Study of Binimetinib in Combination With Pembrolizumab in Advanced Non-Small Cell Lung Cancer

NCT ID: NCT03991819

Last Updated: 2025-12-05

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE1
• Total Enrollment: 40 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-09-20
• Study Completion Date: 2026-12-31

Brief Summary

This is a Phase I/Ib study whose purpose is to find out if combining an experimental drug called binimetinib with pembrolizumab is beneficial in people who have advanced non-small cell lung cancer. This study may also see if the combination is safe and may also find the best dose of binimetinib that should be added to pembrolizumab.

Detailed Description

This study will have two parts:

Phase I - During this part, also called the dose de-escalation part, an initial group of 6 participants will receive a certain planned dose of binimetinib in addition to a standard dose of pembrolizumab. If this combination is found to be safe during the first 28 days of receiving the study drugs, this will be considered the most appropriate dose of the study drug combination (the highest dose of binimetinib that can be given with pembrolizumab without causing serious side effects).

Phase Ib - Once the appropriate dose of binimetinib is confirmed in Phase I (as described above), additional participants will be enrolled in the Phase Ib to further test how safe, tolerable, and effective the study drugs at that dose level. Phase Ib will also evaluate the anti-tumour activity of binimetinib and pembrolizumab in participants with advanced non-small cell lung cancer.

Study Groups

Phase 1

Cycle 1 = 28 days and Cycle 2 and Future Cycles = 21 days

Binimetinib, by mouth (orally): Level 1: 45 mg, twice a day, continuously; Level -1: 30 mg, twice a day, continuously; Level -2: 30 mg, twice a day, for Days 1-14 of each cycle only

Pembrolizumab, by vein (intravenously), at a dose of 200 mg on Day 8 of Cycle 1, then Day 1 of Cycle 2 and future cycles.

Group Type: EXPERIMENTAL

Pembrolizumab

Intervention Type: DRUG

Pembrolizumab is an immunotherapy drug that is approved by Health Canada for the treatment of patients with PD-L1 positive non-small cell lung cancer as a first treatment. PD-1 is a type of protein that binds to another type of protein known as PD-L1. When these proteins bind together, it helps prevent cells from killing each other, including cancer cells. Some drugs, like pembrolizumab, are used to block PD-1 from binding to PD-L1. When the protein is blocked, the body's immune system can kill more cells.

Binimetinib

Intervention Type: DRUG

Binimetinib is a drug that, inside the cell, blocks an important series of chemical reactions called a molecular pathway. Binimetinib blocks the MEK1/2 pathway from working. In some types of cancers, this pathway becomes too active, which can cause tumor cell growth. Blocking the MEK1/2 pathway from working is thought to slow or stop tumor cell growth.

Phase 1b

All Cycles = 21 days

Binimetinib, by mouth (orally), at the best dose found in Phase 1 of the study, twice a day, continuously.

Pembrolizumab, by vein (intravenously), at a dose of 200 mg on Day 1 of every cycle.

Eligibility Criteria

Inclusion Criteria

• Histologically confirmed diagnosis of non-small cell lung carcinoma with tumour PDL-1 TPS≥50% by 22C3 pharmDx immunohistochemistry. Patients must have EGFR wild-type, ALK-rearrangement negative metastatic or advanced NSCLC (stage IV or incurable stage III). Patients with neuroendocrine (carcinoid) carcinoma, small cell or mixed small cell and non-small cell carcinoma are not eligible.

• The participant provides written informed consent for the trial.
• Have measurable disease.
• Provide archival tumor tissue sample for KRAS/BRAF/STK11 mutation analysis or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated.
• Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
• Have a life expectancy of greater than 3 months.
