Background and study aims
Rheumatoid arthritis is a long-term condition that causes pain, swelling and stiffness in the joints.
This research study is about obtaining white blood cells using a routine procedure, leukapheresis (a laboratory procedure in which white blood cells are separated from a sample of blood), in order to produce a new treatment for rheumatoid arthritis (RA) known as tolerogenic dendritic cells (tolDC). Therapy with tolDC has great potential for the treatment of conditions caused by problems with the immune system, such as RA.
We are now preparing to carry out a clinical trial to test the best administration route of tolDC and look any effects the treatment has on the immune system in RA patients. Before carrying the clinical trial we need to adapt the way tolDCs are made so that they can be followed in the body. We need to demonstrate that the manufacturing process for the altered tolDC therapy is tested (validated) and ensure that it is at clinical grade standard before use in patients.
It is not feasible to obtain the quantity of white blood cells needed to make clinical-grade tolDC from routine blood donations, therefore, six participants with RA will be recruited to donate white blood cells by leukapheresis as part of this study. This study concerns the validation of the manufacturing process only.
The study aim is to collect white blood cells from rheumatoid arthritis patients to use for GMP validation of the manufacturing process of tolerogenic dendritic cells (tolDC).

Who can participate?
Patients aged 18 years or older, with ACPA positive rheumatoid arthritis and who are able to provide informed consent are able to participate.

What does the study involve?
This research study involves obtaining white blood cells using a routine procedure called leukapheresis. White blood cells will be collected once and will be used to produce a new treatment for Rheumatoid Arthritis (RA); tolerogenic dendritic cells (tolDC). Participants will under a screening process before the procedure which involved taking blood samples.

What are the benefits and risks of participating?
Participants will not receive any treatment as part of the study. There is no direct benefit to the participant though the study findings will be used to inform the manufacture of a new treatment for patients with RA.
Leukapheresis is carried out routinely in the haematology ward and you will be looked after by experienced members of staff. As with all medical procedures there are risks associated with leukapheresis but routine procedures are in place to minimise these risks.

Where is the study run from?
Newcastle University (UK)

When is the study starting and how long is it expected to run for?
December 2018 to June 2022.

Scientific titleCollection of white blood cells [using leukapheresis] from rheumatoid arthritis patients for the validation of an advanced treatment for rheumatoid arthritis (tolDC)
Study objectivesThe purpose of this study is to collect samples of leukocytes from Rheumatoid Arthritis (RA) patients which can be used to validate the production and quality of an advanced therapy medicinal product (tolDC).
Ethics approval(s)Approved 22/07/2020, Yorkshire & The Humber - Sheffield Research Ethics Committee (NHSBT Newcastle Blood Donor Centre, Holland Drive, Newcastle upon Tyne, NE2 4NQ, UK; +44 (0)207 104 8237; sheffield.rec@hra.nhs.uk), ref: 20/YH/0203
Health condition(s) or problem(s) studiedRheumatoid arthritis
InterventionLeukocytes will be collected from Anti-citrullinated protein antibody (ACPA) positive Rheumatoid Arthritis (RA) patients and used for the GMP process and product validation of an advanced therapy medicinal product, called tolDC.

Leukocyte samples, used to manufacture tolDC, will be collected from participants by leukapheresis.

Participants will be asked to undergo a number of screening assessments including ECG and blood tests to confirm that they have no contraindications to leukapheresis. Participants meeting all the ineligibility criteria will undergo a single cycle of leukapheresis to obtain the leukocyte sample.

The acquired leukocyte samples will be transferred to the Newcastle Cellular Therapies Facility, a sterile GMP (Good Manufacturing Practice) facility, where the tolDC manufacture and validation work will be carried out.
Intervention typeOther
Primary outcome measureThe number of patients who successfully complete the leukaphereis procedure, where success is determined by the collection of a leukocyte sample of 100mls at a single time point
Secondary outcome measuresProperties of the final product measured at a single time point:
1. Cell number measured using Flow cytometry
2. Viability measured using Flow Cytometry/Trypan Blue Exclusion Assay (TBC)
3. Yield (number compared to cells at the start of the process) measured using Flow Cytometry
4. Purity (number of TolDC cells compared to non-TolDC cells) measured using Flow Cytometry
5. Potency (ability of cells to function as intended) measured using Functional assay measuring IFNy in co-culture
Overall study start date01/12/2018
Completion date30/06/2022
