- OVAL independent Data Safety Monitoring Committee (DSMC) reviewed un-blinded data and determined that the study has met the interim pre-specified criterion of an absolute percentage advantage of 10% or higher in CA-125 response in the VB-111 treated arm compared to control. The DSMC recommended that the study proceed without modification.
- Overall CA-125 response rate in the first 60 randomized evaluable patients is 53%. Assuming a balanced randomization, the response rate in the treatment arm (VB-111 in addition to weekly paclitaxel) is 58% or higher.
- In patients with post-treatment fever, the CA-125 response is 69%. Fever is frequently observed after VB-111 treatment.
- The next interim analysis in the OVAL study is expected in 3Q 2020.
TEL AVIV, Israel I June 01, 2020 I VBL Therapeutics (Nasdaq: VBLT), today announced the presentation of the positive outcome of pre-planned interim analysis results from the OVAL Phase 3 pivotal clinical trial in platinum-resistant ovarian cancer at the American Society of Clinical Oncology (ASCO) 2020 virtual annual meeting.
The analysis compared the CA-125 objective response rate (ORR) according to GCIG criteria in the treatment and control arms among the first 60 evaluable patients. The CA-125 ORR in those patients was 53%. Assuming a balanced randomization, the response rate in the treatment arm (VB-111 in addition to weekly paclitaxel) was 58% or higher. In patients who had post-dosing fever, which is a marker for VB-111 treatment, the response rate was 69%.
The CA-125 response rate observed in the Phase 3 interim analysis is at least as good as the response rate seen in the prior Phase 2 study, which enrolled a similar patient population and showed overall survival benefit. In the previously reported Phase 2 study of VB-111 in platinum resistant ovarian cancer, 58% of the patients treated with VB-111 and paclitaxel demonstrated a CA-125 response. Those patients with a CA-125 response demonstrated a median overall survival of 808 days, versus 351 days for those patients without a CA-125 response.
“The OVAL interim data are very encouraging as they demonstrate the potential benefit of VB-111 over standard-of-care in a randomized-controlled setting,” said Tami Rachmilewitz, M.D., Vice President Clinical Development of VBL Therapeutics. “With over 25% of the patients already enrolled in the study, we look forward to further advancing the OVAL study by expansion to Europe and Japan later this year.”

About the OVAL (VB-111-701/GOG-3018) study (NCT03398655)
OVAL is an international Phase 3 randomized, double-blind, placebo-controlled potential registration clinical trial that compares a combination of VB-111 and paclitaxel to placebo plus paclitaxel, in patients with platinum-resistant ovarian cancer. The study is planned to enroll approximately 400 patients. OVAL is conducted in collaboration with the GOG Foundation, Inc., an independent international non-profit organization with the purpose of promoting excellence in the quality and integrity of clinical and basic scientific research in the field of gynecologic malignancies.
About VB-111 (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. VB-111 is a unique biologic agent that uses a dual mechanism to target solid tumors. Its mechanism combines blockade of tumor vasculature with an anti-tumor immune response. VB-111 is 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 an “all comers” Phase 1 trial as well as in three tumor-specific Phase 2 studies. VB-111 has received an Orphan Designation for the treatment of ovarian cancer from the European Commission. VB-111 has also received orphan drug designation in both the US and Europe, and fast track designation in the US for prolongation of survival in patients with rGBM. VB-111 successfully demonstrated proof-of-concept and survival benefit in Phase 2 clinical trials in radioiodine-refractory thyroid cancer and recurrent platinum-resistant ovarian cancer (NCT01711970).
