"The clinical development program for VB-111, our unique gene therapy for solid tumors, continues to advance well. Patient enrollment in the OVAL Phase 3 study in ovarian cancer continues to be ahead of plan, with almost 200 patients enrolled to date. We had two positive DSMC analyses, indicating that our OVAL trial remains on the right track," said Dror Harats, M.D., Chief Executive Officer of VBL Therapeutics. "While it is important to note that the study remains blinded, we are encouraged by the very high response rate (RR), over 50%, that we continue to see to date. This RR is impressively higher than expected for standard-of-care treatments, for which RR is typically in the teens. If successful, the OVAL trial has the potential to establish VB-111 as a new standard of care in a challenging disease setting where patients currently have limited options."

Vascular Biogenics Ltd., operating as VBL Therapeutics, is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of first-in-class treatments for areas of unmet need in cancer and immune/inflammatory indications. VBL has developed three platform technologies: a gene-therapy based technology for targeting newly formed blood vessels with focus on cancer, an antibody-based technology targeting MOSPD2 for anti-inflammatory and immuno-oncology applications, and the Lecinoxoids, a family of small-molecules for immune-related indications. VBL's lead oncology product candidate, ofranergene obadenovec (VB-111), is a first-in-class, targeted anti-cancer gene-therapy agent that is being developed to treat a wide range of solid tumors. It is conveniently administered as an IV infusion once every 6-8 weeks. It has been observed to be well-tolerated in >300 cancer patients and demonstrated activity signals in a VBL-sponsored "all comers" Phase 1 trial as well as in three VBL-sponsored tumor-specific Phase 2 studies. Ofranergene obadenovec is currently being studied in a VBL-sponsored Phase 3 potential registration trial for platinum-resistant ovarian cancer.
