To evaluate the safety and tolerability of single and multiple ascending doses of PB1023 administered as a subcutaneous (SC) injection in adult subjects with T2DM.

Secondary objectives:

  1. To characterize the pharmacokinetic profile of PB1023 after single and multiple ascending doses of PB1023.
  2. To assess the pharmacodynamic response of various single and multiple doses of PB1023 (daily fasting plasma glucose, and serial glucose, c-peptide and insulin levels in response to a liquid Mixed Meal Tolerance Test (MMTT).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety/Tolerability
Time Frame: Screening to Final Visit (up to approximately 10 weeks for SAD and 14 weeks for MAD)
Safety will be evaluated by analyses of incidence of adverse events of interest (possibly related to the class of drug) and other adverse events. Vital signs, ECGs and safety laboratory parameters will also be presented.
Screening to Final Visit (up to approximately 10 weeks for SAD and 14 weeks for MAD)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
