DateStageInvestorsRaisedDeal Summary
Jun 2026Series BThe Column Group (lead); Samsara BioCapital; Sanofi Ventures; Euclidean Capital$74MNura Bio Inc. completed a $73.8 million Series B financing round led by The Column Group, with participation from Euclidean Capital, Samsara BioCapital, and Sanofi Ventures, to advance its clinical pipeline of neuroprotective SARM1 inhibitor therapies for neurodegenerative diseases including amyotrophic lateral sclerosis (ALS). The funding will support clinical proof-of-biology studies for two pipeline candidates, NB-4746 and NB-9402, with the Phase 1b/2a study of NB-4746 (an oral, brain-penetrant SARM1 inhibitor) recently commencing dosing in ALS patients as the primary near-term catalyst. Nura Bio is a clinical-stage biopharmaceutical company based in South San Francisco, California, comprising a small team of approximately 20 employees, focused on developing small molecule therapies to establish axon protection as a disease-modifying strategy in ALS and other neurodegenerative conditions.
Sep 2024Series AThe Column Group (lead); Samsara BioCapital; Sanofi Ventures; Euclidean Capital$68MNura Bio is a clinical-stage biopharmaceutical company based in South San Francisco, California, focused on developing small molecule neuroprotective therapies to prevent axon degeneration and neuronal loss driven by neuroimmune dysregulation in debilitating neurological diseases such as ALS and MS. The company's lead candidate, NB-4746, a brain-penetrating SARM1 inhibitor, completed Phase 1 testing in healthy volunteers, demonstrating good tolerability, brain penetration confirmed via cerebrospinal fluid measurements, and plans for a proof-of-biology trial in patients in 2025. On September 17, 2024, Nura Bio closed its extended Series A financing round, adding $68 million to the initial $73 million raised in 2020, for a total of over $140 million. The round was led by founding investor The Column Group, with participation from Samsara BioCapital, Euclidean Capital, and new investor Sanofi Ventures. This funding supports advancement of NB-4746 into mid-stage clinical testing, derisking milestones, and progression of its preclinical pipeline targeting axon degeneration and neuroinflammation. Shilpa Sambashivan, Ph.D., a cofounder and former chief scientist, was appointed CEO and board director to lead the transition to clinical-stage development. The company positions itself to address large unmet needs in neurodegeneration, competing with efforts like Eli Lilly's acquisition of Disarm Therapeutics for similar SARM1 inhibitors.
Jul 2020Series AThe Column Group; Samsara BioCapital; Euclidean Capital$73MNura Bio, a biopharmaceutical company based in South San Francisco, California, launched on July 29, 2020, with a $73 million Series A financing round led by The Column Group, alongside Samsara BioCapital and Euclidean Capital. The company focuses on discovering and developing neuroprotective small molecule therapies targeting axonal degeneration and neuroinflammation, early hallmarks of acute and chronic neurological diseases. Its lead program centers on inhibitors of SARM1, an NAD hydrolase identified as a key driver of axon death, with potential applications in central, peripheral, and ocular neurological disorders including multiple sclerosis, traumatic brain injury, chemotherapy-induced peripheral neuropathy, and amyotrophic lateral sclerosis. The funding supports advancement of a multitarget pipeline initially led by a SARM1 inhibitor, enabling Nura Bio to build a leading neuroscience company. Founded in 2018 by The Column Group and scientific founders Marc Freeman, PhD, and Steven McKnight, PhD, the company appointed Alpna Seth, PhD, as President and CEO at launch. In September 2024, Nura Bio extended its Series A with an additional $68 million from the same lead investors plus new participant Sanofi Ventures, bringing total Series A funding to over $140 million. This supported transition to clinical-stage operations, completion of Phase 1 trials for lead candidate NB-4746, and appointment of Shilpa Sambashivan, PhD, as CEO. Plans include initiating Phase 1b/2 trials in 2025.
