No cases of pseudosepsis were reported in the trial and extension.
*Preferred term with an incidence of >1 among treatment groups (safety population).
†TEAEs were reported for subjects who received EUFLEXXA in both the core and extension trials (219 of 433).
N=number of subjects in a given treatment group for the population analyzed; n=number of subjects reporting at least 1 AE within system organ class/preferred term; (%)=percent of subjects based on N. Note: Related AEs are those with trial device relationship classified as “certain,” “probably,” “possible,” or “unassessable.”
