ACT was a study to assess therapies to reduce the clinical progression of Coronavirus disease 2019 (COVID-19), evaluating combination of drugs to treat COVID-19 versus usual care in symptomatic outpatients and inpatients who have tested positive for COVID-19, across the spectrum of severity of the condition.
Two open-label, parallel group, randomized controlled trials – inpatient and outpatient – included adaptive intervention arms and adaptive sample size based on new and emerging data.
Primary outcome: Hospital admission or death.
Primary outcome: Composite of invasive mechanical ventilation or mortality.

Salim Yusuf is an internationally renowned cardiologist and epidemiologist, whose work over 40 years has substantially influenced prevention and treatment of cardiovascular disease. Born in India, medically qualified at St. John’s Medical College, Bangalore in 1976, he received a Rhodes Scholarship and obtained a DPhil from Oxford, during which he (along with Richard Peto, Rory Collins and Peter Sleight) initiated the concepts of large, simple trials, and meta-analysis. He proposed the concept of combination drug treatment for prevention of CVD to achieve large reductions in CVD with a single pill (now called the polypill concept), but more importantly has been evaluating the concept through large randomized trials.
He leads several global studies involving more than 60 countries in every inhabited continent of the world aimed at enhancing knowledge about the biological, behavioural and societal causes, consequences, and approaches to the control of heart diseases, and strokes through large multi-country programs such as INTERHEART, INTERSTROKE, and PURE.
He holds a Heart and Stroke Foundation of Ontario Research Chair and has received (among others) the Lifetime Research Achievement award of the Canadian Cardiovascular Society; the Paul Wood Silver Medal of the British Cardiac Society; the European Society of Cardiology gold medal, the clinical Research Prize of the American Heart Association and the International Award and the Braunwald Lecture of the American College of Cardiology. He has been inducted into the Royal Society of Canada and the Canadian Medical Hall of Fame; been appointed as an Officer of the Order of Canada, and received the Canada Gairdner Wightman Award in 2014. He has received four honorary doctorates, and is among the top 20 most cited health researchers in history.
Salim Yusuf has published more than 1,000 articles in refereed journals, rising to the second most cited researcher in the world for 2011. He has mentored more than 120 scientists, several of whom are in leadership positions across the globe. He has been President of the World Heart Federation (2015-2016), where he initiated several programs (the Emerging Leaders program, road maps for CVD control and a course for training primary care practitioners in CVD prevention) aimed at halving the CVD burden globally within a generation. The World Heart Federation has recognized his contributions by naming the program the Salim Yusuf Emerging Leaders Programme.
