Niagen Bioscience Inc.’s proprietary lead small-molecule drug candidate, NB-4168, has been awarded European orphan drug designation and U.S. rare pediatric disease designation for the treatment of ataxia telangiectasia.

SL Science Holding Ltd. has submitted an orphan drug designation request to the FDA for its γδ T-cell therapy product, Vδ2+ γδ T cells, for the treatment of glioblastoma multiforme.

At the BIO International Convention, nonprofit and for-profit companies discussed ways to fund orphan drug development, especially for ultra-rare diseases where development costs can be challenging. One of the simplest ways to keep costs down is to skip the discovery phase and use repurposed drugs or rescue shelved therapeutic assets as the Orphan Therapeutics Accelerator has done. The Cambridge, Mass.-based accelerator was founded in 2024 to rescue shelled therapeutic assets for ultrarare diseases.
