If I understand correctly, I agree that they won't come out and make a blanket claim that FX-322 treats tinnitus. Meaning, tinnitus in the broad sense of "ringing in the ears," without disclosing the cause.
They may however begin to comment on how noise-induced hearing loss sometimes also causes tinnitus.
They may also be able to draw specific correlations between their data, which if statistically significant, they can make more specific claims to FX-322 treating tinnitus as a symptom of hearing loss. Or treating hearing loss, or tinnitus and thereby improving quality of life.
For example, if significant:
Overall significant improvements in primary endpoints positively correlate with a reduction in TFI score, and increase in QOL measure.
A stepped improvement in primary endpoints and stepped reduction in QOL measure. For example: 1 dose population saw an average of 7 point TFI reduction, 2 dose: 14 point, 4 dose: 28 point.
With this type of data, if statistically significant, it provides enough evidence that regenerating inner and outer hair cells is connected to treating tinnitus when the condition is acquired SNHL. At that point, they can make certain claims.
I can certainly see the general public thinking, "oh yay this will fix my tinnitus" and they will need to consult their doctor at that point to understand whether their tinnitus is a symptom of SNHL or something else.
