Predicting Response Patterns to Treatment in Glioblastoma (GBM) Patients

Predicting Response Patterns to Treatment in Glioblastoma (GBM) Oncology Patients Based on Host Response Evaluation During Anti-cancer Treatments

PROPHETIC GBM - Predicting response patterns to treatment in Glioblastoma (GBM) oncology patients based on host response evaluation during anti-cancer treatments

The goal of this research study is identify new host response proteins, pathways and mechanisms that are associated with responsiveness to GBM treatment modalities.

This will serve as a tool for physicians when making treatment decisions. The investigators also aim to identify the metabolic pathways that could lead to better therapeutic options. The patients will be given their treatment according to the institute's standard of care. The patients will provide up to 5 blood samples and clinical data will be collected from their medical records.

The data obtained from the blood samples and the medical records of the patients will be used to search for potential mechanisms that are involved in response to treatment, and to identify potential targets to increase the response, and hence, increase treatment effectiveness or suggest potential new treatments.

Inclusion Criteria:

1. Provision of informed consent prior to any study-specific procedures.

2. Male or female aged at least 18 years.

3. KPS not less than 50.

4. Normal hematologic, renal and liver function:

   1. Absolute neutrophil count above 1500/mm3, platelets above 100,000/mm3, hemoglobin above 9 g/dL;
   2. Creatinine concentration not more than 1.4 mg/dL, or creatinine clearance above 40 mL/min;
   3. Total bilirubin below 1.5 mg/dL, ALT+ AST levels not more than 3 times above the upper normal limit.

5. Patients planned to receive standard of care TMZ+RT treatment; TTF therapy during RT is permitted.

Exclusion Criteria:

1. Any concurrent and/or other active malignancy that has required systemic treatment within 2 years of surgery. Except for basal cell carcinomas and squamous cell carcinomas that have been completely excised and considered cured at least 12 months prior to screening, and carcinoma in situ of the cervix that have been completely excised and cured at least 5 years prior to screening.
2. Participation in another clinical trial which includes an investigational drug.
3. Generalized impairment or mental incompetence that would render the patient unable to understand his/her participation in the study.
