A Study of Durvalumab and Stereotactic Radiotherapy for Stage I Non-Small Cell Lung Cancer

• Status: Not yet recruiting
• Trial end date: 2024-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The SCION Trial is a clinical trial in patients with early stage non-small cell lung cancer. The purpose of the trial is to investigate whether it is safe and effective to combine standard radiation treatment with a drug called durvalumab, a type of immunotherapy. In addition, the study will use a blood test to look for cancer cell DNA to determine how long treatment with durvalumab should last. Both the use of durvalumab and the use of the blood test are new strategies for managing early stage non-small cell lung cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

4. Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.]). The following are exceptions to this criterion:
