Temozolomide, Surgery, Radiotherapy

Johanna Buchroithner, MD

A randomised, open-label, 2-arm, multi-centre, phase II clinical study with one group receiving standard therapy with Temozolomide, radiotherapy, and Trivax; and a control group receiving standard therapy with Temozolomide and radiotherapy only; after tumour resection of at least 70% in both groups. The hypothesis is based on the assumption that time to progression will be doubled in the treatment group.

Vaccination represents a success story in modern medicine and its principles have been found to be valid in different species, at least in the case of infectious diseases. As of today, there is little reason to believe that this would not be true in the case of tumours. It is now generally acknowledged that human tumours carry a mutational antigenic (non-self) repertoire of immunogenic potential that may be a suitable target for antitumour immune therapy. During the last years accumulating evidence from mouse experiments indicates that one can immunise prophylactically against cancers as effectively as against an infectious agent. However, in contrast to most experimental mouse tumour models, human tumours have in general been within their host for a long time and thus had the opportunity to influence their microenvironment and the larger immunological environment. Antigens capable of mediating specific rejection were found in human as well as in mouse tumours.

Many of the clinical trials using dendritic cell (DC) -based cancer vaccination techniques were designed for the treatment of melanoma. Other important diseases in which DC-based cancer vaccination was studied include prostate cancer, B cell lymphoma, renal cell carcinoma, glioma and glioblastoma, breast and ovarian cancer, gastrointestinal cancer, and selected solid paediatric tumours. In most of these trials some in vivo and/or in vitro evidence for the generation of anti-tumour immunity was found and even complete or partial remission of the tumour was observed in selected cases. The first phase III trial demonstrating the efficacy of DC cancer vaccination for the treatment of prostate cancer was reported recently (www.dendreon.com). Also patients suffering from glioblastoma multiforme appear to benefit from DC cancer immune therapy. The side effects observed in DC cancer vaccinations were usually described to be mild and not limiting the application.

We developed a DC cancer vaccine technology, Trivax, advancing the design of DC cancer immune therapy in one critical aspect. It is the first such vaccine that is enable for releasing the immune modulatory cytokine interleukin (IL) -12. Trivax is comprised of IL-12 secreting DCs and a mixture of protein tumour antigens derived from the individual patient's tumour cells. No synthetic tumour antigen component is involved. Both components of Trivax are derived from the individual patient and are used for the treatment of only this patient. Trivax therefore represents a fully individualised somatic cell therapy medicine. Trimed's early clinical evaluations in patients suffering from kidney cancer, prostate cancer, bone tumours, and malignancies of childhood have confirmed the safety and the feasibility of the Trivax technology.

Glioblastoma multiforme (GBM) (ICD-O M9440/3) is the most malignant astrocytic tumour, composed of poorly differentiated neoplastic astrocytes. Histopathological features include cellular polymorphism, nuclear atypia, brisk mitotic activity, vascular thrombosis, micro-vascular proliferation and necrosis. GBM typically affects patients of various age beginning in childhood and up to high age. It is preferentially located in the cerebral hemispheres. GBM may develop from diffuse astrocytomas WHO grade II or anaplastic astrocytomas (secondary GBM), but more frequently, they manifest after a short clinical history de novo, without evidence of a less malignant precursor lesion (primary GBM). In spite of modern oncological treatment, the prognosis of GBM remains dismal, with a median survival of little over 1 year.

GBM-Vax is a randomised, open-label, 2-arm, multi-centre, phase II clinical study with both groups undergoing surgery and receiving standard therapy with Temozolomide and radiotherapy; and the treatment group that in addition to the standard therapy receives cancer immune therapy with Trivax. Our aim is to extend therapy options presently including surgery, irradiation and Temozolomide with DC cancer vaccination to improve the poor prognosis of patients with GBM.

Primary objective

• Progression free survival measured as percentage of non-progressive patients with newly diagnosed GBM 12 months after a post-operative MRI scan treated according to the current standard (surgical resection, irradiation, oral chemo-therapy with Temozolomide), and Trivax, an autologous DC cancer vaccine charged with autologous tumour protein, as add-on therapy (group A), in comparison to patients receiving standard treatment without Trivax (group B).

Secondary objectives

* Progression free survival measured as percentage of non-progressive patients with newly diagnosed GBM 18 and 24 months after a post-operative MRI scan receiving standard treatment and Trivax as add-on therapy (group A), in comparison to patients receiving standard treatment without Trivax (group B).
* Extension of overall survival of patients with newly diagnosed GBM receiving standard treatment and Trivax as add-on therapy, in comparison to patients receiving standard treatment without Trivax.
* Quality of life in patients treated with Trivax as an add-on therapy using ECOG (Eastern Cooperative Oncology Group) performance status compared to qual-ity of life of patients receiving standard therapy (for study patients older 18 years).

Number of subjects In total, 56 patients will be enrolled in the study. The study consists of 2 arms and at least 28 patients should be randomly assigned to one of the two arms. It is expected to recruit the study patients within a period of one year. Randomisation is based on stratification according to study sites at a 1:1 ratio. Patients younger than 18 years will not be randomised but will all receive add-on therapy with Trivax. We feel that it would be not just to expect from children to understand and accept that there is a new treatment available but only every second patient will receive it. Obviously, patients younger than 18 years will not be analysed together with adult patients in the context of the study; and paediatric patients will not count towards the recruiting number of 2 x 28. Thus, the results obtained in paediatric GBM patients will not influence the outcome of the study in patients older than 18 years.

Dendritic Cell Cancer Vaccine for High-grade Glioma

First Line Standard Therapy of Glioblastoma Multiforme With or Without add-on Treatment With Trivax, an Anti-tumour Immune Therapy Based on Tumour-lysate Charged Dendritic Cells

Progression free survival measured as percentage of non-progressive patients with newly diagnosed GBM 12 months after a post-operative MRI scan treated according to the current standard (surgical resection, irradiation, oral chemotherapy with Temozolomide), and Trivax, an autologous DC cancer vaccine charged with autologous tumour protein, as add-on therapy (group A), in comparison to patients receiving standard treatment without Trivax (group B).

Quality of life in patients treated with Trivax as an add-on therapy using ECOG (Eastern Cooperative Oncology Group) performance status compared to quality of life of patients receiving standard therapy.

Progression free survival measured as percentage of non-progressive patients at 18 and 24 months post initiation of treat-ment.

The percentage of survival will be assessed at 12, 18, and 24 months.
