Regeneron Provides Updates on Phase 3 Libtayo(R) (cemiplimab) Development Program in Advanced Non-small Cell Lung CancerTARRYTOWN, N.Y., Nov. 5, 2019 -- (Healthcare Sales & Marketing Network) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today provided an update on the ongoing Phase 3 development program evaluating Libtayo® (cemiplimab), a PD-1 inhibitor, as monotherapy and combination therapy in first-line patients with advanced non-small cell lung cancer (NSCLC). Regeneron is currently recruiting patients in two Phase 3 trials in first-line NSCLC.
The first trial, an open-label randomized trial that compares Libtayo monotherapy to standard-of-care platinum-based chemotherapy in patients with high PD-L1 expression (tumor proportion score [TPS] >50%):
- The trial has enrolled 90% of the 700 planned patients and is expected to be fully enrolled by year's end.
- The independent data monitoring committee recently conducted an interim analysis for overall survival (OS) based on approximately 34% of anticipated events and recommended the trial should continue as planned. The next event-driven interim analysis for OS is anticipated in 2020.
- In the first 361 randomized patients (minimum 6 months of follow-up), the confirmed objective response rate (ORR), as determined by investigators, is currently 42% for Libtayo patients and 22% for patients treated with chemotherapy.
- Part 1 is fully enrolled (n=323), and evaluates patients with PD-L1 expression of <50% in three treatment groups: chemotherapy, chemotherapy with Libtayo, and chemotherapy in combination with Libtayo and ipilimumab.
- Part 2, a randomized, double-blind, placebo-controlled Phase 3 trial (n=450), has enrolled approximately 20% of patients, and is expected to complete enrollment in the second half of 2020. The trial evaluates patients with all PD-L1 expression levels in two treatment groups: chemotherapy alone or chemotherapy in combination with Libtayo.
About the Phase 3 Libtayo NSCLC Trials
The primary endpoints of the randomized, open-label Phase 3 monotherapy trial are OS and progression-free survival (PFS). Patients receive either Libtayo 350 mg every 3 weeks or investigator's choice of a standard-of-care platinum-based doublet chemotherapy regimen (with or without maintenance therapy). Patients in the trial have stage IIIB, IIIC or stage IV squamous or non-squamous NSCLC, are not candidates for definitive chemotherapy and radiation, have not received prior systemic treatment for their advanced disease, and have high PD-L1 expression (TPS ³50%). As part of a separate internal research effort assessing the effect of baseline patient variables, an unintended aggregation of open-label ORR data by treatment group occurred for the first 361 enrolled patients. In NSCLC, regulatory authorities do not consider ORR a validated surrogate endpoint.
In the Phase 3 combination trial, the Part 1 primary endpoint is ORR and the Part 2 primary endpoints are OS and PFS. Patients in the Libtayo treatment groups receive 350 mg every 3 weeks. Trial patients have either stage IIIB or IIIC squamous or non-squamous NSCLC and are not candidates for treatment with definitive concurrent chemoradiation, or have stage IV disease and have not received prior systemic treatment for recurrent or metastatic NSCLC.
Libtayo is a fully-human monoclonal antibody targeting the immune checkpoint receptor PD-1 (programmed cell death protein-1). It is approved in the U.S., European Union, Canada and Brazil for adult patients with metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not candidates for curative surgery or curative radiation. In the U.S., the generic name for Libtayo is cemiplimab-rwlc, with rwlc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration.
In addition to NSCLC, Libtayo is also being investigated in potential registrational trials in basal cell carcinoma and cervical cancer, along with additional trials in squamous cell carcinoma of the head and neck, melanoma, colorectal cancer, prostate cancer, multiple myeloma, Hodgkin lymphoma and non-Hodgkin lymphoma. These trials are designed to investigate Libtayo as monotherapy; in combination with conventional treatments like chemotherapy; or in combination with other investigational agents, including vaccines, oncolytic viruses and bispecific antibodies, among others. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.
IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS
What is the most important information I should know about Libtayo? Libtayo is a medicine that may treat a type of skin cancer by working with your immune system.
