Antag Therapeutics raises 80 million euros to advance its GIP-inhibiting weight loss drug AT-7687 into clinical testing, exploring its combination with Novo Nordisk's Wegovy. The Series A round, led by Versant Ventures, includes Novo Holdings, SR One, Pictet, KKR-related entities, Broadview Ventures, and the Danish Export and Investment Fund. Antag's approach contrasts with Eli Lilly's GIP-activating Zepbound, with both methods debated. Combining GIP with GLP-1 appears more effective than GLP-1 alone, as seen in Lilly's SURMOUNT-5 trial. Antag's AT-7607, a GIP-blocking peptide, aims for fewer side effects and potential synergies with current and future therapies.
