 had melanoma and received Opdivo at a dose of 0.1 mg/kg, 0.3 mg/kg, 1 mg/kg, 3 mg/kg, or 10 mg/kg every two weeks for a maximum of two years. In this patient population, objective response was reported in 33 patients (31%) with a median duration of response of 22.9 months (95% CI: 17.0, NR). The median PFS was 3.7 months (95% CI: 1.9, 9.3). The median OS was 17.3 months (95% CI: 12.5, 36.7), and the estimated OS rates were 63% (95% CI: 53, 71) at one year, 48% (95% CI: 38, 57) at two years, and 41% (95% CI: 31, 51) at three years.

About Opdivo

Bristol-Myers Squibb has a broad, global development program to study Opdivo in multiple tumor types consisting of more than 50 trials – as monotherapy or in combination with other therapies – in which more than 8,000 patients have been enrolled worldwide.

Opdivo became the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world on July 4, 2014 when Ono Pharmaceutical Co. announced that it received manufacturing and marketing approval in Japan for the treatment of patients with unresectable melanoma. On December 22, 2014, the U.S. Food and Drug Administration (FDA) granted its first approval for Opdivo for the treatment of patients with unresectable or metastatic melanoma and disease progression following Yervoy (ipilimumab) and, if BRAF V600 mutation positive, a BRAF inhibitor. On March 4, 2015, Opdivo received its second FDA approval for the treatment of patients with metastatic squamous non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy.

About Advanced Melanoma

Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin. Metastatic melanoma is the deadliest form of the disease, and occurs when cancer spreads beyond the surface of the skin to the other organs, such as the lymph nodes, lungs, brain or other areas of the body. Melanoma is the ninth most common cancer in Europe, with an estimated 100,000 new cases diagnosed annually and more than 20,000 deaths.

Immuno-Oncology at Bristol-Myers Squibb

Surgery, radiation, cytotoxic or targeted therapies have represented the mainstay of cancer treatment over the last several decades, but long-term survival and a positive quality of life have remained elusive for many patients with advanced disease.

To address this unmet medical need, Bristol-Myers Squibb is leading research in an innovative field of cancer research and treatment known as Immuno-Oncology, which involves agents whose primary mechanism is to work directly with the body’s immune system to fight cancer. The company is exploring a variety of compounds and immunotherapeutic approaches for patients with different types of cancer, including researching the potential of combining Immuno-Oncology agents that target different pathways in the treatment of cancer.

Bristol-Myers Squibb is committed to advancing the science of Immuno-Oncology, with the goal of changing survival expectations and the way patients live with cancer.
