Brief summary
This study aims to evaluate the efficacy of the oral postbiotic preparation JK-5G in improving body weight among patients with non-small-cell lung cancer (NSCLC)-related cachexia. By means of a randomized controlled trial, we will compare the between-group difference in body-weight changes between the JK-5G and placebo arms to clarify its nutritional therapeutic benefit.
Interventions
Postbiotics oral powder, 2.5 g per dose, administered three times daily for a total duration of 90 days (four 21-day chemotherapy cycles).
Placebo made of cyclodextrine, oral powder, 2.5 g per dose, administered three times daily for a total duration of 90 days (four 21-day chemotherapy cycles).
