New antibodies against GDF-15 restored weight in early trials. Combine them with exercise and nutrition and test properly.","summary":"Cancer cachexia affects a large share of patients with pancreatic, lung and gastric cancer and contributes directly to death and treatment intolerance. Ponsegromab, an anti-GDF-15 antibody, increased weight and activity in a randomised phase 2 trial; ghrelin agonists (anamorelin) are approved in Japan. The proposal is a programme treating cachexia as an indication in its own right: standardised diagnosis and staging, a phase 3 of GDF-15 blockade with function and survival endpoints, and multimodal bundles combining pharmacotherapy with resistance exercise and nutritional support, embedded early in oncology care rather than at end of life.","asOf":"2026-09-08","links":[{"label":"Bottleneck evidence (Cachexia, toxicity and the limits of the patient): Fearon et al., Definition and classification of cancer cachexia (Lancet Oncology 2011)","url":"https://doi.org/10.1016/S1470-2045(10)70218-7"}],"tags":[],"related":[],"cancers":["pancreatic","nsclc","gastric"],"sections":[],"technologies":["exercise-oncology"],"targets":[],"drugs":[],"companies":["pfizer"],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-cachexia-supportive","b-toxicity-qol"],"keyPapers":["paper-fearon-lancet-oncol"],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"Early multimodal cachexia treatment improves physical function and chemotherapy completion and extends overall survival in pancreatic and lung cancer by a clinically meaningful margin.","rationale":"Cachexia is mechanistically driven (GDF-15, inflammation, anorexia signalling) rather than an inevitable consequence, and the first mechanism-based drug has shown activity.","test":"Phase 3 of GDF-15 blockade plus multimodal support versus standard care in newly diagnosed metastatic pancreatic and lung cancer with cachexia; endpoints weight, function, chemotherapy dose intensity and survival.","maturity":"early-clinical","actor":"industry","cost":"large","horizonYears":5},"route":"/ideas/idea-moon-cachexia-as-treatable-disease/","neighbours":{"cancer":[{"id":"gastric","kind":"cancer","name":"Gastric & gastro-oesophageal junction cancer","route":"/cancers/gastric/"},{"id":"nsclc","kind":"cancer","name":"Non-small-cell lung cancer","route":"/cancers/nsclc/"},{"id":"pancreatic","kind":"cancer","name":"Pancreatic ductal adenocarcinoma","route":"/cancers/pancreatic/"}],"technology":[{"id":"cachexia-appetite-pharmacotherapy","kind":"technology","name":"Cachexia pharmacotherapy: GDF-15 blockade, anamorelin, olanzapine","route":"/technologies/cachexia-appetite-pharmacotherapy/"},{"id":"exercise-oncology","kind":"technology","name":"Exercise & lifestyle oncology","route":"/technologies/exercise-oncology/"},{"id":"resistance-training-cachexia","kind":"technology","name":"Resistance training and protein for cachexia and sarcopenia","route":"/technologies/resistance-training-cachexia/"}],"company":[{"id":"pfizer","kind":"company","name":"Pfizer (incl.
