Effects of ASC Secretome on Human Osteochondral Explants (ASC-OA)

October 18, 2024 updated by: I.R.C.C.S Ospedale Galeazzi-Sant'Ambrogio

Secretome from Mesenchymal Stem/stromal Cells on Human Osteochondral Explants: Cocktail of Factors Secreted by Adipose-derived Stromal Cells (ASC) for the Treatment of Osteoarthritis And/or for Articular Regeneration

Since the need of finding effective disease-modifying anti-osteoarthritis (OA) treatments is still unmet, with this study the investigators aim to gather further evidences of the therapeutic potential of Mesenchymal Stem/stromal Cell (MSC) secretome in order to pave the way to its future use as a cell-free biological product. In detail, the investigators predict to validate the promising results obtained in vitro, ex vivo on osteochondral explants, an OA model more representative of the physiological situation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Upon signing the Informed Consent, 24 male/female patients undergoing orthopedic surgery at IRCCS Istituto Ortopedico Galeazzi and matching the inclusion and esclusion criteria will be recruited.

Description

Inclusion Criteria:

  • males and females
  • age≥18 years old
  • patients hospitalized in IRCCS (Istituto di Ricovero e Cura a Carattere Scientifico) Istituto Ortopedico Galeazzi, undergoing arthroplasty

Exclusion Criteria:

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
Validation of the cell-free approach based on the use of ASC secretome on an ex vivo OA model by evaluation of cell viability, histological features and gene/protein expression of cartilage and bone biomarkers
Time Frame: 3 years

Biochemical and functional characterization of untreated osteochondral explants (to set up the model) and explants treated with inflammatory cytokines (to simulate osteoarthritic pathology) by evaluation of several parameters. The multiple measurements that will concur to describe the phenotype of the specimens are the following:

  • cell viability by AlamarBlue (Arbitrary Fluorescence Units).
  • histological assessments (qualitative differences between specimens).
  • analysis of gene expression by RT-PCR (real-time polymerase chain reaction, relative quantification by 2-ΔΔCT method).
  • analysis of protein expression by Western Blot (relative quantification by densitometry) and Luminex (pg/ml).

Evaluation of the effects of ASC secretome (either complete conditioned medium or its subcomponents) on osteochondral biopsies treated with inflammatory cytokines through the biochemical and functional analyses described above.

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 (Actual)

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.
April 12, 2021

Primary Completion (Actual)

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.
