About this study

Official title: An Open-label, Dose Escalation and Expansion, Phase 1/2 Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of TAK- 188, an Anti-CCR8 Antibody-Drug- Conjugate, as a Single Agent in Adult Participants With Locally Advanced or Metastatic Solid Tumors

TAK-188 is a new medicine that targets a protein called CCR8, which is found on the surface of certain cells (Tregs) inside tumors. These cells can weaken the body's ability to fight cancer. TAK-188 may help to remove these Tregs. Removing these Tregs may allow more cancer-fighting cells (CD8+ T cells) to attack the tumor and potentially stop tumors from growing.

In this study, researchers want to learn if TAK-188 can help the body's immune system better fight cancer in adults with advanced cancers which have not gotten better with regular treatments. The main aims of this study are to check if TAK-188 is safe in adults with advanced or spreading (metastatic) solid tumors, if participants tolerate the treatment with TAK-188 and to learn if TAK-188 works well in adults with certain advanced cancers after their previous treatments didn't work. Participants may receive TAK-188 for up to 1 year. Their health will be monitored after the treatment has ended for up to another year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase 1: Number of Participants with Treatment-emergent Adverse Events (TEAEs)

    An adverse event (AE) is any untoward medical occurrence in a participant administered a medicinal investigational drug. The untoward medical occurrence does not necessarily have to have a causal relationship with treatment. A TEAE is defined as an AE that occurs after administration of first dose of study drug and through 30 days after last dose of study drug or until start of subsequent antineoplastic therapy.

    Measured: From the signing of the informed consent form (ICF) through 90 days after the last dose (Up to approximately 16 months)

  2. Phase 1: Number of Participants with TEAEs Based on Severity

    An AE is any untoward medical occurrence in a participant administered a medicinal investigational drug. The untoward medical occurrence does not necessarily have to have a causal relationship with treatment. A TEAE is defined as an AE that occurs after administration of first dose of study drug and through 30 days after last dose of study drug or until start of subsequent antineoplastic therapy. Severity for each TEAE will be determined using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 5.0.

    Measured: From the signing of the ICF through 90 days after the last dose (Up to approximately 16 months)

  3. Phase 1: Number of Participants with Dose- limiting Toxicities (DLTs)

    DLTs will be evaluated according to NCI CTCAE, Version 5.0 except cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), will be graded according to American society for transplantation and cellular therapy (ASCST) Consensus Grading for CRS.

    Measured: Up to Cycle 1 (21 days)

  4. Phase 1: Number of Participants with Treatment-emergent Serious Adverse Events (SAEs)

    An AE is any untoward medical occurrence in a participant administered a medicinal investigational drug. The untoward medical occurrence does not necessarily have to have a causal relationship with treatment. An SAE is any untoward medical occurrence that results in death; is life-threatening; requires inpatient hospitalization or prolongation of present hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect or is a medically important event.

    Measured: From the signing of the ICF through 90 days after the last dose (Up to approximately 16 months)

  5. Phase 1: Number of Participants with Treatment-emergent Adverse Events Leading to Dose Modifications and Treatment Discontinuations

    Measured: From the signing of the ICF through 90 days after the last dose (Up to approximately 16 months)

  6. Phase 1b Backfill and Phase 2 Dose Expansion and Optimization: Overall Response Rate (ORR) as Assessed by the Investigator According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    ORR is defined as the percentage of participants who achieve Complete Response (CR) and Partial Response (PR) (determined by the investigator) during the study according to RECIST Version 1.1. CR is defined as the disappearance of all evidence of disease and PR is defined as regression of measurable disease by 30% and no new sites of disease. Stable disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).

    Measured: Up to 24 months

  7. Phase 1b Backfill and Phase 2 Dose Expansion and Optimization: Disease Control Rate (DCR)

    DCR is defined as the percentage of participants who achieve SD or better (CR+PR+SD determined by the investigator) equal to or more than (≥) 6 weeks during the study.

    Measured: Up to 24 months

  8. Phase 1b Backfill and Phase 2 Dose Expansion and Optimization: Duration of Response (DOR)

    DOR is defined as the time from the date of first documentation of a confirmed partial response (cPR) or better to the date of first documentation of PD or death for responders (cPR or better).

    Measured: Up to 24 months

Secondary outcomes (18)

  1. Phase 1: Recommended Dose for Expansion [RDE(s)] of TAK-188

    RDE will be based on the totality of safety, preliminary efficacy, pharmacokinetic (PK), and pharmacodynamic data from phase 1 dose escalation.

    Measured: Up to 12 months

  2. Phases 1 and 2: Cmax: Maximum Observed Plasma Concentration for TAK-188

    Measured: Up to end of treatment (approximately 13 months)

  3. Phases 1 and 2: Tmax: Time to Reach the Maximum Plasma Concentration (Cmax) for TAK-188

    DCR is defined as the percentage of participants who achieve SD or better (CR+PR+SD determined by the investigator) ≥6 weeks during the study.

    Measured: Up to 24 months

  11. Phase 1: Duration of Response (DOR)

    DOR is defined as the time from the date of first documentation of a cPR or better to the date of first documentation of PD or death for responders (cPR or better).

    Measured: Up to 24 months

  12. Phase 1: Time to Response (TTR)

    TTR is defined as the time from the date of first dose administration to the date of first documented cPR or better as determined by the investigator.

    Measured: Up to 24 months

  13. Phases 1 and 2: Change from Baseline in Regulatory T Cell (Treg) Abundance Within the Tumor Microenvironment (TME)

    Depletion of Treg will be determined using immunohistochemistry assessment in pretreatment and on-treatment tumor biopsy samples.

    Measured: Baseline, Cycle 2 Day 10 (Cycle length: 21 Days)

  14. Phases 1 and 2: Change from Baseline in Effector T Cell (Teff) Abundance Within the TME

    Increase in Teff [measured as cytotoxic T cell (CD8+ T cells)] within the TME will be evaluated using immunohistochemistry assessment in pretreatment and on-treatment tumor biopsy samples.

    Measured: Baseline, Cycle 2 Day 10 (Cycle length: 21 Days)

  15. Phases 1 and 2: Percentage of Participants Who Develop Anti-TAK-188 Antibodies

    Measured: Up to the end of treatment (approximately 13 months)

  16. Phase 1b Backfill and Phase 2 Dose Expansion and Optimization: Time to Response (TTR)

    TTR is defined as the time from the date of first dose administration to the date of first documented cPR or better as determined by the investigator.

    Measured: Up to 24 months

  17. Phase 1b Backfill and Phase 2 Dose Expansion and Optimization: Progression-free Survival (PFS)

    PFS is defined as the time from date of study treatment to the first documented PD based on RECIST v1.1, or death due to any cause, whichever occurs first.

    Measured: Up to 24 months

  18. Phase 1b Backfill and Phase 2 Dose Expansion and Optimization: Overall Survival (OS)

    OS is defined as the time from the date of first dose administration to the date of death, in all participants who received treatment on Cycle 1 Day 1 (C1D1).

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TAK-188 in people with Advanced or Metastatic Solid Tumors, run by Takeda 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 53 inclusion and 50 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 14 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 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 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?

Contact Takeda Contact (+1-877-825-3327, medinfoUS@takeda.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Number of Participants with Treatment-emergent Adverse Events (TEAEs) (time frame: From the signing of the informed consent form (ICF) through 90 days after the last dose (Up to approximately 16 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 NCT07205718.

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 14 Oct 2026.
