AC102: The Potential Game-Changer for Sudden Hearing Loss
Well, well, well! Hold onto your hearing aids, folks—MedUni Vienna has just stirred the pot with some exciting research on a new compound called AC102. You know, because nothing says love like a little bit of science in your life! If you’re wondering why this is such a big deal, let me break it down for you.
A research team led by MedUni Vienna has investigated AC102, a new active substance that offers hope of an effective treatment for acute sudden hearing loss. The latest results have been published in the scientific journal “Cell Death & Disease“. Initial findings from preclinical trials could represent a significant advancement in the treatment of acute hearing disorders.
The effectiveness of AC102 was demonstrated in a study led by Christoph Arnoldner (Department of Otorhinolaryngology at MedUni Vienna) and Hans Rommelspacher (Audio Cure Pharma GmbH, Berlin) using animal models with cochlear implants. Cochlear implantation is currently the only treatment option for advanced hearing loss in order to partially restore the hearing ability. The preservation of residual hearing is of crucial importance, as the remaining “natural” hearing in combination with the electrical stimulation of the implant improves speech comprehension and general hearing perception. However, the surgical procedure can damage the inner ear and lead to the loss of residual hearing. Until now, there has been no effective method to prevent or treat this loss. “In our study, we have now been able to show that the residual hearing of animals that were administered AC102 once increasingly recovered in contrast to untreated animals,” reports first author Michael Nieratschker (Department of Otorhinolaryngology at MedUni Vienna). With the help of cell cultures and inner ear models, the study also found an explanation for this effect: AC102 has an anti-inflammatory effect and thus protects the hair cells and auditory nerves from dying.
The Treatment of Sudden Hearing Loss in Sight
The results of the study allow the conclusion that AC102 could also be effective in acute sudden hearing loss. “Sudden hearing loss is usually treated with cortisone, but recent studies show that this approach often does not work,” emphasises Christoph Arnoldner, Head of the CD Laboratory for Inner Ear Research at MedUni Vienna. “Since inflammatory processes and cell damage also play a role in acute sudden hearing loss, as in the case of residual hearing loss in cochlear implantation, the use of AC102 was also investigated in this context,” explains Michael Nieratschker. The efficacy of the substance has already been demonstrated in a preclinical study involving MedUni Vienna. A Phase I study to confirm the safe use of AC102 at MedUni Vienna and Radboud University in Nijmegen (Netherlands) has also already been successfully completed. The Phase II study to confirm efficacy in patients is being conducted at several European centres, including MedUni Vienna’s Department of Otorhinolaryngology. “All the results so far give us reason to hope that AC102 could be suitable for the treatment of acute sudden hearing loss,” say Christoph Arnoldner and Michael Nieratschker optimistically.

So, what’s the takeaway? AC102 could become the superhero we didn’t know we needed in the fight against hearing loss! And if you’re on the edge of your seat, don’t worry—the researchers are charging forward with a clinical trial. Who knew science could be this thrilling? It’s like a cliffhanger, but with fewer explosions and more… eardrums.
Now, let’s just hope when this mystical AC102 arrives at our local pharmacy, it doesn’t come with the side effects of turning us all into hearing-impaired superheroes—but hey, I wouldn’t mind a cape! 👂🦸♂️
A research team from MedUni Vienna has made significant strides in the field of otorhinolaryngology by investigating AC102, a groundbreaking active substance that shows promise as a potential treatment for acute sudden hearing loss. The team’s latest findings, now published in the esteemed scientific journal “Cell Death & Disease“, suggest that AC102 could be pivotal in the evolution of therapies targeting acute auditory disorders. Initial results from extensive preclinical trials indicate a remarkable advancement in the treatment methodologies for individuals suffering from hearing impairments.
The study, spearheaded by Christoph Arnoldner of the Department of Otorhinolaryngology at MedUni Vienna alongside Hans Rommelspacher from Audio Cure Pharma in Berlin, showcased AC102’s effectiveness using advanced animal models equipped with cochlear implants. Cochlear implantation currently stands as the sole option for addressing profound hearing loss, aiming to partially revive auditory perception. It’s essential to maintain residual hearing, as this unaltered auditory capacity combined with electrical stimulation from implants significantly enhances both speech comprehension and overall auditory experiences. Nevertheless, the surgical process poses risks of inner ear damage, potentially compromising residual hearing. Michael Nieratschker, the study’s first author, noted, “In our study, we have observations indicating that animals treated with AC102 demonstrated improved restoration of residual hearing when compared to their untreated counterparts.” Through the utilization of cell cultures and inner ear models, the research discovered that AC102 exhibits anti-inflammatory properties, safeguarding both hair cells and auditory nerves from degeneration.

The conclusive results of this study imply that AC102 may also be effective for treating acute sudden hearing loss. Christoph Arnoldner, the leading authority of the CD Laboratory for Inner Ear Research, pointed out, “Currently, sudden hearing loss is typically managed with cortisone; however, emerging studies indicate that this method frequently falls short.” Michael Nieratschker elaborates, “As both inflammatory responses and cellular damage are significant factors in acute sudden hearing loss, much like with residual hearing loss in cochlear implant procedures, we sought to evaluate the potential of AC102 in this situation.” The efficacy of AC102 has previously been validated in a separate preclinical study conducted by MedUni Vienna. Moreover, a successful Phase I study to ensure the substance’s safe application has been completed in collaboration with Radboud University in Nijmegen, Netherlands. Currently, a Phase II study aimed at confirming its effectiveness in human patients is actively underway at several European medical centers, including the esteemed Department of Otorhinolaryngology at MedUni Vienna. With encouraging results thus far, Christoph Arnoldner and Michael Nieratschker share an optimistic outlook, stating, “All indications so far lead us to believe that AC102 has great potential in treating acute sudden hearing loss.”
