Mechanism of Ketogenic Diet-Induced Hypercholesterolemia

Very-low carbohydrate ketogenic diets can dramatically increase blood cholesterol levels, particularly in normal-weight people, for reasons that are not well understood. This study will enroll normal-weight adults, will identify "responders" who develop high cholesterol on a ketogenic diet, and will measure rates of production and removal of certain types of cholesterol-carrying particles called lipoproteins in responders. The results will clarify the mechanism by which a ketogenic diet can cause high cholesterol in certain susceptible people.

Study of SHR-1209 Administered by Single-site or Multiple-site Subcutaneous Injections in Healthy Volunteers

In order to improve the medication convenience and compliance of patients and facilitates in the long-term control of disease condition, it is planned to reduced the number of injections to one per administration. The study aims to compare the safety and pharmacokinetics data to assess feasibility of single-site and multiple-site injection for administration.

Evaluation of the Effects of Two Dietary Supplement Formulations on the Lipid Profile in Mild Hypercholesterolemia

A single-center, randomized, parallel-group, double-blind, placebo-controlled clinical study followed by an open-label phase to evaluate the effects of a new formulation of a supplement on lipid profile in subjects with mild hypercholesterolemia who are non-responsive to the Mediterranean diet. The study population consists of 99 subjects with mild hypercholesterolemia who are non-responsive to the Mediterranean diet. The participants will be divided into three groups: Group A: Test Product A (study product) Group B: Test Product B (comparative product) Placebo group: placebo The following visits are scheduled during the study: T-2 (day -35) - Screening visit, 5 weeks before T0 T-1 (day -28) - Enrollment visit, 4 weeks before T0 T0 (day 0) - Randomization visit, baseline T1 (day 56) - Interim visit, 8 weeks after T0 T2 (day 112) - Final visit, 16 weeks after T0 After the first 8 weeks of the study (double-blind), all three groups will continue with only Product A for an additional 8 weeks. This experimental design aims to highlight whether any differences between Test Product A and Test Product B observed during the first 8 weeks can be minimized when both arms receive the same treatment. Additionally, the effect of Product A will be observed at 8 and 16 weeks, thus providing efficacy data over a longer treatment period. This may also provide insights into the potential achievement of a plateau. Regarding the placebo group, it will be possible to distinguish the effect of the diet alone from the combined effect of the diet and supplementation with Test Product A.
