They are trying to achieve a sustainable solution ("semi-cure/long term suppression") I would say. Not a cure, but a structural lowering of tinnitus symptoms.
The goal is inducing neuroplasticity (long term/permanent changes in the brain), not short term suppression. You are teaching cells to react differently and if I understand correctly you hope cells remain firing differently.
If they didn't strive for a cure, why do a protocol with 1x 60 days treatment with a follow-up of 38 weeks? What do you expect to find in week 37/38 so late in? If this was designed as a maintenance - continuous treatment, you would expect a different protocol over 38 weeks - 45 days treatment, 20 days rest, 45 days treatment, 20 days rest etc with several subgroups/timings to find the ideal protocol, duration etc. Not one group with one treatment session.
No, I don't think it will delay FDA, and no, I don't think it will delay production either but the treatment protocol might need optimization on the go.
