Study summary

This is a non-interventional, ambispective, observational cohort study describing the real-world safety data of approximately 550 Hormone receptor / Human epidermal growth factor receptor 2 (HR+/HER2-) advanced/metastatic breast cancer patients who have received ribociclib combined with hormonal therapy in pre-and postmenopausal women or men in Middle Eastern countries.

Read the detailed description

The investigators will have a six-month recruitment period to include the eligible subjects as per the protocol selection criteria. Retrospective patients should have been on Ribociclib in combination with hormonal therapy for at least 18 months and stopped the medication before the patient's recruitment.

Ambispective patients should have initiated Ribociclib, in combination with hormonal therapy, for at least 12 months before the patient's recruitment date and are still on Ribociclib in combination with hormonal therapy at recruitment. These patients will be followed up till progression, death, Ribociclib discontinuation due to adverse events, or till a maximum period of 6 months, whichever comes first.

Data will be collected from patient electronic medical records in the sites chosen for patients who received Ribociclib, in combination with hormonal therapy, in the first or second-line setting available in the relevant institutions.

A total of 550 patients is planned for this study. The planned sample size should capture very common adverse events reported in previous studies as well as adverse events ≥ 10% occurring in grade 3 and grade 4 with precision ±2.5%.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Interventions

  • Otherribociclib

    There is no treatment allocation for NIS trials, patients on administered ribociclib by prescription will be enrolled. Treatment plan represents the prescription.

    Also known as: CLEE011

This study also gives Ribociclib. No intervention listed here names it: that was found by reading the record.

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2024 to primary completion in Jun 2025, 15 months.

Of 189 industry-sponsored observational studies under Breast Neoplasms, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 26 and three quarters within 70. This study's 15 months is below that.

Counting every sponsor, half of 1,380 studies reached it within 55 months; a quarter within 25 and three quarters within 126.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
