STEMVAC in Patients With Early Stage Triple Negative Breast Cancer
Recruiting
This phase II trial studies the effect of DNA plasmid based vaccine (STEMVAC) in treating patients with patients with stage IB-III triple negative breast cancer. STEMVAC may wake up the immune system in patients who have had a diagnosis of triple negative breast cancer and have been treated. STEMVAC targets proteins that are expressed on breast cancer cells and works by boosting the immune system to recognize and destroy the invader cancer cell proteins that are causing the disease. The purpose... Read More

HCRN Endoscopic Versus Shunt Treatment of Hydrocephalus in Infants
Recruiting
Hydrocephalus is a potentially debilitating neurological condition that primarily affects babies under a year of age and has traditionally been treated by inserting a shunt between the brain and the abdomen. A newer endoscopic procedure offers hope of shunt- free treatment that may reduce complications over a child's life, but it is not clear if the endoscopic procedure results in similar intellectual outcome as shunt. Therefore, the investigators propose a randomized trial to compare intellectu... Read More
