MyoKardia, Inc. (Nasdaq: MYOK), a clinical-stage biopharmaceutical company pioneering precision medicine for the treatment of cardiovascular diseases, today announced it has regained worldwide rights to all programs covered under its license and collaboration agreement with Sanofi. The collaboration will not be extended beyond the initial research term, which ended on December 31, 2018, and will conclude in its entirety effective April 1, 2019. As a result, MyoKardia now has global rights to all programs in its portfolio, including lead clinical-stage candidates, mavacamten and MYK-491.

“We are grateful for Sanofi’s support over the past four years in what was a highly productive relationship. Since entering into the collaboration, MyoKardia has become a leading research and development organization with a robust pipeline of targeted cardiovascular therapeutics,” said Tassos Gianakakos, MyoKardia’s chief executive officer. “Regaining worldwide rights enables us to capture the full value of the data being generated in the next 12-24 months as we prepare for the potential registration of mavacamten in obstructive hypertrophic cardiomyopathy and obtain proof-of-concept for MYK-491 in patients with dilated cardiomyopathy. Importantly, consolidated control over our entire portfolio allows us to make decisions about how we advance each of our therapeutic candidates in alignment with our precision medicine approach.”

MyoKardia and Sanofi initiated their collaboration in 2014 to advance up to three programs through discovery and into clinical development for the treatment of hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). Over the course of the collaboration, MyoKardia received approximately $230 million in funding from Sanofi and has advanced mavacamten from preclinical development into a late-stage pivotal study for the treatment of HCM, and MYK-491 from discovery to a Phase 2 proof-of-concept study in patients with DCM. During the period leading up to the end of the research term, it was important for MyoKardia to maintain 100 percent of the U.S. commercial rights for mavacamten in HCM as well as additional rights in expanded indications. Sanofi subsequently provided MyoKardia with notification of its decision to conclude the collaboration in conjunction with the end of the research term.

MyoKardia is positioned to achieve several significant clinical milestones over the next 12 to 24 months and reaffirmed timing for anticipated data read-outs:

> 6-month and 12-month data for mavacamten in obstructive HCM (oHCM) from the ongoing PIONEER open-label extension study

> Data from the Phase 2 MAVERICK study in non-obstructive HCM in the second half of this year

> Topline data from the Phase 3 EXPLORER-HCM clinical trial of mavacamten in obstructive HCM (oHCM) in the second half of 2020

> Phase 2a proof-of-concept data for MYK-491 in DCM before the end of the year

The company anticipates that current cash, cash equivalents and investments are sufficient to fund operations past the read-out of EXPLORER-HCM data in the second half of 2020. This reflects an anticipated increase in R&D expenses due to the termination of the Sanofi collaboration agreement. As of September 30, 2018, MyoKardia had cash, cash equivalents and investments totaling $412 million. MyoKardia will report fourth quarter and year-end 2018 financial results in late February of 2019.

About MyoKardia

MyoKardia is a clinical-stage biopharmaceutical company pioneering a precision medicine approach to discover, develop and commercialize targeted therapies for the treatment of serious and rare cardiovascular diseases. MyoKardia’s initial focus is on the development of small molecule therapeutics aimed at the cardiac muscle proteins that modulate cardiac muscle contraction and underlie diseases of systolic and diastolic dysfunction. Based on an in-depth understanding of disease biology, MyoKardia applies a precision medicine approach to develop its therapeutic candidates for patient populations with shared characteristics, such as causal genetic mutations or disease subtypes. MyoKardia’s most advanced product candidate is mavacamten (formerly MYK-461), a novel, oral, allosteric modulator of cardiac myosin intended to reduce hypercontractility. Mavacamten has advanced into a pivotal Phase 3 clinical trial, known as EXPLORER-HCM in patients with symptomatic, obstructive hypertrophic cardiomyopathy (HCM). MyoKardia is also developing mavacamten in a second indication, non-obstructive HCM, in the Phase 2 MAVERICK-HCM clinical trial. MYK-491, MyoKardia’s second product candidate, is designed to increase cardiac output among patients with systolic heart dysfunction by increasing the overall extent of the heart’s cardiac contractility. MyoKardia is currently evaluating MYK-491 in a Phase 1b/2a study in stable heart failure patients.

MyoKardia’s mission is to change the world for patients with serious cardiovascular disease through bold and innovative science.
