Optimizing the Entire System

A Decade of Deliberate, End-to-End Engineering

Built Over a Decade:

Q&A

Advancing a Theranostic Approach:

212Pb is Our Isotope of Choice

Choosing The Right Isotope

Kinetics Matter: 212Pb Hits Hard and Fast For Strong Activity with Less Systemic Exposure

𝜶-Particles Delivers More Potent, Targeted Tumor Killing vs. β-Particles

212Pb Further Enhanced by Proprietary Chelator for Targeted Delivery of Payload

212Pb Multi-Mechanistic Activity Drives Tumor Destruction and Anti-Tumor Immunity

Rationale for Synergy with Immune Checkpoint Inhibitors

212Pb Uniquely Suited for Combination with Immune Check Point Inhibitors

212Pb Half-life Is More Convenient for Customers




Advancing a Theranostic Approach:

Supply Chain and Manufacturing Infrastructure

End-to-End Manufacturing with Clinical Supply Secured and Commercial Scale Underway

Direct-to-Hospital Delivery through Integrated Isotope Production

Reliable, On-Demand 212Pb from 228Th and 224Ra

Flexible Scalable 224Ra Supply Enables Regional Manufacturing

Ideal for Regional Manufacturing

On-Demand Fulfillment at Regional Sites for Finished Product Delivery

Daily Production at Regional Sites Ensures Supply of Ready-to-administer Product

Reaching the Largest Addressable Market with Regional Manufacturing

Mature, Well-Established Distribution Networks
