Putting Muscle Behind Our Mission

Putting Muscle Behind Our Mission

We are committed to developing potential medicines that may improve the healthspan of people living with cardiovascular and neuromuscular diseases of impaired muscle function.

Some of these life-altering diseases include heart failure, hypertrophic cardiomyopathy (HCM disease), and amyotrophic lateral sclerosis (ALS).

By impacting the mechanics of muscle with investigational medicines that may improve muscle strength, power, or performance, we aspire to develop new medicines that may improve patient outcomes for people living with these debilitating diseases.

The Science of Muscle

At Cytokinetics our research is focused to modulating proteins in the sarcomere, the fundamental unit of muscle contraction found within muscle cells. These crucial proteins are the keys to unlock the potential treatment of diseases that are caused by impaired muscle function.


Heart failure is a progressive condition in which the heart becomes enlarged, thickened or rigid, causing it to become too weak or stiff to fill and pump blood throughout the body.

About HF

HCM is a progressive condition that causes the heart to thicken. The thickened walls may become stiff, reducing the amount of blood taken in and pumped out of the body with each heartbeat.

About HCM Disease


Neuromuscular diseases impact the nerve cells that send messages from the brain and spinal cord to muscles throughout the body, often resulting in muscle weakness or loss.
