Clinical Trials

Multiple clinical trials evaluate the selective KIF18A inhibitor Sovilnesib across early-phase oncology studies, specifically Phase I and Phase Ib investigations sponsored by industry partners such as Volastra Therapeutics and Amgen. These dose-exploration and dose-optimization studies focus on subjects presenting with advanced solid tumors, high-grade serous ovarian adenocarcinoma, fallopian tube cancer, primary peritoneal carcinoma, and cancers characterized by chromosomal instability. Encompassing completed, recruiting, and active, not recruiting stages, several clinical trials aim to assess the compound's safety, pharmacokinetics, and clinical efficacy.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Sovilnesib selectively binds to and inhibits the kinesin-like protein KIF18A, thereby disrupting mitotic spindle assembly and chromosome alignment during cell division. This persistent mitotic impairment induces prolonged cell cycle arrest and selective apoptosis in tumor cells exhibiting chromosomal instability, offering target-directed anti-neoplastic activity for clinical indications such as high-grade serous ovarian cancer and advanced solid tumors.
