IMPlementing geriatric assessment for dose Optimization of CDK 4/6-inhibitors in older bReasT cAncer patieNTs – a pragmatic randomized-controlled trial (IMPORTANT trial)
EU CTIS ID: 2023-506620-87-00
What this study is testing
The primary objective of the IMPORTANT study is to investigate the time to treatment failure (TTF) in vulnerable or frail older breast cancer patients treated with lower initial dose of CDK 4/6-inhibitors plus endocrine therapy compared to the recommended full dose of CDK 4/6-inhibitors.
- Phase III and phase IV (Integrated)

Who can take part
You may be able to join if
- Patients male or female aged at least 65 years old at the time of informed consent. Male patients should use adequate contraceptive methods (e.g., double-barrier contraception) during therapy and for at least 14 weeks after completing therapy.
- Able to understand and consent in English language or in native language for each participating country.
- Histologically or cytologically confirmed diagnosis of HR-positive (defined as estrogen-receptor ≥ 1%), HER2-negative breast cancer according to analysis of the most recent tumor specimen by local laboratory.
- Advanced (locoregionally recurrent or metastatic) breast cancer not amenable to curative treatment.
- No prior systemic treatment for advanced disease (recurrence during neo-/adjuvant endocrine therapy is allowed). A prior period of treatment with aromatase inhibitors or fulvestrant for up to 56 days from the CDK 4/6-inhibitor initiation is allowed as long as there is no disease progression during this time period.
- Adjuvant treatment with CDK4/6-inhibitors is allowed provided a disease-free interval from treatment end >12 months
You likely can't join if
- Patients considered from treating physician as non-suitable for treatment with CDK 4/6-inhibitors.
- Contraindications according to SmPC for the CDK 4/6-inhibitors that is planned to be used.Specifically, any hypersensitivity to the active substance or to any of the excipients or to peanut, soya (for ribociclib) or use of preparations containing St. John’s Wort (for palbociclib) are contraindications.
- Presence of visceral crisis, lymphangitis carcinomatosis, or leptomeningeal carcinomatosis.
- History of any other cancer (except of non-melanoma skin cancer or carcinoma in-situ of the cervix), unless in complete remission with no therapy for a minimum of 3 years.
- Participating in other interventional trial.
- Patients with cognitive impairment (as assessed by treating physician) that preclude the ability to fill out the self-reported CGA.
