Clinical Hold on Abeona Gene Therapy

Share

FDA has placed a clinical hold on an Abeona Therapeutics planned Phase 3 clinical trial for EB-101 until it submits “additional data points on transport stability of EB-101 to clinical sites,” according to the company. “Over the last 12 months, the company has worked closely with the FDA to address and narrow open chemical, manufacturing and controls (CMC) items and has been working to resolve this one item identified in the FDA clinical hold letter,” Abeona says. The company expects to receive CMC clearance for VIITAL trial in the fourth quarter.

 

“Looking ahead,” it says, “we believe that completion of our CMC work coupled with the durable safety and efficacy data, now out to five years in some patients, will ultimately be critical to support a future biologics license application.

 

EB-101 is an investigational, autologous, gene-corrected cell therapy for treating recessive dystrophic epidermolysis bullosa, a rare connective tissue disorder without an approved therapy. The disorder, according to the company, is characterized by severe skin wounds that cause pain and can lead to systemic complications impacting the length and quality of life. “Treatment involves using gene transfer to deliver COL7A1 genes into a patient’s own skin cells (keratinocytes) and transplanting them back to the patient to enable normal Type VII collagen expression and facilitate wound healing,” it says.
