Trial summary

ASP2074 is a potential new treatment for people with certain solid tumors. Before ASP2074 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This information will help find a suitable dose and check for potential medical problems from the treatment. Read more about this study

About this study

Official title: A Phase 1/1b Study of ASP2074 in Participants With Metastatic or Locally Advanced Solid Tumors

ASP2074 is a potential new treatment for people with certain solid tumors. Before ASP2074 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This information will help find a suitable dose and check for potential medical problems from the treatment. People in this study will be adults with metastatic or locally advanced solid tumors. Metastatic means the cancer has spread to other parts of the body. They will have been previously treated with all available standard therapies and they may no longer be benefitting from further treatment.

There are 2 main aims of this study. The first is to learn if people with certain solid tumors have any medical problems after receiving different doses of ASP2074. The second is to find a suitable dose of ASP2074 to use in future studies.

This study will be in 2 parts.

In Part 1, different small groups of people will receive lower or higher doses of ASP2074. Any medical problems will be recorded at each dose. This is done to find suitable doses of ASP2074 to use in Part 2 of the study. The first group will receive the lowest dose of ASP2074. A medical expert panel will check the results from this group and decide if the next group can receive a higher dose of ASP2074. The panel will do this for each group until all groups have taken ASP2074 or until suitable doses have been selected for Part 2.

In Part 2, other different small groups of people will receive ASP2074 with the most suitable doses worked out from Part 1. This will help find a more accurate dose of ASP2074 to use in future studies.

ASP2074 will be given as an infusion on the first day of each treatment cycle. The people in this study will have treatment cycles until: they have medical problems from the treatment; their cancer gets worse; they start other cancer treatment; they ask to stop treatment; or they do not come back for treatment.

People will visit the clinic on certain days during their treatment, with extra visits during the first 2 cycles of treatment. During these visits, the study doctors will check for any medical problems from ASP2074. At some visits, other checks will include a medical examination, laboratory tests and vital signs. Vital signs include temperature, pulse, and blood pressure. Also, blood and urine samples will be taken. Electrocardiograms will be done to check the heart rhythm during the study. Tumor samples will be taken during certain visits before treatment begins, during treatment, and when treatment has finished.

People will visit the clinic within 7 days after stopping treatment. The study doctors will check for any medical problems from ASP2074. Other checks will include a medical examination, laboratory tests and vital signs. Then, people may visit the clinic at 30 days after stopping treatment. Thirty and 90 days after the last dose, the study doctors will check for any medical problems from ASP2074. People will have their vital signs checked and have some laboratory tests. After this, people will continue to visit the clinic every 6 weeks. This is to check the condition of their cancer. They will do this until their cancer is worse, they start other cancer treatment, they ask to leave the study, or they do not come back for treatment. Then, the study doctors will call every 12 weeks for up to 1 year or until that person asks to leave the study, the study is stopped, or the person cannot be reached.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ASP2074 in people with Advanced Solid Tumors, run by Astellas Pharma Global Development, Inc. at 13 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 17 inclusion and 30 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: stopped early, as of the sponsor's last update on 20 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, 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 was stopped early (reason given: Company Strategic Reasons). Results are not available in the source record.

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 of Dose Limiting Toxicities (DLTs) for ASP2074 (time frame: Up to up to 28 Days). The study lists 6 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 NCT05646797.

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 20 Oct 2025.
