Firm Advises Ona Therapeutics on IP Matters Related to $86.6 Million Series B
On June 4, 2026, Ona Therapeutics, a global biopharmaceutical company pioneering first-in-class antibody-drug conjugates (ADCs) to address treatment-resistant cancers, announced the closing of an oversubscribed $86.6 million Series B financing. The round was co-led by new investors Columbus Venture Partners and Mérieux Equity Partners, with participation from additional investors COFIDES and Korys, alongside all existing investors Alta Life Sciences, Asabys Partners, Bpifrance, as part of the InnoBio investment strategy, CDTI through SICC Innvierte, FundPlus NV, and Ysios Capital.

The proceeds from the Series B will be used to advance the clinical development of Ona’s lead program, ONA-255, a first-in-class ADC initially focused on breast cancer, and to progress ONA-389, a second first-in-class ADC targeting colorectal cancer.
