We study new supergravity solutions related to large-$N_c$ ${\cal N}=1$supersymmetric gauge field theories with a large number $N_f$ of massiveflavors. We use a recently proposed framework based on configurations with$N_c$ color D5 branes and a distribution of $N_f$ flavor D5 branes, governed bya function $N_f S(r)$. Although the system admits many solutions, underplausible physical assumptions the relevant solution is uniquely determined foreach value of $x\equiv N_f/N_c$. In the IR region, the solution smoothlyapproaches the deformed Maldacena-N\'u\~nez solution. In the UV region itapproaches a linear dilaton solution. For $x<2$ the gauge coupling $\beta_g $function computed holographically is negative definite, in the UV approachingthe NSVZ $\beta $ function with anomalous dimension $\gamma_0= -1/2$(approaching $-3/(32\pi^2)(2N_c-N_f)g^3$)), and with $\beta_g \to-\infty $ inthe IR. For $x=2$, $\beta_g$ has a UV fixed point at strong coupling,suggesting the existence of an IR fixed point at a lower value of the coupling.We argue that the solutions with $x>2$ describe a "Seiberg dual" picture where$N_f-2N_c$ flips sign.
