Filter by:This is a Phase 2, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter study to evaluate the efficacy of FX-322, administered by intratympanic injection, in adults with acquired sensorineural hearing loss (SNHL).
Each year, military epidemiological surveillance counts approximately 1,000 acute acoustic injuries. Most are caused by exposure to weapon noise during training sessions while military personnel are provided with hearing protection. Several hypotheses could explain the occurrence of acute acoustic trauma despite wearing protections: - A lack of practices or knowledge about the use of hearing protection equipment that could facilitate the occurrence of acute acoustic trauma (improper fitting, use of an inappropriate type of protection, dropping of protectors, inappropriate removal) - A failure to seal the external ear canal due to an inappropriate plug size. These hypotheses will be explored using a questionnaire distributed to a population of Army soldiers training to shoot. The main objective is to determine the predictive factors corresponding to practices or knowledge related to the use of hearing protection equipment in the occurrence of acute acoustic trauma in a population of Army soldiers.
This is a Phase 1b, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter, safety study of FX-322, administered by intratympanic injection, in adults with severe sensorineural hearing loss.
This is a Phase 1b, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter, safety study of FX-322, administered by intratympanic injection, in adults with age-related sensorineural hearing loss.
This is a phase 2a single and repeat dose exploratory efficacy study of intratympanic FX-322 compared to placebo in healthy male and female adults with stable sensorineural hearing loss.
This research project will contribute to the research surrounding the effect on the ear after noise exposure. This ever-growing field of research has never been more applicable than now with the increase of recreational noise exposure. Noise is the leading cause of preventable hearing loss and excessive occupational noise along with recreational noise exposure can cause a devastating disability. The World Health Organisation (WHO) estimates 1.1 billion young people could be at risk of hearing loss due to unsafe listening practices. One of the mechanisms that could increase the resistance against noise induced hearing loss is 'sound conditioning'. Animal studies have found that prior exposure to low level noise over a period of a few weeks can 'condition' the ear. This conditioning then reduces the susceptibility to high level exposure i.e. strengthening the ear. In this study, the investigators aim to determine whether previous exposure to loud noise can condition the human ear, reducing the temporary hearing loss and temporary tinnitus ("ringing in the ear") that sometimes occurs after attending a loud nightclub or live music event. There are many implications of this research. For one it will allow us to understand more about the susceptibility to exposure of sounds and the resistance against noise induced hearing loss. This will mean that the investigators can enable appropriate interventions if necessary. For example, individuals who are more susceptible due to low prior exposure may be advised that they are at risk, and encouraged to use hearing protection. Being able to learn more about the impacts of noise with hearing and educate others such as understanding the impacts from high-level exposure.
The primary objective of this work is to determine the effect noise has on the auditory system (both auditory health and performance) and also the degree to which the effect of pre-noise therapy such as Near Infrared (NIR) light can mitigate the effects of noise exposure.
Twenty patients with tinnitus and a typical noise-induced hearing loss (NIHL) audiogram were included. Each subject underwent an otoscopic examination, distortion product otoacoustic emissions, tinnitus-match testing, Tinnitus Handicap Inventory (THI) and serum zinc level analyses. After 2 months of treatment with zinc, all tests were repeated.
Farm and rural youth have frequent exposure to hazardous noise on the farm and recreationally, and have an increased prevalence of noise-induced hearing loss (NIHL). There is a lack of programs to prepare this high-risk population to use hearing conservation strategies. This randomly-controlled trial of innovative community-based interventions is designed to compare effectiveness and sustainability of approaches to increase youths' use of hearing conservation strategies. Consistent use of hearing conservation strategies is expected to reduce rates of NIHL and other negative effects of high noise exposure, and improve quality of life in this high-risk and underserved group.
This study is a single-center, randomized, placebo-controlled, double-blind, single ascending dose escalation study to determine the safety, tolerability, and PK profile of oral administration of HPN-07 in single doses to approximately 32 healthy male and female subjects between 18 and 55 years of age. Subjects will receive single oral doses of the study drug. The primary endpoint of this trial is to establish the safety and tolerability of HPN-07 and HPN-07 plus N-acetylcysteine (NAC).
