ATTEST 2 aims to test tenecteplase in a large clinical trial to establish whether it is a better drug than alteplase for use in thrombolysis. This will involve a large number of hospitals in the UK, and possibly overseas. People who are considered suitable for thrombolysis will be allocated at random to receive either the current standard treatment with alteplase, or tenecteplase, and will be followed up for the first 90 days to measure the effects on recovery.
Even if there are no significant differences between between the two drugs, tenecteplase is less expensive and much easier to give to patients than alteplase, needing a single injection only. Alteplase has to be given as an injection followed by a longer injection over an hour. This advantage of tenecteplase alone would have worthwhile benefits to the patient.
