About this study

Official title: A Phase 1a Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Immunogenicity of PD5K3 in Healthy Adult Volunteers

The main aim of this clinical trial is to assess the safety of PD5K3 in patients aged 18 to 65 years. The main questions it aims to answer are:

  • Is PD5K3 safe in adult? Researchers will compare PD5K3 to an active comparator pegaspargase to see if PD5K3 is safe and active in human.

Participants will

  • Receive a single dose injection of PD5K3, pegaspargase or placebo according to weight,
  • Visit the clinic for assessment.
Read the detailed description

This study is a first-in-human study, which is a single-center, randomized, placebo-controlled, double-blind, dose escalation, clinical study, aiming to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of PD5K3 in healthy adult volunteers, compared with pegaspargase at the same dose.

Being tested
PD5K3, Placebo, Pegaspargase
Medical subject headings
Precursor Cell Lymphoblastic Leukemia-Lymphoma

  • PegaspargaseDrug

    Also called Aiyang®

    Six dose levels will be evaluated. intramuscular injection

Study groupRoleWhat they receive
PD5K3 groupExperimentalEight subjects will be randomized to receive a single dose of PD5K3 in a double-blind fashion at each dose level.
Receives: Drug: PD5K3
PD5K3 Placebo groupPlacebo comparatorTwo subjects will be randomized to receive placebo in a double-blind fashion at each dose level.
Receives: Drug: Placebo
Pegaspargase groupActive comparatorFour subjects will receive a single dose of pegaspargase at the each dose level, and the dose of pegaspargase is the same with PD5K3. This group is open-labelled.
Receives: Drug: Pegaspargase

What is being measured

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

  1. Treatment-related Adverse Events

    To evaluate the adverse events as characterized by type, frequency, severity as graded by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, timing, seriousness, and relationship to study therapy after administration.

    Measured: up to 49 days

Secondary outcomes (5)
  1. The Area Under the Curve from dosing to the time of the last measured concentration (AUC0-t)

    Pharmacokinetic parameter

    Measured: up to 49 days

  2. Maximum plasma concentration (Cmax)

    Pharmacokinetic parameter

    Measured: up to 49 days

  3. The half-life (t1/2)

    Pharmacokinetic parameter

    Measured: up to 49 days

  4. Compare the plasma asparaginase activity between the PD5K3 and pegaspargase groups

    Plasma asparaginase activities are determined by a validated enzymatic spectrophotometric assay, and the results are reported in IU/mL. In the assay, asparaginase hydrolyzes asparagine to generate aspartic acid, which can be detected colorimetrically using a coupled enzymatic reaction.

    Measured: up to 49 days

  5. Compare the plasma asparagine concentration between the PD5K3 and pegaspargase groups

    Plasma asparagine concentration as a pharmacodynamic parameter

    Measured: up to 49 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PD5K3 and Pegaspargase in people with Lymphoblastic Leukemia, Acute and Lymphoblastic Lymphoma, run by Chongqing Peg-Bio Biopharm 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 19 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 30 Jul 2024. 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?

Treatment-related Adverse Events (time frame: up to 49 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 30 Jul 2024.
