May 11th, 2020. Akesobio (HKEX Code: 9926.HK) announced that the first patient has been dosed in a Phase 1 clinical study to evaluate the safety and tolerability of AK117, a novel anti-CD47 monoclonal antibody that targets the CD47-SIRPα axis for the treatment of patients with advanced solid tumors or hematologic malignancies.
“AK117 received IND approval from FDA in April and announced the first patient dosed in Australia today, we are delighted to say that AK117's the global development is making progress smoothly”, said Michelle Xiayu, Chairwoman and CEO of Akesobio, “AK117, with its unique structure can be a next generation anti-CD47 drug with better clinical benefit.. The pre-clinical data so far shows no induction of hemagglutination and reduced phagocytosis of RBCs, while retains its antitumor activity. AK117 will further enrich and advance Akesobio’s innovative product pipeline and increase the flexibility of Akeso’s antibody drugs for the treatment of cancer in combination with other therapies.”
AK117 is a novel anti-CD47 monoclonal antibody developed by Akesobio. Elevated expression of CD47 has been observed in multiple tumor types, which could interact with SIRPα expressed on macrophages. CD47-SIRPα interaction releases a “don’t eat me” signal which prevents phagocytosis of tumor cells by macrophages. Drugs targeting CD47 as monotherapy or combination therapy have shown promising antitumor activities in hematological malignancies and solid tumors, which make CD47 a new hotspot for tumor immunotherapy. However, due to expression of CD47 on red blood cells (RBCs), drugs targeting CD47 could induce phagocytosis of RBCs and hemagglutination, which may limit the full potential of anti-CD47 therapy. AK117, with its unique structure, shows no induction of hemagglutination and reduced phagocytosis of RBCs, while retains its antitumor activity. Therefore, it’s foreseeable that AK117 can be a next generation anti-CD47 drug with better clinical benefit.
