HER2-positive biliary cancer
HER2 biliary cancer trial Australia: Early-phase now recruiting
Most patients miss trials like this, not because they don’t qualify, but because they don’t know what to look for in time.
When you’re dealing with cholangiocarcinoma, everything is moving fast, and it’s not always clear what matters.
This trial only applies if your tumour is HER2-positive. If that hasn’t been identified, this option is easily missed.
If you know your HER2 status early, this becomes a real option. If you don’t, it’s missed entirely.
Steve HolmesOutline
This trial includes multiple cancer types. Biliary cancer is one subgroup being studied.
If you have confirmed HER2-positive disease and have already received at least one line of treatment, this may be an option to explore with your treating team.
Trial reference: NCT05523947
What this is
Biology
This trial targets HER2, a growth signal (A receptor protein) present on the cell’s surface in a minority of biliary cancers.
Physiology
The study drug (YH32367) is designed to block this signal and disrupt tumour growth.
Cognition (understanding)
This is a first-in-human Phase 1 and 2 trial.
Its primary purpose is to assess safety and dosing, with early signals of tumour response.
It also studies how the drug is processed in the body.
This is not a proven treatment.
How This Works
Biology (engine parts)
These are the key components the drug depends on:
HER2 expression level
How much HER2 is present on the cancer cell.
This is the key filter. High levels make this trial relevant.
HER2 receptor
The signal receiver on the cell surface that the drug attaches to.
Cell surface (membrane)
Where HER2 sits and where the drug must bind.
Growth signalling
The internal message that drives tumour growth when HER2 is active.
The Physiology (The engine in flow)
The Physiology of this drug:
YH32367 is a laboratory-made antibody protein given by infusion.
It is a real protein, similar to antibodies your body naturally makes, but designed to recognise a specific target. Antibodies are proteins your immune system uses to find and attach to things it needs to control or remove.
It is designed to find and attach to HER2, a protein receptor on the surface of some cells that receives growth signals.
In some tumours, HER2 is overexpressed. This means the cell receives too many growth signals, which can drive rapid growth.
By attaching to HER2, the drug blocks or interferes with these signals and may help slow tumour growth.
Who this is for
Patients must meet all of the following:
- Confirmed HER2-positive biliary tract cancer
- At least one measurable tumour on CT or MRI
- Have received at least one prior line of therapy
- Willing to undergo monitoring and possibly a biopsy
If you are unsure of your HER2 status, check your pathology report or speak with your oncologist.

Why this matters
For the right patient, this opens another pathway, but only if it’s recognised in time.
This trial depends on one thing: your HER2 status.
If that hasn’t been identified, this option is easily missed.
This is where most patients lose options, not because they don’t exist, but because they aren’t seen early enough.
This is an early-phase trial. That means the window to be considered matters.
Its purpose is safety and dosing, not guaranteed benefit.
What participation involves
Patients in this study will:
- Receive the investigational treatment
- Attend regular medical assessments
- Undergo blood tests and imaging such as CT scans
- Possibly provide tumour tissue for analysis
This trial does not replace standard medical care. Participation is voluntary, and patients can withdraw at any time.
The risk is not the trial. The risk is missing it.
This is how options are kept open, by identifying what matters early and acting on it.
Start here
- Check your pathology report for HER2 status
- If it is not listed, ask your oncologist directly
- If HER2-positive, review this trial with your team immediately

Final position
This is a specific, early-stage trial for a defined biological subgroup.
It is not a general treatment pathway.
Used correctly, it helps the right patient explore an additional option.
Why We Are Here
Cancer becomes the way, not because we want it to, but because it leaves no alternative.
When cancer stands in the way, it becomes the way.
The question is not whether the obstacle of cancer exists.
It is whether we will use it to find a new way forward.
Clinical Trials provide new ways.

We are a patient-led community, built on a culture that functions as a survival system in itself.
Cholangiocarcinoma is not just a disease. It is the obstacle you must respond to.
What you do next determines the path.
That response becomes the way.
That is on you. Now.
Patient Response System
Journal. App. AI.
Patients shouldn’t be deprived of survival knowledge.
Most patients lose options not because of the cancer alone,
but because understanding comes too late.
We built the pathway to turn understanding into early action so that options won’t be lost.
