About this study

Official title: A Phase 1 Study of ASP1002 in Participants With Metastatic or Locally Advanced Solid Tumors

ASP1002 is being studied in people with tumors that have spread to nearby tissue (locally advanced) that cannot be removed by surgery (unresectable) or tumors that have spread to other parts of the body (metastatic). Claudin 4 protein, or CLDN4, is a protein found on tumors in different parts of the body. ASP1002 is thought to work by attaching to the CLDN4 protein in the tumor. This switches on the body's immune system to attack the tumor.

Before ASP1002 can be used, researchers need to collect information about the safety of ASP1002 and how people with tumors tolerate it. In this study, ASP1002 will be given to humans for the first time. It will either be given by itself or together with other cancer treatments. These include standard chemotherapies (mFOLFOX6, FOLFIRI, TAS-102, pemetrexed, carboplatin, and docetaxel) and immunotherapies (bevacizumab, pembrolizumab, and ramucirumab). Immunotherapy is a treatment that works with the body's immune system to treat tumors.

This is an early development study. These studies are mostly about safety, but also to find the most suitable dose. Other aims are to learn if ASP1002 shows signs of slowing down tumor growth, to learn how the body processes ASP1002, and to check if there are changes in the CLDN4 protein or the immune system after treatment.

The main aims of the study are to check the safety of ASP1002 by itself and given with standard chemotherapies and immunotherapies in people with solid tumors and how well they tolerate the study treatments, and to find a suitable dose of ASP1002 by itself and in combination with standard chemotherapies and immunotherapies.

People in this study will be adults with tumors that have spread to nearby tissue (locally advanced) that cannot be removed by surgery (unresectable) or tumors that have spread to other parts of the body (metastatic). They will have been previously treated with available standard therapies, or they will have refused to receive those treatments.

The key reasons people cannot take part are if they have symptoms of cancer in the brain or nervous system, have recently had other cancers that required treatment, or have diseases that affect the immune system or the heart.

This study will be in 2 parts. In Part 1, different small groups of people will receive lower to higher doses of ASP1002 by itself and given with chemotherapies and immunotherapies. Any medical problems will be recorded at each dose. This is done to find suitable doses of ASP1002 to use in Part 2 of the study.

In Part 2, other different small groups of people will receive doses of ASP1002, the chemotherapies and immunotherapies that worked the best in Part 1.

In both parts of the study, ASP1002 will be given by itself and with standard chemotherapies and immunotherapies to people slowly through a tube into a vein. This is called an infusion. This will happen every 2 to 4 weeks, in treatment cycles. Treatment cycles may be 21 or 28 days long. People will continue to receive study treatment for up to 2 years or until their cancer gets worse, they can't tolerate the study treatment, they start other cancer treatments, or the doctor decides the person should stop receiving study treatment, or sadly, they pass away. They can also choose to stop taking the study treatment at any time without giving a reason.

During the study, people will visit the clinic several times for a health check. This includes standard safety checks and reporting any medical problems. Every 2 months, the study doctors will check if each person's cancer has stayed the same, shrunk or disappeared over time. This will be done by scans (CT or MRI scans). Tumor samples will be taken during the study, and people will have the option of giving a tumor sample after study treatment has finished.

People will have follow-up health checks for up to 1 year after their last dose of study treatment or until they start a different study treatment on a new study, whichever happens first.

    Comparison of CLDN4 expression at baseline versus on-treatment tumor biopsies will be performed.

    Measured: Baseline and up to 6 weeks

  13. Radiographic disease progression

    Radiographic disease progression will be assessed by CT/MRI per RECIST v1.1 and iRECIST, and by bone scan according to PCWG4 criteria (applicable for evaluation of bone lesions in participants with mAPMR-PCa).

    Measured: Baseline and up to 28 months

  14. Prostate-Specific Antigen (PSA) Response Rate (PSA50)

    PSA response will be assessed per Prostate Cancer Working Group 3 (PCWG3) criteria for metastatic androgen pathway modulation resistant (mAMPR) prostate cancer participants. Percentage of participants with a ≥50% decrease from baseline in PSA levels, confirmed by a subsequent assessment at least 3 weeks later.

    Measured: Baseline and up to 28 months

  15. Time to PSA Progression

    PSA testing will be performed for mAMPR prostate cancer participants. Time from baseline (or PSA nadir) to first documented increase in PSA, confirmed by a second rising value at least 3 weeks later. A minimum rise of 0.2 ng/mL is required.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ASP1002, Bevacizumab and Oxaliplatin in people with Advanced Solid Tumors, run by Astellas Pharma Global Development, Inc. at 15 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 79 inclusion and 32 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 23 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 15 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 Astellas Pharma Global Development, Inc. (800-888-7704, Astellas.registration@astellas.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Dose Limiting Toxicities (DLTs) for ASP1002 (time frame: Up to 24 months). The study lists 8 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 NCT05719558.

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 23 Jul 2026.
