Official Title

Nanocrystalline Megestrol Combined with Immunochemotherapy As First-Line Treatment for Cachexia in Extensive-Stage Small Cell Lung Cancer: a Patient-Centered Phase II Study

Brief Summary

This study hypothesizes that nanocrystalline megestrol acetate can improve the cachexia condition in patients and enhance the efficacy of immunochemotherapy regimens. It plans to enroll patients newly diagnosed with extensive-stage small-cell lung cancer (ES-SCLC) who are in the pre-cachexia or cachexia stage of the cachexia trajectory. These patients will receive first-line standard immunochemotherapy combined with nanocrystalline megestrol acetate intervention. Compared to the use of the first-line standard immunochemotherapy regimen alone, the study will monitor changes in body weight and body composition, which are nutritional status indicators relative to baseline, to assess whether these changes can translate into improved survival benefits and enhanced quality of life for patients.

The objective of this clinical study are：1.To assess the change in body weight relative to baseline in malignant patients with ES-SCLC treated with a first-line standard immunochemotherapy regimen during treatment with a simultaneous co-administration of nanocrystalline megestrol supportive intervention, compared to standard treatment. 2.To assess the impact of simultaneous co-administration of nanocrystalline megestrol supportive intervention during treatment with a first-line standard immunochemotherapy regimen, compared to standard treatment, on survival benefit and quality of life in patients with ES-SCLC malignancy. 3.To explore the improvement in inflammatory and nutritional markers and changes in lymphocyte subpopulations in patients with ES-SCLC malignant disease with simultaneous co-administration of nanocrystalline megestrol supportive intervention during treatment with a first-line standard immunochemotherapy regimen, compared to standard treatment.

Detailed Description

This study employed a Phase II adaptive umbrella trial , aiming to enrich patients with ES - SCLC in the pre - cachexia or cachexia stage and provide them with the opportunity to receive potentially effective megestrol acetate treatment. To expand the scope of patients receiving treatment and enhance the understanding of the benefit - risk profile in a broader population, we established two cohorts: the criteria - fulfilled (CF) cohort, where patients need to meet all inclusion and exclusion criteria; and the compassionate use (CU) cohort, where patients meet the inclusion criteria and major exclusion criteria but may not meet the minor exclusion criteria. Concurrently, a prospective real - world study (RWS) was initiated to observe the clinical outcomes of patients in the pre - cachexia/cachexia stage receiving physician - selected treatment (PTOC).

The CF cohort plans to enroll 200 subjects, with liver metastasis (yes vs no), cachexia stage (pre - cachexia vs cachexia), and ECOG PS (0 - 1 vs 2) as stratification factors. These subjects will be randomly assigned to 2 treatment groups at a 1:1 ratio:

1. Nano - Megestrol Group: Nanocrystalline megestrol (QD, up to 12 weeks) + tislelizumab (Q3W, 4 cycles) + chemotherapy (carboplatin + etoposide, Q3W, 4 cycles);
2. Standard Control Group: Tislelizumab (Q3W, 4 cycles) + chemotherapy (carboplatin + etoposide, Q3W, 4 cycles).

In the CU cohort, the treatment plan and visits are consistent with the nanocrystalline megestrol group in the criteria - fulfilled (CF) cohort.In the RWS cohort, immunotherapy can use PD - 1/PD - L1 inhibitors other than tislelizumab, and other drugs are consistent with the nanocrystalline megestrol group in the criteria - fulfilled (CF) cohort.

CU and RWS groups do not set a specific number of subjects to be enrolled.

   Referring to the 2016 ESPEN consensus on terminology, the following conditions are also met:

   • Maximum weight loss <5% relative to baseline 6 months ago;

     • Anorexia (presence of anorexia complaints or anorexia/malignant condition subscale FAACT-A/CS score ≤37); (iii) Serum C-reactive protein CRP ≥ 5 mg/L. Diagnostic criteria for cachexia Any one of the following conditions combined with loss of appetite or systemic inflammatory response.

   Involuntary weight loss >5% in the last 6 months. ② Weight loss >2% when BMI <18.5kg ③ Weight loss >2% with muscle loss.

9. Determine good organ function by the following requirements:

   a) Routine haematology (no supportive therapy with any blood components and cell growth factors within 7 days prior to initiation of study treatment): i. Absolute neutrophil ANC ≥ 1.5 × 10^9/L (1,500/mm3); ii. Platelet count ≥ 100 × 10^9/L (100,000/mm3); and iii. Haemoglobin ≥ 90 g/L.

   b) Renal function: i. Creatinine clearance* (CrCl) calculated ≥ 50 mL/min

   * The Cockcroft-Gault formula will be used to calculate CrCl (Cockcroft-Gault formula) CrCl (mL/min) = (140 - age) × weight (kg) × F}/ (SCr (mg/dL) × 72) F = 1 for males; F = 0.85 for females; SCr = serum creatinine. ii. urine protein ≤ 1+ or 24-hour (h) urine protein quantitatively < 1.0 g. c) Liver function: i. serum total bilirubin (TBil) ≤ 1.5 × upper limit of normal (ULN); TBil ≤ 3 × ULN for patients with liver metastases or evidence of confirmed/suspected Gilbert's disease.

AST and ALT ≤ 2.5 × ULN; for patients with liver metastases, AST and ALT ≤ 5 × ULN iii. serum albumin (ALB) ≥ 28 g/L d) Coagulation: International Normalised Ratio and Activated Partial Thromboplastin Time ≤ 1.5 × ULN (unless the patient is on anticoagulant therapy and the coagulation parameters (PT/INR and APTT) are in the expected range for treatment with anticoagulants at screening).

   e) Cardiac function: left ventricular ejection fraction (LVEF) ≥50%.

10. Lung function indices 1st second forced expiratory volume (FEV1) >1L or >30% of predicted value, and lung carbon monoxide diffusion function (DLCO) >30% of predicted value;

Female patients of childbearing potential must have a urine or serum pregnancy test (if the urine pregnancy test result is not confirmed negative, a serum pregnancy test is required, and the serum pregnancy result will be used as the basis for the negative result) performed within 3 days prior to the first dose of the drug, and the result is negative. If a female patient of childbearing potential engages in sexual intercourse with an unsterilised male partner, the patient must be using an acceptable method of contraception from the start of screening and must agree to continue to use the adopted method of contraception for a period of 120 days after the last dose of study drug; the decision on whether or not to discontinue contraception after this time point should be discussed with the investigator. If an unsterilised male patient has sexual intercourse with a female partner of childbearing potential, the patient must use an effective method of contraception from the start of screening until the 120th day after the last dose of study medication; discontinuation of contraception after this time point should be discussed with the investigator.
