Efficacy Evaluation of Sequential Treatment With AG and Modified Folfirinox in Metastatic Pancreatic Adenocarcinoma

• Status: Recruiting
• Trial end date: 2024-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The prognosis of pancreatic cancer is extremely poor. Current guidelines recommend Nab-paclitaxel, Gemcitabine and modified Folfirinox as the first-line chemotherapeutic regimen. Studies have shown that sequential chemotherapeutic regimen can effectively delay the drug resistance and improve the effect of chemotherapy. Here investigators intend to assess the effect of sequential treatment with Nab-paclitaxel plus Gemcitabine and modified Folfirinox on metastatic pancreatic adenocarcinoma.

• Phase: Phase 1/Phase 2

Criteria

Inclusion Criteria:

1. Histologically or cytologically diagnosed metastatic pancreatic adenocarcinoma (excluding islet cell tumor) that can be measured according to RECIST criteria.

2. Without Radiotherapy, surgery, chemotherapy or experimental treatment for metastatic pancreatic cancer. Previous use of 5-FU or gemcitabine as a radiosensitizer in adjuvant therapy is allowed, but it should be taken at least 6 months ago and no residual toxicity. Patients receiving cytotoxic doses of gemcitabine or any other chemotherapy in adjuvant therapy are not eligible for this study.

3. ECOG score 0-1 points.

4. The first diagnosis time of metastatic pancreatic cancer should be within 6 weeks of the initial of treatment. Note: This interval is calculated from the date of final assessment of the confirmed pancreatic cancer metastasis.

5. No jaundice symptoms before treatment. Pain should be stable, and no need to adjust analgesic treatment. Patients with obvious or symptomatic ascites should be drained before treatment.

6. With enough blood cell counts during the screening period(less than 14 days before the treatment): 1) The absolute count of neutrophils(ANC) is more than 1.5 ×10^9/L; 2) Platelet count was greater than 100,000/mm^3 (100 x10^9/L); 3).

Hemoglobin (Hgb) is more than 9 g/dL.

7. With normal blood biochemical parameters during the screening period(less than 14 days before the treatment): 1). AST (SGOT), ALT (SGPT) <2.5*ULN, if there is obvious liver metastasis, it is allowed to <5*ULN. 2). Total bilirubin is less than ULN. 3). Serum creatinine is within the normal limit, or the serum creatinine level is higher or lower than the normal value of the body, but the calculated clearance rate is more than 60 mL/min/1.73 m^2. If creatinine clearance is used, the actual body weight should be used to calculate creatinine clearance (for example, the Cockroft-Gault formula). Patients with body mass index (BMI) >30 kg/m^2 should use fat free body weight.

8. Acceptable coagulation test results (less than 14 days before treatment): prothrombin time (PT) and partial thromboplastin time (PPT) were within the normal limit (+15%).

9. With no clinically significant abnormal urine analysis (less than 14 days before treatment).

10. Male or non pregnant and non lactating women aged 18 or above who signed the informed consent.

11. Patients were informed of the nature of the study and agreed to participate in the study, and informed consent was signed before participating in any research-related activities.

Exclusion Criteria:

1. With brain metastases.

2. Only locally progressive diseases.

3. Serum albumin level decreased by more than 20% within 72 hours of first days before screening visit to first cycle.

4. With a history of malignancies (including chronic leukemia) over the past 5 years. Patients with previous history of carcinoma in situ or basal cell or squamous cell carcinoma can be included. Patients with other malignancies who have been cured by surgery or surgery plus radiotherapy alone and remain disease-free for at least five years are also eligible.

5. Suffering from active or uncontrollable bacterial, viral or fungal infections requiring systemic treatment.

6. Known HIV infection, and/or active hepatitis B virus or hepatitis C virus infection (for patients with history of HBV or HCV infection, should be discussed with researchers).

7. Major surgeries were performed within 4 weeks of the first day of treatment in this study (i.e. non-removal of organs for diagnostic biopsy).

8. Myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass grafting, New York Heart Association (NYHA) grade III-IV heart failure, uncontrolled hypertension, clinically significant arrhythmias or electrocardiographic (ECG) abnormalities, cerebrovascular accidents, transient ischemic attacks, epileptic seizures or clinically significant arrhythmia or abnormal electrocardiogram (ECG) history within 6 months before treatment.

9. With history of allergy or hypersensitivity of any research drug or its adjunct.The patient presents the events outlined in the "Contraindications or Special Warnings and Cautions" section of the product or control drug prescription information.

10. With history of connective tissue diseases (such as lupus, scleroderma, nodular arteritis).

11. With history of interstitial pneumonia, slow progressive dyspnea, dry cough, sarcoidosis, silicosis, idiopathic pulmonary fibrosis, allergic pneumonia, or multiple allergies.

12. Any condition that may impair patient safety or integrity of research data, including serious medical risk factors, medical events, laboratory abnormalities, or mental illness.

13. Patients entering any other clinical study, testing for an intervention drug, or may interfere with the evaluation of this study procedure.

14. Patients are unwilling or unable to follow the research procedure or plan to take 7 or more consecutive days off during the study period.
