MyoKardia Reports Second Quarter 2019 Financial Results


Announces Last Patient to be Enrolled in EXPLORER-HCM Phase 3 during the Week of

August 12th, Topline Data Accelerated to 2nd Quarter 2020


Topline Phase 2 Clinical Data from MAVERICK-HCM and MYK-491 on Track for
Fourth Quarter 2019


Company to Host Conference Call and Webcast Today at 4:30 p.m. ET (1:30 p.m. PT)


SOUTH SAN FRANCISCO, Calif., Aug. 07, 2019 -- MyoKardia, Inc. (Nasdaq: MYOK) today reported financial results for the second quarter ended June 30, 2019.


“We are now less than a year away from potentially game-changing pivotal data from our EXPLORER-HCM clinical trial of mavacamten in obstructive HCM, with activities in full swing for NDA preparation and potential commercial introduction of MyoKardia’s first product,” said Tassos Gianakakos, MyoKardia’s Chief Executive Officer.  “The remainder of this year will see us share multiple meaningful clinical results including topline data from our Phase 2 MAVERICK-HCM study in patients with non-obstructive HCM and from our Phase 2 study of MYK-491 for patients with stable heart failure.  We will also be advancing our third clinical-stage compound, MYK-224, into a Phase 1 clinical trial.  Taken together, these events highlight the meaningful progress we continue to make in the development of much-needed new treatments for serious cardiovascular diseases.”  


Recent Clinical Program Highlights


Mavacamten for Hypertrophic Cardiomyopathy (HCM)


Enrollment in EXPLORER-HCM Phase 3 Clinical Study Nearing Completion: Patient enrollment for the Phase 3 EXPLORER-HCM registrational clinical study to assess the effect of mavacamten in treating patients with symptomatic, obstructive HCM is scheduled to end next week.  Clinical site engagement was high, allowing for enrollment above the target of 220 patients to be completed ahead of expectations. MyoKardia now anticipates reporting topline data from the EXPLORER-HCM trial in the second quarter of 2020, ahead of the previous guidance of the second half of 2020.



Completed Enrollment in the MAVERICK-HCM Phase 2 Clinical Trial: In May, MyoKardia announced the completion of enrollment in the Phase 2 MAVERICK-HCM study of mavacamten for the treatment of non-obstructive HCM.  The randomized, double-blind, placebo-controlled MAVERICK-HCM Phase 2 clinical trial is designed to assess the safety and tolerability of a 16-week treatment course of mavacamten in patients with non-obstructive HCM.  MyoKardia plans to report topline data from the MAVERICK-HCM study in the fourth quarter of 2019.



Published Data in Nature Digital Medicine Showing Potential of Wrist-Worn Biosensor to Screen for Hypertrophic Cardiomyopathy: Results from an exploratory study demonstrated the potential to screen for obstructive HCM using a photoplethysmography (PPG) digital health device, similar to the optical sensors that monitor heart rate on commercially available fitness trackers.  Continuous monitoring with a wrist-worn biosensor revealed differences in arterial pulse wave patterns between obstructive HCM patients and those of individuals without obstructive HCM. MyoKardia’s proprietary machine learning algorithm identified individuals with obstructive HCM with a sensitivity of 0.95 and a specificity of 0.98. The digital health substudy was conducted by MyoKardia as part of the company’s Phase 2 PIONEER-HCM trial of mavacamten.



Driven by the Heart




333 Allerton Avenue, South San Francisco, CA 94080 / +1 650 741-0900/




MYK-491 for Dilated Cardiomyopathy (DCM)


Presented results from Phase 1a Clinical Trial of MYK-491 at the European Society of Cardiology Heart Failure Congress: First-in-human data from the Phase 1a clinical trial of MYK-491 in healthy volunteers showed the drug to be well tolerated. MYK-491 increased cardiac contractility by 5-20 percent across multiple echocardiographic parameters at higher drug concentrations, with minimal impact on diastolic function.  MYK-491 is currently being studied in a Phase 2a multiple-ascending dose clinical trial for the treatment of patients with systolic heart failure, in which the heart is unable to contract sufficiently to meet the demands of the body.  Data from this study are anticipated in the fourth quarter of 2019.


Recent Corporate Highlights



Re-acquired U.S. Royalty Rights to HCM Programs from Sanofi: MyoKardia completed the re-acquisition of U.S. royalty rights to mavacamten and MYK-224 from Sanofi. As consideration for the buyback of the U.S. royalty rights to these programs, MyoKardia paid Sanofi $50 million upfront, with an additional $30 million payable by June 30, 2020.  Under the terms of the former license and collaboration agreement with Sanofi, Sanofi was eligible for tiered royalties, ranging from 5 percent to 10 percent, on U.S. sales of mavacamten and MYK-224 in HCM or any additional indications.


Second Quarter 2019 Financial Results



Cash Position: Cash, cash equivalents and investments (short-term and long-term) as of June 30, 2019 were $602.4 million, compared to $394.8 million as of December 31, 2018.  The increase in the company’s cash position is primarily attributable to net proceeds of approximately $271.2 million from MyoKardia’s follow-on offering of common stock, which priced in March 2019.



Revenue: In the second quarter of 2019, MyoKardia recorded no revenue from collaborations, compared with $6.6 million during the same period in 2018.  As of December 31, 2018, MyoKardia had fulfilled all of its performance obligations to Sanofi, and no further revenue will be recorded from the Sanofi collaboration agreement.  



R&D Expenses: Research and development expenses were $27.7 million in the second quarter 2019, up from $17.2 million (net of Sanofi credits of $8.6 and $4.3 million) for the same period in 2018. For the six months ended June 30, 2019, R&D expenses were $53.9 million compared to $33.8 million in the first half of 2018, net of Sanofi credits of $18.5 million and $7.1 million, respectively.  The increase in R&D expenses was primarily driven by increases in clinical expenses related to the mavacamten and MYK-491 clinical trials, an increase in personnel-related costs and increases in contract research, chemistry and biology expenses related to discovery and pre-clinical programs.  



G&A Expenses: General and administrative expenses were $13.9 million for the three months ended June 30, 2019, compared to $8.9 million for the same period in 2018.  For the first half of 2019, G&A expenses totaled $27.4 million compared to $16.2 million in the first half of 2018.  The increase in G&A expense was primarily driven by an increase in personnel expenses and stock compensation due to higher headcount, as well as an increase in professional service and consulting fees.



Net Loss: Net loss was $38.2 million ($0.83 loss per share) for the second quarter of 2019, compared to a net loss of $18.4 million ($0.49 loss per share) for the second quarter of 2018.  For the six months ended June 30, 2019, net loss was $75.6 million ($1.75 loss per share) compared to $36.2 million ($0.99 loss per share) during the same period of 2018.


Financial Guidance

Based on its current operating plans, MyoKardia anticipates that current cash, cash equivalents and investments are sufficient to fund operations into the second half of 2021.

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 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 underlying 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 people with serious cardiovascular disease through bold and innovative science.
