Journal: HER2 and FOLR1 Expression in Mesonephric and Mesonephric-Like Adenocarcinomas in the Gynecologic Tract. (Pubmed Central) - May 7, 2026 FOLR1 met current MIRV treatment criteria in one case, while ten others showed expression ranging from 5% to 70%. Although most tumors did not meet current biomarker thresholds for Trastuzumab or MIRV monotherapy, detectable expression supports exploring anti-HER2 T-Dxd and MIRV combination treatments in selected MA/MLA cases.

Journal, Tumor mutational burden, IO biomarker: Characterizing therapeutic target antigen expression in anaplastic carcinoma of the ovary. (Pubmed Central) - Apr 9, 2026 FOLR1 expression in the two cases was weak and below currently used clinical cutoffs for mirvetuximab soravtansine eligibility...Only a subset of anaplastic carcinomas of the ovary express targetable tumor antigens at low levels, suggesting that these may have limited benefit from antibody-drug conjugates. Likewise, due to mismatch repair proficiency and low tumor mutational burden, immunotherapy is unlikely to be effective in this rare disease.

A Novel FOLR1 and TRAIL-R2 targeting bispecific antibody to treat ovarian cancer (Section 20) - Mar 17, 2026 - Abstract #AACR2026AACR_7782; This study reveals a previously unappreciated mechanism in antibody therapeutics: the use of a tumor-enriched anchor (FOLR1) to optimize death receptor clustering and activation, enabling a quantum leap in apoptotic signaling and therapeutic index for ovarian cancer. The TRAILBody platform thus offers a foundation for next-generation immuno-oncology agents and revives hope for the clinical translation of death receptor agonism, particularly in solid tumors marked by immune exclusion and therapeutic resistance.
