This clinical trial will evaluate the combination of quaratusugene ozeplasmid with atezolizumab as maintenance therapy for patients with Extensive Stage Small Cell Lung Cancer (ES-SCLC). The study is comprised of 2 phases, a dose selection phase (Phase 1) and a safety and efficacy evaluation phase (Phase 2).
Acclaim-3 is an open-label, multi-center, Phase 1/2 study evaluating the combination of quaratusugene ozeplasmid with atezolizumab as maintenance therapy for patients with ES-SCLC who did not develop tumor progression after receiving at least 3 cycles, and no more than 4 cycles, of induction therapy with carboplatin plus etoposide and atezolizumab. 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 (DLTs) will be reviewed by…
Inclusion Criteria: * Male or female aged ≥18 years. * Documented history of histologically or cytologically confirmed ES-SCLC, prior to starting treatment with the combination of atezolizumab, carboplatin, and etoposide * Complete Response (CR), Partial Response (PR), or Stable Disease (SD) after receiving at least three cycles, and no more than four cycles, of atezolizumab, carboplatin, and etoposide. * Eastern Cooperative Oncology Group performance status (ECOG PS) score from 0 to 1. * Must be ≥28 days beyond major surgical procedures such as thoracotomy, laparotomy, or joint replacement,…
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.
