Efficacy of Everolimus-containing Chemotherapy in HER2 Negative Metastatic Breast Cancer Patients With PI3K/AKT/mTOR Mutations: A Retrospective Study

The study aimed to investigate the efficacy of the everolimus-containing chemotherapy in metastatic breast cancer patients with PI3K/AKT/mTOR mutations.14 cases of HER2- metastatic breast cancer patients with PI3K/AKT/mTOR mutations treated with everolimus-containing chemotherapy were retrospectively analyzed.The genetic profile in PI3K/AKT/mTOR pathway was studied.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The PI3K/AKT/mTOR pathway is frequently altered in breast cancer. Everolimus is a selective inhibitor of mammalian target of Rapamycin (mTOR).The benefit of everolimus in metastatic breast cancer patients with PI3K/AKT/mTOR mutations remains unclear, especially in TNBC patients. The study aimed to investigate the efficacy of the everolimus-containing chemotherapy in metastatic breast cancer patients with PI3K/AKT/mTOR mutations.

14 cases of HER2- metastatic breast cancer participants with PI3K/AKT/mTOR mutations treated with everolimus-containing chemotherapy were retrospectively analyzed.The genetic profile in PI3K/AKT/mTOR pathway was studied.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

25 years to 62 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Description

Inclusion Criteria:

  1. Patients with HER2- metastatic breast cancer
  2. Patients with PI3K/AKT/mTOR mutation

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PFS
Time Frame: The PFS was defined as the interval from the date of taking the everolimus-containing chemotherapy to the date of the first occurrence of disease progression or death from any cause,whichever came first, assessed up to 24 months.
Progression free survival
The PFS was defined as the interval from the date of taking the everolimus-containing chemotherapy to the date of the first occurrence of disease progression or death from any cause,whichever came first, assessed up to 24 months.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2021

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
