Yes, fillies have been among the Kentucky Derby's winners! Regret [1912 - April 11, 1934] was the first filly [female horse] to win the Kentucky Derby, in 1915, with a time of 2:05.40 minutes. Genuine Risk [February 15, 1977 - August 18, 2008] was the second filly to win the Derby, in 1980, with a time of 2:02.00 minutes. Winning Colors [February 14, 1985 - February 17, 2008] was the third and final filly to win the Derby, in 1988, with a time of 2:02.20 minutes.
Technically, a mare is defined as a female horse over the age of three. A filly is a female horse three years or younger. Since the Kentucky Derby is a race for 3-year-olds only, no mare has ever won. However, three fillies have won the Kentucky Derby: Regret (1915); Genuine Risk (1980); and Winning Colors (1988).
Winning Colors [February 14, 1985 - February 17, 2008] was the last filly to win the Kentucky Derby. The young mare finished first in the 1988 Derby. She was the third and most recent of three fillies to claim victory in the world-famous race that's held yearly at the Churchill Downs racetrack in Louisville, Kentucky.

'Legend of the East' was the nickname for Regret [1912 - April 11, 1934]. She was the first filly to win the Kentucky Derby. Her triumph took place, with a fast start and a consistently easy lead, in 1915.
A horse (cold, gelding or filly) may only run in the Kentucky Derby at the age of three-years-old. So the answer is that a horse can only run once. That's what makes it such a special win.
