What this study is
This study is designed as a single center, prospective, open label, single-arm therapeutic trial with both surgical and non-surgical cohorts.
What's being tested
- Lomustine
Intervention · DRUG
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 both cohorts, lomustine will be administered as 110 mg/m2 PO once every 6 weeks.
- Imipramine Hydrochloride
Intervention · DRUG
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 Cycle 1 Day 1. 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, if tolerated, to attain a maximum dose of 200mg/day in 16 days.
