  We continue to search for LBV stars in galaxies outside the Local Group. In
this work, we have investigated four luminous stars in NGC 4449. Multiple
spectral observations carried out for J122810.94+440540.6, J122811.70+440550.9,
and J122809.72+440514.8 revealed the emission features in their spectra that
are characteristic of LBVs. Photometry showed noticeable brightness changes of
J122809.72+440514.8 ($\Delta I=0.69\pm0.13^m$) and J122817.83+440630.8 ($\Delta
R=2.15\pm0.13^m$), while the variability of J122810.94+440540.6 and
J122811.70+440550.9 does not exceed $0.3^m$ regardless of the filter. We have
obtained estimates of the interstellar reddening, photosphere temperatures, and
bolometric luminosities $\log(\text{L}_\text{Bol}/\text{L}_{\odot}) \approx
5.24-6.42$. Using the CMFGEN code, we have modelled the spectrum of the cold
state of J122809.72+440514.8 ($T_{\text{eff}}=9300\,$K) and have obtained
possible value of the mass loss rate $\dot{M} =
5.2\times10^{-3}\,M_{\odot}\,yr^{-1}$. Based on the observational properties,
J122809.72+440514.8 and J122817.83+440630.8 were classified as LBVs, while the
other two stars were classified as LBV candidates or B[e]-supergiants
candidates
