Strategic Initiatives
Growth programs, investments, and their expected impact
Advancing once-weekly canvuparatide (MBX 2109) into a Phase 3 double-blind, placebo-controlled trial enrolling approximately 160 patients with chronic hypoparathyroidism [1.1.4].
Expected impact: Aims to establish canvuparatide as a highly differentiated, long-acting parathyroid hormone replacement therapy.
Developing a robust portfolio of once-monthly peptide therapeutics for obesity, including MBX 4291 (GLP-1/GIP), MBX 5765 (amycretin prodrug), and a triple-agonist candidate.
Expected impact: Positions the company to capture a share of the large metabolic and weight-loss market with highly convenient once-monthly dosing profiles.
Leveraging the appointment of Karen Basbaum as Chief Business Officer to actively pursue high-value strategic partnerships, licensing agreements, and potential M&A transactions.
Expected impact: Aims to de-risk late-stage clinical development, secure non-dilutive capital, and establish commercialization pathways.
