5 Clinical Trials for Various Conditions
The main aim of this study is to understand how moderate and severe liver impairment (based on the Child-Pugh classification) affects the body's processing of a single dose of 10 mg maximum of palovarotene, compared to healthy participants with normal liver function. The study will also assess the safety and tolerability of the single dose of palovarotene. Participants will be enrolled in stages and divided into three groups based on their liver function: * Group 1: Healthy participants with normal liver function * Group 2: Participants with moderate liver impairment * Group 3: Participants with severe liver impairment (only enrolled if Group 2 results are safe and acceptable) Blood samples will be taken to assess how the drug binds to proteins in the blood. Participants will undergo various safety checks and procedures. Participants will stay in the clinical unit until Day 5 for these assessments and will return on Day 10 for a final visit.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of docetaxel in treating patients with advanced solid tumors that have not responded to standard therapy or for which there is no effective therapy.
Chronic liver disorders (CLD) are a major cause of morbidity and mortality for individuals in the US. Though serologic analysis will often lead to a conclusive diagnosis, liver biopsy remains an important method for helping to determine the etiology and stage of LD. Percutaneous liver biopsy (PLB), transjugular liver biopsy (TLB) and surgical liver biopsy (SLB) are alternative methods for obtaining hepatic tissue. In recent years endoscopic ultrasound guided-liver biopsy (EUS-LB) has come to the forefront as a safe and effective method for obtaining tissue in CLD. There are several studies of the safety of EUS-LB as well as the adequacy of specimens obtained in this fashion. Most studies involve a 19-g needle, therefore in this study we hope to compare the tissue yields of a 19-g fine needle biopsy (FNB) needle, in comparison to conventional 19-g fine needle aspiration (FNA) needle. We predict that 19-g FNA and 19-g FNB needle will demonstrate similar diagnostic accuracy, with less visible blood artifact. Similarly, we predict the safety to be equal.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Irinotecan may be effective in treating patients with abnormal liver or kidney function or who have received radiation therapy. PURPOSE: Phase I trial to study the effectiveness of irinotecan in treating patients with solid tumors or lymphoma who have abnormal liver or kidney function or who have had previous radiation therapy to the pelvis.
Liver transplantation is a high risk, high-cost intervention that extends life in over 8,000 patients in the US each year. Of those that receive transplants, 1 in 3 will have a complication related to their heart after transplant. Research has been done to attempt to reduce the risk of these complications from occurring. High blood pressure, otherwise known as "hypertension," is an important risk factor for heart complications. Hypertension is found in 92% of liver transplant recipients within 6 years of their procedure. However, using data from our transplant patients at Northwestern we recently showed that having a normal blood pressure in the first year following liver transplant lowered the risk of heart complications and the risk of death by over half. However, there are no studies investigating the best medications to lower blood pressure in liver transplant recipients. There are several types of medications that can be used to treat high blood pressure. Currently, most transplant providers use a class of medications called calcium channel blockers as the first medications for hypertension in liver transplant patients. However, there is little data to support this recommendation. There is some new evidence suggesting that another class of medications, called thiazide-like diuretics, might be beneficial to lower blood pressure in liver transplant recipients. The current study will use two different medications: the calcium channel blocker called amlodipine besylate (at dose of 10mg) and the thiazide-like diuretic known as chlorthalidone (25mg). Both medications are taken once per day by mouth and are FDA approved for the treatment of high blood pressure in the general population. The main purpose of this study is to determine how well these two medications lower blood pressure and how they may improve markers of heart function and kidney function in liver transplant recipients. The long-term goal of this research is to improve heart outcomes in those that have undergone liver transplant by addressing risk factors that can be modified, including blood pressure. This study will help determine the size of the needed group for further studies to ensure proper investigation of which of these two medications may most benefit liver transplant patients.
