Multiple Ascending Dose (MAD) Study of IMT-002 in HLA-DQ8-positive Type 1 Diabetes

Completed · Phase 1 · Has a placebo group

Conditions studied: Type1 Diabetes

In brief

This study is designed to characterize the safety, steady-state pharmacokinetics (PK) of IMT-002, and will serve as a dose range identification for the pharmacodynamic effect of blocking self-antigen presentation in adults with type 1 diabetes (T1D) having the human leukocyte antigen (HLA)-DQ8 gene.

• Clinically significant abnormal physical examination, vital signs, or 12-lead ECG at screening as deemed appropriate by the investigator.
• Has a history of or current clinically significant medical illness including, but not limited to, cardiac arrhythmias or other cardiac disease; significant pulmonary disease; neurologic or psychiatric disease; infection; or any other illness that the investigator considers should exclude the subject or that could interfere with the interpretation of the study results.
• Body mass index (BMI) > 32 kg/m2.
• Unstable blood sugar control defined as one or more episodes of severe hypoglycemia (defined as hypoglycemia that required the assistance of another person) within the last 30 days.

• Unable to avoid medications that affect stomach pH, such as proton pump inhibitors or histamine H2 receptor blockers.
• Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the Investigator, may pose additional risks from participation in the study, may interfere with the subject's ability to comply with study requirements, or that may impact the quality or interpretation of the data obtained from the study.
• Has a history of the human immunodeficiency virus (HIV) antibody positive, or tests positive for HIV; has a history of hepatitis B surface antigen (HBsAg) or hepatitis C antibody (anti-HCV) positive, or another clinically active liver disease, or tests positive for HBsAg or anti-HCV at Screening.
