Innovent Presents Phase 1b Clinical Data of IBI188 (Anti-CD47 Monoclonal Antibody) at the 2022 American Society of Hematology Annual Meeting

ROCKVILLE, Md. and SUZHOU, China, Dec. 11, 2022 /PRNewswire/ — Innovent Biologics, Inc. (“Innovent”) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncology, autoimmune, metabolic, ophthalmology and other major diseases, announced that clinical data of IBI188 (anti-CD47 monoclonal antibody) as first-line treatment in newly diagnosed higher risk myelodysplastic syndrome (MDS) is presented at the 2022 American Society of Hematology (ASH) Annual Meeting, held Dec 10-13, 2022.

Efficacy and Safety of IBI188 (anti-CD47 mAb) in Combination with Azacitidine (AZA) in First Line Newly Diagnosed Higher Risk Myelodysplastic Syndrome (MDS): Updated Results from a Phase Ib Study

IBI188 is an IgG4 recombinant human anti-CD47 monoclonal antibody developed by Innovent Biologics. The Phase Ib study aims to evaluate the efficacy and safety of IBI188 in combination with AZA as first line therapy for newly diagnosed higher risk MDS.

As of the data cutoff date (Oct 20, 2022), 93 treatment-naïve newly diagnosed higher risk MDS patients received IBI188 (from 0.1 mg/kg priming dose to 30mg/kg maintenance, QW) combined with AZA. 30 patients had received treatment ≥ 6 cycles. The Objective Response Rate (ORR) was 100% (30/30), complete response rate (CRR) was 63.3% (19/30). 42 patients had received treatment ≥ 4 cycles, ORR was 97.6% (41/42), CRR was 45.2% (19/42). 49 patients had received treatment ≥ 3 cycles, ORR was 93.9% (46/49), CRR was 38.8% (19/49). The median duration of response was not reached yet. For safety results, 88 (94.6%) patients experienced at least 1 treatment-related adverse event (TRAE). The most common TRAEs were platelet count decreased, anemia, white blood cell count decreased, neutrophil count decreased, etc. TRAEs leading to discontinuation of IBI188 occurred in 7 (7.5%) patients. IBI188 combined AZA in first line newly diagnosed higher risk MDS continues showing robust anti-tumor activity and favorable safety. The study is ongoing with the clinical data continuing to mature and will be disclosed in the future academic conference/journals.

Professor Miao Miao, The First Affiliated Hospital of Suzhou University, stated: “Data showed that the incidence of MDS globally is about (2~12)/100 000 per year, and in China the incidence is approximately (0.23~1.51)/100 000 per year. The incidence rates increase significantly along with age. The median overall survival of higher risk MDS is only 0.8-1.6 years and 25%-30% patients develop into AML if untreated. Hypomethylating agents, include AZA, were the most common used drugs in the treatment of higher risk MDS, but only 40%-50% patients can be benefit from this treatment. Despite of the efficacy, the disease will relapse within 2 years and the median overall survival after recurrence is only about 4.3 months. IBI188 plus AZA indicate promising antitumor activity and manageable safety profile in untreated higher risk MDS patients, suggesting that it is worth further exploring the safety and efficacy of IBI188 combination therapy in this indication.”

Dr. Hui Zhou, Senior Vice President of Innovent, stated: “We are pleased to present our clinical development updates at the 2022 ASH Meeting. IBI188 in combination with AZA demonstrated encouraging efficacy and safety data in newly diagnosed higher risk MDS. We will continue to update on PoC data readout for IBI188. As immunotherapy moves into the next era, we are actively advancing the development of next-generation immune checkpoint inhibitors, and we hope it could benefit more patients in need soon.”

About IBI188

IBI110 is an IgG4 recombinant human anti-CD47 monoclonal antibody independently developed by Innovent Biologics. Based on the mechanism of action and preclinical data of IBI188, it is assumed that IBI188 can inhibit CD47 binding to SIRPα expressed on the surface of macrophages to achieve phagocytosis enhancement and anti-tumor effect. Based on the urgent clinical needs, Innovent has carried out clinical studies to explore PK/PD characteristics of IBI188 single agent and combined with hypomethylating agents in human body as well as its efficacy and safety in various advanced tumors (solid tumors and hematological malignancies).
