Brief Summary:

The expansion study is a Phase I, multicenter, open label feasibility trial to characterize the pharmacologic activity of IV CPX-POM in bladder tumor tissues obtained from patients with MIBC (Stage ≥T2, N0-N1, M0) who will be scheduled for RC with bilateral (standard or extended) pelvic lymph node dissection (PLND).

The Dose Escalation study was a Phase I, multicenter, open label, dose escalation study to evaluate the DLTs and MTD and to determine the recommended Phase 2 dose (RP2D) of CPX-POM administered IV in patients with any histologically- or cytologically-confirmed solid tumor type and was completed.


Condition or disease Intervention/treatment Phase
Advanced Solid Tumor Drug: CPX-POM Phase 1

Detailed Description:

The expansion cohort of this study will be conducted at up to 3 study sites. It will be an open-label feasibility trial to characterize the pharmacologic activity of IV CPX-POM in bladder tumor tissues obtained from patients with MIBC (Stage ≥T2, N0-N1,M0) who will be scheduled for RC with bilateral (standard or extended) pelvic lymph node dissection (PLND). Approximately half of the patients enrolled will be cisplatin eligible and half will be chemotherapy eligible and scheduled to receive neoadjuvant chemotherapy with gemcitabine + cisplatin. Neoadjuvant treatment with CPX-POM, whether alone or in combination with gemcitabine +cisplatin, will start within 8 weeks of transurethral resection of the bladder tumor (TURBT) that showed muscularis propria invasion.

Approximately 12 patients will be enrolled. Patients who are cisplatin eligible will be treated with two 21-day treatment cycles of CPX-POM (Cycle 1, Days 1-5 treatment, rest days 6-21; Cycle 2, Days 22-26 treatment, rest days 27-43) before a planned RC. Chemotherapy-eligible patients who are scheduled to receive neoadjuvant chemotherapy (gemcitabine + cisplatin in three 21-day treatment cycles) will be treated in addition with three 21-day treatment cycles of CPX-POM (Cycle 1, Days 1-5 treatment, rest days 6-21; Cycle 2, Days 22-26 treatment, rest days 27-42; Cycle 3, Days 43-47, rest days 48-63), i.e. concurrently with the prescribed chemotherapy. The cisplatin + gemcitabine dosing regimen for chemotherapy-eligible patients in the Expansion Cohort will be administered per the institution's standard of care. After each infusion of CPX-POM, patients will remain in the clinic for at least a 1-hour observation period. On Day 1 of Cycle 1, single blood and clean catch urine samples will be collected prior to the first CPX-POM infusion.

Primary Outcome Measures :
  1. determine disease response following 2 or 3 CPX-POM treatment cycles by assessing the complete and partial pathologic response rate at the time of radical cystectomy (RC) [ Time Frame: 56 days ]
    Tumors will be assessed in a standard manner and given grade/stage according to the American Joint Commission on Cancer (AJCC) criteria. Efficacy will be assessed based on pathologic criteria and evidence of pharmacologic activity in the target tissue.


Secondary Outcome Measures :
  1. Number of Participant with any Serious Adverse Events (SAEs) as assessed by Common Terminology Criteria for Adverse Events (CTCAE version 4.03) [ Time Frame: 56 days ]
    Incidence of Serious Adverse Events in subjects receiving CPX-POM.

  2. Number of Participant with any Adverse Events (AEs) as assessed by Common Terminology Criteria for Adverse Events (CTCAE version 4.03) [ Time Frame: 56 days ]
    Incidence of Adverse Events in subjects receiving CPX-POM.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

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 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).
  4. Patient has a predicted life expectancy of ≥3 months.
  5. Patient has a GFR of ≥30 mL/min/1.73 m^2.
  6. Patient has adequate hepatic function, as evidenced by a total bilirubin ≤1.5 × ULN, aspartate transaminase (AST), and /or alanine transaminase (ALT) ≤3 × ULN or ≤5 ×ULN, if due to liver involvement by tumor.
  7. 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.
  8. Patient has no significant ischemic heart disease or myocardial infarction (MI) 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 (QTc) <470 msec by Fridericia (QTcF). 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.
  9. 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.
  10. Patient is willing and able to participate in the study and comply with all study requirements.
  11. Patients must have histologically confirmed MIBC (≥T2, N0-N1, M0 per AJCC) pure or mixed histology urothelial carcinoma. Clinical node-positive (N1) patients are eligible provided the lymph nodes (LNs) are confined to the true pelvis and are within the planned surgical LN dissection template.
