Outcomes

Primary Outcome Measures

Annualized Slope of Change in Total Kidney Volume (TKV) From Baseline to Month 18: Stage 1
Total kidney volume is a measure for assessing disease progression in participants with ADPKD, a prognostic biomarker of renal function decline and progression to end-stage renal disease. Kidney volume was assessed using magnetic resonance imaging (MRI). The annualized slope of change in TKV (in percentage [%] per year) in each treatment group was obtained from the back-transformation of the mean slope of log10-transformed TKV obtained from the linear mixed effect model. The model included fix effects of treatment (venglustat 15 mg, venglustat 8 mg or placebo), mayo imaging classification (as per randomization stratification factor: class 1C versus 1D versus 1E), time (as continuous variable in years), treatment * time interaction and mayo imaging classification * time interaction and included random intercept and slope.
Annualized Rate of Change in Estimated Glomerular Filtration Rate (eGFR) (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) From Baseline to Month 24: Combined Stage 1 and Stage 2
An eGFR was used to measure level of kidney function and determine the stage of kidney disease in ADPKD participants. Baseline eGFR was defined for each participant as the average of eGFR values assessed prior or equal to first dose of study drug or randomization for participants randomized and not exposed. Annualized rate of change in eGFR in each treatment group was obtained from the linear mixed effect model including the fixed categorical effects of treatment group (venglustat 15 mg, venglustat 8 mg or placebo), mayo imaging classification (as per interactive response technology [IRT]: 1C, 1D, 1E), time (as continuous variable in years), treatment-by-time, mayo imaging classification-by-time, and included random intercept and slope.

Secondary Outcome Measures

Annualized Rate of Change in Estimated Glomerular Filtration Rate (eGFR) From Baseline to Month 24: Stage 1
An eGFR was used to measure level of kidney function and determine the stage of kidney disease in ADPKD participants. Baseline eGFR was defined for each participant as the average of eGFR values assessed prior or equal to first dose of study drug or randomization for participants randomized and not exposed. Annualized rate of change in eGFR was obtained from the linear mixed effect model including the fixed categorical effects of treatment group, mayo imaging classification (as per IRT), time (as continuous variable in years), treatment-by-time, mayo imaging classification-by-time, and included random intercept and slope. Due to early termination of study for futility, the two-steps analysis initially planned was not applicable, then the annualized rate of change from baseline in eGFR in Stage 1 population were assessed using all data available up to database lock (i.e., including Month 24 assessment). As this is a slope, it allowed to have more data and to reduce variability.
Annualized Slope of Change in Total Kidney Volume (TKV) From Baseline to Month 18: Combined Stage 1 and Stage 2
Total kidney volume is a measure for assessing disease progression in participants with ADPKD, a prognostic biomarker of renal function decline and progression to end-stage renal disease. Kidney volume was assessed using MRI. The annualized slope of change in TKV (in % per year) in each treatment group was obtained from the back-transformation of the mean slope of log10-transformed TKV obtained from the linear mixed effect model. The model included fix effects of treatment (venglustat 15 mg, venglustat 8 mg or placebo), mayo imaging classification (as per randomization stratification factor: class 1C versus 1D versus 1E), time (as continuous variable in years), treatment * time interaction and mayo imaging classification * time interaction and included random intercept and slope.
Change in Pain Severity as Measured by Brief Pain Inventory-Short Form (BPI-SF)-Item 3 Scale Score From Baseline to Month 18: Stage 1
The BPI-SF is a validated, self-administered questionnaire designed to measure a participant's perceived level of pain. The BPI-SF consisted of 15 items that use a numeric rating scale (NRS) to assess pain severity and pain interference in the past 24 hours and the past week. BPI-SF Item 3 asks participants to "Please rate your pain by marking the box beside the number that best describes your pain at its worst in the past 24 hours." The NRS ranged from 0 (no pain) to 10 (worst imaginable pain), where higher scores indicates greater intensity of pain. Least-squares (LS) means, and standard errors (SE) were estimated from mixed-effect model with repeated measures (MMRM) analysis.
Change in Pain Severity as Measured by Brief Pain Inventory-Short Form (BPI-SF)-Item 3 Scale Score From Baseline to Month 24: Combined Stage 1 and Stage 2
The BPI-SF is a validated, self-administered questionnaire designed to measure a participant's perceived level of pain. The BPI-SF consisted of 15 items that use a NRS to assess pain severity and pain interference in the past 24 hours and the past week. BPI-SF Item 3 asks participants to "Please rate your pain by marking the box beside the number that best describes your pain at its worst in the past 24 hours." The NRS ranged from 0 (no pain) to 10 (worst imaginable pain), where higher scores indicate greater intensity of pain. LS means and SE were estimated from MMRM analysis.
Change in Fatigue Severity as Measured by Brief Fatigue Inventory (BFI-SF)-Item 3 Scale Score From Baseline to Month 18: Stage 1
The BFI-SF is a 10-item, validated, self-administered questionnaire that was originally developed to assess fatigue severity. The 10-items were measured on a 0-10 scale, with 0 being 'does not interfere' and 10 being 'completely interferes.' BFI - Item 3 asks participants to 'Please rate your fatigue (weariness, tiredness) by circling the one number that best describes your worst level of fatigue during the past 24 hours. The NRS ranged from 0 (no fatigue) to 10 (worst imaginable fatigue). Higher global scores were associated with more severe fatigue. LS means and SE were estimated from MMRM analysis.

The Beck Depression Inventory-II (BDI-II) is a 21-item questionnaire used to assess depression. Most items are rated on a 4-point scale from 0 to 3, and a few items are rated on a 7-point scale. Individual item scores are added to get a total BDI-II score from 0 to 63. The higher the total score, the more severe the depression, and the lower the total score, the less severe the depression.
Number of Participants With Worsening Lens Opacity From Baseline During the Treatment-emergent Period: Combined Stage 1 and Stage 2
Worsening of lens opacity classification system (LOCS) III score or World Health Organization (WHO) grade in nuclear opacification, cortical opacification and posterior subcapsular opacification were assessed for 'Any eye', 'Unilateral' and 'Bilateral' separately. A participant could be counted in all the 3 categories. In each category, the worst case was taken into account. To be evaluable for 'Any', a participant had to have at least one eye evaluable, whereas, for 'Unilateral' and 'Bilateral', a participant had to have both eyes evaluable. Therefore, the sum of 'Unilateral' + 'Bilateral' is not necessarily equal to 'Any' in the below table. The difference observed in 'Nuclear Opacification' in 15 mg group, comes from that 1 participant who had Unilateral worsening at a given visit and a Bilateral worsening at another visit. Therefore, this participant was counted as 'Unilateral', 'Bilateral' and counted only once in 'Any'. Results are based on the TE period.

Primary Outcome Measure Information:
Title
Annualized Slope of Change in Total Kidney Volume (TKV) From Baseline to Month 18: Stage 1
Description
Total kidney volume is a measure for assessing disease progression in participants with ADPKD, a prognostic biomarker of renal function decline and progression to end-stage renal disease. Kidney volume was assessed using magnetic resonance imaging (MRI). The annualized slope of change in TKV (in percentage [%] per year) in each treatment group was obtained from the back-transformation of the mean slope of log10-transformed TKV obtained from the linear mixed effect model. The model included fix effects of treatment (venglustat 15 mg, venglustat 8 mg or placebo), mayo imaging classification (as per randomization stratification factor: class 1C versus 1D versus 1E), time (as continuous variable in years), treatment * time interaction and mayo imaging classification * time interaction and included random intercept and slope.

Title
Annualized Rate of Change in Estimated Glomerular Filtration Rate (eGFR) (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) From Baseline to Month 24: Combined Stage 1 and Stage 2
Description
An eGFR was used to measure level of kidney function and determine the stage of kidney disease in ADPKD participants. Baseline eGFR was defined for each participant as the average of eGFR values assessed prior or equal to first dose of study drug or randomization for participants randomized and not exposed. Annualized rate of change in eGFR in each treatment group was obtained from the linear mixed effect model including the fixed categorical effects of treatment group (venglustat 15 mg, venglustat 8 mg or placebo), mayo imaging classification (as per interactive response technology [IRT]: 1C, 1D, 1E), time (as continuous variable in years), treatment-by-time, mayo imaging classification-by-time, and included random intercept and slope.

Title
Annualized Rate of Change in Estimated Glomerular Filtration Rate (eGFR) From Baseline to Month 24: Stage 1
Description
An eGFR was used to measure level of kidney function and determine the stage of kidney disease in ADPKD participants. Baseline eGFR was defined for each participant as the average of eGFR values assessed prior or equal to first dose of study drug or randomization for participants randomized and not exposed. Annualized rate of change in eGFR was obtained from the linear mixed effect model including the fixed categorical effects of treatment group, mayo imaging classification (as per IRT), time (as continuous variable in years), treatment-by-time, mayo imaging classification-by-time, and included random intercept and slope. Due to early termination of study for futility, the two-steps analysis initially planned was not applicable, then the annualized rate of change from baseline in eGFR in Stage 1 population were assessed using all data available up to database lock (i.e., including Month 24 assessment). As this is a slope, it allowed to have more data and to reduce variability.

Annualized Slope of Change in Total Kidney Volume (TKV) From Baseline to Month 18: Combined Stage 1 and Stage 2
Description
Total kidney volume is a measure for assessing disease progression in participants with ADPKD, a prognostic biomarker of renal function decline and progression to end-stage renal disease. Kidney volume was assessed using MRI. The annualized slope of change in TKV (in % per year) in each treatment group was obtained from the back-transformation of the mean slope of log10-transformed TKV obtained from the linear mixed effect model. The model included fix effects of treatment (venglustat 15 mg, venglustat 8 mg or placebo), mayo imaging classification (as per randomization stratification factor: class 1C versus 1D versus 1E), time (as continuous variable in years), treatment * time interaction and mayo imaging classification * time interaction and included random intercept and slope.

Change in Pain Severity as Measured by Brief Pain Inventory-Short Form (BPI-SF)-Item 3 Scale Score From Baseline to Month 18: Stage 1
Description
The BPI-SF is a validated, self-administered questionnaire designed to measure a participant's perceived level of pain. The BPI-SF consisted of 15 items that use a numeric rating scale (NRS) to assess pain severity and pain interference in the past 24 hours and the past week. BPI-SF Item 3 asks participants to "Please rate your pain by marking the box beside the number that best describes your pain at its worst in the past 24 hours." The NRS ranged from 0 (no pain) to 10 (worst imaginable pain), where higher scores indicates greater intensity of pain. Least-squares (LS) means, and standard errors (SE) were estimated from mixed-effect model with repeated measures (MMRM) analysis.

Number of Participants With Worsening Lens Opacity From Baseline During the Treatment-emergent Period: Combined Stage 1 and Stage 2
Description
Worsening of lens opacity classification system (LOCS) III score or World Health Organization (WHO) grade in nuclear opacification, cortical opacification and posterior subcapsular opacification were assessed for 'Any eye', 'Unilateral' and 'Bilateral' separately. A participant could be counted in all the 3 categories. In each category, the worst case was taken into account. To be evaluable for 'Any', a participant had to have at least one eye evaluable, whereas, for 'Unilateral' and 'Bilateral', a participant had to have both eyes evaluable. Therefore, the sum of 'Unilateral' + 'Bilateral' is not necessarily equal to 'Any' in the below table. The difference observed in 'Nuclear Opacification' in 15 mg group, comes from that 1 participant who had Unilateral worsening at a given visit and a Bilateral worsening at another visit. Therefore, this participant was counted as 'Unilateral', 'Bilateral' and counted only once in 'Any'. Results are based on the TE period.
Time Frame
From the first IMP administration up to the last IMP administration in EFC15392 study + 30 days (i.e., up to 25 months) or up to the first visit in LTS15823 study, whichever comes earlier
