Insights into early stage of antibiotic development in small- and medium-sized enterprises: a survey of targets, costs, and durations
Abstract
Background: Antibiotic innovation has dwindled to dangerously low levels in the past 30 years. Since resistance
continues to evolve, this innovation deficit can have perilous consequences on patients. A number of new
incentives have been suggested to stimulate greater antibacterial drug innovation. To design effective solutions, a
greater understanding is needed of actual antibiotic discovery and development costs and timelines. Small and
medium-sized enterprises (SMEs) undertake most discovery and early phase development for antibiotics and other
drugs. This paper attempts to gather a better understanding of SMEs’ targets, costs, and durations related to
discovery and early phase development of antibacterial therapies.
Methods: DRIVE-AB, a project focused on developing new economic incentives to stimulate antibacterial innovation,
held a European stakeholder meeting in February 2015. All SMEs invited to this meeting (n = 44) were subsequently
sent a survey to gather more data regarding their areas of activity, completed and expected development costs and
timelines, and business models.
Results: Twenty-five companies responded to the survey. Respondents were primarily small companies each focusing
on developing 1 to 3 new antibiotics, focused on pathogens of public health importance. Most have not yet
completed any clinical trials. They have reported ranges of discovery and development out-of-pocket costs that appear
to be less expensive than other studies of general pharmaceutical research and development (R&D) costs. The duration
ranges reported for completing each phase of R&D are highly variable when compared to previously published
general pharmaceutical innovation average durations. However, our sample population is small and may not be fully
representative of all relevant antibiotic SMEs.
Conclusions: The data collected by this study provide important insights and estimates about R&D in European SMEs
focusing on antibiotics, which can be combined with other data to design incentives to stimulate antibacterial
innovation. The variation implies that costs and durations are difficult to generalize due to the unique characteristics of
each antibiotic project and depend on individual business strategies and circumstances.
