Identify a Specific Immune Profile in Patients With Chronic Pelvic Pain Resistant to First-line Treatments by Measuring Th1, Th2, Th17, and Treg Cytokines Produced After Non-specific Functional Cell Stimulation - ImmunoCPP (ImmunoCPP)

February 17, 2026 updated by: Centre Hospitalier Universitaire de Nice
Chronic pelvic pain (CPP) affects more than one in four women. An immune imbalance in the Th1/Th2 balance has been reported in multiple CPP situations, particularly in patients with endometriosis, but with mixed results. The use of a functional immune test, already validated in previous indications and particularly in infertility, could simulate an immune stimulation similar to that of painful attacks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group 1 : Patients with pelvic pain
Patients with chronic pelvic pain resistant to hormone therapy
Other: Immune profile
The immune profile will be determined by measuring blood concentrations (in pg/mL) of pro-inflammatory and anti-inflammatory cytokines measured after non-specific stimulation of peripheral blood cells from each patient: IL4, IL5, IL12p70, 1L17A, IFNγ, IL1β, IL6, IL8, IL10, IL15, IL18, TNFα, TGFβ.
Experimental: Group 2 : Asymptomatic patients
Asymptomatic patients undergoing hormone therapy
Other: Immune profile
The immune profile will be determined by measuring blood concentrations (in pg/mL) of pro-inflammatory and anti-inflammatory cytokines measured after non-specific stimulation of peripheral blood cells from each patient: IL4, IL5, IL12p70, 1L17A, IFNγ, IL1β, IL6, IL8, IL10, IL15, IL18, TNFα, TGFβ.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Identify a specific immune profile in patients with chronic pelvic pain, with or without endometriosis, who have failed hormone treatment.
Time Frame: 24 months
Measurement of blood concentrations (in pg/mL) of pro-inflammatory and anti-inflammatory cytokines measured after non-specific stimulation of peripheral blood cells from each patient: IL4, IL5, IL12p70, 1L17A, IFNγ, IL1β, IL6, IL8, IL10, IL15, IL18, TNFα, TGFβ.
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
