Novo Nordisk said on Monday it would halt its collaboration with U.S. telehealth company Hims & Hers Health over the distribution of the Danish company's blockbuster Wegovy weight loss drugs. The two companies had announced a collaboration in April for Hims & Hers to sell Wegovy through a bundled offering on the telehealth company's platform.

Novo Nordisk’s new weight-loss drug helped patients lose even more weight on average than its current Wegovy blockbuster treatment, an early-stage trial showed, as the drugmaker races to develop the next generation of obesity medicines.

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.
