What's being studied?
<ul class="seamTextUnorderedList">
<li class="seamTextUnorderedListItem">Camizestrant (AZD9833) is an experimental type of anti-estrogen therapy called a selective estrogen receptor degrader (SERD). SERDs bind to and break down estrogen receptors.</li>
<li class="seamTextUnorderedListItem">Palbociclib (Ibrance®) and abemaciclib (Verzenio®) are CDK4/6 inhibitors, a type of targeted therapy.</li>
<li class="seamTextUnorderedListItem">CDK4/6 inhibitors block two enzymes, CDK4 and CDK6, that help cancer grow.</li>
<li class="seamTextUnorderedListItem">Letrozole (Femara®) and anastrozole (Arimidex®) are aromatase inhibitors, a type of hormone therapy.</li>
<li class="seamTextUnorderedListItem">Aromatase inhibitors block some production of estrogen that helps cancer grow.</li>
<li class="seamTextUnorderedListItem">Premenopausal and perimenopausal women and men will also be given a drug that will put women in temporary menopause.</li>
<li class="seamTextUnorderedListItem">Targets or mutations: ESR1</li></ul>
