The existence of massive galaxies (e.g. M > 1011 Msun) at high redshift (z>3-4) is strongly debated. We present the first results of a study aimed at searching for massive, red, non-dusty galaxies at high-redshift (i.e. z>3) in the GOODS-N field (Great Observatories Origins Deep Survey North) by means of deep optical, near-infrared and mid-infrared imaging, with a sample selected at 4.5 \u3bcm IRAC band (m4.5<23, AB system). For each galaxy we performed SED fitting analysis to estimate the photometric redshifts and the main physical and evolutionary properties. We found some promising candidates at redshift z>3, and we present here a few examples of their best-fit SEDs
