About this study

Official title: A Phase 2 Study of TAS-117 in Patients With Advanced Solid Tumors Harboring Germline PTEN Inactivating Mutations

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of TAS-117 in patients with advanced or metastatic solid tumors (excluding primary brain tumors) harboring germline PTEN inactivating mutations.

Read the detailed description

Study TAS-117-201 is an open-label, single-arm Phase 2 study evaluating the efficacy, safety, tolerability, pharmacokinetics, and pharmacodynamics of TAS-117 in patients with advanced or metastatic solid tumors harboring germline PTEN inactivating mutations. The study will be conducted in two parts:

  • Part A: Safety lead-in (Dose Escalation and Dose Regimen Confirmation)
  • Part B: Single-arm Phase 2 study

Patients will receive TAS-117 orally every day or intermittently on a 21-day cycle

  • Part A (Dose Escalation): up to 36 adult patients with advanced or metastatic solid tumors (excluding primary brain tumors) irrespective of gene alterations. The Dose Escalation consists of 2 cohorts: Daily Dose Regimen and Intermittent Dose Regimen.
  • Part A (Dose Regimen Confirmation): approximately 6 adult or adolescent patients with advanced or metastatic solid tumors (excluding primary brain tumors) harboring germline PTEN inactivating mutations
  • Part B (Phase 2): approximately 54 adult or adolescent patients with advanced or metastatic solid tumors (excluding primary brain tumors) harboring germline PTEN inactivating mutations

Treatment will continue until disease progression, unacceptable toxicity, or any other of the criteria for treatment discontinuation is met. For patients who discontinue treatment for reasons other than disease progression, tumor assessments should be continued until radiologic disease progression is documented or until initiation of subsequent new anticancer therapy (whichever occurs first).

Patients will be followed for survival every 12 weeks (±2 weeks) until survival events (deaths) have been reported for 75% of enrolled patients or the study is terminated early by the Sponsor.

What is being measured

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

  1. Incidence of treatment-emergent adverse events and dose-limiting toxicities (safety and tolerability) and MTD of TAS-117 in Part A

    Number of patients with abnormal laboratory values, treatment emergent AEs, abnormal vital signs and ECG, and Dose-limiting toxicities (DLTs)

    Measured: 21 days for DLT evaluation, approximately 7 months for the others

  2. Recommended Phase 2 Dose (RP2D) of TAS-117 in Part A

    Measured: 21 days for DLT evaluation, approximately 7 months for the others

  3. Objective Response Rate (ORR) in Part B (including all patients with germline PTEN mutations in Part A)

    ORR, defined as the proportion of patients experiencing a best overall response of CR or PR per RECIST 1.1.

    Measured: Approximately 6 months

Secondary outcomes (10)
  1. Incidence of treatment-emergent adverse events (safety) in Part B

    Number of patients with abnormal laboratory values, treatment-emergent AEs, abnormal vital signs and ECG

    Measured: Approximately 7 months

  2. Disease Control Rate (DCR)

    DCR, defined as the proportion of patients experiencing a best overall response of stable response (SD), PR, or complete response (CR).

    Measured: Approximately 6 months

  3. Duration of Response (DOR)

    DOR, defined as the time from the first documentation of response (CR or PR) to the first documentation of objective tumor progression or death due to any cause, whichever occurs first.

    Measured: Approximately 6 months

  4. Progression Free Survival (PFS)

    PFS, defined as the time from date of the first dose of study treatment to the date of disease progression based on Investigator assessment of radiographic images or death, whichever occurs first.

    Measured: Approximately 6 months

  5. Overall Survival (OS)

    OS, defined as the time from the date of first dose to the death date.

    Measured: Approximately 12 months

  6. Pharmacokinetics (PK) profile of TAS-117 in Part A

    maximum plasma concentration (Cmax)

    Measured: 21 days

  7. Pharmacokinetics (PK) profile of TAS-117 in Part A

    area under the plasma concentration-time curve (AUC)

    Measured: 21 days

  8. Pharmacokinetics (PK) profile of TAS-117 in Part A

    time to reach maximum plasma concentration (Tmax)

    Measured: 21 days

  9. Pharmacokinetics (PK) profile of TAS-117 in Part A

    terminal elimination half-life (T1/2)

    Measured: 21 days

  10. Pharmacodynamics (PD) profile of TAS-117 in Part A

    Evaluate Total and Phosphorylated AKT and PRAS40

    Measured: 21 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TAS-117 in people with Advanced or Metastatic Solid Tumors Irrespective of Gene Alterations and Advanced or Metastatic Solid Tumors With Germline PTEN Inactivating Mutations, run by Taiho Oncology, Inc. at 8 sites in 4 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 13 inclusion and 6 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 4 Sep 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 United States, Austria, France, United Kingdom. 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: The Sponsor had decided to terminate this clinical trial due to an insufficient rate of accrual of patients.). 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 treatment-emergent adverse events and dose-limiting toxicities (safety and tolerability) and MTD of TAS-117 in Part A (time frame: 21 days for DLT evaluation, approximately 7 months for the others). The study lists 3 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 NCT04770246, 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 4 Sep 2024.
