Remark 4.4.1.10. Let $F: \operatorname{\mathcal{C}}\rightarrow \operatorname{\mathcal{D}}$ and $G: \operatorname{\mathcal{D}}\rightarrow \operatorname{\mathcal{E}}$ be isofibrations of $\infty $-categories. Then the composition $G \circ F$ is also an isofibration of $\infty $-categories (for a more general statement, see Remark 4.5.5.13).
