Areas of Expertise
Cholesterol-lowering studies

At INQUIS Clinical Research, we have extensive experience in designing and executing cholesterol-lowering studies. We can perform a power analysis to determine the sample size needed to detect an effect of your product and design and execute a trial to address your research objectives. With access to pools of participants with slightly elevated cholesterol levels, we can recruit the appropriate population for your clinical trial and research objectives. Cholesterol-lowering studies performed at INQUIS Clinical Research can also be used to support novel fiber claims. As part of our cholesterol-lowering studies, we can measure:

  • LDL cholesterol
  • Oxidized LDL cholesterol
  • HDL cholesterol
  • Apolipoprotein A1 (apoA1)
  • Apolipoprotein B (apoB)
  •  Measures of inflammation

Insulin sensitivity/glucose tolerance

INQUIS Clinical Research has extensive experience in conducting research trials that examine attenuation of glucose responses. With both short-term measures of glucose response and long-term measures of glucose tolerance, we can conduct the trial that is best suited to your goals.

Measuring postprandial insulin levels is an important component of clinical trials, to ensure that insulin levels are not disproportionately increased in relation to glucose response. With acute studies measuring postprandial insulin response as well as long-term studies of insulin sensitivity, we are able to address your research needs.

Chronic inflammation

Markers of chronic inflammation are important indicators of long term health risks. At INQUIS Clinical Research, we design and execute trials that examine cardiovascular disease risk factor profiles, as well as measure other markers of inflammation, including antioxidants, CRP, and interleukin 6 and 3. With an extensive participant database, including volunteers with mild illnesses, we can recruit the appropriate study population for your research objectives.

Changes in body composition

Tracking changes in body composition over time with a specific treatment helps to better understand the mechanism of action as well as potential long-term effects. At INQUIS Clinical Research, our research includes DEXA (dual energy x-ray absorptiometry) scans to determine changes in fat composition over time, as well as BIA (bioelectrical impedance analysis) to monitor changes body fat percentages over time.
