Expanded Treatment Protocol for Adults With FLT3-ITD Mutated Relapsed or Refractory Acute Myeloid Leukemia (AML) to Receive Quizartinib

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03746912
Expanded Access Status : No longer available
First Posted : November 20, 2018

Brief Summary:

An expanded access program (EAP):

  • Allows doctors to give medicine to patients,
  • Before it is approved by health authorities.

This EAP is for:

  • Quizartinib
  • Patients with FLT3-ITD mutated AML,
  • AML that has come back, or
  • Is resistant to other therapies.

A participant will receive quizartinib if:

  • The doctor submits a request,
  • The participant is eligible, and
  • The country allows the EAP.

Condition or disease Intervention/treatment
Acute Myeloid Leukemia With Gene Mutations Drug: Quizartinib Dihydrochloride

Detailed Description:

This is an expanded access program (EAP) providing access to quizartinib for participants with Relapsed/Refractory FLT3-ITD mutated AML, prior to approval by local regulatory agencies. Availability of the EAP is dependent upon physician request, country eligibility and local/country regulations. EAP countries included Austria, Belgium, Brazil, Denmark, France, Germany, Ireland, Italy, Netherlands, Norway, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, United Kingdom, and United States. Physicians may request access to the EAP for participants who they feel may benefit from quizartinib and meet the eligibility criteria.

Participants may continue quizartinib until there is a lack of clinical benefit or the occurrence of unacceptable toxicity. Treatment should be interrupted for allogeneic hematopoietic stem cell transplantation (HSCT), but may be resumed after the transplant.

Participant enrollment may continue until 18 months after regulatory approval, depending on country regulation; or until such time the marketed medication is available, whichever occurs first.

Participants will be asked to follow the care as outlined by their treating physician. Participants will be followed for 30 days after their final treatment or until the patient is transitioned to commercially available product. Physicians will be required to report safety data to Daiichi-Sankyo Inc.

Quizartinib is currently under development for the treatment of patients 18 years of age or older with relapsed (including after HSCT) or refractory FLT3-ITD mutated AML, and has been granted Fast Track Status in the US and an Orphan Drug Indication in the United States, Europe and Asia.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All

Inclusion Criteria:

Participants must satisfy all of the following inclusion criteria prior to receive treatment:

  1. Has provided written informed consent as approved per local regulations with privacy language in accordance with national regulations (eg, Health Insurance Portability and Accountability Act [HIPAA] authorization for US sites) prior to any protocol-related procedures
  2. Is 18 years of age or the minimum legal adult age (whichever is greater) at the time of informed consent
  3. Has morphologically documented primary AML or AML secondary to myelodysplastic syndrome (MDS) or other myeloproliferative neoplasms (MPN), as defined by the World Health Organization (WHO) 2008 classification with ≥5% blasts in bone marrow, with or without extramedullary disease
  4. Is in relapse or refractory (R/R) to prior therapy, with or without HSCT

    1. Refractory is defined as:

      • participant did not achieve complete remission (CR), CR with incomplete platelet recovery (CRp), or CR with incomplete hematological recovery (CRi) under initial intensive therapy, or
      • did not achieve CR, CRp, CRi, or partial remission (PR) under initial sufficient time course of treatment with hypomethylating agents or low-dose cytarabine (LoDAC)
      • must have received at least one complete block of induction therapy seen as the optimum choice of therapy to induce remission or at least 4 cycles of therapy with a hypomethylating agent deemed sufficient to induce a response
    2. Relapse is defined as: relapse diagnosed by bone marrow assessment or by the appearance of peripheral blasts after the achievement of CR, CRp, or CRi, as defined by 2003 International Working Group criteria after AML therapy with or without consolidation or maintenance, and with or without HSCT
  5. Has documented FLT3-ITD mutation in bone marrow or peripheral blood in relation R/R disease
  6. Prior treatment with kinase inhibitors, including FLT3 targeted therapy or investigational FLT3 inhibitors is allowed
  7. Has an Eastern Cooperative Oncology Group (ECOG) performance score 0-3
  8. Discontinued prior AML treatment before the start of protocol treatment (except hydroxyurea or other treatment to control leukocytosis) for at least 2 weeks for cytotoxic agents, or for at least 5 half-lives for non-cytotoxic agents
  9. Has creatinine clearance >25 mL/min, as calculated with the Cockcroft-Gault formula
  10. Has serum potassium, magnesium, and calcium (serum calcium corrected for hypoalbuminemia) within institutional normal limits. Participants with electrolytes outside the normal range will be eligible if these values are corrected upon retesting following any necessary supplementation
  11. Total serum bilirubin ≤1.5 × upper limit of normal (ULN)
  12. Has serum aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) ≤2.5 × ULN

Exclusion Criteria:

Participants who meet any of the following criteria will be disqualified from enrollment:

  1. Is eligible to enroll in a recruiting clinical trial of quizartinib or is currently enrolled in an ongoing clinical trial of quizartinib
  2. Has previously participated in a randomized clinical study of quizartinib with an endpoint of survival that is not closed for efficacy
  3. Has acute promyelocytic leukemia (AML subtype M3)
  4. Has persistent, clinically significant ≥Grade 3 non-hematologic toxicity from prior AML therapy
  5. Has clinically significant acute graft-versus-host disease (GvHD) or GVHD requiring initiation of treatment or treatment escalation within 21 days, and/or ≥Grade 3 persistent or clinically significant non-hematologic toxicity related to HSCT
