A review of evidence supporting amyloid beta reduction as a surrogate endpoint in Alzheimer’s disease [PDF]

open access: yesThe Journal of Prevention of Alzheimer's Disease
Alzheimer’s disease (AD) is a heterogeneous neurodegenerative disease driven by pathological depositions of proteins that accumulate over decades. Compelling genetic and neurobiological evidence suggests that amyloid accumulation in the brain initiates ...

Potential surrogate endpoint for B-cell hematologic malignancy: A systematic review and meta-analysis [PDF]

open access: yesScientific Reports
Confirming the patient benefit of progression-free survival (PFS) in B-cell non-Hodgkin lymphoma (B-NHL) and multiple myeloma (MM) has become increasingly challenging due to the improved outcomes brought by novel therapies. In parallel, the U.S. Food and

A randomised controlled trial is not a pilot trial simply because it uses a surrogate endpoint [PDF]

open access: yesPilot and Feasibility Studies, 2018
Background It has been argued that true endpoints (or ‘hard’ endpoints) for clinical trials, which are meaningful to clinicians, researchers and patients alike, are limited to those that measure health status, survival and cost.

Incorporating Covariates into Measures of Surrogate Paradox Risk

open access: yesStats, 2023
Clinical trials often collect intermediate or surrogate endpoints other than their true endpoint of interest. It is important that the treatment effect on the surrogate endpoint accurately predicts the treatment effect on the true endpoint.

Evaluating amyloid-beta as a surrogate endpoint in trials of anti-amyloid-beta drugs in Alzheimer’s disease: a Bayesian meta-analysis [PDF]

open access: yesJournal of Comparative Effectiveness Research
Aim: The use of amyloid-beta (Aβ) clearance to support regulatory approvals of drugs in Alzheimer’s disease (AD) remains controversial. We evaluate Aβ as a potential trial-level surrogate endpoint for clinical function in AD.

Appropriate Surrogate Endpoint in Drug-Coated Balloon Trials for Coronary Artery Diseases [PDF]

open access: yesFrontiers in Cardiovascular Medicine, 2022
BackgroundThe appropriateness of using late lumen loss (LLL) as a surrogate endpoint was established in drug-eluting stent (DES) studies, but it was less supportive for drug-coated balloon (DCB) trials.MethodsStudies published until 23 June 2021 were ...

Protocol for the development of SPIRIT and CONSORT extensions for randomised controlled trials with surrogate primary endpoints: SPIRIT-SURROGATE and CONSORT-SURROGATE

open access: yesBMJ Open, 2022
Introduction Randomised controlled trials (RCTs) may use surrogate endpoints as substitutes and predictors of patient-relevant/participant-relevant final outcomes (eg, survival, health-related quality of life).

A perfect correlate does not a surrogate make

open access: yesBMC Medical Research Methodology, 2003
Background There is common belief among some medical researchers that if a potential surrogate endpoint is highly correlated with a true endpoint, then a positive (or negative) difference in potential surrogate endpoints between randomization groups ...

open access: yesAnnals of Noninvasive Electrocardiology, 2021
Friedreich's ataxia is a rare degenerative neuromuscular disorder, caused by a homozygous GAA triplet repeat expansion in the frataxin (FXN) gene, with a broad clinical phenotype characterized by progressive gait and limb ataxia, dysarthria, and loss of ...
