The company's portfolio focuses on mitochondrial protonophores, with lead programs including TLC-6740, TLC-1180, and TLC-1235 advancing toward later-stage clinical trials and IND-enabling studies. Additionally, OrsoBio is developing TLC-3595, an ACC2 inhibitor in Phase 2a for type 2 diabetes, and TLC-2716, an LXR inverse agonist in Phase 2a for severe hypertriglyceridemia and MASH. In September 2024, OrsoBio closed an oversubscribed $67 million Series B financing round co-led by Ascenta Capital and Woodline Partners LP, with significant participation from existing investors including Samsara Biocapital, Longitude Capital, Enavate Sciences, NuevaBio, and Eli Lilly and Company. Evan Rachlin, MD, Co-Founder and Managing Partner of Ascenta Capital, joined OrsoBio's Board of Directors in conjunction with the financing. The capital is designated to accelerate development of the company's mitochondrial protonophore portfolio for obesity and associated metabolic disorders, with CEO Mani Subramanian emphasizing the company's vision of protonophores as components of future GLP-1 RA-based combination therapies. |
| Nov 2023 | Series A | Enavate Sciences (lead); Longitude Capital (lead); NuevaBio; Eli Lilly; Samsara BioCapital | $60M | OrsoBio, Inc. is a clinical-stage biopharmaceutical company developing oral small-molecule therapies targeting core pathways of energy metabolism to treat obesity and associated metabolic disorders, including type 2 diabetes, MASH, and severe hypertriglyceridemia. Its portfolio includes TLC-6740 (oral liver-targeted mitochondrial protonophore in Phase 1b for obesity), TLC-1180 and TLC-1235 (long-acting and controlled-release protonophores), TLC-3595 (ACC2 inhibitor in Phase 2a for type 2 diabetes), and TLC-2716 (LXR inverse agonist in Phase 2a for SHTG/NASH). On November 7, 2023, OrsoBio announced a $60 million Series A financing co-led by Longitude Capital and Enavate Sciences, with participation from existing investors Samsara BioCapital and NuevaBio, and new investor Eli Lilly and Company. This brought total capital raised to $97 million, following prior seed funding. The proceeds support advancement of its obesity-focused portfolio, including completing Phase 2a trials for LXR inverse agonist and ACC2 inhibitor, Phase 1b for mitochondrial protonophore, and IND-enabling activities for other programs. Matthew Young of Longitude Capital and Edd Fleming of Enavate Sciences joined the board. A later Series B round of $67M was raised around September 2024, co-led by Ascenta Capital and Woodline Partners, with participation from existing investors including those in the Series A. Aggregate funding reached approximately $166M by 2026. The company positions its therapies as complementary oral alternatives to injectable GLP-1 agonists like Ozempic, focusing on mitochondrial uncoupling and other metabolic targets. Peak sales estimates from analysts reach $5.5B for lead programs, though these are speculative. |
