CLINICAL TRIAL DATA AND POTENTIAL REGULATORY PATHWAY

WALTHAM, Mass., November 1, 2018 /GLOBE NEWSWIRE/ – Histogenics Corporation (Histogenics) (Nasdaq: HSGX), a leader in the development of restorative cell therapies that may offer rapid-onset pain relief and restored function, today provided an update on the NeoCart regulatory pathway based on preliminary feedback from the Type C meeting held with the U.S. Food and Drug Administration (the FDA) on October 30, 2018. At the meeting, thetop-line results from the NeoCart Phase 3 clinical trial and the potential for the submission of a Biologics License Application (BLA) were discussed. Following the meeting, the FDA and Histogenics continue to discuss the clinical data generated to date, the potential need for any additional supplemental clinical data (which may include longer-term data from the ongoing Phase 3 trial or additional studies) and potential alternative regulatory pathways for the BLA to be accepted. The FDA has not made a final decision regarding a potential BLA submission and based on expected feedback from the FDA, Histogenics intends to provide a further update on these negotiations by the end of November 2018.

About Histogenics Corporation

Histogenics (Nasdaq: HSGX) is a leader in the development of restorative cell therapies that may offer rapid-onset pain relief and restored function. Histogenics’ lead investigational product, NeoCart, is designed to rebuild a patient’s own knee cartilage to treat pain at the source and potentially prevent a patient’s progression to osteoarthritis. NeoCart is one of the most rigorously studied restorative cell therapies for orthopedic use. NeoCart is designed to perform like articular hyaline cartilage at the time of treatment, and as a result, may provide patients with more rapid pain relief and accelerated recovery as compared to the current standard of care.
