Shares in two companies slide as Danish drugmaker accuses US telehealth group of deceptively marketing replica treatments

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.
