Significant Phase II Breakthrough for Akeso's Ivonescimab in NSCLC
Akeso's Promising Results with Ivonescimab for Lung Cancer
Akeso (9926.HK) has recently shared exciting findings from the Phase II study of ivonescimab, a groundbreaking PD-1/VEGF bispecific antibody designed to treat resectable non-small cell lung cancer (NSCLC). This study was highlighted during a key oral session at the 25th World Conference on Lung Cancer (WCLC), marking ivonescimab's third international presentation in 2024.
Overview of the Phase II Study
The AK112-205 study involved 60 patients with NSCLC, primarily in stage III, with a significant number classified as N+ stage. Impressively, 70% of these N+ stage patients were categorized as N2 stage. The results revealed that 49 patients successfully underwent surgery, achieving all R0 resections. The outcomes were encouraging, with a substantial percentage of patients experiencing pathological complete response (pCR) and major pathological response (MPR) following treatment with ivonescimab.
Evaluation of Treatment Responses
Upon reviewing the results, it became clear that the group receiving ivonescimab in combination with chemotherapy had better MPR and pCR rates compared to those treated with ivonescimab alone. Specifically, the combination therapy achieved an overall pCR rate of 43.6% and an MPR rate of 71.8%. Notably, recent updates indicate that these rates have further improved, especially in patients with squamous NSCLC, where pCR and MPR rates have risen to 63.6% and 84.1%, respectively.
Safety Profile and Emerging Event-Free Survival Data
The safety profile of ivonescimab was found to be manageable, with no reported treatment-related adverse events (TRAEs) causing surgery delays or complications. While data on Event-Free Survival (EFS) is still being gathered, there is promising evidence suggesting a strong link between pCR rates and EFS outcomes, indicating the potential for positive long-term effects from the treatment.
Understanding Ivonescimab and Its Unique Mechanism
Ivonescimab is a pioneering bispecific immunotherapy developed by Akeso. It has received regulatory approval in China for certain NSCLC patient populations and is recognized for its unique dual therapeutic mechanism that combines cancer immunotherapy with anti-angiogenesis.
Global Licensing and Ongoing Research
In addition, Akeso has entered into a licensing agreement with Summit Therapeutics, granting them exclusive rights to develop and commercialize ivonescimab in several regions, including the United States and Europe. This strategic partnership aims to broaden the availability of this promising therapy.
Future Directions and Clinical Trials
The journey for ivonescimab continues with several ongoing Phase III trials, including comparisons with pembrolizumab monotherapy and various combinations for treating squamous NSCLC. Akeso is actively conducting multiple studies across different cancer types, demonstrating a strong commitment to unlocking ivonescimab's full potential.
