Bladder Cancer Clinical Trial
Study of 2141-V11 in People With Non-muscle Invasive Bladder Cancer That Did Not Respond to Standard Treatment
The purpose of this study is to test the safety of the study drug 2141-V11 in people whose NMIBC did not respond to standard treatment, and who will not have the standard surgical procedure to remove the bladder. The researchers will test different doses of 2141-V11 to see which dose is safest in people. The researchers will also do tests to see how the body absorbs, distributes, and gets rid of 2141-V11. This study is one of the first to test 2141-V11 in people, and the first to test 2141-V11 delivered through a catheter into the bladder.
High-grade (HG) NMIBC (HG Ta, CIS, and/or T1) of urothelial histology that is unresponsive to adequate BCG therapy
Stage, grade, and histology must be confirmed by the MSK Department of Pathology
Subjects with tumors of mixed urothelial/non-urothelial histology may be included, but urothelial carcinoma must be the predominant histology; subjects with predominant or exclusively non-urothelial histology are excluded
In those subjects with CIS, the CIS must be present on the tumor sample from the most recent cystoscopy/TURBT
In this context, adequate BCG therapy is defined as at least one of the following:
At least five of six doses of an initial induction course plus at least two of three doses of maintenance therapy
At least five of six doses of an initial induction course plus at least two of six doses of a second induction course
° Disease unresponsive to adequate BCG therapy is defined as:
Persistent or recurrent CIS alone or with recurrent Ta/T1 disease (noninvasive papillary disease/tumor invades the subepithelial connective tissue) within 12 months of completion of adequate BCG therapy
Recurrent HG Ta/T1 disease within 6 months of completion of adequate BCG therapy
HG T1 disease at the first evaluation following an induction BCG course
In subjects with papillary tumors (Ta and T1), a complete TURBT must have been performed, as characterized by:
Attainment of a visually complete resection of all papillary tumors (Ta and T1)
Residual CIS not amenable to complete transurethral resection is acceptable
Receipt of restaging transurethral resection for any tumor with invasion into the lamina propria (HG T1) as part of standard care, with documented presence of uninvolved detrusor muscle
Most recent cystoscopy/TURBT must have been performed within 60 days of the first dose of trial treatment
Absence of urothelial carcinoma involving the upper urinary tract (documented by radiological imaging or ureteroscopy)
Have elected not to undergo or are considered ineligible for radical cystectomy, as determined by the treating surgeon. Reasons for ineligibility or refusal of radical cystectomy should be discussed with the subject as part of the informed consent process. Ineligibility factors for radical cystectomy may include, but are not limited to:
Cardiovascular disease (e.g., recent acute coronary syndrome, arrhythmia, heart failure)
Chronic obstructive pulmonary disease that would preclude a safe surgical procedure, as determined by the treating surgeon
Poor performance status
Prior major abdominal and pelvic surgery that would preclude a safe surgical procedure, as determined by the treating surgeon
In subjects previously treated with pembrolizumab for BCG-unresponsive NMIBC that are found to have disease persistence, the disease persistence must have been confirmed no earlier than 12 weeks after initiation of pembrolizumab; subjects previously treated with pembrolizumab that are found to have disease recurrence or progression from HG Ta and/or CIS to T1 disease prior to 12 weeks after initiation of pembrolizumab may be included after discussion with the Principal Investigator
Age ≥18 years on day of signing informed consent

Absolute neutrophil count (ANC) ≥1000/mm^3 independent of growth factor support
Platelets >75,000/mm^3 without receiving transfusion within 4 weeks prior to screening
Hemoglobin >8 g/dL without receiving transfusion within 4 weeks prior to screening
Creatinine clearance (measured or calculated per institutional standard) >40 mL/min; estimated GFR can also be used in place of creatinine clearance
AST/ALT ≤3 times the institutional upper limit of normal (ULN)
Total bilirubin ≤1.5 times the institutional ULN (except for participants with Gilbert's Syndrome or of non-hepatic origin)
Female subjects of childbearing potential must have a negative serum pregnancy test within 72 hours prior to receiving the first dose of study treatment.
°Female subjects will be considered of non-reproductive potential if any of the following:
Postmenopausal [defined as at least 12 months with no menses without an alternative medical cause; in women <45 years of age a high follicle stimulating hormone (FSH) level in the post-menopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.]
Have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal ligation/occlusion, at least 6 weeks prior to screening
Has a congenital or acquired condition that prevents childbearing
Male and female subjects of childbearing potential must agree, if participating in sexual activity that could lead to pregnancy, to use of an adequate method of contraception from the day of study medication initiation (or 14 days prior to the initiation of study medication for oral contraception) throughout the study period up to 120 days after the last dose of trial therapy. Subjects should be informed that taking the study medication(s) may involve unknown risks to the fetus (unborn baby) if pregnancy were to occur during the study.
Male subjects will be considered of non-reproductive potential if they have azoospermia (whether due to vasectomy or an underlying medical condition). Female subjects will be considered of non-reproductive potential if as described above.
Acceptable methods of contraception:
Single method (one of the following is acceptable): intrauterine device, vasectomy of a female subject's male partner, or contraceptive rod implanted into the skin
Combination method (requires use of two of the following): diaphragm with spermicide (cannot be used in conjunction with cervical cap/spermicide), cervical cap with spermicide (nulliparous women only), contraceptive sponge (nulliparous women only), male condom or female condom (cannot be used together), or hormonal contraceptive [oral contraceptive pill (estrogen/progestin pill or progestin-only pill), contraceptive skin patch, vaginal contraceptive ring, or subcutaneous contraceptive injection]
Male subjects must agree not to donate sperm during and after the study
