Advisory Committee Meeting to Review NDA for Omecamtiv Mecarbil Scheduled for December 13, 2022; PDUFA Target Action Date Set for February 28, 2023

Company Revises 2022 Financial Guidance; Reduces Projected Spending for 2022

SOUTH SAN FRANCISCO, Calif., Aug. 04, 2022 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (NASDAQ:CYTK) reported financial results for the second quarter of 2022. Net loss for the second quarter was $19.8 million, or $0.23 per share, compared to net loss for the second quarter of 2021 of $61.6 million, or $0.86 per share. Cash, cash equivalents and investments totaled $596.7 million at June 30, 2022.

In July, Cytokinetics raised $540 million netting approximately $383 million in proceeds through the offering of convertible senior notes, after deducting the purchasers' discounts and commissions and Cytokinetics' estimated offering expenses, as well as deducting $140.3 million to repurchase previously outstanding convertible senior notes. Cytokinetics expects to end 2022 with more than $800 million in cash.

"During the second quarter we made progress across regulatory, clinical and financial objectives. We engaged extensively with FDA in planning for its review of our NDA for omecamtiv mecarbil and advanced the enrollment and conduct of SEQUOIA-HCM and COURAGE-ALS while also planning for a second Phase 3 trial of aficamten," said Robert I Blum, Cytokinetics' President and Chief Executive Officer. "We also bolstered our balance sheet by executing on a fundraising of over $500 million while reducing our planned nearer-term spending in 2022. We believe that we are in a strong position to bring our potential therapies to patients while also executing well on late-stage clinical development programs."

Q2 and Recent Highlights

Cardiac Muscle Programs

omecamtiv mecarbil (cardiac myosin activator)

Participated in a mid-cycle review meeting with the U.S. Food and Drug Administration (FDA) related to our New Drug Application (NDA) for omecamtiv mecarbil. Engaged extensively with FDA in other interactions related to its review of our NDA.
Received notice that the FDA plans to convene an Advisory Committee meeting to review the NDA for omecamtiv mecarbil, and that the meeting is currently scheduled for December 13, 2022.
Received notice that the FDA extended the Prescription Drug User Fee Act (PDUFA) date for omecamtiv mecarbil to February 28, 2023 due to additional pharmacokinetic analyses of omecamtiv mecarbil provided to the FDA upon request and that are deemed to constitute a major amendment to the NDA.
Hired and deployed Managed Healthcare Medical Scientists and initiated medical support of our global value, access and distribution services. Continued building headquarters-based commercial infrastructure and engaging in launch readiness activities, including pre-approval information exchange discussions with key payers. Conducted Business Process inventory for enterprise resource planning implementation and strategic sourcing activities to mitigate supply chain risks.
Presented additional data from GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) at Heart Failure 2022, an International Congress of the European Society of Cardiology, including:
- An analysis showing that in patients with low blood pressure, there was a greater treatment effect from omecamtiv mecarbil on the primary composite endpoint of cardiovascular death or first heart failure event than in patients without low blood pressure such that there was an absolute risk reduction of 9.8 events per 100 patient-years (hazard ratio, 0.81; 95% confidence interval [CI] 0.70, 0.94; interaction p=0.051).
- An analysis showing that the treatment effect of omecamtiv mecarbil on the primary composite endpoint was consistent across patients with no tricuspid regurgitation (TR), mild TR and moderate/severe TR such that baseline TR did not modify the treatment effect (interaction p=0.91).

Presented additional data from GALACTIC-HF at the American College of Cardiology 71^st Annual Scientific Session (ACC.22) including:
- An analysis showing that treatment with omecamtiv mecarbil in a subgroup of patients in GALACTIC-HF led to a reduction in resource intensity, with an estimated cost offset of $3,085, or a 19% reduction in costs per patient. The majority of cost reductions were due to heart failure hospitalizations avoided by patients treated with omecamtiv mecarbil.
- An analysis showing that the effect of treatment with omecamtiv mecarbil was associated with similar risk reduction in the primary composite endpoint in both hospitalized patients and in outpatients, indicating that initiation of omecamtiv mecarbil was safe and well tolerated in both hospitalized patients and outpatients.

Announced results of METEORIC-HF (Multicenter Exercise Tolerance Evaluation of Omecamtiv Mecarbil Related to Increased Contractility in Heart Failure), a Phase 3 clinical trial of omecamtiv mecarbil in patients with HFrEF that evaluated the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity as determined by cardiopulmonary exercise testing (CPET). After 20 weeks of treatment, there was no change in peak oxygen uptake (pVO₂) in patients treated with omecamtiv mecarbil versus placebo. Adverse events, including major cardiac events, were similar between the treatment arms, and the safety profile of omecamtiv mecarbil was consistent with prior clinical trials, including GALACTIC-HF.
Published a manuscript entitled "Effects of Omecamtiv Mecarbil in Heart Failure with Reduced Ejection Fraction According to Blood Pressure: The GALACTIC-HF Trial" in the European Heart Journal.
Published a manuscript entitled "The Effect of Omecamtiv Mecarbil on Exercise Capacity in Chronic Heart Failure with Reduced Ejection Fraction: The METEORIC-HF Randomized Trial" in the Journal of the American Medical Association.

aficamten (cardiac myosin inhibitor)

Presented the first long-term data from REDWOOD-HCM OLE (Randomized Evaluation of Dosing With CK-274 in Obstructive Outflow Disease in HCM Open Label Extension) at Heart Failure 2022 from 38 patients treated for up to 24 weeks showing that treatment with aficamten was associated with substantial reductions in the average resting left ventricular outflow tract gradient (LVOT-G) and Valsalva LVOT-G. The reductions started to occur within two weeks of treatment, were sustained through 24 weeks of treatment, and were achieved with only modest decreases in the average LVEF. Improvements were also observed in New York Heart Association (NYHA) Functional Class and cardiac biomarkers including NTpro-BNP and cardiac troponin. Treatment with aficamten was well-tolerated with one temporary discontinuation due to LVEF <50% and one temporary down-titration, neither related to drug. Both patients remain on treatment with aficamten.
Presented additional data from REDWOOD-HCM at the American Society of Echocardiography (ASE) 33rd Annual Scientific Sessions showing that measures of cardiac structure, diastolic and mitral valve function improved in patients treated with aficamten after 10 weeks, including a significant reduction in left atrial volume index (p<0.01) and a trend towards a reduction in left ventricular hypertrophy (left ventricular mass index; p=0.06). Treatment with aficamten also resulted in improved ventricular relaxation and filling, as indicated by a reduction in lateral E/e' (p<0.01) and an increase in lateral e' (p<0.05).
Announced positive data from Cohort 3 of REDWOOD-HCM, which enrolled patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM) and a resting left LVOT-G ≥50, or resting LVOT-G ≥30 mmHg and post-Valsalva LVOT-G ≥50 mmHg, whose background therapy included disopyramide and in the majority a beta-adrenergic blocker. Results showed that substantial reductions in the average resting LVOT-G as well as the post-Valsalva LVOT-G (defined as resting gradient <30 mmHg and post-Valsalva gradient <50 mmHg) were achieved. The safety and tolerability of aficamten were consistent with prior experience in REDWOOD-HCM with no treatment interruptions and no serious adverse events attributed to treatment reported by the investigators.
Began developing the go-to-market strategy for aficamten to support its potential future commercialization.
Published a manuscript entitled "Characteristics of Patients with Obstructive Hypertrophic Cardiomyopathy in Real-World Community-Based Cardiovascular Practices" in The American Journal of Cardiology.

Financials

Revenues for the three and six months ended June 30, 2022 were $89.0 million and $90.1 million, respectively, compared to $2.8 million and $9.4 million for the corresponding period in 2021. The increase in revenues was primarily due to the recognition of $87.0 million of deferred revenue for royalties on the net sales of products containing mavacamten as a result of the extinguishment of royalty obligations.

Research and development expenses for the three and six months ended June 30, 2022 increased to $57.1 million and $103.1 million, respectively, compared to $36.4 million and $68.0 million for the same period in 2021. The changes were primarily due to increases in spending for clinical development activities for COURAGE-ALS, for our cardiac muscle inhibitor programs, and early research programs.

General and administrative expenses for the three and six months ended June 30, 2022 increased to $42.7 million and $75.8 million, respectively, from $21.2 million and $36.8 for the same period in 2021 due primarily to higher outside services spending in anticipation of the potential commercial launch of omecamtiv mecarbil, and an increase in personnel related costs including stock-based compensation.

Revised 2022 Financial Guidance

The company today revised its financial guidance related to a reduction in expected operating expenses as a result of the three-month extension of the PDUFA date for omecamtiv mecarbil to February 28, 2023, which shifted certain hiring and activities previously planned to occur in 2022 to 2023. The company anticipates operating expenses for 2022 will be in the range of $375 to $385 million, and net cash utilization will be approximately $360 to $365 million. The company expects to end 2022 with more than $800 million, representing between two and three years of forward cash.
