We consider the cross section of the deep inelastic pion electroproduction on a proton target at threshold for Q(2) in the region 5-10 GeV(2). The corresponding amplitudes are described in terms of two form factors which we calculate using light-cone sum rules to leading order in QCD and including higher twist corrections. Our results suggest a considerable change from a small Q(2) region that can be treated in the soft-pion limit using current algebra. In particular, we obtain a pi(0) to pi(+) production ratio of order 1/3 and significant nucleon helicity-flip contributions.
