Combine the new anti-wasting antibody with exercise and protein

A new antibody blocks the hormone that makes people with cancer lose appetite and weight. Weight regained as muscle, not fat, needs exercise and protein alongside it.

GDF-15 is a tumour-derived hormone acting on the brainstem GFRAL receptor to suppress appetite, and a randomised phase 2 of the anti-GDF-15 antibody ponsegromab reported weight gain and improved appetite in cancer cachexia. Weight gain alone is not the goal: without a resistance training and protein stimulus, regained mass is likely to be fat rather than functional muscle.

Hypothesis
Anti-GDF-15 therapy combined with supervised resistance exercise and protein supplementation produces greater gains in lean mass and physical function than the antibody alone, at equal total weight gain.
Rationale
Anabolic signals are needed to direct nutrient partitioning into muscle, as shown by decades of sarcopenia and geriatric rehabilitation research. Function, not weight, is what determines whether patients can tolerate treatment and live independently.
What would test it
A factorial randomised trial of antibody with or without a structured exercise and nutrition programme, with lean mass by imaging and a physical function measure as co-primary endpoints.
