Filter by:Immunotherapy of cancer based on PD-1/PD-L1 blockade has prompted a revolution in cancer clinical management, albeit as yet immunotherapy-based treatment approaches in pancreatic cancer and biliary tract cancer (BTC) remain to have proven value, highlights the urgency for designing novel therapeutic strategies to combat these deadly diseases. The immunomodulatory effect of lenvatinib (Lenvatinib is an oral multi-kinase inhibitor) on tumor microenvironments may contribute to antitumor activity of immune checkpoint blockade. This one-arm, phase I/II study is designed to assess the safety and efficacy of the combined regimen of Durvalumab (anti-PD-L1 antibody), Lenvatinib and Paclitaxel albumin (nab-paclitaxel).
The transparent cap-assisted endoscope has the function of fixing field of view and increasing visual space. It has been widely used in gastrointestinal examination and treatment. In this study, the investigators intend to apply transparent cap-assisted choledochoscopy to endoscopic biliary tract exploration and biopsy to investigate whether transparent cap-assisted choledochoscopy can improve operability, visual field clarity, and biopsy accuracy.
This phase I trial studies the side effects of pressurized intraperitoneal aerosolized chemotherapy (PIPAC) nab-paclitaxel in combination with gemcitabine and cisplatin in treating patients with biliary tract cancer that has spread to the peritoneum (peritoneal metastases). PIPAC involves the administration of intraperitoneal chemotherapy (anticancer drugs given directly to the lining of the abdomen). PIPAC uses a nebulizer (a device that turns liquids into a fine mist) which is connected to a high-pressure injector and inserted into the abdomen (part of the body that contains the digestive organs) during a laparoscopic procedure (a surgery using small incisions to introduce air and insert a camera and other instruments into the abdominal cavity for diagnosis and/or to perform routine surgical procedures). Pressurization of the liquid chemotherapy through the study device results in aerosolization (a fine mist or spray) of the chemotherapy intra-abdominally (into the abdomen), which results in the drug reaching more of the tissue as well as reaching deeper into the tissue, which reduces the amount of chemotherapy that needs to be used and potentially reduces side effect. Chemotherapy drugs, such as nab-paclitaxel, gemcitabine, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nab-paclitaxel via PIPAC in combination with standard of care gemcitabine and cisplatin may reduce side effects and make this chemotherapy regimen more tolerable in patients with biliary tract cancer that has spread to the spread to the peritoneum.
This is a prospective, open-label, single-center clinical study, to evaluate the efficacy and safety of Capecitabine combined with Lenvatinib and Tislelizumab as adjuvant treatment after resection in patients with biliary tract cancer.
This is a Phase Ib/II, multicenter, open-label study to evaluate the safety and preliminary efficacy of TT-00420 tablet, as monotherapy or in combination regimens, in patients with advanced solid tumors (solid tumor, BTC and TNBC).
Chromosomal instability (CIN) refers to ongoing chromosome segregation errors throughout consecutive cell divisions. CIN is a hallmark of human cancer, and it is associated with poor prognosis, metastasis, and therapeutic resistance. Analyzing CIN of the DNA extracted from bile tract exfoliated cells in bile samples seems a promising method for diagnosing, monitoring, and predicting the prognosis of patients with malignant biliary obstruction, including biliary tract cancer (BTC), pancreatic head carcinoma. CIN can be assessed using experimental techniques such as bulk DNA sequencing, fluorescence in situ hybridization (FISH), or conventional karyotyping. However, these techniques are either time-consuming or non-specific. The investigators here intend to study whether a new method named Ultrasensitive Chromosomal Aneuploidy Detection (UCAD), which is based on low-coverage whole-genome sequencing, can be used to analyze CIN thus helping diagnose malignant biliary obstruction and assessing follow-up.
First-line gemcitabine plus cisplatin chemotherapy is the standard first-line treatment for unresectable or metastatic advanced biliary tract cancer and the optimal duration of the treatment is not mentioned in current clinical guidelines. In the pivotal phase 3 ABC-02 trial, patients received up to 6 to 8 cycles of treatment and stopped without maintenance and our retrospective study shows no significant benefit of continuing gemcitabine plus cisplatin beyond 6 to 8 cycles. However, the survival outcomes of patients who completed 6 to 8 cycles of gemcitabine plus cisplatin without progression are dismal with progression-free survival from the last dose of the treatment of median 5.2 months in a prior retrospective study. Indeed, there is an unmet clinical need in terms of maintenance therapy for advanced biliary tract cancer without progression to first-line gemcitabine plus cisplatin chemotherapy. Durvalumab with/without tremelimumab, anti-CTLA4 inhibitor, showed encouraging results in recently presented study for treatment of advanced biliary tract cancer combination with gemcitabine plus cisplatin. Combination of olaparib and durvalumab showed promising results for metastatic HER-2 negative BRCA mutated breast cancer. For DDR gene mutated advanced biliary tract cancer, olaparib plus durvalumab combination may show synergistic effect with better efficacy than olaparib monotherapy. Both olaparib and durvalumab are relatively well tolerated compared to other cytotoxic chemotherapeutic agents. Olaparib may have some degree of myelosuppression, most patients are expected to well tolerate. Although combination of durvalumab and olaparib may cause additional adverse events, these also might be tolerable, considering that there are no overlapping toxicities between durvalumab and olaparib and the safety data for the combination of durvalumab with olaparib. Considering poor prognosis in patients with advanced biliary tract cancer and lack of maintenance treatment following scheduled first-line GemCis, clinical benefits with maintenance olaparib or olaparib plus durvalumab weigh more than the potential risks.
The primary objective of this study is to evaluate the ability to recruit and retain participants, and to successfully conduct a psilocybin-based protocol, for a study of the treatment of distress related to inoperable pancreatobilliary cancer. Secondary objectives include pre/post, and longitudinal measurement of distress in intervention participants and a paired family member who is in an observational arm.
No validated biomarkers exist that can identify patients with biliary tract cancer at an early stage or predict treatment outcomes. The objective of the present study is to find diagnostic, prognostic and predictive biomarkers.
