Program details

Where each program stands.

ATR-258 · Skeletal Muscle Health, Sarcopenia

Phase I
Addressable population · Aging population worldwide

Insulin-independent glucose uptake via GRK2→mTORC2→GLUT4. Exercise-mimetic effects on muscle preservation and metabolic function. Next: ATTRACTIVE 3 proof-of-concept.

ATR-258 · Obesity / GLP-1 Add-on

Phase I
Addressable population · 1B+ adults worldwide

Muscle-sparing complement to GLP-1 receptor agonists. Preclinical combo data shows prevention of liraglutide-induced muscle loss. Next: ATTRACTIVE 4.

ATR-339 · Obesity

Preclinical

Advanced muscle-sparing GLP-1 complement. Preclinical combo data shows accelerated healthy weight loss and prevention of liraglutide-induced muscle degradation. Next: Toxicology studies.

Next-Gen · Muscle Wasting, DMD, FSHD

Discovery
Addressable population · Aging population

Extended compound library targeting sarcopenia, cachexia, and FSHD. 1,000+ rationally designed compounds. Lead selection underway.
