Study Details

Study Description

Brief Summary

The primary purpose of this mechanistic study is to evaluate the vasodilatory effects of AZD3427 in adult patients with heart failure and will be performed at approximately 2 study sites in the United Kingdom.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

The study will enroll patients in 2 cohorts in parallel: 1 cohort of patients with heart failure with preserved ejection fraction (HFpEF) and 1 cohort of patients with heart failure with reduced ejection fraction (HFrEF). Each cohort plans to enroll at least 7 evaluable patients.

All patients will receive the same sequence of 5 intra-arterial (IA) infusions into the brachial artery, consisting of a baseline saline infusion of approximately 20 minutes, followed by 3 sequential infusions of AZD3427 at ascending doses of approximately 10 minutes (each) and a washout saline infusion of approximately 15 minutes.

For each patient, the study will last at least 51 days and up to 99 days, including:
  • A screening period of 1 to 42 days (which will include baseline echocardiography)

  • A single-day treatment period during which patients will stay at study site until at least 4 hours after the end of infusions

  • A follow-up period of 49 to 56 days after the end of the last infusion including:

A follow-up phone call on Day 2 (within 24 ± 6 hours post-infusion) A follow-up visit on Day 8 (+ 3 days) A follow-up visit on Day 29 (± 2 days) A follow-up visit on Day 50 (+ 7 days)

Arms and Interventions

Arm Intervention/Treatment
Experimental: Patients with HFpEF or HFrEF

Patients will be enrolled in 2 cohorts in parallel: 1 cohort of patients with HFpEF and 1 cohort of patients with HFrEF. Patients will receive a sequence of 5 IA infusions into the brachial artery, consisting of a baseline saline infusion of approximately 20 minutes, followed by 3 sequential infusions of AZD3427 at ascending doses of approximately 10 minutes (each) and a washout saline infusion of approximately 15 minutes.

Drug: AZD3427
Patients will receive 5 IA infusions of AZD3427 into the brachial artery. The IA infusions of AZD3427 will be administered via a syringe pump, using a polypropylene syringe containing 0.9% (w/v) saline and delivered through an administration set comprising a syringe, extension tubing (PVC), and a 0.2- or 0.22-μm PVDF syringe filter.

Outcome Measures

Primary Outcome Measures

  1. Maximum change from baseline in absolute forearm blood flow in the infused arm during AZD3427 IA infusions [Day 1]

    To determine whether AZD3427 produces a vasodilatory response in the forearm resistance vessels of HFpEF and HFrEF patients, as assessed by forearm blood flow parameters measured using venous occlusion plethysmography.

Secondary Outcome Measures

  1. Number of patients with anti-drug antibody (ADAs) in serum samples at baseline and at Day 8, Day 29, and Day 50 [Day 1, Day 8, Day 29 and Day 50]

    To assess the immunogenicity of AZD3427.

  2. Change from baseline in forearm blood flow ratio in the infused arm (AZD3427 infusion:baseline) after each AZD3427 IA infusion [Day 1]

    To determine whether AZD3427 produces a vasodilatory response in the forearm resistance vessels of HFpEF and HFrEF patients, as assessed by forearm blood flow parameters measured using venous occlusion plethysmography.

  3. Change from baseline in forearm blood flow ratio between arms (infused arm:non-infused arm) after each AZD3427 IA infusion [Day 1]

    To determine whether AZD3427 produces a vasodilatory response in the forearm resistance vessels of HFpEF and HFrEF patients, as assessed by forearm blood flow parameters measured using venous occlusion plethysmography.

Other Outcome Measures

  1. Number of patients with adverse events [From Screening (Day -42 to Day -1) until the Follow-up visit (Day 1, Day 2, Day 8, Day 29, and Day 50)]

    Assessment of safety and tolerability of AZD3427 in HFpEF and HFrEF patients, following low-dose local IA infusion of 3 sequential ascending doses of AZD3427.
