Key result
A fixed effects meta-analysis approach provided a pragmatic solution to pooling complex and varied clinical pharmacology studies to assess QTc prolongation for regulatory submissions.
Why the study?
Does a general fixed effects meta-analysis approach effectively pool QTc interval data from heterogeneous clinical pharmacology studies to assess the difference between active drug and placebo?
Meta-Analysis
Does a general fixed effects meta-analysis approach effectively pool QTc interval data from heterogeneous clinical pharmacology studies to assess the difference between active drug and placebo?
A fixed effects meta-analysis approach is useful for pooling heterogeneous clinical pharmacology studies to evaluate drug-induced QTc prolongation for regulatory submissions.

Fixed-effects meta-analysis aids QTc regulatory assessments; extends pooling methods for heterogeneous pharmacology studies.
A diverse range of non‐cardiovascular drugs are associated with QT interval prolongation, which may be associated with a potentially fatal ventricular arrhythmia known as torsade de pointes. QT interval has been assessed for two recent submissions at GlaxoSmithKline. Meta‐analyses of ECG data from several clinical pharmacology studies were conducted for the two submissions. A general fixed effects meta‐analysis approach using summaries of the individual studies was used to calculate a pooled estimate and 90% confidence interval for the difference between each active dose and placebo following both single and repeat dosing separately. The meta‐analysis approach described provided a pragmatic solution to pooling complex and varied studies, and is a good way of addressing regulatory questions on QTc prolongation.

Webber et al. (2002) conducted a meta-analysis in QT interval prolongation. Non-cardiovascular drugs vs. Placebo was evaluated on Difference in QTc interval between active dose and placebo. A fixed effects meta-analysis approach provided a pragmatic solution to pooling complex and varied clinical pharmacology studies to assess QTc prolongation for regulatory submissions.
