Aug. 4, 2023
By Tamra Sami
Regenerative medicine company Mesoblast Ltd.’s stock sank nearly 57% on the news that it received a second U.S. FDA complete response letter (CRL) following the resubmission of its BLA for allogeneic stem cell treatment remestemcel-L in children with steroid-refractory acute graft-vs.-host disease. In the CRL, issued a few days after the Aug. 2 PDUFA date, the agency said it requires more data to support approval.

Immunitybio’s bladder cancer candidate hit with a CRL

May 11, 2023
By Lee Landenberger
The U.S. FDA issued a complete response letter regarding the BLA for Immunitybio Inc.’s bladder cancer treatment, N-803 (Anktiva), halting the drug’s development and slicing the stock value in half.

March 14, 2023
By Tamra Sami
The U.S. FDA has accepted Mesoblast Ltd.’s BLA resubmission for its allogeneic stem cell treatment remestemcel-L in children with steroid-refractory acute graft-vs.-host disease (SR-aGVHD).
