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.

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
Genders Eligible for Study:   Both
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
