We report evidence for B-0 -> D+D- and the first observation of the decay modes B-->(DD-)-D-0 and B-->(DD*-)-D-0 based on a sample of 152x10(6) B (B) over bar events collected by the Belle detector at KEKB. The branching fractions for B-0 -> D+D-, B-->(DD-)-D-0, and B-->(DD*-)-D-0 are found to be (1.91 +/- 0.51 +/- 0.30)x10(-4), (4.83 +/- 0.78 +/- 0.58)x10(-4), and (4.57 +/- 0.71 +/- 0.56)x10(-4), respectively. Charge asymmetries in the B-->(DD-)-D-0 and B-->(DD*-)-D-0 channels are consistent with zero.
