What Armatus Bio does

Armatus Bio is a late-preclinical stage biotechnology company developing vectorized RNA interference (RNAi) therapeutics for rare neuromuscular diseases with no approved disease-modifying treatments. Founded in 2021 and headquartered in Columbus, Ohio, the company operates with a lean team of 1-10 employees and is backed by venture philanthropy organizations including the Charcot-Marie-Tooth Association (CMTA) and SOLVE FSHD. Its lead programs are TVR110, an AAV9-delivered engineered microRNA designed to silence PMP22 overexpression in Charcot-Marie-Tooth disease type 1A (CMT1A) via one-time intrathecal administration, and ARM-201, an AAV-delivered microRNA using the AAV-SLB101 myotropic capsid (licensed from Solid Biosciences) to silence toxic DUX4 expression in facioscapulohumeral muscular dystrophy (FSHD) via one-time systemic delivery. Both candidates have received FDA Orphan Drug Designation and Rare Pediatric Disease Designation, and the company has completed successful pre-IND meetings with the FDA for each program.

The company's underlying platform is the SPRINT Discovery Engine, which enables rapid evaluation of engineered miRNA payloads with emphasis on translational fidelity, complemented by a Scalable Potency Assay Platform published in Molecular Therapy Advances for product release, stability, and manufacturing comparability. Preclinical performance data includes 38% PMP22 mRNA and protein knockdown in vivo, 25x higher binding affinity for PMP22 versus any other genomic site, and absence of dorsal root ganglia inflammation. Scientific work is conducted in collaboration with the Nationwide Children's Hospital Center for Gene Therapy (anchored by Chief Scientific Advisor Scott Q. Harper, PhD) and the Cyprus Institute of Neurology and Genetics. The addressable patient population across both lead indications exceeds 225,000 people in the US and EU.

Armatus Bio is pre-revenue with no approved products and no current pricing model. Its go-to-market strategy targets rare disease patient populations through orphan and pediatric regulatory pathways, with planned future distribution through specialty pharmacy networks and certified treatment centers typical of one-time gene therapies. The company has indicated IND submission for TVR110 is planned in 2025, with ARM-201 in IND-enabling activities. Revenue mechanics will derive from product sales as a biopharmaceutical upon regulatory approval, likely under premium orphan-disease pricing. Current revenue is zero; capital is sourced exclusively from venture philanthropy funding rounds, with approximately $3 million disclosed to date.

Revenue model

1. Gene Therapy Development and Commercialization: As a preclinical-stage biotech company, Armatus Bio is in the research and development phase with no current revenue. The company is developing vectorized RNAi therapeutics for rare neuromuscular diseases and plans to commercialize its pipeline candidates (TVR110 for CMT1A and ARM-201 for FSHD) upon regulatory approval. Revenue will be derived from product sales as a biopharmaceutical, likely with premium pricing typical of orphan/rare disease therapies with disease-modifying potential.

Core offering

Armatus Bio is a late-preclinical stage biotech company developing vectorized RNAi (RNA interference) therapeutics using AAV-delivered engineered microRNAs for rare neuromuscular diseases. Its lead candidates include TVR110, an AAV9-delivered engineered microRNA for Charcot-Marie-Tooth disease type 1A (CMT1A) administered via one-time intrathecal delivery to reduce PMP22 overexpression, and ARM-201, an AAV-SLB101-delivered microRNA for facioscapulohumeral muscular dystrophy (FSHD) designed to silence toxic DUX4 expression.

Product overview

Armatus Bio is a late-preclinical stage biotech company developing vectorized RNAi (RNA interference) therapeutics for rare neuromuscular diseases. The company operates a platform-based approach with its SPRINT Discovery Engine for miRNA payload evaluation. Two lead product candidates are in late preclinical development: TVR110 (for Charcot-Marie-Tooth disease type 1A) and ARM-201 (for facioscapulohumeral muscular dystrophy). Both use AAV-delivered engineered microRNAs to silence disease-driving genes without altering the underlying genetic makeup.
