Summary

This study tests whether a smartphone app that sends text reminders can help breast cancer patients take their medication (palbociclib) on time. 45 participants will either use a paper diary or receive text reminders over three treatment cycles. The goal is to see if the app is easy to use and improves medication accuracy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
palbociclib (Ibrance)
What this could lead to
If successful, this could show that simple text reminders help patients stick to their medication schedule, potentially improving treatment effectiveness.
What could go wrong
This is a small, early feasibility study with only 45 people. It does not test whether the reminders actually improve health outcomes, and results may not apply to all patients.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

45 people

The number who actually took part.

Started

Dec 2019

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Female participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
