Pfizer's ponsegromab met its primary endpoint in a Phase 2 trial, demonstrating a statistically significant increase in body weight compared to placebo in cancer cachexia patients.
The highest dose of ponsegromab (400 mg) led to a 5.61% mean increase in body weight at 12 weeks, along with improvements in appetite, cachexia symptoms, physical activity, and muscle mass.
The study included patients with non-small cell lung cancer, pancreatic cancer, or colorectal cancer, showing the drug was generally safe and well-tolerated across all dose levels.
Pfizer plans to initiate registration-enabling studies in 2025 based on these positive Phase 2 results, with ponsegromab also under investigation for heart failure.
