What did Mesoblast announce?
Investors are snapping up Mesoblast shares after the company provided a regulatory update on the appropriate potency assay on remestemcel-L.
According to the release, the company held discussions with US Food and Drug Administration's Office of Tissues and Advanced Therapies (OTAT) in response to the received complete response letter (CRL).
As such, Mesoblast requested to explore the potency assay and chemistry, manufacturing and controls (CMC) items for remestemcel-L.
The OTAT advised that the company's approach to addressing the outstanding CMC items is a reasonable critical quality attribute (CQA). OTAT also noted that the relevance of this activity to clinical outcomes should be established.
Mesoblast stated that it has generated substantial data that it believes meets the proposed in vitro immunomodulatory activity of remestemcel-L. This is demonstrated in its phase III trial in children with steroid-refractory acute graft versus host disease (SR-aGVHD).
The company will present its findings to the OTAT, and address other remaining CRL items as required, for the Biologics License Application resubmission.
