This paper focuses on the Diophantine equation $xⁿ+p^{α}yⁿ = Mz³$, with fixed α, p, and M. We prove that, under certain conditions on M, this equation has no non-trivial integer solutions if $n ≥ ℱ(M,p^{α})$, where $ℱ(M,p^{α})$ is an effective constant. This generalizes Theorem 1.4 of the paper by Bennett, Vatsal and Yazdani [Compos. Math. 140 (2004), 1399-1416].
