Study to Evaluate the Safety and Efficacy of Filgotinib and Lanraplenib in Adults With Lupus Membranous Nephropathy (LMN)
Lupus Membranous Nephropathy
About this trial
This is an interventional treatment trial for Lupus Membranous Nephropathy
Eligibility Criteria
Key Inclusion Criteria:
- Kidney biopsy within the 36 months prior to screening with a histologic diagnosis of LMN (International Society of Nephrology [ISN] and the Renal Pathology Society [RPS] 2003 classification of lupus nephritis), either Class V alone, or Class V in combination with Class II.
- Urine protein excretion ≥ 1.5 grams per day
- Estimated glomerular filtration rate (eGFR) ≥ 40 mg/min/1.73m^2 based on the modification of diet in renal disease (MDRD) formulation at screening
- No evidence of active or latent tuberculosis (TB) as assessed during screening
Key Exclusion Criteria:
Prior treatments as follows:
- Previous treatment with a janus kinase (JAK) inhibitor within 3 months of Day 1
- Use of rituximab or other selective B lymphocyte depleting agents (including experimental agents) within 6 months of Day 1. Enrollment is permitted if the last dose was given > 6 months and CD19-positive B cells are detectable at Screening.
- Use of any concomitant prohibited medications as described in the protocol
Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Filgotinib 200 mg to Lanraplenib 30 mg
Participants receive lanraplenib 30 mg tablet + filgotinib placebo tablet orally once daily for 16 weeks in Blinded Treatment Phase. Participants who achieve ≥ 35% reduction in urinary protein excretion from baseline continue to receive same blinded study treatment for additional 16 weeks. Participants who did not achieve a ≥ 35% reduction in urinary protein excretion will switch treatment. After 32 weeks of blinded treatment, participants who have ≥ 35% reduction in urinary protein excretion from baseline continue their assigned blinded treatment for additional 20 weeks in Extended Blinded Treatment Phase.

At Week 16, participants who do not achieve a ≥ 35% reduction in urinary protein excretion from baseline to Week 16 switch treatment and receive filgotinib 200 mg + lanraplenib placebo for additional 16 weeks. At Week 32, participants who do not achieve a ≥ 35% reduction in urinary protein excretion from Week 16 to Week 32 can continue whichever treatment that lead to the greatest reduction in urinary protein excretion, or either treatment per investigator's discretion for additional 20 weeks in Extended Blinded Treatment Phase.
At Week 16, participants who do not achieve a ≥ 35% reduction in urinary protein excretion from baseline to Week 16 switch treatment and receive lanraplenib 30 mg + filgotinib placebo for additional 16 weeks.
