2 Clinical Trials for Various Conditions
The primary objective of this study is to evaluate the effect of oral eleclazine on mean daytime QTcF interval after 24 weeks of treatment with elecalzine in participants with long QT syndrome Type 3. During the single-blind treatment period (24 weeks), participants will receive eleclazine and/or eleclazine placebo. Following the single-blind treatment period, participants who have not permanently discontinued study drug will be eligible, at the discretion of the investigator, to continue receiving eleclazine during an open-label extension (OLE) phase.
Part 1: This is a Phase 1b, randomized, double-blind, crossover, dose escalation, placebo-controlled study to evaluate the effect of oral LQT-1213 on dofetilide-induced QTc prolongation in healthy adult subjects. This is a 2-treatment, 2-period crossover study with approximately up to 28 healthy subjects, with screening procedures within 28 days of enrolment. Part 2: This is a Phase 2a, single-blind, placebo run-in, multiple-dose safety study to evaluate the safety, tolerability, and PK of LQT-1213 in patients diagnosed with LQT1, LQT2 or LQT3. Up to 12 participants with LQT1, up to 20 participants with LQT2 and up to 12 participants with LQT3 will be recruited.
