Develops in vivo and autologous CAR-T candidates alongside oncology small molecules, with near-term emphasis on a CD7-targeted mRNA/lipid-nanoparticle platform. Programs generate no product revenue and advance through partners, external trials, and third-party manufacturing.
Advances a cell-therapy and small-molecule portfolio for autoimmune disease, cancer, and selected oncology indications. Its in vivo CAR-T platform is led by TPST-4003, which uses CD7-targeted mRNA/lipid-nanoparticle delivery and a dual CD19/BCMA CAR design; separate programs address non-B-cell blood cancers and solid tumors.
Also holds a clinical-stage autologous CAR-T candidate for multiple myeloma and POEMS syndrome, amezalpat for hepatocellular carcinoma, and TPST-1495 for familial adenomatous polyposis. Amezalpat's next-stage study requires a partnership or separate funding, while TPST-1495 is planned through an NCI-supported trial network.
Runs one discovery-and-development segment with no approved products or product-sale revenue. Its small workforce and lack of owned manufacturing make execution dependent on partners, contractors, externally supported trials, regulatory acceptance, and financing.
