Brief Summary:
The purpose of the study is to determine the safety and efficacy of TRC150094 in male patients with cardiometabolic risk. Cardiometabolic risk which is the overall risk of cardiovascular disease (CVD) and diabetes resulting from the presence of hypertension, HDL cholesterol, insulin resistance, dysglycemia and visceral obesity.

Condition or disease Intervention/treatment Phase
Metabolic Cardiovascular Syndrome Drug: TRC150094 Other: Placebo Phase 1 Phase 2

Detailed Description:

20 Subjects will be enrolled in Veeda Clinical research,India and another 20 subjects at Amsterdam, the Netherlands. The maximum duration of participation in the study for each subject will be 9.5 weeks including a less than or equal to 4 weeks screening period, 4 weeks of treatment and a 10 days post treatment follow-up evaluation period.

At each study site, 20 subjects will be enrolled. Each subject will attend the study centre in a fasting state, for a screening visit, 2 study visits (one baseline and one end of treatment), 1 intermediate safety visit and 1 post-study follow-up visit (Total 5 visits). The subjects at each site will be randomized to receive TRC150094 or placebo in a ratio of 1:1. 50 mg dose will be administered once daily (morning) under fasting conditions. Dosing will take place daily on Days 1-28. Subjects will arrive at the study centre for screening visit. Physical examination, vital signs, safety biochemistry and laboratory investigations for verification of inclusion/ exclusion criteria will be performed during screening visit. Subjects meeting all the inclusion criteria and none of the exclusion criteria and who have given their informed consent for the study will be asked to come for the study on Day 0 (or day -1 if required). Baseline investigations (including baseline clamp procedure and hepatic MRS) will be done on Day 0 (or day -1). Subjects will receive properly labelled bottle containing either Active treatment or Placebo as per the randomization number of the subject.

Arm Intervention/treatment
Placebo Comparator: Placebo Other: Placebo
Tablets once daily

Active Comparator: TRC150094 Drug: TRC150094
50 mg Tablets once a day

Primary Outcome Measures :
  1. The safety of TRC150094 once daily dosing for 4 weeks in male patients with increased cardiometabolic risk will be determined. [ Time Frame: 1 month ]
    Safety parameters will include haematology, safety biochemistry, vital signs, ECG and AE check.

  2. The efficacy (in increasing insulin sensitivity) of TRC150094 once daily dosing for 4 weeks in male patients with increased cardiometabolic risk will be determined. [ Time Frame: 1 month ]

    Efficacy assessment will include Insulin Sensitivity to be determined by:

    Rate of Glucose Disposal Suppression of Endogenous Glucose Production Suppression of rate of lipolysis

Secondary Outcome Measures :
  1. The effect of TRC150094 on hepatic fat and metabolic parameters will be evaluated. [ Time Frame: 1 month ]

    Early efficacy markers to be explored includes:

    • Hepatic fat by magnetic resonance spectroscopy
    • Lipid parameters
    • Metabolic markers such as adiponectin, IL-6, TNF-alpha, CRP, glucagon, leptin etc.

  2. The ethnic differences for effect of TRC150094 on Insulin sensitivity parameters will be evaluated. [ Time Frame: 1 month ]
    Difference in insulin sensitivity parameters (rate of glucose disposal) between caucasian and Indian populations.
