Trial Summary

What is the purpose of this trial?

This trial is testing a new drug called divarasib along with other cancer treatments. It focuses on people with advanced or metastatic non-small cell lung cancer. The study aims to see how divarasib moves through the body, its safety, and if it helps fight the cancer.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug pembrolizumab for non-small cell lung cancer?

Pembrolizumab has been shown to improve survival in patients with advanced non-small cell lung cancer, as it was approved by the FDA based on studies demonstrating significant improvements in survival compared to chemotherapy. ^{1 2 3 4 5}

Is the combination of Divarasib and Pembrolizumab safe for humans?

Pembrolizumab, one of the drugs in the combination, has been used in treating non-small cell lung cancer and is generally considered safe, but it can cause some immune-related side effects, like type 1 diabetes in rare cases. There is no specific safety data available for Divarasib in the provided research. ^{1 2 5 6 7}

What makes the drug combination of Divarasib and Pembrolizumab unique for treating non-small cell lung cancer?

The combination of Divarasib (GDC-6036) and Pembrolizumab is unique because it combines a novel investigational drug with an established immune checkpoint inhibitor, potentially enhancing the immune system's ability to fight non-small cell lung cancer by targeting different pathways. ^{1 2 3 8 9}

Treatment Details

Interventions

• GDC-6036 (Small Molecule Drug)
• Pembrolizumab (Monoclonal Antibodies)

Trial Overview The study tests Divarasib combined with other anti-cancer drugs: Pemetrexed, Cisplatin/Carboplatin and Pembrolizumab in patients who haven’t received any previous treatments for their NSCLC. It aims to assess how safe this combination is and how it affects the body (pharmacokinetics) as well as its effectiveness against the cancer.

Participant Groups

Group I: Cohort B - Combination Dose Finding + Dose Expansion Experimental Treatment 5 Interventions

Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) QD combined with pembrolizumab 200 mg IV Q3W plus investigator's choice of platinum-based chemotherapy (carboplatin or cisplatin) and pemetrexed.

Group II: Cohort A - Combination Dose Finding + Dose Expansion Experimental Treatment 2 Interventions

Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) once a day (QD) combined with pembrolizumab 200 mg intravenous (IV) infusion every 3 weeks (Q3W). During the expansion stage, some participants are planned to be randomized to one divarasib combination dose level; other participants are planned to be randomized to another divarasib combination dose level. Divarasib will be given in combination with pembrolizumab.

Findings from Research

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.

In a Phase 2 study involving 35 patients with non-small cell lung cancer, neoadjuvant pembrolizumab was found to be safe and well tolerated, with only one surgery delay due to thyroiditis and no mortality within 90 days post-surgery.

The study showed a high rate of R0 resection (88%) and a major pathologic response in 28% of patients, indicating that pembrolizumab may be more effective than standard neoadjuvant chemotherapy in this setting.

Pembrolizumab, a PD-1 inhibitor, has demonstrated clinical effectiveness in treating various solid tumors, particularly in patients with PD-L1-positive non-small-cell lung cancer and unresectable/metastatic melanoma.

Early-phase trials and ongoing studies are focused on further confirming the clinical benefits of pembrolizumab in thoracic malignancies, highlighting its potential as a significant treatment option in cancer therapy.

In a study involving 449 patients with advanced non-small-cell lung cancer (NSCLC), pembrolizumab showed overall response rates of 15% at 2 mg/kg, 25% at 10 mg/kg every 3 weeks, and 21% at 10 mg/kg every 2 weeks, indicating that the 2 mg/kg dose may be sufficient for efficacy.

The analysis revealed no significant relationship between the dose of pembrolizumab and its efficacy or safety, suggesting that the lower dose of 2 mg/kg every 3 weeks is effective and safe for patients with previously treated advanced NSCLC.

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, a PD-1 inhibitor used in cancer treatment, can lead to rare but serious immune-related adverse events, including type 1 diabetes mellitus, occurring in about 0.2% of cases.

A review of 42 cases revealed that patients may develop diabetic ketoacidosis during treatment, highlighting the need for blood glucose monitoring and awareness of this potential side effect among clinicians.

In a real-life study of 108 patients with advanced non-small cell lung cancer (NSCLC) and a PD-L1 tumor proportion score of ≥50%, pembrolizumab showed a median progression-free survival of 10.1 months, similar to results from the KEYNOTE-024 trial.

The treatment was generally well-tolerated, with only 8% of patients experiencing grade 3 adverse events, and no severe (grade 4 or 5) adverse events reported, indicating a favorable safety profile.

Pembrolizumab is a safe and effective immune checkpoint inhibitor that targets the PD-1 receptor, currently approved for treating advanced melanoma and metastatic non-small cell lung cancer (NSCLC).

Ongoing studies are exploring the potential of pembrolizumab in combination with other treatments for lung cancer and other cancer types, while also investigating biomarkers that may predict patient response to this therapy.

Pembrolizumab, a monoclonal antibody targeting PD-1, showed significant efficacy in treating a 79-year-old patient with advanced squamous cell lung cancer, leading to a complete response after just 3 cycles of treatment.

However, the patient developed acute myelomonocytic leukemia after starting pembrolizumab, highlighting a potential safety concern that warrants further investigation into the drug's effects on blood cell production.
