Innovent Biologics, Inc. and Eli Lilly and Company today jointly announced that the U.S. Food and Drug Administration (FDA) accepted for review a Biologics License Application (BLA) for sintilimab injection in combination with pemetrexed and platinum chemotherapy for the first-line treatment of people with nonsquamous non-small cell lung cancer (NSCLC). This is the first U.S. regulatory submission of sintilimab, a PD-1 inhibitor being developed and commercialized under a global collaboration agreement between Innovent and Lilly.
"The acceptance of this application – the first for sintilimab in the U.S. and outside of China – is an important milestone in Innovent's global commercialization strategy and in our collaboration with Lilly," said Dr. Yongjun Liu, president of Innovent. "We look forward to working closely with the FDA to potentially bring this sintilimab-pemetrexed-platinum chemotherapy combination as a treatment option in the U.S., following the regimen's regulatory approval in China earlier this year."
Sintilimab is currently being evaluated in a wide variety of cancer types under a broad clinical development program. To date, sintilimab has two indications approved in China, three regulatory submissions under review in China, and this regulatory application under review in U.S.. This regulatory application was submitted to the FDA in March 2021, primarily based on the results of the Phase 3 ORIENT-11 trial. The Prescription Drug User Fee Act (PDUFA) goal date for the FDA to make a decision on the sintilimab application is in March 2022. The FDA stated that it did not identify any potential review issues in its acceptance letter. It is currently planning to hold an Advisory Committee meeting to discuss this application.
"We are pleased the sintilimab submission is progressing. Our pursuit of this proposed indication in the U.S. reinforces Lilly's and Innovent's joint commitment to offer additional therapeutic options for people living with lung cancer and the healthcare providers who treat them," said Anne White, president, Lilly Oncology. "This is an encouraging start for our collaborative efforts to make sintilimab available in countries beyond China, as we continue to pursue opportunities globally for this immuno-oncology medicine across various tumor types."
About the ORIENT-11 Trial
ORIENT-11 is a randomized, double-blind, Phase 3 clinical trial assessing the efficacy and safety of sintilimab in combination with pemetrexed and platinum chemotherapy compared to placebo in combination with pemetrexed and platinum chemotherapy as a first-line treatment for patients with advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC), with no sensitizing EGFR mutations or ALK rearrangements. The primary endpoint is progression-free survival (PFS) as assessed by Independent Radiographic Review Committee (IRRC) based on RECIST v1.1., and secondary endpoints include overall survival (OS) and safety profile.
A total of 397 patients were enrolled and randomized 2:1 to receive either sintilimab 200mg or placebo in combination with pemetrexed and platinum chemotherapy every three weeks for up to four cycles, followed by either sintilimab or placebo plus pemetrexed maintenance therapy. Patients received treatment until radiographic disease progression, unacceptable toxicity or any other conditions that required treatment discontinuation. Conditional crossover was permitted. The results of the ORIENT-11 study were published in 2020.1
