Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety of repeat doses ⁸⁹Zr-Df-IAB22M2C and to establish the relationship between ⁸⁹Zr-Df-IAB22M2C PET/CT lesion uptake with CD8+ cells by immunohistochemical staining in patients with selected advanced and metastatic solid malignancies who are scheduled to receive standard of care immunotherapy. The study will also evaluate uptake of ⁸⁹Zr-Df-IAB22M2C by PET/CT in patients at baseline and on immunotherapy.

| Phase 2 |
Detailed Description
After being informed about the study and potential risks, all patients giving written informed consent will be evaluated to determine eligibility for study entry. Up to 1 week prior to initiation of immunotherapy, patients will receive an injection of ⁸⁹Zr-Df-IAB22M2C (1.0 mCi) and will undergo PET/CT scanning to determine baseline uptake of ⁸⁹Zr-Df-IAB22M2C in tumor lesions and reference tissues. Patients will receive an additional injection of ⁸⁹Zr-Df-IAB22M2C (1.0 mCi) and PET/CT scan 4-6 weeks after starting immunotherapy (on-therapy) to evaluate uptake of ⁸⁹Zr-Df-IAB22M2C in tumor lesions and reference tissues, and to assess potential changes in uptake of ⁸⁹Zr-Df-IAB22M2C compared to the baseline scan.
