Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

Multicenter, phase III, open-label, randomized clinical trial, which will include 494 patients randomized to two neoadjuvant chemotherapy arms. The treatment protocol will be the same in both groups, only the regimens sequences will be evaluated: starting with anthracycline versus taxane, with or without carboplatin for patients with triple negative subtype. The chemotherapy regimen will follow the institution's routine, which includes the use of CA in the anthracyclical phase and, in the taxane phase, the use of docetaxel every 21 days or weekly paclitaxel. The rest of the treatment (surgery, radiotherapy, hormone therapy) will not be part of the study and will be carried out according to institutional guidelines.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • The participant (or legally acceptable representative, if applicable) provides written informed consent for the study;
  • The participant must agree to use a contraceptive as detailed in Appendix B of this protocol during the treatment period and for at least 120 days after the last dose of the study treatment;
