New York-headquartered, the company develops small-molecule inhibitors of KIF18A, a protein essential for cancer cell division in tumors with high chromosomal instability. Its lead candidate, VLS-1488, entered Phase 1 trials in 2022 for ovarian, endometrial, and other cancers. Founded in 2019 by scientists from Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center, Volastra raised $110 million in Series A financing led by Versant Ventures and RA Capital Management.

Volastra Therapeutics funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Sep 2025 | Series A | - | $30M | Volastra Therapeutics is a clinical-stage biotechnology company based in New York, focused on exploiting chromosomal instability (CIN) in cancer cells to develop novel therapies preventing metastasis and targeting chromosomally unstable cancers. Founded by scientists including Lewis Cantley, Olivier Elemento, and Samuel Bakhoum, the company leverages insights into CIN to identify synthetic lethal targets and advance immune-activating pipelines, with lead candidates being KIF18A inhibitors like sovilnesib (formerly AMG650) in Phase 1 trials for platinum-resistant ovarian cancer, triple-negative breast cancer, and other solid tumors with TP53 mutations. The company has raised significant funding across multiple rounds, including a seed extension to $44 million in April 2021 led by Vida Ventures and Catalio Capital Management, alongside Polaris Partners, Droia Ventures, ARCH Venture Partners, and Quark Venture, to build its CIN platform. In March 2023, Volastra closed a $60 million Series A led by Polaris Partners and ARCH Venture Partners with Eli Lilly, Droia Ventures, Catalio, Vida Ventures, Cornell University, and Meyers Ventures, coinciding with an exclusive worldwide license (ex-China) for sovilnesib from Amgen, which included upfront cash/equity, milestones, and royalties; the FDA granted fast-track designation for sovilnesib in ovarian cancer. The company also has a biobucks deal with Bristol Myers Squibb potentially worth over $1 billion. Volastra aims to advance its KIF18A inhibitors through clinical catalysts and expand its pipeline addressing unmet needs in oncology, where metastasis affects over 350,000 U.S. diagnoses annually with low response rates to existing therapies. |
| May 2024 | Series A | - | $15M | Volastra Therapeutics is a clinical-stage biotechnology company developing therapies targeting chromosomal instability (CIN) to prevent and treat metastatic cancer. The company's lead program is sovilnesib (KIF18A inhibitor), which it in-licensed from Amgen in March 2023 and is currently in Phase I/II development for platinum-resistant ovarian cancer and triple-negative breast cancer. On May 30, 2024, Volastra raised $15 million in venture funding from undisclosed investors to advance its drug discovery and therapeutic development efforts. The company had previously secured a $60 million Series A in March 2023 led by Polaris Partners and ARCH Venture Partners, with participation from Eli Lilly and Company and other investors. Volastra's internally discovered KIF18A inhibitor, VLS-1488, received FDA Fast Track designation in October 2024 for ovarian cancer, reflecting the high unmet medical need in this indication. |
| Mar 2023 | Series A | ARCH Venture Partners (lead); Eli Lilly (lead); Polaris Partners (lead); Vida Ventures; Droia Ventures; Cornell University; Catalio Capital Management; Meyer Ventures | $60M | Volastra Therapeutics is a clinical-stage cancer biotechnology company focused on exploiting chromosomal instability (CIN) in oncology. The company closed a $60 million Series A financing round on March 7, 2023, led by founding investors Polaris Partners and ARCH Venture Partners alongside Eli Lilly and Company, with participation from Droia Ventures, Catalio Capital Management, Vida Ventures, Cornell University, and Meyers Ventures LLC. Concurrent with the financing, Volastra in-licensed sovilnesib (AMG650), an oral, first-in-class small molecule inhibitor of KIF18A, from Amgen. Sovilnesib was in Phase 1 testing for the treatment of platinum-resistant high-grade serous ovarian cancer, triple-negative breast cancer, and other solid tumors with TP53 mutations, having received FDA fast-track designation. The financing supported clinical development of Volastra's portfolio of KIF18A inhibitors alongside advancement of research programs targeting chromosomally unstable cancers. In parallel with the Series A, the company had announced a multi-year collaboration with Bristol Myers Squibb valued at up to $1.1 billion focused on drug discovery using CIN-based synthetic lethality approaches, and had partnered with Microsoft to develop artificial intelligence technologies for histopathological identification of chromosomal instability. |
| Apr 2021 | Seed | Catalio Capital Management (lead); Vida Ventures (lead); Droia Ventures; Quark Venture; Polaris Partners; ARCH Venture Partners | $32M | Volastra Therapeutics is a biotech company developing therapies targeting chromosomal instability (CIN) to prevent cancer metastasis, differentiating from primary tumor-focused treatments by addressing metastatic spread where most therapies fail. The company extended its original $12 million seed round by $32 million to a total of $44 million around April 6, 2021 (Seed VC - II), with new investors Catalio Capital Management and Vida Ventures joining existing backers ARCH Venture Partners, Polaris Partners, Droia Ventures, and Quark Venture. A separate $30 million Series A from B Capital Group was noted in 2025, unrelated to the 2021 round. |
| Feb 2020 | Seed | Polaris Partners (lead); Droia Ventures; Quark Venture; GF Securities; Global health sciences venture fund; ARCH Venture Partners | $12M | Volastra Therapeutics, a New York City-based biotechnology company, launched in February 2020 with $12 million in seed financing led by Polaris Partners, with participation from DROIA Oncology Ventures, Global Health Sciences Fund (Quark Venture LP and GF Securities), and ARCH Venture Partners. The company develops novel therapies targeting chromosomal instability, a hallmark of metastatic cancers responsible for approximately 90% of cancer deaths, aiming to shift the treatment paradigm for advanced disease. Executive Chair Sandra Peterson and Polaris Managing Partner Amy Schulman lead the board, with scientific founders represented by Dr. Bakhoum. In April 2021, Volastra extended its seed financing to $44 million, adding Vida Ventures and Catalio Capital Management to advance drug discovery programs to prevent cancer metastasis. By March 2023, the company raised $60 million in Series A funding led by Polaris Partners and ARCH Venture Partners alongside Eli Lilly and Company, while in-licensing Amgen’s sovilnesib (AMG650), a KIF18A inhibitor, to broaden its pipeline. |
