Scott Praill, DelMar’s Chief Financial Officer, will present a corporate overview and provide an update on the ongoing Phase II clinical trial of VAL-083 (dianhydrogalactitol) in patients with recurrent glioblastoma multiforme (GBM). DelMar recently completed enrollment in the Phase II expansion cohort of the study and confirmed 40mg/m2 as the maximum tolerated dose (MTD) for advancement into registration-directed Phase II/III clinical trials in GBM.
Mr. Praill will also discuss the Company’s plans to initiate clinical trials with VAL-083 as a potential treatment for non-small cell lung cancer (NSCLC) and the promising potential of VAL-083 as chemotherapeutic alternative in ovarian cancer, pediatric brain tumors and other solid tumors.
A live audio webcast of the presentation will be available by accessing DelMar’s IR Calendar in the Investors section of the Company’s website (www.DelMarPharma.com). The webcast replay will be available approximately two hours after the presentation and will be accessible for one month.
About VAL-083
VAL-083 is a "first-in-class," small-molecule chemotherapeutic. In more than 40 Phase I and II clinical studies sponsored by the U.S. National Cancer Institute, VAL-083 demonstrated clinical activity against a range of cancers including lung, brain, cervical, ovarian tumors and leukemia both as a single-agent and in combination with other treatments. VAL-083 is approved in China for the treatment of chronic myelogenous leukemia (CML) and lung cancer, and has received orphan drug designation in Europe and the U.S. for the treatment of malignant gliomas.
DelMar has demonstrated that VAL-083’s anti-tumor activity is unaffected by the expression of MGMT, a DNA repair enzyme that is implicated in chemotherapy resistance and poor outcomes in GBM patients following standard front-line treatment with Temodar (temozolomide).
DelMar recently announced the completion of enrollment in a Phase II clinical trial of VAL-083 in refractory GBM. Patients have been enrolled at five clinical centers in the United States: Mayo Clinic (Rochester, MN); UCSF (San Francisco, CA) and three centers associated with the Sarah Cannon Cancer Research Institute (Nashville, TN, Sarasota, FL and Denver, CO).
In the Phase I dose-escalation portion of the study, VAL-083 was well tolerated at doses up to 40mg/m2 using a regimen of daily x 3 every 21 days. Adverse events were typically mild to moderate; no treatment-related serious adverse events reported at doses up to 40 mg/m2. Dose limiting toxicity (DLT) defined by thrombocytopenia (low platelet counts) was observed in two of six (33%) of patients at 50 mg/m2. Generally, DLT-related symptoms resolved rapidly and spontaneously without concomitant treatment, although one patient who presented with hemorrhoids received a platelet transfusion as a precautionary measure.
Sub-group analysis of data from the Phase I dose-escalation portion of the study suggested a dose-dependent and clinically meaningful survival benefit following treatment with VAL-083 in GBM patients whose tumors had progressed following standard treatment with temozolomide, radiotherapy, bevacizumab and a range of salvage therapies.
Patients in a low dose (≤5mg/m2) sub-group had a median survival of approximately five (5) months versus median survival of approximately nine (9) months for patients in the therapeutic dose (30mg/m2 & 40mg/m2) sub-group following initiation of VAL-083 treatment. DelMar reported increased survival at 6, 9 and 12 months following initiation of treatment with VAL-083 in the therapeutic dose sub-group compared to the low dose sub-group.
