Brief Summary
This study will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and efficacy of KP104 in participants with systemic lupus erythematosus (SLE)-Thrombotic microangiopathy (TMA). The study consists of 2 parts: Part 1 (Dose Optimization) and Part 2 (Proof of Concept). All participants will receive KP104 in combination with standard of care (SOC) for SLE-TMA.

Outcome Measures
Primary Outcomes (3)
Parts 1 and 2: Number of participants with Treatment-emergent adverse events (TEAEs), treatment-emergent serious adverse events (TESAEs) and Adverse events of special interest (AESIs)
Up to 24 weeks
Part 2: Percent change from Baseline in platelet count
Baseline (Day 1) and up to Week 12
Part 2: Percent change from Baseline in serum lactate dehydrogenase (LDH) levels
Baseline (Day 1) and up to Week 12
Study Arms (4)
Part 1: Dose Optimization Cohort 1, Dose 1
EXPERIMENTALParticipants will be administered with KP104 as a weekly maintenance dose for 24 Weeks. After the last participant completes 6 weeks of treatment, all available data, including safety, PK, PD, and modeling results, will be reviewed by the Internal Data Review Committee (IDRC) to determine Dosing Regimen 2
Part 1: Dose Optimization Cohort 2, Dose 2
EXPERIMENTALParticipants will be administered with KP104 dose regimen 2 for 24 Weeks. After the last participant completes 6 weeks of treatment, all available data, including safety, PK, PD, and modeling results, will be reviewed by the IDRC to determine Dosing Regimen 3.
Part 1: Dose Optimization Cohort 3, Dose 3
EXPERIMENTALParticipants will be administered with KP104 dose regimen 3 for 24 Weeks. After the last participant completes 6 weeks of treatment, all available data, including safety, PK, PD, and modeling results, will be reviewed by IDRC to determine the Optimal biologic dose (OBD) for Part 2.
Part 2: OBD Cohort, Dose 4
EXPERIMENTALParticipants will be administered with KP104 OBD for 24 Weeks.
Interventions
KP104 will be administered.
