No one can reverse transactions, your only hope it to have proof of the hack and contact an exchange when the coins go to one.
Do you know how you were hacked?
Thats why it is very important to stay active and be careful about your wallet and the security of your investment, dont share about your coin with anyone as one of my friend kept on sharing about key and coin with close friends so he got hacked and it was all his own mistake, it is irreversible if the hacker change the private key, so better be careful and never trust anyone.
