PD-1 Combined With Chemotherapy and PULSAR in LAPC and Local Recurrence Patients

Recruiting now · Phase 2

Conditions studied: Pancreatic Cancer

In brief

This trial is a phase II clinical trial of the safety and efficacy of PD-1 antibody (Toripalimab) in combination with paclitaxel (albumin-bound type) and gemcitabine and PULSAR radiotherapy in patients with locally advanced unresectable pancreatic cancer and patients with only local recurrence after pancreatic cancer surgery, to observe the safety and efficacy of PD-1 antibody (Toripalimab) in combination with paclitaxel (albumin-bound type) and gemcitabine and PULSAR in the treatment of patients with locally advanced unresectable pancreatic cancer.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Sign the informed consent form. The subject has received a full explanation and understanding of the purpose, content, predicted efficacy, pharmacological effects, and risks of this trial, and the subject has signed an informed consent form;
• Target group
• Locally advanced pancreatic adenocarcinoma confirmed by histopathology or cytology, or pancreatic cancer with only local recurrence but no distant metastasis after surgery (local recurrence includes tumor bed recurrence and regional lymph node metastasis, which needs to be confirmed by biopsy pathology or PET -CT shows high metabolic activity, more than 6 months after the completion of postoperative adjuvant treatment);
• There is at least one measurable objective lesion according to RECIST1.1 standards;
• ECOG score 0-1 points;
• Expected survival time ≥ 3 months;
• Willing to comply with research procedures and able to undergo treatment (including surgery) and follow-up;
• There are no contraindications for the use of PD-1, PD-L1, gemcitabine and paclitaxel for injection (albumin-bound);
• There are no contraindications to radiotherapy;
• Abnormal physical examination and laboratory test results
• Hematological dysfunction is defined as i) absolute neutrophil (ANC) count ≥1.5×109/L; ii) platelet (PLT) count: ≥80×109/L; iii) hemoglobin (Hb) level ≥ 90g/L.
• Abnormal liver function is defined as: i) Total bilirubin (TBil) level: ≤ 1.5 times the upper limit of normal (ULN); ii) Aspartate aminotransferase (AST) and alanine; aminotransferase (ALT) levels ≤ 2.5 times the ULN, if liver metastasis is present, ≤5 times ULN;
• Abnormal renal function definition: serum creatinine ≤ 1.5 times ULN, or calculated creatinine clearance ≥ 50ml/min;
• Definition of abnormal coagulation function: international normalized ratio (INR) ≤ 1.5 times ULN, and prothrombin time (PT) or activated partial thromboplastin time (APTT) ≤ 1.5 times ULN, unless the subject is receiving anti- Coagulation treatment.
• Subjects who are positive for hepatitis B surface antigen (HBsAg) and whose peripheral blood hepatitis B virus deoxyribonucleic acid (HBV-DNA) titer is ≤1×103 copy number/L; if they are HBsAg-positive and whose peripheral blood HBV-DNA titer is detected ≥1×103 copy number/L, if the researcher believes that the subject's chronic hepatitis B is in a stable phase and will not increase the subject's risk, the subject is eligible for inclusion;
• Age and reproductive status
• Men and women aged 18-75;
• Subjects of childbearing age must agree to take adequate contraceptive measures during the trial; the serum or urine pregnancy test of women of childbearing age must be negative 24 hours before the start of chemotherapy;
• Women must be non-lactating.

You may not qualify if…

• Have received anti-PD-1 or anti-PD-L1 antibody treatment in the past;
• Have received any investigational drugs within 4 weeks before using the investigational drugs for the first time;
• Enroll in another clinical study at the same time, unless it is an observational (non-interventional) clinical study or an interventional clinical study follow-up;
• Have received radiotherapy for the upper abdomen in the past;
• Medical history and concurrent diseases
• Uncontrolled serious medical diseases that the researcher believes will affect the subject's ability to receive the treatment of the research plan, such as combined with serious medical diseases, including severe heart disease, cerebrovascular disease, uncontrolled diabetes, and uncontrolled hypertension, uncontrolled infection, active peptic ulcer, etc;
• Have active, known, or suspected autoimmune disease (including but not limited to uveitis, enteritis, hepatitis, hypophysitis, nephritis, vasculitis, hyperthyroidism, hypothyroidism, and need for bronchodilators treatment of asthma, etc.). Subjects with hypothyroidism requiring only hormone replacement therapy and skin diseases not requiring systemic treatment (such as vitiligo, psoriasis, or alopecia) were eligible;
• Have active tuberculosis infection. Patients with active pulmonary tuberculosis infection within 1 year before the medication will be excluded, even if they have been treated; patients with a history of active pulmonary tuberculosis infection more than one year ago will also be excluded unless it is proven that they have previously received standard anti-tuberculosis treatment;
• Previous interstitial lung disease or (non-infectious) pneumonia requiring oral or intravenous steroid therapy;
• Long-term systemic corticosteroids (dose equivalent to >10 mg prednisone/day) or any other form of immunosuppressive treatment are required. Subjects using inhaled or topical corticosteroids were eligible;
