Bladder Cancer Clinical Trial

A Phase 1 Study of Intravesical VAX014 for Instillation in Subjects With Non-Muscle Invasive Bladder Cancer

Summary

The purpose of this research study is to evaluate the safety, tolerability and activity of VAX014 for Instillation (VAX014) in patients with low-grade Non-Muscle Invasive Bladder Cancer (NMIBC). VAX014 is a targeted oncolytic agent designed to kill tumor cells following instillation into the urinary bladder.

Full Description

This study will evaluate the safety and tolerability of VAX014 using a 3+3 dose escalation design to determine a maximum tolerated dose (MTD) followed by a dose expansion at the Recommended Phase 2 Dose (RP2D). Both phases of the study will use a Window of Opportunity study design where patients with a single, low-grade Ta lesion will receive VAX014 via a urinary catheter into the bladder, weekly for 6 weeks prior to undergoing Transurethral Resection of Bladder Tumor (TURBT) to assess antitumor activity against the mapped lesion.

Patients enrolled in this study must have low-grade (Ta) Non-Muscle Invasive Bladder Cancer. However, eligible patients may have up to 5 low-grade Ta lesions at screening, and all but a single mapped lesion will be resected prior to receiving VAX014. The mapped lesion is assessed for anti-tumor activity.

VAX014 is a formulation of recombinant bacterial minicells which is designed to selectively target two NMIBC-associated integrin heterodimers to de-stabilize tumor cell membranes, with the result being tumor cell lysis.

Eligibility Criteria

Inclusion Criteria:

Signed, informed consent
Age 18 or more years
Pathologically confirmed low-grade Ta urothelial carcinoma (UC) of the urinary bladder
NMIBC with one solitary measurable tumor at the start of study, measuring ≥ 5 mm and ≤ 15 mm in greatest diameter (up to 4 additional low-grade Ta lesions, each measuring no more than 15 mm may be removed at screening provided a single lesion remains)
Treatment-naïve or failed one previous regimen of intravesical therapy (BCG or chemotherapy)
If recurrent disease, then more than 6 months from prior resection, more than 3 months from completion of last intravesical therapy with BCG, and more than 6 weeks from completion of last therapeutic intravesical therapy with chemotherapy
If previously treated, recovered from prior treatment-related toxicity to ≤ Grade 1
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 116
Absolute neutrophil count (ANC) ≥ 1,500/mm3
Platelet count ≥ 100,000/mm3
Total bilirubin ≤ 1.5 x upper limit of normal (ULN), or ≤ 3 x ULN in subjects with Gilberts disease
Serum creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 30 mL/min
Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) ≤ 2.5 x ULN
Willingness to participate in collection of pharmacokinetic samples
Women of childbearing potential must have a negative serum pregnancy test.
All subjects of childbearing potential must be willing to use effective contraception while on treatment and for 3 months after the last dose of VAX014

Exclusion Criteria:

Additional papillary disease at screening (in addition to the solitary low-grade Ta lesion detailed in the inclusion criteria) that

Consist of 6 or more lesions
Consists of any lesion with a maximal diameter of greater than 15 mm
Confirmed or suspected perforated bladder
History of difficult catheterization that in the opinion of the investigator will prevent administration of VAX014
Presence or history of any high-grade urothelial cancer (including CIS) or high-grade urine cytology
Intravesical chemo-or biological therapy within 6 months of first administration of VAX014
UC of the ureters or urethra
History of interstitial cystitis
History of radiation to the pelvis
History of vesicoureteral reflux or an indwelling urinary stent
Other known active cancer(s) likely to require treatment or interfere with study objectives over the next two (2) years
Active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy
Known HIV, Hepatitis B, or Hepatitis C infection
Significant cardiovascular risk (e.g., coronary stenting within 8 weeks, myocardial infarction within 6 months)
Major surgery other than diagnostic surgery within 4 weeks of first administration of VAX014
Pregnant or currently breast-feeding
Psychiatric illness/social situations that would interfere with compliance with study requirements
Presence of any sessile appearing tumor suspected of being invasive or high-grade
