SHANGHAI and PRINCETON, N.J., April 29, 2022 (GLOBE NEWSWIRE) — LianBio’s (Nasdaq: LIAN) partner, Bristol Myers Squibb, announced yesterday that the U.S. Food and Drug Administration (FDA) approved Camzyos™ (mavacamten, 2.5 mg, 5 mg, 10 mg and 15 mg capsules) for the treatment of adults with symptomatic New York Heart Association (NYHA) class II-III obstructive hypertrophic cardiomyopathy (obstructive HCM) to improve functional capacity and symptoms. Camzyos is the first and only FDA-approved allosteric and reversible inhibitor selective for cardiac myosin that targets the underlying pathophysiology of obstructive HCM.
LianBio licensed rights from MyoKardia, now a wholly owned subsidiary of Bristol Myers Squibb, in August 2020 for the development and commercialization of Camzyos in Mainland China, Hong Kong, Macau, Taiwan, Thailand and Singapore. LianBio is currently conducting EXPLORER-CN, a Phase 3 multicenter, double-blind, randomized, placebo-controlled registrational study designed to evaluate the safety and efficacy of mavacamten in Chinese patients with symptomatic obstructive HCM. Camzyos was granted Breakthrough Therapy Designation in China for the treatment of patients with obstructive HCM.
“We congratulate Bristol Myers Squibb on receiving U.S. FDA approval for Camzyos in patients with symptomatic NYHA class II-III obstructive HCM,” said Yizhe Wang, Ph.D., chief executive officer of LianBio. “Obstructive HCM is a debilitating heart disease with significant unmet medical need in China. We estimate there are approximately 1.1 million to 2.8 million patients with HCM in China, and approximately two-thirds of those patients have symptomatic obstructive HCM. We are excited to continue our strategic collaboration and further development of Camzyos in China and other Asian markets to help bring this promising treatment to patients in need.”
About Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is a chronic, progressive disease in which excessive contraction of the heart muscle and reduced ability of the left ventricle to fill can lead to the development of debilitating symptoms and cardiac dysfunction. HCM is estimated to affect one in every 500 people globally.
The most frequent cause of HCM is mutations in the heart muscle proteins of the sarcomere. In both obstructive and non-obstructive HCM patients, exertion can result in fatigue or shortness of breath, interfering with a patient’s ability to participate in activities of daily living. HCM has also been associated with increased risks of atrial fibrillation, stroke, heart failure and sudden cardiac death.
Camzyos™ (mavacamten) is the first and only cardiac myosin inhibitor approved by the FDA indicated for the treatment of adults with symptomatic New York Heart Association (NYHA) class II-III obstructive HCM to improve functional capacity and symptoms. Camzyos is an allosteric and reversible inhibitor selective for cardiac myosin. Camzyos modulates the number of myosin heads that can enter “on actin” (power generating) states, thus reducing the probability of force producing (systolic) and residual (diastolic) cross-bridge formation. Excess myosin actin cross bridge formation and dysregulation of the super relaxed state are mechanistic hallmarks of HCM. Camzyos shifts the overall myosin population towards an energy sparing, recruitable, super relaxed state. In HCM patients, myosin inhibition with Camzyos reduces dynamic left ventricular outflow tract (LVOT) obstruction and improves cardiac filling pressures.
