Funded PhD Opportunity Off Target Benefits of GLP-1 therapy in type 2 Diabetes

This opportunity is now closed.

Subject: Biomedical Sciences

Summary

Diabetes is characterized by hyperglycaemia with Type 2 diabetes (T2D) accounting for 90% of all cases (~450M cases globally). Obesity and a lack of exercise increase a person’s risk of T2D. Hyperglycaemia in T2D creates several complications for patients, including risk of heart disease, depression and memory loss. This study will focus on a class of drugs called GLP-1 analogues that are currently used to bring hyperglycaemia under control in T2D. However, early evidence shows that GLP-1 analogues reduce the risk of heart disease and improve depression and memory. A clinical trial assessing the efficacy of liraglutide (a GLP-1 analogue) in early Alzheimer’s disease (AD) is ongoing; however, patients with T2D are excluded.

AIM: To evaluate anti-depressant, anxiolytic, cognitive and cardiovascular outcomes in patients with T2D treated with GLP-1 analogues, as part of their routine clinical care, compared to those treated with other T2D drugs.

EXPERIMENTAL PLAN: Participants receiving GLP-1 therapy as part of their routine clinical care who have a diagnosis of T2D alone and those with both T2D and (AD)/Mild Cognitive Impairment (MCI) will be compared with control groups treated with other T2D drugs, and apparently healthy controls. All participants will be recruited from the WHSTC. Ethical approval and research governance is in place for this study and the recruitment process has been established in on-going studies. This approach will provide an indication of the efficacy of GLP-1 therapy on cognitive outcomes in patients with T2D and MCI/AD.

In brief, the proposed programme of work will address the following objectives:

Objective 1: Compare Beck Depression inventory scores between those on GLP-1 analogues, other T2D drugs, and apparently healthy controls.

Objective 2: Compare Beck anxiety inventory scores in patients on GLP-1 analogues, other T2D drugs, and healthy controls.

Objective 3: Compare Standardised Mini Mental State Exam (SMMSE) scores and Quick Mild Cognitive Impairment screen (qMCI) scores in patients on GLP-1 analogues, other T2D drugs, and apparently healthy controls.

Objective 4: Compare cardiovascular comorbidity in patients on GLP-1 analogues, other T2D drugs, and apparently healthy controls.

Objective 5: Compare Beck depression and anxiety inventories, SMMSE and qMCI in prospective participants at baseline, and 6 months after initiation of therapy to assess changes in scores attributable to GLP-1 analogue therapy. This research will determine whether the cardioprotective benefits of GLP-1 analogue therapy, suggested in clinical trial populations, are realized in the general T2D population. It will also assess if anti-depressant, anti-anxiety and neuroprotective effects of GLP-1 result in significantly improved scores in standardized assessments in a general T2D population. GLP-1 analogues are expensive compared to other T2D drugs and are not normally prescribed to people with newly diagnosed T2D, but as a fourth-line therapy. If the findings of this study indicate GLP-1 analogues reduce heart disease, depression and memory loss in the general T2D population this may promote their use earlier in T2D progression. Prevention of complications would offset the cost of these drugs. This study will provide important information that will inform clinical decision making in T2D treatment.
