What is being measured

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

  1. Safety and tolerability of ACTR T cell product with trastuzumab as assessed by committee review of dose limiting toxicities (DLTs), incidence and severity of adverse events (AEs) and clinically significant abnormalities of laboratory values

    Measured: 42 days

  2. Determination of recommended phase 2 dose (RP2D) regimen

    Review of DLTs, maximum tolerated dose (MTD), incidence and severity of AEs and clinically significant abnormalities of laboratory values

    Measured: 42 days

Secondary outcomes (10)
  1. Anti-tumor activity as measured by overall response rate (ORR) per iRECIST

    Measured: 52 weeks

  2. Anti-tumor activity as measured best overall response (BOR)

    Measured: 52 weeks

  3. Anti-tumor activity as measured by duration of response (DOR)

    Measured: 52 weeks

  4. Anti-tumor activity as measured by progression-free survival (PFS)

    Measured: 52 weeks

  5. Anti-tumor activity as measured by overall survival (OS)

    Measured: 52 weeks

  6. Assessment of persistence of ACTR as measured by flow cytometry

    Measured: 52 weeks

  7. Assessment of persistence of ACTR as measured by quantitative polymerase chain reaction (qPCR)

    Measured: 52 weeks

  8. Assessment of ACTR phenotype and function as measured by flow cytometry

    Measured: 52 weeks

  9. Assessment of induction of inflammatory markers and cytokines/chemokines after ACTR T cell product administration

    Levels of inflammatory markers, cytokines/chemokines in blood

    Measured: 52 weeks

  10. Trastuzumab pharmacokinetics (PK)

    trastuzumab serum concentration, Area Under the Curve (AUC), trough levels

    Measured: 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ACTR T Cell Product and Trastuzumab in people with Solid Tumor and HER-2 Protein Overexpression, run by Cogent Biosciences, Inc. at 6 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 14 inclusion and 15 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 31 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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?

The study was stopped early (reason given: Business 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?

Safety and tolerability of ACTR T cell product with trastuzumab as assessed by committee review of dose limiting toxicities (DLTs), incidence and severity of adverse events (AEs) and clinically significant abnormalities of laboratory values (time frame: 42 days). 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 31 Mar 2020.
