Read MoreHide Full Article

bluebird bio, Inc. (BLUE - Free Report) announced that the FDA has accepted the biologics license application (BLA) for its gene therapy lovotibeglogene autotemcel (lovo-cel) for priority review.

The regulatory body has set a target action date of Dec 20, 2023.

Lovo-cel is a potentially transformative, one-time gene therapy for individuals with sickle cell disease (SCD) ages 12 and older who have a history of vaso-occlusive events (VOEs).  

The FDA generally grants Priority Review to therapies that are likely to provide significant improvements in the treatment, diagnosis or prevention of serious conditions. The designation comes with various benefits, like a review timeline of six months from the time of filing compared with a standard review timeline of 10 months.

The BLA for lovo-cel is based on efficacy results from 36 patients in the HGB-206 study Group C cohort with a median 32 months of follow-up and two patients in the HGB-210 study with 18 months of follow-up each. The BLA submission also includes safety data from 50 patients treated across the entire lovo-cel program, including six patients with six or more years of follow-up, which is the longest follow-up of any gene therapy program for SCD.

A potential approval will make lovo-cel – bluebird’s third ex-vivo gene therapy approved by the FDA for a rare genetic disease and its second FDA approval for an inherited hemoglobin disorder.

The FDA previously granted orphan drug designation, fast track designation, regenerative medicine advanced therapy (RMAT) designation and rare pediatric disease designation to lovo cell.

Shares of BLUE have plunged 50.7% so far this year compared with the industry’s 7.7% decline.
