Efficacy and Safety - The HARMONI trial demonstrated a statistically significant improvement in progression-free survival (PFS) compared to Pembrolizumab[7]. - Ivonescimab demonstrated a median progression-free survival (mPFS) of 11.14 months compared to 5.82 months for pembrolizumab, showing a 5.3 month improvement[27]. - The hazard ratio for progression-free survival (PFS) between Ivonescimab and pembrolizumab was 0.51, with a p-value of <0.0001, indicating a statistically significant advantage for Ivonescimab[27]. - In a Phase III study, Ivonescimab showed a clinically meaningful improvement in PFS across major clinical subgroups, with a stratified hazard ratio of 0.46[28]. - The safety profile of Ivonescimab was consistent with prior studies, with treatment-related adverse events (TRAEs) reported at 29.9% for Ivonescimab and 28.1% for pembrolizumab[36]. - In the 2L+ EGFRm NSCLC study, Ivonescimab combined with chemotherapy resulted in an mPFS of 7.1 months compared to 4.8 months for placebo plus chemotherapy, with a hazard ratio of 0.46 and a p-value of <0.001[48]. - Ivonescimab demonstrated a 43.6% pathologic complete response (pCR) rate in Phase II studies for perioperative resectable non-small cell lung cancer (NSCLC) with a median progression-free survival (PFS) of 80.3% at 12 months[58]. - In the first-line setting for metastatic colorectal cancer (CRC), Ivonescimab achieved an overall response rate (ORR) of 81.8% and a disease control rate (DCR) of 100% with a 9-month PFS rate of 81.4%[60]. - For first-line PD-L1 positive recurrent/metastatic head and neck squamous cell carcinoma (HNSCC), Ivonescimab reported an ORR of 60% and a DCR of 90% with a median PFS of 7.1 months[65]. - In the first-line triple-negative breast cancer (TNBC) setting, Ivonescimab achieved an ORR of 79.3% and a 6-month PFS rate of 83.3%[67]. - The safety profile of Ivonescimab in the HARMONi-A study was generally well tolerated, with a low rate of treatment discontinuation and no unexpected adverse events reported[23]. Regulatory Status and Market Potential - Ivonescimab is approved in China and is expected to have top-line data available by mid-2025[20]. - Ivonescimab is currently not approved by any regulatory authority other than China's National Medical Products Administration (NMPA)[27]. - Ivonescimab is currently only approved by China's National Medical Products Administration (NMPA) and is still under investigation in other markets[61]. - The global market opportunity for checkpoint inhibitors (CPI) in NSCLC is projected to exceed 90 billion by 2028, with Ivonescimab positioned to capture significant market share[70]. Company Strategy - The company emphasizes a mission to improve quality of life and address serious unmet medical needs[3]. - The company is actively pursuing collaborations and potential acquisitions to enhance its drug development pipeline[2]. - Akeso is expanding its global clinical development plan for Ivonescimab, indicating a strong commitment to advancing its pipeline[69].
