Study of JK07 in Subjects With Heart Failure With Reduced Ejection Fraction (HFrEF)
This is a Phase 1, randomized, double-blind, placebo-controlled, single-ascending dose study to assess the safety, tolerability, immunogenicity, PK, and exploratory efficacy of JK07 in subjects 18 to 80 years of age with HFrEF ≤40%.
Initially 5 cohorts are planned with the option to expand the study to a total of 7 cohorts. The size of the cohorts will range from 5 to 9 subjects. Each cohort will include one single active unblinded sentinel subject receiving a single IV dose of JK07 prior to randomized single dose administration of JK07 or placebo [3:1] in the remainder of the cohort.
Stanford is currently accepting patients for this trial.

determined discretion (except for diuretics) for at least 2 months prior to informed

discretion of the investigator, but only if both the following criteria are met: (a)

procedure during the study period.
8. Sustained systolic blood pressure <90 mm Hg and/or diastolic blood pressure <50 mm Hg.

sustained atrial fibrillation when a heart rate of up to 110 beats per minute is
10. Cerebrovascular accident or hospitalizations for CV (cardiovascular) causes other than
routine percutaneous procedures such as device, battery, generator changes or
pacemaker lead insertion/ replacement or device generator changes, including HF, chest
pain, stroke, transient ischemic attack, or arrhythmias within 3 months prior to

in the opinion of the Investigator, would affect efficacy or safety evaluation or
place the subject at risk.
12. History or evidence of clinically significant arrhythmia uncontrolled by drug therapy
or use of an implantable defibrillator, long QT syndrome, or evidence of QT
prolongation with QTcF >450 ms for males or QTcF >470 ms for females prior to
13. Clinically significant renal dysfunction as measured by the estimated GFR <45
mL/min/1.73m2 at screening, or a clinically significant change in renal function
between screening and baseline.

phosphatase > 2.0 × ULN, AST >2.0 × the ULN, or GGT >2.0 × the ULN or serum bilirubin
≥ 1.2 × the ULN at screening, or a clinically significant change in liver function
between screening and baseline.
15. Subjects with alteration of the coagulation panel (INR) and/or PT ≥ 1.5 × the ULN;
aPTT ≥ 1.5 × ULN, or serum albumin ≤ 3 gm/dL. For subjects on warfarin or other
anticoagulants, an INR (or PT) considered by the Principal Investigator as
therapeutically appropriate will be allowed.
