Study Overview
Brief Summary
The study is a phase 2, non-comparative and non-randomized, single arm, national clinical trial testing the hypothesis that CAIX-PET has diagnostic and theranostic potential in VHL disease and in VHL-/- tumors. Participants will receive a single dose of the diagnostic radiopharmaceutical [89Zr]Zr-DFO-Girentuximab and subsequently will be subjected to imaging with an hybrid PET/CT scanner. Sensitivity and diagnostic accuracy of experimental imaging will be assessed against standard of truth derived from standard of care procedures such as MRI or pathology following surgery. A theranostic approach will be simulated by replacing the physical decay of the diagnostic isotope [89Zr]Zr with the physical decay of therapeutic isotopes and evaluating tissue dosimetry.

- •For females of reproductive potential, negative pregnancy test and use of highly effective contraception for 30 days following IMP administration
- •For males of reproductive potential, use of highly effective contraception for 30 days following IMP administration.
- •And, for the primary cohort:
- •Diagnosis of VHL disease requiring surveillance following confirmation of pathogenic variant at genetic test
- •Alternatively, for the secondary cohort:

- •Exposure to any murine or chimeric antibodies within 5 years prior to the planned IMP administration
- •Exposure to any experimental diagnostic or therapeutic drug within 30 days from the planned IMP administration
- •Surgery, biopsy, ablative procedure, radiotherapy or any other local treatment for any primary tumor within 4 weeks prior to the planned IMP administration
- •Exposure to any systemic agent within 4 weeks prior to the planned IMP administration or in case of continuing adverse effects with grade >1 from such therapy
- •Current exposure to systemic agents or scheduled therapy in the next 6 months following the planned IMP administration
- •Serious non-malignant disease (e.g. psychiatric, infectious, autoimmune or metabolic) that may interfere with the objectives of the study or within the safety of compliance of the subjects as judged by the Investigator
- •Known hypersensitivity to [89Zr]Zr-DFO-Girentuximab or DFO (Desferrioxamine)
- •Severe chronic kidney disease with glomerular filtration rate ≤ 30 mL/min/1.73m2
