Abstract

Anamorelin, a ghrelin receptor agonist, is approved in Japan for the treatment of cachexia in patients with lung and gastrointestinal cancer. However, there is limited research on the usefulness of anamorelin in clinical settings, therefore, the present study evaluated its efficacy using patient characteristics. A total of 40 patients with non‑small cell lung cancer and cachexia who were prescribed anamorelin in the Department of Respiratory Medicine, Hirosaki University Graduate School of Medicine (Aomori, Japan) between July 2021 and November 2022, were retrospectively assessed. Anamorelin was prescribed at a dose of 100 mg once daily to patients who had lost >5% of their body weight within 6 months. All patients were weighed before treatment and those who continued anamorelin treatment for 12 weeks were also weighed at 12 weeks. A logistic regression analysis was used to analyze the association between background characteristics and early discontinuation of treatment with anamorelin (within 4 weeks). The median age was 67 years (range, 36‑88), and 65% of the patients were male. There were 24 patients (60.0%) with an Eastern Cooperative Oncology Group Performance Status (ECOG‑PS) score 1, 11 patients (27.5%) with an ECOG‑PS score 2 and five patients (12.5%) with an ECOG‑PS score 3. The early discontinuation group included 11 patients (27.5%). An ECOG‑PS score ≥2 (odds ratio, 7.85; 95% confidence interval, 1.43‑43.21; P=0.018) was associated with early discontinuation. A total of 18/40 patients (45.0%) were able to continue anamorelin treatment for 12 weeks, and the mean change in body weight was +2.31 kg, which was a significant change from the weight recorded at baseline (P=0.027). The mean changes in lean body mass and soft lean mass between baseline and 12 weeks were +1.97 kg (P=0.14) and +1.26 kg (P=0.15), respectively. The results from the present study indicate that anamorelin is unlikely to be useful for patients with a poor general condition (ECOG‑PS score ≥2).
