Pfizer Presents Positive Data from Phase 2 Study of Ponsegromab in Patients with Cancer Cachexia
- Study met primary endpoint of change from baseline in body weight for ponsegromab compared to placebo across all ponsegromab doses tested, reaching 5.6% mean increase at the highest dose evaluated at 12 weeks; ponsegromab was generally considered safe and well-tolerated at all dose levelsi
- At the highest dose evaluated, improvements were seen from baseline in appetite and cachexia symptoms, physical activity, and muscle massi
- Based on positive Phase 2 results, registration-enabling studies will start in 2025
“Cachexia is a common condition in cancer patients, associated with weight loss, functional decline, and ultimately poor outcomes. Despite the number of people suffering from cachexia, there are no available options for us to help treat patients,” said
The Phase 2 study included 187 participants with non-small cell lung cancer, pancreatic cancer, or colorectal cancer. Ponsegromab demonstrated significant and robust increases in body weight after 12 weeks across all doses: 2.02% (95% confidence interval (CI), -0.97 to 5.01%) in the 100 mg treatment group, 3.48% (95% CI, 0.54 to 6.42%) in the 200 mg group, and 5.61% (95% CI, 2.56 to 8.67%) in the 400 mg group, compared to placebo. Improvements across multiple domains of the cachexia phenotype were observed in the 400 mg group including in measures of appetite and cachexia symptoms, physical activity and skeletal muscle index. No clinically significant adverse trends were noted with ponsegromab administration. Treatment related adverse events occurred in 8.9% of patients taking placebo and 7.7% of patients taking ponsegromab.i

About the Phase 2 Trial in Cancer Cachexia
The primary objective of the Phase 2 study (NCT05546476) is to assess the effect of ponsegromab on body weight in patients with cancer (non-small cell lung cancer, pancreatic cancer or colorectal cancer), cachexia and elevated serum GDF-15 concentrations (>1500 pg/mL). Secondary and exploratory endpoints objectives included measures such as: Change from baseline in appetite and cachexia symptoms, digital measures of physical activity, and changes in lumbar skeletal muscle index (LSMI). Patients (n=187) received either ponsegromab (100 mg, 200 mg or 400 mg) or placebo once every four weeks subcutaneously for 12 weeks.
About Cachexia
Cachexia is a complex, disabling, and life-threatening metabolic condition that is estimated to affect about 9 million people worldwide.ii Symptoms such as weight and muscle loss can reduce patients’ ability to tolerate treatment for their underlying chronic diseases, such as cancer and heart failure, and can severely impact quality of life.ii,iii In cancer, cachexia can diminish the efficacy of cancer treatments and is thought to contribute to decreased survival rates and may cause up to 30% of cancer-related deaths.iv Despite its severity, there are no FDA-approved treatments for cachexia.iii
About Ponsegromab
Ponsegromab is an investigational monoclonal antibody designed to treat cachexia by targeting GDF-15. Prior Phase 1b data in participants with cancer cachexia demonstrated proof-of-mechanism for ponsegromab with robust suppression of unbound circulating GDF15 levels observed. The results showed encouraging signals of efficacy that included increases in body weight and encouraging improvements in patient reported outcomes.

Disclosure Notice
The information contained in this release is as of
This release contains forward-looking information about ponsegromab, an investigational monoclonal antibody designed to treat cachexia, including its potential benefits and late-stage development planning, and Pfizer’s cardiometabolic portfolio, that involve substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Risks and uncertainties include, among other things, the uncertainties inherent in research and development, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for our clinical trials, regulatory submission dates, regulatory approval dates and/or launch dates, as well as the possibility of unfavorable new clinical data and further analyses of existing clinical data, including results from the Phase 2 study of ponsegromab in patients with heart failure; the risk that clinical trial data are subject to differing interpretations and assessments by regulatory authorities; whether regulatory authorities will be satisfied with the design of and results from our clinical studies; whether and when drug applications may be filed in any jurisdictions for any potential indication for ponsegromab or any other cardiometabolic product candidates; whether and when any such applications that may be filed for ponsegromab or any other such product candidates may be approved by regulatory authorities, which will depend on myriad factors, including making a determination as to whether the product's benefits outweigh its known risks and determination of the product's efficacy and, if approved, whether ponsegromab or any such other product candidates will be commercially successful; decisions by regulatory authorities impacting labeling, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of ponsegromab or any such other product candidates; uncertainties regarding the impact of COVID-19 on our business, operations and financial results; and competitive developments.
