IMPORTANT · IMPlementing geriatric assessment for dose Optimization of CDK 4/6-inhibitors in older bReasT cAncer patieNTs

Current evidence from both randomized trials and real-world evidence studies suggests that older breast cancer patients derive clinical benefit from the addition of CDK 4/6-inhibitors to endocrine therapy but with higher risk for adverse events and treatment discontinuation compared to younger patients. The IMPORTANT project will design and conduct a pragmatic clinical study with a decentralised approach for older patients with advanced breast cancer aiming at high level of evidence (level I) with multi-layer results that can enable changes in current clinical practice. This study will be conducted across 6 (six) EU countries, and will include more than 500 female and male patients. The project will also perform a series of analyses over a) a wide range of clinical-relevant primary and secondary endpoints targeting to contribute to current clinical practice and b) the implementation of specific strategies aiming at more individualized treatment and follow-up approaches to a clinical trial setting that highly resembles real-world setting due to the trial's pragmatic design.The project will be developed in 60 months by a competitive consortium of 19 partners from 11 countries, which corresponds to a well-balanced structure, involving clinical sites, SMEs, universities and patient advocacy organizations. Despite the great diversity of entities within the proposal, IMPORTANT partners bring state-of-the-art complementary skills ensuring the ability of the consortium to successfully complete the proposed work.This action is part of the Cancer Mission cluster of projects on ‘Diagnosis and treatment’.
