We report on a recent calculation of the properties of the DNN system, a charmed meson with two nucleons. The system is analogous to the system substituting a strange quark by a charm quark. Two different methods are used to evaluate the binding and width, the Fixed Center approximation to the Faddeev equations and a variational calculation. In both methods we find that the system is bound by about 200 MeV and the width is smaller than 40 MeV, a situation opposite to the one of the system and which makes this state well suited for experimental observation.
