ImmunoPET: harnessing antibodies for imaging immune cells

Anna M. Wu et al.

Summary: Immunotherapy for cancer has made dramatic progress but faces challenges in diagnosis, driving the need for innovative non-invasive imaging approaches. ImmunoPET, utilizing antibodies, shows promise in detecting immune cell subsets, biomarkers, and tracking cellular therapeutics in preclinical models. Advances in radionuclide availability and biopharmaceutical manufacturing infrastructure have accelerated the clinical translation of ImmunoPET, which is poised to provide key information on prognosis and monitoring immune responses to therapy in cancer and beyond.

ImmunoPET: Antibody-Based PET Imaging in Solid Tumors

Reyhaneh Manafi-Farid et al.

Summary: Immuno-positron emission tomography (immunoPET) is a molecular imaging technique that combines the high sensitivity of PET with the targeted ability of monoclonal antibodies. While various radioimmunotracers have been developed, only a few have been translated into clinical practice due to issues such as slow kinetics, high physiological uptake, and heterogeneous activity. Efforts are being made to overcome these limitations and develop new tracers.

Preclinical Evaluation of 99mTc-ZHER2:41071, a Second-Generation Affibody-Based HER2-Visualizing Imaging Probe with a Low Renal Uptake

Maryam Oroujeni et al.

Summary: The study prepared and characterized a second-generation affibody molecule ZHER2:41071 with an improved scaffold, showing promising imaging properties for HER2 expression in tumors. Compared to the first-generation affibody molecules, ZHER2:41071 demonstrated lower renal uptake and similar uptake in tumors and kidneys. The new probe [Tc-99m]Tc-ZHER2:41071 provided the best tumor-to-blood ratio for single photon emission computed tomography (SPECT) among HER2-imaging probes described in the literature so far, making it a promising candidate for further clinical translation studies.

Nanobodies for Medical Imaging: About Ready for Prime Time?

Lea Berland et al.

Summary: Recent advances in medical treatments, particularly for cancer patients, have significantly increased life expectancies for many patients with advanced or metastatic cancers. However, challenges remain for patients who do not respond well to treatments or experience toxic side effects. Studying cellular and molecular mechanisms underlying variable treatment responses is crucial for developing more effective therapeutics. Non-invasive imaging techniques, such as immuno-PET with nanobodies, offer promising opportunities for precise targeting and whole-body information.

Inverse electron demand Diels-Alder click chemistry for pretargeted PET imaging and radioimmunotherapy

Samantha M. Sarrett et al.

Summary: This approach utilizes the rapid, bio-orthogonal inverse electron demand Diels-Alder reaction between a radiolabeled tetrazine and a trans-cyclooctene-bearing antibody for pretargeted positron emission tomography imaging and endoradiotherapy. By labeling the antibody after it has reached its target, this method reduces radiation doses to healthy tissues while achieving high activity concentrations in target tissues. Proper training in radiation safety and the handling of laboratory mice is crucial for the successful implementation of this protocol.

Potential and pitfalls of 89Zr-immuno-PET to assess target status: 89Zr-trastuzumab as an example

Marc C. Huisman et al.

Summary: The study investigated the relationship between antibody tumor uptake and target concentration using mathematical modeling of Zr-89-labeled antibody disposition, with trastuzumab kinetics serving as an example. Results showed that Zr-89-trastuzumab uptake initially increases with increasing target concentration before leveling off, influenced by the total administered mass dose of the antibody. The findings suggest the potential of Zr-89-trastuzumab uptake in assessing target expression, while also highlighting the importance of defining clinical target positivity and considering the administered mass dose to avoid false-positive results.
