A question about SPI-1005 phase 2 data

Does anyone remember if the results of this drug in phase 2 improved hearing?

I no longer remember if it only stopped the vertigo or if it also had other improvements. I am not only interested in the possible hearing improvement when they sell it, but because then we can deduce that although years have passed since we lost hearing, the hair cells are still there with some chance of recovering. And this also opens the hope that other future drugs can partially restore hearing.

I'm talking about helping half-dead hair cells, not about future stem cell regenerative therapies. For these there are still years to go, probably five years, but a possible therapy that saves the hair cells that are not yet dead could be something closer.
