Evaluering af alternativ injektionssted for Goserelinacetat til undertrykkelse af ovariefunktion (OFS) hos lokale og lokalt fremskredne premenopausale patienter med hormonreceptorpositiv brystkræft

29. september 2026 opdateret af: Mayo Clinic

MC250301, OptiOFS: Et randomiseret fase II-studie af alternativt injektionssted for goserelinacetat til undertrykkelse af ovariefunktion (OFS) ved lokal og lokalt fremskreden præmenopausal brystkræft

This phase II trial determines if giving goserelin acetate injections in the upper gluteal region is as effective for ovarian function suppression (OFS) as giving injections in the abdomen for ovarian function suppression (OFS) in premenopausal patients with hormone receptor positive breast cancer that has not spread to other parts of the body (localized) or that has spread to nearby tissue or lymph nodes (locally advanced). Goserelin acetate is a drug used to treat prostate cancer, relieve the symptoms of advanced breast cancer, and treat problems with the endometrium (lining of the uterus). Goserelin acetate initially causes the pituitary gland to make more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), temporarily increasing testosterone levels in men and estrogen levels in women. With continued use, goserelin acetate lowers the amount of LH and FSH the pituitary gland releases, leading to a drop in testosterone levels in men and estrogen levels in women. Goserelin acetate may stop the growth of cancer cells that need testosterone or estrogen to grow. It is a type of hormone therapy called a luteinizing hormone-releasing hormone (LHRH) agonist. Giving goserelin acetate injections in the upper gluteal region may be as effective for OFS as giving injections in the abdomen for OFS in premenopausal patients with localized or locally advanced hormone receptor positive breast cancer.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Arm I (Goserelin acetate)

Patients receive goserelin acetate SC in the abdomen on day 1 of each cycle. Cycles repeat every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients receive goserelin acetate SC in the upper gluteal region on day 1 of each cycle. Cycles repeat every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo blood sample collection on study.

Foranstaltningsbeskrivelse
Tidsramme
Ovarian function suppression (OFS) maintenance
Tidsramme: 6 months

Failure to maintain OFS (yes; no) is defined as estradiol ≥ 10 pg/mL on two separate occasions. Will be based on calculating the within-arm sample proportion of patients for whom upper gluteal region administration of goserelin for 6 months failed to maintain OFS after switching from monthly abdominal administration of goserelin and corresponding upper bound of the one-sided 97.5% confidence interval (CI). Provided that the upper bound of the one sided 97.5% CI excludes 10%, the primary aim for that arm will have been met.

Change in Patient Reported Outcomes and Quality of Life
Tidsramme: Baseline, 3 months, 6 months, 9 months, 12 months

Assessed by a study-specific questionnaire related to injection pain and post-injection symptoms such as bruising, swelling, or skin irritation. The questionnaire consists of 7 questions, one yes/no question; 5 questions answered on an 11-point scale from 0 (none) to 10 (most you can imagine); and one overall quality of life question answered on a scale of 0 (as bas as it can be) to 10 (as good as it can be). Higher scores for symptom questions indicate more sever symptoms. Any change from baseline will be summarized descriptively.
