A randomized, double-blind phase 3 study of AZD9833 plus Palbociclib compared to Anastrozole plus Palbociclib in patients with estrogen receptor-positive HER2-negative breast cancer who have not received systemic treatment for advanced disease (SERENA-4)
Descrizione riassuntiva dello studio
This study is being conducted at approximately 110 hospitals in around 20 countries. In Switzerland, 3 hospitals are involved. The study aims to determine the efficacy and safety of an investigational drug AZ9833 called Camizestrant in patients with estrogen receptor-positive/HER-negative breast cancer. This trial is intended to find out whether the investigational substance Camizestrant (AZD9833) plus Palbociclib is better than Anastrozole plus Palbociclib. Aromatase inhibitors (Anastrozole) are considered the standard therapy for the above-mentioned breast cancer. Unfortunately, the disease often changes during treatment, and thus the therapy becomes less effective over time. Patients develop what is called resistance. Resistant patients are currently treated with a drug called Fulvestrant. It belongs to the same class of drugs as Camizestrant. Fulvestrant is administered once a month as an injection into a muscle. Camizestrant, however, is taken as a tablet daily by mouth. It is hoped that the effect of Camizestrant will be better than that of Fulvestrant because it remains in the body at a higher dose for a longer period. Thus, a breakthrough or at least a delay in resistance to treatment is expected. It is planned that 1680 patients will be pre-screened worldwide to randomize 1342 participants into study treatment in one of two groups (in Switzerland 3-5 patients). Patients will be randomly assigned in a 1:1 ratio to one of two treatment groups. Treatment in both groups will continue until disease progression, unacceptable side effects occur, or if the investigators have other reasons to end study participation. After that, follow-up will begin every 12 weeks until death, study end, or withdrawal of consent.

Intervento studiato
Patients will be randomly assigned in a 1:1 ratio to one of the following two treatment groups:
Group A: Investigational substance Camizestrant (AZD9833) + Palbociclib
Group B: Anastrozole (Aromatase inhibitor) + Palbociclib
Medications in this study are taken orally (by mouth) as a tablet.

Criteri di inclusione/esclusione
INCLUSION CRITERIA
Full list of inclusion criteria
- Pre-/peri-menopausal women or men can be enrolled if amenable to be treated with
concomitant, approved LHRH agonists for the duration of the study treatment.
- De novo Stage 4 disease, or recurrence from early stage disease after at least 24
months of standard adjuvant endocrine therapy. Note that at least 12 months must
have elapsed since the patient's last dose of adjuvant AI therapy without disease
progression on treatment. Note that a 2-week washout period is required after the
last dose of tamoxifen prior to randomisation.
- Histologically or cytologically documented diagnosis of ER+, HER2-negative breast
cancer based on local laboratory results.
- Previously untreated with any systemic anti-cancer therapy for their locoregionally
recurrent or metastatic ER+ disease.
- Measurable disease as defined per RECIST v.1.1 OR at least one lytic or mixed (lytic
+ sclerotic) bone lesion with a soft tissue component that can be assessed by CT or
MRI.
- Eastern Cooperative Oncology Group performance status of 0 or 1.
- Adequate organ and marrow function.
- Willingness and ability to comply with scheduled visits, treatment plan, laboratory
tests, and other study procedures.
INFORMATION FOR TRIAL PARTICIPANTS

- Have breast cancer that has already spread into other parts of the body at the time
of diagnosis, or has come back after at least 2 years of a standard endocrine
treatment

- Have never received any type of cancer therapy that affects the whole body for
