About this study

Official title: RCT Study of Liuwei Dihuang Pill Preventing and Treating Presbycusis With Shen (Kidney)-Yin Deficiency

The objective of this study is to examine the effects and safety of Liuwei Dihuang pill and placebo in presbycusis with Shen (kidney)-yin deficiency.

Read the detailed description

There are no approved pharmacologic therapies for age-related hearing loss (ARHL), also known as presbycusis. Based on the syndrome differentiation in Chinese medicine (CM) theory, the pathogenesis of presbycusis is related to the Shen (kidney)-yin deficiency. Liuwei Dihuang Pill (LDP) is effective and commonly prescribed for the treatment of Shen-yin deficiency.

The main purpose of this study is to try to demonstrate an improvement in phonetically balanced maximum (PBmax) after 1 years of treatment with the LDP versus the placebo. Subjects will undergo a safety follow-up after the treatment period. Safety and efficacy will be determined by looking at a number of assessments (physical examinations, blood sampling, hearing assessments, questionnaires, etc.).The amount of drug in the blood will also be measured.

It is expected that around 120 people (at least 60 in each arm) with presbycusis with Shen (kidney)-yin deficiency may take part in the study. The study participants will be recruited at around 6 sites in the Shanghai, China.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Liuwei Dihuang Pill (marketed product in China)Drug

    Also called Liu Wei Di Huang Pill

    LDP group and placebo group were used for treatment. The random number is generated by the central randomization system. All the recruiters were divided into placebo group and LDP group. The numbers will be assigned according to random numbers. In this study, qualified subjects were randomly assigned to the LDP group and placebo group at a ratio of 1:1. The drug was administered for 48 weeks, 3 times a day, 8 pills each time.

  • Liuwei Dihuang Pill(placebo )Drug

    Also called placebo group

    LDP group and placebo group were used for treatment. The random number is generated by the central randomization system. All the recruiters were divided into placebo group and LDP group. The numbers will be assigned according to random numbers. In this study, qualified subjects were randomly assigned to the LDP group and placebo group at a ratio of 1:1.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Liuwei Dihuang Pill (marketed product in China) in people with Presbycusis and Age-related Hearing Loss, run by Shanghai Jiao Tong University School of Medicine at 6 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in PB-Max after 48 weeks of treatment (time frame: 48 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05125081, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2026.
