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.

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

Genders Eligible for Study

Female

Inclusion Criteria:

  • Histologically confirmed breast cancer with metastases
  • Tumor that has overexpression of HER2 as documented by being either FISH-positive or HER2/neu 3+ confirmed by immunohistochemistry
  • Patients may have had up to three prior chemotherapy regimens for metastatic disease, which may have been given in combination with Herceptin® and which may have been discontinued due to toxicities. In addition, patients may have had adjuvant chemotherapy.
  • Phase II only: Must have measurable disease by RECIST criteria (defined in section 8) with at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as > 20 mm with conventional techniques, or as > 10 mm with spiral CT scan

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
Time Frame
Phase I: To evaluate the safety and tolerability of several dose levels of CPG 7909 (up to a maximum of 0.16 mg/kg) and to determine the maximum tolerated dose (MTD)* of CPG 7909 in combination with Herceptin®
Time Frame: 24 weeks
24 weeks
Phase II: To evaluate tumor response and safety of CPG 7909 (at the MTD as determined in Phase I) in combination with Herceptin® in patients with metastatic breast cancer.
Time Frame: 24 weeks
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 Frame
Phase I To evaluate tumor response, duration of response, time to disease progression, ECOG performance status, and survival time.
Time Frame: 24 weeks
24 weeks
Phase II To evaluate duration of response, time to disease progression, ECOG performance status, and survival time.
Time Frame: 24 weeks
24 weeks

Study Major Dates

Study Start

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.
September 1, 2002

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.
