About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Phase I Clinical Study to Evaluate the Safety, Tolerability, and Pharmacokinetic Characteristics of HH-1270 Tablets in Healthy Chinese Participants

This study is a single-center, randomized, double-blind, placebo-controlled, single ascending dose (SAD) and multiple ascending dose (MAD) clinical trial to evaluate the safety and PK profile in healthy Chinese subjects.

Read the detailed description

SAD consists of 6 prespecified dose levels. Participants are enrolled in cohorts according to the dose-escalation principle and randomized to receive HH-1270 tablets (A) or placebo (P). Higher dose cohorts may begin only after confirmation by the SRC for the lower dose cohort. This part aims to evaluate the safety, tolerability, PK, and PD characteristics of single-dose HH-1270. One dose cohort in the SAD phase will be selected for a food-effect exploration.

MAD consists of 4 prespecified dose levels. Each participant receives once-daily dosing under fasting conditions for 7 consecutive days and is randomized to receive HH-1270 tablets (A) or placebo (P). Higher dose cohorts may begin only after confirmation by the SRC for the lower dose cohort. This part aims to evaluate the safety, tolerability, PK, and PD characteristics of multiple-dose HH-1270.

Being tested
HH-1270, placebo

What participants receive

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HH-1270 in people with Chronic HDV Infection, run by Huahui Health 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 15 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: opening soon, as of the sponsor's last update on 15 Oct 2026. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Xiyu Zhang (18701650516, zhangxiyu@hhhbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of adverse events (AEs) and serious adverse events (SAEs) (time frame: up to 15/21 days in SAD/MAD). The study lists 2 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 15 Oct 2026.
