A Non-Interventional Pilot Study Assessing Whether Lysyl Oxidase-like 2 (LOXL2) is Present in Subjects With Scleroderma

This study has been completed.

Gilead Sciences Identifier:
First received: June 5, 2013

To treat patients with scleroderma by blocking the expression of LOXL2. The investigators first need to confirm (through observation) that LOXL2 is overexpressed in disease.

Primary Outcome Measures:
  • Summarized the number and percentage of subjects with elevated LOXL2 levels [ Time Frame: Baseline ]

Biospecimen Retention:   Samples Without DNA
  • 5 mL blood draw for LOXL2 testing
  • 2 Punch Skin Biopsies (one near the scleroderma lesion, the other from normal skin)

Enrollment: 29

Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Limited Scleroderma
Diffuse Scleroderma

Detailed Description:
Scleroderma is a chronic skin-hardening disease. There are two types of scleroderma. The first type is called limited cutaneous scleroderma, where disrupted blood flow causes skin discoloration and sometimes patients experience high blood pressure in their arteries. The second type is called diffuse cutaneous scleroderma and it is much more aggressive, affecting a larger area of skin causing organ damage. This study will determine if the disease is associated with an elevated expression of LOXL2 levels in tissue samples from patients.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Adult subjects with documented diagnoses of scleroderma will be enrolled into one of two cohorts, depending upon the subject's diagnosis

Inclusion Criteria:

  • Over 18 years of age
  • Documented diagnosis of scleroderma
  • Willing and able to provide written informed consent

Exclusion Criteria:

  • Use of experimental therapies within 28 days prior to Screening.
  • Aspirin use > 81 mg daily within 1 week prior to Screening.
  • Any lab abnormality or concurrent medical condition that, in the opinion of the investigator would make the patient ineligible for the study
