Brief Summary:
The purpose of this study is to characterize the safety and tolerability of ixazomib when administered as multiple oral doses at escalating dose levels in participants with lupus nephritis.

Condition or disease Intervention/treatment Phase
Lupus Nephritis Drug: Ixazomib Drug: Placebo Phase 1

Detailed Description:

The drug being tested in this study is called ixazomib. Ixazomib is being tested to find a safe and well tolerated dose in participants with lupus nephritis. This study will look at side effects and lab results in participants who take ixazomib, along with the characterization of its pharmacokinetics (PK). This study is designed as a randomized, sequential-panel, multiple rising dose study.

The study will enroll approximately 40 participants. The study population will consist of 4 Cohorts. At least 5 participants (4:1 active:placebo) will be recruited into the 0.5 mg dose group (Cohort A), at least 5 participants (4:1 active:placebo) in the 2.0 mg dose group (Cohort B), 8 participants (6:2 active:placebo) in the 3.0 mg dose group (Cohort C), and 8 participants (6:2 active:placebo) in the 4.0 mg dose group (Cohort D). Participants in each Cohort will be asked to take one capsule on Days 1, 8 and 15 in 28-day cycle, for 3 cycles. PK samples will be collected to measure concentrations of ixazomib. The starting dose in Cohort A will be 0.5 mg followed by administrations of 2, 3 and 4 mg in subsequent cohorts.

This multi-center trial will be conducted in the United States and Europe. The overall time to participate in this study is up to 196 days. Participants will make 19 visits to the clinic during the treatment period and will make follow-up visits monthly for 3 months for follow-up assessments.
