NCT03552796

Brief Summary

This phase I trial studies the side effects and best dose of recombinant EphB4-HSA fusion protein (sEphB4-HSA), and to see how well it works in treating participants with bladder cancer that has come back or that isn't responding to bacillus Calmette-Guerin (BCG) vaccine treatment. sEphB4-HAS prevents tumor cells from multiplying and blocks several compounds that promote the growth of blood vessels that bring nutrients to the tumor. Giving sEphB4-HSA may work better in treating participants with bladder cancer.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Incidence of adverse events

    Adverse events will be evaluated in accordance with the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

    Up to 6 months

  • Maximum tolerated dose (MTD) and recommended phase II dose (RP2D)

    The MTD is defined as the highest dose tested in which none or only one patient experienced DLT attributable to the study drug, when 6 patients were treated at that dose and are evaluable for toxicity. The MTD is one dose level below the lowest dose tested in which 2 or more patients experienced DLT attributable to the study drug. The MTD will be the RP2D.

    Up to 6 months

Study Arms (1)

sEphB4-HSA

EXPERIMENTAL

Cohorts of at least 3 participants each will be treated with escalating doses of sEphB4-HAS at 25mg, 50 mg, 75mg, 100 mg, and 125 mg administered intravesically over 2 hours once a week for 6 consecutive weeks to determine the maximum tolerated dose (MTD) and recommended phase II dosing (RP2D). Cycle repeats every 6 weeks in the absence of disease progression or unacceptable toxicity.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with bladder CIS, or completely resected high grade Ta/T1 lesions that are BCG unresponsive; unresponsive is BCG refractory and/or BCG relapsing
  • BCG refractory: persistent high-grade disease at 6 months despite receiving at least 5-6 induction instillations and at least one maintenance (two of three instillations) in a 6 month period
  • BCG relapsing: recurrence of high-grade disease after achieving a disease-free state at 6 months after receiving at least 5-6 induction instillations and at least one maintenance (two of three instillations) in a 6 month period
  • Eastern Cooperative Oncology Group performance status 0 to 2
  • Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization for release of personal health information
  • NOTE: HIPAA authorization may be included in the informed consent or obtained separately
  • Females must not be breastfeeding
  • Patients must be willing to undergo additional radiologic imaging while on study
  • Leukocytes \>= 3,000/mcL
  • Absolute neutrophil count \>= 1,500/mcL
  • Platelets \>= 100,000/mcl
  • Total bilirubin =\< 1.5 X institutional upper limit of normal
  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 X institutional upper limit of normal
  • Creatinine =\< 1.5 X institutional upper limit of normal
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
  • +7 more criteria

You may not qualify if:

  • If they are undergoing or have undergone in the past 4 weeks (28 days) any other therapy for their cancer, including radiation therapy and chemotherapy
  • If they have a major systemic infection requiring antibiotics 72 hours or less prior to the first dose of study drug
  • If they have untreated central nervous system (CNS) metastasis; patients whose CNS metastases have been treated by surgery or radiotherapy, who are no longer on corticosteroids, and who are neurologically stable may be enrolled in the dose escalation portion of the trial
  • If they have New York Heart Association (NYHA) class 3 or 4; myocardial infarction, acute coronary syndrome, diabetes mellitus with ketoacidosis or chronic obstructive pulmonary disease (COPD) requiring hospitalization in the preceding 6 months; or any other intercurrent medical condition that contraindicates treatment with sEphB4-HSA or places the patient at undue risk for treatment related complications
  • If they have any other condition, including mental illness or substance abuse, deemed by the investigator to be likely to interfere with a patient?s ability to sign informed consent, cooperate and participate in the study, or interferes with the interpretation of the results
  • If they are pregnant or lactating
  • If they are on any dose of warfarin or are on full dose anticoagulation with other agents, including low molecular weight heparin, antithrombin agents, anti-platelet agents and full dose aspirin within 7 days prior to first dose of study drug; patients on prophylactic doses of low-molecular weight heparin are allowed
  • If they have had any active bleeding in the last =\< 4 weeks or have an otherwise known bleeding diathesis
  • Patients may not be receiving any other investigational agents
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to agent(s) or other agents used in study
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Patients must not be pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants
  • Evidence of a history of a stroke or myocardial infarction within the last 6 months prior to study enrollment
  • Previous intravesical immunotherapy less than 3 months before study entry; Note: if a patient is eligible for the study but has had intravesical immunotherapy within the past 3 months, they can enroll in the study and initiation of treatment of the drug will be delayed until a minimum of 90 days has passed since the previous treatment
  • Renal and hepatic function values exceeding 2 times the upper normal value
  • +2 more criteria
