RUBY-3 Clinical Study

Lupus Nephritis

RUBY-3 is a phase 1/2 clinical study that is being conducted to determine if an investigational drug called povetacicept is safe and beneficial for people with lupus-related kidney disease (lupus nephritis) whose disease is not currently well controlled with standard medication(s).

All participants will receive povetacicept. Povetacicept is administered by injection under the skin.

Do you have lupus nephritis?

RUBY-3 is being conducted to determine if a new investigational drug, povetacicept, is safe and potentially beneficial for people with lupus nephritis.

Investigational means that povetacicept is still being evaluated and is not approved by health authority (e.g., the United States Food and Drug Administration (FDA)) for lupus nephritis or another condition.

Additional information is available at RUBY-3 ClinicalTrials.gov.

Who can join RUBY-3?

  • 18 years of age or older
  • have lupus nephritis that is confirmed by a biopsy
  • currently have active lupus nephritis despite receiving standard study treatment(s)
