Telix to Acquire Next-Generation Therapeutic Assets and Innovative Biologics Technology Platform

MELBOURNE, Australia and INDIANAPOLIS, Jan. 13, 2025 /PRNewswire/ -- Telix Pharmaceuticals Limited (ASX: TLX, Nasdaq: TLX, Telix, the Company) today announces it has entered into an asset purchase agreement with antibody engineering company ImaginAb, Inc. (ImaginAb) to acquire a pipeline of next-generation therapeutic candidates, proprietary novel biologics technology platform, and a protein engineering and discovery research facility to enhance existing innovation capabilities.

This transaction adds a pipeline of early-stage drug candidates against high-value targets including DLL3^[1] and integrin αvβ6^[2], as well as several other novel targets in discovery stage. These next generation drug candidates fit synergistically with Telix's therapeutics pipeline, enabling expansion to future therapy areas with unmet clinical need. The acquired intellectual property utilizes small engineered antibody formats that enable highly specific cancer targeting, combined with fast tumor uptake and blood clearance. This technology has the potential to be highly effective for imaging and treating tumors with a broad range of radioisotopes, with alpha emitters of particular interest.

The transaction also includes a state-of-the-art research facility in California, staffed by a talented team of discovery, protein engineering and radiopharmaceutical development experts. Together, these assets will provide Telix with further in-house capabilities in antibody engineering and preclinical development, as well as a novel biologics platform to create the next generation of Telix precision medicine and therapeutic products, beyond the current clinical-stage pipeline. 

Richard Valeix, Chief Executive Officer, Therapeutics, Telix, said, "The combination of a proprietary drug discovery platform, pipeline of promising theranostic assets and a talented team of subject matter experts will enhance Telix's research and innovation capability now and into the future. This acquisition will enable Telix to explore new disease areas with state-of-the-art radiotherapeutic technology."

Dr. Anna M. Wu, Co-Founder and Board Member, ImaginAb, added, "As the radiopharmaceutical sector gains momentum there is a significant need for targeting agents to be more selective, deliver less off-target radiation, and better match the pharmacology and radiobiology of a given radionuclide. The team's deep expertise in antibody engineering and the resulting development of a valuable, proprietary platform technology has led to clinical proof-of-concept. Telix is the right partner to unlock the future therapeutic potential of this platform."

Transaction details

Telix will acquire these assets through an asset purchase agreement with a concurrent technology license agreement to be signed at closing. The purchase price for the transaction is US$45 million (AU$73 million)^[3], comprised of US$10 million in cash and US$31 million in equity at closing, and a deferred payment of up to US$4 million in equity at the conclusion of a 15-month indemnity period.

Upon achievement of specific key development and commercial milestones, Telix will pay up to a total of US$185 million (AU$299 million), a portion of which may be paid in cash or equity at Telix's election^[4]. Royalties are also payable on net sales in the low single digits on a limited number of platform and early-stage products after the first four products have been developed, as well as single-digit sublicense fees, as applicable. 

Telix will issue ordinary shares to ImaginAb within its Listing Rule 7.1 placement capacity as consideration for the acquisition. Upfront equity consideration will be subject to voluntary escrow (lock-up/leak-out) restrictions with equal tranches being released from escrow 60, 90 and 120 days after closing. Completion of the transaction is subject to customary conditions, including regulatory approvals and other third-party consents.
