Description of intervention(s) / exposure
Chemical Name (CAS): 3-[4-(2,6-dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]oct-1-yl]propionic acid
Laboratory Codes: BIO-9002
CAS number: 340021-17-2
Other names: BG9928, Adentri
The BG9928 drug product for intravenous (IV) use is supplied as a sterile, lyophilized powder in vials containing 20 mg of BG9928. The active drug product contains the following inactive ingredients: mannitol, histidine, sodium chloride, and sodium hydroxide. BG9928 is reconstituted with sterile water for injection and will be administered intravenously, in an appropriate volume as defined in the Directions for Handling and Administration (DHA), via syringe or infusion pump over 30 minutes, to subjects randomized to receive active treatment.
Study treatment should be initiated within 24 hours of the first dose of IV diuretic for the treatment of the current episode of Acute Decompensated Heart Failure (ADHF), and will be administered daily every 12 hours (q12h) for up to 5 days. Each subject will receive placebo or BG9928 at 0.03 mg/kg, 0.15 mg/kg, or 0.3 mg/kg every 12 hours (q12h) at randomization evenly (1:1:1:1) resulting in 225 patients per treatment group.

24 hours
Secondary outcome [1] 7482 0
Effect of BG9928 when added to standard therapy in subjects with ADHF and renal insufficiency on:

Worsening renal function during the double-blind treatment period up to Day 5 (or discharge if prior to Day 5). Incidence of worsening renal function defined as an increase in serum creatinine (based on data from the central laboratory) at any time by at least 0.3 mg/dL from baseline up to Day 5 or discharge if prior to Day 5. Measured at Baseline and daily from day 2 to day 5.

Effect of BG9928 when added to standard therapy in subjects with ADHF and renal insufficiency on: Improvement in Subject Global Clinical Assessments at 24 hours following the first dose. In order to understand the degree to which BG9928 can contribute to improvements in
overall clinical status, a baseline assessment of each subject's overall clinical status will be obtained at different time points and compared with the baseline status. Factors to be
considered by the subject when assessing global status include the following: fatigue, overall discomfort, breathing status, edema, ability to ambulate, etc. Measurements will be made via questionnaire.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization will take place across all study sites using a centralized Interactive Voice/Web Response System (IVRS/IWRS).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The protocol operates a telephone and Web based system for IVRS.The randomization will be stratified by region. Subjects will be randomized to dose groups in a 1:1:1:1 ratio. Subjects withdrawn from the study will not be replaced. At randomization, the IVRS/IWRS will assign a unique 6-digit subject identification number to each subject (the first segment of the number represents the study site and the second segment of the number represents the subject at that study site). The subject’s identification number will be used on all of that subject’s Case Report Forms (CRFs). More details will be provided in the Study Reference Manual. The random sequence is computer generated. Randomization was stratified by geographic region and within each region permuted block randomisation is used to assign treatment groups.

Summary
Brief summary
The Trident-1 study is an International multi-center, randomized, double-blind, placebo controlled phase 3 clinical trial with plans to randomise a total of 900 patients. The purpose of the study is to determine the effects and safety on the body weight of 3 different doses of BG9928 (0.03 mg/kg, 0.15 mg/kg, or 0.3 mg/kg) and placebo given up to a maximum 5 days to subjects hospitalized due to Acute Decompensated Heart Failure (ADHF) and Renal Insufficiency. BG9928 is a A1 receptor antagonist, which from previous studies have demonstrated ability to preserve renal function and promote urine production. The effect of BG9928 on body weight is thus related to the urine output. The study drug will be given in addition to the medication that would normally be given to ADHF patients. This means that patients on placebo still receive normal standard care.
The primary objective of the study is to determine the effect of BG9928, when added to standard therapy, on the change in body weight at 24 hours following the first dose in these subjects. The secondary efficacy objectives of this study are to determine the effect of BG9928, when added to standard therapy, on worsening renal function during the treatment period, the number of days of hospital-free survival (DHFS), the improvement in Dyspnea Symptom and Edema Score, Subject Global Clinical Assessments and Physician Global Clinical Assessment. Additionally the secondary efficacy objectives are measuring the use of concomitant medications to treat heart failure, length of hospital stay, cardiovascular and all-cause mortality and re-hospitalization up to 180 days after the initial dose. The safety objective of the study is to assess the safety and tolerability of BG9928.
Upon screening patients will be randomized evenly into either of the 4 treatment arms and will receive IV study drug infusions twice daily for a maximum treatment period of 5 days 910 doses). Prior to and during hospitalisation period, for a maximum of 7 days, the patients will be monitored via physical exam, vital signs, body weight, ECG diagram, questionnaires, blood samples (including pregnancy test for women of childbearing potential, haematology, chemistry, special kidney tests (BNP, Cystatin C), bone markers ,genetic and PK testing. Safety monitoring and concomitant medication monitoring will be conducted from screening and up to day 30 . Telephone follow-up done at 2, 3 and 6 months after the first study dose.
