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.

While U.S. politics continues to delay Senate confirmation of the NIH director, other crucial positions at the agency that don’t require Senate action are being filled. Acting NIH Director Lawrence Tabak announced Aug. 2 that he has named Jeanne Marrazzo as director of the agency’s National Institute of Allergy and Infectious Diseases (NIAID).

The old adage of “what goes up must come down” rarely applies to U.S. FDA user fees. Most of the fiscal 2024 fees, which go into effect Oct. 1, continue in an upward slope. Under the PDUFA agreement, the fees for NDAs/BLAs are surging 25%. All but one of the MDUFA fees are going up 9.5%; the lone exception is growing by 18%. The MDUFA hikes are building on top of this year’s hefty increases. In the generics realm, the drug master file fee is going up 21%, but other fees increases are in the single digit range. Biosimilars, however, are the exception to the rule, with all the BsUFA fees seeing big drops.

China’s National Medical Products Administration (NMPA) accepted Luye Pharma Group Ltd.’s NDA for rotigotine (LY-03003) extended-release microspheres and granted it priority review for treating Parkinson’s disease. The microsphere formulation delivers the dopamine agonist in a weekly injection. If approved, LY-03003 would be the first long-acting extended-release microsphere formulation for the treatment of Parkinson’s disease (PD). The drug is also being developed in parallel in the U.S. and Japan.

Both China’s NMPA and the U.S. FDA recently approved the IND applications for a phase I trial of Leads Biolabs’ LBL-034 to treat relapsed or refractory multiple myeloma. The Taiwan FDA also approved Hanchorbio Inc.’s IND application to start a multiregional phase I trial for HCB-101 for advanced solid tumors, and the China Center for Drug Evaluation cleared a phase II trial for Suzhou, China-based Transcenta Holding Ltd.’s TST-002 (blosozumab) for osteoporosis and conditions of reduced bone mineral density. In addition, the NMPA approved Shanghai-based Everest Medicines Ltd.’s application for an extended, post-approval study on Nefecon (targeted-release formulation-budesonide) to treat IgA nephropathy.
