Abstract
Background
Anamorelin is a selective ghrelin receptor agonist approved for cancer cachexia in Japan. Little is known about predictors of anamorelin efficacy. This study aimed to assess the effect of diabetes on the efficacy and safety of anamorelin in patients with cancer cachexia.
Methods
Medical records of patients with advanced non-small-cell lung, gastric, pancreatic, or colorectal cancer who received anamorelin between January 2021 and March 2023 were retrospectively reviewed. The diabetic (DM) group included patients with a confirmed diagnosis of type 2 diabetes mellitus, random plasma glucose of ≥ 200 mg/dL, or hemoglobin A1c of ≥ 6.5%. The maximum body weight gain and adverse events during anamorelin administration were compared between the DM and non-DM groups. Patients with a maximum body weight gain ≥ 0 kg were classified as the responders.
Results
Of 103 eligible patients, 31 (30.1%) were assigned to the DM group. The DM group gained less weight (median of −0.53% vs. + 3.00%, p < 0.01) and had fewer responders (45.2% vs. 81.9%, p < 0.01) than the non-DM group. The odds ratio for non-response in the DM group was 6.55 (95% confidential interval 2.37–18.06, p < 0.01), adjusted by age and performance status. The DM group had a higher cumulative incidence of hyperglycaemic adverse events (72.2% vs. 6.3%, p < 0.01) and more discontinuations due to hyperglycaemic adverse events (25.8% vs. 4.2%, p < 0.01) than the non-DM group.
Conclusions
Patients with diabetes and cancer cachexia are less likely to gain weight with anamorelin despite a high risk of hyperglycaemic adverse events.
