Alligator Bioscience: ADC-1013 clinical Phase I data to be presented at ASCO

Lund, Sweden, May 15, 2019 – Alligator Bioscience (Nasdaq Stockholm: ATORX), today announces that Janssen Biotech, Inc. (Janssen) will present data from a Phase I clinical study of ADC-1013 (JNJ-7107) at the upcoming ASCO Annual meeting held in Chicago on May 31- June 4. The study results show that side effects were generally mild and transient.

The primary aim of the study was safety and to establish a recommended dose for Phase II. The study is still ongoing and has enrolled a total of 95 patients. The maximum tolerated dose has not yet been reached. Doses up to 1200 μg/kg i.v without premedication, and up to 2000 μg/kg with premedication have been shown to be safe and tolerable. Early evidence of clinical activity in this study included a partial response (PR) in a patient with renal cell cancer and 10 patients with prolonged stable disease (SD) ≥6 months.

“I am glad to see the promising safety and tolerability profile of ADC-1013 in patients with cancer. This together with the early signs of clinical activity, gives me great confidence in this CD40 drug candidate”, said Per Norlén, CEO of Alligator Bioscience.

A poster (#171) with the title “A Phase 1 Study to Assess Safety, Pharmacokinetics (PK) and Pharmacodynamics (PD) of JNJ-64457107, a CD40 Agonistic Monoclonal Antibody, in Patients (pts) with Advanced Solid Tumors” will be showcased at ASCO on June 1, 2019 from 8 – 11 a.m. in the session Developmental Immunotherapy and Tumor Immunobiology.

About ADC-1013 (JNJ-7107)
ADC-1013 is a drug candidate intended for immunotherapy of different types of cancer. Results from a previous clinical Phase I first-in-human study performed by Alligator (International Journal of Cancer, showed that ADC-1013 was generally well tolerated. Preclinical data have previously 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.
