Multicenter Phase 1b/2a Clinical Trial of Radioprotectant BIO 300 Oral Suspension for Patients With Non-Small Cell Lung Cancer Receiving Concurrent Chemoradiotherapy.

Purpose: Radiation therapy is part of the standard treatment regimen for non-small cell lung cancer (NSCLC). Although radiation therapy is an effective tool to manage NSCLC, it can be associated with significant dose-limiting toxicities. These toxicities can lead to treatment interruption or early termination and worsening clinical outcomes in addition to reductions in patient quality of life.

Proton Reirradiation: Expert Recommendations for Reducing Toxicities and Offering New Chances of Cure in Patients With Challenging Recurrence Malignancies.

Local and regional recurrences are common following an initial course of radiotherapy, yet management of these recurrences remains a challenge. Reirradiation may be an optimal treatment approach for providing durable tumor control and even offering select patients with locoregional recurrences or new primary tumors a chance of cure, but photon reirradiation can be associated with considerable risks of high grade acute and late toxicities. The high conformality and lack of exit dose with proton therapy offer significant advantages for reirradiation.

Combining Immunotherapy with Radiation Therapy in Non-Small Cell Lung Cancer.

Immune checkpoint inhibitors have recently been demonstrated to improve survival in metastatic and locally advanced non-small cell lung cancer (NSCLC). Radiation therapy has a well-established role in the treatment of NSCLC and has more recently been shown to be immunostimulatory, with the potential to enhance the efficacy of immunotherapy. This comprehensive review details the current roles of radiation therapy and immune checkpoint inhibitors in NSCLC, discusses the intersection of these two modalities and their potential to have combined synergistic responses, and highlights existing preclinical and clinical data and ongoing clinical trials of combined immunotherapy and radiotherapy across all NSCLC stages.
