Brief Summary

A Multicenter Open-label Non-comparative 2-Stage Phase 1a/1b Study to Assess the Safety and Pharmacokinetics of Oral BCD-115 (JSC BIOCAD, Russia) in Combination with Endocrine Therapy in Women with ER(+) HER2(-) Local Advanced and Metastatic Breast Cancer

Detailed Description

Multicentre dose-finding open-label non-comparative phase Ia/Ib clinical trial for investigation of the safety, tolerability, pharmacokinetics of BCD-115 administered p.o. with intrapatient dose escalation in the population of patients with ER(+) HER2(-) advanced breast cancer in combination with a standard dose of endocrine therapy.

The trial will be conducted in two stages:

Stage 1 - finding of the maximum tolerated dose, determination of the recommended dose for Stage 2.

Stage 2 - study of the recommended dose from Stage 1 of BCD-115, analysis of tolerability and safety of selected dose/doses in additional cohorts, and determination of the estimated therapeutic dose/doses for further clinical studies.

Conditions
