Clinical Trial Summary

PBL 1427 is a Dipeptidyl peptidase (DPP)-IV inhibitor being developed for treatment of type 2 diabetes. Although a number of DPP-IV inhibitors have been described, there still exists a need for new DPP-IV inhibitors that have better half-life, advantageous potency, stability and selectivity, less toxicity and/or better pharmacodynamic properties.

Description:

As per the randomization schedule, capsule(s) of A or B will be administered to each subject with 240 mL of water at ambient temperature. Subjects will be instructed not to chew or crush the capsule(s) but to consume it as a whole. Compliance for dosing will be assessed by a thorough check of the oral cavity immediately after dosing. Administration of investigational products will be carried out while the subjects are in sitting posture and they will be instructed to remain seated for two hours after dosing except when clinically indicated to change the posture or in case of any natural exigency. Thereafter, the subjects will be allowed to engage in normal activities while avoiding severe physical exertion.

The following treatments in the below cohorts will be followed as given below:

Cohort 1: A single oral dose of 20 mg of PBL 1427 (n=6) or placebo (n=2) Cohort 2: A single oral dose of 40 mg (20 mg X 2 capsules) of PBL 1427 (n=6) or placebo (n=2) Cohort 3: A single oral dose of 80 mg (20 mg X 4 capsules) of PBL 1427 (n=6) or placebo (n=2) Cohort 4: A single oral dose of 150 mg of PBL 1427 (n=6) or placebo (n=2) Cohort 5: A single oral dose of 300 mg (150 mg X 2 capsules) of PBL 1427 (n=6) or placebo (n=2) Cohort 6: A single oral dose of 600 mg (150 mg X 4 capsules) of PBL 1427 (n=6) or placebo (n=2)

Dose levels may be modified and intermediate dose levels might be tested to determine the maximum tolerated dose (MTD)

The number of cohorts, dose levels, frequency and conditions of administration for the subsequent cohort may be altered by the Principal investigator and Sponsor after evaluation of the results of the previous group.

• Regular smokers who smoke more than 10 cigarettes daily or have difficulty abstaining from smoking for the duration of each study period.

• History of drug dependence or alcoholics

Outcome

Type	Measure	Description	Time frame	Safety issue
