Filter by:1. Establish a predictive model for the efficacy of immune checkpoint inhibitors (ICI) in Chinese patients with biliary tract cancers. By analyzing the dynamic changes of circulating tumor DNA (ctDNA) and other clinical and pathological features before and after ICI treatment in a cohort of patients with biliary tract tumors, a predictive model can be established to evaluate the efficacy of ICI treatment in the early stages or even before treatment, serving as a reliable tool for selecting patients who are likely to benefit from ICI treatment. 2. Investigate the clinical features of populations that benefit from different immune combination therapies. By comparing the differences and enrichment of mutations between patients receiving different treatment regimens, and if patients have sufficient pre-treatment tissue, further comparisons of differentially expressed genes and pathways may be made.
This is a Phase IIIb, open-label, single arm, multicentre study to assess the safety and efficacy of durvalumab in combination with investigator's choice of 3 different gemcitabine-based chemotherapy regimens in participants with aBTC with a WHO/ECOG PS of 0 to 2 at enrolment.
This is a single-arm, phase II clinical trial to evaluate the efficacy of XmAb20717 in patients with advanced biliary tract cancers who have progressed on, or were intolerant of, a gemcitabine-based chemotherapy regimen.
This is an interventional, prospective multicenter, open-label, phase II study in patients after curative surgery for BTC in a classic adjuvant situation, consisting of a two arm feasibility pilot part with a randomized pick-the-winner design and an option to proceed into a randomized phase 2/3 trial in order to compare the winner with the current SOC (capecitabine).
The aim of this study is to assess the R0 resection rate of tislelizumab combined with Lenvatinib and Gemox chemotherapy in the conversion therapy of potentially resectable locally advanced BTC.
Study design: Prospective, single-arm, single-center phase II clinical study; Primary endpoint: Conversion rate; Secondary endpoints: Safety, disease control rate, disease-free survival, and overall survival; Main characteristics of enrolled patients: Patients with initially unresectable biliary tract cancer; Interventions: Combination of Gemcitabine, Oxaliplatin, Sintilimab and Bevacizumab; Sample size: 34 patients; Treatment until: 1. successfully conversed to resectable disease 2. progressed disease 3. intolerable toxicity 4. patient requests withdrawal; Research process: In this study, patients who met the inclusion criteria were evaluated at the end of every 3 weeks of treatment, up to surgical treatment or disease progression; Safety evaluation: Evaluate adverse reactions according to CTCAE 4.0; Follow up: 12 months after the last case was enrolled.
The four tumour streams that will be studied in this protocol are based on immunotherapy sensitive rare cancers from CA209-538 which will be further investigated under this protocol and divided into four groups: 1. Neuroendocrine cancers: Atypical bronchial carcinoid, neuroendocrine carcinoma and Grade 3 NETs independent of primary site (SCLC excluded) 2. Biliary tract cancers: Intrahepatic cholangiocarcinoma and gallbladder carcinoma 3. Gynaecological malignancies: Ovarian clear cell carcinoma, uterine clear cell carcinoma, uterine/ovarian carcinosarcoma, uterine leiomyosarcoma and vaginal/vulva squamous cell carcinoma 4. Mismatch repair protein deficient (MSI-H) cancers (excluding colorectal carcinoma). The role of immunotherapy is being defined in more common cancer types, however because of their rarity, the efficacy of immunotherapy for these cancers is poorly defined. This protocol provides an important opportunity to establish whether the combination of nivolumab & ipilimumab has efficacy in these cancers.
This phase II trial investigates the effect of combining two immune therapies, atezolizumab and CDX-1127 (varlilumab), with or without cobimetinib, in treating patients with biliary tract cancer that cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Varlilumab is an immune agonist antibody that may further strengthen the immune system's attack on the cancer. Cobimetinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving atezolizumab in combination with varlilumab and cobimetinib may work better than atezolizumab and varlilumab alone in treating patients with unresectable biliary tract cancer.
This is open-label, phase II study enrolling advanced BTC patients who have failed to 1st-line chemotherapy.
Phase 1, first-in-human, open label study of CAR macrophages in HER2 overexpressing solid tumors.
