Of the 10 patients, 60% experienced adverse events, including one grade 3 increase in gamma-glutamyltransferase. In conclusion, ONA-XR showed early tumor proliferation suppression, particularly in high PgR-expressing tumors, supporting its potential for further clinical evaluation.

In vivo, ACC-bearing mice were treated with immune checkpoint inhibitors and mifepristone...Moreover, the percentage of macrophages detected by immunohistochemistry positively correlated with response to immunotherapy. Collectively, this study identifies a glucocorticoid-induced C1Q+ CD163 + macrophage phenotype that may contribute to T cell recruitment and enhance the efficacy of immunotherapy in ACC.

These findings demonstrate that M. longistyla extract possesses significant anti-hemorrhagic activity evidenced by reduced uterine bleeding, suppression of pro-inflammatory cytokine (TNF-α) and upregulation of VEGF. These effects suggest that the extract promotes endometrial repair and restoration of uterine homeostasis.

Short-term mifepristone exposure does not produce molecular changes linked to endometrial carcinogenesis in BRCA1/2 pathogenic variant carriers. These findings provide important safety data for the future development of progesterone receptor modulators in cancer prevention. Long-term studies are needed to confirm these observations.

The study found that mifepristone treatment significantly reduced serum CA125 and PRL levels, and the 20 mg/kg/day dose was most effective in improving pregnancy outcomes. These findings suggest that mifepristone can reduce key biomarkers associated with uterine adenomyosis and improve fertility outcomes, offering a promising treatment option for women suffering from this condition.

Current treatment involves surgery, radiotherapy and chemotherapy (temozolomide), but survival rates remain low. Repurposing mifepristone (MF), a contraceptive drug, shows promise for GB treatment, warranting further study...The pilot trial demonstrated the pharmacological safety of using MF as an adjuvant in GB treatment. Patients treated with MF showed a significant increase in survival, with an 80% survival rate at 1 year compared to 0% in those who were treated with the standard treatment.

The likelihood of this type of response occurring by chance is extremely low. It is hoped that this report will encourage oncologists, scientists, and clinicians to further investigate the use of SPRMs in a larger cohort of patients with stage IV lung cancer, and potentially in those with less advanced disease.
