- Brief Summary
Many patients with Scleroderma (Systemic sclerosis) experience damage to blood vessels, mainly to the small arteries. A common manifestation of this is Raynaud's phenomenon (fingers or toes turning white then blue in the cold) and digital ulcers (open sores on the fingertips). The purpose of this study is to see how effective the study drug Human Factor XIII Concentrate is in treating patients who have these and other common manifestation of Scleroderma. It will be given in addition to the accepted treatments used for this disease.
- Detailed Description
This is a phase II, double-blind, randomized, placebo-controlled study to investigate pharmacokinetics (PK), safety and efficacy of intravenous factor XIII treatment in patients with systemic sclerosis.
Scleroderma (Systemic sclerosis) is a multisystem rheumatic disease that is characterised by progressive vascular damage e.g Raynaud's phenomenon and digital ulcers and organ fibrosis e.g. skin thickening and pulmonary fibrosis.The disease is associated with significant morbidity and mortality and current therapeutic options are only partially effective, including Cyclophosphamide for skin or lung fibrosis and Bosentan which reduces but does not heal digital ulcers.
There is no cure available and there is therefore a high need for new therapeutic options.Administration of human Factor XIII (FXIII) concentrate in patients with scleroderma demonstrated promising results in the 1980s and 1990s . However these studies were not performed according to current Good Clinical Practice (GCP) guidelines and involved relatively small sample sizes.
This is a single site study, therefore all study participants will be seen at the Royal Free London National Health Service (NHS) Foundation Trust.Total study duration is 36 months and will involve 2 phases: an initial single dose, pharmacokinetic (PK) phase in 8 subjects over 6 weeks and a multiple dose, active treatment phase in 18 subjects over 24 weeks. During the treatment phase subjects will be randomized at 2:1 ratio to either FXIII or Placebo and will receive biweekly injection of either factor XIII Concentrate or placebo.

- Subjects will have serological status for hepatitis A and B assessed at screening.
- Patients who have given their free and informed consent. -≥ 18 years.
Participants must:
- Be willing to use an effective method of contraception (hormonal or barrier method of birth control; abstinence) from the time consent is signed until 6 weeks after treatment discontinuation (females of childbearing potential and males)
- Have a negative pregnancy test within 7 days prior to being registered for trial treatment (females of childbearing potential). NOTE: Subjects are considered not of child bearing potential if they are surgically sterile (i.e. they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are postmenopausal.

- Have a haemoglobin concentration ≤ 10 g/dL (≤ 100 g/L) at the Screening Visit.
- Have a history of left-sided heart disease and/or clinically significant cardiac disease, including but not limited to any of the following: aortic or mitral valve disease (stenosis or regurgitation) defined as more than minimum aortic insufficiency and more than moderate mitral regurgitation (stenosis or regurgitation≥ grade 1); pericardial constriction; restrictive or congestive cardiomyopathy; left ventricular ejection fraction ≤ 40 % by multiple gated acquisition scan (MUGA), angiography, or echocardiography; left ventricular shortening fraction ≤ 22 % by echocardiography; or symptomatic coronary disease with demonstrable ischemia.
- Have a history of malignancies within 5 years of Screening Visit with the exception of localized skin or cervical carcinomas.
- Have psychiatric, addictive, or other disorder that compromises the ability to give informed consent for participating in this study. This includes subjects with a recent history of abusing alcohol or illicit drugs.
