A Study of Venetoclax in Combination With Navitoclax and Chemotherapy in Subjects With Relapsed/Refractory Acute Lymphoblastic Leukemia or Relapsed/Refractory Lymphoblastic Lymphoma

Phase 1
Completed
Conditions
Lymphoblastic Lymphoma
Acute Lymphoblastic Leukemia (ALL)
Interventions
Registration Number
NCT03181126
Lead Sponsor
AbbVie
Brief Summary

This dose-escalating study is to determine the safety, pharmacokinetics, and preliminary efficacy of venetoclax in combination with navitoclax and chemotherapy in adult and pediatric participants with relapsed/refractory acute lymphoblastic leukemia (ALL) or relapsed/refractory lymphoblastic lymphoma. A safety expansion cohort of approximately 20 patients may be enrolled in addition to the 50 participants in dose-escalation cohort.

  • Must be able to swallow pills.

  • Must have adequate hepatic and kidney function.

  • Must have adequate performance status:

    • Participants less than or equal to 16 years of age: Lansky greater than or equal to 50

Exclusion Criteria
  • Participant has central nervous system (CNS) disease with cranial involvement that requires radiation.

  • Participants who are less than 100 days post-transplant, or greater than 100 days post-transplant with active graft versus host disease (GVHD), or are still continuing post-transplant immunosuppressant therapy within 7 days prior to the first dose of study drug.

  • Participants who have received any of the following prior to the first dose of study drug:

    • Inotuzumab within 30 days (if participant received inotuzumab > 30 days prior to Day 1, must have ALT, AST and bilirubin < ULN).

    • A biologic agent (i.e., monoclonal antibodies) for anti-neoplastic intent within 30 days

    • CAR-T infusion or other cellular therapy within 30 days

    • Any anti-cancer therapy including blinatumomab, chemotherapy, radiation therapy targeted small molecule agents or investigational agents within 14 days, or 5 half-lives, whichever is shorter

      • Exception: Philadelphia Chromosome (Ph)+ ALL subjects on TKIs at Screening may enroll and remain on Tyrosine Kinase Inhibitor (TKI) therapy to control disease. Participants on venetoclax at screening may enroll and remain on venetoclax.
    • Steroid therapy for anti-neoplastic intent within 5 days

    • Hydroxyurea that is ongoing (hydroxyurea is permitted up to the first dose)

    • A strong or moderate CYP3A inhibitor or inducer within 7 days

    • Aspirin within 7 days, or 5 half-lives, whichever is longer

    • An excluded antiplatelet/anticoagulant drug or a herbal supplement that affects platelet function within 7 days, or 5 half-lives, whichever is longer

  • Participants with malabsorption syndrome or any other condition that precludes enteral administration.

Primary Outcome Measures
NameTimeMethod
Tmax of Venetoclax + NavitoclaxUp to approximately 9 months

Time to Cmax (Tmax) of Venetoclax + Navitoclax

Cmax of Venetoclax + NavitoclaxUp to approximately 9 months

Maximum observed plasma concentration (Cmax) of venetoclax + navitoclax

CL/F of Venetoclax + NavitoclaxUp to approximately 9 months

Apparent oral clearance (CL/F) of venetoclax + navitoclax

Number of participants with dose-limiting toxicities (DLT)Up to approximately 28 days after initial dose of study drug

A DLT is any Grade 3 or higher non-hematologic adverse event (AE) with exceptions outlined in the protocol. AEs and toxicities that occur beyond the DLT assessment period will also be evaluated by the investigator and AbbVie and may be considered as dose-limiting.

AUC of Venetoclax + NavitoclaxUp to approximately 9 months

Area under the plasma concentration-time curve (AUC) of venetoclax + navitoclax

Secondary Outcome Measures
NameTimeMethod
Number of Participant who Proceed to Stem Cell Transplantation or Chimeric antigen receptor T-cell (CAR-T) TherapyUp to 9 months after the last subject has enrolled into the study

Determine the number of participants who proceed to stem cell transplantation or CAR-T therapy.

Progression-free survival (PFS)Up to 9 months after the last subject has enrolled into the study

PFS is defined as the number of days from the date of enrollment to the date of earliest disease progression or death.

Partial Response (PR) rateUp to 9 months after the last subject has enrolled into the study

PR defined as no peripheral blasts or peripheral blood absolute blast count decreased by ≥ 50% from baseline, bone marrow with 5 - 25% blasts and at least a 50% decrease in bone marrow blast percent from baseline, no evidence of extramedullary disease.

Overall survival (OS)Up to 9 months after the last subject has enrolled into the study

OS is defined as the number of days from the date of enrollment to the date of death.

Objective response rate (ORR)Up to 9 months after the last subject has enrolled into the study

The proportion of subjects with objective response rate (complete response \[CR\] + CR incomplete recovery \[CRi\] + CR without platelet recovery \[CRp\]) for ALL subjects and (CR+PR) for LL subjects.

Complete Response (CR) rateUp to 9 months after the last subject has enrolled into the study

CR defined as hematologic recovery (absolute neutrophil count \[ANC\] greater than or equal to 500/μL; platelet counts greater than or equal to 75,000/μL), evidence of trilineage hematopoiesis in the bone marrow and less than 5% blasts in the bone marrow, absence of circulating blasts, and no evidence of extramedullary disease.
