Most interesting take away I got from the Q&A: In the phase I trial, 6 of the patients in the FX-322 group had moderate to moderately severe SNHL, and the other 9 had mild SNHL. The 4 individuals in this group that had significant improvements in their hearing were in the severe SNHL group, and all 6 in the severe SHNL group had improved hearing (it's just that only 4 were statistically significant).
So it sounds like this drug, at least with the phase I dosing and delivery, will benefit people with severe hearing loss. Hopefully the increased dose will change things, and hopefully the delivery mechanisms will improve. It'll also be interesting to see how hearing improves over time since they're measuring the individuals for a longer period of time. Maybe the people with moderate hearing loss will also improve, it'll just take more time for the effects to be noticed. Still, I was glad to hear everyone with severe hearing loss improved. If this drug is effective, it would make the most sense that that group would improve the most.
