Study Summary

This trial will study the effects of a new cancer drug on the tumor and the patient's immune system.

Who is the study for?
This trial is for women over 18 with advanced ER+/HER2- breast cancer who can swallow pills, have good organ function, and can undergo biopsies. They should not be using hormonal birth control or have active cancers (except certain skin cancers), autoimmune diseases, serious infections, or conditions that make biopsy unsafe.Check my eligibility
What is being tested?
The study tests how standard endocrine therapy plus abemaciclib affects immune cells in the tumor environment of breast cancer patients. It involves detailed analysis through single cell RNA sequencing and monitoring changes related to serum estrogen levels.See study design
What are the potential side effects?
Potential side effects include reactions from biopsies, fatigue from treatment, possible digestive issues due to oral medications, and risks associated with changes in immune cell functions which could affect overall immunity.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Changes in serum estrogen (E1 and E2) levels compared to changes in tumor immune cell repertoire and function in response to endocrine therapy and CDK 4/6 inhibition
Changes in serum estrogen (E1 and E2) levels compared to peripheral blood mononuclear cell repertoire and function in response to endocrine therapy and CDK 4/6 inhibition
Secondary outcome measures
Best overall response rate of abemaciclib and endocrine therapy in both treatment arms
Changes in tumor immune cell populations in response to fulvestrant and aromatase inhibitor therapy plus abemaciclib, measured by sequential biopsies
Biopsy

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the primary purpose of taking Cohort 1?

"The first cohort is typically used to treat patients with the pik3ca gene mutation. Additionally, this course of treatment can be taken by those struggling with advanced forms of hr+ her2- breast cancer and malignant neoplasms."

Answered by AI

What is the risk profile for people in Cohort 1?

"Cohort 1's safety level was estimated to be a 2 by our team at Power. This is due to it being a Phase 2 trial, so while there is some data supporting safety, there is none for efficacy."

Answered by AI

How many people are being enrolled in this clinical trial?

"That is accurate. According to the information available on clinicaltrials.gov, this study was posted on September 14th 2020 and updated June 7th 2022. They are looking for 30 participants at a single site."

Answered by AI

Are people with the qualifying condition able to participate in this experiment currently?

"The study, which was originally posted on September 14th 2020, is currently looking for eligible participants. The listing was last edited on June 7th, 2022."

Answered by AI

Are there other research projects that have studied Cohort 1?

"Across the globe, there are 216 active studies being conducted on Cohort 1 with 42 of those in Phase 3. Many of the trials related to Cohort 1 take place in Alicante and Pamplona/Iruña, but 9844 locations total are running similar investigations."

Answered by AI

What is the primary purpose of this clinical trial?

"The primary outcome of this study is to compare changes in serum estrogen levels with changes in tumor immune cell repertoire and function in response to endocrine therapy and CDK 4/6 inhibition. The secondary outcomes include the number of participants with at least one serious adverse event, changes in tumor immune cell populations in response to fulvestrant and aromatase inhibitor therapy plus abemaciclib, and the best overall response rate of abemaciclib and endocrine therapy in both treatment arms."
