What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if a new combination of treatments outperforms the standard treatment for individuals with advanced non-small cell lung cancer (NSCLC). It compares the effectiveness of Sigvotatug Vedotin (an experimental treatment) combined with pembrolizumab against pembrolizumab alone. The study targets participants whose cancer cells exhibit high levels of PD-L1, a protein influencing immune response. Individuals with Stage 3 or 4 NSCLC and more than 50% PD-L1 in their cancer cells may qualify for this trial. Participants will receive pembrolizumab, and some will also receive Sigvotatug Vedotin, with regular clinic visits to monitor progress. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking cancer treatment.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on high-dose steroids or certain immune suppressants, you may need to adjust your treatment. It's best to discuss your specific medications with the study team.

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

Research shows that sigvotatug vedotin has promising results for treating non-small cell lung cancer (NSCLC). It has a manageable safety profile, meaning that while side effects exist, they are generally acceptable and controllable.

Patients have taken sigvotatug vedotin with pembrolizumab, another cancer treatment. Tests have shown that this combination is generally well-tolerated, meaning most people can handle the side effects. However, sigvotatug vedotin is still under study, so not all safety details are fully understood yet.

Pembrolizumab is already approved for other conditions, indicating a known safety record from previous studies and use. However, like any treatment, it can have side effects, which are carefully monitored during the trial.

Participants in the study will receive regular check-ups to ensure their safety and manage any side effects that may occur. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Sigvotatug Vedotin combined with Pembrolizumab for treating non-small cell lung cancer because it offers a fresh approach compared to standard treatments like chemotherapy or traditional immunotherapy. Sigvotatug Vedotin is unique because it's an antibody-drug conjugate, meaning it delivers a powerful anti-cancer drug directly into the cancer cells, reducing damage to healthy cells. Pairing this with Pembrolizumab, an already established immune checkpoint inhibitor, could enhance the immune system's ability to fight cancer more effectively. This combination could potentially improve outcomes for patients by targeting cancer cells more precisely and boosting the body's immune response.

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

This trial will compare the combination of Sigvotatug Vedotin with pembrolizumab to pembrolizumab monotherapy for treating non-small cell lung cancer (NSCLC). Studies have shown that using Sigvotatug Vedotin with pembrolizumab holds promise, with research indicating a confirmed overall response rate (ORR) of 42.9% in patients with high PD-L1 levels. Nearly half of these patients experienced cancer shrinkage or disappearance. Pembrolizumab alone is already effective for NSCLC, particularly in patients with high PD-L1. Adding Sigvotatug Vedotin, which targets a specific protein on cancer cells, may enhance the treatment's effectiveness. These early results suggest that this combination could be a strong option for managing advanced lung cancer. ^{1 3 5 6 7}

Published Research Related to This Trial

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.

Pembrolizumab, a monoclonal antibody targeting PD-1, has shown significant efficacy in treating advanced non-small-cell lung cancer (NSCLC) across multiple clinical trials, particularly in patients with PD-L1 expression levels of 1% or higher.

The KEYNOTE studies identified specific patient populations that benefit most from pembrolizumab, highlighting the importance of PD-L1 as a companion diagnostic, while future research will explore its role in earlier stages of cancer treatment and in combination therapies.

A 68-year-old patient with stage IV lung adenocarcinoma showed an unexpected positive response to paclitaxel after failing treatment with pembrolizumab, an anti-PD-1 immunotherapy.

The patient experienced a response duration of over fourteen months with paclitaxel, suggesting that combining or sequencing chemotherapy with immunotherapy may enhance treatment effectiveness in certain cases.

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 3 trial involving 305 patients with advanced non-small-cell lung cancer (NSCLC), pembrolizumab significantly improved quality of life (QOL) compared to chemotherapy, with a notable increase in the global health status score by 6.9 points versus a decrease of 0.9 points for chemotherapy.

Patients treated with pembrolizumab experienced a longer time to deterioration in symptoms like cough and chest pain, with 31% showing deterioration compared to 39% in the chemotherapy group, indicating that pembrolizumab may be a preferable first-line treatment for patients with PD-L1-positive NSCLC.

The study confirms that PD-1 inhibitors like Pembrolizumab and Nivolumab improve response and survival rates in advanced melanoma patients, especially when combined with the CTLA-4 inhibitor Ipilimumab, which shows superior efficacy compared to monotherapies.

However, these immunotherapies are associated with significant immune-related adverse events, some of which can be life-threatening, highlighting the need for further studies to better understand their safety profiles and mechanisms of action.

Pembrolizumab, an anti-PD-1 antibody, is effective as a first-line treatment for advanced nonsmall cell lung cancer (NSCLC) in patients with high PD-L1 expression (≥50%) and as a second-line option for those with lower PD-L1 expression (≥1%).

When combined with standard chemotherapy, pembrolizumab has demonstrated superior clinical outcomes compared to chemotherapy alone in patients with advanced NSCLC without targetable mutations, regardless of their PD-L1 expression levels.
