Brief Summary:
This is a Phase 1b/2, randomized, double-blind, placebo-controlled, multicenter, parallel-group study of B-701 plus docetaxel versus placebo plus docetaxel in the treatment of locally advanced or metastatic urothelial cell carcinoma in subjects who have relapsed after, or are refractory to standard therapy.

Condition or disease Intervention/treatment Phase
Locally Advanced or Metastatic Urothelial Cell Carcinoma Urinary Bladder Disease Urological Diseases Drug: B-701 Drug: Docetaxel Drug: placebo Phase 1 Phase 2

Detailed Description:
This is a Phase 1b/2, randomized, double-blind, placebo-controlled, multicenter, parallel-group, efficacy and safety study of B-701 plus docetaxel versus placebo plus docetaxel in the treatment of subjects with Stage IV, locally advanced or metastatic UCC who have relapsed after, or are refractory to at least one prior line of chemotherapy. This study is divided into 2 phases: Lead-In Phase and Randomized Phase; and the Lead-In Phase is divided into 3 cohorts. In Cohorts 1 and 2, all subjects will receive both B-701 plus docetaxel (unblinded). In Cohort 3, all subjects will receive B-701 only (unblinded). Subjects enrolling in Cohorts 2 and 3, as well as the Randomized Phase of the study, must have tumors with FGFR3 mutations or gene fusions.

Secondary Outcome Measures :
  1. Efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by objective response rates (ORR) [ Time Frame: up to 3-4 years ]
    Evaluate the efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by objective response rates (ORR)

  2. Efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by disease control rate (DCR) [ Time Frame: up to 3-4 years ]
    Evaluate the efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by disease control rate (DCR).

  3. Efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by duration of objective response (DOR) [ Time Frame: 3-4 years ]
    Evaluate the efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by duration of objective response (DOR)

  4. Efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by overall survival (OS) [ Time Frame: 3-4 years ]
    Evaluate the efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by overall survival (OS).

  5. Efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by quality of life (QOL) [ Time Frame: 3-4 years ]
    Evaluate the efficacy of B-701 plus docetaxel compared with placebo plus docetaxel as measured by quality of life (QOL).

  6. Safety and tolerability of B-701 plus docetaxel compared with placebo plus docetaxel [ Time Frame: 3-4 years ]
    Evaluate the safety and tolerability of B-701 plus docetaxel compared with placebo plus docetaxel in the treatment of subjects with UCC assessed through summaries of AEs.

  7. Safety and tolerability assessed through summaries of physical examination findings [ Time Frame: 3-4 years ]
    Evaluate the safety and tolerability of B-701 plus docetaxel compared with placebo plus docetaxel in the treatment of subjects with UCC as measured by physical examinations.

  8. Safety and tolerability assessed through summaries of laboratory laboratory results [ Time Frame: 3-4 years ]
    Evaluate the safety and tolerability of B-701 plus docetaxel compared with placebo plus docetaxel in the treatment of subjects with UCC as measured by laboratory results.

Criteria

Key Inclusion Criteria:

  • Available tissue that was obtained at or after the time the usbject was found to have muscle invasive disease and is of suitable quality and quantity and to assess the FGFR3 status by genetic testing. For subjects participating in the Randomized Phase only, if suitable archival tissue is unavailable, then a core biopsy of tumor tissue (metastatic or primary) must be obtained prior to randomization even if a blood sample sample was used to determine FGFR3 genetic status
  • Stage IV, locally advanced or metastatic urothelial bladder cancer or transitional cell carcinoma arising in another location of the urinary tract, including urethra, ureter, and renal pelvis
  • Relapsed after or are refractory to at least one prior line of chemotherapy which have not included a taxane (with the exception of Cohort 3 of the Lead-In Phase which will allow the enrollment of subjects with prior treatment with a taxane)
  • At least one prior chemotherapeutic regimen for advanced metastatic/recurrent disease, of which at least one regimen included a platinum agent (unless contraindicated)
  • Measurable disease according to RECIST v1.1 criteria
  • For Cohort 2, Cohort 3, and the Randomized Phase, tumor must be shown to have an FGFR3 mutation or gene fusion.

Main Exclusion Criteria:

  • Prior anti-cancer therapy within 4 weeks prior to Cycle 1, Day 1
  • Prior treatment with an inhibitor that is targeted primarily to FGFRs
  • Clinically significant comorbid medical conditions or lab abnormalities
  • History of major bleeding (requiring a blood transfusion ≥ 2 units) not related to a tumor within the past 12 months
  • History of clinically significant coagulation or platelet disorder in the past 12 months
  • Currently receiving anticoagulation treatment
  • Incomplete healing from wounds from prior surgery
  • Weight > 110kg
