About this study

Official title: A Phase 1, Open Label, Dose-Escalation and Expansion Study to Evaluate Safety, Pharmacokinetics and Initial Therapeutic Activity of AVA6103, a Novel FAP-activated Exatecan Administered Intravenously in Subjects With Locally Advanced or Metastatic Selected Solid Tumors

This is a first-in-human (FIH), Phase 1 open-label, multicenter dose escalation study investigating AVA6103 monotherapy administered intravenously in patients with locally advanced (unresectable) or metastatic solid tumors that are likely to be FAP positive. The study consists of an initial Phase 1a dose escalation portion and a subsequent Phase 1b dose expansion portion upon completion of the dose escalation portion.

Read the detailed description

Phase 1a (Dose Escalation): The dose-escalation portion is designed to evaluate the safety, tolerability and MTD and/or RP2D of AVA6103, administered as monotherapy in two schedules: Day 1 of a 21-day cycle (Q3W schedule) and Day 1 of a 14-day cycle (Q2W schedule).

Phase 1b (Dose Expansion): The dose-expansion arm is based on review of data in the dose escalation phase, with AVA6103 administered at the RP2D.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AVA6103 in people with Vulvar Adenocarcinoma and PDAC - Pancreatic Ductal Adenocarcinoma, run by Avacta Life Sciences Ltd at 7 sites in United States.

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 29 inclusion and 27 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: looking for participants now, as of the sponsor's last update on 5 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. 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?

Contact Avacta Clinical Team (+44 (0)20 3911 0353, clinicaltrials@avacta.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events (AEs) (time frame: From Day 1 until up to 30 days after last dose of study drug.). 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 5 Oct 2026; AzTrials last refreshed its copy on 26 Oct 2026.
