What is being measured

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

  1. Incidence and Nature of Adverse Events (AEs)

    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered to be related to the study treatment.

    Measured: From the time the ICF is signed until 30 days after last dose of study treatment

  2. Arm A and B only: Incidence and nature of dose-limiting toxicities (DLTs) during the first cycle of treatment

    DLTs will be assessed during the safety run-in phase and are defined as toxicities that meet pre-defined severity criteria and assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, intercurrent illness, or concomitant medications that occurs within the first cycle (4 weeks for Arm A, 3 weeks for Arm B) of treatment

    Measured: Arm A: During the first four weeks of study treatment Arm B: During the first three weeks of study treatment

  3. Objective Response Rate (ORR) by RECIST V1.1

    The ORR is defined as the proportion of subjects with confirmed CR or confirmed PR, based on RECIST Version 1.1

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HMBD-001, Docetaxel and Nab-paclitaxel in people with Non-Small Cell Lung Cancer and Pancreatic Cancer, run by Hummingbird Bioscience at 5 sites in Australia.

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 13 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: under way, not looking for participants, as of the sponsor's last update on 18 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Australia. 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?

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?

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?

Incidence and Nature of Adverse Events (AEs) (time frame: From the time the ICF is signed until 30 days after last dose of study treatment). 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?

On the ClinicalTrials.gov record for NCT05919537.

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 18 Apr 2025.
