An Efficacy and Safety Study of Decitabine (DACOGEN) Plus Talacotuzumab (JNJ-56022473; Anti CD123) Versus Decitabine (DACOGEN) Alone in Participants With Acute Myeloid Leukemia (AML) Ineligible for Intensive Chemotherapy

Completed · Phase 2/Phase 3

Conditions studied: Leukemia, Myeloid, Acute

In brief

The primary objective of study Part A is to assess the safety of talacotuzumab (formerly CSL362) monotherapy and confirm the recommended Phase 2 dose (RP2D) in participants with acute myeloid leukemia (AML) for whom experimental therapy is appropriate. The primary objective of study Part B are to assess complete response (CR) rate and overall survival (OS) in participants with AML who are not eligible for intense induction chemotherapy and who are randomly assigned to receive decitabine plus talacotuzumab at the RP2D or decitabine alone.

Who can join

Age: 65 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• De novo or secondary acute myeloid leukemia (AML) (post myelodysplastic syndrome [MDS] or myeloproliferative neoplasm [MPN] or after leukemogenic chemotherapy) according to WHO 2008 criteria
• For Part A:
• Participants With AML: treatment naive or relapsed for whom experimental therapy is appropriate (as assessed by their treating physician)
• For Part B:
• Greater than or equal to (>=) 75 years of age or >= 65 up to 75 years of age and have at least one of the following: congestive heart failure or ejection fraction less than or equal to (<=) 50 percent; creatinine greater than (>) 2 milligram per deciliter (mg/dL); dialysis or prior renal transplant; documented pulmonary disease with lung diffusing capacity for carbon monoxide (DLCO) <= 65 percent of expected, or forced expiratory volume in 1 second (FEV1) <= 65 percent of expected or dyspnea at rest requiring oxygen; eastern cooperative oncology group (ECOG) performance status of 2; prior or current malignancy that does not require concurrent treatment; unresolved infection; comorbidity that, in the Investigator's opinion, makes the participant unsuitable for intensive chemotherapy and must be documented and approved by the Sponsor before randomization
• Previously untreated AML (except: emergency leukopheresis and/or hydroxyurea during the screening phase to control hyperleukocytosis but must be discontinued at least one day prior to start of study therapy)
• Not eligible for an allogeneic hematopoietic stem cell transplantation
• ECOG Performance Status score of 0, 1 or 2
• A woman must be either: Not of childbearing potential: postmenopausal (more than [>] 45 years of age with amenorrhea for at least 12 months; If, of childbearing potential must be practicing a highly effective method of birth control
• A woman of childbearing potential must have a negative serum (beta-human chorionic gonadotropin [beta-hCG]) or urine pregnancy test at screening
• A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control eg, either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository for at least 3 months after last study treatment

You may not qualify if…

• Acute promyelocytic leukemia with t(15;17), or its molecular equivalent (PML-RARalpha)
• For Part B only: Known leukemic involvement or clinical symptoms of leukemic involvement of the central nervous system
• Participants who received prior treatment with a hypomethylating agent
• For Part A only: Participants who did not recover from all clinically significant toxicities (excluding alopecia and hematologic toxicities) of any previous surgery, radiotherapy, targeted therapy, or chemotherapy to less than or equal to Grade 1
• Any uncontrolled active systemic infection that requires treatment with intravenous (IV) antibiotics
• A history of human immunodeficiency virus (HIV) antibody positive or tests positive for HIV if tested at screening
• Active systemic hepatitis infection requiring treatment or other clinically active liver disease
