5 Clinical Trials for Various Conditions
The optimal approach to the drainage of malignant obstruction at the biliary hilum remains uncertain. This is a randomized comparative effectiveness study of percutaneous transhepatic biliary drainage (PTBD) vs. endoscopic retrograde cholangiography (ERC) as the first intervention in patients with cholestasis due to suspected malignant hilar obstruction.
The purpose of this study is to test the safety of giving external beam radiation, followed by a Cyberknife radiosurgery boost at different dose levels, together with a chemotherapy drug called capecitabine. The dose of Cyberknife radiosurgery boost will be made higher slowly in this protocol. Patients with hilar cholangiocarcinoma (Klatskin tumor), which is not amenable for surgical removal, are eligible. The hypothesis is that highly focused high dose radiation delivered using Cyberknife in conjunction with traditional radiation and chemotherapy can improve outcome in this patient population.
A global study to assess the efficacy and tolerability of rilvegostomig compared to placebo in combination with investigator's choice of chemotherapy in participants with BTC after surgical resection with curative intent.
Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction. This research study will evaluate the efficacy and safety of PDT with porfimer sodium administered with Standard Medical Care (SMC) compared to SMC alone on the overall survival time of patients with non-operable advanced cholangiocarcinoma, a rare cancer of the bile ducts. It will involve 200 patients across North America and Europe. Other countries may participate if needed. Participation will last at least 18 months.
This study will assess the safety and effectiveness of fimaporfin-induced photochemical internalisation (PCI) of gemcitabine complemented by systemic gemcitabine/cisplatin chemotherapy compared to gemcitabine/cisplatin alone, in patients with inoperable cholangiocarcinoma (CCA). Participants will be randomly assigned to one of the treatment groups and will receive study treatment for 6 months, followed by assessments every 3 months, as applicable.
