Primary Outcome Measures

Name	Time	Method
Change from baseline to the end of the study period in overall severity of neuropathic pain	Baseline to week 12	Change from baseline to the end of the study period in overall severity of neuropathic pain, as assessed by the Brief Pain Inventory Short Form for Diabetic Peripheral Neuropathy (BPI-DPN).; This is a self-reported scale, higher scores indicate greater pain and interference.

Secondary Outcome Measures

Name	Time	Method
Change from baseline to the end of the study period in Neuropathic Pain Symptom Inventory	Baseline to week 12	Change from baseline to the end of the study period in Neuropathic Pain Symptom Inventory (NPSI). This is a self-administered questionnaire used to evaluate neuropathic pain intensity across 5 categories, namely "superficial spontaneous pain", "deep spontaneous pain", "paroxysmal pain", "evoked pain", and "dysesthesia / paraesthesia". There are 10 pain descriptors and 2 items related to abnormal sensations. The scale ranges from 0 (no pain at all) to 10 (worst pain imaginable). The total scores of all items are combined to find the total pain intensity
Change from baseline to the end of the study period in Safety via Adverse Event reporting	Baseline to week 12	Change from baseline to the end of the study period in safety via Adverse Event reporting and incident rate ratio between placebo and Levagen+
Change from baseline to the end of the study period in Safety Markers (FBC)	Baseline to week 12	Change from baseline to the end of the study period in safety Markers (FBC - Full Blood Count) via blood test.
Change from baseline to the end of the study period in Safety Markers (E/LFT)	Baseline to week 12	Change from baseline to the end of the study period in safety Markers (E/LFT) via blood test.
Change from baseline to the end of the study period in Safety (Vitals - BP)	Baseline to week 12	Change from baseline to the end of the study period in Safety Markers vital signs (blood pressure)
Change from baseline to the end of the study period in Safety (Vitals - heart rate)	Baseline to week 12	Change from baseline to the end of the study period in Safety Markers vital signs (heart rate)
Change from baseline to the end of the study period in Medical Outcomes Study - Sleep Scale (MOS-Sleep)	Baseline to week 12	Change from baseline to the end of the study period in Medical Outcomes Study - Sleep Scale (MOS-Sleep). This is a self-administered 12-item questionnaire that includes a Sleep Problem Index and evaluates 6 dimensions of sleep difficulty, namely: "sleep disturbance", "sleep adequacy", somnolence", "quantity of sleep/optimal sleep", "awakening short of breath or with headache", and "occurrence of snoring". The Sleep Problem Index summarises information across 9 items and is rated on a scale of 1 (all of the time) to 6 (none of the time).
Change from baseline to the end of the study period in Depression Anxiety and Stress Scale (DASS-21)	Baseline to week 12	Change from baseline to the end of the study period in Depression Anxiety and Stress Scale (DASS-21). The DASS-21 is a self-reported questionnaire derived from the original 42-item DASS and is a quantitative measure of distress. It consists of 3 subscales: the depression subscale (DASS-D), anxiety subscale (DASS-A) and stress subscale (DASS-S). Each subscale contains 7 items which are rated on a 4-point severity/frequency scale. The scores for each subscale are calculated by summing the scores for the relevant items. Higher scores indicate greater distress.
Change from baseline to the end of the study period in Glycaemic control (HbA1c)	Baseline to week 12	Change from baseline to the end of the study period in Glycaemic control (HbA1c)
Change from baseline to the end of the study period in Glycaemic control (fasting blood glucose)	Baseline to week 12	Change from baseline to the end of the study period in Glycaemic control (fasting blood glucose)
Change from baseline to the end of the study period in Anthropometry (weight)	Baseline to week 12	Change from baseline to the end of the study period in Anthropometry (weight).
Change from baseline to the end of the study period in Anthropometry (height)	Baseline to week 12	Change from baseline to the end of the study period in Anthropometry (height).
Change from baseline to the end of the study period in Anthropometry (BMI)	Baseline to week 12	Change from baseline to the end of the study period in Anthropometry (BMI).
Change from baseline to the end of the study period in use of rescue medication for pain	Baseline to week 12	Change from baseline to the end of the study period in use of rescue medication for pain. Participants will be allowed to use a rescue medication as needed, with use documented via participant diaries including date, time, dosage, reason for use. Data will be analysed based on total usage, frequency, and the proportion of participants requiring rescue medication.
