A Study Evaluating Intensive Chemotherapy With or Without Glasdegib or Azacitidine With or Without Glasdegib In Patients With Previously Untreated Acute Myeloid Leukemia

A RANDOMIZED (1:1), DOUBLE-BLIND, MULTI-CENTER, PLACEBO CONTROLLED STUDY EVALUATING INTENSIVE CHEMOTHERAPY WITH OR WITHOUT GLASDEGIB (PF-04449913) OR AZACITIDINE (AZA) WITH OR WITHOUT GLASDEGIB IN PATIENTS WITH PREVIOUSLY UNTREATED ACUTE MYELOID LEUKEMIA

Summary

Glasdegib is being studied in combination with azacitidine for the treatment of adult patients with previously untreated acute myeloid leukemia (AML) who are not candidates for intensive induction chemotherapy (Non-intensive AML population). Glasdegib is being studied in combination with cytarabine and daunorubicin for the treatment of adult patients with previously untreated acute myeloid leukemia (Intensive AML population).

Detailed description

Two separate registration trials conducted under one protocol number are proposed to adequately and independently evaluate the addition of glasdegib in intensive and non-intensive chemotherapy populations. Each study will have an experimental treatment arm and a placebo arm. Endpoints are the same for each study except where specifically indicated. Assignment to the Intensive Study or the Non-Intensive Study will be made by the Investigator based on the 2017 European LeukemiaNet (ELN) recommendations. Study B1371019 is a randomized (1:1), double-blind, multi-center, placebo controlled study of chemotherapy in combination with glasdegib versus chemotherapy in combination with placebo in adult patients with previously untreated AML. Glasdegib is being studied in combination with azacitidine for the treatment of adult patients with previously untreated acute myeloid leukemia (AML) who are not candidates for intensive induction chemotherapy (Non-intensive AML population). Glasdegib is being studied in combination with cytarabine and daunorubicin for the treatment of adult patients with previously untreated acute myeloid leukemia (Intensive AML population).

Conditions

• Leukemia, Myeloid, Acute

Interventions

Type	Name	Description
DRUG	glasdegib	Daily Glasdegib (100 mg, PO), beginning on Day 1 and is to continue up to 2 years post randomization. Following consolidation therapy, glasdegib or placebo will be administered daily for up to 2 years after randomization or until they have minimal residual disease (MRD) negative disease, whichever comes first. Daily Glasdegib (100 mg, PO) or matching placebo will continue throughout Induction(s) and Consolidation therapies regardless of dose modifications/delays in the chemotherapy.
DRUG	daunorubicin + cytarabine	'7+3' (cytarabine 100 mg/m2, IV for 7 days by continuous infusion and daunorubicin 60 mg/m2 for 3 days). If a second induction is needed, Investigators may choose either a 5 day cytarabine continuous infusion plus daunorubicin for 2 days ('5+2') or a 7 day cytarabine continuous infusion plus daunorubicin for 3 days ('7+3');
DRUG	azacitidine	Azacitidine (75 mg/m2, SC or IV) daily for 7 days, in 28 day cycles for as long as they do not meet the criteria for disease progression, unacceptable toxicity, consent withdrawal, or death.
DRUG	Placebo	Matching placebo (PO) given on Day 1 and is to continue up to 2 years post randomization. Following consolidation therapy, placebo will be administered daily for up to 2 years after randomization or until they have MRD negative disease, whichever comes first. Daily placebo will continue throughout Induction(s) and Consolidation therapies regardless of dose modifications/delays in the chemotherapy.
DRUG	Placebo	Matching placebo (PO) is to be administered by mouth daily beginning on Day 1 of chemotherapy and will continue if subjects demonstrate reasonable evidence of clinical benefit and do not meet the criteria for progression regardless of any delays/modifications in the chemotherapy treatment. Subjects will continue placebo until disease progression, unacceptable toxicity, consent withdrawal, or death, whichever comes first.
DRUG	glasdegib	Glasdegib 100 mg PO QD is to be administered by mouth daily beginning on Day 1 of chemotherapy and will continue if subjects demonstrate reasonable evidence of clinical benefit and do not meet the criteria for progression regardless of any delays/modifications in the chemotherapy treatment. Subjects will continue glasdegib until disease progression, unacceptable toxicity, consent withdrawal, or death, whichever comes first.
DRUG	cytarabine	Consolidation with single agent cytarabine 3 g/m2 IV for adults \<60 years and 1 g/m2 for adults 60 years over 3 BID on Days 1, 3, and 5, every 28 days for up to 4 cycles or alternative single agent cytarabine consolidation schedules may be used per local prescribing information.
PROCEDURE	HSCT	If required, and done per standard of care post Induction(s).
