Brief Summary:
The purpose of this research study is to test the safety of avelumab and AVB-S6-500 and see what effects (good and bad) this combination treatment has on patients with advanced urothelial carcinoma.

Condition or disease Intervention/treatment Phase
Urothelial Carcinoma Drug: Avelumab Drug: AVB-S6-500 Phase 1

Detailed Description:

Patients will have tests and exams to see if they are eligible for the clinical trial. If found eligible, the patient will receive treatment with avelumab and AVB-S6-500 by vein once every two weeks.

This study has two parts in order to determine the maximum tolerated dose of AVB-S6-500. If the patient is enrolled on the first dose level, the patient will be treated at a higher dose every two weeks with AVB-S6-500. If the patient is enrolled on the second dose level, the patient will be receive AVB-S6-500 only once a week at a lower dose. The patient would continue to receive avelumab twice weekly at the same dose.

Patients will receive the study treatment as long as there is evidence that the tumor is not growing or spreading and they are not having any unacceptable, bad side effects.

Patients will be monitored during treatment with tests and exams and after treatment completion for up to one year.

Primary Outcome Measures :
  1. Safety and Tolerability [ Time Frame: up to 2 years ]
    To investigate the safety and tolerability of the study drug combination for Avelumab with AVB-S6-500

Secondary Outcome Measures :
  1. Progression Free Survival [ Time Frame: up to two years ]
    period from the time of patient enrollment until disease progression, death, or date of last contact or to the date of censoring (dropout, end of study or death)

  2. Clinical Benefit Rate [ Time Frame: up to two years ]
    proportion of patients with complete or partial response, or stable disease per RECIST 1.1 on treatment with avelumab and ABV-S6-500

  3. Duration of Response [ Time Frame: up to two years ]
    defined as the period from the date of confirmed tumor response until disease progression, death, or date of last contact or to the date of censoring (dropout, end of study or death)

  4. Overall Survival [ Time Frame: up to two years ]
    the period from patient enrollment until death, or date of last contact or to the date of censoring (end of study)

  5. Investigator assessed Objective Response Rate [ Time Frame: up to 2 years ]
    To evaluate the antitumor efficacy of avelumab and AVB-S6-500 as measured by the objective response rate assessed by the investigator

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Age ≥18 years
  2. Histologically confirmed locally advanced unresectable (T4b or N2/N3 disease) or metastatic urothelial cancer (including renal pelvis, ureters, urinary bladder, urethra).
  3. Eligible patients must have had either:

    1. Progressed after treatment with at least 1 prior platinum-containing regimen, (e.g., received at least 2 cycles of cisplatin or carboplatin-based regimen) for inoperable locally advanced unresectable or metastatic urothelial carcinoma, OR OR
    2. Experienced disease progression or recurrence within 12 months of completion of neoadjuvant or adjuvant cisplatin-based chemotherapy, OR OR
    3. Ineligible for cisplatin-based chemotherapy due to eastern co-operative oncology group (ECOG) performance status 2, grade ≥2 neuropathy, GFR<60 mL/min, grade ≥2 hearing loss or New York Heart Association class III or worse congestive heart failure.
    4. Declined platinum (cisplatin or carboplatin) based chemotherapy after informed discussion with the treating investigator
  4. Available pretreatment baseline tumor specimen or willingness to undergo biopsy of primary or metastatic lesion if archived specimen is not available.
  5. ECOG performance status of ≤2
  6. At least one measurable lesion by RECIST version 1.1
  7. Patients who are able to understand and sign the informed consent form.
  8. Ability to comply with protocol
  9. Adequate hematologic and end-organ function per protocol
  10. For women of childbearing potential: Negative serum or urine pregnancy test at screening.
  11. For both male and female subjects: agreement to remain abstinent (refrain from heterosexual intercourse) or use highly effective contraceptive methods that result in a failure rate of <1% per year during the treatment period and for at least 30 days after the last dose of study drug

Exclusion Criteria:

  1. Concurrent systemic treatment with an anticancer treatment or investigational drug within 28 days. Palliative radiation to symptomatic primary tumor or metastases is permitted as long as there are other measurable lesions present outside of the radiation field.
