NCT05504187

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

EXPERIMENTAL

Participants 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

Drug: KP104

Part 1: Dose Optimization Cohort 2, Dose 2

EXPERIMENTAL

Participants 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.

Drug: KP104

Part 1: Dose Optimization Cohort 3, Dose 3

EXPERIMENTAL

Participants 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.

Drug: KP104

Part 2: OBD Cohort, Dose 4

EXPERIMENTAL

Participants will be administered with KP104 OBD for 24 Weeks.

Drug: KP104
