Epicrispr and Infinimmune raise $165 million to advance drug pipelines

Epicrispr Biotechnologies and Infinimmune have closed separate fundraising rounds to support the development of their respective treatments for neuromuscular and inflammatory conditions, according to an Aug. 11 announcement.

Epicrispr secured $90 million in a series C round, which will be used to further its work on programmable epigenetic therapies targeting neuromuscular diseases. The company's lead asset, EPI-321, is undergoing first-in-human testing for facioscapulohumeral muscular dystrophy (FSHD). Enrollment for this study has been completed, with data expected later this year. EPI-321 is designed as a one-time therapy that uses an adeno-associated virus vector to target muscle tissue and suppress expression of the DUX4 gene, which drives FSHD. Early-stage trial findings released in June showed an average lean muscle volume increase of about 370 mL in three patients who received EPI-321. Epicrispr has also reported strength and functional improvements among these patients after treatment.

The series C round was co-led by Janus Henderson Investors and Octagon Capital, with participation from Sanofi Ventures, Angelini Ventures, and Cormorant Asset Management.

Infinimmune raised $75 million in a series A round that will support clinical development of two atopic dermatitis drugs. The company plans to begin first-in-human studies for these molecules next year. Its assets include anti-IL-22 therapy IFX-101 and IL-13–targeting IFX-201—both monoclonal antibodies discovered using the company’s Anthrobody technology that screens millions of memory B cells for potential therapeutic antibodies. Merck entered into a partnership with Infinimmune in March worth up to $838 million focused on multiple undisclosed targets using this approach.

With these fundraising rounds, Epicrispr and Infinimmune join other biopharma companies benefiting from what experts described as a selective recovery of venture capital investment in July. Robert Stanislaro, senior managing director at FTI Consulting, said, “This trend reflects a bigger picture. Capital hasn’t dried up, but it has become far more discerning about where it goes.”
