Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - KZR-616

Experimental: KZR-616 45 mg + standard of care therapy (Phase 1b) - Dose escalation cohort of patients with SLE with and without nephritis to receive 45 mg dose level of KZR-616 in combination with standard of care therapy.

Two Phase 1b cohorts received 45 mg at some point during the study.

Cohort 1 received 45 mg zetomipzomib frozen maleate weekly for 13 weeks.

Cohort 2a followed a step-up dosing procedure. Patients received zetomipzomib frozen maleate, 30 mg weekly for 2 weeks, followed by 45 mg weekly for 2 weeks then followed by 60 mg weekly for 9 weeks.

KZR-616 was administered as a SC injection.

Experimental: KZR-616 60 mg + standard of care therapy (Phase 1b) - Dose escalation cohort of patients with SLE with and without nephritis to receive 60 mg dose level of KZR-616 in combination with standard of care therapy.

Four Phase 1b cohorts received 60 mg at some point during the study.

Cohort 2 received 60 mg zetomipzomib frozen maleate weekly for 13 weeks.

Cohorts 2a, 2b, and 2c all followed a step-up dosing procedure. Patients in Cohort 2a received zetomipzomib frozen maleate, 30 mg weekly for 2 weeks, followed by 45 mg weekly for 2 weeks then followed by 60 mg weekly for 9 weeks. Patients in Cohort 2b received zetomipzomib lyophile, 30 mg weekly for 1 week, followed by 60 mg weekly for 12 weeks. Patients in Cohort 2c (tolerability strategies cohort) received zetomipzomib lyophile, 30 mg weekly for 1 week, followed by 60 mg weekly for 12 weeks.

KZR-616 was administered as a SC injection.

Experimental: KZR-616 75 mg + standard of care therapy (Phase 1b) - Dose escalation cohort of patients with SLE with and without nephritis to receive 75 mg dose level of KZR-616 in combination with standard of care therapy.

One Phase 1b cohort received 75 mg at some point during the study.

Cohort 3 followed a step-up dosing procedure. Patients in Cohort 3 received zetomipzomib lyophile, 30 mg weekly for 1 week, followed by 75 mg weekly for 12 weeks.

KZR-616 was administered as a SC injection.

Experimental: KZR-616 60 mg + standard therapy (Phase 2) - 60 mg dose level of KZR-616 selected based on data from the phase 1b dose escalation and administered to patients with active lupus nephritis in combination with standard therapy including at least one immunosuppressive agent.

KZR-616 was administered as a SC injection weekly at a dose of 60 mg for 24 weeks (including a step-up from an initial Week 1 dose of 30 mg).
