The new transits have been combined with all previously published transit data for this planet to provide a new transit timing variations (TTVs) analysis of its orbit. We find no TTVs with amplitudes larger than 1.5 minutes over a four-year observation time baseline, in agreement with the recent result by Adams et al. Dynamical simulations fully exclude the presence of additional planets in the system with masses greater than 1.3, 0.4, and 0.5 M at the 3:2, 1:2, and 2:1 resonances, respectively. We also place an upper limit of about 30 M on the mass of potential second planets in the region between the 3:2 and 1:2 mean-motion resonances.
