A Phase 3 Single-arm Study of UGN-104 for the Treatment of Low-grade Upper Tract Urothelial Cancer

Korábbi kezelés

• Patient is actively being treated or intends to be treated with systemic chemotherapy during the duration of the study.
• Patient is currently receiving any other investigational product, has participated in a research protocol involving administration of an investigational product in the past 30 days, or plans to participate in a research protocol involving administration of an investigational product during study conduct.
• Patient was previously treated with JELMYTO (product code UGN-101) for UTUC.

Más betegség

• UC specific exclusions:
  • Patient received Bacillus Calmette-Guérin (BCG) treatment for UC during the 6 months before enrollment.
  • The patient has untreated concurrent UC in locations other than the target area (unless treated and resolved during Screening); ie, ureteral and lower urinary tract tumors must be completely ablated before entry.
  • Patient has a history of carcinoma in situ (CIS) in the urinary tract.
  • Patient has a history of invasive UC in the past 5 years.
  • Patient has a history of HG papillary UC in the urinary tract in the past 2 years.
• Any other malignancy diagnosed within 2 years before enrollment with the exception of:
  • Basal or squamous cell skin cancers.
  • Noninvasive cancer of the cervix.
  • Any other cancer deemed to be of low risk for progression or patient morbidity during the study period in the opinion of the investigator.
• Known allergy or sensitivity to any component of the study treatment (including excipients) that in the investigator's opinion cannot be readily managed.
• Patient has an intractable bleeding disorder (eg, coagulation factors deficiencies, Von Willebrand disease).
• Patient has any other medical or mental condition(s) that make(s) his/her participation in the study unadvisable in the opinion of the investigator.

Laborértékek

• Women who are pregnant (positive urine or serum pregnancy test), planning to become pregnant during the study period, or who are breastfeeding are not eligible to enroll.

Egyéb

• Patient with urinary obstruction such that there is an inability to deliver the study treatment to the pyelocalyceal system either via ureteral catheter (retrograde administration) or nephrostomy tube (antegrade administration).
• Where applicable per country regulation, the patient must not be currently committed to an institution by virtue of an order issued by either judicial or administrative authorities.

• Provide written informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form and protocol.
• Naive or recurrent patients with LG, non-invasive UTUC in the pyelocalyceal system, with the following disease characteristics:
  • At least 1 measurable papillary LG tumor, evaluated visually, ≤ 15 mm. The largest lesion should not exceed 15 mm. Debulking to ≤ 15 mm is permitted.
  • Biopsy taken from at least 1 tumor located above the ureteropelvic junction revealing LG urothelial carcinoma (UC). Patients who have been biopsied within 8 weeks before Screening for this study and shown to have LG UC may have these historical biopsies used for enrollment into the study and do not require repeat biopsy during Screening.
  • Patient should have at least 1 remaining papillary LG tumor evaluated visually with a diameter of at least 5 mm post-biopsy.
  • Wash urine cytology sampled from the pyelocalyceal system documenting the absence of high-grade (HG) UC, diagnosed not more than 8 weeks before Screening.
  • Patients with bilateral LG-UTUC may be enrolled if at least 1 side meets the inclusion criteria for the study and if the other kidney does not require further treatments. (The disease in the other kidney must be completely ablated before receiving treatment in the study.) Note: If both upper tracts meet inclusion criteria, the treating urologist in consultation with the sponsor's medical monitor can decide which side to treat in the study. The pyelocalyceal system not under study must be free of cancer before the first instillation on the side to be treated in the study.
• Patients with Eastern Cooperative Oncology Group (ECOG) performance status < 3 (with Karnofsky > 40).
• Patients with life expectancy > 24 months at time of Screening.
• Patients must have adequate organ and bone marrow function as determined by the following routine laboratory tests:
  • Leukocytes ≥ 3,000/μL (≥ 3 × 10\^9/L).
  • Absolute neutrophil count ≥ 1,500/μL (≥ 1.5 × 10\^9/L).
  • Platelets ≥ 100,000/μL (≥ 100 × 10\^9/L).
  • Hemoglobin ≥ 9.0 g/dL.
  • Total bilirubin ≤ 1.5 × upper limit of normal (ULN).
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN.
  • Alkaline phosphatase ≤ 2.5 × ULN.
  • Estimated glomerular filtration rate (eGFR) ≥ 30 mL/min.
• Patient has no active urinary tract infection (UTI) as confirmed by urine culture or urinalysis. Note: In case of a symptomatic UTI the patient will be treated with antibiotics and the instillation will be postponed until resolution. In the case of asymptomatic bacteriuria, the use of prophylactic antibiotics and postponement of treatment is at the discretion of the investigator.
• Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for clinical study participants.
  • Female patients of childbearing potential (defined as premenopausal women who have not been sterilized) and male patients with female partners of childbearing potential must agree to use 2 acceptable forms of effective contraception from enrollment through 6 months post treatment. Sexually active male patients must agree to use a condom during intercourse for at least 48 hours after each instillation.
  • Acceptable methods of birth control considered to have a low failure rate (ie, less than 1% per year) when used consistently and correctly include implants, injectable, combined (estrogen/progesterone) oral contraceptives, intrauterine devices (only hormonal), condoms with spermicide, sexual abstinence* or vasectomized partner.
• Sexual abstinence is defined as refraining from intercourse from enrollment through 6 months post treatment. Periodic abstinence (calendar, symptothermal, post-ovulation methods) is NOT an acceptable method of contraception.
