Mycophenolate for Systemic Sclerosis

(IMPACT-SSc Trial)

This trial explores whether Mycophenolate Mofetil (MMF), a medication commonly used for rheumatic diseases, can prevent the return of systemic sclerosis after a stem cell transplant (AHSCT). Participants will either receive MMF or follow the current standard care, which excludes MMF. Ideal candidates are adults undergoing stem cell transplants at The Ottawa Hospital for systemic sclerosis treatment. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.

Studies have shown that Mycophenolate Mofetil (MMF) is generally safe and well-tolerated. This medication is often used for conditions like systemic sclerosis and has been shown to help slow the disease's progression. Research indicates that MMF does not cause serious side effects. However, some people might experience issues such as stomach problems or infections, which can sometimes lead to discontinuing the treatment. Overall, MMF has a good safety record, with many patients able to continue using it without major issues.¹²³⁴⁵

Unlike the standard of care for systemic sclerosis, which typically involves immunosuppressants like methotrexate or cyclophosphamide, Mycophenolate Mofetil (MMF) acts differently by specifically targeting the proliferation of immune cells. This precision could mean less damage to healthy tissues and potentially fewer side effects. Researchers are excited about MMF because it offers a tailored approach that has been effective in other rheumatic diseases, suggesting it might provide better outcomes for patients with systemic sclerosis.

Research has shown that mycophenolate mofetil (MMF), which participants in this trial may receive, can help treat systemic sclerosis, particularly with lung and skin issues. Studies have found that MMF improves lung function and reduces skin thickening more effectively than treatments like methotrexate and steroids. Data from many patients indicate that MMF helps stabilize lung disease and improves skin symptoms over time. MMF proves particularly helpful for people with diffuse cutaneous systemic sclerosis, a severe form of the disease. Overall, MMF is considered a safe and effective option for managing symptoms of systemic sclerosis.¹²⁴⁶⁷
