Trial summary

Maternal malignancy during pregnancy is estimated to occur in 1 out of 1000 pregnancies. Controversy exists regarding the effect of pregnancy on cancer prognosis. Gestational hormones and pregnancy-related growth factors may induce a more aggressive behavior in malignant cells. Read more about this study

About this study

Maternal malignancy during pregnancy is estimated to occur in 1 out of 1000 pregnancies. Controversy exists regarding the effect of pregnancy on cancer prognosis. Gestational hormones and pregnancy-related growth factors may induce a more aggressive behavior in malignant cells. However, metastasis to the products of conception is rare. In the current study investigators wish to analyze the effect of placental explants on cancer cells (cervical, ovarian, thyroid, melanoma, lymphoma, leukemia and breast)phenotype (cell death, proliferation, migration , invasion), signaling pathway, mRNA, miRNA and protein expression.

Read the detailed description

In the Oncogenetic laboratory cancer cells will be exposed to first trimester human placental explants or to serum collected from pregnant women. As a control cancer cells will be cultured alone or in the presence of sera collected from young (18-45) non pregnant women.

Placentae, 6-9 weeks gestational age, will be retrieved from terminated normal pregnancies. The placenta will be taken after pregnancy termination, thus, no harm will be caused for the women.

The sera will be collected from the women by an authorized physician. It will be taken from: 1. the vein of the non pregnant women and volunteered pregnant women. 2. from the same branula that will be introduced into the pregnant women as a routine during pregnancy termination procedure.

Following culture investigators will analyze the cancer cells phenotype (cell death, proliferation, migration, and invasion), signaling pathway, mRNA, miRNA and protein expression.

Sera will be collected from 50 pregnant women and 50 non pregnant women. Placentae will be collected from 50 pregnant women.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01879436
Study groupRoleWhat they receive
Pregnant womenWomen during first trimester of pregnancy (age: 18-45) Group contain 50 healthy pregnant women, age 18-45. Sera will be taken from: 1. the same branula that will be introduced into the pregnant women as a routine during pregnancy termination procedure.2. from the vein of volunteered pregnant women which do not terminate pregnancy. First trimester placenta will be collected after pregnancy termination. The measure of outcome is composite and includes several changes: Changes in: * cell death (% from tested cells) * cell cycle (% cells in G1, G2 and S phases) * cell migration (% closure in Scratch test) * cell invasion (% cells passing through membrane in Transwell assay) * RNA repertoire (Fold change) * miRNA repertoire (Fold change) Investigators will not treat the women with any drug.
Non pregnant womenGroup contain 50 healthy women, age 18-45. Sera will be taken from the vein of the volunteered women. Investigators will not treat the women with any drug.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cancer cell phenotype (in the laboratory)

    The measure of outcome is composite and includes several changes:

    Changes in:

    • cell death (% from tested cells)
    • cell cycle (% cells in G1, G2 and S phases)
    • cell migration (% closure in Scratch test)
    • cell invasion (% cells passing through membrane in Transwell assay)
    • RNA repertoire (Fold change)
    • miRNA repertoire (Fold change)

    Measured: Baseline, 24 hours and 72 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer, run by Meir Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cancer cell phenotype (in the laboratory) (time frame: Baseline, 24 hours and 72 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01879436, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2020.
