Immunogen Inc. scored a major win in top-line data from the confirmatory phase III trial called Mirasol evaluating the approved antibody-drug conjugate Elahere (mirvetuximab soravtansine-gynx, “mirv”) vs. chemotherapy in patients with folate receptor alpha-positive platinum-resistant ovarian cancer (PROC). The victory led shares of the Waltham, Mass.-based firm to close May 3 at $12.26, a rise of $7.06, or 135%.
Previous studies have shown that ovarian cancer (OC) has strong tumor heterogeneity, resulting in high recurrence and metastasis rates. In recently published work, researchers from Capital Medical University (CMU) applied single-cell transcriptomics to identify metastasis-associated cell clusters and key genes involved in OC metastasis.
Cadherin 6 (CDH6) is a transmembrane protein with high expression during embryonic kidney development, with very limited expression in adult tissues but overexpressed in several malignancies such as ovarian or renal cancer, and it is tied disease progression and poor prognosis. This pattern of expression makes it an attractive target for antibody-drug conjugate (ADC) development.
Junshi Biosciences Co. Ltd.’s PARP inhibitor, senaparib (JS-109/IMP4297), met the primary endpoint of progression-free survival in a phase III ovarian cancer study, according to a prespecified interim analysis.
Researchers from Astrazeneca plc described the development and preclinical evaluation of AZD-5335, a novel antibody-drug conjugate (ADC) consisting of folate receptor α (FR-α)-targeting antibody conjugated to a proprietary topoisomerase 1 inhibitor (TOP1i), being developed as a potential new therapeutic against ovarian cancer.

Mercy Bioanalytics Inc. stepped into the increasingly competitive early cancer detection field with a $41 million series A financing round to support its Halo liquid biopsy platform. Novalis Lifesciences led the oversubscribed round with participation from Sozo Ventures, Hatteras Venture Partners, Iselect Fund, American Cancer Society BrightEdge and Broadway Angels, an all-women venture capital group. Laboratory Corp. of America Holdings, Bruker Corp. and existing investors also contributed to the round.
