Hansel Comas-Rojas, staff radiochemist in the ART Lab, brought a new tracer to the field’s biggest stage this year. At the American Association for Cancer Research (AACR) 2026 Annual Meeting, he presented “Pilot [89Zr]Zr-LNTH-2403 PET Imaging in Healthy Non-Human Primates: Assessing Biodistribution, Dosimetry, Pharmacokinetics, and Safety.”

In partnership with Lantheus , the study follows [89Zr]Zr-LNTH-2403 through its first imaging evaluation in non-human primates. These are the questions that have to be answered before a tracer can move toward the clinic, and the data mark an early but important milestone on that path.

With tens of thousands of researchers and clinicians in attendance, AACR is one of the largest cancer research meetings in the world, and a strong showing for Hansel and the lab.
