Trial Summary

What is the purpose of this trial?

The current study will compare pembrolizumab (MK-3475) plus maintenance olaparib, vs. pembrolizumab plus maintenance olaparib placebo for the treatment of squamous NSCLC. The study's 2 primary hypotheses are: 1. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance olaparib placebo with respect to progression-free survival (PFS) per RECIST 1.1 by blinded independent clinical review (BICR). 2. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance olaparib placebo with respect to overall survival (OS). As of Amendment 07, there will be no further analyses for OS and patient-reported outcome assessments.

Eligibility Criteria

This trial is for adults with Stage IV squamous non-small cell lung cancer (NSCLC) who haven't had previous systemic treatment. Participants must have a good performance status, meaning they're relatively active and can care for themselves. They need to provide a tumor tissue sample, have no other progressing cancers or severe health conditions like autoimmune diseases or infections such as HIV, and agree to use contraception.

Inclusion Criteria

I am fully active or restricted in physically strenuous activity but can do light work.
Have measurable disease based on RECIST 1.1
You are expected to live for at least three more months.

Treatment Details

Interventions

  • Carboplatin (Chemotherapy)
  • Nab-paclitaxel (Chemotherapy)
  • Olaparib (PARP Inhibitor)
  • Paclitaxel (Chemotherapy)
  • Pembrolizumab (Monoclonal Antibodies)
Trial OverviewThe study tests if adding olaparib after initial treatment with pembrolizumab improves progression-free survival (time without cancer worsening) and overall survival compared to using pembrolizumab with a placebo. Patients are randomly assigned to one of these two options.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Pembrolizumab + Carboplatin + Taxane + OlaparibExperimental Treatment5 Interventions
For the Induction Phase, participants receive 4 cycles: Pembrolizumab 200 mg, intravenous (IV) on Day 1 of each 21-day cycle PLUS carboplatin PLUS a taxane (either paclitaxel or nab-paclitaxel) for 4 cycles (21-day cycles). If the participant has a complete or partial response or stable disease to induction therapy, the participant is randomized to maintenance therapy. For the Maintenance Phase, participants receive pembrolizumab IV on Day 1 of each 21-day for up to 31 cycles PLUS maintenance oral olaparib 300 mg twice daily. In the Maintenance Phase, the participant continues to receive maintenance olaparib until centrally verified progressive disease, physician decision or intolerable toxicity.
Group II: Pembrolizumab + Carboplatin + Taxane + Olaparib PlaceboActive Control5 Interventions
For the Induction Phase, participants receive 4 cycles: Pembrolizumab 200 mg, intravenous (IV) on Day 1 of each 21-day cycle PLUS carboplatin PLUS a taxane (either paclitaxel or nab-paclitaxel) for 4 cycles (21-day cycles). If the participant has a complete or partial response or stable disease to induction therapy, the participant is randomized to maintenance therapy. For the Maintenance Phase, participants receive pembrolizumab IV on Day 1 of each 21-day for up to 31 cycles PLUS matching maintenance olaparib placebo twice daily. In the Maintenance Phase, the participant continues to receive maintenance olaparib placebo until centrally verified progressive disease, physician decision or intolerable toxicity.
