Aro Biotherapeutics funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Nov 2023 | Series B | Cowen Healthcare Investments (lead); Northpond Ventures; HealthCap; Biotechnology Value Fund; Johnson & Johnson Innovation | $42M | Aro Biotherapeutics, a clinical-stage biotechnology company based in Philadelphia, pioneered the development of tissue-targeted genetic medicines using its proprietary Centyrin protein platform. The platform enables efficient and tissue-specific targeting of small interfering RNA (siRNA) therapies for genetic disorders and autoimmune conditions. On November 28, 2023, Aro announced the closing of a $41.5 million Series B financing round led by Cowen Healthcare Investments, with participation from existing Series A investors including Johnson & Johnson Innovation (JJDC), Northpond Ventures, BVF Partners (Biotechnology Value Fund), and Healthcap. The company's lead program, ABX1100, is a first-in-class Centyrin-siRNA conjugate candidate for Pompe disease, a rare inherited disorder characterized by progressive muscle weakness. ABX1100 had demonstrated a favorable safety profile in preclinical toxicology studies and received both Orphan Drug Designation and Rare Pediatric Disease status from the FDA. The Series B proceeds were designated to advance ABX1100 clinical development, with initial human trial data anticipated in 2024, and to support discovery of new Centyrin-siRNA conjugate therapies for autoimmune disorders. This round came approximately two years after Aro's Series A financing of $88 million in early 2021, which had been led by Northpond Ventures and Cowen Healthcare Investments. |
| Dec 2022 | Series B | Cowen Healthcare Investments (lead) | $24M | Aro Biotherapeutics is a Philadelphia-based clinical-stage biotechnology company developing tissue-targeted genetic medicines using its proprietary Centyrin protein platform for siRNA delivery. The platform enables efficient, tissue-specific targeting for diseases like Pompe Disease and autoimmune disorders. In a Series B financing announced November 28, 2023, Aro raised $41.5 million led by Cowen Healthcare Investments, with participation from existing Series A investors including Johnson & Johnson Innovation – JJDC, Northpond Ventures, Healthcap, and BVF Partners. Christopher Picariello from JJDC joined the board. Funds from the round support advancement of lead program ABX1100, a Centyrin-siRNA conjugate for Pompe Disease, which entered first-in-human trials with initial data expected in 2024. Proceeds also fund discovery of new Centyrin-siRNA programs for autoimmune diseases. The company had previously raised a Series A in 2020 and aggregate funding exceeded $167 million by late 2023 across multiple rounds. Aro's pipeline is wholly-owned, focusing on Centyrins as small, non-antibody scaffolds for multi-specific therapeutics and nucleic acid delivery, aiming for improved efficacy and safety in serious diseases including cancer. |
| Jan 2021 | Series A | Cowen Healthcare Investments (lead); Northpond Ventures (lead); HealthCap; BioMotiv; Biotechnology Value Fund; Ionis Pharmaceuticals; Ridgeback Capital; Johnson & Johnson Innovation | $88M | Aro Biotherapeutics, a Philadelphia-based biotechnology company founded in 2018 by Susan Dillon and Karyn O’Neil, raised $88 million in an oversubscribed Series A financing announced on January 5, 2021. The round was led by Northpond Ventures and Cowen Healthcare Investments, with participation from HealthCap, BVF Partners L.P., Ridgeback Capital, and existing investors including Johnson & Johnson Innovation – JJDC, Inc., BioMotiv, LLC, and Ionis Pharmaceuticals, Inc. Aro pioneers tissue-targeted genetic medicines using its proprietary Centyrin platform, which consists of small, stable engineered human proteins designed to target specific cell receptors and deliver RNA therapeutics like siRNA or antisense oligonucleotides to extra-hepatic tissues. The proceeds were allocated to advance lead Centyrin-conjugated RNA therapeutic candidates into clinical development, initially focusing on rare genetic and immune disorders. Centyrins are one-fifteenth the size of monoclonal antibodies, enabling efficient and precise drug delivery to disease sites. The company plans to leverage the platform for superior efficacy and safety in treating intractable diseases. In parallel, Aro had a collaboration with Ionis Pharmaceuticals, which licensed one program for a rare genetic muscle disease heading into preclinical development in 2021, with potential milestone payments up to $1.4 billion. Subsequent developments include a $41.5 million Series B in November 2023 led by Cowen Healthcare Investments with participation from prior investors to advance ABX1100 for Pompe Disease into phase 1 trials and explore autoimmune programs. |
| Dec 2018 | Series A | BioMotiv (lead); Johnson & Johnson Innovation (lead) | $13M | Aro Biotherapeutics, a biotechnology company co-founded by Sue Dillon and Karyn O’Neil, both former R&D leaders at Janssen Pharmaceutical Companies of Johnson & Johnson, raised $13 million in startup investment on December 11, 2018, from Johnson & Johnson Innovation – JJDC and BioMotiv. The company, based at the University of Pennsylvania’s Pennovation Center in Philadelphia, holds an exclusive worldwide license for Centyrin protein therapeutics discovered by O’Neil’s team at Janssen. Centyrins are small, non-antibody protein therapeutics designed for improved efficacy and safety in treating cancer and other serious diseases, with the lead program targeting non-small cell lung cancer and other applications in development. The funding supports research, development, and commercialization of Centyrins toward clinical development, leveraging production in bacteria like E. coli for cost-effective scaling. Aro established a leadership team with experience in discovery, development, and commercialization of blockbuster biologics for cancer and immune diseases. The company focuses on a wholly-owned pipeline for oncology and immunology, while partnering on Centyrin delivery of drug payloads including nucleic acid drugs. |
