      I don't want to be a buzz kill, but I wouldn't count on it. If we are lucky we can see the results published late september this year. I think it has been discussed thoroughly in earlier posts.

      Hi. The trial is impacted by COVID19, but it is not clear if that will delay the timeline. It may limit how large the population is in the trial, and what aspects of the data they can use, or at least apply to the whole population of participants. Right now, they cannot have participants come into the lab, which is the largest issue. Folks that are still on devices are asked to still use them. They are still sending TFI / THI surveys weekly to those on devices and in the washout period. They cannot measure pitch, MML, frequency, loudness etc as they do that in-lab in a controlled soundproof booth. I do think they are figuring out how they can use what they have in various forms. It's anyone's guess as to when they can have people back in the lab.

      I would not expect any report before late Q3, 2020.

      I believe it will impact some of the details of the trial, but not the grand picture. They will still eventually be able to measure MML / loudness which can serve as the basis of a comparison, and TFI / THI scores will certainly also be a good indicator especially if the reduction is large.

      Thanks for the info. Since you seem well informed on the subject, do you know or could you guess what part of the trial population until this point has been affected because of the lockdown?

      I know they were just about done recruiting, which means they were close to their target population at least starting if not fully completed. This is good news because even if a portion dropped off, they likely have a lot of data. Specific numbers, I’m not sure, but I do think they’ll have enough to study and publish. It won’t be as large as expected but it will be enough. And they may be able to draw broader conclusions by augmenting the core data with some of the less compete subjects data too.

      I am in the study and sharing what’s I have learned about the trajectory of their work through their direct communications about COVID.

      I imagine you have a NDA, but I have to ask whether you have any hope to share with us. I think we could all use a good shot of hope right now. Did it help you?

      Since he has an NDA why do you ask then? He already had the courtesy to give us useful information about the current situation. It's only a couple of months time till the results of the study come out. Let's not try to jeopardize his or anyones involvement in it.

      FWIW I just got a message to say they closed the study... I had asked them about it but then my teen got the pneumonia and things have been nuts.

      So I missed the deadline... which they never mentioned... so bummed.

      Hey there - I would absolutely hate to give you my one, isolated, anecdotal (because no one has the data available) perception of this study and the device's effect on my tinnitus. I'd also hate to say anything to compromise the study.

      What I will say is this:

      I personally believe, based on everything I know about the currently-available technology, devices in the pipeline, and trials on related technologies (U Mich, Lenire, U Minnesota, other folks like Vanneste who is looking at the Vagus Nerve among others), that bimodal stimulation has a therapeutic place in combating tinnitus. I believe that we are just at the surface of understanding the full capabilities of this science and its clinical applications, and that in the next years we will see tremendous advances in the effectiveness of bimodal stimulation based on the learnings from all of the various data being collected from in-market and in-pipeline therapies, and from the beneficial forces of market competition.

      I also believe that the research team at U Michigan is top notch and is extremely dedicated to this project for all of the right reasons. Hopefully that helps.

      Stay safe and take care.

      You mean you couldn't use pillows sleeping on your back? Mine was the same. I went to a chiro that uses a "Y strap" (go to YouTube and search) and it helps my neck with range of motion, but not my tinnitus.

      I have a memory foam pillow now and it makes a huge difference for my neck while sleeping. Doesn't help tinnitus at all though.

      You might be in the sham treatment arm so even if would be negatives it would not matter.

      I did small computation based on https://stm.sciencemag.org/content/scitransmed/10/422/eaal3175.full.pdf

      They said "Tinnitus reduction reached an average of 12.2 dB in the fourth week of active treatment. Of the 20 participants tested, 2 reported complete elimination of their tinnitus toward the end of the active treatment period."

      I interpreted from the figure below that those "two" had reduction of 49dB and 47dB. Given that we know the end results of those "two" super responders how much is the average reduction of the rest of the 18 patients. Turns out it is 8.22 dB which is still more than any of the sham treatment weeks (figure 6 a in the paper)

      If you remove the outliers I don't think this plot looks much better than Lenire, TBH. Not really encouraging the way the sham results are almost identical with actual active treatment--strongly implying placebo.

      I have to disagree. Even after removal of "the super two" the treatment shows benefits. See figure.

      Also Lenire paper (if you are referring to this one [1]) had no sham group. Simulation took 10 weeks in Lenire paper vs. 4 weeks.

      [1] https://www.neuromoddevices.com/con...dvancement/phase-i-safety-and-feasibility.pdf)

      Overall Shore's results appears much much stronger. Will it cure us all? Probably not but if 10% are totally cured and others get some benefits then it is already the best result tinnitus world has seen outside of maybe Benzos or Trobalt that have very serious side effects.

      I'd like to see similar result data for Minnesota. @kelpiemsp's testimonial made me think that was the most promising of all.

      Also how do they figure out the decibel reduction in these cases? What is the difference between active and active washout?

      THI can be a sloppy way to get results from a study. Somedays my THI is around 40 and other days around 20.

      I asked Susan Shore via e-mail if her treatment is for somatic tinnitus only, and this is what I received: 'Regarding somatic tinnitus, that is the kind we have been researching, but it could be that our treatment is also effective for those who cannot modulate'.

      It seems lack of somatic elements will not exclude one from being treated.

      You'd think by now with so many people asking her about this focus she'd think about broadening things. Having to respond by "um, maybe it will work" is frustrating.

      I asked the same months ago and she said "it might work but we don't know".

      I think that she just doesn't want to kill our hope.

      I'm a layman and I don't understand why they cannot test the device on 3 or 4 people who don't have somatic tinnitus and tell us the result (as an anecdote).

      This is what she replied to me a month ago:

      Concerning our current pivotal clinical study, we are making excellent progress, but my staff and I must refrain from making projections about time to market. Whether for drug or for device, pivotal studies are designed to carefully and deliberately assess safety and efficacy in an appropriate number of patient-subjects. On completion of the study, the FDA will then independently assess the data and then make a determination concerning clearance. Because even we are not able to see the study results during the course of the study (this is part of what is a ‘blinded study’), we must wait, like everyone else, for the conclusion of the study and its findings. I regret not being able to provide clearer guidance, and am hopeful that we may have good news toward the end of 2021.
