Antagonizing TGF-beta activity with various ectodomains TGF-beta receptors used in combination or as fusion proteins
View Patent ↗Anti-cancer agents and/or transforming growth factor beta (TGF-beta or TGFβ) antagonists are disclosed, where the agents and/or antagonists include a therapeutically effective amount of a combination of therapeutically active portions of sRII and therapeutically active portions of sRIII or a fusion polypeptide or protein comprising therapeutically active portions of sRII and therapeutically active portions of sRIII. Methods for preventing, treating and/or ameliorating the symptoms of cancer are also disclosed based on administering an effective amount of a composition of this invention.
1. A pharmaceutical composition comprising a therapeutically effective amount of a mixture of:
(a) a soluble type II receptor (sRII) which comprises (i) the extracellular domain of the TGFβ type II receptor or (ii) SEQ ID NO: 2; and
(b) a soluble type III receptor (sRIII) which comprises SEQ ID NO: 4.
2. The composition of claim 1 , wherein the composition comprises a soluble type II receptor which comprises SEQ ID NO:2.
3. The composition of claim 1 , wherein the soluble type II receptor is the extracellular domain of the TGFβ type II receptor.
4. The composition of claim 2 , wherein the soluble type II receptor consists of SEQ ID NO: 2.
5. The composition of claim 1 , wherein the soluble type III receptor consists of SEQ ID NO: 4.
6. The composition of claim 5 , wherein the soluble type II receptor consists of SEQ ID NO: 2.
7. A pharmaceutical composition comprising a therapeutically effective amount of SEQ ID NO: 4.
8. The composition of claim 7 , wherein the composition further comprises a therapeutically effective amount of SEQ ID NO:2.
