A Study of KK4277 in Healthy Volunteers and Patients With Systemic Lupus Erythematosus and Cutaneous Lupus Erythematosus

Study to Evaluate the Safety, PK, PD, and Efficacy of PRX-102 in Japanese Patients With Fabry Disease

Investigators are doing this study to find out if treatment with pegunigalsidase alfa will prevent or reduce the development of health problems caused by Fabry disease and thereby improve patients' health and quality of life. pegunigalsidase alfa (PRX-102) is a drug made using genetic engineering techniques and manufactured using cultured tobacco cells. It is given by intravenous infusion every 2 weeks, at a dosage of 1 milligram per kilogram (mg/kg) of body weight. The study consists of a main study that is divided into two stages, each of which will last one year, followed by an optional extension study. In the optional extension stage, the participants may receive PRX-102 intravenous infusion every 2 weeks, at a dosage of 1 milligram per kilogram (mg/kg) of body weight or every 4 weeks at a dosage of 2 milligrams per kilogram (mg/kg) of body weight. There are three groups (cohorts) in this study, with adults enrolled in either Cohort A or B and adolescents in Cohort C. Whether an adult is assigned to Cohort A or Cohort B depends on their kidney function and treatment history. This study will start with a screening visit of up to 4 weeks. It will be followed up by infusion visits every 2 weeks or 4 weeks. For subjects not continuing in the extension stage, a follow-up call is to be made 30 days after the last study drug infusion.
