About this study

Official title: A Safety and Tolerability Evaluation of Ascending Single Oral Doses of Metacavir Enteric-coated Capsules Using a Randomized,Double-blind, Placebo-controlled Design Conducted in Chinese Healthy Adult Volunteers

A Safety and Tolerability Evaluation of Ascending Single Oral Doses of Metacavir Enteric-coated Capsules Using a Randomized,Double-blind, Placebo-controlled Design conducted in Chinese Healthy Adult Volunteers.

Read the detailed description

A study to evaluate the safety and tolerability of ascending single oral doses of metacavir enteric-coated capsules using a placebo-controlled design conducted in Chinese healthy adult volunteers, and to provide references for the clinical trial of the next phase Ⅰ and Ⅱ.

48 eligible healthy subjects are involved. According to the set ascending-doses groups, subjects will be randomized in a 3:1 proportion to orally take a single dose of Metacavir enteric-coated capsule or placebo on the condition of fasting. Each group has 8 people, evenly composed of men and women. The beginning dose of the study is 40mg/d.According to the dose escalation method, subjects who have successfully completed tests of the previous dose group and passed the safety assessment will enter the next dose group with the same method. All subjects check in the phaseⅠresearch center one day early before taking the test drug. Vital signs and ECG will be observed before and 0.5,1,2,4,8,12,18,24,48,72 hours after administration and at the follow-up day which is the 7th day since administration. Laboratory tests will be conducted before and 6,24,48,72 hours after administration and at the follow-up day , and the adverse drug events are observed throughout the test.

Being tested
PNA 40mg, PNA 80mg, PNA 160mg, PNA 240mg, PNA 360mg

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PNA 40mg, PNA 80mg and PNA 160mg in people with Chronic Hepatitis B, run by Guangzhou Yipinhong Pharmaceutical 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 5 inclusion and 17 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 2 Jun 2017. 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. 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 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?

Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] (time frame: Baseline, up to Day 7). 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 2 Jun 2017.
