About this study
Official title: A Phase 1/2a, First-in-human, Open-label, Dose-escalating Study With a Safety Expansion Cohort to Evaluate Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Anti-tumour Activity of TAX2 in Patients With Relapsed/Refractory Advanced/Metastatic Solid Tumours
The purpose of this clinical trial is to investigate the treatment for adult patients suffering from advanced or metastatic solid tumours and has 2 parts to the study: the Phase 1 where ascending doses of the experimental study drug, TAX2, will be tested and the Phase 2a where all the participants will receive the study drug at the same dose considered as the recommended Phase 2 dose from Phase 1 part. The participation in the Phase 1 or in the Phase 2a part depends on when the participant is proposed to join the study.
The study purpose is to assess:
- How safe and tolerable TAX2 is. This assessment will be based on the adverse effects collected during the study.
- How well TAX2 enters the body, circulates in the body, and leaves the body (known as pharmacokinetics, PK) by measuring the level of the drug in the blood
- What the drug does with the body and the tumour (known as pharmacodynamics, PD)
- The effect TAX2 has on the tumours (anti-tumour activity)
- Also define the Dose Limiting Toxicity (DLT) and the recommended Phase 2 Dose (RP2D)
- Conditions
- Solid Tumor Cancers
- Being tested
- TAX2
What participants receive

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing TAX2 in people with Solid Tumor Cancers, run by Apmonia Therapeutics at 4 sites in 2 countries.
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 15 inclusion and 33 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: opening soon, as of the sponsor's last update on 7 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Belgium, France. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Number of patients with DLTs _ Phase 1 (time frame: From enrollment to the end of Cycle 1 (each cycle is 28 days)). 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 7 Jul 2026; AzTrials last refreshed its copy on 31 Oct 2026.
