Primary Purpose: Treatment
Official Title: A Randomized, Double-blind, Controlled Phase III Study of Stimuvax® (L-BLP25 or BLP25 Liposome Vaccine) in Combination With Hormonal Treatment Versus Hormonal Treatment Alone for First-line Therapy of Post-menopausal Women With Estrogen Receptor (ER)-Positive and/or Progesterone Receptor (PgR)-Positive, Inoperable Locally Advanced, Recurrent, or Metastatic Breast Cancer

Primary Outcome Measures:
  • Progression-Free Survival (PFS) time will be analyzed as the main measure of treatment outcome. PFS time is defined as the the duration from randomization to first observation of PD by the independent radiologic review or death. [ Time Frame: first assessment (of PFS) after 15 month; then on an ongoing basis ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Measurement Response Evaluation Criteria in Solid Tumours (RECIST) [ Time Frame: Pre-Treatment Visit, every 8 weeks thereafter, starting with week 14 during the Maintenance Treatment, and at the End of Study visit. ] [ Designated as safety issue: No ]

Enrollment: 42
Study Start Date: June 2009
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Investigational Arm

Investigational Arm:

  • Pretreatment (Single Dose): 300 mg/m2 of IV cyclophosphamide
  • L-BLP25 plus Hormonal Therapy (Standard Dose)
Biological: Stimuvax (L-BLP 25 or BLP25 liposome vaccine) and Hormonal Treatment

Investigational Arm:

Pretreatment (Single Dose) 300 mg/m2 of IV cyclophosphamide in investigational arm

Primary treatment phase:

Hormonal treatment plus 8 consecutive weekly subcutaneous vaccinations with 1000 µg* L-BLP25 (week 1 to 8)

Maintenance treatment phase:

Hormonal treatment plus vaccinations with 1000 µg* L-BLP25 at six-week intervals beginning at week 14 and continued until Progressive Disease (PD)

*calculated as mass of lipopeptide (antigen)

Drug: cyclophosphamide
300 mg/m2 of IV cyclophosphamide
Active Comparator: Control Arm:

Control Arm:

  • Pretreatment (Single Dose): 0.9% sodium chloride infusion
  • Placebo plus Hormonal Therapy (Standard Dose)
Biological: Placebo of Stimuvax (L-BLP 25 or BLP25 liposome vaccine) and Hormonal Treatment

Control Arm:

Pretreatment (Single Dose) 0.9% NaCl infusion as placebo

Primary treatment phase:

Hormonal therapy plus 8 consecutive weekly subcutaneous vaccinations with Placebo (week 1 to 8)

Maintenance treatment phase:

Hormonal therapy plus Vaccinations with Placebo at six-week intervals beginning at week 14 and continued until Progressive Disease (PD)

Drug: sodium chloride
0.9% sodium chloride infusion

Detailed Description:

The purpose of the study is to determine whether the addition of the experimental cancer vaccine Stimuvax to hormonal treatment is effective in prolonging progression-free survival in postmenopausal women with endocrine-sensitive inoperable locally advanced, recurrent or metastatic breast cancer.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Postmenopausal women
  • ER+ and/or PgR+, histologically or cytologically confirmed primary carcinoma of the breast
  • Expressing at least one of the following five HLA haplotypes, as centrally assessed by HLA genotyping from whole blood: HLA-A2, -A3, -A11, -B7, or -B35
  • Locally advanced, recurrent, or metastatic breast cancer (Subject must have at least one lesion not located in bone).
  • Measurable disease by RECIST, and inoperable
  • ECOG performance status of 0 or 1
  • Adequate hematologic, hepatic, and renal function within two weeks prior to initiation of therapy, as defined by the protocol

Exclusion Criteria:

Disease Status

  • PD either during hormonal therapy for early breast cancer (adjuvant therapy) or within 12 months of completing such therapy
  • Human epidermal growth factor receptor 2-positive (HER2+) breast cancer
  • Autoimmune disease that in the opinion of the investigator could compromise the safety of the subject in this study. (Exception will be granted for well-controlled Type I diabetes mellitus.)
  • Recognized immunodeficiency disease, including cellular immunodeficiencies, hypogammaglobulinemia or dysgammaglobulinemia; hereditary or congenital immunodeficiencies
  • Past or current history of malignant neoplasm other than BRCA, except for curatively treated non-melanoma skin cancer, in situ carcinoma of the cervix, or other cancer curatively treated and with no evidence of disease for at least five years


  • Receipt of immunotherapy (e.g., interferons; tumor necrosis factor; interleukins; growth factors granulocyte macrophage-colony stimulating factor [GM-CSF], granulocyte-colony stimulating factor [G-CSF], macrophage-colony stimulating factor [M-CSF], or monoclonal antibodies), or chemotherapy, within four weeks (28 days) prior to randomization. Note: Subjects who have received monoclonal antibodies for imaging are eligible.
  • Prior radiotherapy to the site of cancer, if only one site will be used for evaluation of tumor response.

Prior use of bisphosphonates or concurrent use while on study treatment is allowed.

Physiological Function

  • Central nervous system disease or brain metastases, as documented by computed tomography (CT) or magnetic resonance imaging (MRI)
  • Splenectomy

Standard Criteria Need for concurrent treatment with a non-permitted therapy (e.g., concurrent chemotherapy, radiotherapy, systemic immunosuppressive drugs, use of herbal medicines or botanical formulations intended to treat cancer) while on protocol therapy. Palliative radiation to painful bone lesions is allowed.
