Efficacy and Safety in Chinese Patients with Immunoglobulin a Nephropathy (IgAN) Who Have Completed Study Nef-301
- Conditions
- Primary Immunoglobulin a Nephropathy (IgAN)
- Interventions
- Drug: Nefecon
- Registration Number
- NCT05534919
- Lead Sponsor
- Everest Medicines (Singapore) Pte. Ltd.
- Brief Summary
This is a Phase 3b, multicenter, open-label extension (OLE) study to evaluate the efficacy and safety of Nefecon treatment in Chinese patients who have completed Nef-301 and continue to be treated with a stable dose of Renin-angiotensin system (RAS) inhibitor therapy (Angiotensin-converting enzyme inhibitors (ACEIs) and/or Angiotensin II type I receptor blockers (ARBs).
- Detailed Description
This is a Phase 3b, multicenter, open-label extension (OLE) study to evaluate the efficacy and safety of Nefecon treatment in Chinese patients with Immunoglobulin A nephropathy (IgAN) who have completed Nef 301 study and continue to be treated with a stable dose of RAS inhibitor therapy (ACEIs and/or ARBs).
During Study open-label extension (OLE) study, patients will receive Nefecon for a 9-month period. The patient will come for a follow-up visit at 12 months after first dose.
