Clinical Trial Summary

This phase IB/II trial is designed to investigate the safety and survival benefits for patients with recurrent grade-4 with unmethylated MGMT promoter treated with Bortezomib and Temozolomide in a specific schedule.

Description:

Patients harbouring tumours with functional O6 methylguanine DNA methyltransferase (MGMT) DNA repair enzyme efficiently repair the DNA damage inflicted by Temozolomide and gain limited benefit from this chemotherapy. Bortezomib depletes the MGMT enzyme, restoring the tumour´s susceptibility to Temozolomide, if the chemotherapy is administered in the precise schedule when the MGMT enzyme is depleted. Additionally, Bortezomib inhibits the growth of tumour cells by blocking autophagy flux. Temozolomide causes genotoxic stress in cancer cells that in turn respond by inducing protective processes such as autophagy. If both autophagy and MGMT DNA repair enzyme are blocked a priori, the efficacy of Temozolomide will be enhanced. Thus, pre-treating the tumour with Bortezomib prior to administration of Temozolomide leads to DNA repair enzyme depletion and blockade of autophagy-induced survival signals. The combined effect will sensitize the tumour to therapy, improve chemotherapy efficacy and prolong patient survival outcomes.

Hypothesis: Pretreatment with Bortezomib administered prior to Temozolomide will sensitize recurrent GBM with unmethylated MGMT promoter to standard TMZ in palliative setting.

Objective:

• Assessment of safety and tolerability of Bortezomib administered with Temozolomide.

• Determining the optimal dose of TMZ, when administered as combination therapy

• Estimate the progression free survival (PFS) and overall survival (OS) of patients with recurrent or progressed glioblastoma after pre-treatment with Bortezomib prior to combination with Temozolomide.

Key secondary objectives

• Tumour response to the therapy assessed by RANO and NANO criteria

• Determine physiological, molecular and biochemical changes in blood and tumour tissue that correlate with treatment responses.

• Unfractionated and/or low molecular weight heparin allowed

• Patients previously treated with neurosurgery er eligible for the study

Exclusion Criteria:

• Hypersensitivity to Bortezomib, boron, or mannitol

• Any contraindications for use of temozolomide

• Peripheral neuropathy = grade 2

• Previous treatment with bevacizumab or lomustine alone or as a combination therapy for ralapsed glioblastoma (PCV as primary treatment of low grade glioma, before development of glioblastoma, is allowed)

• Myocardial infarction within the past 6 months

• NYHA class III or IV heart failure

• Uncontrolled angina

• Severe uncontrolled ventricular arrhythmias

• Electrocardiographic evidence of acute ischemia or active conduction system abnormalities

• Known heart failure

• Serious medical or psychiatric illness that would interfere with the study participation including, but not limited to, any of the following:

• Ongoing or active infection requiring IV antibiotics

• Psychiatric illness and/or social situations that would limit compliance with study requirements

• Disorders associated with a significant immunocompromised state (e.g., HIV, systemic lupus erythematosus)

• History of stroke within the past 6 months

• Other malignancy within the past 3 years except completely resected basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy (i.e., cervical cancer), or low-risk prostate cancer after curative therapy

• Significant medical illness that, in the investigator's opinion, cannot be adequately controlled with appropriate therapy or would compromise the patient's ability to tolerate this therapy

• Disease that will obscure toxicity or dangerously alter the drug metabolism

• Viral hepatitis (HBV surface antigen positive) or active hepatitis C infection

• Other investigational drugs must be stopped at least 12 weeks prior to therapy or treatment failure under other experimental therapy must be confirmed before study entry. If progression during other experimental therapy is confirmed, the time interval between previous treatment and BORTEM-17 may be reduced to 4 weeks

Related Conditions & MeSH terms

• Glioblastoma

Intervention

Drug:
• Bortezomib and Temozolomide Phase IB
In the Phase IB of the study the following dose escalation of TMZ will be performed: The first cohort of 3 patients will receive 150 mg/m2 of IMP (TMZ) for 5 days q4w. If one patient in this cohort develops a dose limiting toxicity, another cohort of 3 patients will be treated at the same dose level until 2 or more patients in the group of 3-6 develop DLT.
• Bortezomib and Temozolomide Phase II
The patientes will be treated with the maximum recommended starting dose of Temozolomide and Bortezomib established in the IB phase of the study
