Étude NEPC : une étude exploratoire sur l'innocuité et l'efficacité avec la thérapie par radioligand ciblée PSMA, SSTR2 et GRPR dans le cancer de la prostate neuroendocrinien métastatique.
Une étude exploratoire de phase I, ouverte et multicentrique sur l'innocuité et l'efficacité avec la thérapie par radioligand ciblée PSMA, SSTR2 et GRPR dans le cancer de la prostate neuroendocrinien métastatique.
The purpose of this study is to evaluate the change in the expression of treatment targets on the surface of tumor cells (Prostate Specific Membrane Antigen (PSMA), Somatostatin Receptor 2 (SSTR2), and Gastrin Releasing Peptide Receptor (GRPR) between the baseline and following targeted radioligand therapy (RLT). Study will use radioligand imaging (RLI) to determine predominantly expressed target on the surface of tumor cells. Based on predominant expression of target, corresponding RLT targeting PSMA, SSTR2, or GRPR RLT will be given for up to 6 cycles every 6 weeks as intravenous (i.v.) injection in participants with metastatic neuroendocrine prostate cancer (mNEPC).

Description détaillée
The screening period for each participant includes imaging with 3 radioligand imaging (RLI) compounds to assess expression level of PSMA, SSTR2 and GRPR. Participants will be assigned to the radioligand treatment (RLT) corresponding to their predominantly expressed target based on blinded independent central review (BICR). During the treatment period, participants will receive up to 6 cycles of the assigned RLT, corresponding to a total dose of 44.4 GBq (+/-10%) for [177Lu]Lu-PSMA-617 or [177Lu]Lu-DOTA-TATE , and 55.5 GBq (+/-10%) for [177Lu]Lu-NeoB. No crossover to a different type of RLT is allowed.
At least six weeks after receiving the first cycle of RLT, participants must be scanned again with up to 3 RLIs but must be scanned, with at least with one RLI corresponding to the received RLT, which is recommended to be performed first. All post-baseline PET/CT scans should be performed using the same PET/CT imaging agent and same PET/CT camera, acquisition and reconstruction protocols as used for screening PET/CT for the participant.
The post-treatment follow-up period consists of a 42-days Safety follow-up visit.
The planned duration of treatment is up to 36 weeks for all treatment arms in this study, with treatment given every 6 weeks ±7 days. Participants may be discontinued from treatment earlier due to unacceptable toxicity or disease progression, and/or at the discretion of the Investigator or the participant.
Protocol Amendment 7 follows the Sponsor's business decision to halt enrollment on 05-Jan-2026. The premature closure of the trial was not driven by any safety concerns identified in the study to date.

The analysis of biodistribution and dosimetry endpoints will consist of descriptive summaries and graphical presentations of the derived parameters. For each of the treatments, the absorbed dose by body organs and tumor lesions will be determined by calculation of TACs obtained from the radiotracer uptake (as percentage of injected dose) in selected organs and lesions (coming from image quantification). |
Cycle 1 Day 1 (each cycle is 42 days), Cycle 1 Day 2, Cycle 1 Day 3, Cycle 1 Day 8, Cycle 3 Day 1, Cycle 3 Day 3, Cycle 5 Day 1, Cycle 5 Day 3 (Cycle 3 Day 2, Cycle 3 Day 8, Cycle 5 Day 2 and Cycle 5 Day 8 where required by local authorities)
