Trial Outcomes & Findings for Efficacy and Safety Study of Abatacept to Treat Lupus Nephritis (NCT NCT01714817)

NCT ID: NCT01714817

Last Updated: 2021-02-26

Results Overview

Number of participants achieving CR was divided by the total number of participants in that arm and expressed as a percentage. CR defined as: eGFR is normal or no \<85% of the baseline; eGFR based on mean creatinine value from day 358 and 365. Proteinuria: UPCR\<0.5 mg/mg. Urine sediment: No cellular casts. Corticosteroid dose: Daily dose must be no \>10 mg prednisone or equiv. for at least 28 days prior to assessment. Participants with \>10mg/day prednisone or equivalent for non-renal disease within 28 days prior to day 365 will be imputed as having achieved CR if the following are true: Met all criteria for CR at day 337 and all criteria for CR except corticosteroid dose at day 365; Investigator confirms increase in steroid dose is not related to renal disease. Adjusted odds ratio is estimated from logistic regression model which includes treatment group, baseline ACEi/ARBs use (Yes/No), race (Asian/ Black/Caucasian/Other) and baseline UPCR as a continuous variable.

PRIMARY outcome

Timeframe: Day 365

Population: All randomized and treated participants

Number of participants achieving CR was divided by the total number of participants in that arm and expressed as a percentage. CR defined as: eGFR is normal or no \<85% of the baseline; eGFR based on mean creatinine value from day 358 and 365. Proteinuria: UPCR\<0.5 mg/mg. Urine sediment: No cellular casts. Corticosteroid dose: Daily dose must be no \>10 mg prednisone or equiv. for at least 28 days prior to assessment. Participants with \>10mg/day prednisone or equivalent for non-renal disease within 28 days prior to day 365 will be imputed as having achieved CR if the following are true: Met all criteria for CR at day 337 and all criteria for CR except corticosteroid dose at day 365; Investigator confirms increase in steroid dose is not related to renal disease.

Population: All randomized and treated participants with both post-baseline and baseline measurements

Adjusted mean change from baseline in British Isles Lupus Assessment Group (BILAG) score over time during Year 1 of the double-blind period based on a repeated measure mixed model and presented at each visit in the first 12-month of the double-blind period. BILAG index measures disease activity in different organs/systems separately. BILAG score is calculated for each of 9 systems depending on the clinical features present and whether they are new (4 points), worse (3 points), the same (2 points), improving (1 point) or not present (0 points) in the last 4 weeks compared with previously. BILAG "A" represents the presence of serious features of lupus. BILAG "B" represents more moderate features of the disease. BILAG "C" includes only mild symptomatic features. BILAG "D" represents prior activity with no current symptoms due to active lupus. BILAG "E" represents an organ that has never been involved. Overall BILAG score ranges from 0-108, with higher scores reflecting a worse outcome.

All AEs were coded and grouped into preferred terms (PT) by system organ class (SOC), using the Medical Dictionary for Regulatory Activities (MedDRA, version 21.0). Investigators determined the intensity of each AE as mild, moderate, severe, or very severe and assessed the relationship to study drug.

Sustained change to no response is defined as going from CR (or PR) to NR and remaining in NR for at least 2 consecutive visits; visits should be approximately 4 weeks apart.

BILAG index measures and reports disease activity in different organs/systems separately. The BILAG score is calculated for each of nine systems depending on the clinical features present and whether they are new (4 points), worse (3 points), the same (2 points), improving (1 point) or not present (0 points) in the last 4 weeks compared with previously. A BILAG "A" represents the presence of one or more serious features of lupus. A BILAG "B" represents more moderate features of the disease. A BILAG "C" includes only mild symptomatic features. A BILAG "D" represents only prior activity with no current symptoms due to active lupus. A BILAG "E" represents an organ that has never been involved. Overall BILAG score ranges from 0-108, with higher scores reflecting a worse outcome.

All AEs were coded and grouped into preferred terms (PT) by system organ class (SOC), using the Medical Dictionary for Regulatory Activities (MedDRA, version 21.0). Investigators determined the intensity of each AE as mild, moderate, severe, or very severe and assessed the relationship to study drug.

Lupus treatment failure is defined as any of the following: Death, unless due to physical trauma or violence; Renal Flare; sustained doubling of creatinine from baseline (greater of Screening or Study Day 1 value); initiation of rescue therapy for treatment of active lupus nephritis after Study Week 20. Overall treatment failure is defined as lupus treatment failure plus discontinuation of study drug for any reason except death due to physical trauma or violence, pregnancy or administrative decision by Sponsor.

First treatment failure (or Lupus treatment failure) is defined as any of the following: Death, unless due to physical trauma or violence; Renal Flare; sustained doubling of creatinine from baseline (greater of Screening or Study Day 1 value); initiation of rescue therapy for treatment of active lupus nephritis after Study Week 20. Overall treatment failure is defined as lupus treatment failure plus discontinuation of study drug for any reason except death due to physical trauma or violence, pregnancy or administrative decision by Sponsor. The hazard ratio is estimated using the Cox proportional hazards model which includes treatment group, stratification variables (baseline ACEis/ARBs use, RACE) and baseline UPCR. The estimate of median time is based on Kaplan-Meier analysis

Timeframe: Day 729

Population: All randomized and treated nephrotic participants, as observed, calculated per modified criteria (UPCR and eGFR only). Nephrotic is defined as screening UPCR \>= 3.0mg/mg (\>=339mg/mmol)

Number of participants achieving CR was divided by total participants in that arm, expressed as a percentage. CR is defined the following criteria: eGFR is normal or no \<85% of the baseline value; eGFR is based on mean creatinine value from day 358 and 365. Proteinuria: UPCR\<0.5 mg/mg. Urine sediment: No cellular casts. Corticosteroid dose: Daily dose must be no \>10 mg prednisone or equivalent for at least 28 days prior. Subjects with \>10mg/day prednisone or equivalent for non-renal disease within 28 days prior to day 365 will be imputed as CR if the following are true: Met all criteria for CR at day 337 and all criteria for CR except corticosteroid dose at day 365; Investigator confirms increase in steroid dose is not related to renal disease. Adjusted odds ratio is estimated from logistic regression model which includes treatment group, baseline ACEi/ARBs use, race and baseline UPCR as a continuous variable.
