Bristol-Myers Squibb’s Opdivo (nivolumab) + Yervoy (ipilimumab) Regimen Receives Expanded FDA Approval in Unresectable or Metastatic Melanoma Across BRAF Status

PRINCETON, N.J., January 23, 2016 --(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE:BMY) today announced that the U.S. Food and Drug Administration (FDA) has approved Opdivo (nivolumab) in combination with Yervoy (ipilimumab) for the treatment of patients with BRAF V600 wild-type and BRAF V600 mutation-positive unresectable or metastatic melanoma.1 This indication is approved under accelerated approval based on progression-free survival (PFS).1 Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.1 This approval expands the original indication for the Opdivo + Yervoy Regimen for the treatment of patients with BRAF V600 wild-type unresectable or metastatic melanoma to include patients, regardless of BRAF mutational status, based on data from the Phase 3 CheckMate -067 trial, in which PFS and overall survival (OS) were co-primary endpoints.1,2

Opdivo is associated with immune-mediated: pneumonitis, colitis, hepatitis, endocrinopathies, nephritis and renal dysfunction, rash, encephalitis, other adverse reactions; infusion reactions; and embryofetal toxicity.1 Please see the Important Safety Information section below, including Boxed WARNING for Yervoy regarding immune-mediated adverse reactions.

“For nearly a decade, our researchers have worked tirelessly to find treatment options that could improve outcomes for patients with late-stage melanoma, a particularly aggressive cancer, and we are incredibly proud of today’s approval to expand the use of the Opdivo + Yervoy Regimen to include patients with BRAF mutation-positive unresectable or metastatic melanoma. CheckMate -067 is the first Phase 3 study to observe the efficacy and safety of both Opdivo as a single-agent as well as in combination with Yervoy versus Yervoy alone,” said Chris Boerner, Head of U.S. Commercial, Bristol-Myers Squibb. “To make this treatment option available to more patients is truly a milestone in the fight against this deadly disease.”

The FDA also expanded the use of Opdivo as a single-agent to include previously untreated BRAF mutation-positive advanced melanoma patients.1 The use of Opdivo as a single-agent in patients with BRAF V600 mutation-positive unresectable or metastatic melanoma is approved under accelerated approval based on progression-free survival.1 Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.1 Opdivo was approved by the FDA in November 2015, for use in previously untreated patients with BRAF V600 wild-type unresectable or metastatic melanoma.1

“Patients with metastatic melanoma historically have a very challenging disease. Recent advances in our understanding of the immune response to cancer has yielded therapies which provide meaningful responses and hope. The combination of two Immuno-Oncology treatments, nivolumab and ipilimumab, has been shown to provide these patients with a much needed improvement in progression-free survival and response rates,” said Jedd D. Wolchok, MD, PhD, Chief, Melanoma and Immunotherapeutics Service, Department of Medicine and Ludwig Center at Memorial Sloan Kettering Cancer Center. “This expanded approval for the nivolumab and ipilimumab regimen provides more advanced melanoma patients with an Immuno-Oncology combination treatment, and the potential for improved outcomes.”

Expanded Approval Based on Efficacy Demonstrated in a Phase 3 Trial

CheckMate -067 is a Phase 3, double-blind, randomized study that evaluated the Opdivo + Yervoy Regimen or Opdivo monotherapy vs. Yervoy monotherapy in patients with previously untreated advanced melanoma.1, 2 The trial evaluated previously untreated patients, including both BRAF V600 mutant and wild-type advanced melanoma, and enrolled 945 patients who were randomized to receive the Opdivo + Yervoy Regimen (Opdivo 1 mg/kg plus Yervoy 3 mg/kg every 3 weeks for 4 doses followed by Opdivo 3 mg/kg every 2 weeks thereafter; n=314), Opdivo monotherapy (Opdivo 3 mg/kg every 2 weeks; n=316) or Yervoy monotherapy (Yervoy 3 mg/kg every 3 weeks for 4 doses followed by placebo every 2 weeks; n=315).1 Patients were treated until progression or unacceptable toxic effects.1 The median duration of exposure was 2.8 months (range: 1 day to 18.8 months) for patients in the Opdivo + Yervoy Regimen arm with a median of four doses (range: 1 to 39 for Opdivo; 1 to 4 for Yervoy), and 6.6 months (range: 1 day to 17.3 months) duration for the Opdivo monotherapy arm with a median of 15 doses (range: 1 to 38).1,2 The co-primary endpoints were PFS and OS; the study is ongoing and patients continue to be followed for OS.2

Results from the trial demonstrated a statistically significant improvement in PFS in patients with advanced melanoma treated with the Opdivo + Yervoy Regimen (p<0.0001) and with Opdivo as a single-agent (p<0.0001) vs. Yervoy monotherapy.1 Median PFS was 11.5 months (95% CI: 8.9-16.7) for the Opdivo + Yervoy Regimen and 6.9 months (95% CI: 4.3-9.5) for Opdivo monotherapy, vs. 2.9 months (95% CI: 2.8-3.4) for Yervoy monotherapy.1 The Opdivo + Yervoy Regimen demonstrated a 58% reduction in the risk of disease progression vs. Yervoy (HR: 0.42; 95% CI: 0.34-0.51; p<0.0001), while Opdivo monotherapy demonstrated a 43% risk reduction vs. Yervoy monotherapy (HR: 0.57; 95% CI: 0.47-0.69; p<0.0001).1

In addition, the Opdivo + Yervoy Regimen and Opdivo monotherapy demonstrated higher confirmed objective response rates (ORR; 50% and 40%; p<0.0001, respectively) vs. Yervoy monotherapy (14%).1 The percentage of patients with a complete response was 8.9%, 8.5% and 1.9%, favoring the Regimen and Opdivo monotherapy over Yervoy monotherapy.1 Partial responses were seen in 41% of patients treated with the Opdivo + Yervoy Regimen, 31% of patients treated with Opdivo monotherapy, and 12% of patients treated with Yervoy monotherapy. The Opdivo + Yervoy Regimen delivered durable responses, with three of four (76%) patients experiencing an ongoing response of at least six months (range: 1.2+ to 15.8+).1 Of patients in the Opdivo monotherapy and Yervoy monotherapy arms, 74% and 63% experienced an ongoing response of at least six months, respectively (ranges: 1.3+ to 14.6+; 1.0+ to 13.8+).1

“The melanoma community is excited to see the ongoing developments in research from the pharmaceutical industry, including Bristol-Myers Squibb, who made the first approved combination of two Immuno-Oncology treatments available to more patients fighting this disease,” said Tim Turnham, Executive Director, Melanoma Research Foundation. “Today’s expanded approvals continue to bring new treatment options to patients, and demonstrate the ongoing impact of Immuno-Oncology research.”

In CheckMate -067, serious adverse reactions (73% and 37%), adverse reactions leading to discontinuation (43% and 14%), or to dosing delays (55% and 28%), and Grade 3 or 4 adverse reactions (72% and 44%) all occurred more frequently in the Opdivo + Yervoy arm relative to the Opdivo arm.1 No overall differences in safety or efficacy were reported between elderly and younger patients.1 The most common adverse reactions leading to discontinuation of the Opdivo + Yervoy Regimen relative to Opdivo as a single-agent were diarrhea (8% and 1.9%), colitis (8% and 0.6%), increased ALT (4.8% and 1.3%), increased AST (4.5% and. 0.6%), and pneumonitis (1.9% and 0.3%).1 The most frequent (≥10%) serious adverse reactions in the Opdivo + Yervoy arm and the Opdivo arm, respectively, were diarrhea (13% and 2.6%), colitis (10% and 1.6%) and pyrexia (10% and 0.6%).1 The most common adverse reactions (≥20%) reported in patients receiving the Opdivo + Yervoy Regimen relative to Opdivo as a single-agent were fatigue (59% and 53%), rash (53% and 40%), diarrhea (52% and 31%), and nausea (40% and 28%).1 Pyrexia (37%), vomiting (28%) and dyspnea (20%) were also reported in ≥20% of patients receiving the Opdivo + Yervoy Regimen.1

About the Opdivo + Yervoy Regimen

The scientific rationale for targeting the immune system via dual immune checkpoint inhibition in cancer has formed the basis of a novel approach to the treatment of metastatic melanoma.2

Cancer cells may exploit “regulatory” pathways, such as checkpoint pathways, to hide from the immune system and shield the tumor from immune attack.2 Opdivo and Yervoy are immune checkpoint inhibitors that target separate, distinct and complementary checkpoint pathways (PD-1 and CTLA-4).1 The mechanism of action involves dual immune checkpoint inhibition resulting in increased anti-tumor activity.1 Yervoy blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, while Opdivo restores the active T-cell response directed at the tumor.1,3 This may affect healthy cells and result in immune-mediated adverse reactions, which can be severe and potentially fatal.1

Bristol-Myers Squibb has a broad, global development program to study the combination of Opdivo and Yervoy consisting of more than 14 trials in which more than 2,000 patients have been enrolled worldwide through September 2015.

About Opdivo

Cancer cells may exploit “regulatory” pathways, such as checkpoint pathways, to hide from the immune system and shield the tumor from immune attack.3 Opdivo’s broad global development program is based on Bristol-Myers Squibb’s understanding of the biology behind Immuno-Oncology. This scientific expertise serves as the basis for the Opdivo development program, which includes a broad range of Phase 3 clinical trials across a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 18,000 patients.

Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014, and currently has regulatory approval in 46 countries including the United States, Japan, and in the European Union.

About Metastatic Melanoma

Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin.3 Metastatic melanoma is the deadliest form of the disease, and occurs when cancer spreads beyond the surface of the skin to other organs.3The incidence of melanoma has been increasing for at least 30 years.3 Approximately 73,870 melanoma cases were estimated to be diagnosed in the U.S. in 2015.3 Melanoma is mostly curable when treated in its early stages.3 However, in its late stages, 5-year and 10-year survival rates in the U.S. average 15-20% and 10-15%, respectively.3
