Von Hippel-Lindaus Disease clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Assessment of Residual VHL Function in Tumors - Can it Predict the Patients' Individual Course of Disease?

Start date: September 2014
Phase: N/A
Study type: Observational

The investigators aim to analyze tumors from vHL patients who have different courses of disease and different types of VHL gene alterations to characterize which types of genetic alterations the tumors contain and how these alterations affect the tumor cells' behavior on a molecular level. The investigators will then compare these observations to vHL disease outcome in patients and families. It is already known that most vHL tumors develop when both copies of the VHL gene in a cell are inactivated. The first copy is inactivated in all the person's cells from birth ("first hit"), leaving just one functional copy. A tumor can develop from cells where the second copy is also inactivated ("second hit"). So far, only the molecular consequences of the first hit have been investigated. It is our hypothesis that both the first and second hits in combination have consequences for tumor development and clinical outcome. The investigators will include tumors from patients with different disease courses and different types of "first hits" and analyse the tumors' DNA in order to find correlations between the first and second hits and patients' and families' medical histories. The investigators hereby hope to give new insights into how vHL tumors grow and which genetic factors influence tumor development. These results will contribute to the current knowledge of vHL and help us get one step closer to be able to predict an individual's tumor risks and need for surveillance.
