(Reuters) -Cytokinetics Inc said on Tuesday the U.S health regulator
declined to approve its oral drug for a type of heart failure, citing
lack of sufficient data to show the drug was effective, and sending
shares down 3% after the market trade. The U.S. Food and Drug
Administration's decision comes after a panel of outside experts in
December recommended against allowing the use of the drug due to safety
concerns.
The health regulator in its so-called "complete response letter" said
the company needs to have an additional trial of the drug, omecamtiv
mecarbil, to establish its effectiveness for the treatment of heart
failure due to reduced ejection fraction, the company said.
The chronic condition is caused by abnormal contractions in the main
pumping chamber of the heart.
Cytokinetics' application to the FDA was based on results from a
late-stage study of more than 8,000 patients in which the drug met trial
goals of reducing the risk of heart-failure related death or the need
for hospitalization and other urgent care.
The regulator's decision is a setback to the company that had long been
waiting for a nod on its drug, omecamtiv mecarbil, after the FDA
extended its review period in June.

Piper Sandler analyst Yasmeen Rahimi
said in December Cytokinetics should divert its resources to its
other late-stage heart drug, aficamten, which she believes has a
better probability of approval.
Late-stage data from aficamten's trial as a treatment for another
heart condition known as hypertrophic cardiomyopathy is due later
this year.
The company is prepared to redirect its focus to aficamten and other
drugs in its pipeline, in the event that the FDA rejected omecamtiv
mecarbil, Chief Executive Officer Robert Blum told Reuters in an
interview before the decision.
