Notes to editors

About ADC-1013

ADC-1013 is a drug candidate intended for immunotherapy of different types of cancer. Pre-clinical data have shown that the ADC-1013 antibody effectively activates T-cells, mediated through binding to the co-stimulatory receptor CD40 on dendritic cells. The increased T cell activation enables the immune system to attack the cancer. In addition, since some cancer cells express CD40 on the surface, ADC-1013 may act also through a secondary mechanism of action killing cancer cells directly. 

In August 2015, Alligator licensed global development rights for ADC-1013 to Janssen Biotech Inc. In October 2016, Janssen Biotech, Inc. started a second phase I clinical study (ClinicalTrials: NCT02829099). That study is an intravenous dose escalation study with ADC-1013 (JNJ-64457107).

About the ADC-1013 clinical Phase I study

The study to be presented is a multicenter, open-label phase I study in patients with advanced solid tumors evaluating safety and tolerability, pharmacokinetics, immunogenicity, biomarker response and clinical response. The study is a dose-escalation study involving intratumoral and intravenous administration of ADC-1013 at five hospitals in Sweden, Denmark and the UK. The study was performed by Alligator and includes 24 patients and ten different tumor types. For further information, please visit; NCT02379741.
