  The spectrum of primordial perturbations obtained by calculating the quantum
gravitational corrections to the dynamics of scalar perturbations is compared
with Planck 2013 and BICEP2/{\it Keck Array} public data. The quantum
gravitational effects are calculated in the context of a Wheeler-De Witt
approach and have quite distinctive features. We constrain the free parameters
of the theory by comparison with observations.
