Inclusion Criteria

1. Willing and able to freely provide written informed consent (in presence of an Independent Witness if applicable) prior to performing study procedures., 10. Able and willing to comply with the scheduled visits, therapy plans, and laboratory tests required in this protocol., 2. Age 18 years or older, male or female., 3. Persistent or recurrent CIS of the bladder histologically confirmed, with or without concomitant recurrent HG Ta-T1 and with no evidence of metastases demonstrated by abdominal CT scan or MRI., 4. BCG unresponsive patients who refuse or are unfit for radical cystectomy. BCG-unresponsive disease is defined as persistent or recurrent CIS alone or with recurrent HG Ta-T1 disease within 12 months of completion of adequate BCG therapy. Adequate BCG therapy is defined as at least one of the following: 1) At least five of six doses of an initial induction course plus at least two of three doses of maintenance therapy. 2) At least five of six doses of an initial induction course plus at least two of six doses of a second induction course., 5. Complete resection of Ta-T1 papillary lesions before entering the trial in patients with concomitant CIS and papillary tumors (residual CIS acceptable, obvious areas of CIS should also be fulgurated). a. In patients with T1 papillary lesions undergoing resection of the base of the lesion, the biopsy should contain muscle fibers. b. In patients undergoing transurethral resection of their bladder tumors, absence of locally advanced disease should be confirmed by pelvic examination under anesthesia., 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2., 7. Adequate organ function: absolute neutrophil count = 1,500/mm3, platelets = 100,000/mm3, hemoglobin = 10.0 g/dL, ALT/AST = 1.5 x upper limit of normal (ULN), alkaline phosphatase = 5 x ULN, total serum bilirubin = 1.5 x ULN, serum creatinine = 2.2 mg/dL., 8. Women in non-reproductive years (defined as surgically sterile or one year postmenopausal). Women of childbearing potential (WOCBP) must have a negative serum pregnancy test upon entry into this study and agree to use highly effective contraceptive methods, i.e. methods that can achieve a failure rate of less than 1% per year when used consistently and correctly. Such methods include: • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: - oral - intravaginal - transdermal • progestogen-only hormonal contraception associated with inhibition of ovulation: - oral - injectable - implantable • intrauterine device (IUD) • intrauterine hormone-releasing system ( IUS) • bilateral tubal occlusion • vasectomised partner (*) • sexual abstinence (**) (*) Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual partner of the WOCBP trial participant and that the vasectomised partner has received medical assessment of the surgical success. (**) Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated to the study treatment. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject., 9. Male patients with WOCBP partners must agree to use effective contraceptive methods, i.e.: • condom • consider contraception for non-pregnant WOCBP partner.

Exclusion Criteria

1. Current or previous muscle-invasive disease (T2-T4) or metastatic urothelial carcinoma., 10. Presence of significant urologic disease interfering with intravesical therapy., 11. Current enrollment or participation in another therapeutic clinical trial within 6 months preceding screening. Patients previously included in a BCG-only study arm might be enrolled following discussion with the medical monitor and/or sponsor if the definition of adequate BCG therapy is met., 12. Known substance and/or alcohol abuse., 13. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for entry in this study or could compromise protocol objectives., 14. Pregnancy, lactating women or women of childbearing potential (WOCBP) unwilling to use adequate birth control measures for the duration of the study and until 6 months after the end of treatment., 15. Male patients with WOCBP partners unwilling to use contraceptive methods for the duration of the study and until 6 months after the end of treatment., 16. Subjects who have a mean QTc >480 msec at baseline and who need concomitant medications which may cause QT prolongation., 17. Applies to France only: Persons deprived of liberty by judicial or administrative decision, adults subject to a legal protection measure (under guardianship/curators), persons under protective measures and persons not affiliated with social security will be excluded from the study., 2. Suspected hypersensitivity to paclitaxel or to any of the ONCOFID-P-B constituents., 3. Previous or concomitant cancer of the upper urinary tract or the prostatic urethra. Freedom from upper tract disease must be demonstrated by intravenous pyelogram, retrograde pyelogram, CT scan or MRI., 4. Current or prior systemic therapy for bladder cancer., 5. Intravesical therapy within 4 weeks prior to beginning study treatment with the exception of cytotoxic agents (e.g. mitomycin C, doxorubicin and epirubicin) when administered as a single instillation immediately following a TURBT procedure between 14 to 60 days prior to beginning study treatment., 6. Symptomatic urinary tract infection or bacterial cystitis. Once successfully treated (negative urine culture), patients may enter the study., 7. Major surgery, other than diagnostic, within 4 weeks prior to treatment., 8. Previous (within the last 5 years) or current malignancies at other sites, except for adequately treated basal cell, squamous cell skin cancer, in situ carcinoma of the cervix or prostate cancer on active surveillance at low risk for progression, defined as prostate-specific antigen (PSA) <10 ng/dL, Gleason score 6 or less and cT1., 9. Subjects who, in the opinion of the Investigator, cannot tolerate intravesical administration or intravesical surgical manipulation (cystoscopy, biopsy) due to the presence of serious comorbid condition(s) (e.g., uncontrolled cardiac or respiratory disorders).
