Onco IX (PHC-102) is a 99mTc labelled small molecule radiotracer for the non-invasive detection of carbonic anhydrase IX (CAIX) expressing solid tumors. The product consists of (i) a CAIX ligand derived from acetazolamide, (ii) a non-cleavable spacer and (iii) a peptide 99mTC chelator.
CAIX is a validated target, which is expressed in the majority of Renal Cell Carcinoma (RCC) patients, but also in a proportion of patients with other malignancies (e.g., ~30% of patients with Colorectal Carcinoma).
In preclinical studies, PHC-102 demonstrated high tumor uptake and excellent tumor-to-kidney ratios (i.e., 3:1 already 6 hours after intravenous administration).
The favorable tumor uptake and biodistribution of Onco IX has been validated by the successful imaging of primary and secondary RCC tumors in human patients.
