About this study

Official title: 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.

Due to slow enrollment, the Accliam-2 trial was closed in Phase 1 and Phase 2 was not conducted.

Read the 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.

Due to slow enrollment, the Accliam-2 trial was closed in Phase 1 and Phase 2 was not conducted.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing quaratusugene ozeplasmid, pembrolizumab and docetaxel in people with Non Small Cell Lung Cancer, run by Genprex, Inc. at 6 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 27 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 3 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Enrollment was slow, due to competition with the many other clinical trials for the same patient population, which led to the decision to end enrollment in the trial.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recommended Phase 2 Dose (RP2D) - Phase 1 (time frame: First 21-days at each dose level). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2026.
