Description

This is a Phase Ib randomised, double-blind, placebo-controlled, single-dose, single-centre study to evaluate the renal haemodynamic effects of AZD3427 in participants with heart failure and reduced eGFR. This study will evaluate changes in the volumetric fraction of perfused renal cortex after a single dose of AZD3427 or AZD3427 placebo. These changes will be assessed using \[15O\]H2O PET imaging of the kidneys. Additional endpoints include changes in total renal perfusion, plasma/serum biomarkers of renal function, and safety and tolerability. Infusion with 2 to 4 µg/kg/min dopamine/salin...

  • * Participants must have a known clinical diagnosis of HF NYHA I to III for at least 12 months.
  • * Participants must be on stable HF standard of care medication for at least 4 weeks prior to screening, with no significant dose change or new medications added during that period. If the participant is currently taking diuretics, then diuretics must also be stable for at least 4 weeks prior to screening. It is also expected that there will be no change in treatment between screening (Visit 1) and Visit 3 in terms of drugs known to affect renal haemodynamics, including but not limited to: ACE-Is, angiotensin II receptor blockers, angiotensin receptor-neprilysin inhibitors, mineralocorticoid receptor antagonists, cyclooxygenase inhibitors, endothelin receptors antagonists, phosphodiesterase inhibitors, SGLT2is, and diuretics.
  • * Participants must have a left ventricular ejection fraction of ≤ 40% based on echocardiography conducted within the last 6 months.
  • * Participants must have an eGFR of 30 to 90 mL/min/1.73 m2 (inclusive) assessed by the CKD-EPI, 2021 (creatinine only) equation without including race (Inker et al 2021) at screening.
  • BMI AND WEIGHT:
  • - Participants must have a minimum BMI of 18.0 kg/m2 and a minimum body weight of 50 kg at screening.
  • SEX AND CONTRACEPTIVE REQUIREMENTS:
  • * For female participants, the participant must not be pregnant or lactating and must be of non-childbearing potential, confirmed at screening by one of the following:
  • 1. Postmenopausal, defined as amenorrhoea for ≥ 12 months following cessation of all exogenous hormonal treatments, and with FSH levels in the postmenopausal range.
  • 2. Documentation of irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy. Tubal ligation is not considered as irreversible surgical sterilisation.
  • * All male participants should refrain from fathering a child or donating sperm until 3 months after dosing. The female partner has to be either of non-childbearing potential or has to use a highly effective contraception form of birth control until 3 months after dosing. The female partner should be stable on their chosen method of birth control for at least 3 months prior to dosing.
  • * Male participants who have been sterilised are required to use one barrier method of contraception (condom) from the time of study intervention administration until 3 months after the dosing. The participant must have received medical assessment of the surgical success.
  • INFORMED CONSENT:
  • - Capable of and willing to give signed informed consent as described in Appendix A which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
  • Exclusion Criteria:
  • MEDICAL CONDITIONS:
  • * History of any clinically important disease or disorder which, in the opinion of the investigator, may either put the participant at risk because of participation in the study, or influence the results or the participant's ability to participate in the study.
  • * Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks of screening or planned surgical or other procedure before study completion.
  • * Clinically significant, as judged by the investigator, ventricular arrhythmias requiring pharmacological treatment.
  • * Historical or current evidence of a clinically significant disease or disorder including, but not limited to:
  • 1. Myocardial infarction, stroke, transient ischaemic attack, coronary artery bypass grafting, percutaneous coronary intervention, implantable cardioverter defibrillator implantation, within 12 weeks prior to screening.
  • 2. Primary cardiomyopathy other than dilated, including but not limited to sarcoidosis, amyloidosis, restrictive cardiomyopathy, active myocarditis, constrictive pericarditis, hypertrophic (obstructive) cardiomyopathy, complex congenital heart disease.
  • * Decompensated HF or hospitalisation due to any cause \< 4 weeks prior to screening.
  • * Severe heart valve disease.
  • * Diagnosis of polycystic kidney disease or anatomical causes of chronic kidney disease.
  • * One kidney, renal artery stenosis, or glomerulonephritis.
  • * Anticipated dialysis or renal transplantation within 1 year.
  • * Condition where vasodilatory therapy maybe contraindicated for example but not limited to severe aortic stenosis, hypertrophic obstructive cardiomyopathy, restrictive cardiomyopathy.
  • * History of active malignancy within 2 years, with the exception of fully excised or treated basal cell carcinoma or ≤ 2 squamous cell carcinomas of the skin.
  • * Participants who are under investigation for breast or cervical cancer, including participants with a pap smear of ≥ 3. All investigations must be resolved as negative for breast and cervical cancer at least 12 weeks before screening.
  • * Any clinically important abnormalities in clinical chemistry, haematology, or urinalysis results, as judged by the investigator.
  • * Known or suspected history of drug abuse as judged by the Investigator.
  • * History of alcohol abuse or excessive intake of alcohol as judged by the Investigator, within the 6 months prior to screening.
  • * History of hypersensitivity to injection devices or to drugs with a similar chemical structure or class to AZD3427 or any component of the AZD3427 preparation, or to dopamine or any component of the dopamine preparation, or ongoing clinically important allergy/hypersensitivity.
  • * Participants who cannot communicate reliably with the Investigator.
  • * Vulnerable participants, eg, kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
  • * Known history of ADAs to relaxin or relaxin analogues.
  • * Active infections that significantly affect the patient's health status or in the opinion of the Investigator, may put the participant at risk (eg, HIV, Hepatitis, tuberculosis, etc.).
  • * Plasma donation within 1 month prior to screening or any blood donation/blood loss \> 500 mL during the 3 months prior to screening.
  • PRIOR/CONCOMITANT THERAPY:
  • - If on treatment with other drugs with potential to significantly influence on eGFR (eg, SGLT2i, ACE-I), the participant must have been on a stable dose for at least 4 weeks prior to screening.
  • PDE-5 inhibitors such as sildenafil (eg, taken for erectile dysfunction or other as-needed reasons) and NSAIDs such as diclofenac and ibuprofen should not be taken for 2 days before the PET Sessions 2 and 3 (Visit 2 and Visit 3); paracetamol is allowed.
  • PRIOR/CONCURRENT CLINICAL STUDY EXPERIENCE:
