Telix Pharmaceuticals' TLX101-Px New Drug Application Accepted by FDA
Telix Pharmaceuticals announces that the United States Food and Drug Administration has accepted the company's resubmitted New Drug Application for TLX101-Px, an investigational PET agent for the imaging of glioma, and has assigned a PDUFA goal date of September 11, 2026. The approval of TLX101-Px will fulfil a significant unmet medical need for the characterization of recurrent or progressive glioma from treatment related changes in both adult and pediatric patients. Neuroimaging of glioma with 18F-FET is already broadly recommended in international clinical practice guidelines - including NCCN Guidelines - and TLX101-Px has been granted Orphan Drug and Fast Track designations by the FDA. "There remains a critical unmet need in improving our ability to image residual glioma after treatment," said Thomas Hope, MD, Vice Chair, Department of Radiology and Biomedical Imaging, University of California, San Francisco. "We have worked with Telix for the last three years to help leverage our clinical data to help make FET-PET available to patients in the United States." Telix's FY 2026 financial guidance does not include any revenue contribution from TLX101-Px.
