NCT06765993

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of isosorbide oral solution compared with placebo in people with unilateral Meniere's disease. A total of approximately 234 subjects will be enrolled in this study: 72 subjects in phase Ⅱ and approximately 162 subjects in phase Ⅲ. Patients were randomly assigned to either the experimental group or the control group. The randomization ratios for phase Ⅱ and phase Ⅲ were 1:1 and 2:1, respectively.

Outcome Measures

Primary Outcomes (1)

  • The changes from baseline in the number of vertigo attacks due to Meniere's disease during the treatment period

    3 months

Secondary Outcomes (7)

  • The changes in the number of vertigo attacks caused by Meniere's disease compared with the baseline at 6 months after the first administration.

    6 months after the first administration

  • The changes in the number of vertigo attacks caused by Meniere's disease compared with the baseline at 4-6 months after the first administration.

    4-6 months after the first administration

  • The changes in hearing from baseline 6 months after the first dose.

    6 months after first dose

  • Patient-reported outcomes (PRO) during the treatment period were assessed using the Dizziness Handicap Inventory (DHI).

    3 months after the first dose

  • Patient-reported outcomes (PRO) during the treatment period were assessed using the Tinnitus Handicap Inventory (THI).

    3 months after the first dose

  • +2 more secondary outcomes

Other Outcomes (8)

  • The incidence and level of adverse events (AEs), serious adverse events (SAEs), abnormal laboratory test indicators, etc.

    From the first dose to 30 days after the last dose

  • Change in tinnitus severity from baseline at 6 months after first dosing.

    6 months after the first dose

  • The change from baseline in the number of attacks due to Meniere's disease at 12 months after the first dose.

    at 12 months after the first administration

  • +5 more other outcomes

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female aged ≥18 and ≤65 years old.
  • Patients with unilateral Meniere's disease who meet the diagnostic criteria for Meniere's disease in the Guidelines for the Diagnosis and Treatment of Meniere's Disease (2017).
  • At least 3 episodes of vertigo caused by Meniere's disease within 6 months before enrollment.
  • Those who understand and voluntarily sign the informed consent.

You may not qualify if:

  • Patients who have had previous ear surgery for Meniere's disease.
  • People who suffer from vertigo caused by organic lesions of the external, middle or inner ear.
  • Patients with diseases that the investigators believe may limit the subjects' participation in this trial:
  • patients with acute intracranial hematoma;
  • patients with hypokalemia (serum potassium \< lower limit of normal) or severe dehydration (needing infusion, or hospitalization, or life-threatening, requiring emergency treatment);
  • patients with acute pulmonary edema;
  • patients with hypotension (systolic blood pressure \<90 mmHg and/or diastolic blood pressure \<60 mmHg during the screening period);
  • patients with severe cardiovascular and cerebrovascular diseases: such as New York Heart Association grade III or IV heart failure, myocardial infarction or unstable angina pectoris within the last 6 months, severe heart failure, progressive multifocal leukoencephalopathy, hypertension that is difficult to control with drugs (systolic blood pressure ≥180 mmHg and/or diastolic blood pressure ≥100 mmHg), etc.;
  • patients with major diseases of other important organs that affect their participation in this study.
  • Patients who need to use diuretics other than trial drugs for a long time after enrollment.
  • Patients with any of the following conditions are known or found in laboratory tests:
  • serum creatinine (Cr) level is not within the normal range;
  • human immunodeficiency virus (HIV) test is positive or has acquired immunodeficiency syndrome (AIDS);
  • active syphilis infection (positive Treponema pallidum antibody and positive non-specific syphilis antibody);
  • active hepatitis, hepatitis B: HBsAg and/or HBcAb are positive and HBV-DNA \> 500 IU/mL or the lower limit of detection of the research center \[only when the lower limit of detection of the research center is higher than 500 IU/mL\]; hepatitis C: HCV antibody is positive and HCV-RNA is positive or greater than the upper limit of normal value.
