Terminal elimination half-life (t½λz)
Day 1 to Day 4

The t½λz of a single oral dose of AZD5462 in participants with renal impairment compared with healthy control participants matched at a group level will be assessed.

Apparent total body clearance (CL/F)
Day 1 to Day 4

The CL/F of a single oral dose of AZD5462 in participants with renal impairment compared with healthy control participants matched at a group level will be assessed.

Non-renal clearance of drug from plasma (CLNR/F)
Day 1 to Day 4

The CLNR/F of a single oral dose of AZD5462 in participants with renal impairment compared with healthy control participants matched at a group level will be assessed.

Apparent volume of distribution based on the terminal phase (Vz/F)
Day 1 to Day 4

The Vz/F of a single oral dose of AZD5462 in participants with renal impairment compared with healthy control participants matched at a group level will be assessed.

Renal clearance of drug (CLR)
Day 1 to Day 2

The CLR of a single oral dose of AZD5462 in participants with renal impairment compared with healthy control participants matched at a group level will be assessed.

Frequently asked questions about AZD5462

What is AZD5462 used for?

AZD5462 is an investigational small molecule being developed for chronic heart failure and renal impairment. AstraZeneca has studied it in a Phase 2b trial in patients with chronic heart failure and a Phase 1 pharmacokinetic study in participants with renal impairment. It is not approved for any indication and remains in clinical development.

Who is developing AZD5462?

AZD5462 is being developed by AstraZeneca PLC, which trades on Nasdaq under the ticker AZN. The company sponsored both the Phase 2b chronic heart failure study and the Phase 1 renal impairment pharmacokinetic study of the compound.

What phase is AZD5462 in?

AZD5462 has completed a Phase 2b trial in chronic heart failure and a Phase 1 pharmacokinetic study in renal impairment. No active trials are currently listed. The drug is investigational and has not been approved by the FDA or any other regulatory agency for any indication.

What clinical trials is AZD5462 in?

AZD5462 has been evaluated in two completed trials. NCT06299826 was a Phase 2b study in 375 patients with chronic heart failure across the United States, Europe, Japan and India. NCT06661733 was a Phase 1 pharmacokinetic, safety and tolerability study in 16 participants with renal impairment in Bulgaria.

Is AZD5462 the same as [14C]AZD5462 Oral Solution?

Yes, [14C]AZD5462 Oral Solution is an alternative name for AZD5462. The carbon-14 labeled oral solution formulation is used in clinical studies of the same investigational compound, so searches for either name refer to the same AstraZeneca drug candidate.
