Brief Summary

Glioblastomas (GBM) are the most common type of primary brain tumors with an annual incidence of approximately 500 patients in the Netherlands. Despite extensive treatment including a resection, radiation therapy and chemotherapy, the median overall survival is only 14.6 months. Epidermal growth factor receptor (EGFR) amplification or mutation is regularly observed in GBM and is thought to be a major contributor to resistance to radiotherapy and chemotherapy. The most common EGFR mutation in GBM (EGFRvIII) is present in 30-50% of GBM. Previously MAASTRO lab has shown that expression of EGFRvIII provides GBM cells with a survival advantage when exposed to stress factors such as hypoxia and nutrient deprivation. These metabolic stress factors activate a lysosomal degradation pathway, known as autophagy. Inhibition of autophagy sensitizes cells to hypoxia, reduces the viable hypoxic fraction in tumors with \> 40% and subsequently sensitizes these tumors to irradiation. Chloroquine (CQ) is a potent autophagy blocker and is the most widely investigated substance in this context. Previously, the effect of CQ has been demonstrated in a small randomized controlled trial in GBM treated with radiotherapy and carmustine. Although not statistically significantly different, the rate of death over time was approximately half as large in patients receiving CQ as in patients receiving placebo. The intracellular effects of CQ are dose-dependent. Therefore, the authors suggest an increase in daily dose of CQ may be necessary. Furthermore, the combination of CQ with TMZ may induce more damage to the neoplastic cells. In the phase I part of this trial the recommended dose of CQ in combination with radiotherapy and temozolomide will be tested. In the phase II part of the trial patients with a histologically confirmed GBM will be randomized between standard treatment consisting of concurrent radiotherapy with temozolomide and adjuvant temozolomide (arm A) and standard treatment plus CQ (arm B).

Study Arms (2)

Standard

NO INTERVENTION

Radiotherapy and chemotherapy according to standard protocol for newly diagnosed GBM. This consists of 30 daily fractions of 2 Gray (Gy) or 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.

Experimental arm

EXPERIMENTAL

Radiotherapy and chemotherapy according to standard protocol for newly diagnosed GBM. This consists of 30 daily fractions of 2 Gray (Gy) or 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. In addition this treatment will be combined with a daily intake of the recommended phase two dose (RPTD) of chloroquine (CQ).

Drug: Chloroquine

Interventions

CQ will start with one week before the start of radiotherapy and end on the last day of radiotherapy.

Also known as: A-CQ

  • 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)
  • 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)
