Sovaldi

[James10500]

Can you please tell me what the trial name was for this drug?

Clinical study listings may use one or more names for the same investigational drug. All investigational drugs(a compound shipped to investigators for study uses not FDA approved) have a registry name(drug company initials) and an assigned number,
In early development, an investigational drug may be called by its chemical type. The investigational drug may also have what's called a generic or compound name. (this usually happens during the trial phases early success probably influences when)

FYI if interested
Where Drug Names Come From
Behind every generic name lies a specific process

For Sovaldi
1 Pharmasset developed the investigational drug PSI-7977
2 Gilead bought Pharmasset and renamed it to GS-7977
3 Gilead generic named sofosbuvir
4 Gilead trademarks brand name Sovaldi

Tip How to Use Advanced Search
http://clinicaltrials.gov/ct2/help/how-find/advanced
Use AND, OR, NOT, and parentheses to create more complicated search expressions.

(Sovaldi OR sofosbuvir OR GS-7977 OR PSI-7977)
62 studies found  
60 studies found for:Sovaldi OR sofosbuvir OR GS-7977
56 studies found for: Sovaldi OR sofosbuvir

Just PSI-7977 44 studies found  
Just Sovaldi 56 studies found
Just GS-7977  44 studies found
Just  sofosbuvir 56 studies found

In this case you would probably only use GS-7977 OR PSI-7977 to search for older studies when a drug has a generic and brand name.
