CNN —New analyses of the longest clinical trial yet of the weight-loss drug Wegovy are shedding light on how quickly it helps people lose weight, how long they sustain that weight loss and how safe the medicine is over four years of use. A previous clinical trial showed even greater average weight loss for Wegovy: about 15% on average over 68 weeks, compared with 2.4% for people who got a placebo. It was sustained for up to four yearsThe results showed that the 10% average weight loss for people using Wegovy was sustained for up to 208 weeks, or four years. Patients stayed on the medicine while they sustained the weight loss. Almost 23% of people on Wegovy lost at least 15% of their body weight, compared with 1.7% on a placebo.
