Newly diagnosed or recurrent bladder tumors
Brief summary
This is a phase II, single center open label to determine safety, dose tolerance, PK and PD of the recommended Phase 2 dose (RP2D) of CPX-POM administered in patients with any newly diagnosed or recurrent bladder tumors.
Detailed description
This will be an open-label study to determine the safety, dose tolerance, pharmacokinetics, and pharmacodynamics of CPX-POM in patients with newly diagnosed or recurrent, untreated or intravesical treatment completed \>6 months before the current diagnosis, resectable tumors. Approximately 12 patients will be enrolled and treated with 900 mg/m2 CPX-POM administered IV over 20 minutes once per day for 5 days followed by TURBT on Day 5 after the fifth dose. TURBT will be performed 2 to 6 hours following drug administration on Day 5. Pretreatment bladder tumor tissues will be obtained at the time of in-office cystoscopy by cold cup biopsy within 4 weeks of TURBT. Posttreatment bladder tumor tissues will be obtained at TURBT. Bladder tumor tissues will undergo pathological evaluation at each site. Prior to administration of the first CPX-POM dose on Day 1, pre-dose blood (plasma) and urine (clean catch) samples will be collected. At the time of TURBT on Day 5, one 3-mL blood (plasma) sample and a urine specimen will be collected for measurement of CPX-POM concentrations. Patients will be followed for at least 30 days after the last dose of CPX-POM for safety

Eligibility
Inclusion criteria
1. Patient is male or female aged ≥18 years. 2. Patient provided signed and dated informed consent prior to initiation of any study procedures. 3. Patient is likely to have a new bladder tumor based on clinical presentation or is at high risk for tumor recurrence based on previous history. 4. Patient has a cystoscopically confirmed bladder tumor and will be scheduled to undergo TURBT. 5. Patient has not received prior treatment for bladder cancer or completed their last intravesical therapy \>6 months before screening. 6. Patient has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 (fully active, able to carry out all pre-disease activities without restriction) or 1 (unable to perform physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature). 7. Patient has a predicted life expectancy of ≥3 months. 8. Patient has adequate renal function (creatinine ≤1.5 × the upper limit of the normal range (ULN) or an estimated glomerular filtration rate (eGFR) of \>30 mL/min/1.73 m2). 9. Patient has adequate hepatic function, as evidenced by a total bilirubin ≤1.5 × ULN, aspartate aminotransferase (AST) ≤3 × ULN and /or alanine aminotransferase (ALT) ≤3 × ULN. 10. Patient has adequate bone marrow function, as evidenced by hemoglobin ≥9.0 g/dL in the absence of transfusion within the previous 72 hours, platelet count ≥100×10\^9cells/L, and absolute neutrophil count (ANC) ≥1.5×10\^9 cells/L. 11. Patient has no significant ischemic heart disease or myocardial infarction within 6 months before the first dose of CPX-POM and currently has adequate cardiac function, as evidenced by a left ventricular ejection fraction of \>50% as assessed by multi-gated acquisition (MUGA) or ultrasound/echocardiography (ECHO); and corrected QT interval by Fridericia's correction formula (QTcF) \<450 msec for males and \<470 msec for females. The eligibility of patients with ventricular pacemakers for whom the QT interval may not be accurately measurable will be determined on a case-by-case basis by the Sponsor in consultation with the Medical Monitor. 12. Patient and his/her partner agree to use adequate contraception after providing written informed consent through 3 months after the last dose of CPX-POM, as follows: 1. For women: Negative pregnancy test during Screening and at Day 1 of each treatment cycle and compliant with a medically-approved contraceptive regimen during and for 3 months after the treatment period or documented to be surgically sterile or postmenopausal. 2. For men: Compliant with a medically-approved contraceptive regimen during and for 3 months after the treatment period or documented to be surgically sterile. Men whose sexual partners are of child-bearing potential must agree to use 2 methods of contraception prior to study entry, during the study, and for 3 months after the treatment period. 13. Patient is willing and able to participate in the study and comply with all study requirements.

Evaluate the Dose Limiting Toxicities (DLTs) of CPX-POM
A DLT will include some Grade 3 or 4 AEs if deemed related to study drug. In addition, any patient who is unable to receive 80% of the expected dose of CPX-POM (i.e., patients who are unable to receive at least 4 of the 5 scheduled doses) because of AEs will be considered to have a DLT.
