FDA Accepts Priority Review of Hemophilia B Gene Therapy CSL-uniQure; Fosun Pharma strikes another deal – Endpoints News

The first potential gene therapy for hemophilia B has moved one step closer to patients as the FDA has accepted CSL Behring’s BLA for its unique treatment in partnership with uniQure. The therapy, called etranacogen dezaparvovec, has been accepted under “accelerated review” by the European Medicines Agency in March.

A priority review will be done for gene therapy for patients with the inherited bleeding disorder, CSL said Tuesday morning. The Pennsylvania biotech did not provide a date for the regulator’s decision, but priority review usually means the treatment will be decided within six months instead of 10.

Regulators will base their decision on a Phase III study that found the treatment is not inferior to baseline factor IX prophylactic therapy on annualized bleeding rate (ABR) after 18 months. The companies said the treatment was also statistically superior in reducing ABR after 18 months in the HOPE-B study.

This is good news for patients and companies after a five-month suspension last year due to a safety issue that revealed a patient in the study had developed liver cancer. UniQure concluded that its therapy was “highly unlikely” to have led to the cancer.

SVB Securities analysts said they expect a decision from the EMA in the third quarter and from the FDA in the following quarter. Analysts said the gene therapy has “compelling endorsement potential that could rekindle interest in the broader gene therapy space,” noting that another key decision will be in hemophilia gene therapy. A from BioMarin, which is under review in Europe and provided for a new submission in June in the United States.

Meanwhile, Cowen analysts noted that in their survey of estimated use of hemophilia B gene therapy, doctors said 13% of patients would use such treatment three years after launch, while payers expected 31% to do so.

Analysts have estimated peak worldwide sales at $1.2 billion, with uniQure potentially earning $485 million in peak royalties after selling exclusive worldwide rights to CSL in a $2 billion pact. — Kyle LaHucik
