PRINCETON, NJ, & SAN FRANCISCO, CA, USA I March 14, 2022 I Bristol Myers Squibb (NYSE: BMY) and Nektar Therapeutics (NASDAQ: NKTR) today announced an update following the first analysis of the Phase 3 PIVOT IO-001 study evaluating the doublet therapy of bempegaldesleukin in combination with Opdivo (nivolumab) compared to Opdivo monotherapy as a first-line treatment for previously untreated unresectable or metastatic melanoma. Following a review of the study for efficacy and safety by an independent Data Monitoring Committee (DMC), Bristol Myers Squibb and Nektar were informed that the study did not meet the primary endpoints of progression-free survival (PFS) and objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR). The DMC notified the companies that the third primary endpoint of overall survival (OS) did not meet statistical significance at the first interim analysis.

Given there was no additional clinical benefit in the doublet therapy arm compared to the monotherapy arm for the primary endpoints of PFS and ORR, and based on the data reviewed by the DMC, the companies have decided to unblind the trial and to perform no additional analyses for the OS endpoint. Additionally, based on the results from PIVOT IO-001, the companies have also made the decision to discontinue enrollment and unblind the ongoing PIVOT-12 study in adjuvant melanoma, which is evaluating the doublet therapy of bempegaldesleukin in combination with Opdivo compared to Opdivo monotherapy in patients at high risk for recurrence after complete resection of melanoma. Patients in both studies will be counseled on their treatment options, and permitted to continue treatment if agreed to with their physician.

The companies will review the data and plan to share the results with the scientific community.

“As a leader in developing innovative therapies for patients with cancer, we have continued to explore novel strategies that may expand treatment benefits to more patients with advanced disease,” said Jonathan Cheng, senior vice president and head of oncology development, Bristol Myers Squibb. “We are disappointed with the results of this trial, which we had hoped would lead to a new therapeutic option to treat metastatic melanoma. We express our gratitude to the patients, caregivers and investigators who chose to participate in these trials.”

The other four studies ongoing for bempegaldesleukin plus Opdivo in renal cell carcinoma and bladder cancer are continuing.

“While we are surprised and deeply disappointed in these results for the melanoma study, we will continue to await initial results from our first two ongoing studies in renal cell carcinoma and urothelial cancer, which are currently expected in the first half of 2022,” said Jonathan Zalevsky, chief research and development officer of Nektar Therapeutics. “We look forward to collaborating with BMS to evaluate the data from these other studies to guide the future development of bempegaldesleukin. Nektar remains dedicated to the development of therapeutics to treat cancer and auto-immune disease.”

About PIVOT IO-001

PIVOT IO-001 is a randomized Phase 3 study evaluating the combination of bempegaldesleukin in combination with Opdivo versus Opdivo alone in patients with previously untreated unresectable or metastatic melanoma. The study is sponsored and conducted by Bristol-Myers Squibb. A total of 783 patients were randomized 1:1 to receive a combination of bempegaldesleukin 0.006 mg/kg and Opdivo 360 mg or Opdivo 360 mg by intravenous infusion every three weeks in an outpatient setting. Patients were treated until disease recurrence, unacceptable toxicity or withdrawal of consent for up to 24 months.

About PIVOT-12

PIVOT-12 is a randomized Phase 3 open-label study evaluating the adjuvant immunotherapy of bempegaldesleukin combined with Opdivo versus Opdivo alone after complete resection of melanoma in patients at high risk for recurrence. The study is sponsored and conducted by Nektar Therapeutics.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol Myers Squibb’s scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.
