Patients who took an experimental drug from Eli Lilly & Co. together with Novo Nordisk A/S’s Wegovy maintained muscle while losing weight, offering a potential solution to one of the key problems that’s emerged with popular obesity shots.

Some doctors are concerned that patients taking weight loss drugs like Wegovy may be losing too much lean mass. A combination therapy might change that.

Danish drugmaker Novo Nordisk on Tuesday launched its blockbuster weight-loss drug Wegovy in India, three months after Eli Lilly began marketing its rival product Mounjaro in the world's most populous nation.
