Autologous Tolerogenic Dendritic Cells for Treatment of Patients With Rheumatoid Arthritis (TolDCfoRA)

September 11, 2019 updated by: Alexander A Ostanin, Russian Academy of Medical Sciences

Safety/Efficacy of Intra-articular Administration of Autologous Tolerogenic Dendritic Cells for Treatment of Patients With Rheumatoid Arthritis

Tolerogenic dendritic cell (tDC)-based clinical trials for the treatment of autoimmune diseases are now a reality. Clinical trials are currently exploring the effectiveness of tDC to treat of type 1 diabetes mellitus, rheumatoid arthritis, multiple sclerosis and Crohn's disease. The general objective of this study is to evaluate the safety and tolerability of a single intra-articular injection (into the knee joint) of autologous monocyte-derived dendritic cells generated in the presence of interferon-alpha (IFN-α)/granulocyte-macrophage colony-stimulating factor (GM-CSF) and tolerized with Dexamethasone in rheumatoid arthritis (RA) patients.

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

A phase I dose-escalating clinical trial will be conducted to determine the safety and tolerability of a single intra-articular injection (into the knee joint) of autologous tolerogenic dendritic cells, and to enable selection of a suitable dose regimen for phase II trial. The primary objective of the phase I study will be to determine whether tDC-based therapy is safe and well tolerated and to establish the dose-response with disease activity measured over 6 months. Patients will serve as their own controls (pre- and post-treatment). Five doses of tDCs will be tested. The Study will start with intra-articular injection (into the knee joint) of 1x106 cells. Depending on safety/tolerability outcomes, the dose will gradually increase to 3x106, 5x106, 8x106 and 10x106 cells. The safety will be determined by the evaluation of the number of participants with adverse events (AEs) and severe adverse events (SAEs) following the intra-articular administration of tDC (within 6 months of injection). Systemic RA disease activity will be measured using DAS28 (Disease Activity Score using 28 joints) and the Health Assessment Questionnaire (HAQ), a standard instruments used in RA. Patients will be monitored at baseline and at 3, 7 days and 1, 3, 6 months post treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

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
Number of Participants experiencing AEs and SAEs following the intra-articular administration of tDCs.
Time Frame: within 6 months of injection
Occurrence and severity of adverse events following the intra-articular administration of tDCs will be evaluated within 6 months of injection.
within 6 months of injection

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
Number of Participants Who Rated the Study and its Components as Partly or Completely Acceptable.
Time Frame: At final study visit, 6 months post treatment
Participants will assess acceptability of study specific procedures via an "acceptability questionnaire" administered at the last study visit.
At final study visit, 6 months post treatment
Change from Baseline in DAS28 Score.
Time Frame: Baseline, 1, 3 and 6 months post treatment
DAS28 calculated from the swollen joint count (SJC) and tender joint count (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour) and Patient Global Assessment of disease activity (participant-rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity). A clinically meaningful improvement in DAS28 was defined as an improvement of 1.2 units.
Baseline, 1, 3 and 6 months post treatment
Change from Baseline in the Health Assessment Questionnaire (HAQ)
Time Frame: Baseline, 1, 3 and 6 months post treatment
Functional status (disability) of participants will be assessed using the Health Assessment Questionnaire (HAQ), a standard instrument used in RA.
Baseline, 1, 3 and 6 months post treatment
