About this study

Official title: A Phase I, Open-Label, Multi-Dose Study for Evaluation of the Safety, Pharmacokinetics, and Antiviral Activity of UB-421 Subcutaneous Formulation Administered in HIV-1 Infected Treatment Naive Patients

This is a phase I, open-label, dose-escalation study to investigate short-term safety, pharmacokinetics, and antiviral activity of UB-421 SC with 4 weekly doses in treatment naive HIV-1 infected patients. Eligible (n=6 per dose cohort) subjects will be sequentially enrolled into 3 escalating-dose cohorts to receive 4 weekly fixed doses of UB-421 SC at either 250 mg (Cohort A), 500 mg (Cohort B) or 700 mg (Cohort C). Subjects should be followed for safety for additional 4 weeks after the last UB-421 SC dosing. In order to control viral load while minimizing confounding in safety assessment, subjects can initiate standard anti-retroviral therapy (ART) two weeks after the last UB-421 SC dosing.

Escalation to the next higher dose cohort will be determined based on dose limited toxicity (DLT) evaluation. The dose escalation will be stopped if ≥ 2/6 subjects experience DLT or when clinical trial steering committee (CTSC) determines it is not suitable to escalate the dose level.

In this study, DLT is defined as any ≥ grade 3 AE occurred within 21 days from prior UB-421 SC dosing and is considered drug related.

When there is any ≥grade 3 AE(s) occurred within 21 days from prior UB-421 SC dosing in any subject out of the current dose cohort (n=6), the duty of the CTSC will be initiated. The CTSC will be responsible for DLT evaluation. The committee members will evaluate the safety data of all subjects in each cohort through baseline to at least 21 days following the last UB-421 SC dosing. The administration of the next higher dose level at TV1 will be conducted after the committee grants the dose escalation. However, dose escalation will be proceeded if there is no ≥ grade 3 AE and upon agreement from all investigators without holding the steering committee meeting.

Subjects will be assessed at Screening, weekly during Treatment Period and Follow-up Period. The assessment includes physical examination, vital sign, laboratory parameters, HIV-1 viral load, CD4+ and CD8+ T-cell counts. Samples for the drug concentration measurement will be collected at weekly intervals throughout the study, immediately before UB-421 SC dosing. Additional intensive PK sampling will be scheduled during the first dosing interval (from TV1 to TV2) at 1, 3, 6, 24, 48, 72 and 96 hours post first UB-421 SC dosing for PK subgroup (at least 3 subjects per dose cohort). The immunogenicity of UB-421 SC will be monitored by measuring anti-UB-421 antibodies in pre-dose serum samples at day 0 and post-dose serum at day 14, 28, 35, 42 and 49. Viral reservoir, immunophenotyping and CD4+ (D1) receptor occupancy will also be explored.

Subjects should discontinue from UB-421 SC treatment if they experience a sustained decrease from baseline in CD4+ (D2) T cell counts of ≧50% at two consecutive visits or drug-related AE(s) with severity grade 3 or 4 (according to the Division of AIDS, National Institute of Allergy and Infectious Diseases (DAIDS) AE grading).

What is being measured

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

  1. Numbers and incidence of TEAEs

    Numbers and incidence of TEAEs that are ≥ Grade 2 and study treatment related, TEAEs (any grades) by maximum severity, TEAEs by relationship to study treatment, SAEs, TEAEs leading to death, and TEAEs leading to discontinuation of study treatment will be tabulated by dose cohort and will be summarized by system organ class and preferred term for study period (Treatment or Follow-up). The "Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events" will be used in this study for all AE severity grading, except skin abnormalities, which will be evaluated according to Common Terminology Criteria for Adverse Events (CTCAE).

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing UB-421 SC(dB4C7C22-6 mAb) in people with HIV-1 Infection, run by United BioPharma at 1 site in Taiwan.

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 11 inclusion and 21 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 24 Apr 2023. 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 Taiwan. 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?

Numbers and incidence of TEAEs (time frame: 28 days). 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 24 Apr 2023.
