Study Overview
=================
Brief Summary
-----------------
The goal of this observational study is to understand and compare an alternative model of care in comparison to the usual model of care in include male and female participants ≥18 years of age with a history of ASCVD (hear and blood vessels diseases) or high-risk participants who have elevated bad cholesterol (LDL-C ≥1.8 mmol/L). The alternative model of care includes telephone support calls from a study nurse (after visits 1,2 and 4) and text messages to your mobile phone with healthy heart information. The main question it aims to answer is to understand and compare an alternative model of care in comparison to the usual model of care by evaluating the study participants bad cholesterol values after 180 and 365 days of the study. Each participant will take their medications as per usual care but may have the addition of Inclisiran, 284 mg 1.5 ml liquid in a single-use prefilled syringe for under skin administration. In accordance with the current medical practice guidelines for treating heart related conditions, inclisiran and its product information will be made available for use in both care models. All the participants who decide to take part in this study will be requested to do the following: Answer any questions from the study doctor or the study staff as accurately as possible when asked about changes in health status, medications, heart health, visits to other doctors or hospital admissions, planned surgery, even if they think none of these are related to the study. Study doctor will be able to inform them of which medications you can and cannot take as part of this study. To use mobile phone to receive text messages and/or questionnaires as proposed in the new model of care. Advise the study doctor if they plan to move away from the geographical area where the study is being conducted during the study period. Take the medications for cholesterol lowering treatment (such as a statin and/or ezetimibe) that are prescribed by the study doctor. Tell the study doctor or study staff as soon as possible about suspected participant / participant partner pregnancy. Tell the study doctor or study staff if they change their mind about taking part in the study. Attend all the visits (screening visit, visits 1, 2, 3, 4 and visit 5). Provide all the information that will enable the study team to contact them, i.e., inform the study staff if contact details change, provide contact details of a family member, etc.

Detailed Description
-----------------
ASCVD remains a significant burden in the Australian population. Moreover, based on recent local data, it is clear that there are still opportunities to improve the management of this condition in Australia. In collaboration with leading experts in the field, analysis of the gaps in management of cholesterol in Australia has been undertaken. Key areas identified include Lack of regular lipid testing in general practice, Limited access to full range of management tools, current therapies aren't achieving clinical guidelines and poor medication adherence. To address these pain points, the ASCERTAIN study will implement a new model of care that has been co-created with leading cardiologists in Australia and feedback has been provided by a General Practitioner (GP) Advisory Committee. As the primary purpose of this study is to assess the impact of a new model of care compared to usual care, inclisiran and its approved Product Information will be made available in both arms to be used as per the treating physician's discretion. Participants taking part in this study will receive maximally tolerated statin and/or ezetimibe therapy with or without other LDL-C lowering therapies as per the treating physician's discretion. The primary clinical question of interest is: What is the effectiveness of a new model of care implementation strategy compared to usual care in patients who have not reached their LDL-target? In the usual care arm: 1- The GPs will be educated on the European Society of Cardiology (ESC) guidelines and Guideline Directed Management therapy (GDMT) In the new model of care arm - The GPs will be educated on the ESC guidelines and Guideline Directed Management therapy (GDMT). The Participants enrolled in this arm will be receiving monthly short message service (SMS) messages with regards to regarding cardiovascular health and appointment reminders (low touch engagement nudges). In addition, Participants will receive telephone-based support calls from a study nurse trained in motivational interviewing. These telephone calls will cover diet, exercise, medication, and where necessary smoking cessation. A summary of any recommendations will then be sent to the primary care physician via email or letter. However, ultimately the primary care physician is responsible for the management of their patient. The study will include male and female participants ≥18 years of age with a history of ASCVD (coronary heart disease, ischaemic cerebrovascular disease or peripheral arterial disease) or ASCVD-risk equivalents who have elevated LDL-C (≥1.8 mmol/L). A total of approximately 600 participants will be included in the study and will be randomised in a 1:1 ratio at approximately 20 sites across Australia. For the purposes of defining the ASCVD-risk equivalent group, the Guidelines for the Management of Absolute Cardiovascular Disease Risk (2012) in Australian adults will be used. As per these guidelines, the online calculator www.cvdcheck.org.au (which is based on the Framingham Risk Equation) will be used to calculate an individual's estimated 5-year absolute CVD risk. High risk corresponds to >15% probability of CVD within the next 5 years. As this study will utilise Electronic Health Records (EHR), only clinics using Medical Director (MD) Clinical software will be able to participate in this study. Potential sites may be identified by running a search of the practice databases. From a recruitment and practicality perspective, in the first instance, those clinics that have a high volume of potential patients who meet the eligibility criteria will be considered. Additional formal feasibility assessment will be completed by the Sponsor to ensure clinics are suitable for participation in the study. Study sites may receive a list of patients who could qualify for the study. This list will be generated by a search of the practice database running a query for patients that satisfy the inclusion criteria. Alternatively, the sites may identify patients who could qualify for the study independently. The study sites will contact participants who meet the eligibility criteria. Patient Reported Outcomes (PROs) will be completed by the participant electronically. Participants will receive a link to the questionnaire via text message or email. The analysis will be performed at the end of the study, after the data for all participants are available. Unless otherwise specified, all statistical tests will be conducted against a two-sided alternative hypothesis, employing a significance level of 0.05. Efficacy, safety, and other data will be summarised. For continuous variables, summary statistics (mean, standard deviation, median, interquartile range, minimum, and maximum) at each time point and for change from baseline to each time point will be reported by study arm. For discrete variables, frequency counts and percentages at each time point will be reported by study arm.
