Pilot Study of Docetaxel & Bevacizumab +/- Trastuzumab in First-Line Treatment of Patients With Metastatic Breast Cancer

20. juli 2012 opdateret af: Sanofi

A Pilot, Phase II, Multicenter, Open-Label, Prospective Evaluation of Docetaxel and Bevacizumab ± Trastuzumab in the First-Line Treatment of Patients With Metastatic Breast Cancer

Pilot, phase II, parallel-group, open-label, noncomparative, prospective, multicenter study designed to evaluate the progression-free survival of docetaxel and bevacizumab ± trastuzumab for the first-line treatment of participants with metastatic breast cancer. Participants were stratified according to human epidermal growth factor receptor-2 (HER2) status at the time of enrollment. HER2 negative participants were assigned to receive docetaxel and bevacizumab (DB). HER2 positive participants were assigned to receive docetaxel, bevacizumab, and trastuzumab (DBT).

All participants (except one) were off study treatment on 30 June 2011. All efficacy analysis and safety analysis was performed using the cut-off date of June 2011. One participant continued treatment till 11 March 2012. For this participant, adverse events were collected upto 19 April 2012 and included in the safety analysis.

Beskrivelse

The following information on clinical trials is provided for information purposes only to allow participants and physicians to have an initial discussion about the trial. This information is not intended to be complete information about the trial, to contain all considerations that may be relevant to potential participation in the trial, or to replace the advice of a personal physician or health professional.

INCLUSION CRITERIA:

  1. Histologically or cytologically proven adenocarcinoma of the breast at first diagnosis
  2. Stage IV disease with at least one measurable lesion according to the RECIST criteria
  3. HER2/neu positive as determined by 3+ immunohistochemistry (IHC) staining or fluorescence in situ hybridization (FISH) positivity or negative tumors

  10. Subjects receiving bisphosphonate therapy; however, if bisphosphonates were started within <2 months prior to treatment the bone lesions will not be evaluated for response, and the subjects must have another site of metastatic disease that is either measurable or evaluable for response

EXCLUSION CRITERIA:

  1. Prior chemotherapy for metastatic breast cancer
  2. Prior treatment with bevacizumab or other anti-VEGF therapy
  3. Concurrent treatment with any other non-protocol anticancer therapy with the exception of radiation therapy as long as all target lesions being followed are not in the radiation field and if HER2/neu positive, HER2/neu-directed therapy
  4. Current or prior history of brain or leptomeningeal metastases
  5. Presence of neuropathy >/= 2
  6. Presence of any non-healing wound, fracture, or ulcer, or the presence of clinically significant (>/= Grade 2) peripheral vascular disease
  7. History of any other malignancy within the past 5 years, with the exception of non-melanoma skin cancer or carcinoma in-situ of the cervix
  8. Clinically significant cardiovascular disease
  9. Active peptic ulcer disease, inflammatory bowel disease, or other gastrointestinal condition increasing the risk of perforation; history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to beginning therapy
  10. History of bleeding diathesis or coagulopathy

Foranstaltningsbeskrivelse
Tidsramme
Progression-free Survival (PFS) Rate: Percentage of Participants With PFS
Tidsramme: Up to 6 months and 12 months after treatment initiation

PFS was the time from registration to first documentation of

  • progressive disease (PD) based on Response Evaluation Criteria in Solid Tumors (RECIST) - criteria pre-defining changes in lesion size or appearance
  • symptomatic deterioration
  • death due to any cause (in absence of PD).

The Percentage of participants with PFS is reported.

For the analysis, participants were censored

  • on the last available tumor assessment date on study treatment if they

    • had no PFS event
    • were on anticancer therapy not related to study treatment

  • on the registration date if they

    • did not receive study drug
    • had no post baseline tumor assessment
Up to 6 months and 12 months after treatment initiation
Time to Progression-free Survival (PFS)
Tidsramme: From treatment initiation to PFS event (up to June 2011)

Time to PFS was the interval from the date of registration to the earliest of the following documented dates:

  • PD as defined by RECIST (criteria pre-defining changes in lesion size or appearance)
  • symptomatic deterioration
  • death.

Time to PFS was estimated from Kaplan-Meier Plots.
From treatment initiation to PFS event (up to June 2011)

Tidsramme
Confirmed Overall Response (OR) Based on RECIST Criteria
Tidsramme: From treatment initiation to June 2011

Confirmed OR was confirmed Complete Response (CR) + confirmed Partial Response (PR). According to RECIST

  • CR was the disappearance of all tumor lesions
  • PR was a pre-defined decrease in the size of tumor lesions.

To determine a response, radiologic tumors assessments were performed using computed tomography (CT) and/or magnetic resonance imaging (MRI) of the chest, and the abdomen, bone scan or positron emission tomography (PET) scan, and other imaging techniques as clinically indicated. To confirm a response, 2 assessments separated by 28 days or more were required.
From treatment initiation to June 2011
Number of Participants With Confirmed Clinical Benefit Based on RECIST Criteria
Tidsramme: From treatment initiation to June 2011

Clinical Benefit (CB) was achieved in participants with a response (CR + PR) or a stable disease (SD).

According to RECIST

  • CR was the disappearance of all tumor lesions
  • PR was a pre-defined decrease in the size of tumor lesions
  • SD was neither sufficient decrease in tumor size to qualify for PR or sufficient increase to qualify for PD.

Confirmation of a response needed 2 responses scored, separated by 28 days or more (for CR and PR), and by 26 weeks or more (for SD).
From treatment initiation to June 2011
Duration of Response (DR)
Tidsramme: From treatment initiation to June 2011

DR was the interval from date of initial documented confirmed response (CR or PR) to the first documented confirmed date of disease progression (PD) or death from any cause in the absence of previous documentation of objective tumor progression.

Participants who were alive and without any record of PD at the time of discontinuation were censored at the last available tumor assessment date; participants with non-study anti-cancer therapy during the study were censored at the last available tumor assessment date prior to the anti-cancer therapy.

DR was estimated from Kaplan-Meier Plots.
From treatment initiation to June 2011
Overall Survival (OS) Time
Tidsramme: From treatment initiation to June 2011

OS was the interval between the date of study entry and the date of death from any cause. In the absence of confirmation of death, survival time was censored at the last date the participant was known to be alive.

OS time was estimated from Kaplan-Meier Plots.
From treatment initiation to June 2011
Number of Participants With Adverse Events (AE)
Tidsramme: From treatment initiation to 30 days after the last dose of study treatment

An adverse event (AE) was any unfavorable and unintended sign, symptom, syndrome, or illness that developed or worsened during the clinical study. AEs occurring on or after first dose of study medication inclusive to 30 days post-last dose were the treatment emergent adverse events (TEAEs).

An serious adverse event was an AE that at any dose (including overdose) resulted in death, was life-threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability or incapacity, was a congenital anomaly, and/or was medically important.
From treatment initiation to 30 days after the last dose of study treatment
