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.

Systemic Sclerosis | Drug: Prednisolone 5 mg Drug: Placebo oral capsule; From August 2020 'no additional treatment' | Phase 2 |
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:
- Is moderate dose prednisolone effective in reducing pain, disability and skin thickening in patients with early diffuse scleroderma?
- 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.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 35 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Patients are allocated to received either prednisolone or matched placebo for the duration of the trial. The allocation is randomised 1:1. From August 2020: Under the open-label design, patients are allocated to receive prednisolone or no additional treatment. The randomisation allocation is 1:1. |
Masking: | Triple (Participant, Care Provider, Investigator) |
Masking Description: | Double-blind. The trial management team are blind to treatment allocation for the duration of the trial. The site research teams and patients are blind to treatment until code-break. At this point the on-site team and patient are unblind to allocation for continuing care. The site pharmacy personnel, PRedSS trial monitor and supervising statistician are unblind throughout. From August 2020: Open-Label - The patient, site research team and site pharmacy are unblind. The trial management team are unblind for patients recruited from August 2020 onwards but remain blind to patients randomised to trial under the double-blind design. The trial monitor and trial statistician continue to be unblind for all patients randomised to trial. |

Arm | Intervention/treatment |

Active Comparator: Prednisolone
Prednisolone 5mg enteric-coated tablets, over-encapsulated in a hard gelatine capsule and filled with lactose BP. The prednisolone will be self-administered, orally with water before or after a meal once a day. Dosing will be continuous for a total of 6 months. The total dose prescribed will be equivalent to approximately 0.3mg/kg/day. The minimum dose prescribed will be 10mg per day (2 capsules) and a maximum of 30mg per day (6 capsules). From August 2020: The prednisolone is no longer over-encapsulated. Prednisolone 5mg enteric-coated tablets will be prescribed and taken as above. |
Drug: Prednisolone 5 mg
5mg prednisolone, once a day for 6 months |
Placebo Comparator: Placebo oral capsule; From August 2020 - 'no additional treatment'
The placebo will be a hard gelatine capsule filled with lactose BP and identically matched to the prednisolone capsules. The placebo will be self-administered once a day, orally with water before or after a meal. Dosing will be continuous for a total of 6 months. From August 2020 - no placebo capsule will be administered. |
