Testing the Timing of Pembrolizumab Alone or With Chemotherapy as First Line Treatment and Maintenance in Non-small Cell Lung Cancer

Official Title

EA5163/S1709 INSIGNA : A Randomized, Phase III Study of Firstline Immunotherapy Alone or in Combination With Chemotherapy in Induction/Maintenance or Postprogression in Advanced Nonsquamous Non-Small Cell Lung Cancer (NSCLC) With Immunobiomarker SIGNature-Driven Analysis

Summary:

This phase III trial studies whether pembrolizumab alone as a first-line treatment, followed by pemetrexed and carboplatin with or without pembrolizumab after disease progression is superior to induction with pembrolizumab, pemetrexed and carboplatin followed by pembrolizumab and pemetrexed maintenance in treating patients with stage IV non-squamous non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumour cells to grow and spread. Drugs used in chemotherapy, such as pemetrexed and carboplatin, work in different ways to stop the growth of tumour cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving first-line pembrolizumab followed by pemetrexed and carboplatin with or without pembrolizumab works better in treating patients with non-squamous non-small cell cancer.

Trial Description

Primary Outcome:

• Overall survival (OS)

Secondary Outcome:

• Progression-free survival (PFS)
• Best objective response
• Incidence of adverse events
• PD-L1 positivity

PRIMARY OBJECTIVE: I. To evaluate overall survival (OS) in each of the 2 experimental arms (Arms A and B) to control (Arm C). SECONDARY OBJECTIVES:
I. To evaluate progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 for Arm C versus each of Arms A and B. II. To evaluate best objective response rates per RECIST 1.1 for Arm C versus each of Arms A and B. III. To estimate toxicity within each of the treatment arms via the Common Terminology Criteria for Adverse Events (CTCAE) criteria. IV. To compare outcomes between Arms A and B. V. To compare outcomes by treatment arm within subgroups defined by a cutpoint of PD-L1 expression at >= 50%. BIOMARKER OBJECTIVE: I. To collect and bank tissue and blood for future research studies, including potential development of a prognostic and predictive signature for MK-3475 (pembrolizumab) in combination with chemotherapy versus MK-3475 (pembrolizumab) alone. OUTLINE:

Patients are randomized to 1 of 3 arms. ARM A: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Within 6 weeks of disease progression, patients receive pemetrexed IV over 10 minutes and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then may receive pemetrexed IV over 10 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. ARM B: Patients receive pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Within 6 weeks of disease progression, patients receive pembrolizumab IV over 30 minutes, pemetrexed IV over 10 minutes, and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive pembrolizumab IV over 30 minutes and pemetrexed IV over 10 minutes on day 1. Cycles repeat every 21 days for up to 2 years for pembrolizumab in the absence of disease progression or unacceptable toxicity and until to disease progression for pemetrexed. ARM C: Patients receive pembrolizumab IV over 30 minutes, pemetrexed IV over 10 minutes, and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive pembrolizumab IV over 30 minutes and pemetrexed IV over 10 minutes on day 1. Cycles repeat every 21 days for up to 2 years for pembrolizumab in the absence of disease progression or unacceptable toxicity and until to disease progression for pemetrexed. After completion of study treatment, patients are followed up for 5 years.
