  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 $\alpha_s(Q,T)$ which has a plateau around $Q\sim \kappa T$.
We calculate $I_{pp}$ with no free parameters using $\kappa$ 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 [1].
