Global existence for the derivative NLS equation in the presence of solitons

We prove the existence of global solutions to the DNLS equation with initial data in a large subset of $H^2(\mathbb{R})\cap H^{1,1}(\mathbb{R})$ containing a neighborhood of all solitons. We use the inverse scattering transform method, which was recently developed by D. Pelinovsky and Y. Shimabukuro, and an auto-B"acklund transform in order to include solitons.
