Other Studies

Viral Infections in Non-immunocompromised Patients

This study seeks patients who are thought to have normal immune systems, but who have been diagnosed with a viral infection that is unusually severe, prolonged, or persistent. This study will evaluate the participants’ immune systems to determine why the infection developed.

Rare Diseases

Rituximab for Treatment of Systemic Sclerosis-Associated Pulmonary Arterial Hypertension (SSc-PAH)

This trial will determine if rituximab, an immunotherapy, has a marked beneficial effect on clinical disease progression, with minimal toxicity, in patients with SSc-PAH when compared to placebo.
