Vernalis reported a modest £0.6m in Tuzistra XR sales over the first four months post-launch due to the mild cough cold season. The US launch of this prescription-only (Rx), extended release (ER) cough cold medicine is the first step in Vernalis’s transition into a commercial-stage speciality pharma company, targeting a $3.5bn market opportunity. The emphasis for year one of Tuzistra XR commercialisation is operational: establishing the platform for future sales growth. However, financial performance, in particular, during its second year on the market, will be an important determinant of whether Vernalis will need to raise new funds near term.
