Conditions

HR+/HER2- advanced breast cancer

Brief summary

Superiority* of TTNT1 in patients receiving capivasertib compared to an evidence-based “standard TTNT1 curve” for patients without capivasertib., Superiority* of PRO-adherence compared to non-adherence regarding TTDQoL (aka DQoL-free interval).

Detailed description

PFS: defined by either: evidence of disease progression as assessed by treating physician or death, OS, Superiority of eHealth support (and summary statistics) regarding TTDQoL compared to patients entering the trial without eHealth support., Multivariable analysis including factors that could contribute to ePRO-adherence., Among patients with eHealth support: Multivariable mediation analysis (PRO-non-adherence as a mediating factor for DQoL) controlling for clinical factors., Among patients without eHealth support: multivariable analysis of impact of clinical factors on DQoL., Evaluation of prophylactic and reactive treatments for AESI management, TTTD, ePROs, AE with CTCAE v5 grade 3+4, AESI-rates, ADR-, SADR-, and SAE-rates, Physician-reported AESI and kind of prophylactic and reactive treatments for AESI management, Physician-reported AESI, prophylactic and reactive treatments for AESI management and TTNT1, Patient-reported tolerability with physician-reported AESI and AESI management, Selected PROs (symptom clusters), Selected clinical endpoints, Self-documented symptoms, Socio-demographic data, Time to Next Treatment 2 (TTNT2), Time to Discontinuation 2 (TTTD2), Progression Free Survival 2 (PFS2)
