A Study Understanding How Much CDR132L Enters the Bloodstream After Injection Under the Skin Compared to Injection Into a Vein in Healthy Participants

Official title

A Bioavailability Study Comparing the Pharmacokinetics of CDR132L Following Subcutaneous and Intravenous Administration in Healthy Participants

Overview

This study is being done to understand how much of the medicine (CDR132L) enters the bloodstream after injection under the skin compared to injection into a vein in healthy people. This will help us find the best way to give the medicine to people living with heart failure. The study will assess what the body does to the medicine, and how safe it is.

Interventions

• Drug CDR132L (i.v.)
  CDR132L will be administered intravenously.
• Drug CDR132L (s.c.)
  CDR132L will be administered subcutaneously.

Primary outcome measures

• Area under the CDR132L plasma concentration-time curve (AUC 0-tz) from 0 hours to tz after a single dose, where tz is the time of last quantifiable concentration [Time frame: From 0 to 840 hours after CDR132L administration]

Secondary outcome measures (10)

• Area under the CDR132L plasma concentration-time curve from 0 hours and extrapolated to infinity after a single dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Maximum observed CDR132L plasma concentration after a single dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Time to maximum observed CDR132L plasma concentration after a single dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Terminal half-life for CDR132L after a single dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Area under the CDR132L plasma concentration-time curve from 0 hours to tz after a single dose, where tz is the time of last quantifiable concentration, divided by dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Maximum observed CDR132L plasma concentration after a single dose divided by dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Total plasma clearance of CDR132L after a single dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Apparent volume of distribution of CDR132L after a single dose based on plasma concentration values [Time frame: From 0 to 840 hours after CDR132L administration]
• Mean residence time for CDR132L after a single dose [Time frame: From 0 to 840 hours after CDR132L administration]
• Number of adverse events [Time frame: From first CDR132L administration (day 1) to day 141]

Eligibility criteria

Inclusion criteria

• Supine blood pressure at screening (visit 1) outside the range of 90-139 millimeters of mercury (mmHg) for systolic or 50-89 mmHg for diastolic.

• Known history of severe symptomatic untreated anaemia in the 90 days prior to screening (visit 1) (e.g., haemoglobin <90 grams per litre (g/L))
• Presence or history (as declared by the participant or reported in the medical records) of acute or chronic kidney disease or injury.
• Presence of thrombocytopenia, defined as thrombocyte count <150 x 10\^9 cells/L at screening (visit 1), or history (as declared by the participant or reported in the medical records) of bleeding disorder.
• Presence or history (as declared by the participant or reported in the medical records) of conditions associated with disruption of blood-brain barrier (e.g. multiple sclerosis).
