      I've attached the presentation from Auris Medical's "Key Opinion Leader" meeting held today (June 14). They seem pretty confident (though they were talking to investors....) and have officially named AM-101 as "Keyzilen".

      There are four parts to the presentation. The first is an introduction; the second is a detailed discussion of the TACTT trials including endpoints required for regulatory approval; the third is a discussion by Hinrich Staecker about inner ear tinnitus; and the last is a market analysis.

      The discussion of requirements for regulatory approval are interesting. They will need to show significant and clinically meaningful improvement over placebo in tinnitus loudness and the TFI for TACTT2. Also of note: the randomization was 3 to treatment for each 2 to placebo.

      Based on the numbers in the PowerPoint, Auris Medical expects to generate drug revenues in the amount of $3000 an ear, not including ENT injection costs.

      Does this mean AM-101 works?

      Interesting presentation, so why they don't have any data on how many people got cured?

      This 2015 article say:

      "Auris is in late-stage trials of AM-101, a derivative of the anesthetic ketamine, which it hopes will dampen the aberrant signaling in the auditory nerve that is perceived as tinnitus. In a midstage trial, the drug, injected into the middle ear, was not more effective overall than a placebo. But a subset of patients whose tinnitus was caused by trauma or infection said the drug made the sound in their ears softer, less annoying and less disruptive of sleep."​

      Investors appear to be cautious given the challenges. Auris Medical went public on NASDAQ in August at $6 a share, using the trading symbol EARS. The stock is now trading at about $4.

      Keep an eye on that stock. I think it's at 4.75. If it gets about 7 people are starting to believe, but they also have a hearing loss drug. I heard the Department of Defense is a big investor, so that's hopeful.

      I was one of the test subjects, first they gave me the test version where they did not know if it was the real medicine or placebo. Later on after the trial I received the real drug, sadly it did not work on me... but maybe it will work on one of you.

      I've posted about my experience before in a different thread about AM-101, and I'm curious how they are interpreting the data to show that it improved tinnitus loudness.

      After I had the first round of injections my tinnitus actually got worse, it was much louder than where it was initially.

      Over the course of several weeks the tinnitus did decrease in volume, but only back to where it had been before I had the first injection.

      I had the same experience after the 2nd round of injections, louder tinnitus after the injections and then back to where it was.

      My tinnitus never improved beyond where it was before the trial.

      I still have tinnitus today, and sometimes think it's a little worse. I use to wake up with a few seconds of silence, but that no longer happens. I also have developed consistent insomnia, can't sleep for more than a few hours because of tinnitus, since being in the trial.

      Another important point is that 90 days of observing patient improvements is not long enough to determine if the drug works or not. They should monitor people for at least 6 months up to a year in my opinion.

      I sincerely hope there is a treatment as some point in my life that is truly effective, unfortunately for me AM-101 is not the one.

      @ryant, do you think that these increases could be connected with the healing time your tympanic membrane needs after each injection?

      I’m not sure what caused the worsening of the tinnitus after the injection. Several other other people reported the same side effect.

      I am asking only because it's normal to have a slight increase for a few days (even weeks) due to the nature of the procedure (conductive loss due to the membrane perforation).

      If that was the case then probably we are talking about zero gains.

      I thought I would actually post positive thread for once. I imagine you're all sick of my soul draining negativity. As dark and rainy as my world may be, there is one thing the gives me hope, and that is Keyzilen (AM-101).

      The drug is currently in Phase 3 testing. It is a gel that when injected into the ear acts to suppress cochlear NMDA receptors that apparently play a role int he development of tinnitus from being acute to chronic. There are clinical trials in the US people ca take part in, but only with the first 3 months of your tinnitus. I kick myself sometimes because it means I could have stopped this during the summer when it was still "acute", but now its too late.

      It does represent hope for the future though. This drug (as well as AM-111 for Meniere's Disease) could be the gateway to some kind of chronic tinnitus treatment. More importantly, it potentially means fewer chronic sufferers in the future. The animal trials apparently involved exposing mice to a loud ambulance siren for 45 minutes to induce tinnitus. My heart goes out to those mice, cured or not.

      There link below has more information. I certainly hope this means for the rest of you, a cure is on the horizon at some point. I am skeptical i this condition can really be "cured" but I suppose suppressing the neurons needed to generate the noise is enough for me.

      Considering that AM-101 tried something very similar a year or two ago and failed, I don't think Keyzilen is going to be what we're looking for. Sorry...

      Isn't Keyzilen just the name they gave AM-101?

      People have been discussing AM-101 / Keyzilen here for several years with 2000+ messages in the thread (and it doesn't work for most of those who tried)

      Sorry if I'm missing something, but why are you speaking about it like it's a new hope?

      I'm new to tinnitus and newer to anything research related. I only recently heard about it.

      Do you know that Keyzilen is only meant to be for acute, is it with certainty that it won't work for those who have had tinnitus a long time?

      Also, the next results are expected in Feb 2018 - this could mean that this medicine will be on market by next year?
