Clinical Trial Summary

This protocol will allow ponatinib with refractory Chronic Myeloid Leukemia or Ph+ Acute Lymphoblastic Leukemia

15. Are pregnant or lactating.

16. Underwent major surgery (with the exception of minor surgical procedures, such as catheter placement or BM biopsy) within 14 days prior to first dose of Ponatinib.

17. Infectious diseases test showed anti-HIV (+) or anti-HCV (+) or HbsAg (+) or TP (+).

18. Suffer from any condition or illness that, in the opinion of the investigator, would compromise patient safety or interfere with the evaluation of the safety of the study drug.

19. Have hypertension (diastolic blood pressure = 90 mmHg and/or systolic blood pressure = 140 mm Hg).

20. Taken herbal preparations or related over-the-counter preparations containing Chinese herbal ingredients within 2 weeks prior to the first dose of Ponatinib.

21. Any subject who is not suitable for the study in the opinion of the investigator.

For AP/BP-CML and ALL patients:

1. Received TKI therapy within 7 days prior to receiving the first dose of Ponatinib, or have not recovered (> grade 2 by NCI CTCAE v.5.0) from AEs (except alopecia) due to agents previously administered.

2. Received other therapies (excluding hydroxyurea) as follows:

For AP-CML patients, received interferon, cytarabine, or immunotherapy within 14 days, or any other cytotoxic chemotherapy, radiotherapy, or investigational therapy within 28 days prior to receiving the first dose of Ponatinib. For BP-CML patients, received chemotherapy within 7 days prior to the first dose of Ponatinib. Otherwise, 2a applies. For Ph+ ALL patients, received corticosteroids within 24 hours before the first dose of Ponatinib; otherwise, 2a applies.

3. Underwent autologous or allogeneic stem cell transplant < 60 days prior to receiving the first dose of Ponatinib.

4. Take medications that are known to be associated with Torsades de Pointes or QT interval prolongation.

5. Require concurrent treatment with immunosuppressive agents, other than corticosteroids prescribed for a short course of therapy.

6. Have previously been treated with Ponatinib or its analogues (including drug substance).

7. Patients with AP-CML, BP-CML, or Ph+ ALL are excluded if they are in MaHR.

8. Patients with AP-CML, BP-CML, or Ph+ ALL are excluded if a baseline BM aspirate adequate for cell count and differential report is not available.

9. Have active central nervous system (CNS) disease as evidenced by cytology or pathology for AP-CML, BP-CML, or Ph+ ALL.

10. Have significant, uncontrolled, or active cardiovascular disease.
