The brief
- Linnaeus is a Penn spinout founded in 2016. LNS8801 activates estrogen receptor to preserve physical and cognitive aging.
- 100+ cancer patients treated in phase 1/2 with good safety. ARPA-H awarded $22M for PROSPR healthspan trial.
Technical approach
Activates estrogen receptor GPER
Selectively activates G protein-coupled estrogen receptor (GPER), regulating aging-related changes in muscle, bone, cardiovascular and cognitive function.
Estrogen benefits without sex hormones
Captures estrogen's protective effects on aging tissues without activating nuclear estrogen receptors, avoiding feminization and cancer risk.
Once daily oral pill
Small molecule that crosses the blood-brain barrier, allowing once-daily dosing for peripheral and cognitive aging.
Multiple aging systems affected
GPER activation influences cardiometabolic, physical capacity, neuroinflammation and senescence.
