  A combination of measurements sensitive to the CKM angle $\gamma$ from LHCb
is performed. The inputs are from analyses of time-integrated $B^{+}\rightarrow
DK^+$, $B^{0} \rightarrow D K^{*0}$, $B^{0} \rightarrow D K^+ \pi^-$ and $B^{+}
\rightarrow D K^+\pi^+\pi^-$ tree-level decays. In addition, results from a
time-dependent analysis of $B_{s}^{0} \rightarrow D_{s}^{\mp}K^{\pm}$ decays
are included. The combination yields $\gamma = (72.2^{+6.8}_{-7.3})^\circ$,
where the uncertainty includes systematic effects. The 95.5% confidence level
interval is determined to be $\gamma \in [55.9,85.2]^\circ$. A second
combination is investigated, also including measurements from $B^{+}
\rightarrow D \pi^+$ and $B^{+} \rightarrow D \pi^+\pi^-\pi^+$ decays, which
yields compatible results.
