DateStageInvestorsRaisedDeal Summary
Dec 2022Undisclosed stagePfizer Venture Investments (lead)$25MRibon Therapeutics is a clinical-stage biotechnology company developing oral small molecule therapeutics that target stress support pathways. The company's lead programs include RBN-2397, a potentially first-in-class PARP7 inhibitor for oncology, and RBN-3143, a PARP14 inhibitor for immunology and inflammatory diseases. Both programs are derived from Ribon's proprietary BEACON+ platform. In January 2023, Pfizer Ventures announced a $25 million equity investment in Ribon to support clinical development of these lead programs and advance early-stage pipeline candidates. As part of the investment, Robert Rickert, Ph.D., Senior Vice President and Head of Cancer Immunology Discovery at Pfizer, joined Ribon's Scientific Advisory Board, providing both capital and scientific expertise to the company's drug development efforts. The company targets novel enzyme families that are activated under cellular stress conditions and contribute to disease pathology, focusing on patient populations with limited therapeutic options in oncology and inflammatory disease areas.
Jun 2021Series CDeerfield (lead); U.S. Venture Partners (lead)$65MRibon Therapeutics, a clinical-stage biotechnology company based in Cambridge, Massachusetts, develops small-molecule therapeutics targeting stress support pathways in cancer and inflammation using its proprietary BEACON+ platform, which identifies inhibitors of NAD+-utilizing enzymes. The company announced the closing of a $65 million financing on July 14, 2021, led by Deerfield Management and U.S. Venture Partners, with participation from new investors Avego BioScience Capital, GV (formerly Google Ventures), Monashee Investment Management, and Peregrine Ventures, as well as existing investors including AbbVie Ventures, Bristol Myers Squibb, Euclidean Capital, Johnson & Johnson Innovation – JJDC, Inc., Novartis Venture Fund, Osage University Partners, Takeda Ventures, and The Column Group. Proceeds from the round are designated to advance lead product candidates RBN-2397, a PARP7 inhibitor in Phase I clinical trials for solid tumors (with plans to combine it with Merck's Keytruda), and RBN-3143, a PARP14 inhibitor in preclinical development for inflammatory diseases targeting the IL4 signaling pathway, through key clinical milestones, while also supporting additional drug discovery and validation efforts. At the time, Ribon had presented Phase I data for RBN-2397 at the American Society of Clinical Oncology meeting. CEO Victoria Richon highlighted the funding's role in enabling development of novel precision drugs. Deerfield's Cameron Wheeler, a board director, emphasized Ribon's progress in pioneering first-in-class candidates and the commitment to its science foundation for clinical, preclinical, and platform execution.

Oct 2017Undisclosed stage-$20MRibon Therapeutics is a biotechnology company developing therapeutics targeting stress support pathways in cancer and inflammation, focusing on enzyme families activated under cellular stress conditions, including PARP7 inhibitors for diseases like squamous cell lung cancer. The company emerged from stealth with prior funding rounds including $23.5 million in 2016 and $20 million in October 2017, led by investors such as Novartis Venture Fund, Johnson & Johnson Innovation – JJDC, Takeda Ventures, Celgene, Osage University Partners, The Column Group, Deerfield Management, and US Venture Partners. These early rounds supported foundational research stemming from institutions like MIT, UT Southwestern Medical Centre, and Harvard Medical School. The $20 million round in October 2017 contributed to Ribon Therapeutics' overall funding exceeding $108 million at the time, positioning it to advance its pipeline of precision medicine candidates targeting monoPARP enzymes that help cancer cells regulate stress responses and evade immune detection. Subsequently, Ribon raised a $65 million Series B in January 2019 (with announcements in 2021), led by Deerfield Management and U.S. Venture Partners, with participation from new and existing investors including Avego BioScience Capital, GV, AbbVie Ventures, Bristol Myers Squibb, and others. This funding advanced lead candidates RBN-2397 (cancer) and RBN-3143 (inflammation) into clinical stages, building on the earlier 2017 capital. The company's traction includes preclinical progress and later Phase 1 data showing partial responses in solid tumors.
