What else do investors need to know?

ProstACT Global is the first Phase 3 trial to test a PSMA-targeted radio antibody drug combined with standard-of-care therapies versus standard-of-care alone for metastatic castration-resistant prostate cancer. The global rollout is accelerating, with applications underway to expand into European sites.

The company highlights potential patient benefits, including different targeting and fewer side effects such as kidney toxicity and dry mouth compared to current radioligand therapies. The clinical trial's expansion signals Telix's growing international ambition, including approaching both US and European regulators for further approvals.

What did Telix Pharmaceuticals management say?

Dr. David N. Cade, Group Chief Medical Officer, said:

Dosing the first patient into Part 2 of the randomized treatment expansion of ProstACT Global trial is a significant milestone for Telix's late-stage prostate cancer therapeutics pipeline. We look forward to presenting the preliminary data from Part 1 of the study to the FDA and EMA in the coming months.

What's next for Telix Pharmaceuticals?

Telix plans to submit Part 1 data to the FDA to enable US site participation in the clinical trial and expects to share preliminary results publicly in line with its regulatory strategy. In parallel, the company is seeking further expansion into Europe and other international markets.

With global recruitment underway and regulatory milestones ahead, Telix aims to strengthen its late-stage oncology pipeline and broaden its impact for patients with advanced prostate cancer.
