Brief Summary

This is a Phase 1, open-label, dose escalation study to determine the safety and preliminary efficacy of voruciclib monotherapy in subjects with relapsed/refractory B cell malignancies or AML after failure of standard therapies or voruciclib in combination with venetoclax in subjects with relapsed or refractory AML

Detailed Description

This is a Phase 1, open-label, 3 + 3 dose escalation and expansion study to determine the safety and preliminary efficacy of voruciclib monotherapy in subjects with relapsed/refractory B cell malignancies or AML after failure of prior standard therapies or voruciclib in combination with venetoclax in subjects with relapsed or refractory AML. Escalation to the next higher dose level will depend on demonstrated safety and tolerability at each dose level.

Inclusion Criteria
  • Age ≥18 years

  • Histologically-confirmed diagnosis of Follicular lymphoma (FL), mantle cell lymphoma (MCL), marginal zone lymphoma (MZL), small lymphocytic lymphoma (SLL), chronic lymphocytic leukemia(CLL), diffuse large B-cell lymphoma (DLBCL), or AML

    a. Subjects must have disease that has relapsed or is refractory to 2 or more prior regimens and in need of treatment due to progressive disease

  • Presence of measurable disease defined per the 2008 International workshop on CLL guidelines, or by 2014 Lugano criteria for non-Hodgkin lymphoma (does not apply for AML subjects)

  • Adequate hematologic parameters unless clearly due to the disease under study

  • Adequate renal and hepatic function, per laboratory reference range at screening

Exclusion Criteria
  • History of pneumonitis of any cause

  • For CLL subjects: only known histological transformation to an aggressive lymphoma

  • For AML subjects:

    1. Acute promyelocytic leukemia
    2. Peripheral blast count > 25 × 10 9/L
  • Known central nervous system involvement

  • Significant cardiovascular disease

  • Significant screening ECG abnormalities

  • Subjects who require warfarin, anti-cancer therapeutics or investigational agents

  • Evidence of an ongoing systemic bacterial, fungal, or viral infection (including upper respiratory tract infections) at the time of start of voruciclib therapy

  • Prior solid organ transplantation

  • Receipt of an allogeneic transplant within 6 months or an autologous transplant within the preceding 3 months; evidence of ongoing graft-versus-host disease (GVHD)

  • Prior therapy with a cyclin-dependent kinase (CDK9) inhibitor

  • Symptomatic/uncontrolled HIV infection/AIDS, or currently taking contraindicated medications for HIV control

  • Ongoing immunosuppressive treatment including calcineurin inhibitors at the time of the start of study treatment, including systemic or enteric corticosteroids except as follows:

    1. Prior to the start of study treatment, subjects may be using systemic corticosteroids (≤20 mg/day of prednisone or equivalent), topical, or inhaled corticosteroids
    2. During study therapy, subjects may use systemic, topical, or enteric corticosteroids, if needed

Primary Outcome Measures
NameTimeMethod
Determine the safety and tolerability of voruciclib in combination with venetoclax in subjects with AML.2 years

Safety will be measured by the incidence of all AEs and SAEs, timing, grade \[CTCAE v4.03\] severity, seriousness, relatedness.

Tolerability will be measured by the incidence of DLTs (dose limiting toxicities)

Determine the safety and tolerability of voruciclib2 years

Safety will be measured by the incidence of all AEs and SAEs, timing, grade \[CTCAE v4.03\] severity, seriousness, relatedness.

Tolerability will be measured by the incidence of DLTs (dose limiting toxicities)

Secondary Outcome Measures
NameTimeMethod
Evaluate the PK of voruciclib2 years

Determined by the Area Under the Concentration time curve (AUC)

Evaluate the PK of voruciclib Cmax in combination with venetoclax Determined by the Area Under the Concentration time curve (AUC)2 years

Determined by the Area Under the Concentration time curve (AUC)

Progression Free Survival (PFS)2 years

defined as the time from the first dose of study drug administration (Cycle 1 Day 1) to disease recurrence or progression as defined by IWG criteria, or death on study

Overall Response Rate (ORR)2 years

defined as the sum of complete response (CR), complete remission with incomplete marrow recovery (CRi) and partial response (PR) for B-cell malignancies, or for AML the sum of CR/CRi rate by the 2017 European LeukemiaNet (ELN) criteria

Duration of Response (DOR)2 years

defined as the time from the initial determination of response to the time of disease progression or death on study, which ever occurs first
