Brain Cancer


Glioblastoma multiforme (GBM) is the most common and aggressive of all primary brain cancer diagnosed in adults.

Worldwide in 2020, almost 300,00 people were diagnosed for the first time with brain cancer and in the same year 250,000 people died from their disease. Glioblastoma multiforme (GBM) is the most common and aggressive primary brain cancer diagnosed in adults, accounting for more than half of all brain cancers. The outlook for people diagnosed with GBM is poor, with half of all patients surviving between 12-18 months, 25% for more than 12 months, and only 5% surviving for five years. Telix’s brain cancer clinical program is focused on treatment with its TLX101 therapeutic candidate.




About TLX101

TLX101 (4-iodo-[131I]-phenylalanine or 131I-IPA) is a new investigational therapeutic radiopharmaceutical being developed to treat glioblastoma (GBM). TLX101 targets LAT-1, a promising target in several cancer types, including glioblastoma. TLX101 is a novel approach that is readily able to pass through the blood-brain barrier, the normal protective barrier that prevents many potential drug candidates from entering the brain.


Current development activity

The combination of TLX101 and external beam radiation is currently being studied in a Phase I/II clinical trial called IPAX-1. The trial is being conducted at several hospital locations across Europe and Australia.
