Milestones of ivonescimab:

May 2024:
Ivonescimab was granted marketing approval for the treatment of epidermal growth factor receptor ("EGFR") mutated locally advanced or metastatic non-squamous non-small cell lung cancer ("nsq-NSCLC"), making it the world's first approved PD-1/VEGF bi-specific antibody.

May 31:
At a prespecified interim analysis conducted by an independent Data Monitoring Committee, ivonescimab demonstrated a statistically significant and clinically meaningful improvement in PFS by blinded independent radiology review committee (BICR) compared to pembrolizumab, and the hazard ratio (HR) was significantly better than expected. There are no known Phase III clinical trials in NSCLC which have shown a statistically significant improvement compared to pembrolizumab in a head-to-head setting.

June 01:
Interim result of the Phase III study of ivonescimab combined with platinum-doublet chemotherapy in patients with  EGFR-mutant non-squamous non-small cell lung cancer who progressed on EGFR-TKIs treatment (HARMONi-A ), was presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, and the study was ranked as the top report on the TOP 10 list of lung cancer at ASCO by OncoAlert, an international cancer support organization. On the same day, the research findings were also published simultaneously in the JAMA journal.

July 25:
Akeso's partner, Summit Therapeutics Inc. (NASDAQ: SMMT) ("Summit,") announced a strategic five-year collaboration agreement with The University of Texas MD Anderson Cancer Center (MD Anderson) for the purpose of accelerating the development in certain types of renal cell carcinoma, colorectal cancer, skin cancer, and breast cancer.

July 29:
The supplemental New Drug Application (sNDA) for ivonescimab as a monotherapy for first-line treatment of PD-L1 positive (PD-L1 TPS≥1%) locally advanced or metastatic non-small cell lung cancer (NSCLC), has been accepted by the China National Medical Products Administration (NMPA). This new indication application for ivonescimab is based on the HARMONi-2 (AK112-303) study.

August 02:
The supplemental New Drug Application (sNDA) for ivonescimab monotherapy for first-line treatment of PD-L1 positive (PD-L1 TPS≥1%) locally advanced or metastatic NSCLC was accepted by China NMPA with priority review.
