Actual date on which the first participant was enrolled.

This trial has been designed as an open label, single center combination phase I trial. The primary objective is to determine the maximum tolerated dose (MTD) for chloroquine (CQ) in combination with concurrent radiotherapy with daily temozolomide in patients with a newly diagnosed GBM. Eligible patients will receive radiotherapy and chemotherapy according to standard protocol for newly diagnosed GBM. This consists of 33 daily fractions of 1.8 Gy to the tumor and surrounding margin in combination with TMZ 75 mg/m² per os daily (po qd) and six adjuvant cycles of TMZ 150 - 200 mg/m² po qd. Treatment will be combined with daily intake of escalating doses of chloroquine. Chloroquine will start with week before the start of radiotherapy and end on the last day of radiotherapy. The rate of subject entry and escalation to the next dose level will depend upon assessment of the safety profile of patients entered at the previous dose level. Toxicity will be evaluated according to the NCI common Terminology Criteria for Adverse Events (CTCAE), Version 4.0. The 3 + 3 cohort method is used. A minimum of three patients will be entered at each dose level. All three will be followed during the concomitant radiotherapy and a 4 week observation period before escalation to the next dose level. The start dose is 200mg chloroquine daily. Before opening the next higher dose level all toxic effects at the preceding dose level will be reviewed and expansion or escalation will be undertaken as appropriate

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

13 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.



Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

Inclusion Criteria: * Histologically confirmed grade IV supratentorial astrocytoma (glioblastoma multiforme) * Tumor tissue available for histopathological analysis (MGMT, EGFRvIII) * Diagnosis must have been made by biopsy or resection ≤ 3 months prior to study entry * 18 years or older * Karnofsky performance status ≥ 70 * Absolute neutrophil count at least 1.5 x 109/L and platelets at least 100 x109/L * Adequate renal function * Adequate hepatic function * absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule. * Females must have negative results for pregnancy tests performed * No breast feeding. * If male, subject must be surgically sterile or practicing a method of contraception Exclusion Criteria: * Prior radiotherapy * Prior chemotherapy * Recent (\< 3 months) severe cardiac disease (NYHA class \>1) (congestive heart failure, infarction) * History of cardiac arrythmia (multifocal premature ventricular contractions, uncontrolled atrial fibrillation, bigeminy, trigeminy, ventricular tachycardia) which is symptomatic and requiring treatment (CTC AE 4.0), or asymptomatic sustained ventricular tachycardia. Asymptomatic atrial fibrillation controlled on medication is allowed. * Cardiac conduction disturbances or medication potentially causing them * Treatment with investigational drugs in 4 weeks prior to or during this study * If the subject has clinically significant and uncontrolled major medical condition(s) including but not limited to: * uncontrolled nausea/vomiting/diarrhea: * active uncontrolled infection, including HIV and hepatitis (HBV, HCV) * psychiatric illness/social situation that would limit compliance with study requirements * any medical condition, with the opinion of the study investigator, places the subject at an unacceptably high risk for toxicities. * The subject has had another active malignancy within the past 3 years except for any cancer in situ that the principal Investigator considers to be cured. * Chronic systemic immune therapy (with the exception of corticosteroids) * Concurrent cytochrome P450 enzyme-inducing anticonvulsant drugs (e.g., phenytoin, carbamazepine, phenobarbital, primidone, or oxcarbazepine) * Known glucose-6-phosphate dehydrogenase deficiency * Psoriasis or porphyria * Known hypersensitivity to 4-aminoquinoline compound * Retinal or visual field changes unrelated to the tumor location prior to 4-aminoquinoline compound use

Group I

Experimental
Eligible patients will receive radiotherapy and chemotherapy according to standard protocol for newly diagnosed GBM. Chloroquine will be escalated in 3 dose-levels (200mg, 400mg and 600mg) up each containing a minimum of 3 and a maximum of 6 patients. Based on the results of the DSMB, an additional level of 300mg was added.
