Study Details
Study Description
Brief Summary
Monocentric study composed by 2 steps :
-
First step is a phase I with the aim of establish the recommended dose of mirdametinib administration (2 or 4 mg twice a day for 7 or 14 days per cycle for the 4 first of carboplatin/pemetrexed/pembrolizumab treatment)
-
Second step is a non comparative randomized (2:1) phase II trial testing the recommended dose of mirdametinib administration. The aim is the efficacy and safety of short course of mirdametinib treatment for the 4 first cycles of the carboplatin/pemetrexed/pembrolizumab treatment.

Phase 1/Phase 2 |
Detailed Description
- Phase I (15-24 patients) Using a classical "3+3 design": The phase I will included a maximum 24 patients. 3 patients will be included in dose level 1, if not DLT occurs 3 patients will be included in level 2. If 1 DLT occurs 3 additional patients will be included; if 2 or more DLT occurs the trial will be stopped. At level 2 if no DLT occurs RP2D 3 patients will be included at level 3; If 1 DLT occurs 3 additional patients will be included; if 2 or more DLT occurs RP2D will be level 1. Similar rules will be applied for level 3 and
- In absence of DLT CXCL10 and PD-L1, CD8 immune infiltrates and immunoscore IC (CD8-PDL1 dual markers) at baseline and 6 weeks, and clinical efficacy will be presented to IDMC for definition of RP2D. At the end of phase I inclusion toxicity, efficacy data and biological data (CXCL10 seric and IHC expression and PD-L1, CD8 immune infiltrates and immunoscore IC (CD8-PDL1 dual markers) at baseline and 6 weeks, PK and PK/PD data will be presented to IDMC to validate RP2D.
-
3 +/- 3 patients for level 1 (mirdametinib 4 mg twice/ 7 days)
-
3 +/- 3 patients for level 2 (mirdametinib 4 mg twice/ 14 days)
-
3 +/- 3 patients for level 3 (mirdametinib 6 mg twice/ 7 days)
-
3 +/- 3 patients for level 4 (mirdametinib 6 mg twice/ 14 days)
PHASE II (78 patients) Sample size calculation was performed using PASS v13. In keynote 189 response rate in PD-L1 <50% was 40% (28). A 3-month overall response rate (ORR) of 40% is considered unacceptable (P0=40%). The study team expect an ORR of 55% in the experiment arm (P1=55%, acceptable ORR).
Using a single stage design (A Hern, exact test) with unilateral α=10%, power=80%, 50 patients are needed for the primary endpoint analysis in the experimental arm. With 5% of non-evaluable patients, 52 patients will be included in this arm. With a 2:1 randomization the control arm will include 26 patients. A total of 78 subjects are then needed in the phase 2 part.

Outcome Measures
Primary Outcome Measures
- Safety will be evaluated using Dose Limiting Toxicities (DLT) [Until progression, an average of 10 months]
DLT is defined as any of the following toxicities occurring during the first 21 days after administration of the first dose. Adverse events (AEs) will be defined by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
