Next Development Steps for IMA402:

The promising clinical profile of IMA402 supports a development path across various solid tumors in earlier and later treatment lines. These include combination approaches with ICIs in melanoma and in gynecologic cancers as well as IMA402 in combination with the Company’s MAGEA4/8-directed bispecific, IMA401, in lung cancer with first data expected in 2027. Furthermore, the use of Immatics’ proprietary rapid, sensitive and reliable liquid biopsy-based PRAME testing enables precise patient selection and could support potential fast-to-market strategies, subject to regulatory approval, in PRAME-high melanoma and beyond.
