Methods of determining efficacy of treatment in a subject having heart failure
First Claim
1. A method for determining the efficacy of a treatment a subject having heart failure, the method comprising:
- (a) performing an assay to determine a level of galectin-3 in a biological sample from a subject having heart failure;
(b) comparing the level of galectin-3 in the biological sample of (a) to a reference level of galectin-3;
(c) selecting a subject having an elevated level of galectin-3 in the biological sample of (a) as compared to the reference level of galectin-3;
(d) performing an assay to determine a level of soluble ST2 in a biological sample obtained from the selected subject at a first time point before administration of a treatment;
(e) performing an assay to determine a level of soluble ST2 in a biological sample obtained from the selected subject at a second time point after administration of the treatment and after the first time point; and
(f) determining that the treatment was effective in a selected subject having a decrease in the level of soluble ST2 in the biological sample of (e) as compared to the level of soluble ST2 in the biological sample of (d).

Abstract
Provided are methods for evaluating the risk of an adverse clinical outcome in a subject, deciding whether to discharge or continue treating a subject (e.g., treatment on an inpatient basis), or to initiate or terminate treatment, selecting a subject for participation in a clinical study, and selecting a therapeutic treatment for a subject that include determining a level of ST2 in a biological sample from the subject and determining a level of galectin-3 in a biological sample from the subject. Kits are also provided that contain an antibody that specifically binds to ST2, an antibody that specifically binds to galectin-3, and instructions for using the kit to evaluate the risk of an adverse clinical outcome in a subject, to decide whether to discharge or continue treating a subject (e.g., treatment on an inpatient basis) or to initiate or terminate treatment, to select a subject for participation in a clinical study, and/or to select treatment for a subject.
