A Study to Evaluate the Pharmacokinetics, Safety, and Pharmacodynamics of Olpasiran in Participants With Normal Renal Function and Participants With Various Degrees of Renal Impairment

This is an interventional basic science trial for Renal Impairment focused on measuring Olpasiran, Renal Impairment, Normal Renal Function, AMG 890 Read More

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.
