NATALEE Trial Summary

This trial is testing a new drug to see if it is effective and safe to use in patients with a certain type of breast cancer.

Who is the study for?
This trial is for adults with early-stage, hormone receptor-positive (HR+), HER2-negative breast cancer who've had surgery to remove the tumor and possibly chemotherapy or radiotherapy if needed. They should be in good physical condition (ECOG 0 or 1) and not have any severe medical conditions that could interfere with the trial. People can't join if they're pregnant, breastfeeding, have HIV/Hepatitis B/C, are on certain drugs affecting liver enzymes, or have had another cancer within the last two years.Check my eligibility
What is being tested?
The study is testing how well Ribociclib works alongside standard endocrine therapy as an additional treatment after surgery for breast cancer. It's a phase III trial where patients are randomly assigned to receive either this combination treatment or just endocrine therapy alone to compare effectiveness and safety.See study design
What are the potential side effects?
Ribociclib may cause side effects like low white blood cell counts which can lead to infection risk, tiredness, nausea, diarrhea, hair thinning and loss of appetite. Endocrine therapy might also cause hot flashes, joint pain and mood swings.
