Tempest Therapeutics Inc. has announced details of its pipeline of in vivo CAR T product candidates differentiated by a CD7-targeted mRNA/LNP delivery approach, with application in the fields of oncology and immunology. Tempest’s in vivo CAR T platform, CD7-targeted mRNA lipid nanoparticle (CD7-tLNP), offers broader T-cell reach, enhanced delivery efficiency and scalable in vivo CAR T.

A new strategy based on regulatory T cells (Tregs) engineered with chimeric antigen receptors (CARs) has shown that cell therapies can be directed against soluble allergens to control inflammation. The findings open a potential path toward the development of antigen-specific cell therapies for allergies caused by pollen, food allergens or dust mites.

Fate Therapeutics Inc. has obtained IND clearance from the FDA for FT-839, the company’s next-generation, off-the-shelf CAR T-cell product candidate targeting CD19 and CD38 for autoimmune diseases.
