A Double-blind, Randomized, Placebo-controlled, Parallel Group Trial on the Efficacy and Safety of PanhematinTM in the Treatment of Acute Attacks of Porphyria

Detailed Summary

This study aims to provide high quality evidence for the effectiveness and safety of hemin (PanhematinTM , Recordati) for treatment of acute attacks of porphyria. These types of studies have not been done before with either PanhematinTM or the hemin preparation available in Europe (NormosangTM, Orphan Europe). There are two treatment groups in this study. One group will be treated with PanhematinTM plus glucose, and the other group will be treated with glucose plus an inactive salt solution (called a "placebo"). To avoid prejudice, the treatment given to each participant will be blinded (meaning the participants and most of the hospital staff will not know which treatment the participant will receive) and randomized (meaning participants will have an equal chance of receiving either treatment, like the flip of a coin). A placebo-controlled, randomized study is the standard method used to prove treatments are effective and safe. PanhematinTM and glucose will be given in the same manner as is usual for treating an attack of porphyria. For participants who are chosen to receive the placebo, their treatment will be switched to real PanhematinTM at any time if their symptoms do not improve. This is called "rescue" treatment, and assures that they study is safe and patients who need hemin will receive it. Treatment with hemin will be for 4 days, or longer if needed. Since the study treatment is started as soon as possible after symptoms appear, there will be very little delay in providing hemin to those who need it.
