ACT4RHD is an Open-label, Randomised, Adaptive Platform Trial to Evaluate Novel and Repurposed Clinical Interventions for Patients With Acute Rheumatic Fever and Carditis. ACT4RHD Seeks to Determine Whether These Interventions Reduce RHD Severity at 6 Months. (ACT4RHD)
ACT4RHD: Adaptive Collaborative Trial for Rheumatic Heart Disease
The ACT4RHD trial is a multicentre, pragmatic, multi-arm, open-label adaptive platform trial addressing multiple therapeutic questions in patients with ARF and carditis. ACT4RHD aims to improve health outcomes for children and young people affected by ARF by finding treatments to reduce heart damage. The trial's Bayesian adaptive design enables multiple promising treatments to be tested at the same time. The trial will adapt by stopping treatments that are not effective sooner than traditional trials, adding new treatments as they become available, and answering research questions as soon as enough evidence has been collected. This flexibility allows researchers to identify the most effective treatments more quickly than traditional clinical trials.

Descrizione dettagliata
Background: Acute rheumatic fever (ARF) is a major health priority in lower-middle income countries (LMIC) and for Indigenous and underserved populations in high income countries including Australia and New Zealand. It is an autoimmune condition of childhood triggered by Strep A infection, leading to rheumatic heart disease (RHD). RHD affects more than 40 million people globally, resulting in approximately 310,000 deaths each year. There are currently no proven anti-inflammatory or immune modulating therapies to limit cardiac damage during ARF to prevent RHD. The only treatment is antibiotics (penicillin) given after ARF is diagnosed, to prevent recurrent streptococcal infections that drive ARF recurrences and progression of RHD.
Design: ACT4RHD is a randomized, multifactorial, open label adaptive platform trial with blinded end- point assessment. At trial launch, domains will comprise a Corticosteroid domain and an Immunomodulatory Domain. The treatment intervention in the Corticosteroid domain will include 4 to 6 weeks of corticosteroids or a no-corticosteroid control.
Treatment for the Immunomodulatory domain includes hydroxychloroquine for 12 weeks compared to a no-hydroxychloroquine control.
These are interventions are prescribed open label in addition to standard care. The primary endpoint is a 6-point ordinal scale which comprises RHD severity (measured by echocardiography), need for rheumatic cardiac surgery or death at 6 months.
Aims: The overarching aim of ACT4RHD is to alleviate suffering from ARF and reduce the prevalence and severity of RHD which arises from ARF. Trial hypotheses at launch:
- That corticosteroids administered to children and young adults with ARF affecting the mitral and/or aortic valve will be safe and will reduce valve inflammation (that is, carditis) in rheumatic fever;
- That hydroxychloroquine treatment administered to children and young adults with ARF affecting the mitral and/or aortic valve will be safe and will reduce valve inflammation in rheumatic fever;
- That reduction in carditis severity and/or duration, will be associated with reduction in valve scarring and dysfunction, measured by an echocardiographic RHD severity grade at 6 months;
- That reduction in carditis will be associated with lower RHD severity at 12 months, and with improved patient-centered outcomes;
- That the development of a durable ARF platform trial will allow several investigational products and management approaches to be tested in a robust and rigorous fashion over the coming years.
