Brief Summary

Patients with advanced lung cancer are a high-risk population for cancer-related anorexia-cachexia syndrome (CACS). Meanwhile, the adverse reactions of chemotherapy and immunotherapy potentially exacerbate the occurrence and progression of CACS. CACS seriously affects the quality of life of patients with advanced lung cancer, significantly shortens the overall survival (OS) and progression-free survival (PFS), forming a vicious cycle. A number of previous studies have shown that combined supportive therapies such as megestrol acetate during chemotherapy or concurrent chemoradiotherapy for advanced tumor patients is a clinically meaningful and feasible treatment model in clinical practice. However, the efficacy and optimal treatment timing of combination with current first-line immunochemotherapy regimens remain unclear. Although mechanistic studies have shown that anti-cachexia therapy may synergistically enhance the efficacy of immunotherapy, relevant clinical research evidence is lacking. Therefore, this study hypothesizes that the combination of first-line immunochemotherapy regimen and nano-crystalline megestrol acetate can improve the clinical benefits of patients with advanced lung cancer. It is planned to enroll patients with advanced lung cancer who present with anorexia-cachexia, and administer nano-crystalline megestrol acetate intervention (nano-crystalline megestrol acetate or its placebo control) during first-line immunochemotherapy. The changes in body weight relative to the baseline, as well as the impact on survival benefits and quality of life of patients, will be detected. In China, megestrol acetate is mainly available in two dosage forms: oral suspension and dispersible tablets. The oral suspension of megestrol acetate adopts nano-crystal technology (referred to as nano-crystalline megestrol acetate), which reduces the particle size of megestrol acetate and improves bioavailability. Previous randomized controlled studies have shown that it is superior to non-nano-crystal dosage forms in improving body weight.

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients must meet all the following criteria to be eligible for study enrollment:
• Patients with histologically or cytologically confirmed locally advanced (Stage ⅢC) or metastatic (Stage IV) non-small cell lung cancer (NSCLC) that cannot be completely resected surgically or treated with radical chemoradiotherapy, according to the 8th edition of the TNM staging classification for lung cancer by the International Association for the Study of Lung Cancer and the American Joint Committee on Cancer Classification.
• Patients with histologically or cytologically confirmed small cell lung cancer (SCLC) and diagnosed as extensive-stage SCLC based on the 8th edition of AJCC staging or the Veterans Administration Lung Group (VALG) criteria (excluding mixed small cell lung cancer).
• Subjects who have not received prior systemic chemotherapy for metastatic disease. Subjects who received adjuvant/neoadjuvant chemotherapy or radical concurrent/sequential chemoradiotherapy with curative intent for non-metastatic disease are eligible if disease progression occurs \>6 months after the end of the last treatment.
• At least one measurable tumor lesion according to RECIST v1.1.
• Criteria for pre-cachexia or cachexia stage:
• Pre-cachexia diagnostic criteria (all three must be met):
• Unintentional weight loss ≤5% in the past 6 months;
• ② Systemic inflammation (CRP \>5 mg/L);
• ③ Decreased appetite (FAACT-A/CS 12 score ≤37).
• Fearon diagnostic criteria for cachexia stage (any one of the following combined with decreased appetite \[FAACT-A/CS 12 score ≤37\] or systemic inflammation \[CRP \>5 mg/L\]):
• Unintentional weight loss \>5% in the past 6 months; ② Weight loss \>2% when BMI \<18.5 kg/m².
• Good compliance and signed informed consent form.
• Age 18-75 years, regardless of gender.
• ECOG performance status 0-2.

You may not qualify if:

• a) Active or untreated CNS metastases (e.g., brain or leptomeningeal metastases) confirmed by CT or magnetic resonance (MRI) evaluation during screening and prior imaging. Patients who have received treatment for brain or leptomeningeal metastases, have been stable for ≥2 months, and have discontinued systemic hormonal therapy (\>10 mg/d prednisone or equivalent) \>4 weeks before randomization may participate.
• b) Uncontrolled tumor-related pain. c) Thromboembolic disease, ascites, or lower limb edema within the past 6 months.
• d) History of malignant tumors other than lung cancer within 5 years before randomization, except for malignancies with negligible risk of metastasis or death \[e.g., expected 5-year overall survival rate \>90%\] and expected to be cured after treatment, such as appropriately treated cervical in situ carcinoma, basal or squamous cell skin cancer, localized prostate cancer treated with radical surgery, and ductal carcinoma in situ treated with radical surgery.
• Women who are pregnant, lactating, or planning to become pregnant during the study.
• Patients with hepatitis B (known HBsAg-positive and HBV DNA ≥1000 cps/ml or 200 IU/ml or ≥ the upper limit of normal at each study center) or hepatitis C:
• ● For patients with a history of HBV infection, HBV DNA testing must be performed, and they are eligible only if HBV DNA is negative (HBV DNA \<1000 cps/ml or 200 IU/ml or below the upper limit of normal).
• Among patients with positive HCV antibody, only those with negative HCV RNA by polymerase chain reaction (PCR) may participate.
• Patients with positive human immunodeficiency virus (HIV) test results.
• Receipt of major surgery (excluding diagnostic surgery) within 28 days before randomization, or expected to undergo major surgery during the study.
• Significant cardiovascular diseases, such as heart disease defined by the New York Heart Association (class II or higher), myocardial infarction within 3 months before randomization, unstable arrhythmia, unstable angina, cerebrovascular accident, or transient ischemic attack. Patients with known coronary artery disease, congestive heart failure not meeting the above criteria, or left ventricular ejection fraction \<50% must receive the optimal stable treatment regimen as determined by their attending physician, with consultation from a cardiologist if necessary.
• Severe infection within 4 weeks before the first drug administration, including but not limited to complications requiring hospitalization, sepsis, or severe pneumonia; active infection requiring systemic anti-infective therapy within 2 weeks before the first drug administration (excluding antiviral therapy for hepatitis B or C).
• <!-- -->
