Methods of treating cancer in pediatric patients
Provided herein are methods for treating cancers (e.g., inflammatory myofibroblastic tumor, anaplastic large cell lymphoma, and neuroblastoma) in pediatric patients using brigatinib, as monotherapy or combination therapy with one or more second therapeutic agents.
1. A method for treating a cancer in a pediatric patient having the cancer, comprising administering to the patient a therapeutically effective amount of Compound A of the formula:
or a pharmaceutically acceptable salt thereof, wherein the cancer is inflammatory myofibroblastic tumor (IMT), anaplastic large cell lymphoma (ALCL), or neuroblastoma.
2. The method of claim 1 , wherein the cancer is anaplastic lymphoma kinase positive (ALK+).
3. The method of claim 1 or 2 , wherein the cancer is IMT or ALCL.
4. The method of claim 1 or 2 , wherein the cancer is neuroblastoma.
5. The method of claim 1 or 2 , wherein the cancer is IMT.
6. The method of claim 5 , wherein the IMT is unresectable or recurrent IMT.
7. The method of claim 1 or 2 , wherein the cancer is ALCL.
8. The method of claim 7 , wherein the ALCL is relapsed or refractory ALCL.
9. The method of claim 7 , wherein the ALCL is newly diagnosed ALCL.
10. The method of claim 9 , wherein the ALCL is newly diagnosed ALCL with high risk for recurrence.
11. The method of claim 10 , wherein the high risk for recurrence is characterized by minimal disseminated disease positive (MDD+) at diagnosis or anti-ALK antibody titer ≤ 1/750 at diagnosis.
12. The method of claim 1 or 2 , wherein Compound A, or a pharmaceutically acceptable salt thereof, is administered orally.
13. The method of claim 12 , wherein Compound A, or a pharmaceutically acceptable salt thereof, is administered once a day (QD).
14. The method of claim 13 , wherein Compound A, or a pharmaceutically acceptable salt thereof, is administered at a dose of from about 30 mg/m 2 to about 100 mg/m 2 .
15. The method of claim 14 , wherein Compound A, or a pharmaceutically acceptable salt thereof, is administered at a dose of about 30, about 40, about 50, about 60, about 70, about 80, about 90, or about 100 mg/m 2 .
16. The method of claim 1 or 2 , further comprising administering to the patient a therapeutically effective amount of a one or more additional second therapeutic agents.
17. The method of claim 16 , wherein the one or more additional therapeutic agents comprises cyclophosphamide, doxorubicin, vincristine, corticosteroid, ifosfamide, etoposide, methotrexate, or cytarabine, or a combination thereof.
18. The method of claim 17 , wherein the corticosteroid is dexamethasone or hydrocortisone, or a combination thereof.
19. The method of claim 16 , wherein the one or more additional therapeutic agents comprises dexamethasone, which is administered at a dose of from about 5 mg/m 2 to about 10 mg/m 2 .
20. The method of claim 16 , wherein the one or more additional therapeutic agents comprises cyclophosphamide, which is administered at a dose of about 200 mg/m 2 .
21. The method of claim 16 , wherein the one or more additional therapeutic agents comprises ifosfamide, which is administered at a dose of about 800 mg/m 2 .
22. The method of claim 16 , wherein the one or more additional therapeutic agents comprises methotrexate, which is administered at a dose of about 3 g/m 2 .
23. The method of claim 16 , wherein the one or more additional therapeutic agents comprises etoposide, which is administered at a dose of about 100 mg/m 2 .
24. The method of claim 16 , wherein the one or more additional therapeutic agents comprises cytarabine, which is administered at a dose of about 150 mg/m 2 and is administered twice a day.
25. The method of claim 16 , wherein the one or more additional therapeutic agents comprises doxorubicin, which is administered at a dose of about 25 mg/m 2 .
26. The method of claim 16 , wherein Compound A, or a pharmaceutically acceptable salt thereof, and the one or more additional therapeutic agents are administered for one or more 21 days cycles.
27. The method of claim 26 , wherein Compound A, or a pharmaceutically acceptable salt thereof, is administered on days 1-21 of the 21 days cycle.
28. The method of claim 27 , wherein the one or more additional therapeutic agents comprises dexamethasone, which is administered on days 1-5 of the 21 days cycle.
29. The method of claim 27 , wherein the one or more additional therapeutic agents comprises cyclophosphamide, which is administered on days 1 and 2 of the 21 day cycle.
30. The method of claim 27 , wherein the one or more additional therapeutic agents comprises cyclophosphamide, which is administered on days 1-5 of the 21 day cycle.
31. The method of claim 27 , wherein the one or more additional therapeutic agents comprises a combination of hydrocortisone, methotrexate, and cytarabine, which are administered on day 1 of the 21 days cycle.
32. The method of claim 27 , wherein the one or more additional therapeutic agents comprises ifosfamide, which is administered on days 1-5 of the 21 days cycle.
33. The method of claim 27 , wherein the one or more additional therapeutic agents comprises methotrexate, which is administered on day 1 of the 21 days cycle.
34. The method of claim 27 , wherein the one or more additional therapeutic agents comprises etoposide, which is administered on days 4 and 5 of the 21 days cycle.
35. The method of claim 27 , wherein the one or more additional therapeutic agents comprises cytarabine, which is administered on days 4 and 5 of the 21 days cycle.
36. The method of claim 27 , wherein the one or more additional therapeutic agents comprises doxorubicin, which is administered on days 4 and 5 of the 21 days cycle.
