The US Food and Drug Administration (FDA) has granted the complement inhibitor AMY-101 orphan status as a treatment for paroxysmal nocturnal
hemoglobinuria (PNH).
Roughly 2 months ago, the European Medicines Agency (EMA) did the same.
Orphan designation will allow Amyndas Pharmaceuticals, the company developing AMY-101, to proceed with expedited clinical development. The company is
planning to move the drug into clinical trials in 2015.
If AMY-101 is approved by the FDA, orphan status will allow for a 7-year period of market exclusivity from product launch in the US. It will also allow Amyndas to apply for research funding, tax credits for certain research expenses, and assistance for clinical research study design. It provides a waiver from the FDA’s Prescription Drug User Fee as well.
“Receiving the orphan drug designation from both the FDA and the EMA is an important achievement and a key milestone in the development pathway of AMY-101, and we are optimistic regarding the long-term potential of this potent complement inhibitor,” said John Lambris, PhD, of the University of Pennsylvania.
Dr Lambris developed AMY-101 at the University of Pennsylvania, and the university licensed the drug to Amyndas Pharmaceuticals. Dr Lambris is a founder and equity holder of Amyndas Pharmaceuticals.
About AMY-101 and PNH
PNH is caused by the defective expression of regulatory proteins on the surface of blood cells, which leaves them vulnerable to complement attack. This can lead to hemolysis, which results in severe anemia and contributes to a high risk of thrombosis.
The monoclonal antibody eculizumab is often successful in treating PNH, but roughly a third of patients do not respond well to the drug and still require blood transfusions to manage their anemia.
Research has suggested this lack of response is due to fragments of complement C3 proteins on the surface of the patients’ red blood cells, which are eventually attacked by immune cells.
In an attempt to overcome this problem, Dr Lambris and his colleagues developed AMY-101. The drug is designed to inhibit C3, thereby preventing hemolysis and immune cell recognition.
The researchers have investigated the effects of AMY-101 on self-attack and the resulting hemolysis in human PNH cells and found the drug to be active.
These results have not been published, but the group has published results with a C3 inhibitor known as Cp40, and AMY-101 is based on Cp40.
The researchers reported in Blood that Cp40 and its long-acting form, PEG-Cp40, effectively inhibited hemolysis and efficiently prevented the deposition of C3 fragments on red blood cells from patients with PNH.
