Randomized Controlled Trial
Duration and onset of effect of incobotulinumtoxina for the treatment of blepharospasm in botulinum toxin-naïve subjects.
Blepharospasm is a focal dystonia whereby excessive eyelid muscle contractions cause involuntary eye closure. Botulinum neurotoxin type A (BoNT-A) injections are an approved treatment. This randomized placebo-controlled trial (NCT01896895; EudraCT number 2012-004821-26) assessed the efficacy, safety, and treatment effect duration of incobotulinumtoxinA (Xeomin, Merz Pharmaceuticals GmbH), a BoNT-A formulation without complexing proteins, in BoNT-A-naïve adults with blepharospasm. ⋯ Subjects reported an effect onset from 5 days after injection lasting up to 20 weeks (maximum observation period). Data indicate that incobotulinumtoxinA re-treatment of blepharospasm may not be required at fixed 12-week intervals and provide evidence for a patient-tailored approach.

Randomized Controlled Trial
Clinical development and evaluation of a VEGF-D assay in plasma from patients with metastatic colorectal cancer in the RAISE study.
Vascular endothelial growth factor (VEGF)-D was identified as a potential predictive biomarker for ramucirumab efficacy in second-line metastatic colorectal cancer using a research use only (RUO) assay. We describe results with a new assay for detecting VEGF-D in human plasma. ⋯ In patients with high VEGF-D, ramucirumab demonstrated a greater improvement in OS and PFS vs placebo; however, baseline VEGF-D level was not predictive of ramucirumab OS benefit using VEGF-D assay for IUO. The RAISE intent-to-treat results remain valid.

Randomized Controlled Trial Observational Study
Effectiveness and tolerability of the thyme/ivy herbal fluid extract BNO 1200 for the treatment of acute cough: an observational pharmacy-based study.
Efficacy and safety of an oral thyme/ivy syrup for the treatment of acute cough was previously demonstrated in a randomized clinical trial. Here, we present real-life data from a pharmacy-based, observational study on the effectiveness and tolerability of another thyme/ivy combination (BNO 1200, Bronchipret drops). ⋯ Patients with acute cough taking BNO 1200 had a significant reduction in BSS, cough severity and improvement in HRQoL confirming RCT data with the syrup formulation. BNO 1200 was well tolerated.
