A good number of preclinical and early clinical studies have shown evidence for both approaches, particularly for Ponsegromab, a Growth Differentiation Factor-15 (GDF-15) inhibitor. Due to the multifactorial nature of cachexia, a multimodal, integrated intervention is a good substitute for the maximum tolerated dose, which can be effective against it. Future directions in cancer therapy should emphasize the development of robust clinical trial designs with cachexia-specific endpoints to advance precision prevention strategies.
These dimerized protein mimetics inhibited cell signaling in a functional assay and showed improved pharmacokinetic properties compared with their monomeric counterparts. This is the first example of a homodimeric Bicycle molecule inhibiting receptor complex formation, thereby antagonizing the intracellular signaling response.
The conference also highlighted promising clinical advancements, including the HIPGEN trial on placental-expanded stromal cells for muscle regeneration in hip fracture patients and the ponsegromab study targeting growth/differentiation factor-15 inhibition to mitigate cancer cachexia-associated muscle wasting. This review highlights the integration of basic science, innovative diagnostics, and clinical applications as a promising framework for addressing the complex challenges posed by muscle-wasting disorders. As the field progresses, these insights offer hope for improving the quality of life and survival of affected patients.
Targeting the GDF15-GFRAL axis appears therapeutically promising: the monoclonal antibody ponsegromab improved cachexia-related outcomes in the PROACC-1 trial, while visugromab combined with nivolumab enhanced immune response in ICI-refractory tumors. Further investigation is warranted to delineate the role of GDF15 across malignancies, refine patient selection, and evaluate combinatorial approaches with existing treatments.
