A Multi-center, Randomized, Open, Parallel-group, Positive Drug-controlled Phase III Clinical Trial for Evaluating the Efficacy and Safety of Paclitaxel Polymeric Micelles for Injection Plus Gemcitabine and Paclitaxel for Injection (Albumin-bound) Plus Gemcitabine for Injection in the First-line Treatment of Metastatic Pancreatic Cancer
This trial is a multi-center, randomized, open, parallel-group and positive-controlled phase III trial to evaluate the efficacy and safety of paclitaxel polymeric micelles for injection plus gemcitabine as first-line treatment of metastatic pancreatic cancer compared with nab-Paclitaxel plus gemcitabine.
• 1\) Men or women aged 18 to 75 years old (including the critical value).
• 2）Metastatic pancreatic cancer confirmed by histology or cytology.
• 3）Patients who have not previously received any systemic therapy (including chemotherapy, targeted, and immunotherapy), radiotherapy, surgery, or investigational drugs for the treatment of metastatic pancreatic cancer; Patients who have previously received neoadjuvant or adjuvant chemotherapy could be enrolled if the interval between last treatment and recurrence and metastasis is more than 6 months.
• 4）Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
• 5）Survival is expected to be at least 3 months.
• 6）At least one metastatic lesion (non-lymph node lesions with a major diameter of ≥ 10 mm on CT or MRI and lymph node lesions with a minor diameter of ≥ 15 mm) that is measurable according to the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) and is amenable to accurate repeated measurement.
• 7）The major organs function well: a) white blood cell count ≥ 3.0 × 10\^9/L. b) Hemoglobin ≥ 90.0 g/L. c) Absolute neutrophil count ≥1.5 × 10\^9/L. d) Platelet count ≥100 × 10\^9/L. e) Total bilirubin ≤1.5 × upper limit of normal range (ULN). f) Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) ≤ 2.5 × ULN; For patients with liver metastasis, ALT, AST and ALP ≤ 5 × ULN; ALP ≤ 10 × ULN in patients with bone metastases.
• g) Serum creatinine (Cr) ≤ 1.5 × ULN or creatinine clearance estimated by Cockcroft Gault formula ≥50 ml/min.
• h) International normalized ratio (INR) ≤ 1.5 × ULN and prothrombin time (PT) or activated partial thromboplastin time (APTT) ≤ 1.5 × ULN.
• 8）Women of childbearing age are required to have a negative pregnancy test at the screening period and to use a highly effective contraceptive method for 6 months from the screening period to the last dose. Male participants whose partners are women of childbearing age are required to use a highly effective contraceptive method for 6 months after the first dose of a trial product until the last dose.
• 9）Patients are able to understand the steps of this trial, are willing to follow the clinical trial protocol to complete the trial, and sign the Informed Consent Form.
