| [02-November-2025] |
HONG KONG, Nov. 2, 2025 /PRNewswire/ -- Akeso (9926.HK) announced that its first-in-class bispecific antibody, ivonescimab (PD-1/VEGF bispecific antibody), in combination with chemotherapy for first-line treatment of triple-negative breast cancer (TNBC) has been granted Breakthrough Therapy Designation (BTD) by the Center for Drug Evaluation (CDE) from China's National Medical Products Administration (NMPA). The Phase III multicenter, randomized, double-blind clinical trial (HARMONi-BC1/AK112-308) for this combination therapy is ongoing in China. The BTD designation is expected to further expedite the clinical development and regulatory approval process of ivonescimab for the treatment of TNBC. This marks the fourth BTD granted by the CDE for ivonescimab. The previous three designations include:
Receiving four Breakthrough Therapy Designations affirms ivonescimab's substantial clinical benefit across multiple major cancer types and reinforces Akeso's commitment to addressing critical unmet medical needs. The therapy is currently advancing in 14 Phase III clinical trials worldwide, including four international multicenter studies. These large pivotal studies, backed by repeated regulatory recognition, position ivonescimab to deliver transformative, life-saving outcomes for patients worldwide.

About 依达方 ® (PD-1/VEGF Bispecific, Ivonescimab) Ivonescimab is a first-in-class, PD-1/VEGF bispecific immuno-oncology agent developed by Akeso. In May 2024, it received approval from the China National Medical Products Administration (NMPA) for the treatment of locally advanced or metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) after EGFR-TKI therapy. This approval made ivonescimab the world's first bispecific antibody based on a synergistic "immunotherapy plus anti-angiogenesis" mechanism. In November 2024, ivonescimab was also included in China's National Reimbursement Drug List (NRDL). Additionally, ivonescimab has been approved as a first-line treatment for advanced NSCLC with positive PD-L1 expression. In the Phase III HARMONi-2 study, ivonescimab demonstrated superior efficacy compared to pembrolizumab, resulting in significantly improved clinical outcomes. In 2025, the final overall survival (OS) analysis from the HARMONi-A study showed that ivonescimab met the OS endpoint, providing clinically meaningful and statistically significant OS benefits. As the first final OS analysis in a Phase III trial of ivonescimab, these results reaffirm the agent's groundbreaking value in both progression-free survival (PFS) and overall survival for patients. Moreover, a head-to-head Phase III trial comparing ivonescimab plus chemotherapy to tislelizumab plus chemotherapy in first-line treatment for squamous NSCLC also yielded promising results. These findings position ivonescimab as a substantial clinical breakthrough whether in comparison to PD-1 monotherapy in immuno-oncology, the current standard of care (SOC) of PD-1 inhibitors combined with chemotherapy, or VEGF-targeted therapies in the anti-angiogenesis field. This underscores ivonescimab's significant potential in cancer treatment. As ivonescimab continues to demonstrate substantial clinical value and the potential to redefine treatment standards, its presence in key immuno-oncology indications is expanding rapidly. In lung cancer, the most prevalent cancer globally, ivonescimab is currently involved in 8 registrational/Phase III clinical studies, including:
In other major tumor types, ivonescimab is rapidly advancing first-line indications with ongoing Phase III trials in:
In the challenging area of cold tumors, ivonescimab has received its fourth Breakthrough Therapy Designation for first-line triple-negative breast cancer. Additionally, Phase III studies are underway for first-line MSS/pMMR colorectal cancer (which accounts for 95% of CRC cases) and first-line pancreatic cancer. Further Phase III studies are also being prepared. With nearly 20 Phase II studies across more than 10 additional indications, ivonescimab has established a robust data foundation to support the rapid global expansion of Phase III trials.
