The U.S. FDA issued the CRL to Lilly regarding the BLA for mirikizumab, a humanized IgG4 monoclonal antibody to treat ulcerative colitis, specifically citing manufacturing concerns. There’s a similar problem with Alvotech’s biosimilar candidate for Abbvie Inc.’s Humira (adalimumab). The FDA issued a CRL for AVT-02’s BLA, citing problems needing resolution at its Reykjavik, Iceland, manufacturing facility before it could approve the application.

The possibilities of cures for cancer and other tough-to-treat diseases and the ability to further personalize medicine are creating a lot of excitement about the future of radiopharmaceuticals as both therapy and diagnostics. To reach that future, industry and researchers will have to overcome a lot of challenges, not the least of which stem from the multiple government agencies involved in regulating the source material, development, distribution and use of radioactive drugs and devices.
Promis Neurosciences Inc. has submitted an IND application to the FDA for PMN-310 for the treatment of Alzheimer’s disease.
