I-SPY 2 TRIAL: Neoadjuvant and Personalized Adaptive Novel Agents to Treat Breast Cancer

  • Study type:

    Interventional What is this?

    Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • Study phase:

    II What is this?

    During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  • Histologically confirmed invasive cancer of the breast
  • Clinically or radiologically measureable disease in the breast after diagnostic biopsy, defined as longest diameter greater than or equal to 25 mm (2.5cm)
  • No prior cytotoxic regimens are allowed for this malignancy. Patients may not have had prior chemotherapy or prior radiation therapy to the ipsilateral breast for this malignancy. Prior bis-phosphonate therapy is allowed
  • Age ≥18 years
  • ECOG performance status 0-1
  • Willing to undergo core biopsy of the primary breast lesion to assess baseline biomarkers
  • Non-pregnant and non-lactating
  • No ferromagnetic prostheses. Patients who have metallic surgical implants that are not compatible with an MRI machine are not eligible.
  • Ability to understand and willingness to sign a written informed consent (I-SPY TRIAL Screening Consent)
  • Eligible tumors must meet one of the following criteria: Stage II or III, or T4, any N, M0, including clinical or pathologic inflammatory cancer or Regional Stage IV, where supraclavicular lymph nodes are the only sites metastasis
  • Any tumor ER/PgR status, any HER-2/neu status as measured by local hospital pathology laboratory and meets any tumor assay profile described in protocol section 4.1.2F
  • Normal organ and marrow function: Leukocytes ≥ 3000/μL, Absolute neutrophil count ≥ 1500/μL, Platelets ≥ 100,000/μL, Total bilirubin within normal institutional limits, unless patient has Gilbert's disease, for which bilirubin must be ≤ 2.0 x ULN, AST(SGOT)/ALT (SGPT) ≤ 1.5 x institutional ULN, creatinine < 1.5 x institutional ULN
  • No uncontrolled or severe cardiac disease. Baseline ejection fraction (by nuclear imaging or echocardiography) must by ≥ 50%
  • No clinical or imaging evidence of distant metastases by PA and Lateral CXR, Radionuclide Bone scan, and LFTs including total bilirubin, ALT, AST, and alkaline phosphatase
  • Tumor assay profile must include on of the following: MammaPrint High, any ER status, any HER2 status, or MammaPrint Low, ER negative (<5%), any HER2 status, or MammaPrint Low, ER positive, HER2/neu positive by any one of the three methods used (IHC, FISH, TargetPrint™)
  • Ability to understand and willingness to sign a written informed consent document (I-SPY 2 TRIAL Consent #2)

Exclusion Criteria:

  • Use of any other investigational agents within 30 days of starting study treatment
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to the study agent or accompanying supportive medications.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
