Descriptive Information
Brief Title  ICMJE Olaptesed (NOX-A12) Alone and in Combination With Pembrolizumab in Colorectal and Pancreatic Cancer
Official Title  ICMJE A Two-part, Open-label Phase 1/2 Study to Evaluate Pharmacodynamic Effects and Safety of Olaptesed Pegol Monotherapy and Safety and Efficacy of Olaptesed Pegol / Pembrolizumab Combination Therapy in Metastatic Colorectal and Pancreatic Cancer
Brief Summary The purpose of this study is to show that the type, number and/or distribution of tumor metastases infiltrating immune cells such as cytotoxic T cells and/or the cytokine signature in the tumor metastases can be modulated by treatment with olaptesed pegol and to explore safety, tolerability and efficacy of olaptesed pegol in combination with pembrolizumab as a basis for subsequent studies in combination with immunotherapies, in particular checkpoint inhibitors.
Detailed Description Olaptesed pegol (NOX-A12) targets a key chemokine in the tumor microenvironment, CXCL12, which is naturally involved in the homeostasis of blood and immune cells. In cancer, CXCL12 acts as a communication bridge between tumor cells and their environment. In particular, it confers resistance to checkpoint inhibitors through T-cell exclusion in preclinical models. The hypothesis is that inactivation of CXCL12 by olaptesed pegol induces changes in the tumor microenvironment of patients with colorectal and pancreatic cancer which render the tumors more susceptible to immuno-oncological approaches such as checkpoint inhibition.
