This paper is a contribution to the study of 2-designs admitting a flag-transitive automorphism group. We prove that if D is a non-trivial non-symmetric 2-(v,k,λ) design with (r,λ)=1 and G=PSL(3,q) acts flag-transitively on D, then up to isomorphism D is a unique 2-(8,4,3) design, or a unique 2-(q2+q+1,q,q1) design with q=2n.
