Aspen Neuroscience funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Nov 2025 | Series C | ARCH Venture Partners (lead); Frazier Life Sciences (lead); OrbiMed (lead); Revelation Partners (lead) | $115M | Aspen Neuroscience, a San Diego-based clinical-stage biotechnology company, develops autologous regenerative therapies using patient-derived induced pluripotent stem cells (iPSCs) for neurodegenerative diseases, with its lead program ANPD001 targeting moderate to advanced Parkinson’s disease. ANPD001 is an investigational autologous dopaminergic neuronal precursor cell therapy that reprograms patients’ skin cells into neurons transplanted into the brain, currently in a phase 1/2 clinical trial with FDA Fast Track designation. The company’s platform integrates machine learning and advanced genomics for personalized cell production. On November 20, 2025, Aspen closed a $115 million Series C financing round co-led by ARCH Venture Partners, Frazier Life Sciences, OrbiMed, and Revelation Partners, matching the specified investors. Participation came from existing investors like Medical Excellence Capital, S32, Axon Ventures, LYFE Capital, and LifeForce Capital, plus new investors including Kite (a Gilead Company), Balyasny Asset Management, Cormorant Asset Management, and Prebys Ventures. This round brings Aspen’s total capital raised to over $340 million, including prior rounds ($70 million Series A in 2020, $147.5 million Series B in 2022) and an $8 million grant from the California Institute for Regenerative Medicine. Proceeds will support ongoing ANPD001 clinical trials, scale manufacturing for clinical and commercial needs, and advance the pipeline of iPSC-derived therapies for additional neurological indications. CEO Damien McDevitt highlighted the funding’s role in accelerating clinical development, operations scaling, and commercial readiness. The company is well-funded, considering future options like IPO or partnerships to advance its programs. Aspen positions itself in the competitive cell therapy space for Parkinson’s, emphasizing personalized autologous approaches over allogeneic alternatives. |
| May 2022 | Series B | GV (lead); LYFE Capital (lead); Revelation Partners (lead) | $148M | Aspen Neuroscience is a clinical-stage biotechnology company developing autologous cell therapies, with a focus on iPSC-derived autologous neuron replacement treatment for Parkinson's disease. The company's lead program, ANPD001, is designed for moderate to advanced Parkinson's disease and represents a potentially disease-modifying therapy approach. In early 2022, Aspen closed a $147.5 million Series B financing round co-led by GV (Google Ventures), LYFE Capital, and Revelation Partners, with participation from Newton Investment Management, Singapore-based EDBI, LifeForce Capital, Medical Excellence Capital Partners, Mirae Asset Capital, NS Investment, and returning investors ARCH Venture Partners, OrbiMed Private Investments, Frazier Healthcare Partners, Alexandria Venture Investments, and Section 32. The Series B funding was allocated to support ongoing clinical trials for ANPD001, scale manufacturing capabilities to meet clinical and future commercial demand, and advance the company's pipeline of iPSC-derived therapies for additional neurological indications. Aspen was founded in 2018 with $6.5 million in seed funding, followed by a $70 million Series A in early 2020. The company later closed a Series C round of $115 million in November 2025, bringing total capital raised to over $340 million including an $8 million grant from the California Institute for Regenerative Medicine. |
| Apr 2020 | Series A | OrbiMed (lead); S32; Domain Associates; Frazier Healthcare Partners; Sam Altman; ARCH Venture Partners | $70M | Aspen Neuroscience is a clinical-stage biotechnology company pioneering autologous regenerative therapies, with a focus on developing personalized cell therapies for neurological diseases including Parkinson's disease. The company's lead program, ANPD001, is an investigational autologous dopaminergic neuronal precursor cell therapy that reprograms a patient's own skin cells into pluripotent stem cells, which are then differentiated into neurons for transplantation back into the patient's brain. In April 2020, Aspen closed a Series A funding round of $70 million led by OrbiMed with participation from ARCH Venture Partners, Frazier Healthcare Partners, Domain Associates, Section 32, and entrepreneur Sam Altman. The Series A proceeds were designated to support Phase 1 clinical development of ANPD001 and position the second program ANPD002 for IND filing, while also supporting continued R&D pipeline development for autologous gene-corrected dopamine neurons and programs exploring treatment of neuroinflammation-marked diseases. As a clinical-stage biotech in early development phases at the time of the Series A round, Aspen had not generated commercial revenue or reported EBITDA metrics, which is typical for pre-clinical and early-stage therapeutic development companies. The company subsequently raised a Series B of $147.5 million in May 2022 and a Series C of $115 million in November 2025, bringing total capital raised to over $340 million including grants, positioning the company toward late-stage development and potential commercialization pathways. |
| Dec 2019 | Seed | Domain Associates (lead); Alexandria Venture Investments; S32; OrbiMed; Axon Ventures; ARCH Venture Partners | $7M | Aspen Neuroscience was founded in 2018 with $6.5 million in seed funding led by Domain Associates and Axon Ventures, including Alexandria Venture Investments, ARCH Venture Partners, OrbiMed, and Section 32. The company develops autologous regenerative therapies using a patient-derived iPSC platform for neurodegenerative disorders like Parkinson's disease, with lead candidate ANPD001. Subsequent rounds include a $70 million Series A in early 2020 led by OrbiMed, a $147 million Series B in early 2022 co-led by Google Ventures, LYFE Capital, and Revelation Partners, and a $115 million Series C in November 2025 co-led by OrbiMed, ARCH Venture Partners, Frazier Life Sciences, and Revelation Partners, bringing total capital raised to over $340 million plus an $8 million CIRM grant. |
