Arms Assigned Interventions
Placebo Comparator: Placebo
Each Strata of the study will have a placebo control. In strata A, the chance of getting active drug is 4 out of 5, in Strata B the chance of getting active drug is 3 ot of 4, and in Strata C, the chance of getting active Drug is 4 out of 5. In the event that a patient is allocated to receive placebo, the treatment may be stopped if the patient's condition fails to improve or worsens during the placebo infusion.
Drug: Placebo
An infusion of an identically appearing solution of sugar water will be intravenously administered.
Experimental: Strata 1 CXL-1020
Patients assigned to CXL-1020 in strata one will have their dose increased from the initial dose 2 times during the study period. The treatment may be stopped if the patient's condition fails to improve or worsens during the infusion.
Drug: Strata 1 CXL-1020
Intravenous infusion of CXL-1020, up-titrated, so that 3 different dosages are administered over 6 hours
Experimental: Strata 2 CXL-1020
In strata 2, patients who are assigned to active treatment will receive one of up to 3 possible fixed dose levels of CXL-1020 for a period of 6 hours. The treatment may be stopped if the patient's condition fails to improve or worsens during the infusion.
Drug: Strata 2 CXL-1020
One of 3 different dosages of CXL-1020 administered at a fixed dosage level for 6 hours.
Experimental: Strata 3 CXL-1020
In strata 3, patients assigned to receive CXL-1020 will receive a fixed dose of CXL-1020 for 6 hours, and then the dose may be increased or decreased, based on the investigators assessment of the patient. The treatment may be stopped if the patient's condition fails to improve or worsens during the infusion.
Drug: Strata 3 CXL-1020
A fixed dose level of CXL-1020 will be administered for the initial 6 hours of treatment in Strata 3 and then dosage will be altered up or downward based on the investigators observation of the patient's condition.

Detailed Description:

Each of the 3 strata are described below:

Invasive Strata 1: This is a randomized, double-blinded stratum that will enroll up to 65 patients who are hospitalized with symptomatic heart failure who have indwelling PA catheters allowing invasive hemodynamic evaluation. Each patient will receive a six hour intravenous infusion of either placebo or CXL-1020.

Non-Invasive Strata 2: This is a randomized, double-blinded stratum which will enroll up to approximately 72 patients (in several cohorts with 12-24 patients each) who neither require, nor have in place, an indwelling PA catheter for hemodynamic monitoring, but meet study entrance criteria for symptoms of heart failure, (dyspnea at rest)and systolic dysfunction by specific echocardiography criteria. Monitoring of drug effects will be performed by Echocardiography.

Invasive-Strata 3: This is a randomized, double-blinded stratum that will begin after an evaluation of a substantial number of patients in Strata A and B and will enroll approximately 15-30 patients using the same general enrollment criteria as in Invasive Strata A.
