Suggested thresholds defining failure, suboptimal response, and optimal response.

	3 Months	6 Months	12 Months	18 Months
Failure	No hematologic response	> 95% Ph⁺	> 35% Ph⁺	> 0% Ph⁺
Suboptimal Response	No complete hematologic response	35–95% Ph⁺	1–35% Ph⁺	0% Ph⁺, < 3 log ⇓ in BCR-ABL transcripts
Optimal response	1–2 log ⇓ in BCR-ABL transcripts	< 35% Ph⁺	0% Ph+, ≥ 3 log ⇓ in BCR-ABL transcripts	0% Ph⁺, ≥ 3 log ⇓ in BCR-ABL transcripts
