Spots Global Cancer Trial Database for Evaluation of the Relationship Between Anti-PD-1 Exposure and Tumour VOLUME in Patients Treated for Classical HODgkin's Lymphoma.

Study Description

Brief Summary: Anti-PD-1antibodies (iPD-1) are indicated as monotherapy in the treatment of adult patients with classical LH. The recommended dosage in LH is based on solid tumour experience and no dose-concentration-effect studies have been conducted. According to the literature, therapeutic efficacy appears to be highly variable, and could be related to differences in treatment exposure. Since Total metabolic tumor volume (TMTV) is a prognostic factor in LH and the clearance of iPD-1, and thus exposure to iPD-1, is related to clinical efficacy, we hypothesize that TMTV influences the exposure to iPD-1 and thus its therapeutic efficacy. The aim of this study is to evaluate the relationship between TMTV and anti-PD-1 exposure in refractory or relapsed LH.

Detailed Description: Anti-PD-1antibodies (iPD-1), nivolumab (NIV) and pembrolizumab (PEM), act by blocking the interaction of the PD-1 receptor with its PDL1/PDL-2 ligands, which are overexpressed by tumour cells and their microenvironment, thus restoring an effective anti-tumour response. NIV and PEM are indicated as monotherapy in the treatment of adult patients with classical LH. They are administered as intravenous infusions on an outpatient basis. The recommended dosage for IVN or EMP in LH is based on solid tumour experience and no dose-concentration-effect studies have been conducted. According to the literature, therapeutic efficacy appears to be highly variable, and could be related to differences in treatment exposure. Since Total metabolic tumor volume (TMTV) is a prognostic factor in LH and the clearance of iPD-1, and thus exposure to iPD-1, is related to clinical efficacy, we hypothesize that TMTV influences the exposure to iPD-1 and thus its therapeutic efficacy. The aim of this study is to evaluate the relationship between TMTV and anti-PD-1 exposure in refractory or relapsed LH. Highlighting such a relationship will make it possible to identify treatment algorithms according to the initial TMTV with a target plasma concentration defined according to the TMTV measurement. New therapeutic biomarkers would thus be highlighted. This personalised medicine approach would make it possible to maximise the effect while reducing toxicity. This project is a first step in the implementation of a clinical study leading to recommendations for anti-PD-1 dose adaptation based on concentration and TMTV.
