چکیده
Abstract The poor prognosis of patients affected by glioblastoma (GBM) prompts the search for new and more effective therapies, particularly GBMs with unmethylated MGMT. In this regard, drug repurposing, can represent a safe inexpensive way to bring novel pharmacological approaches from bench bedside. Chlorpromazine, medication in use since six decades therapy psychiatric disorders, shows vitro features that make it eligible repositioning GBM therapy. our experimentation on cell lines, chlorpromazine inhibited viability an apoptosis-independent way, induced polyploidy, reduced cloning efficiency as well neurosphere formation downregulated expression stemness genes. Notably, we found synergized temozolomide, reducing strongly cooperated inducing death all lines assayed. With these assumptions, started multicentric Phase II clinical trial newly diagnosed MGMT adding temozolomide adjuvant phase standard first-line therapeutic protocol. experimental procedure involves combination CPZ treatment TMZ Stupp is administered orally at dose 50 mg/day – GG 1-28 every cycle TMZ. At present, 53 out 60 planned have been enrolled, without relevant toxicity.

Phase II trial of irinotecan and metronomic temozolomide in patients with recurrent glioblastoma.
This phase II study was conducted to determine the efficacy and safety of metronomic temozolomide (TMZ) in combination with irinotecan in glioblastoma (GB) at first relapse. Patients with GB at first relapse received TMZ 50 mg/m/2day divided into three doses, except for a single 100 mg/m2 dose, administered between 3 and 6 h before every irinotecan infusion. Irinotecan was given intravenously a...

Multicenter phase II trial of temozolomide in patients with glioblastoma multiforme at first relapse.
BACKGROUND Recurrent glioblastoma multiforme (GBM) is resistant to most therapeutic endeavors, with low response rates and survival rarely exceeding six months. There are no clearly established chemotherapeutic regimens and the aim of treatment is palliation with improvement in the quality of life. PATIENTS AND METHODS We report an open-label, uncontrolled, multicenter phase II trial of temoz...
