We study the medium modification factor I_pp within the light-cone path integral approach to induced gluon emission. We use parametrization of the running coupling α_s(Q,T) which has a plateau around $Q\sim \kappa T$ . We calculate I_pp with no free parameters using κ fitted to the LHC data on the nuclear modification factor R_AA. We find that the theoretical multiplicity dependence of the ratio $I_{pp}/\langle I_{pp}\rangle$ for 5.02 TeV pp collisions agrees reasonably with the recent preliminary data from ALICE [ALICE_Ipp].
