E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective will be to compare the proportion of participants with severe and complicated obesity (defined as BMI ≥35 kg/m2 with at least one major obesity-related comorbidity) achieving weight loss ≥15% at 1 year (52 weeks) with a targeted prescribing pathway (i.e. use of LIRA 3mg according to a pre-specified protocol in combination with standard care provided in Tier 3 services) versus standard care provided in Tier 3 services alone. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to compare the targeted prescribing pathway and standard care in terms of: 1. improving obesity-related co-morbidities (obstructive sleep apnoea, prediabetes, diabetes, hypertension, dyslipidaemia, depression) 2. referral rates to other obesity interventions 3. long-term maintenance (defined as the proportion of participants maintaining weight loss of ≥15% at 104 weeks among those who achieved ≥15% weight loss at 52 weeks) 4. budget impact on a Tier 3 weight management service 5. long-term cost-effectiveness 6. direct healthcare costs in terms of admissions, frequency, and cost of appointments 7. safety-related outcomes 8. adherence 9. patient satisfaction. |

E.4 | Principal exclusion criteria |
Patients who have met any of the following criteria will be excluded from the study: • Diagnosis of Type 1 diabetes • T2DM with treatment on DPP-IV or insulin currently • Treatment with GLP-1 receptor agonists in the past or currently • Treatment with anti-obesity drugs within 12 weeks prior to randomisation • eGFR ≤30ml/min/1.73m2 on serum testing over the last 26 weeks • Females referred to the clinic because of fertility problem • Females of child bearing potential who are pregnant, breast-feeding or intend to become pregnant or are not using or willing to use adequate contraceptive methods (as described in Section 8.3.1 • Have terminal illness • Are not primarily responsible for their own care • Any other significant disease or disorder which in the opinion of the investigator, may either put the participants at risk or may influence the result of the study or the participant’s ability to participate • Untreated or uncontrolled hypothyroidism/hyperthyroidism defined as thyroid-stimulating hormone >6 mIU/litre or <0.4 mIU/litre • Family or personal history of multiple endocrine neoplasia type 2 (MEN2) or familial medullary thyroid carcinoma (FMTC) • Personal history of non-familial medullary thyroid carcinoma • History of chronic pancreatitis or idiopathic acute pancreatitis • Amylase or lipase levels three times higher than the upper normal range • Obesity induced by other endocrinologic disorders (e.g. Cushing’s Syndrome) • Current or history of treatment with medications that may cause significant weight gain, within 12 weeks prior to randomisation, including systemic corticosteroids (except for a short course of treatment, i.e. 7−10 days), atypical antipsychotic and mood stabilizers (e.g. clozapine, olanzapine, valproic acid and its derivatives, and lithium) • Initiation of antidepressants during the last 12 weeks • Previous surgical treatment for obesity (excluding liposuction if performed >1 year before trial entry) • History of other severe psychiatric disorders • History of known or suspected abuse of alcohol and/or narcotics • History of major depressive episode during the last 2 years • Simultaneous participation in other clinical trials of investigational drugs, lifestyle or physical activity interventions. Patients will only be able to take part following participation in a previous clinical trial after a wash-out period of 16 weeks.
