Summary

The main OBJECTIVE of this proposal is to extend our preclinical findings on the role of DNA damage and poly(ADP-ribose) polymerases (PARP) inhibition as a therapy for a devastating disease, pulmonary arterial hypertension (PAH), to early-phase clinical trials. We, and others, have published strong evidence that DNA damage accounts for disease progression in PAH and showed that PARP1 inhibition can reverse PAH in several animal models1. Interestingly, PARP1 inhibition is also cardioprotective. Olaparib, an orally available PARP1 inhibitor, can reverse cancer growth in animals and humans with a good safety profile, and is now approved for the treatment of ovarian cancer in Canada, Europe and the USA. The time is thus right to translate our findings in human PAH. The industry-sponsored clinical research on PARP1 inhibitor is currently entirely cancer-oriented. Nonetheless, AstraZeneca Canada accepted to support an early phase clinical trial through in-kind contribution, but the support from foundations and federal agencies is critical to catalyze early-stage development of PARP1 inhibitors for other indications, especially for orphan diseases. A CIHR Project Scheme grant will thus be submitted on September 15 2017, proposing a Phase 1, followed by a Phase 2 trial that will be conducted in recognized PAH programs throughout Canada. At this stage, however, we propose a pilot study to assess the feasibility of the proposed trials in the PAH population. The overall HYPOTHESIS is that PARP1 inhibition with olaparib is a safe and effective therapy for PAH.

The primary objective of the study is to confirm feasibility, to support the safety of using olaparib in PAH patients, and precise the sample size of the coming Phase 1B trial. The feasibility of the comprehensive patient phenotyping that will be proposed within the phase 1B trial will thus be assessed, in addition to adverse events and efficacy signals.
