Therapeutic Instillation of Mistletoe
キーワード
概要
説明
This is a randomized, open-label, active-controlled, prospective, multinational Phase III confirmative study with 2 treatment groups and an adaptive design (Bauer and Köhne, 1994). The study is designed to compare the efficacy of treatment with abnobaVISCUM® 900 with Mitomycin C (MMC). Patients with completely resected superficial bladder carcinoma (Stage Ta) with an intermediate risk classification according to the European Association of Urology (EAU, update 2013) and with one immediately post operative MMC 40 mg intravesical instillation will be eligible for inclusion in the study.
The study comprises a screening period of not more than 6 weeks, a treatment period of 12 months for abnobaVISCUM® 900 and MMC and a follow-up period of 12 months. Patients will be screened within 6 weeks after the transurethral resection of the bladder (TURB) and the immediately post operative MMC 40 mg intravesical instillation. A re-resection should be performed before inclusion if indicated. Every patient is to provide written informed consent before any study related procedures will be performed.

| 基準 | Inclusion Criteria: - Signed and dated written informed consent for data protection and willingness to participate and comply with the study protocol prior to any study-related procedures - Completely resected (detrusor muscle in the TUR specimen according to need) superficial bladder carcinoma (Stage Ta) with classification as intermediate-risk according to the EAU (update 2013) and one immediately post operative intravesical MMC instillation of 40 mg, completed re-resection if indicated - Karnofsky Performance Status of 50% to 100% (corresponding to Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2) - Life expectancy of ≥ 2 years at the time point of study inclusion - Normal renal and liver function, normal cardiac and hematology profiles (patients with laboratory values slightly outside the reference range may be included, unless the investigator considers the abnormality as clinically significant) - Female patients of childbearing potential must have a negative pregnancy test (β-human chorionic gonadotropin test) at Screening. Pregnancy during the treatment period including 12 weeks after the last instillation has to be excluded Exclusion Criteria: - Locally infiltrative or metastatic bladder tumor (Stage T2 or greater), low-risk Ta tumor (primary, solitary, LG/G1, <3 cm, no CIS) or high-risk tumors according to EAU classification, update 2013 (T1; HG/G3; CIS; multiple and recurrent and large [>3 cm] Ta G1/G2 tumors [all conditions must be present at this point], presence of upper urinary tract tumors or lesions which were not completely removed by TURB - Urinary tract infection, benign prostatic obstruction grade II or III, neurogenic bladder, stress incontinence, bladder or urethral diverticula, fistulas or urethral stenosis - Patients with acute systemic illness, such as inflammatory infections with fever > 38°C - Patients with previous recurrence of a superficial bladder cancer or radiotherapy of the bladder or other intravesical treatment within the last 6 months, or patients with previous mistletoe therapy - Patients with other previous or co-existing malignancies or CIS - Patients having any previous or concurrent therapy with a systemic chemo- / immunotherapeutical treatment regimen, in particular vinca alkaloids, bleomycine and doxorubicine, or patients who are treated with pyroxidine hydrochloride (vitamin B6) - Untreated coagulation disorders or inadequate anticoagulation therapy - Leukocyte count < 4,000/mm3 or platelet count < 100,000/mm3 - Serum creatinine > 1.7 mg/dL - Patients with known hypersensitivity to the excipients of the study medication (monosodium phosphate, disodium phosphate, ascorbic acid) - Patients with a known hypersensitivity to mistletoe products and MMC - Patients who were administered within a 4-week period before Visit 1 any other experimental drug under investigation - Male patients planning to father a child or sperm donation from the first administration of study medication until 3 months after the last administration of the study medication - Male patients unwilling to use barrier contraception ie, condoms and spermicide, from the day of first administration of the study medication until 12 weeks after administration of the study medication.
