简要总结
Porphyria cutanea tarda (PCT) is an iron-related disorder that responds to treatment by phlebotomy or low-dose hydroxychloroquine, but comparative data on these treatments are limited. The hypothesis is that hydroxychloroquine is noninferior to phlebotomy in terms of time to remission. Patients with well documented PCT are assigned to treatment by randomization if specific criteria are met. All patients are followed until remission - defined as achieving a normal plasma porphyrin concentration.
详细描述
Study Design: Pragmatic Interventional study
Primary Study Objective: To determine and compare time to remission with treatment with low-dose hydroxychloroquine or repeated phlebotomy in participants with PCT.
Secondary Study Objective(s):
- To assess the effects of susceptibility factors on responses to treatment of PCT by these methods.
- To determine and compare rates of recurrence of PCT after treatment with low-dose hydroxychloroquine or phlebotomy.
