Overview
Brief Summary
The purpose of this clinical trial was to demonstrate the benefit of the immunotherapeutic product recMAGE-A3 + AS-15 given to patients with bladder cancer after removal of the bladder. A course of 13 injections was administered over 27 months.
Detailed Description
This study assessed an investigational treatment for patients with Muscle Invasive Bladder Cancer in whom the urinary bladder had been surgically removed. The investigational treatment aimed to increase the body's immune response to a specific antigen expressed by the cancer. The tumour tissue was first tested whether it expressed the MAGE-A3 antigen. The MAGNOLIA study was open to male and female patients with pathologically confirmed muscle invasive transitional cell carcinoma of the urinary bladder with expression of the antigen MAGE-A3 with or without limited lymph node involvement who had no evidence of disease after surgery confirmed with imaging procedures (scans CT/MRI).

Eligibility Criteria
Inclusion Criteria
- •Aged greater than or equal to 18 years at the time ICF is signed, either sex.
- •Histologically confirmed (after cystectomy or if needed transurethral resection) urothelial carcinoma of the bladder which is MAGE-A3 positive.
- •Written informed consent for tissue sampling, the mandatory analyses and for the complete study has been obtained prior to the performance of any other protocol-specific procedure.
- •TNM classification at pathological examination of surgically removed specimen: Stage T2,3 N0 or N1 or N2 and M0 disease or Stage T4 N0 M0 disease.
- •The patient is free of residual disease and free of metastasis, as confirmed by a negative baseline Computer Tomogram (CT scan) or Magnetic Resonance Imaging (MRI) of the pelvis, abdomen and chest no more than 13 weeks prior to randomization. Other examinations should be performed as clinically indicated.
- •Patient is fully recovered from surgery within 13 weeks following cystectomy. For patients who receive adjuvant chemotherapy, the patient is fully recovered within 3-6 weeks following chemotherapy.
- •The patient must have adequate bone-marrow reserve, defined as an absolute neutrophil count 1.0 x 109/L, and a platelet count ≥ 75 x 109/L, adequate renal function, defined as a serum creatinine ≤ 1.5 times the Upper Limit of Normal (ULN), and adequate hepatic function, defined as a Total bilirubin ≤ 1.5 times the ULN, and a Alanine transaminase (ALAT) and Aspartate Transaminase (ASAT) ≤ 2.5 times the ULN as assessed by standard laboratory criteria.
- •World Health Organization (WHO) performance status 0 - 1 at the time of randomization.
- •If the patient is female, she must be of non-childbearing potential, i.e. have a current tubal ligation, hysterectomy, ovariectomy or be post menopausal, or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to administration of study treatment, have a negative pregnancy test and continue such precautions during all study treatment period and for 2 months after completion of the injection series.
- •The patient should be affiliated to health insurance or benefit of such an insurance
Exclusion Criteria
- •The patient has previous or concomitant malignancies at other sites except effectively treated non-melanoma skin cancer, cervical carcinoma in situ, incidental localised prostatic carcinoma or effectively treated malignancy that has been in remission for over 5 years.
- •The patient has received any anti cancer systemic treatment, including immunotherapy (local intravesical BCG is allowed), chemotherapy, except:
- •For the treatment of previous malignancies as allowed by the protocol (i.e., non-melanoma skin cancer, cervical carcinoma in situ, incidental localised prostatic carcinoma or effectively treated malignancy that has been in remission for over 5 years).
- •For the treatment with neo-adjuvant chemotherapy for their muscle invasive bladder cancer
- •For the treatment with adjuvant cisplatinum-based chemotherapy for their muscle invasive bladder cancer
- •The patient has received radiotherapy of the abdominal or pelvic region, within 6 months prior to randomization.
- •Women who are pregnant or breast feeding.
- •The patient has a known infection with human immunodeficiency virus (HIV) or chronic hepatitis B or C.
- •The patient has a history of allergic disease or reactions likely to be exacerbated by any component of the study investigational product.
- •The patient has any confirmed or suspected immunosuppressive or immunodeficient condition or potential immune-mediated diseases as. Patients with vitiligo are not excluded to participate in the trial.
Outcomes
Primary Outcomes
Disease Free Survival
Time Frame: 5 years
To evaluate of the clinical efficacy in terms of Disease Free Survival of treatment versus placebo in the overall population of patients with bladder cancer with MAGE-A3 expression after cystectomy. Disease Free Survival is the time from randomization to either the date of first recurrence of the disease or the date of death (whatever the cause), whichever occurred first. Types of recurrence considered as an event included loco-regional and distant metastases. In addition, any death occurring without prior documentation of tumor recurrence was considered as an event (and was not censored in the statistical analysis) as this approach is less prone to introduce bias.
Secondary Outcomes
- Overall Survival(5 years)
- Distant Metastasis-free Survival(5 years)
- Disease-free Specific Survival(5 years)
