All studies receiving U. Information about current research on porphyria also is available from the American Porphyria Foundation. See contact information and web site in the Resources section of this report. Recombinant human porphobilinogen deaminase rhPBGD or Porphozom was granted orphan drug designation on September 9, , for the treatment of acute intermittent porphyria attacks. This drug is being developed by Zymenex, formerly known as HemeBiotech, a Scandinavian biotechnology company.
Patients are being recruited August for a study to help determine the safety and effectiveness of Porphozom for treatment of acute attacks. The study is being conducted by Dr.
Karl Anderson at the University of Texas in Galveston. Several other products have been granted orphan drug designation by the FDA for the investigational treatment of the porphyrias.
A clinical trial, cosponsored by the National Center for Research Resources and the University of Texas Medical Branch in Galveston, is currently recruiting up to 25 patients. The trial is designed to characterize enzyme defects in patients with known or suspected porphyria and in their family members. RareConnect offers a safe patient-hosted online community for patients and caregivers affected by this rare disease.

About News Events Contact. General Discussion Porphyria is a group of at least eight metabolic disorders that arise as a result of a malfunction in one of the eight steps in the body's synthesis of a complex molecule called heme.
Heme is essential for the transport of oxygen to cells in the body. If any step in the synthesis of heme is blocked, an intermediate chemical accumulates in the cell, resulting in oxygen depletion. Those intermediate chemicals, known as porphyrins or porphyrin precursors, are the substances of which heme is composed. There are two general categories of porphyrias, those that affect the skin and those that affect the nervous system.
The former are called cutaneous porphyrias. Request an Appointment at Mayo Clinic. Autosomal dominant inheritance pattern In an autosomal dominant disorder, the mutated gene is a dominant gene located on one of the nonsex chromosomes autosomes. Autosomal recessive inheritance pattern To have an autosomal recessive disorder, you inherit two mutated genes, one from each parent.
