Primary Outcome Measures:
  • Incidence, severity and relationship of treatment-emergent adverse events [ Time Frame: 1 month ]
  • Incidence, severity and relationship of treatment-emergent adverse events [ Time Frame: 4 months ]

Secondary Outcome Measures:
  • Pharmacodynamics [ Time Frame: 16 weeks ]
    Flow cytometry: Change from baseline over time for Tregs, NK cells and CD8+ central memory T-cells

  • Single-dose and steady-state Cmax [ Time Frame: 16 weeks ]
    Plasma levels of BNZ-1 will be measured after the 1st and last doses

  • Single-dose and steady-state AUC [ Time Frame: 16 weeks ]
    Plasma levels of BNZ-1 will be measured after the 1st and last doses

  • Steady-state Elimination half-life (t1/2) [ Time Frame: 16 weeks ]
    Plasma levels of BNZ-1 will be measured after the last dose


Other Outcome Measures:
  • Exploratory assessment of changes in lesion severity before and after treatment based on the modified Severity Weighted Assessment Tool (mSWAT) [ Time Frame: 16 weeks ]
  • Exploratory assessment of changes in lesion severity before and after treatment based on the Composite Assessment of Index Lesion Severity (CAILS) scoring tool [ Time Frame: 16 weeks ]
  • Exploratory assessment of Complete Response in LGL [ Time Frame: 16 weeks ]
    Normalization of CBC and LGL count

  • Exploratory assessment of Partial Response in LGL defined as 50% improvement in neutrophils or 50% reduction in transfusions [ Time Frame: 16 weeks ]

Estimated Enrollment: 24
Anticipated Study Start Date: September 15, 2017
Estimated Study Completion Date: April 30, 2018
Estimated Primary Completion Date: April 30, 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BNZ-1
IV PEGylated BNZ132-1-40
Drug: BNZ132-1-40
Injectable PEGylated peptide antagonist that binds to the common gamma chain (γc) signaling receptor for the cytokines interleukin (IL)-2, IL-9, and IL-15
Other Name: BNZ-1

Detailed Description:

This study is an open-label, multi-center, dose-ranging study to characterize the safety, tolerability, preliminary efficacy, and PK/PD of up to four dose levels of BNZ-1 administered weekly by IV infusion to adults diagnosed with LGL or CTCL. The study has four periods:

  • Screening Period
  • 4-week Treatment Period
  • 3-month Treatment Extension Period
  • 6-week Follow-up Period Subjects will be screened for eligibility within 30 days of study Day 1 (first dosing day of the 4-Week Treatment Period).

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Willing and able to consent and participate in the study.
  • Agrees not to receive any other investigational product or therapy while participating in this study.
  • Must be:

    • Currently using two forms of effective birth control (one of which is a barrier method) for the duration of the study for both males and females of childbearing potential. Effective methods of birth control include hormonal contraception (i.e., birth control pills, injected hormones, vaginal ring), intrauterine device, or barrier methods with spermicide (i.e., diaphragm with spermicide, condom with spermicide), or
    • Surgically sterile (i.e., hysterectomy, tubal ligation, vasectomy).
  • Eastern Cooperative Oncology Group (ECOG) Performance Status 0 to 2.
  • Life expectancy >1 year.

LGL-Specific:

  • Phenotypic studies (obtained within 8 weeks prior to study drug administration) from peripheral blood showing CD3+, CD57+ cells >400/mm³ or CD8+ cells >650/mm³.

    • Note: Complete blood count (CBC) and differential should be reported for the phenotyped sample.
  • Evidence for clonal T-cell receptor gene rearrangement (obtained within 1 year prior to study drug administration).

CTCL-Specific:

  • Histopathologically confirmed mycosis fungoides or Sézary syndrome (CTCL stage IIB or greater according to the European Organization for Research and Treatment of Cancer/International Society for Cutaneous Lymphomas [EORTC-ISCL] consensus classification) at study entry with progressive, persistent, or recurrent disease who have no available remaining standard therapeutic options (i.e., Refractory) as determined by the Investigator.

Exclusion Criteria:

  • Clinically relevant hepatic, neurological, pulmonary, ophthalmological, endocrine, renal, or other major systemic disease making implementation of the protocol or interpretation of the study results difficult, or that would put the subject at risk by participating in the study in the opinion of the Investigator.
  • History of or currently active primary or secondary immunodeficiency.
  • Known active bacterial, viral, fungal, mycobacterial infection, or other infection (including tuberculosis [TB] or atypical mycobacterial disease [but excluding fungal infection of nail beds, minor upper respiratory tract infection, and minor skin conditions]), or any major episode of infection that required hospitalization or treatment with IV antibiotics within 30 days of study drug administration or oral antibiotics within 14 days prior to study drug administration.
  • Received other investigational products or therapy in the 60 days prior to study drug administration.
