Telix Pharmaceuticals to acquire ImaginAb assets to advance radiopharmaceutical development

Telix Pharmaceuticals Limited, a global leader in therapeutic and diagnostic radiopharmaceuticals, has announced a strategic acquisition of assets from ImaginAb, Inc., a clinical-stage biotechnology company. This bold move includes a pipeline of promising therapeutic candidates, a state-of-the-art biologics technology platform, and a California-based research facility. The acquisition is set to significantly enhance Telix’s ability to innovate in precision medicine, addressing unmet clinical needs in oncology and rare diseases.

The transaction, valued at up to $185 million, underscores Telix’s commitment to expanding its capabilities in next-generation radiopharmaceutical technology.

Pioneering Radiopharmaceutical Innovation with Targeted Biologics

Telix Pharmaceuticals’ acquisition introduces several high-value assets into its existing portfolio. These include drug candidates targeting molecules such as DLL3 and integrin αvβ6, as well as other novel targets in early discovery stages. These biologics utilize small engineered antibody formats designed for highly specific tumor targeting, facilitating rapid tumor uptake and clearance.

This advanced biologics platform allows the combination of precision imaging with therapeutic applications, particularly through radiopharmaceutical agents using alpha emitters. By integrating these assets, Telix aims to broaden its reach into disease areas with significant unmet medical needs.

Richard Valeix, Telix’s CEO of Therapeutics, emphasized that this acquisition brings a proprietary drug discovery platform, a robust theranostics pipeline, and a team of expert researchers, enhancing Telix’s ability to explore new disease areas.

Strategic Benefits of Acquiring ImaginAb’s Assets

The transaction includes a cutting-edge research facility in California, which is staffed by highly skilled professionals in protein engineering and radiopharmaceutical development. This facility is expected to play a pivotal role in strengthening Telix’s in-house research capabilities.

Additionally, ImaginAb’s patented imaging agents, such as its lead candidate CD8 ImmunoPET, bring clinical-stage assets that complement Telix’s portfolio. CD8 ImmunoPET is currently in Phase 2 trials and has been licensed to pharmaceutical companies for use in immunotherapy trials, primarily in oncology.

Dr. Anna M. Wu, co-founder of ImaginAb, highlighted the growing demand for radiopharmaceutical solutions that deliver precision while minimizing off-target radiation. She noted that Telix’s expertise in this area positions it as an ideal partner to maximize the potential of ImaginAb’s proprietary platform.

Key Financial and Operational Details

The total transaction is valued at $185 million (AU$299 million), with an upfront payment of $41 million in cash and equity. Deferred payments linked to key development and commercial milestones account for the remainder. The deal also includes royalties on net sales and sublicense fees on a limited number of platform products.

The equity portion of the payment will be issued under Telix’s placement capacity and is subject to voluntary escrow restrictions to ensure stability. Regulatory approvals and customary conditions must be satisfied before the transaction is finalized.

Market Impact and Future Outlook

Telix’s acquisition is expected to enhance its position as a leader in radiopharmaceuticals, a rapidly growing sector within oncology treatment. The integration of ImaginAb’s assets enables Telix to explore innovative approaches to cancer therapy, particularly in theranostics—an area combining therapy with diagnostics to improve treatment precision.

Industry analysts believe this acquisition will allow Telix to address increasing global demand for advanced diagnostic and therapeutic solutions. With ImaginAb’s biologics platform, Telix is poised to unlock new opportunities in immuno-oncology and beyond.

Telix’s flagship imaging product, Illuccix (68Ga PSMA-11), has already set a benchmark in prostate cancer diagnostics, having received regulatory approvals in the U.S., Canada, and Australia. This acquisition further positions Telix as a frontrunner in the development of next-generation radiopharmaceuticals aimed at both common and rare diseases.

Expert Perspectives on the Radiopharmaceutical Sector

The radiopharmaceutical industry is witnessing significant momentum, with innovations like precision-targeted biologics transforming oncology treatment. Experts in the field highlight the growing role of antibody-based radiopharmaceuticals in improving patient outcomes.

Telix’s integration of ImaginAb’s platform aligns with broader industry trends emphasizing precision medicine and targeted therapies. With these advanced capabilities, Telix is expected to push the boundaries of radiopharmaceutical innovation, making a meaningful impact on global healthcare.

By acquiring ImaginAb’s cutting-edge biologics platform and research capabilities, Telix Pharmaceuticals demonstrates its commitment to advancing precision medicine, delivering innovative solutions in oncology and beyond. This transaction solidifies Telix’s position at the forefront of radiopharmaceutical innovation.
