"Eli Lilly and Cos new Jardiance pill slashed deaths by  percent in patients with type  diabetes at risk of heart attack and stroke a finding that could make it a mainstay diabetes treatment and triple its use according to researchers and analysts.  Lilly shares jumped as much as  percent after data from the trial was released Thursday at a medical meeting in Stockholm.  This is the first diabetes therapy to show robust effect in reducing cardiovascular death. It really is big news said Dr. Bernard Zinman director of the Diabetes Centre at Mount Sinai Hospital in Toronto who led the threeyear study of  people.  Because about onehalf of the deaths in people with type  diabetes are caused by cardiovascular disease reducing cardiovascular risk is considered essential to diabetes care. Type  diabetes is the most common form of the disease and is linked to obesity.  Jardiance a onceaday pill which won U.S. approval last year belongs to a new family of treatments called SGLT inhibitors that include Johnson  Johnsons Invokana and AstraZeneca Plcs Farxiga. They lower blood sugar by inhibiting reabsorption of glucose in the kidneys.  Jardiance was developed jointly with Germanys privately held Boehringer Ingelheim.  Zinman in an interview predicted the new study would prompt medical societies to recommend that Jardiance be used by type  diabetics who have a history of heart disease or who are at risk of cardiovascular events.  About  million Americans have type  diabetes according to federal data for . The vast majority of those patients could be candidates for Jardiance which costs over  per year Morningstar analyst Damien Conover said.  The big news here is that the drug reduced cardiovascular stuff. That has not been the case with all things in diabetes said David Marrero president of health care and education at the American Diabetes Association. It is probably going to be a more popular drug because of that.  JARDIANCE COULD BOOST EARNINGS  Sanford Bernstein analyst Tim Anderson more than tripled his annual sales forecast for Jardiance and combination drugs containing it to . billion by . He cut his  sales forecast for Merck  Co Incs Januvia the leading member of a competing class of oral diabetes drugs called DPP inhibitors to  billion from . billion.  Anderson estimates Jardiance could boost Lillys earnings per share by  percent on average across  to .  In the study patients taking Jardiance had a  percent reduction in cardiovascular death including from heart attacks and strokes. There was no significant difference in nonfatal heart attacks or nonfatal strokes.  Those taking Jardiance had a  percent lower risk of dying from any cause and a  percent lower rate of hospitalizations from heart failure.  The benefits were especially impressive because they added to protection that patients received from taking cholesterol fighters and other lifesaving heart drugs Zinman said.  This is a wonderful thing said Dr. Jerome Tolbert of Mount Sinai Beth Israel Hospital in New York. He has not prescribed Jardiance and similar drugs as frequently as treatments like Januvia but expects that may change based on the new data.  Zinman noted that Jardiance like other SGLT drugs causes weight loss and reduced blood pressure besides lowering both blood sugar levels and body fat and also reduces swelling which all help the cardiovascular system.  Lilly and Boehringer last month disclosed that Jardiance met its primary study goal becoming the first diabetes drug to show heartprotective results in a large cardiovascular trial. But they did not unveil detailed data until Thursday at the medical meeting.  Shares of Lily closed up . percent at . on Thursday after rising as high as ..  In calculating the combined number of cardiac deaths nonfatal heart attacks and nonfatal strokes  percent fewer events were seen in patients taking Jardiance in combination with standard treatments compared with patients who took standard treatments alone meeting the studys main goal.  Standard treatments included statins which lower cholesterol and blood pressure drugs.
