About this study

Official title: An Open-label, Randomized, Phase 1 Safety and Pharmacokinetic Study of Enfortumab Vedotin (ASG-22CE) in Japanese Patients With Locally Advanced or Metastatic Urothelial Carcinoma

The objective of this study is to assess the safety, tolerability and pharmacokinetics of enfortumab vedotin (ASG-22CE) when administered intravenously to Japanese subjects with locally advanced or metastatic urothelial carcinoma. This study will also assess the immunogenicity as defined by the incidence of anti-drug antibody (ADA) and anti-tumor activity of enfortumab vedotin (ASG-22CE) when administered intravenously to Japanese subjects with locally advanced or metastatic urothelial carcinoma.

Read the detailed description

All subjects will receive a single 30 minute intravenous (IV) infusion of enfortumab vedotin (ASG-22CE) once weekly for 3 weeks of every 4 weeks (i.e., on Days 1, 8, and 15). A cycle is 28 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Enfortumab vedotin in people with Metastatic Urothelial Cancer, run by Astellas Pharma Inc at 8 sites in Japan.

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 5 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 18 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Japan. 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?

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?

Safety assessed by incidence of adverse events (time frame: Up to 12 months). The study lists 25 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 NCT03070990, which also lists 1 linked publication.

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 Oct 2024.
