Includes three categories, investigator-initiated studies, supportive collaborative studies and GSK-sponsored studies. Investigator-initiated studies were initiated, developed, designed and conducted by external investigators who assumed sole responsibility for the study, and GSK’s only involvement was financial support via an independent grant. Supportive collaborative studies were conducted by external investigators who assumed sole responsibility for the study but involved greater collaboration with GSK, for aspects of study design, data interpretation or provision of study-specific product (± matching placebo) free of charge. GSK-sponsored studies are those in which GSK were fully responsible for the design, initiation and funding of the study.

Clinical study was initiated, developed, designed and conducted by external investigators who assumed sole responsibility for the study.

Clinical study was supported financially or sponsored by a non-GSK pharmaceutical company.
