Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will receive the Study Drug, Vessel Dilator peptide ('VSDL' or Atrial Natriuretic Peptide (ANP)[31-67]).
A lead group of 2 patients will receive a single dose of 250 microgram on day 1 and 500 microgram on Day 2 by subcutaneous bolus. Following review of pharmacokinetic and safety data, a further 6 patients will receive the same doses or up to 2 fold higher if plasma concentrations from the lead group were insufficient to characterise the concentration-time profile.

Outcomes
Primary outcome [1] 269338 0
Pharmacokinetics of vessel dilator peptide following subcutaneous administration in stable patients with chronic heart failure.
Pharmacokinetic parameters Cmax, Tmax, AUC, CL/F, Vz/F and t1/2 will be determined by standard non-compartmental methods. Cmax and Tmax will be taken directly from the observed data.
Timepoint [1] 269338 0
On each of the two dosing days (Day 1 & Day 2):
Blood samples are taken for VSDL assay at -5 minutes pre dose and post dose at 10, 20, 30, 45, 60 min and at hours 2, 3, 4, 6, 8, 10, 12, 18, 24.
Continuous urine collections for measurements of VSDL assay at 0-6, 6-12 and12-24h are collected.
Primary outcome [2] 269339 0
To assess the tolerability and non-invasive haemodynamics of vessel dilator peptide following subcutaneous administration in stable patients with chronic heart failure.
Timepoint [2] 269339 0
On each of the two dosing days (Day 1 & Day 2):
Non invasive BP, HR, respiratory rate, temperature and pulse oximetry will be assessed (using a Philips Intellivue MP5 Bedside Monitor) pre dose and then every 10 mins for first hour post dose, 15 minutely until 4 hours, 30 minutely to 8 hours, then 2 hourly to 14 hours post dose and again at hour 24 and, approximately 1 week post-dosing.
ECGs will be collected pre dose (within 30 minutes of dose administration) and at hour 24 post dose and, approximately 1 week post-dosing.
Transthoracic echocardiography (using a Philips IE33 machine) will be performed to measure estimated EF% (3D and 2D Simpson's), systolic and diastolic strain estimation (speckle tracking, E/E' and tissue doppler) and estimates of PA pressure (PA acceleration time, TR jet peak velocity) at predose (within 1 hour of dose administration) and at hours 2,4 and 6 post dose on each study day.
NT pro-BNP and Troponin will be assessed at baseline, 24 and 48 hours and, approximately 1 week post-dosing.
Biochemistry and a Full Blood Count will be assessed at hour 6 and hour 24 (including CK-MB) post dose on Day 1 and Day 2 and, approximately 1 week post dosing.
Physical examination will be performed one week after dosing.
Monitoring for Adverse Events, for example, hypotension, at all time-points throughout the study.
Secondary outcome [1] 279408 0
To compare the pharmacokinetic results when the plasma samples are assessed by radio immunoassay compared to LC/MS/MS assay.
Timepoint [1] 279408 0
On each of the two dosing days (Day 1 & Day 2):
Blood samples are taken for VSDL assay at -5 minutes pre dose and post dose at 10, 20, 30, 45, 60 min and at hours 2, 3, 4, 6, 8, 10, 12, 18, 24.
Continuous urine collections for measurements of VSDL assay at 0-6, 6-12 and12-24h are collected.
Secondary outcome [2] 279409 0

Timepoint [2] 279409 0
On each of the two dosing days (Day 1 & Day 2):

Continuous urine collections for measurements of urine creatinine, Na+, K+ and renal safety biomarkers (Kidney Injury Molecule -1; Neutrophil Gelatinase Lipocalin) at 0-6, 6-12 and12-24h will be collected. Urine volume will also be recorded to observe for urine volume reduction. Urinalysis and Biomarkers will be assessed at Baseline, 24 hours and, approximately 1 week post dosing.
