This study is to investigate the efficacy of siplizumab in the treatment of Hidradenitis Suppurativa.
A 12-Month, Open-Label Study Evaluating Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Siplizumab as Induction Therapy in Patients With Autoimmune Liver Diseases Undergoing Liver Transplantation (SET-SAIL)
There is a significant unmet need for safe and effective therapeutic approaches to prevent immune-mediated graft injury and its complications in liver transplant (LT) recipients with autoimmune liver disease (AILD) including autoimmune hepatitis and primary sclerosing cholangitis. Siplizumab is an anti-CD2 monoclonal antibody that has demonstrated a favorable safety profile of siplizumab in over 779 human subjects and has been shown to target memory T cells-a key driver in the immune processes surrounding rejection and autoimmunity post LT in AILD. The purpose of this pilot, open-label phase 1 study is to determine the safety of siplizumab for induction in patients with AILD undergoing LT. Up to eight (8) subjects will receive siplizumab 0.6 mg/kg/dose on the day of transplant (Day 0) and Day 4 post-transplant, for a total of two doses. All subjects will be followed in the study for 12 months post-LT.
A 52-week, Phase 1 Safety, Pharmacokinetic and Pharmacodynamic Trial of Siplizumab in Newly Diagnosed Adult Amyotrophic Lateral Sclerosis (ALS) Patients (AURORA)
The purpose of this study is to investigate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of TCD601 (siplizumab) in newly diagnosed adult ALS patients.
