	Description
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). 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.

^[1]	The ECOG PS is used to assess disease severity, with 0 being the least severe score and 5 being the most severe score. A score of 0 is fully active; 1 is restricted physically strenuous activity; 2 is ambulatory but unable to work; 3 is capable of only limited self care; 4 is completely disabled; 5 is dead.

Certain Agreements:

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: Bristol-Myers Squibb Co. agreements with investigators vary; constant is our right to embargo communications regarding trial results prior to public release for a period ≤60 days from submittal for review. We will not prohibit investigators from publishing, but will prohibit the disclosure of previously undisclosed confidential information other than study results, and request postponement of single-center publications until after disclosure of the clinical trial's primary publication.
