Study Overview

Adebrelimab and Chidamide for Pancreatic Cancer

Pancreatic cancer is a kind of digestive system tumor with high malignant degree and poor prognosis. Most patients with pancreatic cancer are locally advanced or have distant metastases at the time of diagnosis, so it is extremely important to find effective drugs to control tumor metastasis. The primary treatment regimen for advanced pancreatic cancer remains chemotherapy, which results in a median survival time of only 8 to 12 months. Therefore, there is an urgent need to explore new combination therapies to extend survival. Therefore, this study aims to evaluate the efficacy and safety of Adebrelimab and Chidamide in Combination with Gemcitabine and S1 as first-line treatment for locally advanced or metastatic pancreatic cancer.

Pancreatic cancer is a kind of digestive system tumor with high malignant degree and poor prognosis. Most patients with pancreatic cancer are locally advanced or have distant metastases at the time of diagnosis, so it is extremely important to find effective drugs to control tumor metastasis. There are few approved first-line treatment options for metastatic pancreatic cancer. The FOLFIRINOX regimen (Irinotecan combined with Oxaliplatin and 5FU/LV) is recommended as a first-line treatment for patients with good overall performance status (ECOG 0-1), with a median overall survival of approximately 11.1 months. For patients with ECOG 0-2, the combination of Gemcitabine and Albumin-bound Paclitaxel is an option for first-line chemotherapy, with a median survival of 8.5 months. Single-agent Gemcitabine or S-1 is the standard first-line treatment for patients with poor overall performance status, resulting in a median survival of approximately 6 to 9 months. Therefore, for pancreatic cancer patients, the efficacy of existing first-line treatment regimens has reached a bottleneck, highlighting the urgent need to explore new first-line combination therapy options. Immunotherapy has demonstrated significant advantages in solid tumors, however, its application in pancreatic ductal adenocarcinoma (PDAC) has been disappointing to date. Although several promising preclinical studies have been conducted, translating these findings into clinical research remains challenging, likely due to the complex immunosuppressive tumor microenvironment of PDAC. Therefore, this study aims to evaluate the efficacy and safety of Adebrelimab and Chidamide in Combination with Gemcitabine and S1 as first-line treatment for locally advanced or metastatic pancreatic cancer.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

    Inclusion Criteria:
    1. 18 to 75 years old; 2. Histologically or cytologically confirmed pancreatic cancer (originating from the ductal epithelium of the pancreas) with clinically documented unresectable locally advanced or metastatic pancreatic cancer (stage III/IV according to the TNM stage of AJCC 8 pancreatic cancer); 3. have not previously received systematic antitumor therapy for the current stage of disease, including surgery (except stent placement), radiotherapy, chemotherapy, targeting, immunotherapy or investigational therapy; 4. There must be at least one measurable lesion as a target lesion (according to RECIST v1.1 standards); 5. ECOG(American Eastern Cancer Collaboration) Physical status score: 0~1; 6. Expected survival ≥3 months; 7. The function of major organs is good (no blood components, cell growth factors, whitening drugs, platelet drugs, anemia correction drugs are allowed within 14 days before enrollment); 8. Women of childbearing age must have had a blood pregnancy test within 7 days prior to enrollment, with a negative result, and be willing to use an appropriate method of contraception during the trial period and for 6 months after the end of treatment. For men, they should be surgically sterilized or agree to use an appropriate method of contraception during the study period and for 3 months after the end of treatment; 9. Voluntarily participate in the study and sign the informed consent; 10. Good compliance, agreed to cooperate with the survival follow-up.
    Exclusion Criteria:
    1) Have received any of the following treatments:
    1. Previous treatment with ICIs or HDACi; 2. Received the last anti-cancer treatment (including surgery, radiotherapy, etc.) within 4 weeks before enrollment; 3. Received any other investigational drug/device treatment within 4 weeks prior to enrollment; 4. Enrolling in another clinical study at the same time, unless it is an observational (non-interventional) clinical study or an interventional clinical study follow-up; 2) Patients known to be allergic to the components of the investigational drug; 3) Patients with known central nervous system metastasis; 4) Severe gastrointestinal dysfunction (bleeding, severe inflammation, obstruction, or diarrhea greater than grade 2); 5) Serious infections (CTC AE> Grade 2) occurred within 4 weeks prior to enrollment, such as severe pneumonia requiring hospitalization, bacteremia, infection complications, etc., and symptoms and signs of infection within 2 weeks prior to enrollment requiring intravenous antibiotic treatment (except for prophylactic antibiotic use); 6) Occurrence of arterial/venous thrombosis events, such as cerebrovascular accident, deep vein thrombosis and pulmonary embolism, within 1 year before enrollment; 7) Have clinical symptoms or heart diseases that are not well controlled, such as: (1)NYHA2 or above heart failure; (2) Unstable angina pectoris; (3) Myocardial infarction occurred within 1 year; (4) Patients with clinically significant supraventricular or ventricular arrhythmias requiring treatment or intervention.
