Clinical Trial Summary

This is a randomized, placebo-controlled, double-blind study to evaluate safety, tolerability and pharmacodynamics of REMD-477 in subjects who have Type 1 diabetes and are currently receiving insulin treatment. This proof of concept study will determine whether glucagon receptor blockade using a single dose REMD-477 can improve short-term glucose homeostasis in people with Type 1 diabetes.

Description:

The study will be conducted at two sites in the United States, and approximately 20 subjects with type 1 diabetes will be enrolled. Eligible subjects will be admitted to the clinical research unit, to carefully monitor blood glucose; and establish the baseline insulin requirement for maintaining targeted normoglycemia (postabsorptive: 90-120 mg/dL; and postprandial: <180 mg/dL).

The patients will then be subjected to a hyperglycemic period (250-300 mg/dL) by a stepwise reduction in insulin infusion. After receiving a single SC dose of REMD-477 or matching placebo in a double-blinded fashion, all subjects will be assessed for the post-treatment 24-hour insulin requirement needed to maintain targeted normoglycemia (postabsorptive: 90-120 mg/dL; and postprandial: <180 mg/dL); and to be monitored closely for safety, tolerability and targeted glycemic control, for a 48-hr period. After the in-patient residency period, subjects will return to the clinic for weekly out-patient safety follow-up visits for 8 weeks.

• ALT and/or AST within <1.5x ULN at screening;

• Serum amylase and lipase within normal limits at screening;

• Able to provide written informed consent approved by an Institutional Review Board (IRB).

Exclusion Criteria:

• History or evidence of clinically-significant disorder or condition that, in the opinion of the Investigator, would pose a risk to subject safety or interfere with the study evaluation, procedures, or completion;

• Significant organ system dysfunction (e.g., clinically significant pulmonary or cardiovascular disease, anemia [Hemoglobin <10.0 g/dL], and renal dysfunction [eGFR <90 ml/1.73M2/min]);

• Any severe symptomatic hypoglycemic event associated with a seizure or requiring help from other people or medical facility in the past 6 months;

• Use of steroids and/or other prescribed or over-the-counter medications that are known to affect the outcome measures in this study or known to influence glucose metabolism;

• Smokes tobacco;

• Known sensitivity to mammalian-derived drug preparations, recombinant protein-based drugs or to humanized or human antibodies;

• History of illegal drug use or alcohol abuse within the last 6 months or a positive drug urine test result at screening;

• History of pancreatitis, pancreatic neuroendocrine tumors or multiple endocrine neoplasia;

• History of pheochromocytoma, or family history of familial pheochromocytoma;

• Known or suspected susceptibility to infectious disease (eg, taking immunosuppressive agents or has a documented inherited or acquired immunodeficiency);

• Positive for human immunodeficiency virus (HIV) antibodies, hepatitis B surface antigen (HbsAg), or hepatitis C antibodies (HepC Ab);

• Participation in an investigational drug or device trial within 30 days of screening or within 5 times the half-life of the investigational agent in the other clinical study, if known, whichever period is longer;

• Blood donor or blood loss >500 mL within 30 days of Day 1;

• Women who are pregnant or lactating/breastfeeding;

• Regular exercise >120 min/week within 14 days of Day 1;

• Unable or unwilling to follow the study protocol or who are non-compliant with screening appointments or study visits;

• Family history of multiple endocrine neoplasia.
