Trial Information

Medical Treatment of "High-Risk" Neurofibromas in Patients With Type 1 Neurofibromatosis: A Clinical Trial of Sequential Medical Therapies

The study's design involves treating eligible patients with a combination of celecoxib and
pegylated interferon alpha-2b. If the patients have at least a partial response after six
months, they may continue on the same treatment for up to two years. If the patient
experiences less than a partial response, or has progressive disease after six months of
therapy, then vincristine and temozolomide will be added to the celecoxib and interferon
alpha-2b backbone. Response to treatment will be assessed after a minimum of six months,
presuming the patient has not experienced progressive disease. Total duration of therapy on
study is two years for any individual treatment plan.
