Trial Summary

What is the purpose of this trial?

This phase II trial tests the safety and side effects of durvalumab and grid therapy in treating patients with non-small cell lung cancer who have progressed during or within 6 months of durvalumab administration for non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy sources to kill tumor cells and shrink tumors. Spatially fractionated radiation therapy or "grid therapy" is a technique which delivers high doses of radiation to small areas of the tumor which can lead to more concentrated tumor cell killing and causes less damage to normal tissue. Giving grid therapy with durvalumab may help durvalumab work better to kill tumor cells in patients with non-small cell lung cancer.

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 use immunosuppressive medications within 14 days before starting durvalumab, except for certain low-dose or local steroids. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment Durvalumab + Radiation for Non-Small Cell Lung Cancer?

Research shows that using durvalumab after chemoradiotherapy significantly improves survival in patients with stage III non-small cell lung cancer. The PACIFIC trial demonstrated that durvalumab helps patients live longer and delays the progression of the disease. ^{1 2 3 4 5}

Is the combination of Durvalumab and radiation therapy safe for humans?

Durvalumab, also known as Imfinzi or MEDI4736, has shown a manageable safety profile in treating various cancers, including non-small cell lung cancer, when used alone or with other treatments like radiation. Some patients may experience side effects, but overall, it is considered to have acceptable tolerability. ^{4 6 7 8 9}

What makes the drug Durvalumab unique for treating non-small cell lung cancer?

Durvalumab is unique because it is used after radiotherapy for patients with non-small cell lung cancer who cannot undergo chemotherapy, offering a potential survival benefit compared to radiotherapy alone. It works by blocking a protein called PD-L1, which helps the immune system attack cancer cells more effectively. ^{2 10 11 12 13}

Findings from Research

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.

Durvalumab for the treatment of non-small cell lung cancer. Mezquita, L., Planchard, D.[2019]

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.
