What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new drug called MK-1084, alone or with other treatments, in patients with advanced cancers that have a specific mutation. The drug aims to block this mutation to stop or slow down the cancer. Another drug, Sotorasib, was the first approved treatment for this type of cancer.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are in Arm 4, you must be able to interrupt aspirin or other NSAIDs for a few days around the administration of pemetrexed.

Is the combination of MK-1084 and Pembrolizumab safe for humans?

Pembrolizumab, also known as Keytruda, has been used in various cancer treatments and is generally considered safe, but it can cause side effects like fatigue, cough, and nausea. Serious side effects, such as pneumonitis (lung inflammation), occur in a small percentage of patients. Always discuss potential risks with your healthcare provider. ^{1 2 3 4 5}

What makes the drug MK-1084 + Pembrolizumab unique for treating solid cancers?

The combination of MK-1084 and Pembrolizumab is unique because it involves using Pembrolizumab, a PD-1 inhibitor that helps the immune system attack cancer cells, alongside MK-1084, which may have a different mechanism of action. This combination could potentially enhance the effectiveness of the immune response against solid tumors compared to using Pembrolizumab alone. ^{1 2 3 4 6}

What data supports the effectiveness of the drug pembrolizumab in treating solid cancers?

Pembrolizumab has shown effectiveness in treating various solid tumors, including non-small cell lung cancer and melanoma, by improving survival rates and showing high response rates with minimal side effects. ^{1 2 4 6 7}

• Pembrolizumab

Trial Overview The study tests MK-1084 alone and combined with Pembrolizumab in patients with KRAS G12C mutant tumors. It aims to assess the effectiveness and safety of these treatments in different groups: some untreated NSCLC cases; others who've had systemic therapy; and various stages of colorectal cancer after previous therapies failed.

How Is the Trial Designed?

Group I: Arm 6 Experimental Treatment 5 Interventions

Participants will receive MK-1084 daily oral dose. Additionally, participants receive an intravenous infusion of cetuximab (per label) every 2 weeks of each 28-day cycle, oxaliplatin (per label) for first 6 cycles, and leucovorin (per label) and 5-fluorouracil (per label) once every 14-days.

Group II: Arm 5 Experimental Treatment 2 Interventions

Participants will receive MK-1084 daily oral dose plus an intravenous infusion of cetuximab (per label) every 2 weeks of each 28-day cycle.

Group III: Arm 4 Experimental Treatment 4 Interventions

Participants will receive MK-1084 daily oral dose plus an intravenous infusion of pembrolizumab (200 mg) once every 21-day cycle for up to 35 cycles (up to \~24 months). Participants will also receive carboplatin (per label) and pemetrexed (per label) once every 21-day cycle for the first 4 cycles.

Group IV: Arm 3 Experimental Treatment 1 Intervention

Participants will receive alternate formulation of MK-1084 until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Group V: Arm 2 Experimental Treatment 2 Interventions

Participants will receive MK-1084 daily oral escalating dose of up to 800 mg plus pembrolizumab given as a 200 mg intravenous infusion once every 21-day cycle up to a total of 35 cycles (up to \~24 months). Treatment with MK-1084 will continue until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Group VI: Arm 1 Experimental Treatment 1 Intervention

Participants will receive daily oral escalating doses of up to 800 mg of MK-1084 until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Published Research Related to This Trial

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

Pembrolizumab (Keytruda) was approved by the FDA for treating metastatic non-small cell lung cancer (mNSCLC) in patients with tumors expressing PD-L1, showing significant improvements in overall survival (OS) and progression-free survival (PFS) in two major clinical trials with thousands of participants.

In the KEYNOTE-024 trial, pembrolizumab demonstrated a 40% reduction in the risk of death compared to chemotherapy, while in the KEYNOTE-010 trial, it also showed a significant survival advantage over chemotherapy in patients who had previously progressed on treatment.

Pembrolizumab, an immune checkpoint inhibitor, can cause pneumonitis in 1%-5% of patients, and this case report highlights an atypical presentation of this side effect in a patient with metastatic squamous cell carcinoma.

The patient was successfully treated with steroid therapy after ruling out other potential causes, leading to complete resolution of the pneumonitis, emphasizing the importance of recognizing and managing atypical cases of checkpoint inhibitor-pneumonitis.

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating advanced melanoma, showing an overall response rate of 24% in a trial of 89 patients, with 86% of responses lasting at least 6 months.

While there are potential immune-mediated side effects, the benefits of prolonged tumor response durations were deemed to outweigh these risks, marking an improvement over existing treatments.
