The sum rule for charmless inclusive semileptonic B-meson decays allows a
theoretically clean and experimentally efficient determination of |V_{ub}|. The
leading twist contribution to the sum rule is known in QCD. We compute higher
twist corrections to the sum rule using the heavy quark effective theory.
