Study Overview
Brief Summary
To determine the efficacy of oral APL-1202 administered consecutively for 12 weeks in subjects with high-risk NMIBC relapsed from intravesical chemo/BCG therapy based on the recurrence-free rate (RFR) at 12 months after APL-1202 treatment.
Detailed Description
This trial was a single-arm, open-label, multi-center clinical study consisting of two periods: the dose-escalation and treatment period, and the follow-up and maintenance period.
Dose-Escalation and Treatment Period APL-1202 was orally administered TID daily and continuously for 12 weeks. APL-1202 dose was increased from daily 300, 450, 600 to 750mg or maximum tolerated dose (MTD).
A modified 3+3 design was employed: The dose was started at 300 mg and increased to 450 mg, 600 mg and 750 mg if there was no dose-limiting toxicity (DLT) in 3 subjects after 4-week consecutive administration of APL-1202. When the dose-escalation study was in progress, the doses for any newly enrolled subjects would be the starting dose or the highest dose confirmed with no DLT by the dose-escalation cohort at the time of enrollment. When the MTD or the 750 mg daily dose was attained as a safe dose, the dose for all subjects in the study or subsequently enrolled subjects would be MTD or 750 mg/day.
Follow-up and Maintenance Period APL-1202 was orally administered at the highest safe dose proven by the dose-escalation cohort, continuously for 3 months; This period was 12 months. To fit the 3-month cystoscopy follow-up schedule, the maintenance therapy, starting from 3-month off, was given continuously every other 3 months, resulting in 6 months of dosing in total.

Inclusion Criteria
- •Well-informed with this trial and willing to sign the informed consent form;
- •Subjects have been clinically and histologically proven as relapsed high-risk non-muscle-invasive urothelial carcinoma of the bladder through clinical cystoscopy, urine cytology and pathological examination within 28 days before the enrollment; Subjects who met the high-risk definition in EAU Guidelines on Non-Muscle-Invasive Bladder Cancer (2012 Edition), including those who met the high-risk definition in current or any previous recurrence or primary diseases; Papillary carcinomas may or may not include Cis; All papillary carcinoma subjects with no visible tumor after transurethral resection of bladder tumor (TURBT); May include Cis subjects with visible tumors remaining after TURBT;
- •Past treatment history:
- •Chemo-relapsed subgroup: the subjects who should have had intravesical chemotherapy in the 3 years prior to enrollment, but could not undergo any BCG therapy; BCG-relapsed subgroup: the subjects who should have had intravesical BCG treatment in the 3 years prior to enrollment, prior intravesical chemotherapy is allowed;
- •Subjects with treatment failure included:
- •Subjects with recurrence after at least one intravesical course; BCG-relapsed subjects might include those intolerable to intravesical BCG therapy; Subjects with tumor grade progression after intravesical therapy;
- •The subject is willing to provide cystoscopic biopsy specimens for assessment
- •Age ≥ 18 years, male or female;
- •Performance status score (ECOG scale) ≤ 1 (0-1), and did not deteriorate within 7 days;
- •The subject must have normal organ and bone marrow functions within 28 days prior to enrollment into the study (based on normal range measured by the clinical site):
- •ANC > 1.0×109 /L; Platelet count > 100×109 /L; Hemoglobin > 9.0 g/dL; ALP < 2.5 times upper limit of normal range (should be less than 10 times upper limit of normal range if at the presence of bone metastasis); GFR (calculated using Cockcroft-Gault formula) ≥ 50 mL/min; INR < 1.5, except subjects who was undergoing Warfarin treatment at the time of screening.
- •Subjects who were receiving other medications with known or potential effects on the efficacy or pharmacokinetics of nitroxoline should be assessed and determined by the principal investigator.
- •Female subjects must be surgically sterilized or menopaused or must agree to take effective contraceptive measures during the treatment. Male subjects must be surgically sterilized or must agree to take effective contraceptive measures during treatment. Subjects must continue to take contraceptive measures for 3 months after the investigational therapy was completed. Definition of an effective contraceptive measure should be determined at the discretion of the principal investigator or any investigator appointed by the principal investigator.
