GENETIC VARIABILITY TO GLP1 TREATMENT

GENGE400 enrolled

Overview

The goal of this retrospective study is to assess whether a selection of genetic variants may allow us to identify individuals who will have a satisfactory response after GLP-1 treatment in terms of weight loss, sugar level reduction, and adverse events. Participants will The study consists of a single visit at the diabetes unit clinic at the involved study sites. The following will be performed for every subject at the study screening enrollment visit: * Informed consent * Study eligibility (Inclusion / Exclusion criteria) * Collection of demographic data (age (date of birth), gender, ethnic origin) * General and T2DM medical history review (per subject file) * Concomitant medication review (at enrollment) * Physical attributes (Body Weight, Height, BMI) * Allocation to study cohort and study subgroup * Saliva and blood collection for genetic tests * Self-reported questionnaire for Ozempic (Semaglutide) experience

Interventions

DNA extracted from saliva / oral mucosa will be tested for diversities reported in the literature known to be associated with T2DM and Obesity and which may have a potential impact on the response to treatment with Semaglutide. In addition, the DNA will be screened for new diversities that have a potential impact on the response to treatment. working assumption of the study is that there can be 3 types of genetic variants that affect the drug's effectiveness and/or side effects.

differential expression analysis with RNA-sequencing (RNA seq) experimentsGENETIC

Performing small RNA sequencing experiments on an Illumina Next-Generation Sequencing (NGS) machine to investigate microRNAs (miRNAs) or other small non-coding RNAs involves specific steps tailored to the unique characteristics of these molecules

Inclusion Criteria: 1. Diagnosed with type 2 diabetes (for participant in Cohort A) or Obese (for participant in Cohort B) and treated with Ozempic (Semaglutide) S.C. injection for at least 24 weeks. 2. Subject is male/female between 18 to 80 years old (both inclusive) at the time of enrollment. 3. Subject BMI above 30 kg/m2 at treatment initiation. 4. Subject does not belong to any vulnerable population, is willing and able to provide written informed consent prior to any study procedure. 5. Participant understands the nature of the procedure and is willing and able to comply with all requirement of the protocol. Exclusion Criteria: 1. Subject falls under contraindications to Ozempic (Semaglutide) label 2. Subject known or suspected for hypersensitivity to any GLP-1RA or related products, or allergic constitution 3. Subjects suffers from any other condition affecting body weight. 4. Subject with history of chronic or acute pancreatitis 5. Subject have a history of a major cardiovascular and/or cerebrovascular disease within the 6 months before screening. 6. Presence or history of malignant neoplasm within 5 years prior to screening day. 7. Subject suffers from any renal impairment (Cr \> 2 mg/dl). 8.
