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

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

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

Progression-free survival as a surrogate endpoint in myeloma clinical trials: an evolving paradigm [PDF]
Measurement of overall survival (OS) remains the gold standard for interpreting the impact of new therapies for multiple myeloma in phase 3 trials. However, as outcomes have improved, it is increasingly challenging to use OS as the primary endpoint if ...

Food and Drug Administration approvals in phase 3 Cancer clinical trials
Background Phase 3 oncologic randomized clinical trials (RCTs) can lead to Food and Drug Administration (FDA) approvals. In this study, we aim to identify trial-related factors associated with trials leading to subsequent FDA drug approvals.
