Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Lumasiran (ALN-GO1): 1.0 mg/kg QM or 3.0 mg/kg Q3M

Participants enrolling from study 001B (NCT02706886), received lumasiran, subcutaneous (SC) injection, at a starting dose of 1.0 milligrams per kilograms (mg/kg) once monthly (QM) or 3.0 mg/kg once every 3 months [Q3M]) from Day 1 up to a maximum of Month 6. By Month 6, all participants were approved to change dose and/or dosing regimen to receive lumasiran, SC injection at a dose of 3.0 mg/kg, Q3M, up to Month 51 of the treatment period.

All 3 participants who began treatment at 1 mg/kg QM transitioned to 3 mg/kg Q3M regimen by Month 6. As the cumulative dose administered over 6 months was the same for both 1 mg/kg QM & 3 mg/kg Q3M, these participants were pooled into one arm as recommended by the Safety Review Committee (SRC).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With at Least One Adverse Event (AE)
Time Frame: Baseline (Day -1) up to 54 months
AE is any untoward medical occurrence in a participant or clinical investigational subject administered a medicinal product and which does not necessarily have a causal relationship with this treatment. Safety analysis set included all participants who received any amount of study drug.
Baseline (Day -1) up to 54 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in 24-hour Urinary Oxalate Corrected for Body Surface Area (BSA) at 54 Months
Time Frame: Baseline (Day -1) up to 54 months
Oxalate produced by the liver is the key toxic metabolite that drives disease pathology in participants with primary hyperoxaluria type 1 (PH1). The risk of disease complications increase continuously as oxalate levels increase. 24-hour urinary oxalate (millimole [mmol]/ 24 hour [h]/1.73 meters squared [m^2]) corrected for BSA at each visit per participant was calculated as follows: [Urine oxalate concentration (micromole per liter [umol/L])/1000 (umol/mmol)]*[24hour urine volume (mL)/1000 (mL/L)]* [24 hours/actual collection hours]*1.73/(BSA). Baseline was the derived baseline value from the lumasiran treated period of Study ALN-GO1-001. A negative change from baseline indicated a favorable outcome. PD analysis set included all participants who received any amount of study drug and who had at least 1 post-dose urine sample for PD. Overall number of participants analyzed are the number of participants with data available for analysis.
Baseline (Day -1) up to 54 months
Change From Baseline in 24-hour Urinary Oxalate:Creatinine Ratio at 54 Months
Time Frame: Baseline (Day -1) up to 54 months
Baseline is the derived baseline value from the lumasiran treated period of Study ALN-GO1-001. A negative change from baseline indicates a favorable outcome. PD analysis set included all participants who received any amount of study drug and who had at least 1 post-dose urine sample for PD.
Baseline (Day -1) up to 54 months
Change From Baseline in Estimated Glomerular Filtration Rate (eGFR) at 54 Months
Time Frame: Baseline (Day -1) up to 54 months
Baseline was defined as the last measurement prior to the first dose of lumasiran in the ALN-GO1-001 study. eGFR was calculated based on the Modification of Diet in Renal Disease (MDRD) formula for participants >=18 years of age at enrollment and the Schwartz Bedside formula for participants <18 years of age at enrollment. eGFR based on MDRD formula was calculated as follows: eGFR (mL/min/1.73 m^2) = 175 × (serum creatinine {SCr} [μmol/deciliter(dL)]/88.4)-1.154 × (age)-0.203 × (0.742, if female), or × (1.212, if African American) and based on Schwartz formula: eGFR (mL/min/1.73m2) = (36.2 × height [cm])/ SCr (μmol /dL). Safety analysis set included all participants who received any amount of study drug.
Baseline (Day -1) up to 54 months
