Understanding the Role of Large Extracellular Vesicles in Lymphomas and Lymphoproliferative Disorders: the "Off the Beaten Track" Liquid Biopsy - A Prospective Monocentric in Vitro Study on Human Tissues

This study aims to investigate the role of extracellular vesicles as diagnosic and prognostic biomarkers in patients with lymphomas or lymphoproliferative disorders. In particular, circulating extracellular vesicles, thanks to their cargo of proteins, lipids, and nucleic acids, play a role in the communication between cells. Since it has been described that these vesicles are able to influence also immune cells, the study of their functions may lead to the discovery of new mechanisms underlying this type of diseases.

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.

Detailed Description

It is a 3-year monocentric in vitro study on human tissue. 50 patients with aggressive and indolent Non-Hodgkin Lymphomas (Diffuse Large B-Cell Lymphoma (DLBCL; Group A; n=10), Follicular Lymphoma (FL; Group B; n=10), Marginal Zone Lymphoma (MZL; Group C; n=10), Peripheral T-Cell Lymphoma (PTCL; Group D; n=10), Mycosis Fungoides (MF; Group E; n=10)), and patients with Chronic Lymphocytic Leukaemia (CLL; N=10; Group F; n=10), Hairy Cell Leukemia (HCL; Group G; n=10), and Multiple Myeloma (MM; N=10; Group H; n=10) will be enrolled over a period of 24 months. Follow-up: 12 months. Patients will be enrolled at the Complex Operative Unit of Haematology-IRCCS Azienda Ospedaliero-Universitaria di Bologna. The peripheral blood samples of patients (40 ml) will be collected only at diagnosis within normal clinical practice, outside of clinical study protocols, and following the treatment guidelines in use at the Centre. The analysis of the samples will be performed at the Unità Operativa Complessa di Ematologia-IRCCS Azienda Ospedaliero-Universitaria di Bologna in collaboration with the Istituto Romagnolo per lo Studio dei Tumori 'Dino Amadori' - IRST IRCCS and with the University of Perugia.

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
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Patients at diagnosis (Diffuse Large B-Cell Lymphoma, Follicular Lymphoma, Marginal Zone Lymphoma, Peripheral T-Cell Lymphoma, Mycosis Fungoides, Chronic Lymphocytic Leukemia, Hairy Cell Leukemia, Multiple Myeloma) will be enrolled over a 24 month period. Follow-up 1 year.

Sex/age matched healthy donors will be recruited for peripheral blood collection among volunteers of a no profit organization called Bologna AIL.

Description

Inclusion criteria for patients:

  • Age ≥ 18 years.
  • Patients with WHO 2017-defined diagnosis of indolent and aggressive Non-Hodgkin Lymphoma (specifically Diffuse Large B-Cell Lymphoma, Follicular Lymphoma, Marginal Zone Lymphoma, Peripheral T-Cell Lymphoma, Mycosis Fungoides) or Chronic Lymphocytic Leukemia or Hairy Cell Leukemia or Multiple Myeloma.
  • Signed informed consent.

Exclusion criteria for patients:

- Concomitant secondary neoplasia.

Inclusion criteria for healthy donors:

  • Age ≥ 18 years.
  • Signed informed consent.

Exclusion criteria for healthy donors:

- Healthy donors with neoplasia.

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
Extracellular vesicle characterization
Time Frame: 2 years
Comparison of concentration (particles/ml), phenotype, and cargo of extracellular vesicles from patients and healthy donors.
2 years
Validation of extracellular vesicles as biomarker
Time Frame: 2 years
Correlation of extracellular vesicles' characterization results with biomarkers of disease aggressiveness and short-term response to standard therapy.
2 years

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
Functional effects of extracellular vesicles
Time Frame: 2 years
Comparison of functional effects of extracellular vesicles from patients and healthy donors on selected immune cells. The isolated vesicles will be used to treat the immune cells (T cells, B cells, monocytes) to evaluate viability, phenotype, migration ability, and inflammatory cytokine production of the target cells.
2 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Extracellular vesicles' cell of origin
Time Frame: 1 years
Correlation of extracellular vesicles' phenotype with the corresponding cells of origin.
