AbbVie Aims for Psychedelic Depression Treatment Market with $1.2 Billion Agreement
AbbVie Acquires Depression Drug: AbbVie will purchase an experimental depression drug from Gilgamesh Pharmaceuticals for up to $1.2 billion, aiming to enter the growing market for psychedelic-based treatments.
Significant Investment in Acquisitions: This deal is part of AbbVie's strategy, which has seen over $20 billion spent on acquisitions since 2023, particularly as its main product, Humira, has lost patent protection.
Potential Market Growth: The partnership with Gilgamesh could position AbbVie in a potential $50 billion market for psychedelic compounds aimed at treating psychiatric conditions, following the FDA's approval of Johnson & Johnson's ketamine-derived treatment earlier this year.
Bretisilocin's Therapeutic Benefits: Gilgamesh's lead candidate, bretisilocin, targets the 5-HT2A serotonin receptor and has shown promise in early studies for providing therapeutic benefits with a shorter psychoactive experience, leading AbbVie to advance it into late-stage studies.
