Synthekine funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Jan 2023 | Series C | The Column Group (lead) | $100M | Synthekine is an engineered cytokine therapeutics company developing selective cytokine therapies for cancer and inflammatory diseases using three distinct cytokine engineering platforms. Founded in 2019 and headquartered in Menlo Park, California, Synthekine has progressed significantly since inception, advancing STK-012 into the clinic, developing cytokine approaches to enhance CAR-T therapies, and securing a pharmaceutical partnership with Merck. The company closed a $100 million Series C financing on January 6, 2023, led by The Column Group with participation from new and existing investors. Proceeds will advance the pipeline, including Phase 1 trial for alpha/beta-biased IL-2 partial agonist STK-012, upcoming clinical studies for orthogonal IL-2 and CD19 CAR-T combination STK-009 + SYNCAR-001, and IND-enabling studies for IL-12 partial agonist. Prior to Series C, the company raised $107.5 million in an oversubscribed Series B in June 2021 co-led by Deerfield Management and Janus Henderson Investors, with participation from RA Capital Management, Rock Springs Capital, Omega Funds, and others including The Column Group. Synthekine continued pipeline development post-Series C, receiving FDA Fast Track designation in January 2023 for SYNCAR-001 + STK-009 in refractory systemic lupus erythematosus without lymphodepletion. |
| Jun 2021 | Series B | Deerfield (lead); Janus Henderson (lead); TCG Crossover; Emerson Collective; The Column Group; Canaan Partners; Rock Springs Capital; Omega Funds; RA Capital Management; Lilly Asia Ventures; Samsara BioCapital | $108M | Synthekine Inc. is an engineered cytokine therapeutics company based in Menlo Park, California, founded in 2019 from the lab of K. Christopher Garcia at Stanford University. The company develops selective cytokine therapeutics to treat cancer and inflammatory diseases using proprietary cytokine engineering platforms, focusing on partial agonists to avoid toxicities like vascular leak syndrome associated with traditional IL-2 therapies. On June 10, 2021, Synthekine closed an oversubscribed $107.5 million Series B financing round co-led by Deerfield Management and Janus Henderson Investors. New investors included RA Capital Management, Rock Springs Capital, Omega Funds, TCG X (also referred to as TCG Crossover), Lilly Asia Ventures, and an undisclosed healthcare investor. Existing Series A investors such as The Column Group, Samsara BioCapital, Canaan Partners, and Emerson Collective also participated, matching the specified investor list. Proceeds from the round are designated to advance lead programs to clinical proof-of-concept, including selective IL-2 partial agonist STK-012 and the orthogonal IL-2/CD19 CAR-T system (STK-009 and SYNCAR-001), with plans to initiate clinical trials within 12 months. The funding will also support preclinical pipeline expansion for IL-10, IL-12, and IL-22 partial agonists and further platform maturation. At the time of the Series B, Synthekine had no clinical-stage programs and was advancing from IND-enabling studies, with preclinical data presented at AACR showing STK-012's anti-tumor activity without key IL-2 toxicities. The company launched publicly in September 2020 with $82 million in Series A funding, bringing total funding to approximately $190 million post-Series B. |
| Sep 2020 | Series A | Canaan Partners (lead); Samsara BioCapital (lead); The Column Group (lead) | $82M | Synthekine Inc., an engineered cytokine therapeutics company founded by K. Christopher Garcia, Ph.D., launched on September 17, 2020, with an $82 million Series A financing co-led by Canaan Partners, Samsara BioCapital, and The Column Group, with participation from undisclosed investors. The foundational research into cytokine structural biology and immune function was licensed from Stanford University. The company combines immunology, structural insights, and engineering technologies to develop optimized cytokine therapeutics for cancer and autoimmune diseases. Proceeds from the Series A will advance Synthekine’s lead programs into clinical studies, expand its discovery pipeline, and refine proprietary cytokine engineering platforms. Key preclinical programs include STK-012, an engineered IL-2 partial agonist for cancer treatment, and a combination of STK-009 (orthogonal IL-2 ligand) with SYNCAR-001 (CD19 CAR-T cell therapy). The company aims to overcome challenges with native cytokines, which broadly activate immune cells and cause side effects, by tuning them for selective therapeutic effects. Synthekine’s board includes founding members Tim Kutzkey (The Column Group), Srinivas Akkaraju (Samsara BioCapital), and Julie Grant (Canaan Partners), with biopharma veteran Nils Lonberg added as an independent director. Headquartered in Menlo Park, California, the company has since raised additional rounds, including a Series B of $107.5 million in June 2021 and a Series C of $100 million in January 2023, bringing total funding to approximately $289.5 million across three rounds as of early 2023. |
