Systemic Lupus Erythematosus (SLE), Lupus Arthritis, Laquinimod
Brief summary
The study aims to evaluate the safety and clinical effect of daily oral treatment with laquinimod capsules (0.5 milligrams \[mg\] and 1 mg) in participants with active lupus arthritis. Laquinimod is a novel immunomodulating drug which is currently in advanced stages of development by Teva Pharmaceuticals Ltd. for Multiple Sclerosis.
Interventions
Laquinimod will be administered per dose and schedule specified in the arm description.
Placebo matching to laquinimod will be administered per schedule specified in the arm description.

Eligibility
Inclusion criteria
* Participants diagnosed with SLE. * Participants with active lupus arthritis as evident by at least 4 tender and 4 swollen joints at screening and baseline visits, and moderate or severe arthritis with active synovitis in at least 1 joint, with some loss of functional range of movement present at screening and baseline visits.
Exclusion criteria
* The participant's estimated glomerular filtration rate (eGFR) was less than or equal to 30 milliliters (mL)/minute/1.73 square meter (m\^2), as calculated by the Modification of Diet in Renal Disease (MDRD) formula at the screening visit. * Participants with severe, unstable and/or progressive central nervous system (CNS) lupus and/or associated with significant cognitive impairment (upon the investigators' judgement). * Participants with a clinically significant or unstable medical or surgical condition that, in the investigator's opinion, would preclude safe and complete study participation. * Women who are pregnant or nursing or who intend to be during the study period. * Women of child-bearing potential who do not practice an acceptable method of birth control.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Adverse Events (AEs) | Baseline up to Week 16 | An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'. |
| Percent Change From Baseline in Swollen Joint Count at Week 12 | Baseline, Week 12 | The number of swollen joints was used to assess lupus arthritis activity. Joint swelling was defined as soft tissue swelling that was detectable along the joint margins. 66 joints were examined for swelling. These joints include the temporomandibular (n = 2), sternoclavicular (n =2), acromioclavicular (n = 2), shoulder (n = 2), elbow (n = 2), wrist (n = 2), metacarpophalageal (n= 10), interphalangeal of thumb (n = 2), distal interphalangeal (n = 8), proximal interphalangeal (n =8), knee (n = 2), ankle mortise (n = 2), ankle tarsus (n = 2), metatarsophalangeal (n = 10), interphalangeal of great toe (n = 2), and proximal/distal interphalangeal of the toes (n = 8). |
| Percent Change From Baseline in Tender Joint Count at Week 12 | Baseline, Week 12 | The number of tender joints was used to assess lupus arthritis activity. Joint tenderness was defined as the presence or absence of tenderness and/or pain in a joint at rest with pressure or on passive movement of the joint and joint manipulation. 68 joints were examined for tenderness. These joints include the temporomandibular (n = 2), sternoclavicular (n =2), acromioclavicular (n = 2), shoulder (n = 2), elbow (n = 2), wrist (n = 2), metacarpophalageal (n= 10), interphalangeal of thumb (n = 2), distal interphalangeal (n = 8), proximal interphalangeal (n =8), hip (n = 2), knee (n = 2), ankle mortise (n = 2), ankle tarsus (n = 2), metatarsophalangeal (n = 10), interphalangeal of great toe (n = 2), and proximal/distal interphalangeal of the toes (n = 8). |

Outcome results
Number of Participants With Adverse Events (AEs)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'.
Time frame: Baseline up to Week 16
Population: Safety analysis set included all randomized participants who received at least 1 dose of study drug. In this set, treatment was assigned based upon the treatment actually received regardless of the assigned treatment.
