Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ongoing treatment for malignancy by at the University of Chicago with any agent with recognized, specific inhibition of VEGF, VEGF-receptors, or downstream signaling molecules with the specific intention of inhibiting signaling of this pathway. These agents include but are not limited to: bevacizumab (Avastin™), sorafenib (Nexavar™), sunitinib (Sutent™), axitinib (AG-013736), and AZD 2171.
  • Treatment of hypertension with at least 2 or more anti-hypertensive medications with blood pressure remaining greater than 140/90 mmHg.
  • Stable management of other toxicities from the cancer treatments
  • Expected to continue current cancer treatments for at least 4 weeks
  • 18 years and older
  • Ability to understand and the willingness to sign a written informed consent document prior to any study specific procedures.

Exclusion Criteria:

  • Concurrent use of hematopoietic supportive treatment with erythropoietin or congeners.
  • Current uncontrolled toxicities due to the cancer treatments.
  • Patients having known contraindications to hydralazine or minoxidil therapy.
  • Any readings of systolic blood pressure >200 mmHg or diastolic blood pressure >120 mmHg in the four (4) weeks prior to screening.
  • Use of either minoxidil or hydralazine in the six (6) months prior to screening.
