## Abstract

The present invention provides antibodies that bind to the human glucagon receptor, designated GCGR and methods of using same. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to human GCGR. The antibodies of the invention are useful for lowering blood glucose levels and blood ketone levels and are also useful for the treatment of diseases and disorders associated with one or more GCGR biological activities, including the treatment of diabetes, diabetic ketoacidosis, long-term complications associated with diabetes, or other metabolic disorders characterized in part by elevated blood glucose levels, including stress hyperglycemia.

## Claims

### Claim 1

A method of reducing the severity of stress hyperglycemia in a patient, or for treating a patient suffering from stress hyperglycemia wherein the patient exhibits elevated levels of blood glucose caused or exacerbated by one or more stress-inducing stimulus or glucose-elevating stimulus, the method comprising administering to a patient a therapeutically effective amount of a composition comprising a glucagon receptor antagonist, wherein the glucagon receptor antagonist is an isolated human monoclonal antibody, or an antigen binding fragment thereof, specific for the human glucagon receptor, and wherein the isolated human monoclonal antibody or the antigen-binding fragment thereof is capable of blocking the binding of glucagon to the glucagon receptor such that the patient's blood glucose level is lowered.

### Claim 2 (depends on 1)

The method of claim 1, wherein the patient is identified on the basis of having a blood glucose level greater than about 140 mg/dL.

### Claim 3 (depends on 1)

The method of claim 1, wherein the stress-inducing stimulus or glucose elevating stimulus is selected from the group consisting of pre-existing type 1 or type 2 diabetes, hypertonic dehydration, infusion of catecholamine pressors, parenteral nutrition, enteral nutrition, glucocorticoid therapy, obesity, aging, excessive dextrose administration, pancreatitis, sepsis, stroke, traumatic head injury, hypothermia, hypoxemia, uremia, cirrhosis, anesthesia, pre-operative or post-operative hospital stays, peri-operative hyperglycemia, admission to an emergency room, a trauma center, or an intensive care unit, prolonged hospital stays, surgical procedures, an infection and a chronic illness.

### Claim 4 (depends on 1)

The method of claim 1, wherein the isolated human monoclonal antibody or antigen-binding fragment thereof comprises the complementarity determining regions (CDRs) of a heavy chain variable region (HCVR), wherein the HCVR has an amino acid sequence of SEQ ID NO: 86; and the CDRs of a light chain variable region (LCVR), wherein the LCVR has an amino acid sequence of SEQ ID NO: 88.

### Claim 5 (depends on 4)

The method of claim 4, wherein the isolated human monoclonal antibody or antigen-binding fragment thereof comprises a heavy chain variable region (HCVR) having an amino acid sequence of SEQ ID NO: 86.

### Claim 6 (depends on 4)

The method of claim 4, wherein the isolated human monoclonal antibody or antigen-binding fragment thereof comprises a light chain variable region (LCVR) having an amino acid sequence of SEQ ID NO: 88.

### Claim 7 (depends on 4)

The method of claim 4, wherein the isolated human monoclonal antibody or antigen-binding fragment thereof comprises: (a) a HCVR having an amino acid sequence of SEQ ID NO: 86; and (b) a LCVR having an amino acid sequence of SEQ ID NO: 88.

### Claim 8 (depends on 4)

The method of claim 4, wherein the isolated human monoclonal antibody or antigen-binding fragment thereof comprises:

### Claim 16 (depends on 14)

The method of claim 14, wherein the non-diabetic patient is a non-critically ill non-diabetic patient.

### Claim 17 (depends on 14)

The method of claim 14, wherein the non-diabetic patient is administered insulin as a second therapeutic agent.

### Claim 18 (depends on 1)

The method of claim 1, wherein the administering of the antibody results in lowering the blood glucose level to between about 80 mg/dL to about 140 mg/dL.

### Claim 19 (depends on 18)

The method of claim 18, wherein the administering of the antibody results in lowering the blood glucose level to between about 80 mg/dL to about 110 mg/dL.

### Claim 20 (depends on 18)

The method of claim 18, wherein the administering of the antibody results in lowering the blood glucose level to between about 100 mg/dL to about 140 mg/dL.
