"These positive data indicate that SRA737 is a demonstrably active anti-cancer drug that we believe warrants further development. The initial efficacy and favorable tolerability profile described at ASCO also enables several potentially promising opportunities for its development in combination with other therapeutics, in particular with PARP inhibitors and immunotherapy agents where we have previously reported robust preclinical efficacy data," said Dr. Nick Glover, President and CEO of Sierra Oncology. "We also look forward to announcing regulatory clarity for our lead asset momelotinib in the near-term. We have been holding productive discussions with regulators and continue to prepare for a Phase 3 clinical trial intended to potentially support its registration. Given momelotinib is our lead drug candidate and highest priority, we will be exploring options to enable the continued advancement of SRA737 in the context of our emerging pipeline."
