About this study

Official title: Randomized, Double-blind, Double-mal Injection, Control Study of Phase II Clinical Dose Calibration of BCG Pure Protein Derivative (BCG-PPD)

This phase II clinical trial used randomized, double-blind, double-arm intradermal injection, and the same marketed products, selected 30 pulmonary tuberculosis patients aged 18-65 years who met the inclusion criteria and did not meet the exclusion criteria, and conducted the double-arm skin test using BCG-PPD and marketed BCG-PPD controls.

During the screening period, the subjects underwent evidence collection of confirmed tuberculosis, physical examination, vital signs, blood routine, urine routine, blood biochemistry, electrocardiogram, chest CT, HIV antibody test, and blood pregnancy examination of women of childbearing age; Vital signs examination before the skin test, The injection site was photographed 0min after the skin test, Vital signs were performed 30min after the skin test; Vital signs were examined, pictures of the injection site was taken, and the injection site reaction was measured; Observe the skin test response, Record the redness, hardening longitudinal diameter and transverse diameter and other related reactions; All adverse events within 72h after the skin test were recorded and safety evaluated.

Read the detailed description

Prior to the commencement of the study, the Investigator/his authorized officer will contact the subject and/or guardian to enroll the candidate subjects and invite them to participate in the study.Subjects who are eligible for screening receive the drug number in the order they arrive at the random number allocation room.During the screening period, tuberculosis diagnosis evidence collection, physical examination, vital signs, blood routine, urine routine test, blood biochemistry, electrocardiogram, chest CT, HIV antibody test and blood pregnancy examination of women of childbearing age were conducted; after screening, study number (drug number) was assigned, and double arm BCG-PPD skin test with 0.1ml injection. Vital signs should be taken before skin test, injection site photographed 0min and 30min after skin test; vital signs examined, injection site photographed and measured 48-72h after skin test; observe skin test reaction, record red, hard vertical diameter and transverse diameter and other related reactions of skin test; record all adverse events within 72h after skin test and perform safety evaluation.

What is being measured

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

  1. Injection-site reaction endpoint

    Evaluate the occurrence of positive reactions,like the transverse and longitudinal diameter of skin redness, induration, and strong positive reactions in 24 hours necrosis, and lymphangitis between 24 hours and 72 hours after the skin test

    Measured: Within 24 hours and 48 hours to 72 hours after the skin test

  2. Safety endpoint

    The incidence of all adverse events (AES) within 72 hours after drug injection in the subjects;

    Measured: Within 72 hours after the skin test

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Purified Protein Derivative of BCG(BCG-PPD) in people with Tuberculosis, run by Anhui Zhifei Longcom Biologic Pharmacy 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 8 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 16 May 2025. 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?

Injection-site reaction endpoint (time frame: Within 24 hours and 48 hours to 72 hours after the skin test). 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 16 May 2025.
