A multicenter study has found that a multiplex diagnostic panel developed by Opgen Inc. can reduce the use of inappropriate antibiotic therapy by 45.1%. Opgen’s Unyvero Hospitalized Pneumonia (HPN) panel uses PCR technology that can detect 21 pathogens and 17 antibiotic resistance markers in less than five hours. During the European Respiratory Society conference, Rockville, Md.-based Opgen presented data showing that combined with antibiotic stewardship, its HPN panel decreased time on inappropriate antibiotic therapy in hospitalized patients with pneumonia at risk for Gram-negative rods.

Following two clinical trial disappointments, the newest being the phase III failure of ampreloxetine, Theravance Biopharma Inc. will restructure by laying off three-quarters of its staff and will stop developing all but two of its non-respiratory disease programs. The ampreloxetine study for treating symptomatic neurogenic orthostatic hypotension failed to meet its primary endpoint, the company announced Sept. 15. In late August, data from a phase IIb dose-finding study showed izencitinib, a gut-selective pan-JAK inhibitor for treating ulcerative colitis, failed to meet its primary endpoint.

LONDON – Breath biopsy specialist Owlstone Medical Ltd. closed a $58 million oversubscribed series D, bringing the total raised by the company since its formation in 2016 to over $150 million.
