TRK-950 is safe and well tolerated, has a favorable PK profile, and should be further investigated as a monotherapy and in combination with standard treatment for various types of solid tumors.
This study demonstrates that radiopharmaceuticals targeting CAPRIN-1, including radiolabeled TRK-950 and TRK-950-F(ab')2, have high potential as radiopharmaceuticals.
Clinical trials (NCT05423262) employing this improved analytical method have been conducted, and the results confirm the low immunogenicity of TRK-950. The combination of pretreatment with Melon™ gel and SPEAD is applicable for clinical ADA assays.
