About this study

Official title: A Randomized, Double-blind, Placebo-controlled Phase Ib/II Study to Evaluate the Efficacy and Safety of HB0056 in Adult Participants With Moderate to Severe Asthma

The goal of this clinical trial is to learn if drug HB0056 works to treat severe asthma in adults. It will also learn about the safety of drugHB0056. The main questions it aims to answer are:

Does drug HB0056 lower the number of times participants need to use a rescue inhaler? What medical problems do participants have when taking drug HB0056? Researchers will compare drug HB0056 to a placebo to see if drug HB0056 works to treat severe asthma.

Participants will:

Take drug HB0056 or a placebo Q2W. Keep a diary of their symptoms and the number of times they use a rescue inhaler

Read the detailed description

Eligible subjects enrolled in this study must meet the following criteria: male or female subjects aged 18-75 years with moderate to severe asthma; weighing ≥ 40 kg with a body mass index between 18-40 kg/m2; having been diagnosed with chronic asthma for at least 1 year prior to screening; receiving moderate- to high-dose inhaled corticosteroids (ICS) for at least 3 months prior to screening; used at least one other asthma control drug, such as LABA, LTRA, etc., which have been stable for at least 1 month prior to screening.

This study consists of 2 parts. Part I is a phase Ib, randomized, double-blind, placebo-controlled, parallel-group, multiple dose-escalation study which is designed to determine the safety, PK, immunogenicity, and preliminary clinical efficacy of multiple doses of HB0056 Injection in subjects with moderate or severe asthma. Part II is a phase II clinical study aimed at exploring the efficacy and safety of different dosing regimens of HB0056 for the treatment of moderate to severe asthma, and recommending the optimal treatment regimen for the phase III clinical study.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing HB0056 in people with Asthma, run by Shanghai Huaota Biopharmaceutical Co., Ltd. at 2 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 9 inclusion and 11 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: looking for participants now, as of the sponsor's last update on 28 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 2 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 combined 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.

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?

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 Jingjing Wang (86-21-5132 0051, jingjing.wang@huaota.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part I(Phase Ib): AEs (time frame: From baseline to week 16). The study lists 3 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 28 Oct 2026.
