Brief Summary:
The study is intended to show superiority of AZD9833 in combination with palbociclib (a CDK4/6 inhibitor) versus anastrozole (an aromatase inhibitor) and palbociclib as the initial treatment of patients with hormone receptor-positive (ER-positive), human epidermal growth factor 2-negative (HER2-negative) advanced/metastatic breast cancer.
INFORMATION FOR TRIAL PARTICIPANTS
In this trial, the researchers will look at how well camizestrant with palbociclib works, compared with anastrozole with palbociclib, in participants with breast cancer that has either spread into other parts of the body at the time of diagnosis, or has come back after at least 2 years of standard endocrine treatment.
Participants in this trial will have breast cancer that has ER proteins but does not have overexpression of HER2 protein.

Primary Outcome Measures :
- Progression-free survival (PFS) assessed by the Investigator as defined by response evaluation criteria in solid tumors (RECIST) version 1.1 [ Time Frame: From randomization until progression per RECIST 1.1 as assessed by the investigator at local site or death due to any cause (up to 5 years) ]PFS is defined as the time from randomization to objective disease progression (as assessed by RECIST) or death.
Secondary Outcome Measures :
- Overall survival (OS) [ Time Frame: From randomization until the date of death due to any cause (up to 8 years) ]The OS is defined as the time from randomization to death due to any cause.
- Second progression-free survival (PFS2) [ Time Frame: From randomization to the earliest of the progression event (following the initial progression), subsequent to first subsequent therapy or death (up to 5 years) ]Time to second progression or death (PFS2) will be defined as the time from randomisation to the earliest of the progression event (following the initial progression), subsequent to first subsequent therapy or death.
- Objective response rate (ORR) assessed by the Investigator as defined by RECIST version 1.1 [ Time Frame: From randomization until a response or in the absence of a response from randomization up until progression, or the last evaluable assessment in the absence of progression (up to 5 years) ]ORR is defined as the proportion of patients who have a CR or partial response, as determined by the investigator at local site per RECIST 1.1.
- Duration of response (DoR) assessed by the Investigator as defined by RECIST version 1.1 [ Time Frame: From the date of first documented response until date of documented progression per RECIST 1.1 as assessed by the investigator at local site or death due to any cause (up to 5 years) ]The DoR will be defined as the time from the date of first documented response until date of documented progression or death in the absence of disease progression.
- Time to chemotherapy (TTC) [ Time Frame: From randomization until the earlier of the start date of chemotherapy or death due to any cause (up to 5 years) ]Time to chemotherapy is defined as the time from randomization until the earlier of the start date of chemotherapy or death due to any cause.
- Time to first subsequent anti-cancer therapy (TFST) [ Time Frame: From randomization until the earlier of start date of the first subsequent anti-cancer therapy after discontinuation of randomized treatment, or death due to any cause (up to 5 years) ]TFST is defined as time from randomization until the earlier of start date of the first subsequent anti-cancer therapy after discontinuation of randomized treatment, or death due to any cause.
- Clinical benefit rate at 24 weeks (CBR24) [ Time Frame: At least 23 weeks after randomisation ]CBR at 24 weeks is defined as the percentage of participants who have a complete response (CR) or partial response or who have stable disease (SD) per RECIST 1.1 as assessed by the investigator at local site for at least 23 weeks after randomization (to allow for an early assessment within the assessment window).
- Time to second subsequent therapy (TSST) [ Time Frame: From randomization until the earlier of start date of the second subsequent anti-cancer therapy after discontinuation of first subsequent treatment, or death due to any cause (up to 5 years) ]TSST is defined as time from randomization until the earlier of start date of the second subsequent anti-cancer therapy after discontinuation of first subsequent treatment, or death due to any cause.
- Plasma concentration of AZD9833 at specified timepoints [ Time Frame: on Day 15 ]To assess the steady state PK of AZD9833 in combination with palbociclib in all participants who receive at least one dose of AZD9833 per the protocol, for whom there are at least one reportable PK concentration.
- Change from baseline in EORTC QLQ-C30 scale scores [ Time Frame: From baseline to 24 weeks post progression (up to approximately 5 years) ]Change from baseline in EORTC QLQ-C30 scale scores for each patient at each post-baseline visit. The comparison will include all randomised patients, as randomised, with baseline and at least one post-baseline visit score for the scale score.
- Change from baseline in EORTC QLQ-BR45 scale scores [ Time Frame: From baseline to 24 weeks post progression (up to approximately 5 years) ]Change from baseline in EORTC QLQ-BR45 scale scores for each patient at each post-baseline visit. The comparison will include all randomised patients, as randomised, with baseline and at least one post-baseline visit score for the scale score.

- Active infection including tuberculosis, HBV and HCV.
INFORMATION FOR TRIAL PARTICIPANTS
Participants cannot join the trial if they:
- Have uncontrolled cancer that has spread to the brain or the spinal cord
- Have received certain treatments for cancer in the past but the cancer came back within 1 year
- Had certain types of tumors in the past, which the study doctors think could come back
