Investors looking for midteen percentage weight loss findings in Zealand Pharma A/S’s phase II study of once-weekly amylin analogue petrelintide were clearly disappointed by the actual 10.7% mean body weight reduction, as shares (Copenhagen:ZEAL) fell 36% March 6. But from the company’s standpoint, the combination of efficacy and safety data from the Zupreme-1 study bode well for a phase III trial expected to start later this year.
Although cagrilintide from Novo Nordisk A/S proved less than impressive when paired with GLP-1 agonist semaglutide in a single drug known as Cagrisema, the dual long-acting amylin analogue and calcitonin receptor agonist is looking good as a monotherapy in a subanalysis of the phase III Redefine-1 trial.
One of the big questions going into the phase I readout for Metsera Inc.’s amylin analogue, MET-233i, was whether findings would support once-monthly dosing for the potential obesity candidate. They did. Results also indicated solid and dose-dependent weight loss activity, and Metsera was able to identify well-tolerated starting doses for subsequent studies, said Steve Marso, chief medical officer. “So we exceeded expectations on all three scientific objectives.”
