Phase 2
Terminated
Conditions
Lupus Erythematosus, Systemic
Interventions
Registration Number
NCT03407482
Lead Sponsor

Brief Summary

This Phase II, multicenter, open-label extension (OLE) study will evaluate the long-term safety and efficacy of GDC-0853 in participants with systemic lupus erythematosus (SLE) who have completed Study GA30044 (NCT02908100) up to 48 weeks.

Inclusion Criteria
  • Able to comply with the study protocol, in the investigator's judgment
  • Completion of Study GA30044 up to 48 weeks
  • Acceptable safety and tolerability during Study GA30044 as determined by the investigator
Exclusion Criteria
  • Met protocol-defined treatment-stopping criteria during Study GA30044
  • An adverse event in Study GA30044 that required permanent discontinuation of study drug
  • In the opinion of the investigator, any new, significant, uncontrolled comorbidity or new clinical manifestation (related to SLE or not) that requires medications not allowed in this protocol; or could put the participant at undue risk from a safety perspective
  • Any uncontrolled or clinically significant laboratory abnormality that would affect safety, interpretation of study data, or the participant's participation in the study in the opinion of the investigator in consultation with the Medical Monitor

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Adverse Events (AEs)Baseline up until 8 weeks after the last dose of study drug (up to 56 weeks)

An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An Adverse Event can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as Adverse Events.

Secondary Outcome Measures
NameTimeMethod
Area Under the Concentration-Time Curve From Time 0 to Time t (AUC0-t,ss) of GDC-0853 at Steady StatePre-dose (0 hour [hr]) at Weeks 0, 24, 48, at unscheduled or flare or early termination visit (up to Week 56)

Population PK model estimated AUC of GDC-0853 From Time 0 to Time t (AUC0-t) at steady-state. AUC was measured in Nanograms (ng) per millilitre(mL)\*hour (hr).

Systemic Lupus Erythematosus Responder-4 Index (SRI-4) up to Week 48Baseline up to Week 48

The Systemic Lupus Erythematosus Responder Index (SRI)-4 measures reduction in SLE disease activity and is a composite measure that includes the SLE Disease Activity Index (SLEDAI-2K), British Isles Lupus Activity Group (BILAG) 2004 and Physician Global Assessment. It is defined as: 1) Reduction of ≥4 points from baseline in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score; 2) no new British Isles Lupus Assessment Group (BILAG) A or no more than 1 new BILAG B disease activity scores and 3) no worsening (defined as an increase of ≥0.3 points \[10 mm\] from baseline) in the Physician's Global Assessment of Disease Activity. The score range is from 0 to 100, with higher scores indicating greater disease activity.

Minimum Plasma Concentration of GDC-0853 at Steady State (Ctrough,ss)Pre-dose (0 hr) at Weeks 0, 24, 48, at unscheduled or flare or early termination visit (up to Week 56)

Population PK model estimated minimal plasma concentration (Ctrough) of GDC-0853 at steady-state (ss).

Plasma Decay Half-Life of GDC-0853 at Steady State (t1/2,ss)Pre-dose (0 hr) at Weeks 0, 24, 48, at unscheduled or flare or early termination visit (up to Week 56)

Population PK model estimated plasma decay half life of GDC-0853 at steady-state.

Apparent Oral Clearance of GDC-0853 at Steady State (CL/F,ss)Pre-dose (0 hr) at Weeks 0, 24, 48, at unscheduled or flare or early termination visit (up to Week 56)

Population PK model estimated apparent oral clearance of GDC-0853 at steady-state.
