Non-small Cell Lung Cancer Pancreatic Cancer Colorectal Cancer Loss of Appetite Fatigue Cachexia | Drug: ponsegromab Drug: Placebo for ponsegromab | Phase 2 |
A 12 week double blind study to evaluate the efficacy, safety and tolerability of ponsegromab compared to placebo in patients with cancer, cachexia, and elevated GDF 15.
During the initial 12-week treatment period (Part A), a total of 3 doses of ponsegromab or placebo will be administered 4 weeks apart subcutaneously. Each dose contains two injections. Part B is an optional open-label treatment period consisting of ponsegromab administered every 4 weeks subcutaneously for up to one year. Part B does not include placebo.
Assessments include:
- Body weight measurements
- Measure the impact of ponsegromab compared to placebo on physical activity.
- Measure the impact of ponsegromab compared to placebo on appetite, nausea and fatigue questionnaires
- Blood samples to evaluate safety and additional endpoints including the amount of study drug in the blood and the effects of the study drug on levels of GDF-15

- Change from baseline in body weight for ponsegromab compared to placebo [ Time Frame: baseline, Week 12 ]
- Change from baseline in physical activity as measured with remote digital sensors [ Time Frame: baseline, Week 12 ]evaluation of physical activity (Sedentary, light and moderate) and gait speed.
- change from baseline in Functional Assessment of Anorexia-Cachexia Therapy (FAACT-ACS and FAACT-5IASS) scores [ Time Frame: baseline, Week 12 ]FACT-G score sums 27 items; ACS score sums 12 items; both use a 5-point scale (0-4).Higher scores are associated with a higher health-related quality of life.
- Change from baseline in anorexia/appetite; Nausea and vomiting; and Fatigue as measured by the Cancer Related Cachexia Symptom Diary (CRCSD) [ Time Frame: baseline, Week 12 ]Self-reported questionnaire that measures severity of symptoms related to cancer cachexia: appetite, nausea, vomiting, and fatigue.
- Incidence of adverse events [ Time Frame: Week 12 ]
- Incidence of lab abnormalities [ Time Frame: Week 12 ]
- Incidence of vital sign abnormalities [ Time Frame: Week 12 ]
- Incidence of ECG abnormalities [ Time Frame: Week 12 ]
