Infusion of Allogeneic Mesenchymal Stem Cells in Patients With Diffuse Cutaneous Systemic Sclerosis With Refractory Pulmonary Involvement

April 4, 2024 updated by: Universidad de la Sabana

Infusion of Allogeneic Stromal Mesenchymal Stem Cells From Wharton´s Jelly in Patients With Diffuse Cutaneous Systemic Sclerosis With Refractory Pulmonary Involvement to Treatment

Progressive SSc is an entity with limited therapeutic alternatives and with asurvival rate of less than 45% in the first 3 to 5 years. The disease causessevere limitation in quality of life ranging from functional limitation to depression. Up to 20% of patients will be refractory to conventional treatment with diseasemodifying anti-rheumatic drugs (DMARDs) and cyclophosphamide therapy.This favors the progression to visceral involvement including gastrointestinal,lung and pulmonary hypertension. The latter being a poor prognostic factor,increases mortality in this group of patients and drastically affects their qualityof life. For this reason, different therapeutic options have been considered including cell transplantation and Stem Cell use. Among the options that have been studied so far are stromal mesenchymal cells from Wharton ́s jelly. These have been used in intravenous infusion or direct application in different disease scenarios ranging from vascular involvement to interstitial lung involvement and cases of pulmonary hypertension, with promising results in terms of clinical progression,improvement in quality of life and prognostic indices. This therapy has proven to have a significant margin of safety at the time of administration and a low rate of adverse events, a self-limiting fever as the most frequent event. Based on the above and considering the possibility of offering patients without therapeutic alternatives to their disease in addition to palliative options, an intravenous infusion of stromal mesenchymal stem cells from Wharton ́s jellyis proposed for three patients with progressive SSc refractory to conventional therapy with pulmonary involvement due to pulmonary hypertension.

Under this premise the question posed in our work is; What are the effects of the infusion of allogeneic mesenchymal stromal cells from Wharton ́s jellyin patients with systemic sclerosis refractory to conventional treatment with Methotrexate or Cyclophosphamide in a population of three patients with severe pulmonary involvement due to pulmonary hypertension.

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

This study aims to evaluate the therapeutic effects of allogeneic mesenchymal stromal cell infusion as a treatment in patients with systemic sclerosis refractoryto conventional therapy. The group of patients will be collected from the database of families of Stem Regenerative Medicine according to the inclusion and exclusion criteria and verified in the academic committee.

The administration will be intravenously, with a concentration of 2 X 10^6 mesenchymal cells per kilogram of patient weight. The infusions will be carried out nested at cyclophosphamide application cycles ten days after each application of the cyclophosphamide schedule for each patient. To assess safety and therapeutic effects, the occurrence of any adverse event will be described from start of infusion until the conclusion of the trial in six months.

To assess the response, a pre-infusion and sixth-month post-infusion instrument will be applied that includes clinical variables, paraclinical and hemodynamic tests to evaluate skin involvement using the modified RODNAN score, changes in nail capillaroscopy, lung function and structural involvement by high-resolution chest tomography (hrCT), diffusion capacity for carbon monoxide (DLCO) and a 6-minute walk. As part of the cardiovascular assessment, cerebral natriuretic peptide (BNP), transthoracic echocardiogramwill be performed; The Cambridge Pulmonary Hypertension Outcome Review(CAMPHOR) and Sysq will be used as tools for the assessment of pulmonary hypertension. A comparison of these tests before initiation of therapy and after completion of 24 weeks of infusion scheme should be performed.

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.
Expanded Access

Expanded Access Type

Expanded Access Type

Describes the category of expanded access under U.S. Food and Drug Administration (FDA) regulations. There are three types of expanded access:
  • Individual Patients: Allows a single patient, with a serious disease or condition who cannot participate in a clinical trial, access to a drug or biological product that has not been approved by the FDA. This category also includes access in an emergency situation.
  • Intermediate-size Population: Allows more than one patient (but generally fewer patients than through a Treatment IND/Protocol) access to a drug or biological product that has not been approved by the FDA. This type of expanded access is used when multiple patients with the same disease or condition seek access to a specific drug or biological product that has not been approved by the FDA.
  • Treatment IND/Protocol: Allows a large, widespread population access to a drug or biological product that has not been approved by the FDA. This type of expanded access can only be provided if the product is already being developed for marketing for the same use as the expanded access use.
  • Intermediate-size Population

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 to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
