| Group 1 | Stratum 1 With 50 mg/m^2 | Patients known to be CNS3 at study entry may receive ITT on Day 1 rather than IT ARAC. | 4 | 6 | OG000 |
| Group 2 | Stratum PK With 50 mg/m^2 | Patients known to be CNS3 at study entry may receive ITT on Day 1 rather than IT ARAC. | 1 | 6 | OG001 |

- Description
Frequency (%) of patients with at least partial response to Palbociclib per leukemia/lymphoma specific response criteria: Complete Response (CR), M1 marrow (\<5% blasts) and absolute neutrophil count (ANC) at least 500/uL and platelet count at least 50000/uL without transfusion for 7 days; Complete response with incomplete recovery (CRi), M1 marrow (\<5% blasts), ANC\<500uL, platelet count \<50,000uL; Partial Response (PR), Complete disappearance of circulating blasts and achievement of M2 marrow status if M3 originally, without new sites of extramedullary disease, and with ANC ≥ 500/µL. Complete response in the marrow without resolution of extramedullary sites. Overall Response (OR) = CR+CRi+PR
