IMV Inc., a clinical stage immuno-oncology corporation, today announced preliminary data from the phase 2 cohort of the DECIDE clinical study. Six patients receiving DPX-Survivac monotherapy with intermittent low-dose cyclophosphamide (mCPA) have reached the first CT scan assessment with key related findings as follows:
- 83% of the subjects (5 of 6) show stable disease (SD), including two tumor regressions
- 80% (4 of 5) with stable disease are in subjects with a lower baseline tumor burden (BTB), which also includes the two tumor regressions
“This initial phase 2 data confirms the earlier trends we saw in the phase 1b portion of the study,” said Frederic Ors, Chief Executive Officer. “It supports the potential of DPX-Survivac as a monotherapy and the use of our patient selection strategy. We are encouraged by these early initial results and are committed to advancing this program quickly with the goal of providing an additional treatment option to patients with advanced ovarian cancer.”
Importantly, in earlier stages of this trial, durable clinical responses occurred after 140 days, and have now lasted for 20 months or more. Additional data at the 140 day mark of this cohort will be available by the end of the first half of 2019.
This amended phase 2 study evaluates the safety and efficacy of DPX-Survivac monotherapy with mCPA in patients with advanced recurrent ovarian cancer. As of the March 25, 2019 data cut-off date, 13 patients have been enrolled in the phase 2 portion of the trial in addition to the 53 enrolled in the phase 1b cohort. Five patients were randomized into the DPX-Survivac monotherapy cohort. Seven patients had been randomized into DPX-Survivac/mCPA in combination with epacadostat before the phase 2 protocol was amended to stop enrollment in the combination arm. One of the patients in the combination arm elected to switch to the monotherapy arm of the trial. Positive data from the phase 1b portion of the trial led IMV to amend the study to monotherapy in patients with lower tumor burden.
The amended phase 2 cohort of the DECIDE trial is targeting an enrollment of at least additional 16 patients in the population with a lower tumor burden. Enrollment is ongoing at multiple sites in the U.S. and Canada.
