monarcHER Trial Summary

This trial will compare abemaciclib+trastuzumab with or without fulvestrant to trastuzumab+ standard of care chemotherapy in women with HR+, HER2+ breast cancer.

Who is the study for?

This trial is for women with HR+, HER2+ advanced or metastatic breast cancer who've had at least two prior HER2-targeted treatments. They must have good organ function, not be pregnant, and agree to contraception. Exclusions include recent heart issues, untreated brain metastases, major surgery within 14 days, certain infections or allergies to study drugs.Check my eligibility

What is being tested?

The study tests the effectiveness of abemaciclib combined with trastuzumab and possibly fulvestrant against standard chemotherapy plus trastuzumab in patients previously treated for advanced breast cancer. It aims to see if this new combination can better control the disease.See study design

What are the potential side effects?

Potential side effects may include diarrhea, fatigue, low white blood cell counts (increasing infection risk), nausea, liver enzyme changes suggesting liver injury, deep vein thrombosis or pulmonary embolism (blood clots), and potential harm to a fetus.

However, there is an abundance of other research opportunities; 2287 studies search for those with hormone receptor (hr)-positive breast cancer and 379 clinical trials seek out participants to test Abemaciclib."

Answered by AI

Is Abemaciclib generally safe for consumption by people?

"According to our team at Power, Abemaciclib is relatively safe and thus deserving of a 2 rating as there is existing evidence that it meets safety standards but no efficacy data has yet been collected."

Answered by AI

What are the conventional applications of Abemaciclib?

"Abemaciclib has established efficacy for preventing endocrine therapy, and can additionally be beneficial in managing disease, metastatic adenocarcinoma of the gastroesophageal junction, and post-surgical protocols."

Answered by AI

What prior investigations have been conducted involving Abemaciclib?

"Abemaciclib was first investigated at Ospedale di Circolo e Fondazione Macchi in 1999. Presently, there are 470 completed studies of this medication and an additional 379 enrolling patients across the globe; a considerable portion is based in East Setauket, New york."

Answered by AI

Is this research currently enrolling participants?

"This clinical trial is no longer accepting participants; it was last updated on August 8th, 2022. For those looking for alternative studies related to hormone receptor (hr)-positive breast cancer, there are 2287 trials now recruiting and 379 research initiatives that require Abemaciclib patients."

Answered by AI

What is the geographical scope of this trial’s implementation?

"Currently, 34 different clinical trial centres are participating in the recruitment process. Examples of these locations include North Shore Hematology Oncology Associates in East Setauket, Tennessee Oncology PLLC in Nashville and Northwest Medical Specialties, PLLC in Puyallup amongst other sites."
