Can a slower dose of this cancer drug ease harsh side effects?

NCT ID NCT06001762

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether gradually increasing the dose of abemaciclib (a targeted cancer drug) can reduce side effects like diarrhea and help patients stick with treatment. It involves 90 people with early-stage, hormone receptor-positive, HER2-negative breast cancer who are also taking standard hormone therapy. The goal is to see if this slower approach is better tolerated than the usual fixed dose.

What this could mean

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

Active substance

abemaciclib (a targeted cancer drug)

What this could lead to

If successful, this could lead to a better-tolerated way to take abemaciclib, reducing side effects like diarrhea and helping more patients complete their treatment.

What could go wrong

This is a small, early-phase trial (90 people) testing tolerability, not effectiveness. The dose-escalation strategy may still cause side effects or not improve outcomes.
