Poster on Celsion Corporation’s Phase I/II OVATION 2 Study Presented at the Society of Gynecologic Oncology Virtual Annual Meeting on Women’s Cancer
Company reports further strengthening of R0 resection results in patients treated with GEN-1
GEN-1 is Celsion’s DNA-mediated interleukin-12 (IL-12) immunotherapy designed using TheraPlas, its proprietary, synthetic, non-viral nanoparticle delivery system platform. The poster was presented by
“Currently advanced ovarian cancer has a low survival rate and a lack of effective therapies. PARP inhibitors have made an important contribution in a subset of patients. For the majority of patients there is hope that an immunotherapy such as GEN-1 will provide a valuable new treatment option to improve both the quality of life and the life expectancy for these women,” commented
The poster describes the OVATION 2 Study, which combines GEN-1 with standard-of-care neoadjuvant chemotherapy (NACT) in patients newly diagnosed with Stage III/IV ovarian cancer. NACT is designed to shrink the cancer as much as possible for optimal surgical removal after three cycles of chemotherapy. Following NACT, patients undergo interval debulking surgery, followed by three adjuvant cycles of chemotherapy and up to nine additional weekly GEN-1 treatments, the goal of which is to delay progression and improve overall survival. The OVATION 2 Study is an open-label, 1-to-1 randomized trial, 80% powered to show the equivalent of a 33% improvement in progression-free survival (PFS) (HR=0.75), the primary endpoint, when comparing the treatment arm (standard of care + GEN-1) with the control arm (standard of care alone).
The Company recently announced that it has enrolled approximately 40% of the anticipated 110 patients to be enrolled into the OVATION 2 Study. To date, 29 patients have had their interval debulking surgery with the following results:
- 14 of 17, or 82%, of patients treated with GEN-1 had a R0 resection, which indicates a microscopically margin-negative complete resection in which no gross or microscopic tumor remains in the tumor bed.
- 7 of 12 patients, or 58%, of patients in the control arm had an R0 resection.
- This interim data represents a 41% improvement in R0 resection rates for GEN-1- patients compared with control arm patients and is consistent with the reported improvement in resection scores noted in the encouraging Phase I OVATION 1 Study, the manuscript of which has been submitted for publication in a peer-reviewed journal.
