Brief Summary
People with type 1 diabetes sometimes develop heart failure which can cause symptoms like breathlessness, tiredness or ankle swelling, reduced quality of life and lead to being admitted to hospital or suffering potential fatal consequences. This trial is investigating if a tablet called sotagliflozin, can improve quality of life in people with type 1 diabetes and heart failure. In addition, this trial will also assess the safety and tolerability of sotagliflozin in this population. In previous trials that included people with type 2 diabetes and heart failure sotagliflozin was shown to improve patients' symptoms of heart failure, quality of life and reduce the chance of people with heart failure being admitted to hospital or dying. However, people with type 1 diabetes and heart failure were not included in these trials meaning that it is not known if these benefits also apply to this population. This trial aims to recruit 320 people with type 1 diabetes and heart failure symptoms in multiple sites in the United Kingdom (UK). This trial will compare the health and quality of life of participants who take sotagliflozin tablets with participants who take placebo tablets, which is a dummy tablet that looks the same as sotagliflozin. Participants will be randomly allocated to one of two groups (i.e. one taking sotagliflozin and the other the placebo) and both the medical team and participants will not know in which group each participant is until the end of the study. Participants will be in the trial for approximately 6 months and will be given sotagliflozin or placebo tablets to take 1 per day for 4 months. The trial is expected to run for a total of 26 months.

- New York Heart Association Class II-IV at screening.
- Elevated N-terminal pro-B-type natriuretic peptide (≥250 ng/L for those in sinus rhythm, ≥400 ng/L if in atrial fibrillation) or B-type natriuretic peptide (≥75 ng/L for those in sinus rhythm, ≥100 ng/L if in atrial fibrillation) within 12 months of screening.

Data Sharing
- IPD Sharing
- Will not share
Datasets of pseudo-anonymised IPD generated/analysed during the current study will be available upon request from the Chief Investigator (CI) Dr Ify Mordi (i.mordi@dundee.ac.uk) at the end of the trial (i.e. when all endpoints/outcomes have been met, key analyses are complete and results published in peer-reviewed scientific journals). Data will remain available for at least 25 years. Data will only be released for legitimate secondary research purposes, where the CI agrees that the proposed use has scientific value and will be carried out to a high standard (in terms of scientific rigour, information governance and security), and that there are resources available to satisfy the request. Data will only be released in line with participants' consent, all applicable laws relating to data protection and confidentiality, and any existing contractual obligations. No individual participant data will be released before an appropriate agreement is in place setting out the conditions of release. The agreement will govern data retention, usually stipulating that data recipients must delete their copy of the released data at the end of the planned project.
