En undersøgelse, der evaluerer effektiviteten og sikkerheden af ​​Giredestrant Plus Everolimus sammenlignet med Exemestane Plus Everolimus hos deltagere med østrogenreceptorpositiv, HER2-negativ, lokalt avanceret eller metastatisk brystkræft (evERA brystkræft)

30. oktober 2026 opdateret af: Genentech, Inc.

Et fase III, randomiseret, åbent, multicenter-studie, der evaluerer effektiviteten og sikkerheden af ​​Giredestrant Plus Everolimus sammenlignet med Exemestane Plus Everolimus hos patienter med østrogenreceptorpositiv, HER2-negativ, lokalt avanceret eller metastatisk brystkræft

This Phase III, randomized, open-label, multicenter study will evaluate the efficacy and safety of giredestrant plus everolimus compared with the physician's choice of endocrine therapy plus everolimus in participants with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer who have had previous treatment with cyclin-dependent kinase 4/6 inhibitors (CDK4/6is) and endocrine therapy, either in the locally advanced/metastatic or the adjuvant setting.

Prior treatment with another oral selective estrogen receptor degrader (SERD), proteolysis targeting chimera (PROTAC), complete estrogen receptor antagonist (CERAN), novel oral selective estrogen receptor modulator (SERM), or everolimus in any setting. Prior fulvestrant is allowed if treatment was terminated at least 28 days prior to randomization. Prior treatment with tamoxifen is allowed.
  2. Progression on more than 2 prior lines of systemic endocrine therapy in the locally advanced unresectable or metastatic breast cancer setting
  3. Prior chemotherapy for locally advanced unresectable or metastatic disease
  4. Treatment with strong Cytochrome P450 3A4 (CYP3A4) inhibitors or inducers within 14 days or 5 drug elimination half-lives (whichever is longer) prior to randomization
  5. Treatment with any investigational therapy within 28 days prior to initiation of study treatment
  6. Major surgery, chemotherapy, radiotherapy, or other anti-cancer therapy within 14 days prior to randomization
  7. History of any other malignancy other than breast cancer within 5 years prior to screening, except for appropriately treated carcinoma in situ of the cervix, nonmelanoma skin carcinoma, papillary thyroid cancer treated with surgery, Stage I endometrial cancer, or other non-breast cancers at very low risk of recurrence
  8. Advanced, symptomatic, visceral spread that is at risk of life-threatening complications in the short term
  9. Known active uncontrolled or symptomatic central nervous system (CNS) metastases, carcinomatous meningitis, or leptomeningeal disease
  10. Active cardiac disease or history of cardiac dysfunction
  11. Known clinically significant history of liver disease consistent with Child-Pugh Class B or C including active viral or other hepatitis virus, current alcohol abuse, or cirrhosis
  12. Active inflammatory bowel disease, chronic diarrhea, short bowel syndrome, or major upper gastrointestinal (GI) surgery including gastric resection
  13. Interstitial lung disease or severe dyspnea at rest or requiring oxygen therapy
  14. Serious infection requiring oral or intravenous (IV) antibiotics, or other clinically significant infection, within 14 days prior to randomization
  15. Any serious medical condition or abnormality in clinical laboratory tests that, in the investigator's judgment, precludes the patient's safe participation in and completion of the study
  16. Known allergy or hypersensitivity to any of the study drugs or any of their excipients
  17. For premenopausal or perimenopausal women and for men: known hypersensitivity to LHRH agonists
  18. Pregnant or breastfeeding

Intervention / Behandling
Eksperimentel: Giredestrant plus Everolimus

Participants will receive treatment with giredestrant 30 milligrams (mg) orally once a day (QD) on Days 1-28 of each 28-day cycle until unacceptable toxicity or disease progression as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1).

Andre navne:
  • GDC-9545
  • RO7197597
  • RG6171

Participants will receive treatment with everolimus 10 mg orally QD during each 28-day cycle until unacceptable toxicity or disease progression as determined by the investigator according to RECIST v1.1.

Only premenopausal/perimenopausal female participants and male participants will receive a luteinizing hormone-releasing hormone (LHRH) agonist on Day 1 of each 28-day treatment cycle. The investigator will determine and supply the appropriate LHRH agonist locally approved for use in breast cancer.

A compounded alcohol-free mouthwash of dexamethasone (0.5 mg in 5 mL) will be supplied, where feasible. It is strongly recommended for prophylaxis or treatment of stomatitis/mucositis. Participants should use the alcohol-free mouthwash of dexamethasone four times QD for 8 weeks started concurrently with study treatment, and use it reactively thereafter with the first appearance of symptoms.

Aktiv komparator: Physician's Choice of Endocrine Therapy plus Everolimus

The physician's choice of endocrine therapy is defined as either exemestane, fulvestrant, or tamoxifen.

Participants will receive treatment with everolimus 10 mg orally QD during each 28-day cycle until unacceptable toxicity or disease progression as determined by the investigator according to RECIST v1.1.

Only premenopausal/perimenopausal female participants and male participants will receive a luteinizing hormone-releasing hormone (LHRH) agonist on Day 1 of each 28-day treatment cycle. The investigator will determine and supply the appropriate LHRH agonist locally approved for use in breast cancer.

A compounded alcohol-free mouthwash of dexamethasone (0.5 mg in 5 mL) will be supplied, where feasible. It is strongly recommended for prophylaxis or treatment of stomatitis/mucositis. Participants should use the alcohol-free mouthwash of dexamethasone four times QD for 8 weeks started concurrently with study treatment, and use it reactively thereafter with the first appearance of symptoms.

If exemestane is chosen as the physician's choice of endocrine therapy, the participant will receive exemestane at a dose of 25 mg orally once a day (QD) on Days 1-28 of each 28-day cycle or as per local label, until unacceptable toxicity or disease progression as determined by investigator according to RECIST v1.1.

If fulvestrant is chosen as the physician's choice of endocrine therapy, the participant will receive fulvestrant in the clinic at a dose of 500 mg intramuscularly on Day 1 and Day 15 of Cycle 1, then Day 1 of each cycle thereafter (1 cycle is 28 days) or as per local prescribing information, until unacceptable toxicity or disease progression as determined by investigator according to RECIST v1.1.

If tamoxifen is chosen as the physician's choice of endocrine therapy, the participant will receive tamoxifen at a dose of 20 mg orally QD on Days 1-28 of each 28-day cycle or as per local prescribing information, until unacceptable toxicity or disease progression as determined by investigator according to RECIST v1.1.

The Intent-to-Treat (ITT) population consists of all randomized participants, and the ESR1m subpopulation is defined as participants in the ITT population whose tumors harbor a detectable Estrogen Receptor 1 (ESR1) mutation at baseline as measured in circulating tumor DNA (ctDNA).

From randomization until the first occurrence of disease progression or death from any cause, whichever occurs first (up to 42 months)

Objective Response Rate (ORR), as Determined by the Investigator According to RECIST v1.1, in the ESR1m Subpopulation and ITT Population
Tidsramme: From randomization until progressive disease or death (up to 42 months)

The objective response rate is defined as the percentage of participants with a complete response (CR) or partial response (PR) on two consecutive occasions at least 4 weeks apart.

Tidsramme: From randomization until 90 days after treatment discontinuation (up to 42 months)

Time to confirmed deterioration in pain severity is defined as the time from randomization to the first documentation of ≥2-point increase from baseline on the "worst pain" item score (scale from 0 = "No pain" to 10 = "Pain as bad as you can imagine") held for 2 consecutive time points, or a ≥2-point increase followed by death attributable to cancer progression within 28 days from the last assessment.
