Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Patients will receive CT-P6 or Herceptin every 3 weeks.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Herceptin & Paclitaxel

Herceptin was administered at a loading dose of 8 mg/kg body weight by IV infusion over 90 minutes on Day 1, Cycle 1, then at 6 mg/kg repeated at 3-weekly intervals until disease progression, death or discontinuation.

Paclitaxel was administered at a dose of 175 mg/m2 BSA as a continuous 3-hour IV infusion on the day following the first dose of study drug (Herceptin). If the first dose of study drug was well tolerated, subsequent doses of paclitaxel were given immediately after the next dose of study drug. Paclitaxel cycles were repeated every 3 weeks until disease progression, death or discontinuation.
Drug: Herceptin
Administered every 3 weeks
Other Names:
  • Trastuzumab
Drug: Paclitaxel
Administered every 3 weeks
Experimental: CT-P6 & Paclitaxel

CT-P6 was administered at a loading dose of 8 mg/kg body weight by intravenous (IV) infusion over 90 minutes on Day 1, Cycle 1, then at 6 mg/kg repeated at 3-weekly intervals until disease progression, death or discontinuation.

Paclitaxel was administered at a dose of 175 mg/m2 body surface area (BSA) as a continuous 3-hour IV infusion on the day following the first dose of study drug (CT-P6). If the first dose of study drug was well tolerated, subsequent doses of paclitaxel were given immediately after the next dose of study drug. Paclitaxel cycles were repeated every 3 weeks until disease progression, death or discontinuation.
Drug: CT-P6
Administered every 3 weeks
Drug: Paclitaxel
Administered every 3 weeks

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
Objective Response Rate
Time Frame: 6 months (up to 24 weeks)
Best Overall Response (BOR) was derived from the overall response across all time points until after Cycle 8 using Independent Tumor Review Committee (ITRC) data in the FAS. Objective Response Rate (ORR) was defined as the number of patients with a BOR of complete response (CR) or partial response (PR) divided by the number of patients in the corresponding population, as assessed by Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1.
6 months (up to 24 weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time to Progression
Time Frame: Through study completion, approximately 40 months
Time from randomization to determined progressive disease, as assessed by RECIST version 1.1.
Through study completion, approximately 40 months
Time to Response

Progression Free Survival
Time Frame: Through study completion, approximately 40 months
Time from randomization to radiological progression or death from any cause, as assessed by RECIST 1.1

Overall Survival
Time Frame: Through study completion, approximately 40 months
The number of days between the date of randomization and the date of death from any cause.

Safety Endpoints; Immunogenicity
Time Frame: During treatment, median of 13 cycles (every cycle is 3 weeks)
Assessed by the proportion of patients with development of antibodies to study drug (positive anti-drug antibody [ADA] results after the first study drug infusion)
During treatment, median of 13 cycles (every cycle is 3 weeks)
Pharmacokinetic Endpoints; Ctroughss
Time Frame: predose and at 1.5 hours (end of infusion) of each cycle

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.
