Brief Summary

Phase 1 dose escalation study of ZN-d5 in subjects with relapsed or refractory non-Hodgkin lymphoma (NHL) or acute myeloid leukemia (AML).

Detailed Description

This is an open-label multicenter Phase 1 dose escalation study evaluating the safety, tolerability, clinical activity, pharmacokinetics and pharmacodynamics of the novel BCL-2 inhibitor ZN-d5 in subjects with (NHL) or (AML) in order to determine the recommended phase 2 dose of ZN-d5.

Inclusion Criteria

NHL: relapsed or refractory NHL including DLBCL, FL, MZL, MCL, LCL, LPL and PTC

  • Subjects must have received at least 2 prior lines of therapy and have either failed or not be eligible for any available therapies expected to provide clinical benefit and have measurable disease.

AML: Primary, secondary, or treatment-related AML, relapsed or refractory to prior therapy, which may include failure of one cycle of induction therapy.

  • White blood cell count < 25 Γ— 109/L. Cytoreduction prior to treatment is acceptable.

  • Eastern Cooperative Oncology Group performance status ≀ 2.
  • Estimated life expectancy of at least 12 weeks.
  • Adequate hematologic and organ function, including creatinine clearance β‰₯ 60 mL/min.

Key

Exclusion Criteria
  • Recent interventions including major surgery, radiation therapy, stem cell transplant.
  • Treatment with anti-neoplastic agents with 5 half-lives.
  • Significant unresolved toxicity from prior treatments including active GVHD.
  • Active central nervous system disease.

Primary Outcome Measures
NameTimeMethod
Observed Dose Limiting ToxicitiesThrough completion of Cycle 1; 1 to 2 months.

Observed Dose Limiting Toxicities (DLTs) in DLT-evaluable subjects.

Incidence and severity of AEs, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events, v 5.0Through study completion, typically < 12 months

Safety profile of ZN-d5.

Secondary Outcome Measures
NameTimeMethod
For AML, remission rate based on European LeukemiaNet 2017 criteriaThrough study completion, typically < 12 months

Evaluate remission rate according to the European LeukemiaNet 2017 criteria (Overall Response Rate (ORR) defined as Complete Remission (CR) + CR with incomplete hematologic recovery (CRi) + Morphologic Leukemia-Free State (MLFS) + Partial Remission (PR)) for AML subjects.

For AML, duration of remission based on European LeukemiaNet 2017 criteriaThrough study completion, typically < 12 months

Evaluate duration of remission according to the European LeukemiaNet 2017 criteria.

Pharmacokinetic parameters for ZN-d5 - Cmaxapproximately 6 months

Characterize the Pharmacokinetics of ZN-d5 in subjects with NHL and AML using peak plasma concentration (Cmax).

Pharmacokinetic parameters for ZN-d5 - Tmaxapproximately 6 months

Characterize the Pharmacokinetics of ZN-d5 in subjects with NHL and AML using the time to maximum plasma concentration (Tmax).

Pharmacokinetic parameters for ZN-d5 - AUCapproximately 6 months

Characterize the Pharmacokinetics of ZN-d5 in subjects with NHL and AML using area under the plasma concentration versus time curve (AUC).

For NHL, evaluate response according to the Lugano 2014 classificationThrough study completion, typically < 12 months

Evaluate response according to the Lugano 2014 classification for NHL subjects. The Lugano Classification is based on a 5-point scale for scoring of metabolically active lesions detected by PET-CT in FDG-avid lymphomas, and lesion size for non-FDG-avid tumors. A complete metabolic response would require a score of 1 or 2 on target and non-target lesions and the spleen for high-risk disease, and a score of 1,2, or 3 for low-risk disease. A partial response, no response, or progression would require a score of 4 or 5 for low-risk disease, and a score of 3, 4, or 5 for high-risk disease.
