  • The presence and titer of anti-exenatide antibodies [ Time Frame: Visit 3, Visit 6~18, Visit 21 and Visit 29 (once every visit) ]
    Historically, the small subset of exenatide concentrations associated with antibody titers >625 have been excluded from PK analyses due to evidence that these exenatide concentration measurements were unduly affected by negative interference from these antibodies in the exenatide bioanalytical method. Therefore the exenatide concentrations associated with antibody titers >625 may be excluded from the PK analysis.

Brief Title  ICMJE Study of Exenatide Once-Weekly Suspension in Chinese Patients With Type 2 Diabetes Mellitus
Official Title  ICMJE A Phase 1, Open-Label Study to Evaluate Single and Multiple Dose Pharmacokinetics, Safety, and Tolerability of Exenatide Once-Weekly Suspension in Chinese Patients With Type 2 Diabetes Mellitus
Brief Summary The purpose of this study is to evaluate the pharmacokinetics, tolerability, and safety of single and multiple doses of exenatide once-weekly suspension via subcutaneous (SC) injection using a pre-filled, single-dose autoinjector in male and female Chinese with type 2 diabetes.
Detailed Description This is an open-label, single- and multiple-dose, PK study in Chinese subjects with type 2 diabetes mellitus. Up to 30 patients may initially be enrolled to target at least 20 patients completing the study. Up to 10 more patients (ie, 40 in total) may be subsequently recruited to replace patients who discontinue, provided such discontinuations are not due to significant (based on PI and Sponsor judgment) safety or tolerability issues. Eligible patients will receive their first 2.0-mg dose of exenatide once-weekly suspension via subcutaneous (SC) injection using a pre-filled, single-dose autoinjector at Visit 3 (Day 1).Blood samples will be drawn for up to 168 hours after the first dose on Day 1 to assess single-dose PK for exenatide once-weekly suspension. Patients will receive the second dose of the investigational product (IP) at Visit 6 (Day 8). Thereafter, patients will receive weekly (±1 day) doses of IP up to Visit 18 (Week 14). Intensive and extended PK sampling will be conducted after administration of the final dose (Dose 14) to assess multiple-dose PK for exenatide once-weekly suspension. Follow-up observations will be conducted at Visits 22 to 29 (Weeks 15 to 26), with the final follow-up at/after Visit 29 (Week 26 ±2 days). During follow-up period, Blood samples will be collected for PK analyses. Subjects will be monitored closely for adverse events throughout the study.
