Pidnarulex (CX-5461) – Enhertu combo to be evaluated in Ph 1b trial in HER2-positive and HER2-low solid tumors and breast cancer patients

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. 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®), in a Phase 1b 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.
