Quaratusugene Ozeplasmid (Reqorsa) in Combination With Pembrolizumab in Previously Treated Non-Small Lung Cancer (Acclaim-2)
A Phase 1/2 Open-Label, Dose-Escalation and Clinical Response Study of Quaratusugene Ozeplasmid in Combination With Pembrolizumab Versus Docetaxel With or Without Ramucirumab in Patients With Previously Treated Non-Small Cell Lung Cancer
The purpose of this study is to determine the safety and efficacy of quaratusugene ozeplasmid (Reqorsa), in combination with pembrolizumab in patients with previously treated NSCLC. Quaratusugene ozeplasmid consists of non-viral lipid nanoparticles that encapsulate a DNA plasmid with the TUSC2 tumor suppressor gene, and is a systemic gene therapy.
The study will be conducted in 2 phases, a dose escalation phase (Phase 1) and a safety and efficacy evaluation phase (Phase 2). In Phase 1, patients will be enrolled in sequential cohorts treated with successively higher doses of quaratusugene ozeplasmid in combination with pembrolizumab to determine the recommended Phase 2 dose (RP2D). Phase 2 will be comprised of a dose expansion portion and a randomized portion. In the dose expansion portion, patients will be enrolled and treated with quaratusugene ozeplasmid at the RP2D in combination with pembrolizumab. In the randomized portion, patients will be randomized to receive either the investigational treatment of quaratusugene ozeplasmid at the RP2D in combination with pembrolizumab or a control treatment of either docetaxel +/- ramucirumab or the investigator's treatment of choice.
Study Overview
Status
Conditions
Detailed Description
Acclaim-2 is a Phase 1/2 multicenter, open-label study of quaratusugene ozeplasmid in combination with pembrolizumab in patients with locally advanced or metastatic NSCLC with any PD-L1 TPS and NOT considered refractory to pembrolizumab, as defined by having achieved at least a 3-month clinical benefit to previous pembrolizumab-containing treatment.
The total duration of study for each patient will be dependent upon the safety, tolerability, and efficacy of the study treatment.
The Phase 1 portion of the study will involve a 3+3 dose escalation schema of quaratusugene ozeplasmid up to 0.12 mg/kg in combination with a fixed dose of pembrolizumab (200 mg) administered once via intravenous (IV) infusion during each 21-day treatment cycle. Three quaratusugene ozeplasmid doses will be tested (0.06, 0.09 and 0.12 mg/kg administered on Day 1 of a 21-day treatment cycle).
Phase 2 will involve a dose expansion portion and a randomized portion. In the dose expansion portion 36 patients will be enrolled to better characterize the safety and preliminary efficacy of quaratusugene in combination with pembrolizumab. Patients in the dose expansion portion will receive quaratusugene ozeplasmid at the RP2D determined in Phase 1 in combination with pembrolizumab once in every 21-day treatment cycle. When the PFS rate at 18 weeks has been evaluated for all patients in the dose expansion portion and been shown to meet the criteria for advancement to the randomized portion of Phase 2, the randomized portion of Phase 2 will be initiated. In the randomized portion of Phase 2, 126 patients will be randomized 2:1 to the investigational (quaratusugene ozeplasmid in combination with pembrolizumab) versus control (docetaxel with or without ramucirumab, or investigator's choice of treatment) treatment arms, respectively. Patients will be stratified by NSCLC histology (squamous versus nonsquamous predominant histology) for efficacy analysis purposes. The 84 patients randomized to the investigational arm will receive quaratusugene ozeplasmid, at the RP2D determined in Phase 1, administered in combination with 200 mg pembrolizumab once in every 21-day treatment cycle. The 42 patients randomized to the control arm may either receive docetaxel with or without ramucirumab, or a non-investigational treatment chosen by the investigator.
