Building the Most Comprehensive Her2 Brest Cancer Biosimialar Pipleline
Driven by global patient needs, EirGenix is progressively constructing the industry's most competitive HER2 biosimilar matrix. Our development strategy comprehensively covers the different treatment stages of breast cancer patients. The pipeline encompasses classic targeted therapies Trastuzumab and Pertuzumab, innovative subcutaneous combination formulations that significantly improve convenience of administration, and extends all the way to next-generation Antibody-Drug Conjugate (ADC) biosimilars, providing the clinical setting with more comprehensive and continuous therapeutic options.

The Global R&D Milestone of EG12014
Balancing R&D innovation with stable operations, EirGenix's first launched flagship product is EG12014, a Trastuzumab biosimilar for the treatment of breast cancer. EG12014 has successfully completed global clinical trials, and the data confirms its high bioequivalence to Herceptin® produced by the originator Roche, making EirGenix the first biotechnology company in Taiwan to complete Phase III clinical trials for a biosimilar in Europe. We are committed to pushing it onto the international stage, providing patients with a new treatment option that features both top-tier quality and affordability.
Concurrently, we have launched a deep layout for breast cancer indications, including Pertuzumab EG1206A, another HER2 targeted drug with a different mechanism of action, implementing efficient product lifecycle managemen.
Targeting ADC and Immuno-Combination Therapies to Breakthrough Tumor Drug Resistance
Faced  with the challenges of clinical drug resistance, combination therapy has become a global biomedical trend. EirGenix precisely targets the combination potential of ADC biosimilars with immune checkpoint inhibitors (such as Atezolizumab) or specific targeted drugs (such as Daratumumab).
In addition to accelerating the R&D of ADC biosimilars, we have proactively mapped out key immuno-oncology biologics that are about to face patent cliffs. By positioning ourselves ahead of time for these key drugs with high medical needs, EirGenix will continue to deepen its international market competitiveness in the field of cancer treatment.
