NCT03672539

Brief Summary

This phase II trial studies the side effects and how well liposome-encapsulated daunorubicin-cytarabine and gemtuzumab ozogamicin work in treating patients with acute myeloid leukemia that has come back (relapsed) or that does not respond to treatment (refractory) or high risk myelodysplastic syndrome. Drugs used in chemotherapy, such as liposome-encapsulated daunorubicin-cytarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to a toxic agent called calicheamicin. Gemtuzumab ozogamicin attached to CD33 positive cancer cells in a targeted way and delivers calicheamicin to kill them. Giving liposome-encapsulated daunorubicin-cytarabine and gemtuzumab ozogamicin together may be an effective treatment for relapsed or refractory acute myeloid leukemia or high risk myelodysplastic syndrome.

Study Arms (1)

Treatment (CPX-351, gemtuzumab ozogamicin)

EXPERIMENTAL

INDUCTION CYCLE: Patients receive liposome-encapsulated daunorubicin-cytarabine IV over 90 minutes on days 1, 3, and 5 of cycle 1 and days 1 and 3 of cycle 2 and gemtuzumab ozogamicin IV over 120 minutes on day 1. Treatment repeats every 28 days for up to 2 cycles in the absence of unacceptable toxicity. CONSOLIDATION CYCLE: Patients receive liposome-encapsulated daunorubicin-cytarabine IV over 90 minutes on days 1 and 3 and gemtuzumab ozogamicin over 120 minutes on day 1. Treatment repeats every 28 days for up to 2 cycles in the absence of unacceptable toxicity. MAINTENANCE CYCLE: Patients receive gemtuzumab ozogamicin IV over 120 minutes on day 1. Treatment repeats every 6 weeks for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of CD33 positive (\>= 3%), relapsed refractory acute myeloid leukemia by World Health Organization (WHO) criteria. Patients with post-hypomethylating agent (post-HMA) failure high-risk myelodysplastic syndrome (MDS), as defined by the presence of \> 10% blasts, are also eligible.
  • Patients with MDS or chronic myelomonocytic leukemia (CMML) who received hypomethylating agent based-therapy for the MDS or CMML and progress to AML are eligible at the time of diagnosis of AML regardless of any prior therapy for MDS or CMML. The WHO classification will be used for AML.
  • Eastern Cooperative Oncology Group (ECOG) performance status score of =\< 2.
  • Total serum bilirubin =\< 2 x upper limit of normal (ULN). Patients with known Gilbert's syndrome may have a total bilirubin up to =\< 3 x ULN.
  • Serum creatinine =\< 2.0 mg/dl.

  • Females of childbearing potential must have a negative serum or urine beta human chorionic gonadotropin (b-HCG) pregnancy test result within 14 days prior to the first dose of study drugs and must agree to use one of the following effective contraception methods during the study and for 30 days following the last dose of study drug. Effective methods of birth control include: Birth control pills, shots, implants (placed under the skin by a health care provider) or patches (placed on the skin); intrauterine devices (IUDs); condom or occlusive cap (diaphragm or cervical/vault caps) used with spermicide; abstinence.
  • Females of non-childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation, oophorectomy, and/or hysterectomy.
  • Males who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 30 days following the last dose of study drug.
  • Patients or their legally authorized representative must provide written informed consent.
