Rallybio Funding Rounds

DateStageRaised FromRaisedValuationRev. MultipleDeal Summary
Apr-20Series BPivotal bioVenture Partners$145MRallybio, a biopharmaceutical company focused on developing therapies for severe and rare disorders, completed a $145 million Series B financing round in April 2020 led by Pivotal bioVenture Partners. New investors included Viking Global Investors, TPG’s The Rise Fund, F-Prime Capital, funds managed by Tekla Capital Management LLC, Solasta Ventures, Fairview Capital, and Mitsui & Co. Global Investment Inc., with participation from existing investors 5AM Ventures, Canaan Partners, New Leaf Venture Partners, and Connecticut Innovations. Proceeds from the financing were allocated to advance Rallybio’s pipeline of product candidates targeting devastating rare diseases, particularly its lead program RLYB211 for preventing fetal and neonatal alloimmune thrombocytopenia (FNAIT), a rare condition causing uncontrolled bleeding in fetuses and newborns. RLYB211 had received Orphan Drug designation from the FDA and EMA, as well as Rare Pediatric Disease designation from the FDA. The funds also supported preclinical candidates for a rare hematologic disease, rare immuno-inflammatory diseases, and a discovery-stage program for a rare metabolic disease in a joint venture with Exscentia, plus portfolio expansion. The round highlighted Rallybio's experienced leadership and robust pipeline, with Pivotal bioVenture Partners' Managing Partner Rob Hopfner praising the team's potential to transform rare diseases.
Apr-18Series A5AM Ventures; Canaan Partners; Connecticut Innovations; New Leaf Venture Partners$37MRallybio, a biotechnology company focused on developing transformative therapies for severe and rare disorders, was co-founded in January 2018 by former Alexion executives Martin Mackay, Stephen Uden, and Jeffrey Fryer. The company raised $37 million in its Series A funding round on April 25, 2018, led by 5AM Ventures with participation from Canaan Partners, New Leaf Venture Partners, and Connecticut Innovations. This inaugural financing supported the launch of Rallybio, which aimed to accelerate breakthrough treatments using an agnostic approach across disease areas, avoiding high-risk internal development costs for large pharma. Rallybio positioned itself to address unmet needs in rare diseases, leveraging the founders' experience with complement inhibitors like Soliris and Ultomiris. The Series A provided initial capital to identify and advance assets. Subsequently, Rallybio raised a $145 million Series B in 2020 from investors including Canaan Partners, 5AM Ventures, F-Prime Capital, and Viking Global Investors, unveiling lead program RLYB-211 for fetal and neonatal alloimmune thrombocytopenia (FNAIT), a condition causing fetal bleeding with no existing treatments. The Series B funded a phase 1/2 study for RLYB-211, preclinical advancement of RLYB-212 for a rare blood disorder, and other immune-inflammatory programs. Later developments included preclinical collaborations, asset sales like a $20 million JV deal in 2025, and a 2025 merger with Candid Therapeutics involving $505.5 million financing, shifting focus to autoimmune T-cell engagers while legacy assets like RLYB116 (C5 inhibitor) moved to contingent value rights.
