For some time, the principal engine of Gilead’s prosperity has been its work with the affliction known as HIV. In particular, a regimen called Biktarvy has become widely prescribed, a testament to its efficacy, though efficacy alone does not guarantee unending success. While the growth in Biktarvy’s sales has not been exceptional – a modest six percent increase in the last year – it has been sufficient to sustain the company, even in the face of vigorous competition and the diminishing returns from its earlier efforts with therapies for other maladies, notably a preparation for the recent pestilence. The total revenue for the third quarter reached $7.8 billion, a figure that, while substantial, reveals a company navigating a landscape of diminishing opportunities. Excluding the aforementioned pestilence therapy, the increase was a mere four percent – a subtle indication that reliance on past triumphs may not be a path to lasting growth.
