What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new lung cancer treatment, tobemstomig (an experimental treatment), combined with chemotherapy. The goal is to determine if this combination is more effective than the current standard treatment, pembrolizumab with chemotherapy, for individuals with advanced non-small-cell lung cancer (NSCLC) that cannot be surgically removed. Participants must have untreated, advanced NSCLC and be ineligible for surgery or combined chemotherapy and radiation. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial requires that you stop taking any anti-cancer therapy, including hormonal therapy, at least 21 days before starting the study treatment. Additionally, you must not be on systemic immunosuppressive medication within 2 weeks prior to starting the study treatment.

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

Research shows that tobemstomig, a new treatment under study, has generally been well-tolerated in early research. These initial studies focused on determining the right dose and assessing its safety for people with solid tumors. While no major safety issues emerged, more information is needed to fully understand its safety.

In contrast, pembrolizumab, which is being compared in the trial, has a proven track record. It has been used to treat lung cancer for several years. Research has shown it is generally safe when combined with chemotherapy and has been linked to a 5-year survival benefit in patients with non-small-cell lung cancer (NSCLC).

Since this trial is in an early phase, tobemstomig is still undergoing safety testing. However, pembrolizumab is already known to be safe in similar situations. These findings can help prospective participants understand the safety of both treatments being studied. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard of care for lung cancer, which often includes drugs like pembrolizumab paired with chemotherapy, Tobemstomig represents a new approach. Researchers are excited about Tobemstomig because it is an innovative treatment option that combines a novel active ingredient with chemotherapy. This combination could potentially enhance the effectiveness of the treatment by targeting cancer cells in a unique way. By introducing this new mechanism of action, Tobemstomig aims to improve outcomes for patients with non-squamous and squamous non-small cell lung cancer (NSCLC).

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

This trial will compare two treatment options for non-small-cell lung cancer (NSCLC): pembrolizumab combined with chemotherapy and tobemstomig combined with chemotherapy. Research has shown that combining pembrolizumab with chemotherapy can extend the lives of patients with NSCLC. Specifically, studies found that patients lived for a median of 19.2 months, and about 25% were still alive five years after starting treatment.

For tobemstomig, a newer treatment option in this trial, early trials are examining its ability to help the immune system find and attack cancer cells. Tobemstomig targets two proteins, PD-1 and LAG-3, which usually help cancer hide from the immune system. Initial results are promising, suggesting that tobemstomig might enhance the immune response against cancer, but more research is needed to confirm its effectiveness. ^{6 7 8 9 10}

Participants with SQ NSCLC will receive blinded pembrolizumab in combination with paclitaxel and carboplatin, all on Day 1 Q3W for four 21-day cycles, followed by blinded pembrolizumab (on Day 1) Q3W until disease progression or treatment discontinuation.

Published Research Related to This Trial

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 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 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.

In patients with metastatic non-small-cell lung cancer (NSCLC) expressing PD-L1 in ≥50% of tumor cells, pembrolizumab significantly improves progression-free and overall survival compared to traditional platinum-based chemotherapy.

Combining pembrolizumab with standard chemotherapy (pemetrexed and a platinum drug) enhances survival outcomes regardless of PD-L1 expression, indicating a broader efficacy of this combination therapy.

In a study of 24 patients with advanced non-small cell lung cancer (NSCLC) treated with pembrolizumab, the objective response rate was 45.8%, indicating that nearly half of the patients experienced a reduction in tumor size after treatment.

Pembrolizumab showed promising results even in PD-L1-negative patients, with a major pathological response of 75% and a pathological complete response of 50% in those who underwent surgery, suggesting its potential effectiveness across different patient profiles.

In a real-life study of 121 patients with advanced non-squamous non-small cell lung cancer, the combination of pembrolizumab and chemotherapy resulted in a median progression-free survival of 9 months and overall survival of 20.6 months, demonstrating its efficacy as a first-line treatment.

The treatment was generally well-tolerated, with manageable side effects; however, 17.5% of patients experienced grade 3-4 adverse events, and there were two treatment-related deaths, indicating the need for careful monitoring during therapy.
