What is a clinical trial?

Although there are many definitions of clinical trials, they are generally considered to be biomedical or health-related research studies in human beings that follow a pre-defined protocol. We have both interventional & observational types of studies. Interventional studies are those in which the research subjects are assigned by the investigator to a treatment or other intervention, and their outcomes are measured. Observational studies are those in which individuals are observed and their outcomes are measured by the investigators.

March 2015 -
The goal of this clinical research study is to find the highest tolerated dose of the combination of nilotinib and MEK-162 that can be given to patients with CML or acute leukemia. Researchers also want to learn if the drug combination can help to control the disease. The safety of the drug combination will also be studied.
Sponsor: M.D. Anderson Cancer Center
Study type: Interventional
March 2015 - August 2015
This is a single center study to assess the efficacy of CyPath™ Early Detection Lung Cancer Assay to detect lung cancer cells from deep lung sputum.
Sponsor: bioAffinity
Study type: Interventional
March 2015 - December 2019
Drug bioavailability and disposition vary according to body weight and weight loss after bariatric surgery. This study evaluates the impact of body weight and weight loss on the pharmacokinetics of various probe drugs, and compares these effects in three groups of patients receiving either a gall bladder operation, gastric bypass or a very low calorie diet.
Sponsor: The Hospital of Vestfold
Study type: Interventional

The purpose of this study is to isolate and analyze exosomes, which are tiny carriers of important proteins and nucleic acids that serve as messenger systems in the blood and tissue. Blood and tissue from patients with pancreatic cancer will be compared with blood and tissue from patients with noncancerous pancreatic disease. Including patients without cancer will allow the investigators to establish "normal" values, which currently do not exist. The investigators will then look to see whether exosome activity has a connection to disease recurrence and outcomes in patients. The results of this study will be the basis for future studies exploring this area.

The current available antiretroviral (ARV) agents make possible a successful treatment of virtually all HIV-infected patients, even those heavily experienced subjects, with a history of previous failure to ARV drugs of different classes. However, some problems are still present, especially for specific populations, like pregnant women and infants. For these groups, most of currently available drugs are not used, because the lack of information on safety, efficacy, and pharmacokinetic/dynamic behavior of ARVs drugs. The mother to child transmission (MTCT) is still a problem in certain areas of the world, especially in resource-limited settings. In some settings, women often present to their first antenatal care visit late in the pregnancy, posing an additional problem: how to effectively treat these patients to assure they will have an undetectable viral load at the moment of delivering? Depending on the plasma viremia magnitude, and viral susceptibility it can take 6 or more weeks to reduce the viral load to less than the desired 1,000 copies of HIV-1 RNA / ml of plasma. To achieve this goal, it would be necessary the use of a potent, very efficacious ARV regimen that could provide such viral decay in a very short period. Raltegravir (RAL), the first HIV-1 integrase inhibitor, is a potent and safe ARV drug. The available evidence suggest it has no genotoxic potential, and promotes a rapid decline in HIV-1 plasma viremia. In addition, RAL is highly active against viral strains presenting different degree of resistance to other ARV drugs. Thus, RAL could be an ideal candidate to be used for prevention of MTCT for women with detectable viral load, presenting late in the course of pregnancy. Another attractive point is to consider that, due to the similarity between the integrase enzyme of HIV-1 and HTLV; RAL could be active against HTLV-1, blocking its replication. If our hypothesis is correct, the use f RAL-containing ARV regimens would reduce the MTCT of both agents. This study has the objective of evaluating the efficacy of RAL containing ARV regimens in reducing the HIV-1 RNA plasma viral load below 50 copies/ml, at the end of pregnancy, for late-presenters pregnant women and to compare the frequency of adverse events for women using RAL-based ARV regimens and comparators, and for their babies.
