Methods and compositions for treating liquid tumors
View Patent ↗The application relates to a method of using compositions having anti-alpha-4 integrin and/or anti-alpha-9 integrin activity to inhibit liquid tumor growth, malignancies thereof and/or development of metastases thereof that involve expression of an alpha-4 integrin and/or alpha-9 integrin. Pharmaceutical compositions and combination therapies (for example, with chemotherapies) for the inhibition of liquid tumor growth, malignancies thereof and/or development of metastases thereof are also provided.
1. A method for inhibiting liquid tumor growth, malignancies thereof and/or development of metastases thereof comprising administering a therapeutically effective amount of a conjugate of formula XXII below:
wherein x, y, and z are independently an integer such that the aggregate of x, y, and z is about 100 to 1360.
2. The method of claim 1 , wherein x, y, and z are independently an integer such that the conjugate of formula XXII has a molecular weight of about 40-45 kDa.
3. The method of claim 1 , wherein the malignancy is a hematological malignancy.
4. The method of claim 3 , wherein the hematological malignancy is a leukemia or multiple myeloma.
5. The method of claim 4 , wherein the leukemia is selected from the group consisting of acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), and chronic lymphocytic leukemia (CLL).
6. A pharmaceutical composition for inhibiting liquid tumor growth, malignancies thereof and/or development of metastases thereof in a patient in need thereof, comprising a therapeutically effective amount of a conjugate of formula XXII of claim 1 , or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier, vehicle, or diluent.
7. A combination therapy for inhibiting tumor growth, malignancies and/or metastatic progression and/or development of metastases comprising administering a conjugate of formula XXII of claim 1 and a chemotherapeutic, and immunotherapeutic, and/or radiation therapy.
