Rivaroxaban ACS Specialist Cohort Event Monitoring Study

Status Completed

Clinical Trial Summary

Rivaroxaban is a medicine which reduces the formation of blood clots. Acute coronary syndrome (ACS) comprises a range of disorders, including heart attack and unstable angina, caused by a sudden reduction in blood flow to part of the heart muscle. This study aims to collect information on the use of rivaroxaban and its safety when used by patients for the prevention of atherothrombotic (plaque rupture leading to a blood clot) events following ACS, during the first three months after starting. This study was requested by the European regulatory body (EMA) which is responsible for the use and safety of medicines. It will last for approximately 3 years and is a national study covering the whole of England and Wales. The study aims to recruit 1193 patients who have been prescribed rivaroxaban and antiplatelet therapy and 1193 patients who have been prescribed alternative dual antiplatelet therapy for the secondary prevention of atherothrombotic events following ACS. Each patient will only be monitored for the first 13 weeks after hospital admission for ACS. Patients who choose to take part will complete a consent form. The patient's care team will be asked to complete a baseline questionnaire about the patient at the time the medicine is given and a further questionnaire up to 16 weeks later, specifically asking about the patient's experiences whilst on the medication. If anything unusual is reported during the observation period, the care team may be asked to fill out a followup questionnaire. With the patient's consent, the study team will also inform the patient's General Practitioner (GP) of their participation in the study and will ask the GP to complete an abridged questionnaire from the patient's medical records. The study team will analyse and aggregate the data, carefully protecting patient confidentiality, to classify adverse events of interest, in particular bleeding events.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
