Leflunomide for Musculoskeletal GVHD After Allogeneic Stem Cell Transplant
Pilot Study of Leflunomide as First Line Therapy for Musculoskeletal GVHD
Graft versus host disease (GVHD) is a well-known complication of allogeneic transplant. In GVHD, the cells of the donor attack the patient's tissues and cause damage. It can affect any organ or system of the body. In a proportion of patients, it affects the joints and muscles. This is known as musculoskeletal GVHD. The standard treatment of musculoskeletal GVHD is steroids. However, these are usually needed for prolonged periods, and cause a large number of additional problems in transplant patients.
Leflunomide is a drug which has been used for several years in diseases like rheumatoid arthritis (RA). RA is an auto-immune disorder. The biological mechanisms underlying RA and musculoskeletal GVHD are quite similar. Hence it is likely that leflunomide may work in musculoskeletal GVHD also. The investigator have previously used leflunomide in a few patients with musculoskeletal GVHD and have found it to be extremely effective. Also, it was very safe (unlike steroids). Yet another advantage is that it is fairly cheap.
The purpose of the current study is to study the efficacy and safety of leflunomide in patients with musculoskeletal GVHD in a prospective way.

Detaillierte Beschreibung
The curative potential of allogeneic hematopoietic stem cell transplantation (allo-HCT) is hampered by acute and chronic graft-versus-host disease (GVHD). Although chronic GVHD (cGVHD) can affect any organ / system in the body, commonly affected are skin, oral cavity, eyes, liver, joints and fascia, and lungs. Involvement of these can occur alone or concurrently, and these lead to a significant negative impact on the patient's quality of life. Musculoskeletal involvement in chronic GVHD (mGVHD) can have varied presentations like fasciitis, myositis, arthritis, etc. The basic pathogenesis of mGvHD closely mimics autoimmune disorders like rheumatoid arthritis, systemic sclerosis, systemic lupus, etc.
The treatment goals of mGvHD include improvement or stabilisation of manifestations, limitation of long-term treatment related toxicities, improvement in functional capacity and quality of life. Corticosteroids, the standard frontline treatment, are typically administered for a median of 2 to 3years, leading to substantial morbidity. An effort to decrease corticosteroid doses has led to their use in combination with other drugs, such as cyclosporine, tacrolimus, sirolimus, mycophenolate mofetil, rituximab, etanercept, ruxolotinib, imatinib, ibrutinib, ECP (extra corporeal photopheresis), methotrexate etc, in frontline or second-line settings. All these drugs have been used with far and few responses but with significant treatment related toxicity and costs. As far as musculoskeletal GVHD is concerned, the British guidelines recommend corticosteroids as first line treatment and rituximab as second line option. However, the morbidity associated with long term steroid use warrants a quest for use of non-steroid therapies to be used in 1st line setting for chronic GVHD.
Leflunomide has been used in rheumatoid arthritis. At our centre, the investigator have previously used leflunomide for patients with musculoskeletal GVHD and found it to be effective and safe. Leflunomide is relatively cheap and potentially more effective compared to other more expensive alternatives. If proven to be effective in a larger cohort of patients, this drug could become the standard first line agent in this setting.
With this, the investigator have planned to carry out this study to assess the efficacy of leflunomide in musculoskeletal GVHD post allogeneic stem cell transplant.
