Study Endpoints
Primary Endpoints
Recommended Phase 2 Dose (RP2D) - Phase 1
First 21-day treatment cycle for each dose level cohort

RP2D, which will be the maximum tolerated dose (MTD) or, if the MTD is not defined by the safety data, RP2D will be determined based on an integrated assessment of all available clinical safety and preliminary efficacy data.

Overall Response Rate (ORR) - Phase 2a
Approximately 3 months

ORR (complete response \[CR\]+ partial response \[PR\]) according to RECIST using best overall response.

Progression-free Survival (PFS) - Phase 2b
Approximately 11 months

PFS from randomization to disease progression or death. Response according to RECIST.

Secondary Endpoints
Progression-free Survival (PFS) - Phase 1
Approximately 9 months
Overall Response Rate (ORR) - Phase 1
Approximately 3 months
Duration of Response (DOR) - Phase 1

ArmTypeDescription
InvestigationalEXPERIMENTALIn 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.
ControlACTIVE_COMPARATORIn the control arm of Phase 2b, patients will receive platinum-based chemotherapy until disease progression or unacceptable toxicity.
Interventions
NameTypeDescription
quaratusugene ozeplasmidBIOLOGICALQuaratusugene 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.
osimertinibDRUGOsimertinib is a 3rd generation EGFR tyrosine kinase inhibitor (TKI) oral tablet administered daily, as indicated for treatment of patients with metastatic NSCLC whose tumors have EGFR genetic deletions or mutations.
Platinum-Based ChemotherapyDRUGCisplatin and carboplatin are intravenously administered platinum agents that are combined with other cytotoxic chemotherapy agents such as pemetrexed.
