Strategic Initiatives
Growth programs, investments, and their expected impact
Refocusing resources across the portfolio to optimize promotional efforts for INPEFA in heart failure while prioritizing investment and preparation for the potential commercial launch of ZYNQUISTA in type 1 diabetes.
Expected impact: Expected to reduce operating costs by approximately $40 million annually, improving operational efficiency and ensuring late-stage R&D programs are fully funded.
Concentrating internal research and development capabilities on core strengths in cardiometabolic disease (sotagliflozin in heart failure, type 1 diabetes, and HCM) and chronic neuropathic pain (pilavapadin/LX9211).
Expected impact: Advancing high-potential, first-in-class assets to regulatory milestones while seeking external development partners for non-core or high-cost trials (such as Phase 3 trials for pilavapadin).
