PRINCETON, NJ and SAN FRANCISCO, CA, USA I April 14, 2022 INektar Therapeutics (NASDAQ: NKTR) and Bristol Myers Squibb (NYSE: BMY) today announced that based on results from pre-planned analyses of two late-stage clinical studies of bempegaldesleukin (BEMPEG) in combination with Opdivo (nivolumab) in renal cell carcinoma (RCC) and bladder cancer, the companies have jointly decided to end the global clinical development program for bempegaldesleukin in combination with Opdivo. These studies and all other ongoing studies in the program will be discontinued.

In the Phase 3 PIVOT-09 study in patients with previously untreated advanced or metastatic RCC, Nektar and Bristol Myers Squibb were informed by an independent Data Monitoring Committee (DMC) that a final analysis of objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) showed that bempegaldesleukin in combination with Opdivo did not meet the prespecified boundary for statistical significance in comparison to the tyrosine kinase inhibitor (TKI) control arm in the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) intermediate/poor-risk or all-risk populations. An interim analysis of overall survival (OS) also did not meet the prespecified boundary for statistical significance in either of these populations. Given there was no clinical benefit in the doublet therapy arm compared to the TKI arm, the companies have decided to unblind the trial and to perform no additional analyses for the OS endpoint.

In the separate Phase 2 PIVOT-10 study of the bempegaldesleukin/Opdivo doublet in patients with cisplatin-ineligible, locally advanced or metastatic urothelial cancer, a final ORR analysis assessed by BICR showed that bempegaldesleukin in combination with Opdivo did not reach an efficacy threshold to support continuing the program in urothelial carcinoma.    

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

All other studies of bempegaldesleukin in combination with Opdivo, including a pivotal study in muscle-invasive bladder cancer (CA045-009), a Phase 1/2 study of the doublet in combination with TKI therapy in 1L RCC (CA045-011) and a Phase 1/2 study in recurrent and/or refractory pediatric tumors (CA045-020), will be discontinued, allowing patients and their physicians to consider standard of care treatment options for their specific conditions. 

“As a leader in developing innovative therapies for patients with cancer, we are committed to continuing to explore novel combinations and pathways and advancing research that may help cancer patients achieve better outcomes,” said Jonathan Cheng, senior vice president and head of oncology development, Bristol Myers Squibb. “We are immensely grateful to the patients and investigators who participated in these studies.”

The companies previously announced in March that two pivotal studies in melanoma would be discontinued based on results in the Phase 3 PIVOT IO-001 study in metastatic melanoma. Over the coming months, the companies will work jointly to discontinue the clinical program for bempegaldesleukin in combination with Opdivo.

“We thank BMS for their collaboration on the studies of bempegaldesleukin. Nektar remains dedicated to the development of therapeutics to treat cancer and auto-immune disease,” said Jonathan Zalevsky, chief research and development officer of Nektar Therapeutics.

About PIVOT-09
PIVOT-09 is a global, randomized Phase 3 study evaluating bempegaldesleukin combined with Opdivo versus investigator’s choice of a tyrosine kinase inhibitor (TKI) therapy (either sunitinib or cabozantinib) in patients with previously untreated advanced renal cell carcinoma in the IMDC all-risk and the IMDC intermediate- or poor-risk categories. A total of 623 patients were randomized 1:1 to receive a combination of bempegaldesleukin 0.006 mg/kg and Opdivo 360 mg every three weeks in an outpatient setting by intravenous infusion or a specified dose of TKI therapy. Patients were treated until disease recurrence, unacceptable toxicity or withdrawal of consent for up to 24 months. The study is sponsored and conducted by Nektar Therapeutics.

About PIVOT-10
PIVOT-10 is a global Phase 2 single-arm study evaluating bempegaldesleukin combined with Opdivo in patients deemed ineligible for cisplatin therapy including those whose baseline tumor cells express low levels of PD-L1. A total of 192 patients were enrolled and patients were treated until disease recurrence, unacceptable toxicity or withdrawal of consent for up to 24 months. The study is sponsored and conducted by Nektar Therapeutics.

About Renal Cell Carcinoma
Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, accounting for more than 431,000 new cases and 179,000 deaths worldwide each year.  RCC is approximately twice as common in men as in women, with the highest rates of the disease in North America and Europe.  The five-year survival rate for those diagnosed with metastatic, or advanced, kidney cancer is 13.9%.

About Urothelial Carcinoma
Bladder cancer is the 10th most common cancer in the world, with more than 573,000 new cases diagnosed annually. Urothelial carcinoma, which most frequently begins in the cells that line the inside of the bladder, accounts for approximately 90% of bladder cancer cases. In addition to the bladder, urothelial carcinoma can occur in other parts of the urinary tract, including the ureters and renal pelvis. The majority of urothelial carcinomas are diagnosed at an early stage, but rates of recurrence are high. Approximately 50% of patients who undergo surgery for muscle-invasive disease will experience disease recurrence. Additionally, approximately 20% to 25% of patients with urothelial carcinoma develop metastatic disease. For patients with metastatic cancer, the prognosis is poor, with a median overall survival of approximately 12 to 14 months when treated with systemic therapy. The poor durability of responses in the first-line setting presents a major challenge in the treatment of metastatic disease, and there are limited treatment options in the second-line setting for patients with advanced urothelial carcinoma.

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.

About the Bristol Myers Squibb and Ono Pharmaceutical Collaboration
In 2011, through a collaboration agreement with Ono Pharmaceutical Co., Bristol Myers Squibb expanded its territorial rights to develop and commercialize Opdivo globally, except in Japan, South Korea and Taiwan, where Ono had retained all rights to the compound at the time. On July 23, 2014, Ono and Bristol Myers Squibb further expanded the companies’ strategic collaboration agreement to jointly develop and commercialize multiple immunotherapies – as single agents and combination regimens – for patients with cancer in Japan, South Korea and Taiwan.
