A Phase 3 interventional study of IMNN-001 (IL-12 Plasmid Formulated with PEG-PEI-Cholesterol Lipopolymer) and Paclitaxel in Epithelial Ovarian Cancer, Ovarian Cancer and Fallopian Tube Cancer, sponsored by Imunon. Recruiting at 9 sites in United States. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-15.
Sponsored by Imunon · Phase 3, Interventional, and Treatment
This is a randomized, adaptive, open label, multicenter trial to evaluate the safety and efficacy of intraperitoneal (IP) IMNN-001 plus chemotherapy compared to chemotherapy alone.
Eligible participants will be randomly assigned 1:1 to receive either chemotherapy plus IMNN-001 or chemotherapy alone, followed by standard of care maintenance therapy.
Randomization will stratify by confirmed biomarker tumor homologous recombination deficiency status and stage of cancer.
On both arms, the chemotherapy regimen will consist of paclitaxel 175 mg/m2 IV over 3 hours followed by carboplatin AUC 6 IV over 1 hour on Day 1 of each cycle. This will be repeated every 3 weeks for a total of 6 cycles, 3 in the neoadjuvant period and 3 in the adjuvant period following interval debulking surgery (IDS). On the experimental arm, IMNN-001 at a dose of 100 mg/m2 will be administered IP on Days 8 and 15 of the first chemotherapy cycle and then on Days 1, 8, and 15 of all subsequent 5 chemotherapy cycles for a total of 17 treatments in the neoadjuvant and adjuvant settings. When given on the same day as chemotherapy, IMNN-001 should be given at least 30 minutes after completion of carboplatin infusion. IDS will take place after 3 cycles of neoadjuvant chemotherapy (NACT) + IMNN-001 for 8 doses. Additional cycles of NACT are allowed at the discretion of the investigator but with discussion with the medical monitor.
An independent Data Monitoring Committee (iDMC) will monitor participants' safety and study conduct throughout the course of the trial.
Participants must have adequate:

Overall Survival
Overall Survival is defined as the time (in months) from the date of randomization to the date of death by any cause.
Time frame: 48 months
Chemotherapy Response Score
After the interval debulking surgery takes place, participants will be assessed for a chemotherapy response score by the pathologist and scored based on CRS3, CRS2, or CRS1.
Time frame: 12 weeks
Surgical Response
After the interval debulking surgery takes place, participants are scored in terms of their interval debulking status with a score of R0, R1, or R2.
Time frame: 12 weeks
Time to Second Line Treatment
Time to second line treatment is defined as the time (in months) from the date of randomization to the date of second line chemotherapy treatment or death, whichever occurs first.
Time frame: 13 months
Objective Response Rate
Objective Response Rate is defined as the proportion of participants with objective evidence of CR or PR prior to IDS. The evaluation of objective response rate will be based on investigator (site) assessment of the images following RECIST v1.1 criteria.
Time frame: 12 weeks
