Phase I Clinical Trial on Tolerability and Bioavailability of Utidelone Capsule in Patients With Advanced Solid Tumors
This study has three parts. Part 1 is a dose-escalation trial, Part 2 is a pharmacokinetic comparison and food effect study, and Part 3 is extended trial of combination of utidelone capsule and capecitabine. The primary objectives are 1. To evaluate the safety and tolerability of utidelone capsules in patients with advanced solid tumors and to determine the Maximum Tolerated Dose (MTD) and Dose Limiting Toxicity (DLT). 2. To evaluate the objective response rate in patients with advanced metastatic breast cancer treated with the combination of utidelone capsule and capecitabine. The secondary objectives are: 1. to evaluate the absolute bioavailability of utidelone capsules relative to utidelone injection; 2. to evaluate the pharmacokinetic profile of utidelone capsules in patients with advanced solid tumors; 3. to preliminarily evaluate the efficacy and safety of utidelone capsules in patients with advanced solid tumors; and 4. to recommend doses and dosing regimens for subsequent clinical trials. 5. To evaluate the Progression-Free Survival (PFS), safety and pharmacokinetics of utidelone capsule combined with capecitabine in the treatment of patients with advanced metastatic breast cancer.
‣ Subjects must meet all of the following criteria to be enrolled into the study:
• Patients who have fully understood the objectives, content, process of the study and possible adverse events, voluntarily serves as a subject and signs the informed consent form.
• Part 1 and Part 2: Patients with definitive histopathological diagnosis of advanced solid tumors. Part 3: Patients were diagnosed with advanced metastatic breast cancer by pathology and/or cytology.
• Part 1 and Part 2: Male or female subjects aged ≥18 and ≤65, Part 3: Male or female subjects aged ≥18 and ≤70, with ECOG performance status scored 0-1.
• Expected survival time ≥ 12 weeks;
• At least one measurable lesion present according to RECIST 1.1 criteria.
• Baseline routine blood tests within 1 week prior to enrollment is normal (not received blood transfusions or hematopoietic-stimulating factors within 14 days), with CTCAE grade ≤1 (based on normal values at each site's laboratory): a) Neutrophil count (ANC) ≥ 1.5 × 109/L; b) platelet count (PLT ) ≥ 100 × 109/L; c) Hemoglobin ≥9.0 g/dL.
• Liver and kidney function test results are normal within 1 week prior to enrollment, with CTCAE grade ≤1 (based on normal values at each site's laboratory): a) Total bilirubin (TBIL) ≤ 1.5× the upper limit of normal value (ULN); b) Serum Glutamic Pyruvic Transaminase/Alanine Aminotransferease (SGPT /ALT) ≤ 2.5× ULN (Part 3 allowed ≤5×ULN in patients with liver metastases); c) Serum Glutamic-oxaloacetic Transaminase/Aspartate Aminotransferase (SGOT /AST) ≤ 2.5× ULN (Part 3 allowed ≤5×ULN in patients with liver metastases); d) Creatinine clearance (Ccr) ≥60 ml/min.
• Patients with no functional disorders of major organs.
• Fertile males and females of childbearing potential must agree to use effective contraception (so do their partners, using hormonal or barrier contraception, or abstinence) during the study and within at least 12 weeks after the last dose. The blood or urine pregnancy test for female patients of childbearing potential prior to enrollment must be negative.
⁃ Part 3: breast cancer patients who had received ≤4 previous chemotherapy regimens (adjuvant chemotherapy/neoadjuvant chemotherapy was considered as one chemotherapy regimen);
⁃ Part 3: history of prior treatment with at least one anthracycline or one taxane as neoadjuvant/adjuvant or advance therapy or both.
