What is the purpose of this trial?

This trial explores treatments for individuals with stage IV non-squamous non-small cell lung cancer. It aims to determine whether starting treatment with the immunotherapy drug pembrolizumab alone is more effective than combining it with the chemotherapy drugs pemetrexed and carboplatin from the outset. Pembrolizumab enhances the immune system's ability to fight cancer, while pemetrexed and carboplatin inhibit cancer cell growth and spread. Suitable candidates for this trial have confirmed stage IV non-squamous non-small cell lung cancer with PD-L1 expression in their tumor cells. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants an opportunity to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot be on systemic steroid therapy or any other form of immunosuppressive therapy within 7 days before starting the trial treatment. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that the combination of pembrolizumab, pemetrexed, and carboplatin is generally well-tolerated for treating advanced non-squamous non-small cell lung cancer. Studies comparing this combination to chemotherapy alone found that patients responded better, and their cancer stopped growing for a longer period. This indicates that the treatment was more effective in controlling the cancer.

Regarding safety, previous studies found that adding pembrolizumab to chemotherapy did not cause unexpected side effects. Most patients experienced common side effects like tiredness, nausea, or loss of appetite, typical with chemotherapy. Importantly, serious side effects were not significantly more common in patients receiving pembrolizumab with chemotherapy compared to those receiving only chemotherapy.

For those considering this clinical trial, it is reassuring that this treatment has been used before with a manageable safety profile. Always discuss specific situations and any concerns with a doctor. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they combine pembrolizumab with chemotherapy agents like carboplatin and pemetrexed to target lung cancer. Pembrolizumab is an immunotherapy drug that enhances the body's immune response against cancer cells, offering a novel approach compared to traditional chemotherapy alone. Unlike current standard treatments, which primarily focus on directly killing cancer cells, pembrolizumab works by blocking a protein that prevents the immune system from attacking cancer cells. This combination aims to boost the effectiveness of chemotherapy by using the immune system as a partner in the fight against cancer. The potential for longer-lasting responses and improved survival rates makes this a promising option for patients with lung cancer.

What evidence suggests that this trial's treatments could be effective for non-small cell lung cancer?

Research has shown that using pembrolizumab with pemetrexed and carboplatin effectively treats advanced non-squamous non-small cell lung cancer. In this trial, participants will receive different treatment combinations involving these drugs. One study found that patients receiving this combination lived longer and experienced a longer period before their cancer worsened compared to those who received only chemotherapy. After five years, about 19.4% of patients treated with pembrolizumab and chemotherapy remained alive, indicating a lasting survival benefit. Pembrolizumab, an immunotherapy drug, helps the immune system attack cancer cells more effectively. Pemetrexed and carboplatin, chemotherapy drugs, stop cancer cells from growing. This combination has shown promising results in improving outcomes for lung cancer patients. ^{1 3 6 7 8}

In a study of 100 patients with non-small cell lung cancer (NSCLC) treated with pembrolizumab, further stratification of PD-L1 tumor proportion score (TPS) beyond 50% did not significantly affect progression-free survival (PFS).

Smoking status was associated with improved PFS, while prior radiotherapy was linked to decreased PFS, indicating that these factors, along with performance status, may serve as important biomarkers for predicting response to pembrolizumab treatment.

In a phase 2 study involving 216 patients with stage III non-small cell lung cancer (NSCLC), the combination of pembrolizumab and concurrent chemoradiation therapy (cCRT) showed a high objective response rate of approximately 70.5% in cohort A and 70.6% in cohort B, indicating strong antitumor activity.

The treatment was associated with manageable safety, with grade 3 or higher pneumonitis occurring in 8.0% of cohort A and 6.9% of cohort B, suggesting that while there are risks, the benefits of this treatment approach may outweigh them for patients with locally advanced NSCLC.
