Lung Cancer Clinical Trial

Reqorsa (Quaratusugene Ozeplasmid) in Combination With Pembrolizumab in Previously Treated Non-Small Lung Cancer

Summary

The purpose of this randomized study is to determine the safety and efficacy of Reqorsa (quaratusugene ozeplasmid, formerly known as GPX-001), in combination with pembrolizumab in patients with previously treated NSCLC. Reqorsa consists of non-viral lipid nanoparticles that encapsulate a DNA plasmid with the TUSC2 tumor suppressor gene, and is the first systemic gene therapy.

The study will be conducted in 2 phases, a dose escalation and expansion 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 Reqorsa in combination with pembrolizumab. When the recommended Phase 2 dose (RP2D) is determined, additional patients will be enrolled in an expansion cohort.

In Phase 2, patients will be randomized to receive Reqorsa with pembrolizumab or docetaxel +/- ramucirumab (active comparator).

Full Description

Acclaim-2 is a multi-center, open-label 2-arm study of Reqorsa in combination with pembrolizumab versus docetaxel +/- ramucirumab (active comparator) in previously treated 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 Reqorsa 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 Reqorsa doses will be tested (0.06, 0.09 and 0.12 mg/kg administered on Day 1 of a 21-day treatment cycle). Once the RP2D is identified an expansion cohort will be enrolled to better characterize safety, tolerability, and preliminary anti-tumor activity.

The Phase 2 portion of the study is a randomized, open-label 2-arm study of Reqorsa in combination with pembrolizumab versus docetaxel ± ramucirumab. In Phase 2, 126 patients will be randomized 2:1 to the investigational versus comparator treatment arms, respectively. Patients will be stratified by NSCLC histology (squamous [SQ] versus nonsquamous [NSQ]) predominant histology for efficacy analysis purposes. The 84 patients randomized to the combination arm will receive Reqorsa, at the RP2D identified in Phase 1, in combination with 200 mg pembrolizumab either during each 21- day cycle until disease progression or unacceptable toxicity as determined by the investigator. The 42 patients randomized to the active comparator arm will receive docetaxel at the FDA- approved dose of 75 mg/m2 every 21 days until disease progression or unacceptable toxicity as determined by the investigator. Investigators are permitted to administer docetaxel in combination with ramucirumab at their discretion.

Eligibility Criteria

Inclusion Criteria:

Adults ≥ 18 years of age.
Voluntarily signed an informed consent in accordance with institutional policies.
Histologically or cytologically documented NSCLC with locally advanced or metastatic disease. Note: Any level of PD-L1 TPS is allowed.
Achieved clinical benefit to prior pembrolizumab or pembrolizumab/platinum-based chemotherapy for at least 3 months and subsequently progressed as confirmed by radiological tumor assessment. Patients receiving pembrolizumab as a single agent must have additional therapy with a platinum-based chemotherapy prior to enrolling, but patients receiving pembrolizumab/platinum-based chemotherapy should have enrollment in this trial as the next treatment regimen.
Patients with genetic alterations with FDA-approved therapy (such as EGFR or anaplastic lymphoma kinase [ALK] mutations) must have disease progression after treatment with appropriate targeted therapy and must be eligible for immunotherapy as determined by the investigator.
Eastern Cooperative Oncology Arm (ECOG) performance score from 0 to 1.
Must be ≥ 28 days beyond major surgical procedures such as thoracotomy, laparotomy, or joint replacement, and must be ≥ 10 days beyond minor surgical procedures such as biopsy of subcutaneous tumors, pleuroscopy, etc., and must not have evidence of wound dehiscence, active wound infection, or comparable major residual complications of the surgery.

Demonstrate adequate organ function, as determined by the following laboratory values obtained within 21 days prior to enrollment:

Absolute neutrophil count (ANC) ≥ 1,500/μL,
Platelets ≥ 100,000/μL,
Hemoglobin ≥ 9.0 g/dL ≥ 4 weeks without transfusions,
International Normalized Ratio (INR) or Prothrombin Time (PT): ≤ 1.5 × upper limit of normal (ULN) unless the patient is receiving anticoagulant therapy as long as PT is within therapeutic range of intended use of anticoagulants,
Activated Partial Thromboplastin Time (aPTT) or Partial Thromboplastin Time (PTT): ≤ 1.5 × ULN unless the patient is receiving anticoagulant therapy as long as aPTT is within therapeutic range of intended use of anticoagulants,
Creatinine ≤ 1.5 × ULN OR Calculated creatinine clearance (CrCl) ≥ 60 mL/min for patients with creatinine levels > 1.5 × ULN,
Serum total bilirubin ≤ 1.0 × ULN,
AST and ALT ≤ 1.5 × ULN,
Alkaline phosphatase ≤ 2.5 x ULN.
Stable cardiac condition with a left ventricular ejection fraction > 40%.

If asymptomatic brain metastases are present, must meet ALL criteria listed (a-d):

No history of seizures in the preceding 6 months,
Definitive treatment must be completed ≥ 4 weeks prior to enrollment,
Stopped steroid treatments administered because of brain metastases or related symptoms for ≥ 2 weeks prior to enrollment,
Post-treatment imaging must demonstrate stability or regression of the brain metastases.
Female patients must have a negative serum pregnancy test at screening (within 7 days of enrollment) if of childbearing potential or be of non-childbearing potential.
Female patients of childbearing potential and non-sterile male patients with female partner(s) of childbearing potential must agree to use two forms of contraception including one highly effective and one effective method beginning ≥ 2 weeks prior to enrollment through 4 months following the last dose of study treatment.
Male patients must agree to no sperm donation during study treatment and for an additional 4 months following the last dose of study treatment.

Exclusion Criteria:
