HISTOGENICS AND FDA CONTINUE TO DISCUSS NEOCART^® PHASE 3 CLINICAL TRIAL DATA AND POTENTIAL REGULATORY PATHWAY

WALTHAM, Mass., November 29, 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 its ongoing dialogue with the U.S. Food and Drug Administration (the FDA). Since the initial Type C meeting in October 2018, Histogenics and the FDA have continued their discussions on 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 NeoCart Biologics License Application (BLA). The FDA has not yet made a final decision regarding a potential BLA submission. Histogenics intends to provide a further update by the end of 2018 or early 2019 based on additional feedback from the FDA, once available.

“We very much appreciate the FDA’s consideration and active review of our request to evaluate the existing Phase 3 clinical data for a potential NeoCart BLA submission. We continue to work very closely with the FDA to review the data from the NeoCart development program. Our discussions have covered many areas including the clinical data, patient population and related statistics from the NeoCart Phase 3 clinical trial, potential alternative pathways for the BLA as well as the current treatment paradigms for knee cartilage defects in relation to the design of the NeoCart Phase 3 clinical trial,” said Adam Gridley, President and Chief Executive Officer of Histogenics. “We continue to believe, based on the totality of the data, that NeoCart, if the BLA were accepted and approved by the FDA, may offer patients a treatment alternative that provides a more rapid recovery from pain and return to daily activity than other currently available options to treat damaged knee cartilage.”

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. Histogenics’ technology platform has the potential to be used for a broad range of additional restorative cell therapy indications.
