On OxygenOS (based on Android 5.2) I've mixed up the two solutions provided by Pilot_51.

First I've used run-as to gain access on /data/data/package.name/databases from here I wasn't able to copy directly on /sdcard/ hence I changed the permission of the file. After that I've exited from run-as mode and used cp to copy the file in /sdcard/ storage. Eventually I was able to use adb pull

$ adb -s  shell
$ run-as package.name
$ chmod 666 databases/dbname.db
$ exit
$ cp /data/data/package.name/databases/dbname.db /sdcard/dbname.db
$ exit
$ adb pull /sdcard/dbname.db ./dbname.db
