Cytokinetics: Clinical Investigators’ Opinions On ATOMIC-AHF Trial Results

Cytokinetics, Inc. (CYTK): Cytokinetics: Clinical Investigators’ Opinions On
Seeking Alpha
Pending the results of the ongoing COSMIC-HF trial in 1H, 2014, I believe that the ATOMIC-AHF results support moving omecamtiv mecarbil into Phase III. With success in the Phase III, omecamtiv mecarbil would likely be a several billion drug. I regard http://seekingalpha.com/article/1672892-cytokinetics-clinical-investigators-opinions-on-atomic-ahf-trial-results?source=google_news

 

Omecamtiv mecarbil (INN), previously codenamed CK-1827452, is a cardiac specific myosin activator. It is clinically tested for its role in the treatment of left ventricular systolic heart failure.[1] Systolic heart failure is characterised as a decreased cardiac output (<40% ejection fraction), due to decreased stroke volume, resulting in the inability to meet the metabolic demands of the body.[2] The loss of contraction is caused by a reduced number of effective actin-myosin cross bridges in the left ventricular myocytes. One possible underlying mechanism is altered signal transduction that interferes with excitation-contraction coupling.[3] A decreased cardiac output causes peripheral hypotension and activation of the sympathetic nervous system.[2] This in turn stimulates the cardiac myocytes excessively, eventually leading to left ventricular hypertrophy, characteristic of chronic heart failure. Some symptoms of systolic heart failure are fatigue, peripheral oedema, dyspnoea, exercise intolerance and breathlessness.[2] Current inotropic drug therapies such as dobutamine, are palliative and not a cure. They also cause many adverse effects including arrhythmias related to increased myocardical oxygen consumption, desensitization of adrenergic receptors and altering intracellular calcium levels.[4] Thus systolic heart failure is considered malignant, however the novel mechanism of Omecamtiv Mecarbil is a hopeful long-term resolution.

Mechanism of action

Cardiac myocytes contract through a cross-bridge cycle between the myofilaments, actin and myosin. Chemical energy in the form of ATP is converted into mechanical energy which allows myosin to strongly bind to actin and produce a power stroke resulting in sarcomere shortening/contraction.[3] Omecamtiv Mecarbil specifically targets and activates myocardial ATPase and improves energy utilization. This enhances effective myosin cross-bridge formation and duration, while the velocity of contraction remains the same.[5] It also increases the rate of phosphate release from myosin, thereby accelerating the rate-determining step of the cross-bridge cycle, which is the transition of the actin-myosin complex from the weakly bound to the strongly bound state.[1] The overall result of Omecamtiv Mecarbil is an increase in left ventricular systolic ejection time, sarcomere shortening and stroke volume, while the systolic pressure remains the same.[5] This causes a decrease in heart rate while myocardial oxygen consumption is unaffected. The increased cardiac output is independent of intracellular calcium and cAMP levels.[4][6] Thus Omecamtiv Mecarbil improves systolic function by increasing the systolic ejection duration/stroke volume, without consuming more ATP energy, oxygen or altering intracellular calcium levels causing an overall improvement in cardiac efficiency.[5]

Clinical trials

Experimental studies on rats and dogs, proved the efficacy and mechanism of action of Omecamtiv Mecarbil.[4] Current clinical studies on humans have shown there is a direct linear relationship between dose and systolic ejection time.[1][7][8] The dose-dependent effects persisted throughout the entire trial, suggesting that desensitization does not occur. The maximum tolerated dose was observed to be an infusion of 0.5 mg/kg/h. Adverse effects, such as ischemia, were only seen at doses beyond this level, due to extreme lengthening of systolic ejection time.[1] Thus due to the unique cardiac myosin activation mechanism, Omecamtiv Mecarbil could safely improve cardiac function within tolerated doses. Omecamtiv Mecarbil effectively relieves symptoms and enhances the quality of life of systolic heart failure patients. It drastically improves cardiac performance in the short term, however the hopeful long term effects of reduced mortality have yet to be studied.[2][1]

Diet Pill Dilemma: Why Is FDA Approving Drugs When Europe Isn’t?


2day929/flickr

We’ve all dreamt of popping a pill to help us safely lose weight, or at least eat that chocolate cake without guilt. But alas, even though the Food and Drug Administration has approved two new diet drugs in recent months, that dream probably isn’t any closer to reality.

In the current issue of the BMJ (formerly the British Medical Journal), Sidney Wolfe, founder of the advocacy group Public Citizen, slams the FDA for approving the drugs – lorcaserin (US brand name Belviq) and topiramate (called Qsymia). The FDA’s European counterpart rejected both of them because of heart risks that turned up during preliminary trials.

One Woman’s Ayurvedic Experience

by Jodi Boone

Over a cup of tea, she told me how they found her tumour. Mira, a middle-aged woman with large blue eyes and a gentle smile, holds a Ph.D. in Organizational Development and works as an administrator for the Swedish Army.

She explained how the stress and long hours of her work had culminated in 25 kilos of extra weight and high blood pressure. “For 20 years, I didn’t have time for myself – no time for exercise and no energy to shop or cook meals at home,” Mira said. Devoted to her studies in her 20’s and later to her career, Mira acknowledged that her trip to India in 2010 was the first time in her life she’d taken to focus on her health.

“I’d never been to India before, and I’d never heard of Ayurveda,” said Mira. One evening, as she searched…

Fruit Lowers the Risk of Diabetes


Medial Revolt's avatarMedical Revolt

English: Fruit stall in a market in Barcelona,...

The press is all over a recent study done at the Harvard school of public health that was published in the British Medical Journal last week. The study showed that those that ate fruit had a lower risk of diabetes. Specifically they singled out blueberries for a 25% reduction in risk. Grapes offered 11%, apples 5%, prunes 11%, pears 7%. This was not a randomized trial so there are a lot of uncontrolled variables but that being said they did look at 187,382 patients so that sample size does give this study a lot of weight. It also brings further support to a recommendation I have been giving to my diabetic or pre-diabetic patients for years, become a vegan and forget about the ADA (American Diabetes Association) diet.

A study done in 2006 published in Diabetes Care compared patients on a Vegan diet to patients on the ADA diet. The Vegan diet patients…
