Clinical Trial Summary

Background:

• Von Hippel-Lindau (VHL) disease is a rare gene disease. People with VHL often have a brain tumor called hemangioblastoma. Standard treatment for these tumors is risky surgery. Researchers want to find new ways to treat people who have the tumors. They want to see if a drug that fights other cancers might slow the growth of hemangioblastomas in some people with VHL. Some people with VHL have mutations that make abnormal proteins. Tumors form in such people because the abnormal protein is broken down quickly. The cancer drug may work in these tumors by preventing breakdown of protein.

Objective:

• To study how the drug vorinostat affects hemangioblastomas in people with VHL.

Eligibility:

• Adults at least 18 old with hemangioblastomas from VHL.

Design:

• Participants must already be in study 03-N-0164. They must have tumor surgery scheduled.

• Participants must stop taking most medications 14 days before surgery.

• One week before surgery, participants will enter the hospital. They will be screened with medical history and physical and neurological exams. They will give blood and urine samples. Participants will have an electrocardiogram. For this test, small sticky patches are put on the arms, legs, and chest. Participants will lie still for a few minutes while a machine records heart rate and rhythm.

• Participants will take one vorinostat by mouth each day for 7 days.

• Participants will have blood drawn during the week to check for any side effects.

• Participants will have their tumor removed in surgery. Researchers will study the tumor tissue for the effects of the study drug.

• A nurse will call participants 1 month after surgery to check for side effects.

Description:

Background

Central Nervous System (CNS) hemangioblastomas are the most common tumor found in the familial neoplasia syndrome, Von Hippel-Lindau (VHL).

Hemangioblastomas cause significant morbidity and mortality. While surgical resection is the treatment of choice for CNS hemangioblastomas, it is associated with morbidity and death. There is a critical need for new non-invasive treatments of VHL-associated CNS hemangioblastomas.

Vorinostat is a histone deacetylase inhibitor (HDACi) that is FDA-approved for the treatment of refractory cutaneous T-cell lymphoma (CTCL). Vorinostat has been tested in other hematologic malignancies and solid tumors. Recent data suggests that vorinostat may have a potent therapeutic effect in the treatment of VHL-associated hemangioblastomas in patients with missense germline mutations of the VHL gene. In most VHL mutation types, the abnormal VHL protein content is not active, which leads to tumor formation and growth. In missense mutation VHL disease, tumor cells contain a malformed VHL protein that is partially active. However, the protein is degraded quickly by normal cellular mechanisms. Vorinostat prevents degradation of a malformed protein within the tumors. Increased protein leads to slower growth in these tumors.

Objective

To determine whether vorinostat reduces degradation of mutant VHL protein in VHL patients with germline missense mutations.

Eligibility

Adult patients (age greater than or equal to 18 years) with a known germline missense VHL gene mutation that require surgical resection of a hemangioblastoma.

Design

We intend to conduct a pilot study with vorinostat in six patients with hemangioblastomas causing significant symptoms from tumor growth. Vorinostat will be administered if the patients are deemed surgical candidates. Patients will receive one (1) dose of 400 mg of vorinostat daily for seven (7) days prior to surgery. On the day of surgery, the patients will not receive vorinostat. Patients will undergo surgery as usual, with no change in planning or technique of the procedure. The tumor specimens from surgery will be examined for presence and quantity of mutant VHL protein. Comparisons for levels of mutant VHL protein will be made with tissue banked from previous surgical resections under 03-N-0164. Measurements of genetic expression of vascular endothelial growth factor (VEGF) and erythropoietin (EPO) will also be performed on these specimens.

Outcome Measures

1. The presence and quantity of mutant VHL protein in resected hemangioblastoma specimens, including comparison of specimens without vorinostat treatment and those with presurgical vorinostat treatment.

2. Measurement of VEGF and EPO results from resected hemangioblastoma specimens, including comparison of specimens without vorinostat treatment and those with presurgical vorinostat treatment.

Eligibility

• INCLUSION CRITERIA
