Exemestane 25 MG

This is an international, multi-center, randomised, open label, superiority phase III trial of elacestrant vs standard endocrine therapy in patients with ER+/HER2- breast cancer and ctDNA relapse. During the ctDNA screening phase, patients will be tested at different timepoints to detect the presence of ctDNA in their blood. Patients who are found to be ctDNA-positive and have no evidence of distant metastasis, will be randomised 1:1 between standard endocrine treatment (the same they were receiving when tested ctDNA positive) versus elacestrant, provided they meet all eligibility criteria. After completion of the protocol treatment period, treatment will be left at the discretion of the treating physician.

This is a phase 1b, open-label, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics of Sapu003 in combination with Exemestane in in patients with advanced mTOR-sensitive solid tumors (HR+/HER2-negative breast cancer, renal cell carcinoma \[RCC\], neuroendocrine tumors \[NETs\], tuberous sclerosis complex \[TSC\]-associated tumors, and hepatocellular carcinoma \[HCC\]).
