Telix Completes Acquisition of FAP-targeting Theranostic Candidates
Melbourne (Australia) and Indianapolis, IN (U.S.A.) – 12 March 2025. Telix Pharmaceuticals Limited (ASX: TLX, Nasdaq: TLX, Telix, the Company) today announces that it has completed the transaction to expand its theranostic pipeline with new candidates targeting Fibroblast Activation Protein (FAP), one of the most promising pan-cancer targets in nuclear medicine.
In November 2024, Telix announced that it had entered into asset purchase and exclusive worldwide in-license agreements for a suite of clinically validated FAP-targeting therapeutic and precision medicine (diagnostic) radiopharmaceutical candidates, developed by Professor Frank Rösch and his collaborators at the Institute of Nuclear Chemistry at the Johannes Gutenberg-Universität Mainz, Germany.
Telix has added the lead FAP-targeting therapeutic compound to its pipeline under the name TLX400 and is building out a theranostic development program in bladder cancer, as part of the Company’s urology focus, as well as exploring its potential as a pan-cancer therapeutic across multiple indications in solid tumors.
FAP is a pan-cancer marker expressed in the tumor microenvironment of epithelial cancers and on the surface of some specific cancer types, including sarcomas and mesotheliomas. The next-generation assets that Telix has acquired are differentiated by a novel structure that drives extended tumor retention while minimizing off-target uptake, potentially overcoming the limitations seen with first-generation compounds. The diagnostic and therapeutic compounds have been clinically validated in over 500 patients across a variety of solid tumors and are the subject of multiple peer-review publications1.
Telix’s Chief Executive Officer, Therapeutics, Richard Valeix, said, “We are pleased to have finalized this transaction so that we can continue to leverage the FAP-targeting research pioneered by Professor Rösch and his team. We believe this technology holds great promise for both imaging and treating tumors, and Telix is now focused on using these compounds to build out our urology franchise and explore pan-cancer opportunities, with the goal of bringing new theranostic solutions to physicians and their patients.”
Deal terms and conditions
At closing, Telix paid €5.3 million in cash (in addition to €700,000 paid upfront at agreement signing); and will pay a further €4.0 million over the next 12 months subject to potential indemnity setoff, under an exclusive worldwide license agreement with a German company where Professor Rösch is CEO, SCV GmbH, and a concurrently-signed asset purchase agreement with German company Medianezia GmbH, which parties collectively hold the intellectual property rights to the FAP-targeting assets. Telix will pay up to a further €132 million contingent upon achievement of certain clinical development and regulatory milestones related to both the diagnostic and therapeutic candidates under both agreements. An additional €20 million will be payable under the license agreement on achievement of certain commercial milestones related to the diagnostic product; as well as royalties on net sales in the low to mid-single digits on the diagnostic product and an earlier formulation of the therapeutic product, if used.
