Trial Outcomes & Findings for Chronic Myelogenous Leukemia or Philadelphia Chromosome Positive Acute Lymphoblastic Leukemic Study (NCT NCT00978731)

Last Updated: 2011-04-28

Results Overview

AEs: any new untoward medical occurrences/worsening of pre-existing medical condition, whether or not related to study drug. SAE: any AE that resulted in death; was life threatening; resulted in persistent/significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was a congenital anomaly/birth defect; or was an overdose. Participants who discontinued the study due to AEs were recorded. These data differ from that in the Participant Flow section. This is because the data were collected on 2 different pages of the Case Report Form and were not reconciled.

Measure	Chronic Myelogenous Leukemia (CML): QD Dosing at Study Entry Participants with Chronic Myelogenous Leukemia (CML)were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). A total daily dose (TDD) of 50 mg, 75 mg, 105 mg, 140 mg or 180 mg dasatinib was taken once daily (QD). Participants were dosed on 1 of 3 schedules (5 days on, 2 days off; 6 days on, 1 day off or continuous daily dosing) and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.	CML: BID Dosing at Study Entry Participants with CML were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). Treatment was received BID, with a TDD of 50 mg, 70 mg, 100 mg, 140 mg, 180 mg or 240 mg dasatinib. Participants were dosed on 1 of 3 schedules (5 days on, 2 days off; 6 days on, 1 day off or continuous daily dosing) and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.	Accelerated Phase CML: BID Dosing at Study Entry Participants with accelerated phase CML were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). A TDD of 50 mg, 75 mg, 105 mg, 120 mg, 140 mg or 180 mg dasatinib was taken QD or split into 2 doses and taken BID (TDD of 50 mg, 70 mg, 100 mg, 140 mg, 180 mg or 240 mg). Participants were dosed on 1 of 3 schedules (5 days on, 2 days off; 6 days on, 1 day off or continuous daily dosing) and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.	Myeloid Blast Phase CML: BID Dosing at Study Entry Participants with myeloid blast phase CML were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). A TDD of 50 mg, 75 mg, 105 mg, 120 mg, 140 mg or 180 mg dasatinib was taken QD or split into 2 doses and taken BID (TDD of 50 mg, 70 mg, 100 mg, 140 mg, 180 mg or 240 mg).

PRIMARY outcome

Timeframe: From start of study to final assessment (up to 32.2 months).

Population: All treated participants.

Dose interruptions and reductions were allowed, in order to optimize individual participant's hematologic, cytogenetic, and molecular response while maintaining and evaluating safety and tolerability of long-term exposure to dasatinib. A dose reduction is defined as the administration of a dose at a lower level compared to previous dose and such that reduced dose, or a lower dose, is given at least 4 consecutive times. In determining the reductions, dose level would be compared to the previous non-null dose. Dose interruption is defined as a complete omission of dosing for 4 consecutive times.

SECONDARY outcome

Timeframe: Baseline to study discontinuation. Median duration of exposure (on-study time) was 23.4 months.

Population: All treated participants.

Interval between randomization date \& earliest date of disease progression/death due to any cause, assessed by the Independent Radiology Review Committee (IRRC) using modified World Health Organization (WHO) criteria to define progressive disease (PD): \>=25% increase in sum of products of diameters (SOPD) of lesions compared with smallest SOPD recorded for study period or progression of any non-index lesion/appearance of new lesion. If no progression/death, date of last tumor assessment used. For participants who had no on-study tumor assessments \& were still alive, date of randomization used.

Measure	Chronic Myelogenous Leukemia (CML): QD Dosing at Study Entry n=46 Participants Participants with Chronic Myelogenous Leukemia (CML)were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). A total daily dose (TDD) of 50 mg, 75 mg, 105 mg, 140 mg or 180 mg dasatinib was taken once daily (QD). Participants were dosed on 1 of 3 schedules (5 days on, 2 days off; 6 days on, 1 day off or continuous daily dosing) and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.	CML: BID Dosing at Study Entry Participants with CML were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). Treatment was received BID, with a TDD of 50 mg, 70 mg, 100 mg, 140 mg, 180 mg or 240 mg dasatinib. Participants were dosed on 1 of 3 schedules (5 days on, 2 days off; 6 days on, 1 day off or continuous daily dosing) and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.	Accelerated Phase CML: BID Dosing at Study Entry Participants with accelerated phase CML were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). A TDD of 50 mg, 75 mg, 105 mg, 120 mg, 140 mg or 180 mg dasatinib was taken QD or split into 2 doses and taken BID (TDD of 50 mg, 70 mg, 100 mg, 140 mg, 180 mg or 240 mg). Participants were dosed on 1 of 3 schedules (5 days on, 2 days off; 6 days on, 1 day off or continuous daily dosing) and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.	Myeloid Blast Phase CML: BID Dosing at Study Entry Participants with myeloid blast phase CML were continued on the last dose and schedule of dasatinib that was received within the previous protocol CA180002 (NCT00064233). A TDD of 50 mg, 75 mg, 105 mg, 120 mg, 140 mg or 180 mg dasatinib was taken QD or split into 2 doses and taken BID (TDD of 50 mg, 70 mg, 100 mg, 140 mg, 180 mg or 240 mg). Participants were dosed on 1 of 3 schedules: 5 days on, 2 days off; 6 days on, 1 day off; or continuous daily dosing and were permitted to escalate or reduce by 1 dose level at a time, switch from QD dosing to BID dosing and vice versa provided they did not exceed a change of 1 dose level from the TDD. The weekly schedule was also permitted to be increased or decreased 1 level at a time.
Median Number of Months of Progression-free Survival (PFS) (Kaplan Meier Method)	32.0 months Interval 29.8 to Not reached. Upper limit of the confidence interval was not estimable because not enough subjects had progression event at the time of analysis.	—	—	—
