A Study of BIO 300 and Thoracic Radiation Therapy to Lower Pneumonitis in Patients with Non-Small Cell Lung Cancer and Interstitial Lung Disease

Trial Status: active

This phase II trial studies whether giving BIO 300 with thoracic radiation therapy works to lower a type of lung inflammation (pneumonitis) in patients with non-small cell lung cancer (NSCLC) and interstitial lung disease (ILD). ILD is another type of lung inflammation that causes scarring and stiffness in the lungs, leading to difficulty breathing and lung damage. About 10% of people with NSCLC also have ILD. People with NSCLC and ILD can sometimes be limited in their treatment options because surgery and certain medications are not recommended for people with ILD. People with NSCLC and ILD can receive thoracic radiation therapy-high-energy radiation that targets and destroys cancer cells in the chest area. However, this therapy can cause lung-related side effects, including pneumonitis, another type of lung inflammation with symptoms that include coughing, difficulty breathing, shortness of breath, and chest pain. The main ingredient in BIO 300 is genistein, which is found in soy. Genistein works as an estrogen receptor beta (ERβ) agonist. This means it attaches to and activates ERβ, a protein found in the body, including inside the lungs. When genistein activates ERβ, it can help control inflammation, slow down cell growth, and protect lung tissue from damage. BIO 300 may be an effective way to lower pneumonitis in patients with NSCLC and ILD.
