Milestone Pharmaceuticals said that it has raised $25 million from RTW Investments in a private placement and indicated that the proceeds would be sufficient for company operations through the second quarter of 2022. The company also announced that it had reached an agreement with the FDA regarding modifications to the design of a pivotal trial of its etripamil nasal spray for the treatment of paroxysmal supraventricular tachycardia (PSVT).
In March 2020, Milestone announced that the Phase 3 NODE-301 trial had missed its primary endpoint, which was time to conversion of SVT to sinus rhythm compared to placebo over the five hours post dose. At the time, the company noted that data collected sooner after dosing showed greater benefits for etripamil.
Milestone Pharmaceuticals President and CEO Joseph Oliveto commented, “We are pleased with the outcome of our recent interactions with the FDA, as they outline an efficient path to registration for etripamil which eliminates the need to start a new Phase 3 study. The FDA agreed with our plan to modify the ongoing NODE-301B study, now known as the RAPID study, to highlight the unique pharmacology of etripamil, including a primary endpoint of time to conversion within 30 minutes. This study, together with our recently completed NODE-301 study, which will also now use a 30 minute endpoint, will serve to fulfill the efficacy requirements for a New Drug Application (NDA) for etripamil in PSVT.”
Oliveto added, “In addition to expanding the RAPID study, the modified design will direct patients to administer an additional dose of study drug 10 minutes after the first dose if they still experience signs and symptoms of a supraventricular tachycardia (SVT) episode. We believe this dosing regimen provides a tailored approach to increase efficacy in patients with more persistent events and improve the overall clinical utility of etripamil. We look forward to reopening enrollment in the RAPID study later this year, with results anticipated in late 2021/early 2022.”
