On November 16, 2018 VBL Therapeutics (Nasdaq: VBLT), is reported its results today from its Phase 3 GLOBE study in patients with recurrent glioblastoma (rGBM) which was designed to evaluate VB-111 in combination with bevacizumab (Avastin) (`treatment arm`), compared to bevacizumab (`control arm`) (Press release, VBL Therapeutics, NOV 16, 2018, View Source [SID1234531393]). In March 2018, VBL announced top-line data for the study, which did not demonstrate a benefit in overall survival (OS) or progression-free survival for the treatment arm relative to the bevacizumab control.

The GLOBE data are being presented today at the 2018 Society for Neuro-Oncology Annual Meeting by Dr. Timothy Cloughesy, MD, Professor of Clinical Neurology and Director of the Neuro-Oncology Program, UCLA School of Medicine and principal investigator of the GLOBE trial. The data include further analyses of the GLOBE data including baseline prognostic factors and subgroups analysis. Data show that the baseline tumor volume, which is a significant prognostic factor in rGBM, was higher in the treatment arm compared to the control arm. Overall, the subjects in the study had relatively high tumor volume, as large-volume tumors were not an exclusion criterion. It is of interest that patients with smaller tumors (<15 cm3) appeared to respond better to the treatment arm, with numerically higher response rate and overall survival observed. Furthermore, a trend towards greater survival was observed in patients treated with VB-111 who reported fever. VB-111 was well tolerated, with a similar early termination rate in both the treatment and control arms. Most frequent adverse event was self-limited fever, starting several hours post therapy and usually resolving by 24 hours. As expected, a higher rate of SAEs and grade >=3 AEs was reported in the combination treatment arm.

Subsequent analyses have focused on the potential reasons for the major differences in outcomes between the positive VB-111 Phase 2 clinical trial in rGBM and the unsuccessful GLOBE results. The Phase 2 trial of VB-111 met the primary endpoint of OS benefit with median OS (mOS) of 13.6 months upon treatment with VB-111 as a single drug (`priming`) followed by adding bevacizumab to VB-111 upon further progression, compared to mOS of 6.8 months for the treatment arm in GLOBE (co-administration of VB-111 and bevacizumab, without any VB-111 monotherapy `priming` period).

Thorough analyses of the baseline risk factors of the Phase 2 and the Phase 3 treatment groups did not reveal any differences. Therefore, patient selection or different patient populations could not explain the difference between the results of the two studies. The only significant change between the Phase 2 and Phase 3 treatment cohorts was in the treatment regimen – the regimen for Phase 2 trial included priming with VB-111 whereas the regimen for GLOBE trial did not.

To test the hypothesis that concomitant treatment with bevacizumab may have a negative effect on VB-111 activity, the Company investigated this combination in a pre-clinical tumor model. The results indicate that treatment with VB-111 in combination with bevacizumab appears to block the anti-tumor the effect of VB-111, compared to VB-111 monotherapy. In addition, a retrospective analysis of a small cohort of 10 patients who were treated concomitantly with VB-111 and bevacizumab for safety evaluation (no priming), was inferior to what was observed with VB-111 priming in the Phase 2 study.

To better understand these results, the Company is collaborating with UCLA scientists in performing thorough analyses of MRI scans for VB-111-primed combination arm patients from the Phase 2 trial, compared to the un-primed combination arm patients in the GLOBE trial.

"Our initial exploratory analyses demonstrate clear radiologic responses over time in rGBM patients treated with VB-111 in the Phase 2 trial, both on VB-111 monotherapy and in combination with bevacizumab after priming with VB-111 alone, which were translated to overall survival. We are currently analyzing the GLOBE MRI scans to see if this signature of VB-111 activity is lost in the GLOBE combination group and will report the outcome upon completion of the analysis," said Dr. Cloughesy.

"The new analyses we have been conducting provide insight into how the VB-111 treatment regimen may influence its anti-tumor effect and help us understand why the positive Phase 2 data were not replicated in the GLOBE Phase 3 study," said Dror Harats, M.D., Chief Executive Officer of VBL Therapeutics. "We believe that priming with VB-111 without bevacizumab may be critical for the immune and vascular-disruptive/anti-angiogenic mechanism of VB-111 in rGBM. We continue to have confidence in the ongoing OVAL Phase 3 study of VB-111 in platinum-resistant ovarian cancer patients, whose protocol takes into account lessons learned from our GBM trial. The OVAL Phase 3 study is evaluating VB-111 in combination with chemotherapy rather than Avastin. The combination of VB-111 with paclitaxel worked well both in pre-clinical settings and in our Phase 2 for ovarian cancer, including in patients whose tumors progressed on prior treatment with Avastin. In OVAL, we are repeating exactly the same successful Phase 2 regimen."

About the GLOBE study

The GLOBE pivotal Phase 3 trial was a randomized, controlled, double-arm, open-label study of VB-111 dosed every two months in combination with bevacizumab dosed every two weeks, compared to bevacizumab monotherapy. Key inclusion criteria included first or second progression of glioblastoma following standard of care treatment with temozolomide and radiation, a histologically confirmed diagnosis of glioblastoma and measurable disease by RANO criteria at progression.

The study was conducted under a Special Protocol Assessment (SPA) granted by the FDA, with full endorsement by the Canadian Brain Tumor Consortium (CBTC). VB-111 has received orphan drug designation in the United States and Europe and was granted Fast Track designation by the FDA for promising and meaningful long-term survival in patients with glioblastoma that has recurred following treatment with standard chemotherapy and radiation.

"There are limited treatment options available for patients with newly diagnosed and recurrent/refractory glioblastoma. This trial was designed to evaluate the potential synergies between DNA damaging therapies and/or agents and our investigational PARP inhibitor, pamiparib, which in pre-clinical studies has demonstrated brain penetration and PARP trapping activity. We are excited to continue to assess the potential of pamiparib combinations for a variety of difficult-to-treat cancers where there is urgent global need," commented Amy Peterson, M.D., Chief Medical Officer for Immuno-Oncology at BeiGene.

"While response data are still maturing, these preliminary results demonstrated signs of antitumor activity of pamiparib in combination with radiation therapy in patients with newly diagnosed glioblastoma, as well as in combination with low-dose TMZ in patients with recurrent/refractory glioblastoma including those who previously progressed on TMZ, and support the continued development of these combinations," said Kent Shih, M.D., Senior Investigator of the Neuro-Oncology Program at Sarah Cannon Research Institute.

Summary of Preliminary Results

This open-label, multi-center global Phase 1b/2 multiple-dose and dose-escalation trial of pamiparib plus RT and/or TMZ (NCT03150862) was designed to evaluate the safety, efficacy and clinical activity of the combination in patients with newly diagnosed or R/R GBM. Patients with newly diagnosed GBM with unmethylated MGMT promoter status (Arm A) received pamiparib (60 mg twice a day) over escalating time periods (two, four, or six weeks) in combination with RT over six to seven weeks. Patients with R/R GBM (Arm C) received pamiparib (60 mg twice a day) continuously plus TMZ administered on Days 1 to 21 of each 28-day cycle. After evaluation of safety and tolerability from Arm A and C, Arm B will enroll patients with newly diagnosed GBM and treat them with the triple combination of RT, pamiparib, and TMZ.

As of September 14, 2018, a total of 18 patients with newly diagnosed GBM were enrolled in Arm A (n=3, 6 and 9 in the two-, four-, and six-week cohorts respectively). The median study follow-up duration is 19 weeks (2-54). Five grade >3 adverse events (AE) (chills, diarrhea, fatigue, nausea, vertigo, one [5.6%] each) were considered related to pamiparib or RT. Dose-limiting toxicities of fatigue, vertigo, and chills (one each) were reported.

As of the data cutoff date, 15 of the 18 patients were evaluable for response per modified response assessment in neuro-oncology (mRANO) criteria. Two of 15 patients achieved a partial response (PR, one was confirmed) and six patients achieved stable disease (SD); the disease control rate was 53.3% (95% CI: 26.6-78.7).

In Arm C, eight patients received TMZ at a fixed dose of 40 mg for 21 of 28 days and seven patients received 20 mg TMZ. The median study follow-up duration is 12.9 weeks (0.3-31.4). Grade >3 AEs included anemia (20%), fatigue (13.3%), and decreased lymphocyte (13.3%), which were considered related to pamiparib or TMZ. Dose-limiting toxicities of nausea and neutropenia were reported. The combination of 21 days of 40 mg TMZ with pamiparib was not tolerable; a lower 20 mg TMZ dose evaluation in combination with pamiparib is ongoing.

Ten of the 15 patients were evaluable per mRANO criteria and there were two PRs (one unconfirmed and one confirmed after data cutoff) and three SD.

About Glioblastoma Multiforme
Glioblastoma multiforme, also called glioblastoma, is an aggressive type of cancer where malignant grade IV tumors occur in the brain or spinal cord.2 These are the most common type of malignant brain tumors among adults.3 Symptoms include worsening headaches, nausea, vomiting and seizures. Patients can also present with neurological symptoms which are dependent on the tumor location (for example, weakness or sensory changes of face, arm or leg, balance difficulties and neurocognitive/memory issues).4 Glioblastoma can occur at any age but tends to occur more often in older adults. The five-year relative survival rates for patients with glioblastoma are: 19 percent (age 20-44), eight percent (age 44-54), and five percent (age 55-64).5

About Pamiparib
Pamiparib (BGB-290) is an investigational inhibitor of PARP1 and PARP2 which has demonstrated pharmacological properties such as brain penetration and PARP-DNA complex trapping in preclinical models. Discovered by BeiGene scientists in Beijing, pamiparib is currently in global clinical development as a monotherapy and in combination with other agents for a variety of solid tumor malignancies.
