“Initial data from the PTCL cohort in NAVAL-1 show a strong signal of efficacy that is in-line with our promising Phase 1b/2 data and sufficient to advance to Stage 2. We now look forward to completing enrollment in Stage 1 and are taking steps to further accelerate enrollment through Stage 2,” said Mark Rothera, President and Chief Executive Officer of Viracta. “Given the lack of effective therapies available for patients with PTCL, today’s announcement represents an important step towards addressing a pressing unmet medical need. The advancement of the first cohort into Stage 2 establishes PTCL as the leading indication for the NAVAL-1 clinical trial and provides added momentum to our global clinical program.”
