Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Subjects will be orally administrated SKLB1028 twice daily over continuous 28-day cycles . Subjects in the salvage chemotherapy group will receive chemotherapy as required by the guidelines. Subjects receiving SKLB1028, LoDAC, or azacytidine will continue to receive the treatment until a treatment discontinuation criterion is met. Subjects receiving HAA or FLAG will take 1 cycle of therapy and will be assessed for response after the 1st cycle. After the efficacy evaluation, the subject may receive a second cycle of chemotherapy at the investigator's discretion. will receive the second cycle of chemotherapy.
Subjects who have a donor identified and with complete remission after treatment may undergo hematopoietic stem cell transplant (HSCT) without leaving the study. Subjects in the salvage chemotherapy group who withdrew due to non-response to treatment or disease progression, could switch to SKLB1028 if SKLB1028 will likely benefit the patient at the investigator's discretion.

Study Groups

SKLB1028
Subjects will receive 150 mg orally twice daily (BID) in continuous 28-day cycles
SKLB1028
SKLB1028 will be administered by oral capsules, 150 mg twice daily (BID).
Salvage Chemotherapy
Chemotherapy will be given in 28-day cycles. Subjects on low-dose cytarabine (LoDAC) will receive 10 to 20 mg of cytarabine twice daily by subcutaneous (SC) or intravenous (IV) injections for 7 to 14 days.
Subjects on azacitidine will receive 75 mg/m\^2 daily by SC or IV, for 5 to 7 days.
Subjects on homoharringtonine (HHT), cytarabine and aclarubicin (HAA) will receive 2 mg/m\^2 of HHT by IV, for 7 days (day 1 to 7) (or HHT 2 mg/m\^2, twice daily, day 1 to 3); 100\~200 mg/m\^2 of cytarabine by IV for 7 days (day 1\~7) and 20 mg/d of aclarubicin by IV for 7 days (day 1 to 7).
Subjects on fludarabine, cytarabine and granulocyte colony-stimulating factor (G-CSF) (FLAG) will receive 30 mg/m\^2 of fludarabine daily by IV for 5 days (day 2 to 6), 1000\~2000 mg/m2 of cytarabine daily by IV for 5 days (day 2 to 6), and 300 g/m\^2 of G-CSF daily by SC or IV for 5 days (days 1 to 5). After completion of chemotherapy, G-CSF will be administered continually until ANC\>0.5 x 10\^9 / L.
Salvage Chemotherapy
Low-dose cytarabine (LoDAC); azacytidine; homoharringtonine (HHT), cytarabine and aclarubicin (HAA) or fludarabine, cytarabine and granulocyte colony-stimulating factor (FLAG) will be administered by subcutaneous (SC) and/or intravenous (IV) injections.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Age≥18 years old, no gender limitation.
3. Patient has a diagnosis of primary AML or AML secondary to myelodysplastic syndrome (MDS) as determined by pathological and morphological results, according to World Health Organization (WHO) 2016 classification.
4. Patient is refractory to or relapsed after first-line AML therapy (with or without HSCT).
1. Refractory to first-line AML treatment is defined as: the patient did not achieve complete remission/complete remission with incomplete hematologic recovery/complete remission with incomplete platelet recovery (CR/CRi/CRp) under initial therapy. A patient eligible for standard therapy must receive at least 1 cycle of an anthracycline containing induction therapy in the standard dose for the selected induction regimen. A patient not eligible for standard therapy must have received at least 1 complete block of induction therapy seen as the optimum choice of therapy to induce remission for this patient as per investigator's assessment.
2. Early relapse after first-line AML therapy is defined as: the patients achieved CR/CRi/CRp after first-line treatment, and relapsed within 6 months with hematological relapse.
3. Advanced relapse after first-line AML therapy is defined as: the patients achieved CR/CRi/CRp after first-line treatment and relapsed after 6 months with hematological relapse;
5. Patient is positive for FLT3 mutation in bone marrow or whole blood.
6. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
7. Patient is eligible for pre-selected salvage chemotherapy according to investigator assessment.
