Clinical Study on Nanocrystalline Megestrol Acetate for Appetite Improvement and Weight Gain in Pre-Cachexia and Cachexia Stages Key Terminology Analysis

Clinical Study on Nanocrystalline Megestrol Acetate for Appetite Improvement and Weight Gain in First-Line Non-Squamous Non-Small Cell Lung Cancer Patients During Pre-Cachexia and Cachexia Stages.

The purpose of this study is to evaluate the efficacy and safety of nanocrystalline medroxyprogesterone acetate for improving appetite and weight gain patients with non-small cell lung cancer (NSCLC) and cachexia and pre-cachexia. The enrolled patients were those with advanced NSCLC who had not received therapy, negative for driver genes and ineligible for curative treatment, and were planned to receive PD-1 inhibitors in combination with platinum-based chemotherapy.

Inclusion Criteria:

• ≥18 years at the time of enrollment.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2.
• Life expectancy ≥6 months.
• Histologically or cytologically confirmed metastatic (stage IV) driver gene-negative non-squamous non-small cell lung cancer (NSCLC) that is unresectable and not amenable to curative therapy
• Subjects with no prior systemic chemotherapy for metastatic non-small cell lung cancer (NSCLC).

Exclusion Criteria:

• Presence of any gastrointestinal absorption-impairing conditions (e.g., dysphagia, malabsorption, prior gastrectomy, or uncontrolled vomiting); current use of tube feeding/parenteral nutrition; or existence of anorexia nervosa, psychiatric disorder-induced anorexia, or pain-related feeding intolerance.
• Driver gene-positive NSCLC or histologically/cytologically confirmed squamous cell-dominant NSCLC.
• Patients with Cushing's syndrome, adrenal/pituitary insufficiency; poorly controlled diabetes mellitus.
• Concurrent enrollment in another clinical trial, unless it is an observational/non-interventional study or the follow-up phase of an interventional trial.
