简要总结
This is a two center, single arm, investigator sponsored trial (IST) with the PET tracer 89Zr-pembrolizumab to evaluate in vivo whole body distribution of 89Zr-Pembrolizumab in a registered indication: locally advanced metastatic melanoma or non-small cell lung cancer before Pembrolizumab treatment.
详细描述
Rationale: Immunotherapy targeting specific immune-regulatory checkpoints, mainly cytotoxic T-lymphocyte antigen-4 (CTLA-4) and Programmed Death (PD1) or PD ligand 1 (PD-L1) have shown spectacular effects in a broad range of solid malignancies, including melanoma and non-small cell lung cancer (NSCLC). Pembrolizumab, is a monoclonal antibody that blocks the interaction between PD-1 on T-cells with its ligands PD-L1 and PD-L2. Anti-tumor activity with an acceptable side effect profile have been shown in melanoma and NSCLC.
Radio-labeling of pembrolizumab with the positron emission tomography (PET) radionuclide 89Zirkonium (89Zr) enables serial non-invasive imaging and quantification of distribution of PD-1 in melanoma patients. By performing a 89Zr-pembrolizumab-PET scan prior to treatment with pembrolizumab, the uptake of the tracer in the tumor lesions and normal organ distribution can be evaluated, this could lead to new insights about heterogeneity of PD-1 expression, as well as the use of a 89Zr-pembrolizumab-PET as a complementary tool for patient selection in the future.
Objective: Primary objective: To evaluate whole body distribution of 89Zr-pembrolizumab in patients with locally advanced or metastatic melanoma or NSCLC. Secondary objectives: i) To evaluate pharmacokinetics of 89Zr-pembrolizumab; ii) To assess the heterogeneity of 89Zr-pembrolizumab tumor uptake; iii) To describe safety of 89Zr-pembrolizumab; iv) To correlate the tumor response of pembrolizumab, as measured by objective response rate (ORR) according to standard RECIST v1.1 as assessed by the investigator, with specific tumor tracer uptake.
Study design: This is a two center, single arm, investigator sponsored trail (IST) with the PET tracer 89Zr-pembrolizumab to evaluate in vivo whole body distribution of 89Zr-pembrolizumab in a registered indication for locally advanced metastatic melanoma or NSCLC before Pembrolizumab treatment.
Study population: Eligible are patients with locally advanced or metastatic melanoma or NSCLC, who are eligible to receive Pembrolizumab treatment and who have at least one tumor site that is accessible for a tumor biopsy.
