Pandion Therapeutics funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Apr 2020 | Series B | Access Biotechnology (lead); Boxer Capital (lead); BioInnovation; JDRF T1D Fund; Roche Venture Fund; Polaris Partners; Versant Ventures; SR One; RA Capital Management; OrbiMed; Mission BioCapital | $80M | Pandion Therapeutics, a Cambridge, Massachusetts-based clinical-stage biotechnology company, closed an $80 million Series B financing round in April 2020 led by Access Biotechnology and Boxer Capital. New investors RA Capital and OrbiMed joined the round, while existing investors including Polaris Partners, Versant Ventures, Roche Venture Fund, SR One, JDRF T1D Fund, and BioInnovation Capital also participated. The financing proceeds were directed toward continued development of Pandion's pipeline of modular proteins and bifunctional antibodies for autoimmune diseases, with particular focus on advancing the lead clinical-stage program PT101, a novel interleukin-2 mutein Fc fusion protein in Phase 1 development, bringing a second program into the clinic, and expanding the company's modular drug design platform. Pandion's lead program, PT101, was designed to activate and expand regulatory T cells in patients with autoimmune diseases. The company had generated human proof-of-mechanism data for PT101 that was instrumental in attracting investor interest. Early clinical results showed PT101 was well-tolerated and triggered its intended targets without activating pro-inflammatory T cells. The company planned Phase 1/2 studies for ulcerative colitis and Phase 2 trials for systemic lupus erythematosus. The company recorded revenue of $2 million for the three months ended March 31, 2020. Pandion had been formed in 2016 and had raised $58 million in a Series A financing in 2018. Following the Series B close, the company went public in July 2020 with an IPO that raised an additional $135 million. The company's trajectory culminated in its acquisition by Merck & Co. for $1.85 billion in February 2021, demonstrating rapid value creation from early-stage clinical success and strong investor backing. In the years leading to the Series B, Pandion had executed strategic partnerships to advance its platform. In October 2019, the company inked a license and collaboration agreement with Astellas Pharma to combine Pandion's modular biologics and functional immunology expertise with Astellas' advanced therapeutics development and commercialization capabilities. In April 2019, Pandion entered a partnership with Twist Bioscience to apply Twist's antibody optimization platform to the targeting arm of a bispecific antibody, further strengthening its modular protein therapeutic capabilities. |
| Jan 2018 | Series A | Polaris Partners (lead); Roche Venture Fund (lead); Versant Ventures (lead); BioInnovation; SR One | $58M | Pandion Therapeutics emerged from stealth in January 2018 with a $58 million Series A financing co-led by Polaris Partners (founding investor), Roche Venture Fund, and Versant Ventures, with participation from SR One and BioInnovation Capital. The Cambridge, Massachusetts-based biotech develops bispecific antibody therapeutics using its proprietary TALON platform to achieve localized immunomodulation for autoimmune and inflammatory diseases, targeting tissues like the gut, liver, kidney, and skin, with initial focus on inflammatory bowel disease, autoimmune liver disease, and plans for type 1 diabetes and skin conditions. The funding supports advancing drug programs to the clinic, building the pipeline, and company expansion, including leadership appointments of CEO Anthony Coyle (ex-Pfizer/MedImmune) and CSO Jo Viney (ex-Biogen). The company's technology draws from immuno-oncology insights to create bispecific antibodies that bind to specific inflammation sites, promoting immune homeostasis rather than broad immunosuppression. Prior to the Series A, Pandion (originally Immunotolerance, formed 2016) received seed funding from Polaris and in December 2017 collaborated with Distributed Bio for antibody discovery using the SuperHuman library, licensing leads and potentially the platform. Post-Series A, Pandion contracted Just Biotherapeutics for development and manufacturing of lead candidate PT101, an IL-2 mutein bispecific antibody entering early clinical trials for ulcerative colitis and systemic lupus erythematosus. Pandion went public in July 2020 (Nasdaq: PAND) and was acquired by Merck in 2021 for $1.85 billion ($60 per share), ending its independent operations after demonstrating clinical proof-of-mechanism with PT101. |
