Cancer Clinical Trial - Study of Polyfunctionality of Anti-tumor T

Status Not yet recruiting

Clinical Trial Summary

Purposes of this study are :

- Characterization of polyfunctionality of anti-tumor T lymphocytes using in vitro inhibition of PD-1/PDL-1 pathway

- Study and comparison of polyfunctionality of anti-tumor T lymphocytes in cohorts of patients with melanoma, lung cancer and renal carcinoma. This cancers are chosen because of use of anti-PD-1 or anti-PDL-1 antibodies

- Comparison of this technique with IFN-γ Elispot assay for detection and quantification of anti-tumor T lymphocytes after in vitro blockade of PD-1/PDL-1 pathway.

Clinical Trial Description

In this study an immunomonitoring of specific responses of T lymphocytes to tumor-associated antigens based on detection of intracellular cytokines through flow cytometry, after stimulation with all-tumor antigens and blockade of PD-1/PDL-1 interaction is used. Peripheral blood mononuclear cells of patients with cancers are stimulated with 4 telomerase-peptides or peptides overlapping the entire sequence of survivin.

This project studies the frequency and role of polyfunctionality of anti-tumor T lymphocytes in cancerology with an in vitro technique detecting polyfunctional T lymphocytes with a better sensitivity based on removal of an inhibitory PD-1/PDL-1 pathway. It is a flow cytometry protocol with various theoretical advantages in terms of reproducibility and dynamic monitoring of functionality of different sub-populations of polyfunctional anti-tumor T lymphocytes. Moreover, it allows the study of molecular mechanisms involved in proliferation of polyfunctional anti-tumor T lymphocytes with the possibility to sort sub-populations.

The use of all-tumor antigens allows the use of this technique to evaluate the presence and prognostic or predictive value of this biomarker in various cancers.

Detection of polyfunctional anti-tumor T lymphocytes can be a biomarker of anti-tumor lymphocytic adaptive immunity and a potential eligibility or efficacy criteria for new immunotherapies, such as anti-PD-1 or anti-PDL-1 treatments. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
