TAIPEI\u00a0and\u00a0SAN DIEGO<\/span>, Dec. 29, 2025<\/span><\/span> \/PRNewswire\/ — Following its recent clinical collaboration with the multinational pharmaceutical company BeOne Medicines to explore combination therapy with its marketed PD-1 inhibitor in the challenging field of cold tumor treatment, Senhwa Biosciences, Inc. (TPEx: 6492, hereafter “Senhwa”), today announced another major milestone. The Company’s first-in-class investigational drug Pidnarulex (CX-5461) will be evaluated in combination with the globally recognized antibody-drug conjugate (ADC), Trastuzumab Deruxtecan (Enhertu\u00ae), in a Phase 1b<\/span> clinical trial. The study is designed for HER2-positive solid tumors and breast cancer patients, including those with HER2-low expression and metastatic breast cancer. Supported by the U.S. National Cancer Institute’s (NCI) NExT program, which funds multiple CX-5461 studies including combination strategies, Senhwa is positioning itself at the forefront of one of the most promising areas in oncology therapeutics, and this milestone marks CX-5461’s entry into the fast-growing ADC market.<\/p>\n

\n<\/div>\n

World’s First G4 Stabilizer Meets Leading ADC<\/b><\/p>\n

CX-5461 is the world’s first and most advanced G-quadruplex (G4) stabilizer<\/b> in development. It has shown promising activity in early-phase trials for breast cancer and other solid tumors in study sponsored by SU2C-CCTG in Canada<\/span>. Its combination with Enhertu\u00ae is expected to enhance treatment efficacy in HER2-low patients and offer new therapeutic possibilities.<\/p>\n

Enhertu\u00ae, co-developed by AstraZeneca and Daiichi Sankyo, is the first HER2-directed ADC approved for HER2-low and HER2-ultralow metastatic breast cancer<\/b>. This innovative drug uses a monoclonal antibody to precisely target tumor cells and deliver the chemotherapy payload Deruxtecan<\/b> directly into the tumor, enabling highly effective cancer cell killing while minimizing harm to healthy cells.<\/p>\n

Entering a High-Growth Market<\/b><\/p>\n

The global ADC market is projected to grow at a CAGR of 28.4%<\/b>, reaching approximately USD 47 billion<\/span> by 2029<\/b>. Analysts believe that Senhwa’s clinical development strategy combining CX-5461 and Enhertu\u00ae positions the company to directly tap into this high-growth and highly competitive oncology market.<\/p>\n

Differentiated Advantage and Strategic Collaboration Potential<\/b><\/p>\n

Although existing HER2-targeted therapies have transformed the treatment landscape for breast and gastric cancers, their efficacy in HER2-low solid tumors remains limited. Experts suggest that if CX-5461’s novel mechanism of action, when combined with ADC’s precise delivery platform, proves effective, it could break through current treatment barriers, expand indications to additional tumor types, and establish a clear competitive edge.<\/p>\n

With global pharmaceutical companies racing into the ADC space, collaborations and licensing agreements have become mainstream. Should Senhwa’s combination therapy demonstrate strong clinical efficacy, it could attract strategic partnerships with major international pharma players, bringing in substantial licensing revenues and long-term collaboration opportunities.<\/p>\n

Driving Long-Term Value Creation<\/b><\/p>\n

Analysts further note that the successful advancement of this trial would significantly enhance Senhwa’s international visibility in oncology, elevate the company’s market valuation, and deliver sustainable long-term returns for investors and shareholders.<\/p>\n

HER2 has been validated as a critical oncogenic driver across multiple tumor types. By leveraging the innovative combination of CX-5461 and Enhertu\u00ae, Senhwa aims to pioneer breakthrough therapies, capture a substantial share of the rapidly growing ADC market, and build a diverse oncology treatment platform. The company reiterated its commitment to strengthening its R&D pipeline, integrating next-generation ADC technologies with its proprietary drug candidates, and advancing toward its vision of becoming a leading Asia<\/span>-based oncology innovator with a global footprint.<\/p>\n
