Official Title

Phase I Clinical Study on the Safety, Tolerance, Efficacy and Pharmacokinetics of Repeated Intratympanic HY01 in Patients With Sudden Sensorineural Hearing Loss

Brief Summary

      Phase I clinical study on the safety, tolerance, efficacy and pharmacokinetics of repeated
      intratympanic HY01 in patients with sudden sensorineural hearing loss. In this study,
      low-dose group and high-dose group were designed, 6 cases in each group.

Detailed Description

      The incidence rate of sudden deafness is increasing year by year, which can cause severe
      hearing loss. Intratympanic HY01 can increase the local drug concentration in the ear, which
      is equal to or better than that in the treatment of sudden sensorineural hearing loss, and
      reduce the systemic drug concentration at the same time. It has obvious clinical value for
      the treatment of hormone forbidden population.

      HY01 is one of glucocorticoid drugs. In this study, we designed low-dose group and high-dose
      group of HY01, and enrolled 6 patients with sudden sensorineural hearing loss for salvage
      therapy in each group. HY01 will be administrated on D1, D4 and D7 . The trial will be ended
      30 days after the first administration.

      After determining the safety of low-dose, the patients in the high-dose group will be
      enrolled. The safety observation indexes included systemic Routine Indexes and otology
      indexes, and the efficacy and pharmacokinetics were observed at the same time.
