In Phase 1, Phase 2a and the investigational arm of Phase 2b, patients will receive their assigned dose of quaratusugene ozeplasmid (intravenous administration once every 21 days) plus osimertinib (80 mg fixed dose oral tablet taken daily starting on Day 1 through Day 21 of every 21-day treatment cycle) until disease progression or unacceptable toxicity.

In the control arm of Phase 2b, patients will receive platinum-based chemotherapy until disease progression or unacceptable toxicity.

Quaratusugene ozeplasmid is an experimental non-viral immunogene therapy utilizing the TUSC2 gene, designed to target cancer cells by interrupting cell signaling pathways that allow cancer cells to grow, reestablishing pathways that promote cancer cell death and modulating the immune response against cancer cells.

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 will comprise of a Phase 1 dose escalation and Phase 2 evaluations of safety and efficacy. In the Phase 1 dose escalation, patients will be enrolled in sequential cohorts treated with successively higher doses of quaratusugene ozeplasmid in combination with osimertinib. When the recommended Phase 2 dose (RP2D) is determined in Phase 1, Phase 2a will be initiated and patients will be enrolled in 2 parallel, non-randomized cohorts 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.

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 will be identified.

Phase 2a: Once the RP2D of quaratusugene ozeplasmid is identified in Phase 1, 2 expansion cohorts 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.

Phase 1: 3+3 dose escalation to identify RP2D.

Phase 2: RP2D further evaluated in Phase 2a followed by parallel randomization in a 1:1 ratio to either investigational arm or control arm.

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.

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.

Phase 1: 3+3 dose escalation to identify RP2D.

Phase 2: RP2D expansion cohort followed by parallel randomization in a 2:1 ratio to either investigational arm or control arm.

Up to 2 sequential dose selection cohorts will be treated with quaratusugene ozeplasmid (intravenous (IV) administration once every 21 days) plus atezolizumab (1200 mg IV administration once every 21 days) until disease progression or unacceptable toxicity.

Quaratusugene ozeplasmid doses will be evaluated (0.09 \[starting dose\], and 0.12 mg/kg) until the RP2D is identified.

Patients will be treated with the RP2D of quaratusugene ozeplasmid (IV administration once every 21 days) plus atezolizumab (1200 mg IV administration once every 21 days) until disease progression or unacceptable toxicity

Quaratusugene ozeplasmid is an experimental nonviral immunogene therapy utilizing the TUSC2 gene, designed to target cancer cells by interrupting cell signaling pathways that allow cancer cells to grow, reestablishing pathways that promote cancer cell death and modulating the immune response against cancer cells.

Atezolizumab is a monoclonal antibody that belongs to a class of drugs that binds to the programmed death-receptor 1 ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions.
