HUTCHMED Completes Phase II Study Enrollment for Fanregratinib

HUTCHMED Completes Phase II Study Enrollment for Fanregratinib

In an exciting development for cancer treatment, HUTCHMED (China) Limited has announced the completion of patient enrollment for its Phase II trial of fanregratinib (HMPL-453). This innovative therapy targets patients suffering from intrahepatic cholangiocarcinoma (IHCC) with specific genetic markers.

Study Overview

This study is designed as a single-arm, multi-center, open-label registration trial assessing the efficacy, safety, and pharmacokinetics of fanregratinib. It focuses on patients with biomarkers indicative of fibroblast growth factor receptor (FGFR)2 fusion/rearrangement, a known contributing factor to tumor progression.

Primary and Secondary Endpoints

The primary endpoint emphasized in this study is the objective response rate (ORR). Secondary endpoints include progression-free survival (PFS), disease control rate (DCR), duration of response (DoR), and overall survival (OS). A total of 87 patients have been enrolled to contribute to these vital measures.

Progress and Expectations

Following the first patient’s treatment in early 2023, HUTCHMED anticipates announcing topline results by late 2025. Positive outcomes from this study could catalyze a New Drug Application submission to China’s National Medical Products Administration (NMPA), opening doors for broader patient access to fanregratinib.

About Fanregratinib

Fanregratinib (HMPL-453) is a groundbreaking therapy that acts as a selective inhibitor for FGFR 1, 2, and 3. These receptors play a crucial role in tumor growth and the development of resistance to existing therapies. With abnormal FGFR signaling linked to the proliferation of cancerous cells, fanregratinib aims to disrupt this process effectively.

Understanding IHCC and FGFR2 Fusion/Rearrangement

Intrahepatic cholangiocarcinoma presents a significant challenge in oncology. Identified as a subtype of primary bile duct cancer, it had an estimated 61,900 new cases diagnosed within recent assessment years. Moreover, the growth rate of IHCC cases highlights the pressing need for effective treatment options.

Prevalence and Challenges

FGFR2 fusion or rearrangement has a prevalence rate of approximately 10-15% in IHCC patients, marking a critical area for targeted therapies like fanregratinib. Addressing this unique molecular characteristic is essential for developing personalized treatment strategies.

About HUTCHMED

HUTCHMED stands at the forefront of biopharmaceutical innovation as a commercial-stage company dedicated to discovering and developing targeted therapies and immunotherapies. Their commitment lies in enhancing treatment pathways for cancer and various immunological disorders. To date, HUTCHMED has transitioned multiple drug candidates from discovery into patient care, with their first medicines already making an impact in markets worldwide.

For involvement in impactful cancer research, HUTCHMED retains all global rights to fanregratinib, emphasizing their strategic positioning in this therapeutic sector.
