3 IMMUNITY AND CANCER

4 IMMUNITY AND CANCER Clinical trials with vaccination of ex-vivo generated dendritic cells (DCs) pulsed with tumor antigens have provided a proof-of-principle that therapeutic immunity can be elicited in cancers However Clinical benefit has been observed in only a fraction of cases when measured by regression of tumors in stage IV cancer The next generation of DC vaccines are expected to generate large numbers of high avidity effector CD8+ T cells to overcome regulatory T cells and the suppressive environment established by tumors Therapeutic vaccination protocols with improved DC vaccines in combination with chemotherapy is expected to exploit immunogenic chemotherapy regimens

15 INTERPRETING CLINICAL EFFICACY FOR DC CTs
Pre-mature dismissal of therapy is not suggested if ORR is not high for such a therapy Unrealistic to expect efficient immune responses to eliminate the total tumor burden in a patient with advanced cancer Analysis of improved survival benefits in randomized studies and long-term follow-up is suggested Molecular pathways or chemotherapeutics now considered active based not on only ORR but improved survival and/or time to disease progression A phase III study comparing DC Therapy with standard chemotherapy (DTIC) in melanoma patients showed insignificant ORR in DC arm but post-hoc analysis demonstrated improved survival and performance status in specific phenotype Clinical Trials results suggest that DC vaccination therapy needs to be tailored for pre-identified cohorts of patients. Prolonged survival and good quality of life might be considered a therapeutic success

16 SOME CONCLUSIONS FROM DC CTs
DCs are the critical decision-making cells in the immune response and an attractive target for therapeutic manipulation to enhance otherwise insufficient immune responses to tumor antigens Complexity of the DC system requires rational manipulation to achieve protective or therapeutic immunity Further research needed to analyze the immune responses induced in patients by distinct ex vivo generated DC subsets activated via different pathways Progresses made in the knowledge of DC biology as well as effector/regulatory T cell biology clearly open the avenues for development of considerably improved clinical protocols Possibility of including therapeutic vaccination of metastatic disease and preventive vaccination in patients with resected tumors The ultimate ex vivo-generated therapeutic DC vaccine will be heterogeneous and composed of several subsets, each of which will target a specific immune effector. These ex vivo strategies should help to identify the parameters for DC targeting in vivo, which lead to the next step

17 Apceden™

18 WHAT IS Apceden™ Apceden™ is an autologous (self) monocyte derived Dendritic Cell immunotherapy which nurtures the patient’s own mononuclear cells against cancer specific cells Patients undergo apheresis for collection of blood monocytes. These cells are cultured and processed for the production of mature dendritic cells (DC) against the specific tumor cell type, which are harvested on Day 8. Each dose of APCEDEN™ consists of dendritic cells (CD 80+, 83+, 86+,CD14-) more than 1 million in 15ml 6 doses are given every 2 weeks for first 3 cycles and next 3 cycles are given every 3 weeks.
