|Condition or disease||Intervention/treatment||Phase|
|Systemic Lupus Erythematosus Lupus Erythematosus, Systemic||Drug: TAK-079 Drug: TAK-079 Placebo||Phase 1|
TAK-079 is being tested in a study population with moderate to severe SLE. This study will evaluate the safety and biologic activity of TAK-079 or matching placebo in combination with stable SLE background therapy.
The study will enroll approximately 24 participants across 3 sequentially enrolling cohorts. Each cohort will enroll 8 participants, where 6 participants will be assigned to TAK-079 injection, and 2 participants will be assigned to Placebo. Participants will receive TAK-079 or matching placebo in combination with principal investigator directed background therapy for SLE.
This multi-center trial will be conducted in the United States. Participants will make multiple visits to the clinic, and will be followed up for the safety assessment for the additional 12 weeks up to Week 24 after receiving their last dose of study drug. Based on the clinical assessments, participants may complete or may advance to long-term safety follow up period for an additional 12-week safety monitoring period up to Week 36.

- Number of Participants who Experience at Least one Treatment-emergent Adverse Event (TEAE) and Serious Adverse Event (SAE) [ Time Frame: Up to Week 36 ]
- Number of Participants With Grade 3 or Higher TEAEs [ Time Frame: Up to Week 36 ]The severity of TEAEs will be graded using National cancer institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.0 definitions of Grade 1 through Grade 5. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living. Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care activities of daily living. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.
- Percentage of Participants With Greater Than or Equal to (>=) 1 Adverse Event (AE) Leading to Treatment Discontinuation [ Time Frame: Up to Week 36 ]
- Cmax: Maximum Observed Plasma Concentration for TAK-079 [ Time Frame: Day 1 pre-dose and at multiple time points (up to 168 hours) post-dose; Day 22 pre-dose and at multiple time points (up to 108 hours) post-dose; Days 43 and 64 pre-dose and at multiple time points (up to 5 hours) post-dose ]
- AUClast: Area Under the Plasma Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for TAK-079 [ Time Frame: Day 1 pre-dose and at multiple time points (up to 168 hours) post-dose; Day 22 pre-dose and at multiple time points (up to 108 hours) post-dose; Days 43 and 64 pre-dose and at multiple time points (up to 5 hours) post-dose ]
- Number of Participants With Change From Baseline In Immune Cell Subsets [ Time Frame: Baseline up to Day 85 ]Immune cell subsets will include plasma cells, plasma blast (PBs), natural killer (NK) cells, B cells, T cells, monocytes, and total lymphocytes.
- Number of Participants With Change From Baseline in (Cluster of Differentiation 38) CD38 Expression Level and Receptor Occupancy [ Time Frame: Baseline up to Day 85 ]CD38 expression and receptor occupancy will be evaluated for plasma cells, PBs, NK cells, B cells, T cells, and monocytes.
- Change From Baseline in Cytokines Level [ Time Frame: Baseline up to Day 85 ]Cytokine measurements will be assessed from baseline at different timepoints for placebo and each TAK-079 dose level.
- Number of Participants With Positive Anti-drug Antibodies [ Time Frame: Baseline up to Day 85 ]
