Hi everybody!

Tinnitus Talk spoke with the Hough Ear Institute, a non-profit research organization that focusses on restoring hearing. They are working on two hearing regeneration treatments that could very well have benefits for tinnitus sufferers. The idea for this podcast episode came about due to our very active thread on Hough.

In this episode, we spoke with Dr. Richard Kopke and Justin DeMoss. They explain the mechanisms behind their treatments and how hearing restoration can be achieved. They take us through the different phases of research and development required to get new drugs to market, and some of the challenges faced along the way. Of course, we also touch on the topic of whether restoring hearing could cure tinnitus.

The episode includes an announcement about an exciting new partnership with pharmaceutical company Oblato to take Hough's hearing loss pill through the next phases of clinical trial and assess its potential for tinnitus.

Thank you so much to everyone involved! That was an awesome interview to hear. It really highlights how much Hough Ear Institute cares about bringing an end to hearing disorders. I rewinded this part many times: "Phase 2 for the pill by 2020". I'll have to wait for the transcript to go full on ecstatic but man did that bring a smile to my face.

Godspeed.

I'll give this a listen on my way home. Glad to hear that progress is being made.

Great job, @Hazel and all the other volunteers.

Can we start a crowdfund for the $735,000 goal of opening up NHPN-1010 to an additional tinnitus experimental arm in phase 2, @Markku?

Is this essentially the correct verbiage, @Justin De Moss?

I'd gladly shell $50 or more for this.

I'd like to add a singular donation source like this to my brochure to deliver to veterans agencies.

Without support from other tinnitus organizations, it's going to be an uphill battle to raise such significant funds. You weren't around back when we organized the Daniel Ballinger Memorial Fund; it was a democratic process where donors were allowed to choose the recipient of the funds, and it also included the emotional part of donating in someone's memory - in this case a stable of our community (Danny Boy had thousands of posts on Tinnitus Talk). Yet we were only able to raise £5,110 - this included A LOT of push we did (including a newsletter to every member). The BTA did also support that campaign.

If we did this, I would like to see - at the very least - the BTA and ATA join the effort and support the campaign.

I thought we might run into a dreadful scenario where we'd have to get their backing. Maybe we should talk more about it on the next call. I still can't post in the PM though.

It sounds like this would better replace OTO-413 but the only red flag for me is that the metabolism of humans is much slower than that of rats.

Yes, this has always been a concern of mine with these lab tests on rats. We have a very similar genetic makeup, but there are still many differences, and what works in rats doesn't always work as well or at all in humans. Also, aren't OTO-413 and the Hough Pill trying to repair the same kind of damage to nerves? So if OTO-413 fails, then perhaps the Hough Pill could accomplish the goal?

Exactly, yes. Intratympanic BDNF vs. NAC+regenerating systemic "nitrate".

This is great news, we have a backup! Do you know if FX-322 has a competitor out there trying to target the same kind of cochlear damage?
Click to expand...
Not any that target the same regenerative mechanisms, not even the one that's mentioned in this podcast. Regain (Audion) kind of works the same way and might be released earlier but could also potentially deplete support cells which drugs like FX-322 would depend on. The IT drug they discussed in this podcast wouldn't appear to be impeded by potential support cell depletion by Regain. I'm not well read on Regain though because I'm not sure if they're going through FDA or EU or both regulatory agencies.

Hmm, so it sounds like it would have to be one or another that a person would receive. So if I understand what I have been reading correctly, the kinds of damage acoustic trauma inflicts is on the OHCs, IHCs, and the synapses. Is there anything else that you are aware of that gets damaged? It seems like the drugs coming out in the near future could be the full package for restoration.

I know I asked @FGG a similar question, I just wanted to get your opinion since you are quite knowledgeable as well.

Spiral ganglion neurons for tinnitus of cochlear origin, but this is unlikely because these are found to be largely in tact even in the profoundly deaf.

Unfortunately a big question mark exists in the role of IHC's and if OHC's are preferentially restored by drugs like Regain and FX-322. But I am confident that tinnitus of cochlear origin will one day be eradicated.

But if enough of the drug is administered and the ceiling is hit for restoring IHCs, won't the only thing left to restore be OHCs? I heard the drug is very safe and can be given in large doses. Thanks.

It's not really clear in what proportion of IHC:OHC drugs like these restore. There are significantly fewer IHC's to restore but that doesn't mean that they will necessarily be "filled up" quicker. Check out the thread on FX-322 in the Research News section, we were actually just discussing this.

and @Liz Windsor for the future transcript.

Liz estimates it's coming before the weekend! She's super fast - we're so glad to have her do these transcripts. It takes MANY hours to create them.

Based on the recent interview it sounds like the pill and injection will only address tinnitus caused by acoustic trauma. Please someone tell me otherwise. Those affected by other than acoustic trauma such as whiplash, ototoxins, etc., are hoping Hough Ear Institute's discoveries will be expanded to help them as well.

Please tell me I am wrong that for now it only addresses acoustic trauma. I want to be wrong. Thank you.

When I first listened to the episode and I heard "49 patreon supporters", I was like "what?"

We're 9 episodes in and only 49 people had at least a dollar to give? As I'm writing this there are 58 patrons, which is better, but we are thousands of people here.

That's nice of you to say, thanks!

This is just how it works, unfortunately. People expect to get content for free, same as most people expect to use this forum for free (I see you're a benefactor though!). And some of our episodes have been listened to over 50,000 times, go figure.

We could generate quite some income from this site and our podcast if we allowed commercial ads, but we don't want to do that, so we are mostly dependent on donations.

@Hazel I also support the podcast on Patreon, but I guess it doesn't appear because I used my other email.

I think the podcast is one of the best ideas for this community.
