Akeso's Cadonilimab Shows Promise for NSCLC Patients

Promising Results for Cadonilimab in NSCLC Treatment

In a recent oral presentation, the results of a groundbreaking study involving Akeso, Inc.'s cadonilimab, a PD-1/CTLA-4 bispecific antibody, were highlighted at a major cancer conference. The focus of this research was on its impact on patients suffering from advanced or metastatic non-small cell lung cancer (NSCLC), particularly those who have shown resistance to prior PD-(L)1 inhibitor treatments.

Insights from the Study

Professor Han Baohui from a renowned hospital shared the optimistic findings regarding cadonilimab combination therapy during the conference. Patients treated with this innovative therapy achieved impressive outcomes, including a 6-month progression-free survival (PFS) rate of 56.9% and a median PFS of 6.5 months. Moreover, the disease control rate peaked at 94.0%, indicating that nearly all participants experienced a degree of tumor control, underscoring cadonilimab's potential as a formidable second-line treatment option for this challenging cancer.

Clinical Study Overview

The clinical trial, known as the AK104-IIT-018 study, was conducted as a prospective, open-label, single-arm, multi-center Phase Ib/II study, exploring cadonilimab's effectiveness. This study, initiated in early 2023, focused on patients who had unresectable, incurable locally advanced or metastatic NSCLC. Participants had previously undergone treatment combining PD-1/L1 inhibitors with platinum-based chemotherapy, further complicating their treatment landscape.

Study Details and Patient Demographics

As of May 31, 2024, the trial included 46 patients, with a diverse representation of cancer types: 41.3% were diagnosed with non-squamous NSCLC, while 58.7% had squamous NSCLC. The expression levels of PD-L1 among the participants varied, with some revealing levels that fall below the typical threshold for effective treatment response.

Evaluating PFS and Tumor Response

The PFS was notably impressive, with maturity showing a robust response rate compared to standard treatments. With a median PFS of 6.5 months, cadonilimab outperformed docetaxel alone. Notably, the objective response rate (ORR) recorded at 30.3% also surpassed earlier rates observed in traditional therapies.

Safety Profile and Tolerability

Another major highlight of this study was the favorable safety profile associated with cadonilimab when used in conjunction with anlotinib and docetaxel. Most patients tolerated the treatment, and adverse effects were manageable, enhancing the therapy's attractiveness as a viable option for patients facing limited choices.

The Role of Cadonilimab in Future Cancer Treatment

For patients grappling with advanced, driver gene-negative NSCLC post-primary treatment, the options remain extremely limited. Current guidelines suggest single-agent chemotherapy, which, while established, results in relatively low response rates. In response to this gap, cadonilimab's dual-target approach may fill an important niche in treatment regimens for immune-resistant NSCLC.

Cutting-Edge Mechanisms of Cadonilimab

Cadonilimab is designed uniquely to promote immune normalization within the tumor microenvironment, making it a promising player in modern cancer therapies. Its innovative structure allows for greater accumulation in tumor tissues, increasing its effectiveness while minimizing adverse reactions.

Akeso's Commitment to Innovative Treatments

Akeso, Inc. (9926.HK) stands at the forefront of biopharmaceutical innovation, having established a comprehensive R&D system that nurtures the development of groundbreaking medical solutions. The company continues to evolve by focusing on several promising treatments, including cadonilimab, and has amassed a portfolio that reflects its commitment to addressing critical unmet medical needs.
