Dopamine Agonist Treatment of Non-functioning Pituitary Adenomas
Study Purpose
Due to lack of hormone overproduction in non-functioning pituitary adenomas (NFPAs), only the symptomatic adenomas or large adenomas with proven growth and risk for symptoms in near future will undergo pituitary surgery. The remaining adenomas are monitored regularly. Operation of these large adenomas will rarely remove all tumour tissue, and there is also a risk of worsening of pituitary function. Often, adenomas with the highest growth potential are operated several times and some also need radiation therapy, providing additional risk for pituitary failure. Unlike some of the hormone-producing adenomas, there is no established pharmacological treatment for NFPAs. However, there are a few non-randomized studies suggesting that treatment with dopamine agonists may slow growth, and also induce tumour shrinkage. At present, cabergoline is the dopamine agonist most widely used in the treatment of pituitary adenomas secreting prolactin. Aim is to study the effect of medical treatment with cabergoline in non-functioning pituitary adenomas on the change in tumour volume.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial Details
Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT02288962 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
