What is felycin®-CA1?
felycin®-CA1 is the first ever conditionally approved drug for cats with heart disease. felycin®-CA1 is indicated for the management of ventricular hypertrophy in cats with subclinical hypertrophic cardiomyopathy (HCM).
felycin®-CA1’s species-specific delayed-release formulation targets the subclinical phase of the disease, prior to the onset of heart failure, and has been shown to reduce thickening (hypertrophy) of the ventricular wall. The medication is available by prescription only, and is administered once weekly. felycin-CA1 is set to fundamentally change the feline HCM treatment landscape.
felycin®-CA1 is anticipated to be available in the summer of 2025. To receive updates regarding its market release, safety information, educational materials, and ordering details upon launch, please complete the form below to register for updates.

“Delayed-release rapamycin halts progression of left ventricular hypertrophy in subclinical feline hypertrophic cardiomyopathy: results of the RAPACAT trial”1
Study Results:
When followed up over 6 months, untreated cats with subclinical HCM experience marked thickening (hypertrophy) of their left ventricleCats with higher levels of NTproBNP (a blood marker for cardiac disease) have more rapid progression of hypertrophy
Intermittent inhibition of mTOR prevented progression of hypertrophy
The HALT Study
The HALT HCM Study is a blinded, randomized, placebo-controlled trial of felycin®-CA1 in the management of ventricular hypertrophy associated with feline subclinical hypertrophic cardiomyopathy (HCM). The objective of the study is to provide substantial evidence of the effectiveness and safety of 12 months’ dosing of once-weekly felycin®-CA1 in feline subclinical HCM. The study is being conducted around 25 clinical sites across the United States that are experienced in treating cats with HCM. It will aim to enroll 300 cats.
