Breast cancer outcomes improved with CDK4/6 inhibitor treatment
Full article: https://pubmed.ncbi.nlm.nih.gov/35552673/
A study showed that people with metastatic breast cancer who took an oral drug known as a CDK4/6 inhibitor combined with hormone therapy did better than people who took hormone therapy alone. The drug combination improved the length of time before cancer worsened or returned. After six years of treatment, people who took this drug combination lived longer compared to those who took hormone therapy alone. (Posted 4/5/23)

The following studies look at treatment for people with metastatic ER-positive breast cancer.
- Studies for People With ER-Positive, HER2-Negative Advanced or Metastatic Breast Cancer (VERITAC Studies): The VERITAC studies are looking at the safety of an oral study medicine, ARV-471 (also known as vepdegestrant or PF-07850327), and how well it works either alone or combined with another breast cancer medicine, palbociclib (also known as IBRANCE®).
- Treatment Studies for People with ER-Positive, HER2-Negative Advanced or Metastatic Breast Cancer (TACTIVE-U): The TACTIVE-U studies are looking at the safety of an oral study medicine, ARV-471 (also known as vepdegestrant), and how well it works when combined with other breast cancer medicines.

This study is looking at the efficacy and safety of the selective estrogen receptor degrader (SERD) gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy.
- NCT04975308: A Study of Imlunestrant, Investigator's Choice of Endocrine Therapy, and Imlunestrant Plus Abemaciclib in Participants With ER+, HER2- Advanced Breast Cancer (EMBER-3). This study will evaluate the efficacy and safety of the selective estrogen receptor degrader (SERD) imlunestrant, how it works compared to standard hormone therapy, and how well imlunestrant with abemaciclib works compared to imlunestrant in participants with breast cancer that is ER-positive and HER2-negative.
- NCT05306340: A Study Evaluating the Efficacy and Safety of Giredestrant Plus Everolimus Compared With Exemestane Plus Everolimus in Participants With Estrogen Receptor-Positive, HER2-Negative, Locally Advanced or Metastatic Breast Cancer (evERA Breast Cancer). This study will evaluate the efficacy and safety of the selective estrogen receptor degrader (SERD) giredestrant, plus everolimus compared with exemestane plus everolimus in people with estrogen receptor ER-positive, HER2-negative locally advanced or metastatic breast cancer who have had previous treatment with a CDK4/6 inhibitor and hormone therapy.
- NCT03344965: Olaparib Expanded - Treating Metastatic Breast Cancer in People without gBRCA Mutations. This study will look at whether olaparib is also effective for treating metastatic breast cancer in people who do not have an inherited BRCA mutation. The study is enrolling people with an inherited mutation in PALB2 or an acquired (tumor) mutation in BRCA1 or BRCA2.
- NCT03685331: Olaparib, Palbociclib and Fulvestrant for BRCA-Associated, ER/PR+/HER2-Negative Metastatic Breast Cancer. This study is looking at the side effects and best dose of palbociclib when given with olaparib and fulvestrant for people with HR+/HER2-negative mBC who have a BRCA1 or BRCA2 mutation.
- NCT04072952: ARV-471 Alone and in Combination With Palbociclib in Patients With ER+/HER2- Locally Advanced or Metastatic Breast Cancer. This is a dose escalation and expansion study to learn the safety and tolerability of ARV-471 alone and combined with palbociclib in people with ER+/HER2- locally advanced or metastatic breast cancer who have received prior hormonal therapy and chemotherapy in the locally advanced/metastatic setting.
- NCT04448886: Sacituzumab Govitecan +/- Pembrolizumab In HR+ / HER2 - MBC. This research study is evaluating the safety and effectiveness of Sacituzumab Govitecan with or without Pembrolizumab in metastatic HR+/HER2- breast cancer.
