Quaratusugene Ozeplasmid (Reqorsa) and Osimertinib in Patients With Advanced Lung Cancer Who Progressed on Osimertinib

Acclaim-1 is an open-label, multi-center, Phase 1/2 study evaluating quaratusugene ozeplasmid (Reqorsa) plus osimertinib (investigational arm) versus platinum-based chemotherapy (control arm) in patients with advanced metastatic or recurrent NSCLC. Toxicities will be assessed by the Investigator using United States National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Serious Adverse Events and Dose Limiting Toxicities (DLT) will be reviewed by a Safety Review Committee. Phase 1 - Dose Escalation: The RP2D of quaratusugene ozeplasmid when given in combination with osimertinib has been identified. Phase 2a: This expansion cohort will be enrolled to better characterize safety, tolerability, and preliminary anti-tumor activity of the combination therapy. Phase 2b: Quaratusugene ozeplasmid in combination with osimertinib will be further evaluated using the RP2D identified in Phase 1. Patients may receive local therapy, such as radiation therapy, to progressing lesions prior to enrollment. Patients will be randomized to receive either the investigational arm or the control arm in a 1 to 1 ratio and stratified based on prior local radiotherapy.
