This study evaluates the safety of abemaciclib in combination therapies (letrozole, anastrozole, tamoxifen, exemestane, exemestane plus everolimus, trastuzumab, LY3023414 plus fulvestrant, pertuzumab plus trastuzumab with loperamide, or ongoing endocrine therapy) for breast cancer that has spread to other parts of the body.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Eli Lilly and Company (LLY) is the sponsoring company for this trial. BiotechSign currently grades this company C (54/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
