  •  Atopic Dermatitis

    • A study for patients with moderate to severe atopic dermatitis (or eczema). There are more than 3 million cases per year in the US and some may see no relief from topical treatments alone. Symptoms may include inflamed, rough, itchy, or cracked skin. This issue can further lead into complications like skin infections and sleep issues. We are happy to provide this clinical research option to our patients and serve as an ancillary service at Austin Regional Clinic.


  •  C-Diffense Study

    • Vaccine study aimed to prevent clostridium difficile, or C. diff, infections. The study is enrolling people over age 50 who are at high risk of catching C. diff, but have no prior history of C. diff infection.


  • C-Diffense Vaccine

    • Diff Vaccination study, participants will be randomly assigned in parallel in a 1:1 ratio to receive C difficile vaccine (200µg total toxoid) at months 0, 1, and 6 (3-dose group) or at months 0 and 6 (2-dose group). The participants in the 2-dose group will receive placebo (saline) at Month 1.

    Sponsor: Exact Sciences Corporation Sponsor Link

  •  Melanoma

    • A biomarker is an indicator that can be found in blood, stool, urine or other bodily fluids and tissues that may show certain diseases. If accurate, biomarkers can be found for diseases, such as cancer, and could lead to earlier and less invasive discovery. The purpose of this opportunity is to study blood samples to detect biomarkers that could be used to improve melanoma detection. 

  •  Melanoma Blood Sample Collection

    • The primary objective of this study is to obtain de-identified, clinically characterized, whole blood specimens from subjects with untreated melanoma to evaluate biomarkers associated with cancer as potential targets for diagnostic assays and to support subsequent assay development activities.


  •  Pediatric ASD Diagnosis

    • Autism Spectrum Disorder (ASD) is a developmental disorder that affects communication and behavior. As of now there is a guide created by the American Psychiatric Association to help health care professionals diagnose ASD. This test is performed in a secondary care setting and can take several hours to administrate. However, it can still be difficult to diagnose since there’s no defined test such as a blood test.
