Disappointing Phase III Hyalofast Trial Results and Impact on FDA Submission Timeline
The U.S. pivotal Phase III trial for Hyalofast missed its primary endpoints, with statistical significance not achieved on co-primary measures of KOOS Pain and IKDC Function.
The trial faced challenges due to declining use of microfracture, higher dropout rates, missed visits during COVID, and reduced evaluable sample size.
Despite the miss on primary endpoints, secondary endpoints showed statistical significance, and international data with positive 15-year outcomes support the product's value.
The company plans to submit the third and final PMA module in the second half of 2025, extending the review timeline to 2027 to ensure thorough review and dialogue with the FDA.
