A Baseline Score to Predict Response to Ranibizumab Treatment in Neovascular Age-Related Macular Degeneration.

TL;DR: Model-based characterization of best-corrected visual acuity time profiles of patients with neovascular age-related macular degeneration under ranibizumab or sham treatment based on 24-month observations of BCVA found that a composite score based on seven patient characteristics prior to treatment could be used to discriminate patients with predicted insufficient response to anti–vascular endothelial growth factor treatment.
Journal ArticleDOI

A hidden Markov model to assess drug-induced sleep fragmentation in the telemetered rat

TL;DR: A Markov model was developed to consider the high correlation in the data and quantitatively compared sleep disturbance in telemetered rats induced by methylphenidate and of a new chemical entity (NCE), showing that both compounds induce sleep fragmentation with methyl phenidate being fivefold more potent compared to the NCE.
Journal ArticleDOI

PKPD and cardiac single cell modeling of a DDI study with a CYP3A4 substrate and itraconazole to quantify the effects on QT interval duration.

TL;DR: The C-QT model for basmisanil can be used to derive the QT interval corrected changes in heart rate (QTc) and thus inform cardiac safety strategy in later development without the need for a separate, dedicated study.
Journal ArticleDOI

Population pharmacokinetic analysis of RO5459072, a low water-soluble drug exhibiting complex food–drug interactions

TL;DR: The population PK model supported that dissolution- and solubility-limited absorption from the proximal and distal intestine alone explains the non-linear PK of RO5459072 in fasted state and the linear PK in fed state.
