A Phase I Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetic Characteristics, and Preliminary Efficacy of SXRN Injection in Patients With Cancer Cachexia

Recruiting now · Phase 1

Conditions studied: Cachexia-Anorexia Syndrome, Solid Tumor Malignancies

In brief

This is a clinical study evaluating the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of SXRN Injection in cancer patients with anorexia-cachexia. Phase Ia employs a single-arm, open-label, dose-escalation design. Phase Ib, an extension of the study, utilizes a design of combination therapy with standard anti-tumor therapy for cancers including but not limited to pancreatic cancer, non-small cell lung cancer (NSCLC), and colon cancer.

• ① >5% involuntary weight loss within the past 6 months; or >2% weight loss if BMI <18.5 kg/m²; or >2% weight loss in the presence of reduced muscle mass;
• ② Anorexia (VAS score ≤70, or FAACT-A/CS score ≤37);
• ③ CRP >5 mg/L;
• 4. (Phase Ia only) Cancer patients who have failed or are intolerant (experienced drug-related ≥ Grade 4 hematologic toxicity, or ≥ Grade 3 non-hematologic toxicity) to prior standard therapy, or lack effective conventional treatment options;
• 5. (Phase Ib only) Patients requiring standard anti-tumor drug therapy per CSCO guidelines of advanced pancreatic cancer, non-small cell lung cancer, colorectal cancer, or other eligible solid tumors;
• 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2;
• 7. Life expectancy ≥12 weeks.
• 8. Laboratory test results and organ function assessed within 7 days prior to the first dose must meet the following criteria:
• Blood routine: 1)Absolute Neutrophil Count (ANC) ≥1.5×10\^9/L;2)Platlets (PLT) Count≥75×10\^9/L; 3)Hemoglobins (Hb) ≥80 g/L.
• Note: the criteria above shall still be maintained within 14 days before the initial infusion, either without the need of blood transfusion, or using supportive treatment including granulocyte colony-stimulating factor (G-CSF), thrombopoietin (TPO), interleukin-11 (IL-11), and erythropoietin (EPO), and etc.
• Blood biochemistry: 1)Total bilirubin (TBIL) ≤3.0 × upper limit of normal (ULN); 2)Serum creatinine (SCr) ≤1.5 × ULN or creatinine clearance (CrCl) by Cockroft Gault formula ≥30 mL/min; 3)Aspartate Amino Transferase (AST), Alanine Aminotransferase (ALT) ≤3×ULN; for participants with liver metastasis, AST, ALT≤5.0×ULN, and ALP≤6.0×ULN; d)Albumin (ALB) ≥30g/L.
• Urine routines: Urine protein ≤2+ (if >2+, 24-hour urine protein quantification must be performed, and total protein ≤1 g is required for eligibility).
• Blood coagulation: International Normalized Ratio (INR), Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT) ≤1.5×ULN.
• Note: for subjects receiving precautious anti-coagulation treatment, the investigator shall determine whether INR and APTT remains in a safe and effective range for treatment.
• Ultrasonic cardiogram: Left Ventricular Ejection Fraction (LVEF) ≥50%.
• 9.The participant must be able to understand and voluntarily sign the written Informed Consent Form (ICF); and must be willing and able to comply with all study procedures and follow-up examinations.

You may not qualify if…

• Participants meeting any of the following criteria shall be excluded from the study:
• 1. Reversible causes of reduced food intake as determined by the investigator, which may include but are not limited to mechanical obstruction preventing adequate oral intake;
• 2. Use of any prescription medication intended to improve appetite or mitigate weight loss within 28 days or 5 half-lives of the drug (whichever is shorter) prior to the first dose of the investigational product, including but not limited to anamorelin, megestrol acetate, cannabinoids, or medical marijuana;
