Solid Tumor, Adult
Conditions
Brief summary
This is a single arm study to evaluate the safety and biodistribution of 177Lu-labeled anti-ED-B mAbs SPECT imaging in patients with ED-B positive solid tumors.
Detailed description
After being fully informed about the study and potential risks, all patients giving written informed consent will be evaluated to determine eligibility for study entry. Patients will receive an injection of 177Lu-labeled anti-ED-B mAbs and will undergo SPECT/CT scanning to determine uptake of 177Lu-labeled anti-ED-B mAbs in tumor lesions and normal tissues and organs.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of tissue distribution of 177Lu-Anti-ED-B mAbs(B5-IgG4) | 1 year | Biodistribution of 177Lu-Anti-ED-B mAbs(B5-IgG4) evaluated by radioactive uptake values (standardized uptake values, SUVs) in various organs during repeated 177Lu-SPECT scans will be reported. |
| Dosimetry estimates of 177Lu-Anti-ED-B mAbs(B5-IgG4) | 1 year | Absorbed dose (radioactive uptake) estimates for different organs and tissues calculated with the AUCs and the OLINDA/EXM dosimetry program will be obtained and reported. |
| Incidence of Treatment-Emergent Adverse Events | 1 year | Safety will be assessed by evaluation of incidence of adverse events. |
