Trial Outcomes & Findings for A Study of Neoadjuvant Letrozole + Taselisib Versus Letrozole + Placebo in Post-Menopausal Women With Breast Cancer (LORELEI) (NCT NCT02273973)

NCT ID: NCT02273973

Last Updated: 2018-05-21

Results Overview

Objective response rate (ORR) was defined as proportion of participants achieving complete response (CR) or partial response (PR). As per modified RECIST v1.1, CR: disappearance of all target lesions, PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.

Timeframe: From Baseline to 16 weeks

Population: ITT population includes all randomized participants regardless of whether they received any study drug (taselisib or placebo).

Objective response rate (ORR) was defined as proportion of participants achieving complete response (CR) or partial response (PR). As per modified RECIST v1.1, CR: disappearance of all target lesions, PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.

To obtain the PEPI score, risk points for relapse-free survival (RFS) and breast cancer-specific survival (BCSS) are assigned depending on the hazard ratio (HR) from the multivariable analysis. The total PEPI score assigned to each participant is the sum of the risk points derived from the primary tumor (pT) stage, regional lymph nodes (pN) stage, Ki67 level, and estrogen receptor status of the surgical specimen. A HR in the range of 1 to 2 receives one risk point; a HR in the 2 to 2.5 range, two risk points; a HR greater than 2.5, three risk points. The total risk point score for each participant is the sum of all the risk points accumulated from the four factors in the model, ranges from 0 (best possible outcome) to 12 (worst possible outcome).

EORTC QLQ-C30 is a cancer-specific instrument with 30 questions used to assess the overall quality of life (QOL) in cancer participants. The first 28 questions used a 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much) for evaluating 5 functional scales (physical, role, social, cognitive, emotional), 8 symptom scales/items (diarrhea, fatigue, dyspnea, appetite loss, insomnia, nausea and vomiting \[N/V\], constipation, and pain) and a single item (financial difficulties). The last 2 questions represented the participant's assessment of overall health and quality of life, used 7-point scale (1=very poor to 7=excellent). EORTC QLQ-C30 global scores were linearly transformed on a scale of 0 to 100, with a high score indicating better QOL. Negative change from Baseline values indicated deterioration in QOL or functioning and positive values indicated improvement. Here, Post surgery= PS.

SECONDARY outcome

Timeframe: Weeks 1, 5, 9, 13, 16, 4-week Post-Surgery

Population: ITT population includes all randomized participants regardless of whether they received any study drug (taselisib or placebo).

EORTC-QLQ-BR23 is a 23-item breast cancer-specific companion module to the EORTC-QLQ-C30 and consists of four functional scales (body image, sexual enjoyment, sexual functioning, future perspective \[FP\]) and four symptom scales (systemic side effects \[SE\], upset by hair loss, arm symptoms, breast symptoms). Questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores were averaged and transformed to 0-100 scale. High score for functional scale indicated high/better level of functioning/healthy functioning. Negative change from Baseline indicated deterioration in QOL and positive change from Baseline indicated an improvement in QOL. Here, Post surgery= PS.
