About this study

Official title: Trial of Tucidinostat in Combination With Fulvestrant in Patients With Hormone-receptor Positive Advanced Breast Cancer

The purpose of the study is evaluate the efficacy and safety of tucidinostat in combination with fulvestrant in patients with hormone-receptor positive advanced breast cancer.

Read the detailed description

Hormone-receptor positive breast cancer is the most common subtype in breast cancer. Tucidinostat is an oral subtype-selective histone deacetylase inhibitor, which showed preliminary signs of encouraging anti-tumour activity in patients with advanced hormone-receptor positive breast cancer in the previous studies. The aim of this study is to evaluate the efficacy and safety of Tucidinostat in combination with fulvestrant in patients with recurrent or metastatic hormone-receptor positive breast cancer.

What is being measured

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

  1. Progression Free Survival (PFS)

    PFS was defined as the time from treatment until objective disease progression according to Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST 1.1), or death by any cause, whichever is first met.

    Measured: From date of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years.

Secondary outcomes (5)

  1. overall survival (OS)

    Defined as from the date of treatment to date of death, irrespective of cause.

    Measured: Time from treatment to death from any cause, assessed up to 3 years.

  2. Objectivel response rate (ORR)

    Defined as numbers of patients achieved complete response and partial response of treatment.

    Measured: Response is assessed once every 8 weeks, from the day of treatment to the date of first documented progression, assessed up to 3 years.

  3. Duration of response (DOR)

    Defined as from the first date when criteria for response is met until the first date when the criteria for progression or death is met.

    Measured: From the day of treatment to the date of first documented progression, assessed up to 3 years.

  4. 4.Clinical Benefit Rate (CBR)

    ORR is defined as percentage of participants with Complete Response, Partial Response or Stable Disease≥24 weeks, assessed by the investigators according to the RECIST v1.1.

    Measured: From the day of treatment to the date of first documented progression, assessed up to 3 years.

  5. Adverse event(AE)

    Adverse event related to treatment.

    Measured: From the day of treatment to the date of first documented progression, assessed up to 3 years.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tucidinostat and Fulvestrant in people with Breast Cancer, run by Guangdong Women and Children Hospital.

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 10 inclusion and 16 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: status not confirmed, as of the sponsor's last update on 11 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Anqin Zhang (020-39151519, sfyrxzx@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression Free Survival (PFS) (time frame: From date of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years.). 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 NCT04999540, which also lists 10 linked publications.

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 11 Aug 2021.
