Clinical Trial: Safety and Efficacy of Oral Deferasirox in Patients With Porphyria Cutanea Tarda

Study Status: Recruiting
Recruit Status: Unknown status
Study Type: Interventional

Official Title: A Phase II, Open Label Clinical Trial Exploring the Safety and the Efficacy of Oral Deferasirox in Patients Newly Diagnosed With Porphyria Cutanea Tarda (PCT) and Non-tran

Brief Summary: While clinical phlebotomy is current standard practice for alleviating non-transfusion iron overload in patients with PCT, it may not be suitable for all patients. For example, some patients are unwilling to be adequately phlebotomized because of inconvenience, as phlebotomy can be cumbersome, especially during the induction treatment phase requiring frequent clinic visits (twice a month, for at least 6 months) or because of venous access difficulties. Other patients are unable to undergo phlebotomy due to medical reasons such as anemia or cardiopulmonary disorders. It is postulated such patients with PCT who have non-transfusion iron overload could benefit from treatment with deferasirox (Exjade®), a once daily oral iron chelator licensed in several countries, including the EU, for treating transfusion iron overload in adult and pediatric patients. Although there is some data on the efficacy and safety of deferasirox in patients with HH, who, like those with PCT, have non-transfusional iron overload, there is a need to evaluate the safety and efficacy of deferasirox treatment of non-transfusion iron overload in patients with PCT.

Detailed Summary:

The primary objective is to assess the safety of deferasirox in treating non-transfusion iron overload in patients with PCT.

The secondary objective is to assess the effectiveness of deferasirox treatment :

After 3 and 6 months to:

•Lower serum ferritin from abnormal to normal standard ranges specified for males and females in this patient population.

After 6 months to :

•Lower liver iron content after 24 weeks of treatment measured by liver MRI T2

After 3 and 6 months to :

  • Improve clinical symptoms, i.e. improvement in skin lesions (reduction or no new bullae formation), and skin fragility (photographs will be used).
  • Reduce porphyrin levels.

Current Primary Outcome:

  • The primary objective is to assess the safety of deferasirox in treating non-transfusion iron overload in patients with PCT. [ Time Frame: 6 months ]
  • Related drug adverse events [ Time Frame: 6 months ]
    Incidence type and severity of drug related adverse events


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • The change from baseline in serum ferritin after 12 and 24 weeks of treatment,The change from baseline in iron burden after 24 weeks of treatment measured by liver MRI T2,The evolution of clinical symptoms [ Time Frame: 6 months ]
  • Chage from baseline in serum ferritin, iron burden, improvement in clincal symptoms, porphyrin levels [ Time Frame: 6 months ]


Original Secondary Outcome: Same as current
