Methods and materials for treating hematological malignancies
View Patent ↗This document provides methods and materials involved in treating hematological malignancies. For example, methods and materials for using telomerase inhibitors to treat hematological malignancies such as hematological malignancies with a spliceosome mutation genotype or presenting with ringed sideroblasts within bone marrow are provided.
1. A method for treating myelofibrosis with an increased likelihood of success, wherein said method comprises administering imetelstat or imetelstat sodium to a human identified as having myelofibrosis with the presence of hematological malignancy cells comprising a somatic mutation in SF3B1, U2AF1, or SRSF2 nucleic acid, wherein said myelofibrosis is treated with an increased likelihood of success compared to treating myelofibrosis in a comparable human lacking somatic mutations in SF3B1, U2AF1, and SRSF2 nucleic acid, wherein said somatic mutation in SF3B1 nucleic acid results in an H662Q, K666E, or K700E mutation, wherein said somatic mutation in U2AF1 nucleic acid results in an S34Y, S34F, Q157P, or 469_insAGTATG mutation, and wherein said somatic mutation in SRSF2 nucleic acid results in a P95H, P95L, P95R, P95A, or P95T mutation.
2. The method of claim 1 , wherein said method comprises administering imetelstat sodium to said human.
3. A method for treating myelofibrosis with an increased likelihood of success, wherein said method comprises administering imetelstat or imetelstat sodium to a human identified as having myelofibrosis with hematological malignancy cells comprising a germline ASXL1 genotype for said human, wherein said myelofibrosis is treated with an increased likelihood of success compared to treating myelofibrosis in a comparable human having a somatic mutation in ASXL1 nucleic acid.
4. The method of claim 3 , wherein said method comprises administering imetelstat sodium to said human.
5. The method of claim 3 , wherein said human is a human identified as having myelofibrosis with the presence of hematological malignancy cells comprising a somatic mutation in SF3B1, U2AF1, or SRSF2 nucleic acid, wherein said somatic mutation in SF3B1 nucleic acid results in an H662Q, K666E, or K700E mutation, wherein said somatic mutation in U2AF1 nucleic acid results in an S34Y, S34F, Q157P, or 469 insAGTATG mutation, and wherein said somatic mutation in SRSF2 nucleic acid results in a P95H, P95L, P95R, P95A, or P95T mutation.
6. A method for identifying and treating a human having myelofibrosis with an increased likelihood of success, wherein said method comprises:
(i) detecting the presence of hematological malignancy cells comprising a somatic mutation in SF3B1, U2AF1, or SRSF2 nucleic acid within said human, and
(ii) administering imetelstat or imetelstat sodium to said human, wherein said myelofibrosis is treated with an increased likelihood of success compared to treating myelofibrosis in a comparable human lacking somatic mutations in SF3B1, U2AF1, and SRSF2 nucleic acid,
wherein said somatic mutation in SF3B1 nucleic acid results in an H662Q, K666E, or K700E mutation, wherein said somatic mutation in U2AF1 nucleic acid results in an S34Y, S34F, Q157P, or 469_insAGTATG mutation, and wherein said somatic mutation in SRSF2 nucleic acid results in a P95H, P95L, P95R, P95A, or P95T mutation.
7. The method of claim 6 , wherein said method comprises detecting that said hematological malignancy cells comprise a germline ASXL1 genotype for said human.
