Clinical Trial Summary

Systemic sclerosis or scleroderma is an autoimmune condition that cause thickening and hardening of the skin, but can also affect internal organs. There are two major subsets of scleroderma: the limited cutaneous systemic sclerosis (lcSSc) that usually affects the skin of the face, neck, lower legs or lower arms, but can also lead to internal organ complications, and the diffuse cutaneous systemic sclerosis (dcSSc) that may affect blood circulation and internal organs, as well as the skin. To date there is no drug that has been definitively proven to cure or modify the course of scleroderma. However, there is emerging evidence that immunosuppression and specifically mycophenolate mofetil (MMF) may be beneficial in lcSSc. The MINIMISE-Pilot trial would be an important first step to evaluate the risk and potential benefit to this disease group. MMF as the intervention of choice is both appropriate and timely, as it has been routinely used in the management of dcSSc. The aim of this pilot trial is to explore whether the immunosuppressive agent MMF can slow down disease progression in patients with lcSSc compared to the current standard of care alone. This pilot trial will also provide critical information for the development of a future large trial that could potentially transform lcSSc patient management.

Description:

The MINIMISE-Pilot trial aims to explore whether the immunosuppressive agent mycophenolate mofetil (MMF) at a target dose of 2g daily can slow down disease progression in patients with limited cutaneous systemic sclerosis (lcSSc) compared to the current standard of care alone. This pilot trial will also provide critical information for the development of a future large trial that could potentially transform lcSSc patient management. This is an open label randomised prospective trial that will recruit 120 participants aged 18 and older with limited cutaneous systemic sclerosis across 13 sites in the UK. Following a screening visit, eligible participants will attend a baseline visit where they will be randomly allocated into one of two groups; MMF or Control. Those in the first group are given mycophenolate mofetil (MMF) taken daily by mouth for up to 96 weeks, in addition to their background Standard of Care medication for SSc related symptoms. Those in the second group will not receive any MMF but will remain on their standard of care medication alone. Participants are expected to be followed up for a minimum of 48 weeks or a maximum of 96 weeks. The trial will involve five (5) clinic visits which are expected to be carried out at the same time of the participants' normal hospital appointment with their scleroderma specialist. Participants from both groups will have the same assessments. Participants are expected to return to the clinics at Week 24, 48, 72 and 96. However, participants allocated to the MMF group will have additional blood samples taken for safety monitoring every 2 weeks for the first 8 weeks, then every 4 weeks for the following 12 weeks. Thereafter, every 12 weeks up to their final visit. All the participants will receive four (4) routine telephone calls in between their clinic visits.
