Study Overview

Brief Summary

This is a randomized, placebo-controlled, double-blind study to evaluate the efficacy, safety, and pharmacodynamics (PD) of multiple doses of REMD-477 in subjects who have Type 1 diabetes and are currently receiving insulin treatment. This study will determine whether REMD-477 can decrease daily insulin requirements and improve glycemic control after 12 weeks of treatment in subjects diagnosed with Type 1 diabetes with fasting C-peptide < 0.7 ng/mL at Screening.

The study will be conducted at multiple sites in the United States. Approximately 150 subjects with type 1 diabetes on stable doses of insulin will be randomized in a 1:1:1 fashion into one of three treatment groups.

  • •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], known hemoglobinopathies, and renal dysfunction [eGFR < 60 ml/min]);
  • •Any severe symptomatic hypoglycemic event associated with a seizure or requiring help from other people or medical facility in the past 6 months;
  • •Myocardial infarction, unstable angina, revascularization procedure, or cerebrovascular accident ≤12 weeks before screening;
  • •History of New York Heart Association Functional Classification III-IV cardiac disease;
  • •Current or recent (within 1 month of screening) use of diabetes medications other than insulin - subjects on an SGLT2 inhibitor should be discontinue the SGLT2 inhibitor during the Screening Period, at least 2 weeks prior to the start of the Lead-in Period;
  • •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 > 10 cigarettes/day, and/or is unwilling to abstain from smoking during admission periods;
  • •Known sensitivity to mammalian-derived drug preparations, recombinant protein-based drugs or to humanized or human antibodies;
  • •History of illicit 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 (MEN) or family history of MEN;

  • •Known or suspected susceptibility to infectious disease (e.g. taking immunosuppressive agents or has a documented inherited or acquired immunodeficiency);
  • •Known history of 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;
  • •Unable or unwilling to follow the study protocol or who are non-compliant with screening appointments or study visits;
  • •Any other condition(s) that might reduce the chance of obtaining study data, or that might cause safety concerns, or that might compromise the ability to give truly informed consent
  • •Other inclusion and exclusion criteria may apply.
