"This is a routine action which has to happen whenever there is a potentially unexplained illness in one of the trials, while it is investigated, ensuring we maintain the integrity of the trials."

The company spokesperson also added that in large trials, illnesses will sometimes happen by chance but must be reviewed independently.

"We are working to expedite the review of the single event to minimise any potential impact on the trial timeline," the spokesperson said.

The nature and severity of illness or where the patient was not clear immediately.
