Study Description

Brief summary:

Endometrial carcinoma is the most common gynecologic cancer in the western world. Two types are usually described. Type I is the endometrioid and is usually estrogen dependent. Type II is usually more aggressive than type I and is estrogen independent. Type II endometrial cancer is usually characterized as high grade while type I as low intermediate and high grade. Ovarian carcinoma as opposed to endometrial carcinoma is not characterized by types but by different histological backgrounds. It is also divided into high and low grade tumors. Ovarian carcinoma is considered to be the most aggressive of all gynecological malignancies resulting in most yearly deaths. Our immune system usually responds to foreign intruders entering our body or formed inside and attacks it in order to destroy it. Cancer cells are considered to be foreign to the body hence the immune system is expected to destroy it . The immune mediated cells which are supposed to attack the cancer are called tumor infiltrating lymphocytes or "TILS". Many different cancers possess the ability to evade TILS in order to survive and grow. Many studies have demonstrated that the presence of large number of TILS improved cancer prognosis. One of these evasive methods is the PD-1/PDL-1 expression. The question whether more aggressive tumors possess better capabilities to evade an immune response via the PD-1/PDL-1 mechanism is currently unknown. All tumor types possess antigens on their cell surface which triggers an immune response to some extent. Even though, the tumor needs different methods in order to be able to avoid the immune system attack. TILS express the PD-1 receptor on their cell surface and when it binds to PDL-1 or PDL-2, the cells which express the ligand deactivate TILS hence deem the lymphocyte incapable of inducing programmed cell death. PDL-1 which is expressed on tumor cells to evade an immune response can be targeted by immunotherapy.

Study Recruitment Status:

Glossary term:

Recruitment status
Not yet recruiting: The study has not started recruiting participants. Recruiting: The study is currently recruiting participants. Enrolling by invitation: The study is selecting its participants from a population, or group of people, decided on by the researchers in advance. These studies are not open to everyone who meets the eligibility criteria but only to people in that particular population, who are specifically invited to participate. Active, not recruiting: The study is ongoing, and participants are receiving an intervention or being examined, but potential participants are not currently being recruited or enrolled. Suspended: The study has stopped early but may start again. Terminated: The study has stopped early and will not start again. Participants are no longer being examined or treated. Completed: The study has ended normally, and participants are no longer being examined or treated (that is, the last participant's last visit has occurred). Withdrawn: The study stopped early, before enrolling its first participant. Unknown: A study on ClinicalTrials.gov whose last known status was recruiting; not yet recruiting; or active, not recruiting but that has passed its completion date, and the status has not been last verified within the past 2 years.
This Study is for people with:
The sample consists of 100 patients from all ages and races. These patients have to be diagnosed with either ovarian or endometrial carcinoma of all stages and grades. In addition, the cancerous specimen needs to stain positive for PD-1/PDL-1.
Age Eligible:

Glossary term:

A type of eligibility criteria that indicates the age a person must be to participate in a clinical study. This may be indicated by a specific age or the following age groups: The age groups are: Child (birth–17) Adult (18–64) Older adult (65+)
Sexes Eligible:

Glossary term:

A type of eligibility criteria that indicates the sex of people who may participate in a clinical study (all, female, male). Sex is a person's classification as female or male based on biological distinctions. Sex is distinct from gender-based eligibility.
Study Accepts Healthy Volunteers:

Glossary term:

Accepts Healthy Volunteers
A type of eligibility criteria that indicates whether people who do not have the condition/disease being studied can participate in that clinical study.
Intervention Being Studied:
Diagnostic Test: PD-1/PDL-1 staining
Type of Study:

Glossary term:

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. Interventional studies (clinical trials): A type of clinical study in which participants are assigned to groups that receive one or more intervention/treatment (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. The assignments are determined by the study's protocol. Participants may receive diagnostic, therapeutic, or other types of interventions. Observational studies: A type of clinical study in which participants are identified as belonging to study groups and are assessed for biomedical or health outcomes. Participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to a specific intervention/treatment. A patient registry is a type of observational study. Expanded access: A way for patients with serious diseases or conditions who cannot participate in a clinical trial to gain access to a medical product that has not been approved by the U.S. Food and Drug Administration (FDA). Also called compassionate use. There are different expanded access types.
Enrollment (Anticipated):

Glossary term:

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

Glossary term:

The organization or person who initiates the study and who has authority and control over the study.

Study Start Date (Anticipated):

Glossary term:

Study start date
The actual date on which the first participant was enrolled in a clinical study. The "estimated" study start date is the date that the researchers think will be the study start date.

August 25, 2020

Study Completion (Anticipated):

Glossary term:

Study completion date
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 "estimated" study completion date is the date that the researchers think will be the study completion date.
