BACKGROUND: Triple-negative breast cancers have inherent defects in DNA repair, making this cancer a rational target for therapy based on poly(adenosine diphosphate-ribose) polymerase (PARP) inhibition. METHODS: We conducted an open-label, phase 2 study to compare the efficacy and safety of gemcitabine and carboplatin with or without iniparib, a small molecule with PARP-inhibitory activity, in patients with metastatic triple-negative breast cancer. A total of 123 patients were randomly assigned to receive gemcitabine (1000 mg per square meter of body-surface area) and carboplatin (at a dose equivalent to an area under the concentration-time curve of 2) on days 1 and 8 - with or without iniparib (at a dose of 5.6 mg per kilogram of body weight) on days 1, 4, 8, and 11 - every 21 days. Primary end points were the rate of clinical benefit (i.e., the rate of objective response [complete or partial response] plus the rate of stable disease for ≥6 months) and safety. Additional end points included the rate of objective response, progression-free survival, and overall survival. RESULTS: The addition of iniparib to gemcitabine and carboplatin improved the rate of clinical benefit from 34% to 56% (P = 0.01) and the rate of overall response from 32% to 52% (P = 0.02). The addition of iniparib also prolonged the median progression-free survival from 3.6 months to 5.9 months (hazard ratio for progression, 0.59; P = 0.01) and the median overall survival from 7.7 months to 12.3 months (hazard ratio for death, 0.57; P = 0.01). The most frequent grade 3 or 4 adverse events in either treatment group included neutropenia, thrombocytopenia, anemia, fatigue or asthenia, leukopenia, and increased alanine aminotransferase level. No significant difference was seen between the two groups in the rate of adverse events. CONCLUSIONS: The addition of iniparib to chemotherapy improved the clinical benefit and survival of patients with metastatic triple-negative breast cancer without significantly increased toxic effects. On the basis of these results, a phase 3 trial adequately powered to evaluate overall survival and progression-free survival is being conducted. Copyright © 2011 Massachusetts Medical Society.

The present invention relates to methods of identifying a disease treatable with PARP modulators by identifying a level of PARP in a sample of a subject, making a decision regarding identifying the disease treatable by the PARP modulators wherein the decision is made based on the level of PARP. The method further comprises of treating the disease in the subject with the PARP modulators. The methods relate to identifying up-regulated PARP in a disease and making a decision regarding the treatment of the disease with PARP inhibitors. The extent of PARP up-regulation in a disease can also help in determining the efficacy of the treatment with PARP inhibitors. The present invention also relates to methods of identifying a disease treatable with PARP modulators by identifying a level of PARP in a plurality of samples from a population, making a decision regarding identifying the disease treatable by the PARP modulators wherein the decision is made based on the level of PARP. The method further comprises of treating the disease in a subject population with the PARP modulators. The methods relate to identifying up-regulated PARP in a disease and making a decision regarding the treatment of the disease with PARP inhibitors. The extent of PARP up-regulation in a disease can also help in determining the efficacy of the treatment with PARP inhibitors. The present invention discloses various diseases that have up-regulated or down-regulated PARP and can be treated with PARP inhibitors or PARP activators, respectively. The examples of the diseases include cancer, inflammation, metabolic disease, CVS disease, CNS disease, disorder of hematolymphoid system, disorder of endocrine and neuroendocrine, disorder of urinary tract, disorder of respiratory system, disorder of female reproductive system, and disorder of male reproductive system.


The present invention relates to a method of treating a fatty acid synthesis related disease comprising administering to a patient in need thereof an effective amount of a PARP inhibitor or metabolite thereof to inhibit fatty acid synthesis, wherein the fatty acid synthesis related disease is obesity, diabetes, or cardiovascular disease. The present invention also relates to a method of treating a cancer in a subject comprising: (i) identifying a level of fatty acid in a sample from the subject, and (ii) administering an effective amount of a PARP inhibitor or metabolite thereof to inhibit fatty acid synthesis in the subject, wherein the administration is based on the level of fatty acid, thereby treating the cancer in the subject. The present invention further relates to a method of treating Her-2 related cancers by administering to a patient in need thereof an effective amount of a PARP inhibitor or metabolite thereof to inhibit fatty acid synthesis.
