HIDE SMILES / InChI
ARN-810 (GDC-0810) is a novel, orally bioavailable, estrogen receptor antagonist that induces proteasomal estrogen receptor degradation in breast cancer cell lines at picomolar concentrations and tumor regression in tamoxifen-sensitive and resistant BC xenograft models. Results from a first-in-human phase I/IIa study of ARN-810 indicate that it is tolerable and may benefit some postmenopausal women with advanced estrogen receptor-positive breast cancer. Development of ARN-810 was discontinued.

Sample Use Guides

ARN-810 was tested using standard 3+3 dose escalation to assess safety, PK, and Recommended Phase 2 Dose (RP2D). Key eligibility criteria included ER+ (HER2-) metastatic BC progressing ≥ 6 months (m) on endocrine therapy and ≤ 2 prior chemotherapies. From April 2013 to June 2014, 32 patients (pts) (median age 61 (range 43 – 75); median number of prior therapies = 3 (range 1 – 7); visceral metastases 54%) were enrolled at 5 doses (100, 200, 400, 600, 800 mg) and 2 different regimens (once [QD] and twice daily) given orally with and without fasting. The drug is undergoing further evaluation in a phase II study, at a recommended dose of 600 mg.

PRIMARY MedKoo CAT NO.: 206041, CAS N).: 1365888-06-7Description: GDC-0810, also known as ARN-810 and RG6046, an orally bioavailable Selective Estrogen Receptor Degrader (SERD) that demonstrates robust activity in tamoxifen-resistant breast cancer xenografts. GDC-0810 functions by binding to the estrogen receptor, inducing a conformational change resulting in the degradation of the receptor. GDC-0810 or ARN-810 demonstrates robust activity in models of tamoxifen-sensitive and tamoxifen-resistant breast cancer, and is currently in clinical trials in women with locally advanced or metastatic estrogen receptor-positive breast cancer.
