Travere annnounces voluntary pause of nnrollment in the Phase 3 HARMONY study

Travere Therapeutics announced a voluntary pause of enrollment in the Phase 3 HARMONY Study evaluating pegtibatinase for the treatment of classical homocystinuria HCU . The voluntary enrollment pause enables the Company to work to address necessary process improvements in manufacturing scale-up to support commercial scale manufacturing as well as full enrollment in the HARMONY Study. Patients currently enrolled in pegtibatinase studies continue to receive study medication from small scale batches which are unaffected by the scale-up process. Currently enrolled patients will be able to continue on study medication as scheduled for the duration of the trials they are participating in. The voluntary enrollment pause was enacted following the Company’s determination that the desired drug substance profile was not achieved in the recent scale-up process. The Company is in the process of notifying all study investigators of the decision to pause enrollment of new patients into the study until additional material is available. “We believe the potential for pegtibatinase to become the first disease-modifying therapy for classical HCU remains unchanged. Our internal team and external manufacturing partners have extensive biologics expertise, and we are confident that we will be able to make the necessary manufacturing process improvements to continue with this pivotal program. We remain committed to supporting the patients currently enrolled in our clinical trials while working with our manufacturing partners to optimize our commercial-scale manufacturing process,” said Bill Rote, Ph.D., senior vice president of research and development at Travere Therapeutics.
