Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators intend to evaluate the safety and toxicity proﬁle of intravesically administered multidrug regimen of Cabazitaxel, Cisplatin and Gemcitabine in treatment refractory Transitional Cell Carcinoma.The investigators propose to conduct a combined phase I trial to assess the safety, toxicity, and efﬁcacy of a novel multidrug intravesical regimen consisting of Cabazitaxel, Gemcitabine, and Cisplatin (CGC) in the treatment of BCG resistant non-muscle invasive urothelial carcinoma of the bladder. This phase I trial will have a combined dose and cycle-escalation scheme with enrollment of up to 24 patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Nonsurgical treatment strategies for BCG refractory bladder cancer have failed to prove themselves as reliable options for increased survival among this subset of bladder cancer patients. For these patients, removal of the bladder with all the associated perioperative risks and the subsequent reduction of quality of life, remains the only option. Prior attempts at second line treatments have included intravesical (within the bladder) monotherapy with a range of drugs including Gemcitabine and Paclitaxel (a taxane, similar to Cabazitaxel). These drugs have shown some potential improvement for a small number of patients Given the synergy of systemic chemotherapy, it is believed that a multidrug regimen would allow for further improvement in survival among these patients.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Patients must have a histologically confirmed diagnosis of non- muscle invasive urothelial carcinoma of the bladder at the study institution prior to the beginning of the study. This includes patients with:

* High grade Ta papillary lesion(s)
* High or low grade T1 papillary lesion(s)
* Carcinoma In Situ (CIS), with or without Ta or T1 papillary tumor(s) of any grade The patient must have Bacillus Calmette-Guerin (BCG) refractory or recurrent non-muscle invasive bladder cancer
* Refractory disease is defined as evidence of persistent high risk bladder cancer (high grade Ta, T1 and/or CIS) at the first cystoscopic exam after the initial 6 week induction course of BCG or at the 6 month cystoscopic exam.
* Recurrent disease is defined as reappearance of disease after achieving a tumor- free status by 6 months following a full induction course of BCG with or without maintenance BCG. Participants must have recurred within 18 months following the last dose of BCG.

* Low-grade superficial (Ta) disease will not be considered recurrent.
* Patients must exhibit disease recurrence after receiving some form of standard intravesical therapy that must include a minimum of one induction course of BCG and may also include prior exposure to mitomycin, interferon, single agent gemcitabine or taxane therapy or maintenance.
* Patients must be eligible for radical cystectomy and refuse this standard of care treatment or not be a surgical candidate for radical cystectomy based on other comorbidities.
* All grossly visible disease in the bladder must be fully resected and pathologic stage will be confirmed at the study institution.
* Patients enrolled in other clinical trials must have received their last treatment at least 6 weeks prior to enrollment.
* Age \> 18 and must be able to read, understand and sign informed consent
* Patients must have an Eastern Cooperative Oncology Group (ECOG) performance Status: ECOG of 0 or 1 including patients who are not surgical candidates due to comorbid conditions.
* Women of childbearing potential must have a negative pregnancy test.
* All patients of childbearing potential must be willing to consent to using effective contraception, i.e., intrauterine device (IUD), Birth control pills, Depo-Provera, and condoms while on treatment and for 3 months after their participation in the study ends.
* No experimental intravesical therapy within 6 weeks of study entry

Exclusion Criteria

* History of severe hypersensitivity reaction (≥grade 3) to docetaxel
* History of severe hypersensitivity reaction (≥grade 3) to polysorbate 80 containing drugs
* Concurrent or planned treatment with strong inhibitors or strong inducers of cytochrome P450 3A4/5 (a one week wash-out period is necessary for patients who are already on I these treatments)

* Concurrent treatment with any systemic chemotherapeutic agent.
* Inadequate organ and bone marrow function as evidenced by:

* Hemoglobin: less than 8.0 g/dL
* Absolute neutrophil count: less than 1.5 x 10\^9/L
* Platelet count: less than 80x 10\^9/L

* Total bilirubin \>1.5 x ULN
* Serum creatinine \>2 x ULN. If creatinine 1.5 - 2.0 x ULN, creatinine clearance will be calculated according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula and patients with creatinine clearance \<30 mL/min should be excluded.
* Women who are pregnant or lactating.
* Documented history of vesicoureteral reflux or an indwelling urinary stent.
* Participation in any other research protocol involving administration of an investigational agent within 6 weeks prior to study entry.
