About this study

Official title: Effect of Sildenafil on Digital Ulcers in Systemic Sclerosis

This is a pilot study analyzing the effect of sildenafil therapy on digital ulcers in systemic sclerosis. We want to analyze ulcer healing by measuring the size of digital ulcers and their count and analyze the effect of sildenafil on angiography.

Read the detailed description

INVESTIGATOR: Dr. Gabriela Riemekasten Anke Praast Prof. G. R. Burmester Prof. Falk Hiepe

OBJECTIVES:

Sildenafil is a very potent drug in the treatment of digital ulcers secondary to Raynaud´s phenomenon in patients with connective tissue diseases. Probably, sildenafil has a disease-modifying capability improving different signs of a disturbed regulation of vascular tone in connective tissue diseases. Sildenafil can be used over a long period without significant side effects in scleroderma patients and improves disease severity, life quality, and prognosis of patients with connective tissue diseases and secondary Raynaud's phenomenon.

SUBJECTS and CENTERS:

We want to study 10-15 patients with digital ulcers secondary to connective tissue diseases and which are refractory to other drugs, such as calcium channel blockers or iloprost. In this pilot study, patients are treated only in the Charité University Hospital.

INCLUSION/EXCLUSION CRITERIA

1 . Digital gangrene, ulcers in patients with severe secondary Raynaud's phenomenon

  1. Stable therapy with vasoactive drugs, such as calcium channel blockers, angiotensin inhibitors/AT II receptor antagonists or pentoxifyllin 4 weeks before and during the treatment with sildenafil.
  2. Unchanged immunosuppressive therapy 3 months before treatment with sildenafil
  3. No effect of prostacyclin treatment, contraindications for prostacyclins, or other reasons excluding this therapy

EXCLUSION CRITERIA:

  1. Therapy with iloprost during the last 4 weeks
  2. Sympathectomy during the last 4 weeks
  3. TIA, stroke, myocardial infarction during the last 6 months
  4. Instable angina pectoris
  5. Hemorrhagic diathesis, thrombocytic dysfunction, fibromuscular dysplasia
  6. Microangiopathic hemolytic anaemia
  7. Azotaemia
  8. Hypertonus not adjustable with diuretic, clonidine, ACE inhibitors/AT II antagonists, calcium channel blockers)
  9. Left ventricular ejection fraction< 20%
  10. Hypotonus < 80/40 mm Hg
  11. Positive pregnancy test
  12. History of cancer
  13. History of gastric/duodenic ulcers without endoscopic proof of complete healing
  14. Participation in other studies (currently or during the last 4 weeks)
  15. Abuse of alcohol or other drugs, smoker
  16. Cardiac failure, use of nitrates

STUDY DESIGN:

This is an open prospective pilot study of one centre determining the effect of a 6 month treatment of sildenafil in patients with acral ulcers in secondary Raynaud's phenomenon due to connective tissue diseases.

Drop out criteria's/ final points:

1 . Any change of the immunomodulating or suppressing therapy (e.g., treatment with cyclophosphamide because of an alveolitis; bolus of steroids > 30 mg/d).

  1. No response on the healing of ulcers after 4 weeks of treatment with sildenafil 3. Manifestation of new ulcers/necrosis under sildenafil 4. Escalation of medication with an vascular influence (calcium channel blockers, ACE inhibitors/AT II receptor blockers)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sildenafil therapy in people with Active Digital Ulcers, run by Charite University, Berlin, Germany at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Jan 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

healing of digital ulcer (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2009.
