Does Immunotherapy Have a Role in the Management of Endometriosis?

August 12, 2018 updated by: Hale GOKSEVER CELIK, Kanuni Sultan Suleyman Training and Research Hospital
Pathological specimens of 40 women that had been operated for endometriosis will be included in this study. These tissues will be stained with a marker named as PDL-1 in pathological examination. "programmed cell death (PD-1)" is expressed on T cells. The immunotherapies in which antibodies against these PD-1 and its ligands (PDL-1) have been used are accepted as very effective in the treatment of many cancers. If these ligands can be shown in the endometriosis, it will be an important step for the treatment of endometriosis.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

40 women who had been operated for endometriosis between 2013 and 2014 will be included in this study. Pathological specimens will be stained with an immunohistochemical marker named as PDL-1. "programmed cell death (PD-1)" is a protein containing 288 aminoacids and expressed on T cells. It was shown on apoptotic cells in earlier times, but then it has been understood that its physiologic role is not cell death. The upregulation of PD-1 is a result of the activation of T cells and it is necessary for the termination of immune response. PD-L1 is a ligand for PD-1. The immunotherapies in which antibodies against these PD-1 and its ligands (especially PDL-1) provides significant improvements in many cancers such as melanoma. Evidence about the role of these ligands in endometriosis will be an important step in its management.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
40

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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2018

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
