Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Autologous dendritic cells cultured from peripheral white blood cells and loaded in vitro with irradiated autologous tumour tissue obtained by surgery, day 0. Surgery is often performed to debulk recurrent tumour. There is no "standard" treatment for recurrent GBM and outwith trials, each case is assessed on individual circumstances. Suitability for second surgery is however a prerequisite of this study.
The dendritic cell-based vaccines (DCV) will be administered intradermally. Patients will receive an initial priming course of three DC vaccinations of 4 x 10^6 cells, administered at week 3, 5 and 7. Further booster DCV vaccinations (1 x 10^6 cells) will start at week 10 and then alternate with courses of temozolomide on a 28 day cycle. Patients will receive a maximum of 6 booster DCV vaccinations over a period of 6 months.
Temozolomide will be administered at an adjuvant dose of 150-200 mg/m2 Body Surface Area (BSA) for 5 days every 28 days, a maximum of 6 cycles of Temozolomide over a period of 6 months, with total duration of the treatment up to 26 weeks.
The 6 cycles of boost DCV vaccine alternate fortnightly with the 6 cycles of Temozolomide.

Outcomes
Primary outcome [1] 259768 0
Feasibility of using resected tissue from recurrent Temozolomide-treated GBM patients to generate autologous, tumour antigen-loaded, DCV. This outcome will be assessed by percentage of successful vaccines produced.
Timepoint [1] 259768 0
At completion of vaccine (DCV) production.
Primary outcome [2] 259769 0
Feasibility of treating recurrent GBM with combined surgery, DC immunotherapy and Temozolomide chemotherapy as assessed by percentage of study patients completing priming course of DCV and 2 cycles of Temozolomide.
Timepoint [2] 259769 0
At completion of priming course of DCV and 2 cycles of Temozolomide.
Primary outcome [3] 259770 0
Safety of treatment (as assessed by the frequency of premature withdrawal due to serious adverse events). Serious adverse events related to autologous dendritic cell vaccination are very rare. There is a small risk of anaphylaxis. Patients are monitored for half an hour after each vaccine prior to discharging home. There are no other serious adverse events expected related to the vaccine. Serious adverse events related to Temozolomide are also rare with neutropenia and thrombocytopenia being the most common occurring in up to 10% of patients. Given that all patients on this study have already demonstrated their tolerance to Temozolomide during their adjuvant treatment, the expectation is that serious adverse events related to Temozolomide would be less than the documented incidence.
Timepoint [3] 259770 0
3 months following completion of all study treatments.
Secondary outcome [1] 268542 0
Radiological response rate to salvage Temozolomide following DCV-treatment relative to salvage Temozolomide alone in historical controls. This outcome will be assessed by MRI
Timepoint [1] 268542 0
After every 2 cycles of Temozolomide.
Secondary outcome [2] 268543 0
Percent progression-free survival at 6 months (PFS6mo) of patients receiving salvage Temozolomide therapy following DCV-treatment relative to salvage Temozolomide alone in historical controls as assessed by clinical assessment by the clinican and MRI
Timepoint [2] 268543 0
6 months post-surgery.
Secondary outcome [3] 268544 0
Tolerability of treatment (Quality of Life assessment by questionnaire).
Timepoint [3] 268544 0
At several timepoints during the study (baseline, week 3, 8, 14 and 22) and after completion of treatment, thereafter at 8 weekly intervals till progressive disease.
Secondary outcome [4] 268545 0
Assessments of vaccine-generated immune responses by self reporting and assessments by trial staff
Timepoint [4] 268545 0
In vitro analysis of tumour-specific immune response in blood pre-vaccination, 2 and 5 weeks after initial vaccination, and every 4 weeks thereafter until 6 cycles of Temozolomide completed, or patient removed from trial. Analysis of delayed type hypersensitivity at day 33 after initial vaccination.

Eligibility
Key inclusion criteria

2. Confirmed diagnosis of WHO Grade 4 Diffuse Astrocytoma (also known as Glioblastoma Multiforme) at original presentation and has relapsed.

3. Has completed treatment with external beam radiotherapy and concomitant Temozolomide, and at least the first 3 cycles of adjuvant Temozolomide.

4. Tumour is surgically accessible with acceptable risk of morbidity.

5. Has at least 1cm3 tumour tissue available as source for tumour antigen.

6. ECOG Performance Status = 2

7. Geographically accessible to the Wellington Blood and Cancer Centre and/or prepared to travel regularly to Wellington for treatment and follow-up for the duration of the study.

8. If fertile, prepared to use contraception for the duration of the trial. Postmenopausal women must have been amenorrhoea for at least 12 months to be considered of non-childbearing potential.

Can healthy volunteers participate?
No
Key exclusion criteria
1. Pregnant or breastfeeding women.

2. Diagnosis of another malignancy within 5 years or presence of other serious unstable medical condition.
