Randomized Controlled Trial
Single inhaler triple therapy (FF/UMEC/VI) versus FF/VI and UMEC/VI in patients with COPD: subgroup analysis of the China cohort in the IMPACT trial.
Chronic obstructive pulmonary disease (COPD) is becoming a leading cause of morbidity and mortality in China. In the IMPACT trial, fluticasone furoate[FF]/umeclidinium[UMEC]/vilanterol[VI] single-inhaler triple therapy demonstrated lower rates of moderate/severe exacerbations than dual therapy with FF/VI or UMEC/VI in patients with symptomatic COPD and a history of exacerbations. This analysis investigates the China cohort and its consistency with the overall ITT population. ⋯ Single-inhaler triple therapy with FF/UMEC/VI versus FF/VI or UMEC/VI reduced the rate and risk of exacerbations, and improved lung function and health status in the China cohort similar to the overall ITT population. No new safety signals were identified.

The results from basket trials utilized to gain regulatory approval of tumor-agnostic therapies can be difficult to interpret without the context of a comparator arm. We describe the role and efficacy of histology-based treatments to provide a historical comparison with larotrectinib. ⋯ Utilizing larotrectinib as a case example across these types of historical comparisons shows that larotrectinib provides positive efficacy outcomes in TRK fusion cancer across tumor histologies known to harbor NTRK gene fusions that may be preferable to historical treatments.

Regulations for new drug approvals require stringent safety testing and efficacy trial programs. The approval process for generic drugs, however, is significantly streamlined. Bioavailability data can substitute for new rounds of efficacy trials, thereby both decreasing time to approval and reducing the costs required for new studies. ⋯ Long-acting, inert delivery vehicles for the drug have become available for the same indications. Safety and bioavailability profiles of the long-acting products are the same or improved over the parent product. A review of the long-acting drugs provides compelling evidence to recommend that generic drug-controlled release products may be eligible for alternative regulatory programs.

Six prospective real-world studies of antihypertensive treatment with valsartan-centric regimens were pooled to: (1) examine the effectiveness of ∼90 days of second- or later-line valsartan treatment in hypertensive patients with known comorbidities; and (2) identify physician- and patient-related determinants associated with systolic (SBP) and diastolic blood pressure (DBP) outcomes in these patients. ⋯ Valsartan-centric regimens have significant BP lowering benefits in this pooled sample of patients with known comorbidities. Many observed determinants of BP outcomes are modifiable or manageable.

Observational Study
The Rapid Mood Screener (RMS): A novel and pragmatic screener for bipolar I disorder.
Depressive episodes and symptoms of bipolar I disorder are commonly misdiagnosed as major depressive disorder (MDD) in primary care. The novel and pragmatic Rapid Mood Screener (RMS) was developed to screen for manic symptoms and bipolar I disorder features (e.g. age of depression onset) to address this unmet clinical need. ⋯ The pragmatic 6-item RMS differentiates bipolar I disorder from MDD in patients with depressive symptoms, providing real-world guidance to primary care practitioners on whether a more comprehensive assessment for bipolar I disorder is warranted.
