Clinical Trial Summary

The primary objective of this study is to evaluate the pharmacokinetics (PK) of a single dose of olpasiran in participants with normal renal function and participants with various degrees of renal impairment.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 33
• Est. completion date: December 19, 2023
• Est. primary completion date: October 24, 2023
• Accepts healthy volunteers: Accepts Healthy Volunteers
• Gender: All
• Age group: 18 Years to 75 Years

Eligibility

Inclusion:

• Male participants or female participants of nonchildbearing potential between 18 and 75 years of age (inclusive) at the time of Screening.
• Body mass index between 18 and 40 kg/m^2 (inclusive) at the time of Screening.
• Eligible participants classified based on established need for renal replacement therapy and eGFR at Screening. Assignment will be based on eGFR at Screening.

1. Group 1 (Normal): eGFR = 90 mL/min and no history of renal disease.

2. Group 2 (Mild): 60 = eGFR = 89 mL/min.

3. Group 3 (Moderate): 30 = eGFR = 59 mL/min.

4. Group 4 (Severe): 15 = eGFR = 29 mL/min without dialysis.

5. Group 5 (Kidney Failure): eGFR < 15 mL/min and dialysis patients (off-dialysis).

6. Group 6 (Kidney Failure): eGFR < 15 mL/min and dialysis patients (on-dialysis).

Exclusion:

• Active liver disease or hepatic dysfunction, defined as aspartate aminotransferase or alanine aminotransferase > 2 times the upper limit of normal.
• Clinically significant hyperkalemia (defined by serum potassium concentration as > 5.5 mEq/L for Groups 1 to 4, > 6 mEq/L for Groups 5 and 6) at Screening or Check-in.
• History of hypersensitivity, intolerance, or allergy to any drug compound, or other substance, unless approved by the Investigator (or designee) and in consultation with the Sponsor.
• Female participants with a positive pregnancy test at Screening or Check-in.
• Participant has received a dose of an investigational drug within the past 30 days or 5 halflives, whichever is longer, prior to Check-in.

Participants in Group 1 only (participants with normal renal function) are excluded if:

• A history of renal disease or renal injury as indicated by medical history or an abnormal renal function profile at Screening or Check-in. Participants in Groups 2 to 6 (participants with varying degrees of renal impairment) are

excluded if:

• A change in disease status within 30 days of Screening, as documented by the participant's medical history, deemed clinically significant by the Investigator.

Related Conditions & MeSH terms

• Renal Impairment
• Renal Insufficiency

Intervention

Drug:
• Olpasiran
Participants will receive olpasiran by subcutaneous (SC) injection.
