2. Documentation or confirmation of PH1 as determined by genetic analysis prior to randomization.
3. Mean 24-hour urinary oxalate excretion from the first 2 valid 24-hour urine collections is ≥0.7 mmol/24h/1.73m2
4. If taking pyridoxine (vitamin B6) for the treatment of PH1, must have been on stable regimen for at least 90 days before randomization, and willing to remain on this stable regimen for 12 months from first study drug administration.
5. Patient is able to understand and is willing and able to comply with the study requirements and to provide written informed consent. In the case of patients under the age of legal consent, the legal guardian(s) must provide informed consent and the patient should provide assent per local and national requirements.
|
|
E.4 | Principal exclusion criteria |
1. Medical history includes clinical evidence of extrarenal systemic oxalosis, as determined by the Investigator.
2. Has any of the following laboratory parameter assessments at screening: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >2 × upper limit of normal (ULN), total bilirubin >1.5 x ULN (patients with elevated total bilirubin that is secondary to documented Gilbert’s syndrome are eligible if the total bilirubin is <2 x ULN), international normalized ratio (INR) >1.5 (patients on oral anticoagulant [eg, warfarin] with an INR <3.5 will be allowed)
3. Has known or clinical laboratory evidence of human immunodeficiency virus (HIV) infection; or evidence of current or chronic hepatitis C virus (HCV), or hepatitis B virus (HBV) infection (local laboratory values are acceptable)
4. Estimated GFR of <30 mL/min/1.73m2 at screening (calculation will be based on the Modification of Diet in Renal Disease [MDRD] formula for patients ≥18 years of age and the Schwartz Bedside Formula for patients <18 years of age).
5. Received an investigational agent within the last 30 days or 5 half-lives, whichever is longer, prior to the first dose of study drug, or are in follow-up of another clinical study prior to randomization
Medical Conditions
6. History of renal or liver transplant
7. Has other medical conditions or comorbidities, which in the opinion of the Investigator, would interfere with study compliance or data interpretation
8. History of multiple drug allergies or history of allergic reaction to an oligonucleotide or GalNAc.
9. History of intolerance to subcutaneous (SC) injection(s)
10. Is not willing to comply with the contraceptive requirements during the study period.
11. Female patient is pregnant, planning a pregnancy, or breast-feeding.
12. Unwilling or unable to limit alcohol consumption throughout the course of the study. Alcohol intake of >2 units/day is excluded during the study (unit: 1 glass of wine [approximately 125 mL] = 1 measure of spirits [approximately 1 fluid ounce] = ½ pint of beer [approximately 284 mL]
13. History of alcohol abuse, within the last 12 months before screening, in the opinion of the investigator.

E.5 End points |
E.5.1 | Primary end point(s) |
Percent change in 24-hour urinary oxalate excretion from baseline to Month 6 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
24-hour urine and blood samples will be collected for assessment of pharmacodynamic parameters each month. Urinary oxalate concentrations will be analyzed using a validated central assay at baseline and 6 months to assess the primary endpoint. |
|
E.5.2 | Secondary end point(s) |
• Absolute change in 24-hour urinary oxalate corrected for body surface area (BSA) from baseline to Month 6
• Change in 24-hour urinary oxalate:creatinine ratio (value/upper limit of normal [ULN]) from baseline to Month 6
• Proportion of patients with 24-hour urinary oxalate level at or below 1.5 x ULN at Month 6
• Proportion of patients with 24-hour urinary oxalate level at or below ULN at Month 6
• Change in estimated glomerular filtration rate (eGFR) from baseline to Month 6
• Percent change in plasma oxalate from baseline to Month 6
• Absolute change in plasma oxalate from baseline to Month 6
• Change from baseline (percent and absolute) in 24-hour urinary oxalate excretion, percentage of time that 24-hour urinary oxalate is ≤ 1.5 × ULN, 24-hour urinary oxalate:creatinine ratios and eGFR in the extension periods |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
24-hour urine and blood samples will be collected for assessment of pharmacodynamic parameters each month. Urinary and plasma oxalate concentrations will be analyzed using a validated central assay at baseline and 6 months to assess the secondary endpoints. |
