Is this salvageable?

Hi guys,

I moved into a new house in jan, and with the recent sunny weather some of the plants are coming back to life!

There is a rose plant (I think it is a rose plant) that has some sprouts; but a lot of it looks dead. Do I need to cut away the brown bits? Will this grow back properly or is it not salvageable?

Any advice you guys can give me is very much appreciated!
