Alligator Bioscience receives patent approval for the drug candidate ATOR-1015

LUND, Sweden, Sept. 16, 2020 /PRNewswire/ -- Alligator Bioscience (Nasdaq Stockholm: ATORX) announced today that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,774,150 which covers compositions of matter directed to Alligator's bispecific drug candidate ATOR-1015. The granted patent's earliest expiry year is 2036.

"ATOR-1015 constitutes a new concept, a tumor-localizing bispecific CTLA-4 antibody. Our invention addresses one of the key challenges within immuno-oncology, i.e. the narrow therapeutic window of CTLA-4 drugs. This is now protected by a granted US patent," commented Per Norlén, CEO at Alligator Bioscience.

ATOR-1015 is developed for the treatment of metastatic cancer. Promising safety data from the ongoing ATOR-1015 Phase I clinical study was presented at ASCO in June 2020. The Phase I dose escalation study is planned to be completed during the fourth quarter 2020 and the subsequent Phase Ib efficacy study in malignant melanoma is due to start in 2021.
