Frequently asked questions about TLX101

What is TLX101 used for?

TLX101 is being developed for the treatment of recurrent glioblastoma, an aggressive form of brain cancer. It is under investigation in a Phase 3 clinical trial in adults with this condition. The trial evaluates TLX101-Tx plus standard of care compared with standard of care alone.

What does TLX101 target?

TLX101 targets PSMA, or prostate-specific membrane antigen. It is a small molecule designed to interact with this molecular target as part of its therapeutic approach in oncology. The targeting of PSMA is the basis for its investigation in neoplastic disease, including glioblastoma.

Who is developing TLX101?

TLX101 is being developed by Telix Pharmaceuticals Limited, which trades under the ticker TLX. The company is responsible for the clinical development of this small molecule oncology asset.

What phase is TLX101 in?

TLX101 is in Phase 3 clinical development. The ongoing trial is a Phase 3 study, and the drug is investigational and has not been approved by the FDA. It is being evaluated in patients with recurrent glioblastoma.

What clinical trials is TLX101 in?

TLX101 is being studied in the Phase 3 trial NCT07100730, titled Study of TLX101-Tx Plus Standard of Care (SoC) Versus SoC Alone for the Treatment of Patients With Recurrent Glioblastoma. The trial is currently recruiting and plans to enroll 50 participants across Australia, Austria, Belgium, and the Netherlands.
