Q1 2026 Revenue (Unaudited)
Executive Commentary
Dr. Christian Behrenbruch, Managing Director and Group CEO, stated, “Growth accelerated across our Precision Medicine business in the first quarter, with U.S. dose volumes increasing 5% quarter-over-quarter. This performance reflects the growing uptake of Gozellix alongside Illuccix, contributing to market share gains underpinned by disciplined sales execution and pricing, and high-quality service delivery despite extreme North American weather conditions, an advantage of the pharmacy distribution model. With our two‑product PSMA[9] imaging strategy, differentiated clinical positioning and expanding commercial presence globally, we are seeing a solid foundation for continued growth through 2026. Importantly, we are delivering on our strategic priorities to advance our high-value clinical programs, demonstrated by the momentum in our therapeutics pipeline this quarter.”
Therapeutics Business Unit
Telix continues to progress its industry-leading Therapeutics pipeline, which spans multiple product candidates and disease areas. Q1 2026 highlights include:
- TLX591-Tx (lutetium (177Lu) rosopatamab tetraxetan): Part 1 of ProstACT Global, the Phase 3 trial of its lead prostate cancer therapy candidate, achieved its study objectives, demonstrating an acceptable safety and tolerability profile with no new safety signals observed1. No adverse drug-drug interactions were observed in TLX591-Tx combinations, demonstrating the feasibility of integrating TLX591-Tx with current standard of care therapies for mCRPC[10], including ARPIs[11] (enzalutamide or abiraterone) and docetaxel. Telix has commenced engagement with the FDA to present data from Part 1 and ascertain eligibility for U.S. patients to participate in Part 2 (randomized treatment expansion). Part 2 is open for enrollment in Australia, New Zealand and Canada, with site activation underway in preparation to open enrollment in China, Singapore, South Korea, Türkiye, the United Kingdom and Japan, where regulatory approvals have already been granted.
- TLX101-Tx (131I-iodofalan): Telix has enrolled the first patient in IPAX-BrIGHT, an international, multi-center pivotal trial of TLX101-Tx in patients with recurrent glioblastoma[14]. The trial is now open for enrollment in Australia, Austria and the Netherlands and has received regulatory approval to commence in Belgium.
- TLX090-Tx (153Sm-DOTMP): Telix continues to dose patients in SOLACE[15], a Phase 1 study of a drug candidate for treating pain in patients with osteoblastic bone metastases from prostate and breast cancers. The study was expanded this quarter to include additional U.S. sites to accelerate recruitment.
- TLX597-Tx (177Lu-DOTA-HYNIC-panPSMA): TLX597-Tx is a “next generation” PSMA-targeting prostate cancer therapy candidate being developed to facilitate patient access in select geographies, where routine clinical availability to approved therapies is limited or not available. Early clinical data suggests a favorable asset biodistribution with limited uptake in healthy organs of concern (e.g., salivary glands, kidneys) relative to available 177Lu-PSMA therapies. Interim data from OPTIMAL-PSMA[16], an investigator-led, randomized, dose intensification study of TLX597-Tx in mCRPC, will be presented at the International Prostate Cancer Symposium in April 2026.
Precision Medicine Business Unit
PSMA imaging portfolio:
- Telix continues to expand its commercial footprint with Illuccix now launched in 21 countries globally, which includes 16 countries in Europe. This growing international presence enhances access to PSMA-PET/CT imaging[17] while establishing a scalable commercial and operational platform to support future product launches, including follow-on therapeutic products.
- Telix’s broad proposed label for TLX591-Px (Illuccix) is under review by the NMPA Centre for Drug Evaluation as part of the NDA submission[18].
TLX101-Px, (Floretyrosine F 18 or 18F-FET):
- Telix has resubmitted its NDA in the U.S. with the additional clinical data and analysis as agreed with the FDA.
- Telix has submitted a MAA in Europe covering commercially significant markets, seeking to expand patient access to advanced brain imaging.
Zircaix®3 (TLX250-Px, 89Zr-DFO-girentuximab):
- Based on two successful Type A meetings with the FDA, Telix believes it has aligned on key outstanding issues for the Biologics License Application (BLA) resubmission, including demonstration of drug product comparability between clinical trial material and scale-up commercial production. The Company is now completing the agreed deliverables and documentation required, targeting a H1 submission.
Corporate Updates
Telix has announced the appointment of David Gill as Non-Executive Director (NED), effective May 11, 2026, as part of its Board renewal process[19]. Mr. Gill is expected to be appointed as Chair in due course, succeeding Dr. Mark Nelson who will remain on the Board as NED. The Board believes Mr. Gill’s appointment will enhance the Board’s capability, with extensive experience in U.S. public company governance, financial oversight and senior leadership across commercial and clinical-stage biopharmaceutical companies.
