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.

We plan to recruit up to 100 mCRC patients with baseline resectable liver-restricted metastases (mCRC-LR) without evidence of extra-hepatic metastases, with primary tumor already or to be resected (metachronous or synchronous disease), planned to receive upfront FOLFOX-based preoperative neoadjuvant systemic chemotherapy, who achieved no-evidence of disease (NED) in the abdomen by standard imaging.

In North America, colorectal cancer patients with resectable liver-restricted metastases (mCRC-LR) are treated with approximately 6 months of preoperative systemic multi-agent chemotherapy. Actuarial data however supports that approximately 20% of mCRC-LR patients can be cured without as much systemic chemotherapy. Prospective phase II-III trials also support that awaiting recurrence to initiate further metastases-targeted or systemic treatment may provide patients with longer overall survival while avoiding toxicities in those without recurrence.

The general objective of this single-centre, prospective observational cohort study in 100 mCRC-LR patients treated with curative intent along standard of care (SOC), is to obtain real-world data on administered therapies, selected complications, and oncological outcomes, while longitudinally collecting biospecimens to enable correlative research investigating early biological markers of treatment resistance and recurrence.

Cryopreservation of sequential blood derivatives, tumor tissue, and stool samples will allow investigation of circulating tumor DNA (ctDNA), T-cell receptor repertoire, somatic cancer mutations, immune and other gene expression, gut microbiome, and soluble factors.

The first biological marker that will be investigated in correlative research will be longitudinal measurements of ctDNA targeting 30 oncogenes, 23 axons, and 146 hotspots (Follow It assay, Canexia Health). Additional biological markers will be defined in subsequent amendments to this protocol.

The results are expected to provide important insights for the design of future trials investigating ways to personalize therapy, such as to: a) avoid the unnecessary use of neoadjuvant or adjuvant systemic chemotherapy, b) avoid morbid hepatectomies in patients unlikely to benefit, c) test novel preoperative therapies in patients more likely to benefit, and d) modulate the intensity of follow-up.

* Serial blood samples processed to obtain plasma for ctDNA and soluble factor research, buffy coat for genomic research, and mononuclear cells for live cells immune assays;
* Tumor samples processed to allow genomic, proteomic and live cell research;
* Adjacent non-tumoral tissue to allow genomic, proteomic and live cell research;
* Stool samples at baseline and post neoadjuvant chemotherapy to allow metagenomics research.

The central hypothesis for this study is that it is safe and feasible to administer intraluminal photodynamic therapy (PDT) to colon cancers by colonoscopy to induce localized inflammatory/immune response. The objective is to demonstrate the feasibility and safety of PDT to colon cancer patients administered before surgery and to characterize the inflammatory/immune response at the tumor site and systemically. The long-term objective of these studies is to modify he natural biology of colorectal cancers and improve patient survival.

The central hypothesis for this study is that it is safe and feasible to administer intraluminal photodynamic therapy (PDT) to colon cancers, via colonoscopy, in the neoadjuvant setting to induce localized tumor cell death and an inflammatory/immune response with an increased Th1 component, utilizing 5-ALA as a photosensitizer. The objective is to conduct an initial phase I/II clinical study to demonstrate the feasibility and safety of colonoscopic, neoadjuvant intraluminal PDT to colon cancer patients administered 96 hours pre-resection, to characterize the inflammatory/immune response at the PDT treated tumor site, and to evaluate the systemic anti-tumor immune response. The long-term objective of these studies is to provide an easily administered, adjunctive, therapeutic maneuver that lacks systemic toxicity, with the potential to modulate the natural biology of colorectal cancers that have not elicited a favorable anti-tumor immune response and to improve patient survival.

A Study of Neoadjuvant Photodynamic Immunomodulation for Colon Cancer

A Phase I/II Study of Neoadjuvant Photodynamic Immunomodulation for Colon Cancer

Define biologic efficacy of PDT in relation to generation of an immune response at the tumor site and systemically. This will be measured by degree of dendritic cell infiltration into tumor and regional lymph nodes, and degree of systemic immunity directed against colon cancer antigens immediately post procedure and after 6 months.

Safety will be evaluated from enrollment through 6 months. This will be measured by proportion of patients completing planned surgery, proportion of patients experiencing grade 3 or 4 toxicities, and lack of observation of serious adverse events related to the study procedure.

Quality of life will be evaluated 6 months following completion of participation in the study

Immunologic parameters will be monitored following completion of the study as a measure of sustained immunity
