I have no idea. It is no longer a safety issue, I think, but they are not sure about dosage, frequency, duration, whether in mono or combination, and types of patients. Their previous results were very encouraging and I am sure they will find the right combination.
Just my opinion.
What does a 2/3 trial seek to establish?
Thanks.
A typo, the sentence should read:
The candidate vaccine is scheduled to enter into a pivotal phase 2/3 clinical trial in Asia in late 2014.

It seems the results of Phase II would be promising and then ABIVAX agreed to invest and colloborate with CIGB in order to carry out Phase IIb and III.
