Phase I Trial: 68Ga-NODAGA-E(c[RGDyK])2 Positron Emission Tomography for Imaging Angiogenesis in Primary and Metastatic Tumor Lesions in Humans

Study Overview
=================
Brief Summary
-----------------
The primary objective of the trial is to test the new radio tracer 68Ga-NODAGA-E[c(RGDyK)]2 for PET imaging of angiogenesis. The tracer has the potential of identifying tumors with a high level of angiogenesis, which is one of the cancer hallmarks. Furthermore, the tracer can potentially be used in early response assessment to anti-angiogenic treatment. This is a first-in-man study to test the radio tracer in cancer patients. Safety, biodistribution and dosimetry will be evaluated by repeated PET imaging (10 minutes, 1 hour and 2 hours post injection).

Safety, biodistribution and dosimetry will be evaluated by repeated PET imaging (10 minutes, 1 hour and 2 hours post injection). The primary end points are safety, biodistribution and dosimetry of 68Ga-NODAGA-E[c(RGDyK)]2. In addition, the quantitative uptake of 68Ga-NODAGA-E[c(RGDyK)]2 will be compared to the expression of integrin αvβ3 measured directly in tumor tissue obtained by surgery or biopsies. The study will be monitored and evaluated in accordance with the principles of Good Clinical Practice (GCP).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Biodistribution | Change in biodistribution estimated by PET | 2 hours | 
| Dosimetry | Dosimetry will be calculated with the use of OLINDA/EXM software (mSv) based on repeated PET imaging with the radiotracer 68Ga-NODAGA-E(c[RGDyK])2. | 2 hours | 
| Safety of 68Ga-NODAGA-E(c[RGDyK])2 PET as measured by the number of participants with adverse events and significant changes in vital signs, electrocardiogram, and laboratory data. |  | 48 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quantitative uptake of the radiotracer 68Ga-NODAGA-E(c[RGDyK])2 in tumor tissue | The patients will be PET scanned 10 minutes, 1 hour and 2 hours post injection of the radiotracer 68Ga-NODAGA-E(c[RGDyK])2. These timepoints will be used for assessment of tumor uptake by the use of maximum and mean standardized uptake value (SUV). | 2 hours |
