Abstract
Methods for determining the likelihood that a subject suffering from a solid tumor cancer will benefit from treatment with an illudin are disclosed herein. Further, there are also methods for treatment based on such determination. In several embodiments, markers prostaglandin reductase 1 (PTGR1), Protein Tyrosine Phosphatase Non-Receptor Type 14 (PTPN14), Aspartate Beta-Hydroxylase (ASPH) together with one or more genes or alone may be used to enhance or guide treatment with an illudin. In certain embodiments, the protein or gene may be expressed or methylated.
Claims16
A method of treating solid tumor cancer in a human subject with a targeted drug therapy comprising:
- extracting a biological sample from the human subject;
- measuring the level of expression of PTGR1, PTPN14, ASPH or combination thereof in the biological sample;
- identifying a patient having cancer sensitive to treatment with an illudin-based anti-cancer agent;
- treating the human subject with the illudin-based anti-cancer agent having the following structure:
- wherein the expression level in the human subject of PTGR1, PTPN14, or ASPH is greater than the level in human without the solid tumor cancer.
A method of treating solid tumor cancer with a targeted drug therapy comprising:
- identifying a patient having cancer sensitive to treatment with a compound of the formula:
- wherein R1, R2 and R3 are independently (C1-C4) alkyl, methyl, or hydroxyl
- measuring the level of expression of PTGR1 of a combination thereof in the biological sample.
A method for predicting response lent in a patient having a solid tumor, comprising:
- obtaining a biological sample from the patient;
- measuring the level of expression of PTGR1, PTPN 14, ASPH or a combination thereof in the biological sample;
- and
- comparing the level of expression in the biological sample to that of a biological sample from a subject not having a solid cancer;
- wherein an increased level of the expression in the biological sample from the patient relative to that from the subject not having the solid tumor indicates a likelihood of an effective response to the treatment with a compound of the formula:
- or a pharmaceutically acceptable salt, solvate or stereoisomer thereof.
A kit for determining whether an anti-cancer effect is likely to be produced in a cancer by an illudin, comprising a means for determining the level of PTGR1, PTPN14, ASPH or a combination thereof expression in a cancer relative to a normal value from biological sample from the patient relative to that from the subject having the solid tumor.
The method of claim 16, wherein the cancer is colorectal cancer, pancreatic cancer, primary liver cancers, kidney cancer, ovarian cancer, uterine cancer, lung cancer, breast cancer, prostate cancer, sarcomas, or adipose tissue cancer.
The kit of claim 18, wherein the illudin has
