LTG-321 - Itraconazole Drug-drug Interaction (DDI) Study
A Phase 1, Open-Label Study to Evaluate the Effect of Strong CYP3A Inhibition on the Pharmacokinetics of LTG-321 in Healthy Participants
This Phase 1, single-center, open-label, randomized, parallel-group study will evaluate the effect of itraconazole on the PK of LTG-321 and its metabolite(s), and the safety and tolerability of LTG-321 administered alone and in combination with itraconazole, in healthy participants.
