FDA grants Avatrombopag Orphan Drug Designation for thrombocytopenia

The US FDA has granted avatrombopag (Doptelet) ODD as around 10 percent of US cancer patients per year experience chemotherapy-induced thrombocytopenia (CIT) with no available treatment.

The US Food and Drug Administration (FDA) has granted avatrombopag (Doptelet) Orphan Drug Designation (ODD) for the potential treatment of chemotherapy-induced thrombocytopenia (CIT). Enrolment for the Phase III clinical trial for avatrombopag as a treatment of CIT is ongoing.

CIT results in low platelet levels; patients with CIT frequently require chemotherapy dose reductions or delays and or chemotherapy regimen changes. As a result, these patients may have compromised long-term outcomes from their treatments.

“CIT is a potentially serious complication of chemotherapy with no available treatments.  The granting of ODD highlights the significant need for a drug that could improve chemotherapy-induced low platelet counts and thereby enable patients to better adhere to their chemotherapy regimen,” said Mahmood Ladha, President and Head of Dova Pharmaceuticals Inc.

Doptelet is an oral thrombopoietin (TPO) receptor agonist administered with food. It is already FDA approved for the treatment of:

Chronic ITP is a rare autoimmune bleeding disorder characterised by low number of platelets, affecting approximately 60,000 adults in the US.
