Summary

This is a randomised placebo-controlled study of moderate dose prednisolone for 6 months in patients with early diffuse cutaneous systemic sclerosis (dcSSc). Seventy-two patients within 3 years of the onset of skin thickening will be recruited from 14 UK centres over 3 years. Co-primary end-points will be the Health Assessment Questionnaire Disability Index (HAQ-DI) and the modified Rodnan skin score (mRSS). Patients will be assessed 5 times: screening, baseline, 6 weeks, 3 and 6 months, with a code-break on exit from the study at 6 months. Please note: From August 2020, the trial was re-started following halt due to Covid-19 as open-label. The placebo arm is the 'no treatment' arm and there is no longer a code-break at study exit.

Detailed description

The study is a non-commercial phase II randomised, double-blind, placebo-controlled, multi-centre study to test moderate dose prednisolone versus placebo in patients with early diffuse cutaneous systemic sclerosis (dcSSc). Our aim is to investigate whether treatment with the steroid prednisolone is beneficial in patients with early diffuse cutaneous systemic sclerosis (also termed "scleroderma"). This is a controversial subject. Although it is very possible that prednisolone can help relieve the severe pain, itching, and disability (due to contractures and musculoskeletal involvement) of early diffuse scleroderma, doctors are often reluctant to prescribe prednisolone because of possible side effects, particularly an increased risk of serious kidney problems. Our proposed trial, treating patients with either prednisolone or placebo therapy for 6 months, should provide clinicians with a long awaited answer to the important clinical question: Can prednisolone be used as a therapy in this group of patients? The study, funded by Arthritis Research UK, aims to determine: 1. Is moderate dose prednisolone effective in reducing pain, disability and skin thickening in patients with early diffuse scleroderma? 2. Is moderate dose prednisolone a safe therapy in patients with early diffuse scleroderma (with particular reference to kidney function)? If the answer to both is 'yes', then prednisolone therapy will be much more widely prescribed for this patient group. The patient population will be selected from individuals with early dcSSc, as defined by skin involvement of less than 3 years, who are considered potentially able to benefit from this treatment. Following screening, to minimise bias, eligible patients will be randomised at the baseline visit to receive either daily moderate dose prednisolone (as determined by body weight) or a matched placebo. To further eliminate subjective and unrecognised bias both the research team and patients will be blind to the randomisation. A placebo control, as opposed to an active treatment control, will be administered. This is necessary as the study treatment is adjunctive to and not a substitute for any other therapies which may be prescribed, such as immunosuppressant therapies. Patients will attend on 5 occasions (screen, baseline, 6 weeks, 3 and 6 months). All patients will be considered off-study at the end of the 6 month visit whereupon the treatment code will be broken. At each visit a number of measurements will be taken including functional ability, degree of skin involvement (skin score), mood and kidney function. This will allow us to determine whether 'active' (prednisolone) therapy is effective and free from serious side-effects. Please note: from August 2020, due to Covid-19 the trial was re-designed and re-started following trial halt as open-label. A placebo is no longer required. The aims, primary outcome measures and number of visits remain unchanged. However, to further mitigate the ongoing impact of Covid-19, the screen and baseline assessments may now be conducted at the same visit. Remote visits can also be carried out at 6 weeks and 6 months, if necessary.
