Sonde nanocorps spécifique PD-L1 [68Ga]-Nb-1 pour l'imagerie TEP dans les tumeurs solides
To utilize the [68Ga]Ga-THP-PDL1-3 molecular probe to non-invasively detect PD-L1 expression in primary and metastatic lesions of patients with solid tumors. Furthermore, to assess the heterogeneity of PD-L1 expression within the same lesion and across different lesions, and to observe changes in PD-L1 expression during the course of treatment. This approach aims to facilitate patient screening, therapeutic monitoring, and early warning of drug resistance and/or recurrence or metastasis in the treatment of solid tumors with high PD-L1 expression, ultimately enabling personalized targeted therapy in oncology.

Description détaillée
Analysis plan: 1. recruit 10 participants to analyze preliminary pharmacokinetic/first-in-human dose (FIH), major organ distribution and tumor uptake information via whole-body PET/CT imaging; 2. recruit 20-30 participants to analyze in vivo safety and tumor targeting information; and 3. recruit all participants for a final summary.

Expérimental: [68Ga]Ga-THP-PDL1-3
All study participants will be allocated to this arm (single-arm study).Study participants will undergo [68Ga]Ga-THP-PDL1-3 PET/CT scans.After the participant rests quietly for 40 minutes or 1 hour, whole-body imaging of the head and torso will be performed using a United Imaging uEXPLORER Whole-Body PET/CT scanner at 1 h, 2 h, and 3 h post-injection. The scan range will cover from the vertex to the upper third of the thighs. Participants who required a dynamic scan underwent a 40-min serial scan after injection of [68Ga]Ga-THP-PDL1-3. PET/CT static imaging was performed at 2 h and 3 h after injection. |
All study participants will undergo one 18F-FDG PET/CT scan. [68Ga]Ga-THP-PDL1-3 is an investigational tracer, and all participants will undergo [68Ga]Ga-THP-PDL1-3 scanning. |

Standardized Uptake Value (SUV)
Délai: Quantitative analysis was performed at all imaging time points within two weeks after the end of imaging.
|
Parameters of SUV The maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean) and tumor/background ratio (SUVR) of [68Ga]Ga-THP-PDL1-3 in target lesions were observed. SUVR was calculated as the SUVmax of the target lesion divided by the SUVmean of the reference normal tissue. |
Quantitative analysis was performed at all imaging time points within two weeks after the end of imaging.

Plan pour les données individuelles des participants (IPD)
Prévoyez-vous de partager les données individuelles des participants (DPI) ?
Description du régime IPD
In accordance with the ICMJE data-sharing guidelines and Chinese data-privacy laws, raw clinical and imaging data were not publicly available to prevent compromise of patient privacy. However, the corresponding author will share deidentified patient-level data, imaging parameters (SUV values), and study protocol details if reasonably requested by the requestor.
Délai de partage IPD
Data access will be granted through a secure data sharing agreement for a period of 3 years after publication.
Critères d'accès au partage IPD
Applicants must provide a methodologically sound research plan and obtain approval from their institutional ethics committee.
