What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if a new immunotherapy combination is effective and safe for treating a specific type of lung cancer called NSCLC, which is advanced and inoperable. Participants will receive either a combination of two immunotherapy drugs, durvalumab and domvanalimab, or durvalumab with a placebo. This study targets individuals whose lung cancer has not progressed after previous chemotherapy and radiation treatments. Participants should have lung cancer that hasn't advanced beyond a certain stage and must have undergone specific prior treatments. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants the 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, but you cannot use immunosuppressive medication within 14 days before starting the trial.

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

Research has shown that durvalumab, a drug used in many cancer treatments, is generally safe. When combined with tremelimumab, it has a tolerable safety profile and has produced positive results for patients with solid tumors. So far, patients have managed side effects well.

The evidence for domvanalimab is less clear when used alone. It remains under study, but the current trial offers hope for its safety when combined with durvalumab.

This study is in an advanced phase, indicating some evidence already supports the safety of these treatments for further testing. However, it is important to remember that all medicines can have risks and side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of domvanalimab and durvalumab for treating lung cancer because it offers a new approach compared to existing options. Unlike standard treatments that typically target cancer cells directly, this combo enhances the immune system's ability to fight cancer by blocking inhibitory signals that prevent immune cells from attacking tumors. Domvanalimab is an innovative component, as it targets the TIGIT pathway, which is relatively new in cancer immunotherapy. This mechanism could potentially lead to more effective and durable responses in patients, setting it apart from current therapies.

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

Research has shown that combining durvalumab and domvanalimab, which participants in this trial may receive, may help treat non-small cell lung cancer (NSCLC). Studies have found that durvalumab, when used with other treatments, greatly improves survival rates for people with NSCLC. Early results suggest that adding domvanalimab might enhance this effect. These treatments help the immune system fight cancer cells more effectively. While more research is needed, the early findings are promising for those considering this treatment option. ^{1 6 7 8 9}

Published Research Related to This Trial

In a phase I study involving 58 patients with advanced solid tumors, the combination of MEDI0562 with either durvalumab or tremelimumab showed moderate toxicity, with 74.1% and 67.7% of patients reporting treatment-related adverse events, respectively.

While three patients showed a partial response to the MEDI0562 and durvalumab combination, the study did not demonstrate clear efficacy signals, indicating that further research is needed to evaluate the effectiveness of these combinations.

Durvalumab, a PD-L1 blocking antibody, has shown clinical efficacy and a manageable safety profile in treating advanced non-small-cell lung cancer, especially in patients with ≥25% PD-L1 expression.

The drug is being evaluated in various treatment settings, including as a monotherapy and in combination with other therapies, showing promising results particularly after chemoradiation, although lower response rates were noted in patients with EGFR and ALK mutations.

Durvalumab is an FDA-approved monoclonal antibody that enhances T-cell responses against cancer by blocking the PD-L1 pathway, specifically for patients with advanced urothelial carcinoma who have progressed after platinum-based chemotherapy.

The drug is currently being tested in phase III trials for various cancers, including lung and head and neck cancers, indicating its potential broad application in oncology beyond urothelial carcinoma.

Durvalumab: First Global Approval. Syed, YY.[2022]

Durvalumab, a PD-L1 inhibitor, has been shown to be safe for patients with various solid tumors, with common side effects including pruritus and fatigue, based on a meta-analysis of 17 studies involving 1,529 patients.

Higher levels of PD-L1 expression in tumors are linked to better treatment responses to durvalumab, indicating that PD-L1 could serve as a useful biomarker for predicting the drug's efficacy.

Patients with metastatic non-small-cell lung cancer who developed immune-mediated adverse events (imAEs) while treated with durvalumab showed significantly improved overall survival compared to those without imAEs, indicating a potential link between imAE development and treatment efficacy.

A predictive model was created using machine learning to identify patients at higher risk of developing imAEs, which could help tailor treatment strategies and enhance patient outcomes in immunotherapy.

In the phase 3 POSEIDON study involving 1013 treatment-naïve patients with metastatic non-small-cell lung cancer (NSCLC), the combination of tremelimumab, durvalumab, and chemotherapy significantly improved overall survival and progression-free survival compared to chemotherapy alone.

Patients receiving the combination treatment also experienced a longer time to deterioration in quality of life and various symptoms, indicating better overall health status compared to those on chemotherapy, supporting its use as a first-line treatment option.

In a phase 1b study involving 102 patients with advanced non-small cell lung cancer, the combination of durvalumab and tremelimumab demonstrated manageable safety, although 36% of patients experienced serious treatment-related adverse events, including three treatment-related deaths.

The treatment showed evidence of antitumor activity in both PD-L1-positive and PD-L1-negative tumors, with a confirmed objective response rate of 23% in the cohort receiving tremelimumab 1 mg/kg, indicating potential effectiveness regardless of PD-L1 status.

In a pooled analysis of 1332 patients with advanced non-small-cell lung cancer (NSCLC), the combination of nivolumab and ipilimumab showed a median overall survival (OS) of 18.6 months and a 3-year OS rate of 35%, indicating significant long-term survival benefits compared to traditional chemotherapy.

The study found that patients who responded to treatment at 6 months had markedly better survival rates, with a 3-year OS of 66% for responders, highlighting the importance of early response in predicting long-term outcomes.

In a phase II trial involving 116 patients with squamous non-small-cell lung cancer, durvalumab demonstrated a 16% overall response rate and a disease control rate of 54%, indicating its potential effectiveness as a treatment after platinum-based chemotherapy.

The treatment was associated with a median overall survival of 11.6 months and a median progression-free survival of 2.9 months, with 32% of patients experiencing grade ≥ 3 treatment-related adverse events, suggesting that while durvalumab is active, it also carries a risk of significant side effects.
