Study of Bacillus Calmette-Guerin (BCG) Combined With PANVAC Versus BCG Alone in Adults With High Grade Non-Muscle Invasive Bladder Cancer Who Failed At Least 1 Course of BCG

This is an interventional treatment trial for Bladder Cancer focused on measuring Urothelial Carcinoma, Vaccines, Immunotherapy, TICE BCG, Intravesical Treatment Read More

• INCLUSION CRITERIA:

3.1.1.1 Patients must have histologically confirmed localized high grade (G3) transitional cell carcinoma (urothelial carcinoma) of the bladder that is stage Ta, T1, and/or carcinoma in-situ (CIS) confirmed by the Laboratory of Pathology, National Cancer Institute (NCI) 45 days prior to study entry. This can be obtained at an outside hospital prior to entry into the study or at the NCI. However, all outside pathology specimens will require that the formalin-fixed paraffin embedded tissues be re-read by the Laboratory of Pathology, NCI. For patients enrolled at collaborating trial sites, diagnosis must be confirmed by the Department of Pathology at the institution where the patient is enrolled on the trial.

Pathology can also be reviewed by the Laboratory of Pathology at the NCI if the participating trial site prefers another pathologic evaluation.

3.1.1.2 Patients have failed at least one previous induction course of intravesical Bacillus Calmette-Guerin (BCG), defined as histologically confirmed persistent or relapsing tumor present on post-BCG endoscopic evaluation. All BCG failures will be considered for inclusion into the study, including BCG-refractory, -resistant, and relapsing, as defined in the Rationale and Background. For the purposes of the study, BCG-refractory and BCG-resistant subjects will be considered to have BCG-persistent disease.

3.1.1.3 Patients who are not currently candidates for radical cystectomy (e.g. patient refuses surgery, comorbidities preclude major surgery, etc.).

3.1.1.4 Age >18 years.

--Because no dosing or adverse event data are currently available on the use of BCG in combination with PANVAC in patients <18 years of age, children are excluded from this study.

3.1.1.5 Eastern Cooperative Oncology Group (ECOG) performance status <2.

3.1.1.6 Patients must have normal organ and marrow function as defined below:

• absolute neutrophil count greater than or equal to1,500/mcL
• platelets greater than or equal to 50,000/mcL
• total bilirubin less than or equal to 1.5 X institutional upper limit of normal
• Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase (SGOT)/alanine aminotransferase (ALT)(serum glutamic pyruvic transaminase (SGPT) less than or equal to 3 X institutional upper limit of normal
• estimated glomerular filtration rate (GFR) (calculated using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation) greater than or equal to 30 mL/min/1.73 sq.m.

3.1.1.7 Computerized Tomography (CT) urogram or Magnetic Resonance Imaging (MRI) urogram. If urogram protocol not available or contrast allergy/poor renal function preclude such imaging, then noncontrast CT or MRI of the abdomen/pelvis within 45 days of study entry will suffice.

3.1.1.8 Chest x-ray negative for metastatic disease.

3.1.1.9 Ability of patient to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

3.1.2.1 Previous pelvic radiation for bladder or prostate cancer if performed <12 months prior to enrollment into the study.

3.1.2.2 Patients who are receiving any other concurrent investigational agents (patients are eligible to enroll 4 weeks after completion of prior agent).

3.1.2.3 Patients who have had chemotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. There will be at least a 3 week delay from the time of a previous bladder biopsy/transurethral resection of bladder tumor (TURBT) to allow for adequate bladder healing prior to enrollment.

3.1.2.4 Patients with a history of encephalitis, multiple sclerosis, or seizures within the last year (from seizure disorder or brain metastasis) should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.

3.1.2.5 History of allergy or untoward reaction to prior vaccination with vaccinia virus

3.1.2.6 Patients should have no evidence of being immunocompromised as listed below:

• Human immunodeficiency virus positivity due to the potential for decreased tolerance and risk for severe side effects
• Active autoimmune diseases requiring treatment or a history of autoimmune disease that might be stimulated by vaccine treatment. This requirement is due to the potential risks of exacerbating autoimmunity. Patients with endocrine disease that is controlled by replacement therapy including thyroid disease and adrenal disease and vitiligo may be enrolled.
• History of splenectomy

3.1.2.7 Uncontrolled intercurrent illness which would interfere with the ability of the patient to carry out the treatment program, including, but not limited to, active second malignancy other than a cancer that has been successfully treated resulting in a high likelihood of long-term survival (e.g. completely resected basal cell or squamous cell carcinoma of the skin, stage 1 renal cell carcinoma treated with partial nephrectomy, treated low risk prostate cancer, etc.), inflammatory bowel disease (e.g. Crohn's disease or ulcerative colitis), active diverticulitis, 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.

3.1.2.8 Pregnant women are excluded from this study because the vaccines used in the study may have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the vaccine, breastfeeding should be discontinued if the mother is treated with vaccines. These potential risks may also apply to other agents used in this study. Patients must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while her partner is participating in this study, she should inform her treating physician immediately

3.1.2.9 Concurrent use of systemic steroids, except for physiologic doses of systemic steroids for replacement or local (topical, nasal, or inhaled) steroid use. Limited doses of systemic steroids to prevent intravenous (IV) contrast, allergic reaction, or anaphylaxis (in patients who have known contrast allergies) are allowed. Although topical steroids are allowed, steroid eye-drops are contraindicated

3.1.2.10 Altered immune function, including immunodeficiency or history of immunodeficiency; eczema; history of eczema, or other eczematoid skin disorders; or those with acute, chronic or exfoliative skin conditions (e.g. atopic dermatitis, burns, impetigo, varicella zoster, severe acne, or other open rashes or wounds). There is an increased risk to patients or contacts with eczema, atopic dermatis, and other immune deficiencies who are at risk for eczema vaccination.

3.1.2.11 Medical conditions which, in the opinion of the investigators, would jeopardize the patient or the integrity of the data obtained

3.1.2.12 Serious hypersensitivity reaction to egg products

3.1.2.13 Chronic hepatitis infection, including B and C, because of potential immune impairment

3.1.2.14 Clinically significant cardiomyopathy or cardiac complications, including recent myocardial infarction or cerebrovascular accident within one year, and/or unstable or uncontrolled angina

3.1.2.15 Previous intolerance to BCG intravesical therapy suggested by development of systemic BCG infection in the past and/or grade 4 or greater adverse effect by Common Terminology Criteria in Adverse Events (CTCAE) v4.0.

3.1.2.16 Patients unable to avoid close contact or household contact with the following high-risk individuals for three weeks after the Day 1 vaccination: (a) children less than or equal to 3 years of age, (b) pregnant or nursing women, (c) individuals with prior or concurrent extensive eczema or other eczematoid skin disorders, or (d) immunocompromised individuals, such as those with human immunodeficiency virus (HIV).

3.1.3 Inclusion of Women and Minorities:

Both men and women of all races and ethnic groups are eligible for this trial.
