A Dose Escalation Phase I Study Of Human- Recombinant Bone Morphogenetic Protein 4 Administrated Via CED In GBM Patients


Brief description of study

The purpose of the study is to evaluate the feasibility and safety of intra-tumor and interstitial therapy with hBMP4 in increasing doses in patients with progressive and/or multiple recurrent Glioblastoma multiforme (GBM).

Detailed Study Description

This multicentre, open-label, dose escalating, Phase I study will enrol approximately 18 patients with progressive and/or multiple recurrent GBM, who after failure of standard therapies will receive GMP Human- recombinant Bone Morphogenetic Protein 4 via intra-tumour and interstitial delivery by CED. Patients will undergo a resection or biopsy of the tumour, confirmation of viable malignant glioma tumour cells during frozen section performed by the institutional pathologists, and intra-tumor and interstitial placement under neuronavigational guidance of 2 or 3 catheters. No catheters will be placed at time of resection. After resection, catheters will be placed during a separate procedure several days later based upon the patient's condition as determined by both a clinical examination and routine MRI scan. Patients will receive intra-tumour and interstitial CED of increasing amounts of hrBMP4 solutions (at a starting dose of 0.5 mg) and 1:70 gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) in a total of 44-66 ml over up to 4-6 days at the discretion of the investigator. Gd-DTPA will be co-infused with hrBMP4 to determine the extent of intra-tumour and interstitial drug delivery. Patients will be hospitalized from the time of the original surgery until the end of infusion of hrBMP4. Patients will be followed for the duration of the study. The primary endpoint of the study is monitoring feasibility and patient safety for the incidence of Dose-Limiting Toxicity (DLT) following intra-tumour and interstitial therapy with hrBMP4 and to determine whether there is a Maximum Tolerated Dose (MTD).
