The Ataxia telangiectasia and Rad3-related protein (ATR) is a human serine/threonine protein kinase involved in DNA repair. ATR is activated upon detection of single stranded DNA breaks, and activates the DNA damage checkpoint.
DNA damage and repair (DDR) inhibitors, such as ATR inhibitors, show promise in cancer therapy. However, a problem in cancer therapy is the emergence of resistance to these inhibitors. Cancer progression due to evasion of anti-cancer immune response contributes to cancer progression and to morbidity and mortality in patients with cancer. There is a need in the art for new therapies that avoid or reduce resistance to DDR inhibitors.

The present disclosure provides, for instance, methods of treating cancer. In some embodiments, the cancer is a solid tumor. In some embodiments, the cancer is chosen from chosen from breast cancer, ovarian cancer, pancreatic cancer, fallopian tube cancer, primary peritoneal cancer, or prostate cancer.
In some embodiments, at the time of treatment, the subject has, or is identified as having, stable disease or progressive disease. The therapies can be administered during periods of active disorder, or during a period of remission or less active disease. The first therapy can be administered before the second therapy, concurrently with the treatment, post-treatment, or during remission of the disorder. In some embodiments, after the treatment described herein, the subject experiences a partial response, a complete response and/or prolonged response or delayed relapse (e.g., compared to the expected course of disease when treated without the treatment described herein).
In some embodiments, the subject is or is identified as being, at risk of developing resistance to, or at risk of being refractory to, a DDR inhibitor. In some embodiments, the subject is initially responsive to the DDR inhibitor, but then becomes resistant or refractory during the course of treatment with the DDR inhibitor. In some embodiments, the subject was resistant or refractory at the outset of DDR inhibitor treatment.
In some embodiments, the subject expresses GDF15, e.g., expresses a detectable amount of GDF15. In some embodiments, the tumor expresses GDF15, e.g., expresses a detectable amount of GDF15.
In some embodiments, when administered in combination, one or both of the DDR inhibitor and the GDF15 inhibitor, may be administered in an amount or dose that is higher, lower or the same than the amount or dosage of each agent used individually, e.g., as a monotherapy. In some embodiments, when administered in combination, one or both of the DDR inhibitor and the GDF15 inhibitor, may be administered with a duration that is longer, shorter, or the same than the duration of each agent used individually, e.g., as a monotherapy.
The administration of the compositions described herein may be carried out in any convenient manner, including by aerosol inhalation, injection, ingestion, transfusion, implantation or transplantation. The compositions described herein may be administered to a patient orally, trans-arterially, subcutaneously, intradermally, intratumorally, intranodally, intramedullary, intramuscularly, by intravenous (i.v.) injection, or intraperitoneally.
In some embodiments, the combination therapies described herein result in a synergistic effect. In some embodiments, the combination therapies described herein result in an additive effect.
In some embodiments, two (or more) different treatments are delivered to the subject in combination, during the course of the subject's affliction with the disorder, e.g., the two or more treatments are delivered after the subject has been diagnosed with the disorder and before the disorder has been cured or eliminated or treatment has ceased for other reasons. In some embodiments, the delivery of one treatment is still occurring when the delivery of the second begins, so that there is overlap in terms of administration. This is sometimes referred to herein as “simultaneous” or “concurrent delivery”. In other embodiments, the delivery of one treatment ends before the delivery of the other treatment begins. In some embodiments of either case, the treatment is more effective because of combined administration. For example, the second treatment is more effective, e.g., an equivalent effect is seen with less of the second treatment, or the second treatment reduces symptoms to a greater extent, than would be seen if the second treatment were administered in the absence of the first treatment, or the analogous situation is seen with the first treatment. In some embodiments, delivery is such that the reduction in a symptom, or other parameter related to the disorder is greater than what would be observed with one treatment delivered in the absence of the other. The effect of the two treatments can be partially additive, wholly additive, or greater than additive. The delivery can be such that an effect of the first treatment delivered is still detectable when the second is delivered.
