Drivers and Barriers to Drug Discovery: Insights from a Cross-sectional Survey
- 72 Downloads
Motivated by stagnant new drug approval rates, this study explores the drivers and barriers to drug discovery to extract policy-relevant advice.
As part of a doctoral dissertation, an online survey was administered to drug discovery experts between July and November 2017. Respondents came from patents, startup managers/founders, conference speakers, consultants, and LinkedIn profiles, contingent on finding respondent emails from a web search. Respondents ranked drivers and barriers to drug discovery and judged R&D and drug approval trends.
Pooling responses based on frequency of mentions, indicate that respondents deem “skilled R&D scientists”, “R&D investments”, and “good R&D management” as the top three drivers of drug discovery. The “depth” of specialized knowledge is mentioned more than the “diversity” of knowledge available to the discovery team. Likewise, “complex clinical trials”, “companies pursuing the same drug targets”, and “designing drug substances with a single or narrow therapeutic benefits” are top ranked barriers to drug discovery. The majority view is that R&D spending has been stagnant for the past decade. New drug approval trend is judged to be improving in the past 5 years. Ninety percent of respondents believe their responses are generalizable to other therapeutic areas, indicating instrument’s validity in capturing general drug discovery issues.
There are traces of hard and soft institutional problems, firm capability development failures, networking failures, and institutional rigidities (i.e., lock-in failures) in the drug discovery innovation system.
