Abstract
- In monarchE, abemaciclib demonstrated a sustained benefit in invasive disease-free survival and a tolerable safety profile at 42-months median follow-up. With no expected disease-related symptoms, therapies in the adjuvant setting should preserve quality of life (QoL). With all patients off abemaciclib, we report updated patient-reported outcomes (PROs) for the full 2-year treatment period and follow-up. Patients completed PROs including FACT-B, FACT-ES, and FACIT-Fatigue at baseline, 3, 6, 12, 18, and 24 months during treatment, and 1, 6, and 12 months after treatment discontinuation. Mixed effects repeated measures model estimated changes from baseline within and between arms for QoL scales and individual items. Meaningful changes were prespecified and no statistical testing was performed. Frequencies of responses to items associated with relevant adverse events and treatment bother were summarized. At baseline, completion rates for PRO instruments were >96 %. Mean changes from baseline for all QoL scales were numerically similar within and between arms (ie, less than prespecified thresholds). The same was observed for all individual items, except diarrhea. Within abemaciclib arm, meaningful differences for diarrhea were observed at 3 and 6 months (mean increases of 1.19 and 1.03 points on 5-point scale, respectively). During treatment, most patients in both arms (69–78 %) reported being bothered "a little bit" or "not at all" by side effects. Overall, patterns for fatigue were similar between arms. During post-treatment follow-up, PROs in both arms were similar to baseline. PRO findings confirm a tolerable and reversible toxicity profile for abemaciclib. QoL was preserved with the addition of adjuvant abemaciclib to endocrine therapy, supporting its use in patients with HR+, HER2-, high-risk early breast cancer. • Quality of life was well preserved with the addition of abemaciclib to ET in EBC. • No clinically meaningful differences across arms in bothered by side effects and fatigue. • Differences in diarrhea at 3-6 months did not impact overall quality of life. • No residual symptoms reported after completion of abemaciclib. • Common ET symptoms (hot flush, joint pain) were less frequent in abemaciclib arm.
