Comparative Efficacy of Ibrutinib Versus Obinutuzumab + Chlorambucil in First-Line Treatment of Chronic Lymphocytic Leukemia: A Matching-Adjusted Indirect Comparison.

ABSTRACT:

Introduction

Ibrutinib (ibr) monotherapy and the combination of obinutuzumab plus chlorambucil (obi) are approved for previously untreated chronic lymphocytic leukemia (CLL). No trials directly comparing their efficacy are available. Therefore a matching-adjusted indirect comparison (MAIC) was performed to provide insight into their relative efficacy in terms of progression-free survival (PFS) and overall survival (OS). MAIC attempts to adjust for between-trial differences in factors known or suspected to influence treatment effects, to minimize bias.

Methods

A MAIC within a Bayesian framework was conducted using individual patient data from the RESONATE-2 study of ibr versus chlorambucil and published data from the CLL11 study of obi versus chlorambucil. Both studies were c
