CD8+ T-cell PET/CT Imaging in COVID-19 Patients (Tangelo)

Netherlands
  • Radboud University Medical Center
A subset of patients diagnosed with severe acute respiratory syndrome (SARS)-CoV2 infection present with lymphopenia. The degree of lymphopenia, and in particular reduced cluster of differentiation (CD)8+ T-cell numbers, is correlated with clinical deterioration and intensive care unit (ICU) admission. The underlying reasons for lymphopenia in coronavirus disease (COVID)-19 is currently unclear, We aim to assess differences in the in vivo distribution of CD8+ T-cells in patients with proven SARS-CoV2 presenting with lymphopenia or with normal lymphocyte counts, using Zirconium-89 ([89Zr])Df-IAB22M2C positron emission tomography (PET) imaging.

ASP8374 + Cemiplimab in Recurrent Glioma

United States
  • Brigham and Women's Hospital
This study is looking at the safety and efficacy of the drug combination of ASP8374 with cemiplimab in people with recurrent malignant glioma. The study will be conducted in two parts, the first portion of the study will be to establish the highest dose of ASP8374 that can be given safely with cemiplimab and will be used as the recommended dose of ASP8374 in combination with cemiplimab for the second portion of the study. The second portion of the study will be to compare the effect of having ASP8374 in combination with cemiplimab prior to surgery. The names of the study drugs involved in this study are: ASP8374; Cemiplimab; 89Zr-Df-IAB22M2C (Administered as part of scan procedure)

Protocol IAB-CD8-201 is a Phase II, Open Label, Multi-Dose Study of ⁸⁹Zr-Df-IAB22M2C (CD8 PET Tracer) for Positron Emission Tomography (PET/CT) in Patients with Advanced or Metastatic Melanoma, Non-Small Cell Lung Cancer, Renal Cell Carcinoma, Squamous Cell Carcinoma of the Head and Neck Selected to Receive Standard-of-Care Immunotherapy as Single Agent or in Combination. This study will evaluate the safety of repeat doses of ⁸⁹Zr-Df-IAB22M2C, assess and quantify any detectable changes in ⁸⁹Zr-Df-IAB22M2C uptake from Baseline to post-Treatment, establish the relationship of ⁸⁹Zr-Df-IAB22M2C uptake in tumors with CD8+ TIL density, biodistribution, evaluate the variance in participants' gene expression pre- and post-Treatment, evaluate the correlation of ⁸⁹Zr-Df-IAB22M2C uptake with clinical response by RECIST 1.1/iRECIST and evaluate the correlation of ⁸⁹Zr-Df-IAB22M2C uptake with immune infiltrates and other molecular biomarkers (CD4, CD8, PD-1 and PD-L1) expression by IHC.
