The completed lead evidence has the design features that historically survive confirmatory trials: randomized, controlled, and adequately powered against a prespecified clinically accepted endpoint.
NCT03626688: This was a randomized, quadruple-blind, placebo-controlled trial with 687 participants, measuring time to a clinical worsening event as the primary endpoint. The sponsor reports a 55% reduction in the risk of clinical worsening for ralinepag versus placebo, a statistically significant result.
Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.
