Cachexia-directed therapy (GDF-15 blockade)
Treating the wasting that kills many cancer patients, by blocking the hormone that suppresses appetite.
GDF-15 rises in advanced cancer and acts on the brainstem to suppress appetite. Pfizer's ponsegromab, a GDF-15 antibody, improved weight in a phase 2 in patients with elevated GDF-15 (NCT05546476, completed) and has moved into a phase 2/3 programme in pancreatic cancer-associated cachexia (NCT06989437, recruiting since October 2025), with a further lung cancer study planned (NCT07663630). Cachexia has no approved disease-modifying therapy, so a positive phase 3 would be a first.
How it works
Neutralising circulating GDF-15 removes the anorexigenic signal at the GFRAL receptor in the hindbrain, restoring appetite and lean mass.
- Addresses a cause of death and of treatment discontinuation, not the tumour
- Clear biomarker for patient selection
- Phase 2 met its weight endpoints
- Weight gain must translate into function and survival
- Cachexia is multifactorial; GDF-15 is one pathway
- Phase 3 data pending
