What is the purpose of this trial?

This trial tests the effectiveness and safety of combining durvalumab, a cancer-fighting drug, with either oleclumab or monalizumab to treat a specific type of lung cancer that cannot be removed by surgery. It targets individuals with non-small cell lung cancer (NSCLC) who have undergone chemotherapy and radiation without cancer progression. Participants will receive one of three treatments: durvalumab with oleclumab, durvalumab with monalizumab, or durvalumab with a placebo (a substance with no therapeutic effect). Eligible individuals must have completed chemotherapy and radiation treatment without further disease progression. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial requires that you stop using immunosuppressive medications (drugs that lower the body's ability to fight infections) within 14 days before starting the study treatment. Other medications are not specifically mentioned, so it's best to discuss your current medications with the trial team.

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

Research has shown that durvalumab is generally safe for patients with various solid cancers. When combined with tremelimumab, it is well-tolerated and can improve patient outcomes. Oleclumab, sometimes used with durvalumab, has been tested in patients with advanced colorectal cancer and is considered safe.

Studies suggest that monalizumab is safe when used with durvalumab and chemotherapy for treating small cell lung cancer. This combination has been tested in clinical settings with a focus on safety.

Both combinations—durvalumab with oleclumab and durvalumab with monalizumab—have been part of several studies to ensure they do not cause severe side effects in most patients. These findings support the safety of these treatments for further testing in clinical trials like the one under consideration. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the treatments involving Durvalumab combined with Oleclumab and Monalizumab for lung cancer because they offer novel approaches to enhancing the body's immune response against cancer cells. Most treatments for lung cancer, like chemotherapy and radiotherapy, directly attack cancer cells, but these can also damage healthy cells. Durvalumab works differently by blocking a protein called PD-L1, which helps immune cells recognize and attack cancer cells more effectively. Oleclumab targets another protein, CD73, potentially increasing the anti-tumor activity by reducing immune suppression in the tumor environment. Meanwhile, Monalizumab blocks NKG2A, a receptor that can inhibit immune cells, thus unleashing a more robust immune attack on cancer cells. These mechanisms offer a promising new approach to treating lung cancer by harnessing and directing the body's natural defenses.

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

In this trial, participants will receive different treatment combinations to assess their effectiveness for non-small cell lung cancer (NSCLC). Previous studies have shown promising results when combining durvalumab with either oleclumab or monalizumab. Specifically, the combination of durvalumab and oleclumab achieved a progression-free survival (PFS) rate of 64.8% after 10 months, indicating patients lived longer without cancer worsening. Meanwhile, the combination of durvalumab and monalizumab achieved an even higher PFS rate of 72.7%. These combinations proved more effective than durvalumab alone, which had a PFS rate of 39.2%. Durvalumab is known to help stop cancer from growing or spreading after chemotherapy and radiation. These findings suggest that adding oleclumab or monalizumab to durvalumab may improve outcomes for patients with this type of lung cancer. ^{1 6 7 8 9}

Published Research Related to This Trial

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.

Safety and efficacy of durvalumab (MEDI4736) in various solid tumors. Yang, H., Shen, K., Zhu, C., et al.[2022]

The combination of durvalumab and tremelimumab in cancer treatment is associated with a higher incidence of severe adverse events (32.6%) compared to durvalumab alone (23.8%), indicating increased safety concerns with the combination therapy.

Patients receiving the combination therapy also experienced higher rates of specific side effects such as diarrhea (15.6% vs. 8.1%), rash (11.1% vs. 6.5%), and treatment discontinuation (18% vs. 3%), highlighting the need for careful monitoring and patient counseling regarding these risks.

Adverse Events and Tolerability of Combined Durvalumab and Tremelimumab versus Durvalumab Alone in Solid Cancers: A Systematic Review and Meta-Analysis. Fahmy, O., Ahmed, OAA., Khairul-Asri, MG., et al.[2023]

In the phase III PACIFIC trial, durvalumab significantly improved overall survival (OS) and progression-free survival (PFS) in patients with unresectable stage III non-small-cell lung cancer after chemoradiotherapy, with a 5-year OS rate of 42.9% compared to 33.4% for placebo.

The updated analyses, with a median follow-up of 34.2 months, showed that durvalumab continues to provide durable benefits, establishing a new standard of care for this patient population.

In a phase II study involving 189 patients with unresectable stage III non-small-cell lung cancer, combining durvalumab with either oleclumab or monalizumab significantly improved the overall response rate (ORR) and progression-free survival (PFS) compared to durvalumab alone.

The safety profile of the combination therapies was similar to durvalumab alone, with no new significant safety concerns, indicating that these combinations could be promising options for further investigation in larger trials.

In a study of 83 patients with unresectable stage III non-small cell lung cancer (NSCLC) receiving durvalumab, 25.3% experienced pneumonitis, confirming the risk associated with this treatment.

The incidence of pneumonitis observed in this real-world setting aligns with findings from the PACIFIC trial, indicating that the safety profile of durvalumab is consistent in clinical practice.

Real-World Incidence of Pneumonitis in Patients Receiving Durvalumab. LeClair, JN., Merl, MY., Cohenuram, M., et al.[2022]

In the phase III PACIFIC trial, durvalumab treatment led to a low incidence of immune-mediated adverse events (imAEs), with any-grade immune-mediated pneumonitis occurring in 9.4% of patients and grade 3/4 imAEs in only 3.4%.

Despite the occurrence of imAEs being more common with durvalumab compared to placebo, these events were generally manageable with treatments like corticosteroids, indicating that the benefits of the PACIFIC regimen outweigh the risks.

Characterizing immune-mediated adverse events with durvalumab in patients with unresectable stage III NSCLC: A post-hoc analysis of the PACIFIC trial. Naidoo, J., Vansteenkiste, JF., Faivre-Finn, C., et al.[2022]

In a study of 121 patients with stage III non-small cell lung cancer treated with durvalumab, those with over 50% PD-L1 expression had significantly better outcomes, with a 1-year survival rate of 97% compared to 73% and 78% for lower expression groups.

Higher PD-L1 expression (>50%) was strongly associated with improved progression-free survival and overall survival, indicating that PD-L1 levels could be a key factor in predicting the effectiveness of durvalumab treatment.
