Abstract

The present invention provides therapeutic combinations featuring anti-CD73 antibodies (e.g., MEDI9447) and A2A receptor inhibitors and methods of using such combinations for reducing tumor-mediated immunosuppression.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of inhibiting tumor growth in a subject comprising administering an anti-CD73 antibody, or an antigen-binding fragment thereof, and an A2A receptor inhibitor for inhibiting tumor growth to the subject. 
     
     
         2 . A method of increasing an anti-tumor immune response comprising administering an anti-CD73 antibody, or an antigen-binding fragment thereof, and an A2A receptor inhibitor to a subject in need thereof. 
     
     
         3 . A method of treating a tumor in a subject comprising administering an anti-CD73 antibody, or an antigen-binding fragment thereof, and an A2A receptor inhibitor for treating a tumor to a subject. 
     
     
         4 . The method any one of  claims 1 - 3 , wherein the anti-CD73 antibody is MEDI9447 or an antigen-binding fragment thereof. 
     
     
         5 . The method of any one of  claims 1 - 3 , wherein the anti-CD73 antibody is Phen0203 hIgG1 or an antigen-binding fragment thereof. 
     
     
         6 . The method of any one of  claims 1 - 3 , wherein the A2A receptor inhibitor is SCH58261. 
     
     
         7 . The method of any one of  claims 1 - 3 , wherein the anti-CD73 antibody is MEDI9447 or an antigen-binding fragment thereof and the A2A receptor inhibitor is SCH58261. 
     
     
         8 . The method of any one of  claims 1 - 3 , wherein the anti-CD73 antibody is Phen0203 hIgG1 or an antigen-binding fragment thereof and the A2A receptor inhibitor is SCH58261. 
     
     
         9 . The method of any one of  claims 1 - 3 , wherein the anti-CD73 antibody or antigen-binding fragment thereof and the adenosine receptor inhibitor (A2ARi) are administered concurrently. 
     
     
         10 . The method of any one of  claims 1 - 3 , wherein the anti-CD73 antibody or antigen-binding fragment thereof is administered prior to the adenosine receptor inhibitor (A2ARi). 
     
     
         11 . The method of any one of  claims 1 - 3 , wherein the adenosine receptor inhibitor (A2ARi) is administered prior to the anti-CD73 antibody or antigen-binding fragment thereof. 
     
     
         12 . The method of any one of  claims 1 - 3 , wherein the tumor is a breast cancer, hormonally mediated breast cancer, triple negative breast cancer, colon carcinoma, colorectal cancer, lung cancer, melanoma, non-small cell carcinoma, lymphoma, Hodgkin's and non-Hodgkin's lymphoma, Burkitt's lymphoma, and sarcoma. 
     
     
         13 . The method of any one of  claims 1 - 3 , wherein said method results in an increase in overall survival as compared to the administration of any one of the anti-CD73 antibody or the A2A receptor inhibitor alone. 
     
     
         14 . The method of any one of  claims 1 - 3 , wherein the said method induces or increases a tumor-specific immune response. 
     
     
         15 . The method of any one of  claims 1 - 3 , wherein the said method reduces the immunosuppressive effects of a AMP/CD73/adenosine pathway. 
     
     
         16 . The method of any one of  claims 1 - 3 , wherein the said method reduces metastasis or reduces the propensity of the tumor to metastasize relative to the administration of either the anti-CD73 antibody or the adenosine receptor inhibitor (A2ARi) alone. 
     
     
         17 . The method of any one of  claims 1 - 3 , wherein the said method reduces the number of metastases within the subject. 
     
     
         18 . The method of any one of  claims 1 - 3 , wherein the subject is a human patient. 
     
     
         19 . The method of any one of  claims 1 - 3 , wherein the tumor is a CD73 overexpres sing tumor. 
     
     
         20 . The method of any one of  claims 1 - 3 , wherein the cancer has a prometastatic phenotype. 
     
     
         21 . A kit for increasing anti-tumor activity, the kit comprising an anti-CD73 antibody or antigen-binding fragment thereof and an A2A receptor inhibitor. 
     
     
         22 . The kit of  claim 21 , wherein the anti-CD73 antibody is MEDI9447 or an antigen-binding fragment thereof. 
     
     
         23 . The kit of  claim 21 , wherein the anti-CD73 antibody is Phen0203 hIgG1 or an antigen-binding fragment thereof. 
     
     
         24 . The kit of  claim 21 , wherein the A2A receptor inhibitor is SCH58261. 
     
     
         25 . The kit of  claim 21 , wherein the anti-CD73 antibody is MEDI9447 or an antigen-binding fragment thereof and the A2A receptor inhibitor is SCH58261. 
     
     
         26 . The kit of  claim 21 , wherein the anti-CD73 antibody is Phen0203 hIgG1 or an antigen-binding fragment thereof and the A2A receptor inhibitor is SCH58261. 
     
     
         27 . A pharmaceutical formulation comprising an effective amount an anti-CD73 antibody or antigen-binding fragment thereof and an A2A receptor inhibitor. 
     
     
         28 . The pharmaceutical formulation of  claim 27 , wherein the anti-CD73 antibody is MEDI9447 or an antigen-binding fragment thereof. 
     
     
         29 . The pharmaceutical formulation of  claim 27 , wherein the anti-CD73 antibody is Phen0203 hIgG1 or an antigen-binding fragment thereof. 
     
     
         30 . The pharmaceutical formulation of  claim 27 , wherein the A2A receptor inhibitor is SCH58261.
