Alligator Bioscience Publishes Clinical Phase I Data for ADC-1013 in the International Journal of Cancer

First-in-human study with intratumoral administration of a CD40 agonistic antibody, ADC-1013, in advanced solid malignancies

LUND, Sweden, Jan. 29, 2019 /PRNewswire/ -- Alligator Bioscience (Nasdaq Stockholm: ATORX), announces the publication of the results from a clinical phase I first-in-human study of the CD40 agonistic antibody ADC-1013 (JNJ-64457107). The top line data from this study was presented at the Society for Immunotherapy of Cancer (SITC) in November 2017.

The results show that the agonistic anti-CD40 antibody ADC-1013 is safe and tolerated at clinically relevant dose levels. Furthermore, the pharmacodynamic effects and the preclinical data support the further clinical development of ADC-1013 against cancer and demonstrate the potential of ADC-1013 as a combination therapy with PD-1 targeted therapies.

About ADC-1013

ADC-1013 is a drug candidate intended for immunotherapy of different types of cancer. Preclinical 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 (JNJ-64457107) to Janssen Biotech, Inc. Currently, Janssen Biotech, Inc. performs a phase I dose-escalation clinical study (ClinicalTrials: NCT02829099) with intravenous administration of ADC-1013.
