简要总结
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).
详细描述
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).

入选标准
- •To be eligible for inclusion into this study, each patient must fulfil the following inclusion criteria ≤ 28 days prior to the anticipated surgery date:
- •Malignant glioma (WHO grade III or IV) who have undergone conventional treatment, including surgery (gross total resection or unintentional partial resection with residual tumour) or biopsy (with residual tumour), and/or radiation therapy, and/or chemotherapy, and/or Temozolomide and have progressive and/or multiple recurrent GBM. Preoperative assessment by clinical presentation and CT/MRI appearance of the lesion will identify suitable candidates.
- •Age 18-75 years.
- •Karnofsky >70 (see APPENDIX C: EXAMPLE OF PERFORMANCE STATUS: KARNOFSKY SCALE).
- •Stable dose of corticosteroids no longer than 4 weeks prior to enrolment.
- •Females of childbearing potential must have a negative serum or urine pregnancy test.
- •Females who have undergone surgical sterilization or who have been postmenopausal for at least 2 years are not considered to be of childbearing potential.
- •Females of childbearing potential and males who have not undergone surgical sterilization must agree to practice a form of effective contraception prior to entry into the study and for 1 month after the end of infusion.
- •Effective contraception:
- •If female, is non-lactating, has a negative urine pregnancy test result, and does not plan on becoming pregnant during the study, or not of childbearing potential (hysterectomy or tubal ligation at least 6 months prior to entry to the study or post-menopausal for 1 year); if of childbearing potential (including peri-menopausal women who have had a menstrual period within one year) must practice or be willing to continue to practice acceptable birth control from screening and until 1 month after the study medication has been discontinued.
- •Acceptable birth control includes:
- •Combined (oestrogen and progestogen containing) hormonal contraception;
- •Associated with inhibition of ovulation; oral OR intravaginal OR transdermal;
- •Progestogen-only hormonal contraception associated with inhibition of ovulation: oral OR injectable OR implantable;
- •Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the primary mode of action;
- •Intrauterine device (IUD);
- •Intrauterine hormone-releasing system (IUS);
- •Bilateral tubal occlusion;
- •Vasectomised partner;
- •Sexual abstinence;
- •Male or female condom with or without spermicide;
- •Cap, diaphragm or sponge with spermicide. Complies with The Heads of Medicines Agencies (HMA) Recommendations Related to Contraception and Pregnancy Testing in Clinical Trials (Sept 2014).
- •The definition of effective contraception will be based on the judgment of the investigator.
- •Ability to understand and the willingness to sign a written informed consent document.
排除标准
- •To be eligible for inclusion into this study, each patient must violate none of the following exclusion criteria ≤ 28 days prior to the anticipated surgery date:

- •Patients who are receiving any other investigational agents.
- •Life expectancy <3 months
- •Haematological dysfunction defined as:
- •White blood cell (WBC) count <3.0 x 109/L;
- •Absolute neutrophil count <1.5 x 109/L;
- •Haemoglobin level <10.0 g/dL;
- •Platelet count <100 x 109/L.
- •Liver dysfunction defined as:
- •Aspartate transaminase (AST) >2.5 x the upper limit of normal (ULN) for age and gender;
- •Alanine transaminase (ALT) >2.5 x the ULN for age and gender;
