Create regex pattern to exclude a string

Question

I want to create a regex pattern to allow all the string with: gallery-a

or strings which start with gallery-a than a white space and after each string is accepted except clip-a.

Examples:

gallery-a ACCEPTED
gallery-a kfjrgrgl elrgkelk ACCEPTED
gallery-a clip-a NOT ACCEPTED

I tried with ^gallery-a((?!clip-a).)*$ but it doesn't work.
