  Using the Mathisson-Papapetrou-Dixon equations together with the Tulczyjew
spin-supplementary condition, we study the circular orbits of a spinning test
particle moving in the equatorial plane of a quantum improved Rotating Black
Hole (RBH) spacetime. This background metric incorporates a position-dependent
gravitational constant $G(r)$ and its behavior determines the quantum
corrections to the properties of the Innermost Stable Circular Orbit (ISCO).
The obtained results show that the radius of the event horizon as well as the
radius of the ISCO for the quantum improved RBH are smaller than those of the
Schwarzschild or Kerr solutions.
