Abstract

The present disclosure is directed to the use of mithramycin analogues to treat cancers having mutations in the SWI/SNF pathway, such as rhabdoid cancers with mutations in SMARCB1.

Claims (16)

1 . A method of treating a subject having a rhabdoid cancer or a breast cancer that exhibits a mutation in the SWI-SNF pathway comprising:

(a) determining, prior to treating, that said subject has a SMARCB1-mutated cancer; and

(b) administering to said subject a EC-8042.

2 . The method of claim 1 , further comprising treating said subject with a second cancer therapy.

3 . The method of claim 2 , wherein said second cancer therapy is chemotherapy, radiotherapy, immunotherapy, hormonal therapy, toxin therapy or surgery.

4 . The method of claim 1 , wherein the rhabdoid cancer or breast cancer exhibits a mutation in SMARCB1.

5 . The method of claim 1 , wherein determining comprises:

(a) obtaining a cancer tissue sample from said subject that contains protein and/or nucleic acids; and

(b) determining mutation status of an SMARCB1 protein or nucleic acid encoding SMARCB1 in said sample.

6 . The method of claim 5 , wherein determining comprises a nucleic acid-based assay.

7 . The method of claim 5 , wherein determining comprises a protein-based assay.

8 . The method of claim 1 , wherein said subject is a human subject.

9 . The method of claim 1 , wherein said subject is a non-human primate.

10 . The method of claim 1 , wherein said subject has previously been diagnosed with a rhabdoid cancer or a breast cancer.

11 . The method of claim 1 , wherein said rhabdoid cancer or breast cancer is recurrent, primary, metastatic or multi-drug resistant.

12 . The method of claim 1 , wherein EC-8042 is administered more than once.
