Investigator-Initiated Study of Imipramine Hydrochloride and Lomustine in Recurrent Glioblastoma

Официальное название

A Phase II, Investigator-Initiated Study of Imipramine Hydrochloride and Lomustine in Recurrent Glioblastoma

Обзор

This study is designed as a single center, prospective, open label, single-arm therapeutic trial with both surgical and non-surgical cohorts.

Вмешательства

• Препарат Lomustine
  For surgical cohort patients, lomustine will be initiated (C1D1) within 6 weeks of surgery as soon as patient is deemed by the investigator (or designee) to be recovered enough for chemotherapy. Initiation of lomustine must be initiated within 6 weeks. If patient cannot be safely initiated on lomustine within this timeframe then they will be replaced. For non-surgical cohort patients (the decision for surgery is made independent of study participation), lomustine will be initiated on C1D1. For
• Препарат Imipramine Hydrochloride
  For the surgical cohort, imipramine hydrochloride will be initiated within a minimum of 16 days to a maximum of 3 weeks prior to surgery. Imipramine hydrochloride will be administered as 50mg PO (oral) QHS (at bedtime) for 4 days followed by a dose increase (taper-up) of 50mg/day every fourth day to attain a maximum dose of 200mg/day in 16 days. For non-surgical cohort patients (the decision for surgery is made independent of study participation), imipramine hydrochloride will be initiated on C
