By 2027 the sales of biologics are predicted to surpass the aggregate sales of small molecule drugs, with US$120 billion more sales and making up 55% of all drug sales. This is a positive aspect for Patrys (PAB: $0.022), an antibody therapeutics company, according to CEO James Campbell. However, small molecule drug sales are still expected to increase by around 50% over this period driven by CNS therapy product sales.
