About this study

Official title: Evaluation of Safety and Pharmacokinetic Profiles of a Single-dose HHT201 in Healthy Subjects

The objective of this study is to evaluate the safety and pharmacokinetic profiles of HHT201 in healthy subjects.

Read the detailed description

The study aims to evaluate the safety, pharmacokinetics and to determine the potential dose limiting toxicity of HHT201 in healthy subjects between the ages of 20-59, 6 in 17mg dose group and 20 in 34mg dose group. Another 12 subjects will be administered a tablet of 5mg Donepezil Hydrochloride to get the PK profile of Donepezil as reference. Eligible subjects will be accepted into the protocol after review and providing voluntary written informed consent forms and completion of a comprehensive medical, physical examination, and routine laboratory assessment.

Conditions
AD
Being tested
Donepezil Pamoate for Injection 17mg, Donepezil Pamoate for Injection 34mg, Donepezil Hydrochloride 5mg

What participants receive

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

  • Donepezil Pamoate for Injection 17mgDrug

    Also called HHT201

    A dosage of 17mg HHT201 will be injected into the muscle in the gluteus once.

  • Donepezil Pamoate for Injection 34mgDrug

    Also called HHT201

    A dosage of 34mg HHT201 will be injected into the muscle in the gluteus once.

  • Donepezil Hydrochloride 5mgDrug

    Also called Aricept

    A tablet of 5mg Donepezil Hydrochloride will be administered once.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cmax of Donepezil

    Maximum observed concentration of drug substance in plasma.

    Measured: Blood samples collected over a 35 days period

  2. Tmax of Donepezil

    Time when the maximum concentration is acheived

    Measured: Blood samples collected over a 35 days period

  3. AUClast of Donepezil

    Area under the concentration-time curve from time zero to time of last measurable concentration.

    Measured: Blood samples collected over a 35 days period

  4. AUC0-∞ of Donepezil

    Area under the concentration-time curve from time zero to infinity.

    Measured: Blood samples collected over a 35 days period

  5. t1/2 of Donepezil

    The time when the concentraion of the drug eliminated to half of the initial.

    Measured: Blood samples collected over a 35 days period

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Donepezil Pamoate for Injection 17mg, Donepezil Pamoate for Injection 34mg and Donepezil Hydrochloride 5mg in people with AD, run by Shanghai Synergy Pharmaceutical Sciences Co., Ltd. at 1 site 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 4 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 29 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Cmax of Donepezil (time frame: Blood samples collected over a 35 days period). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Sep 2020.
