About Us
Our proprietary 211At platform technology and pipeline provides clinically meaningful efficacy, safety, and supply chain advantages.
The superior properties of 211At present best-in-class opportunities for alpha-emitting targeted radiotherapeutics. We are addressing a critical challenge in the development of effective and safe targeted radiotherapeutics by leveraging decades of our founders’ experience in radiopharmaceutical drug development and astatine research. This deep expertise combined with prominent investor support and a seasoned drug development team uniquely positions Z-Alpha as the global leader in 211At therapeutic development. Our technology is generating a robust pipeline of therapeutic programs to address high unmet medical needs across a variety of large market indications.
Our Technology
Among the differentiated characteristics of 211At, the production and decay chain present a viable solution to various existing challenges in targeted radiotherapy.
211At has the highest rate of deposition or energy release of all alpha emitting isotopes and is produced on demand from readily available natural bismuth and decays to stable 207Pb. Enabled by on-demand production and free from high-energy daughters or unwanted decay by-products, it offers a clean, well-defined decay profile.
The short half-life, favorable decay properties, and ability to image patients treated with 211At in real time provide opportunities for preferential dosing regimens and potential for earlier lines of treatment and combinations. When combined with our proprietary labeling and linker technologies, we can achieve rapid tumor targeting and expeditious excretion with multiple attractive targeting modalities in our pipeline.
