Abstract: 
We study scattering amplitudes of higher spin closed-string states off D-brane bound-states. For states in the first Regge trajectory we find remarkable simplifications both at tree level and at one loop. We discuss the high energy behavior in the Regge limit and comment on the validity of the eikonal approximation in this regime.
