About this study

The purpose of this randomized study is to determine the safety and efficacy of quaratusugene ozeplasmid (Reqorsa) added to osimertinib in NSCLC patients with activating EGFR mutations who have progressed while on treatment with osimertinib. Quaratusugene ozeplasmid consists of non-viral lipid nanoparticles that encapsulate a DNA plasmid with the TUSC2 tumor suppressor gene and is the first systemic gene therapy for cancer. The study is comprised of a Phase 1 dose escalation portion and two Phase 2 portions evaluating safety and efficacy. Enrollment in the Phase 1 dose escalation portion is complete and the recommended Phase 2 dose (RP2D) was determined. Phase 2a has initiated and enrolled patients are treated with quaratusugene ozeplasmid at the RP2D in combination with osimertinib. In Phase 2b, patients will be randomized to receive either quaratusugene ozeplasmid plus osimertinib or platinum-based chemotherapy.
