Uit de fase 2 acelERA BC-studie blijkt dat giredestrant, een zogeheten selectieve oestrogeen receptor antagonist en -degrader goede resultaten geeft bij borstkankerpatiënten met voorbehandelde ER+ en HER2- gevorderde uitgezaaide borstkanker in vergelijking met de door een arts gekozen vorm van alleen hormoontherapie.

Het primaire eindpunt – dat wil zeggen de door de onderzoeker beoordeelde ziekte progressievrije overleving (PFS) – was niet statistisch verschillend tussen de behandelingsgroepen. Echter patiënten met ESR1-gemuteerde tumoren vertoonden  een trend naar verbeterde PFS-resultaten met de giredestrant behandeling. De behandeling met giredestrant werd goed verdragen, zonder nieuwe ernstige bijwerkingen.

Hoewel de fase 2 acelERA BC-studie geen statistische significantie bereikte voor het primaire INV-PFS-eindpunt, was er een consistent behandelingseffect met giredestrant in de meeste belangrijke subgroepen en een trend naar gunstig voordeel bij patiënten met ESR1-gemuteerde tumoren. Giredestrant werd goed verdragen, met een veiligheidsprofiel vergelijkbaar met dat van PCET en consistent met de bekende risico's van hormoontherapie.

Giredestrant for Estrogen Receptor–Positive, HER2-Negative, Previously Treated Advanced Breast Cancer: Results From the Randomized, Phase II acelERA Breast Cancer Study

PublicationJournal of Clinical Oncology

Context

Key objective
Can the oral, selective estrogen receptor antagonist and degrader (SERD) giredestrant improve outcomes compared with physician's choice of endocrine therapy (PCET) in patients with pretreated, estrogen receptor–positive (ER+), HER2-negative, advanced breast cancer?
Knowledge Generated
Giredestrant did not show statistically significant superiority to PCET with regards to investigator-assessed progression-free survival. In patients with ESR1-mutated tumors, there was a trend toward favorable benefit with giredestrant. Giredestrant was well tolerated, with a safety profile comparable to PCET and consistent with known endocrine therapy risks.
Relevance (G. Fleming)
Hopeful results continue to emerge from studies of novel ER-targeting drugs, with a number appearing to show more activity than historically available agents in the presence of a tumor ESR1 mutation. However their significance in the treatment algorithm for women with ER+, HER2-negative breast cancer remains to be determined.*

Abstract

Purpose

To compare giredestrant and physician's choice of endocrine monotherapy (PCET) for estrogen receptor–positive, HER2-negative, advanced breast cancer (BC) in the phase II acelERA BC study (ClinicalTrials.gov identifier: NCT04576455).

Methods

Post-/pre-/perimenopausal women, or men, age 18 years or older with measurable disease/evaluable bone lesions, whose disease progressed after 1-2 lines of systemic therapy (≤1 targeted, ≤1 chemotherapy regimen, prior fulvestrant allowed) were randomly assigned 1:1 to giredestrant (30 mg oral once daily) or fulvestrant/aromatase inhibitor per local guidelines (+luteinizing hormone–releasing hormone agonist in pre-/perimenopausal women, and men) until disease progression/unacceptable toxicity. Stratification was by visceral versus nonvisceral disease, prior cyclin-dependent kinase 4/6 inhibitor, and prior fulvestrant. The primary end point was investigator-assessed progression-free survival (INV-PFS).

Results

At clinical cutoff (February 18, 2022; median follow-up: 7.9 months; N = 303), the INV-PFS hazard ratio (HR) was 0.81 (95% CI, 0.60 to 1.10; P = .1757). In the prespecified secondary end point analysis of INV-PFS by ESR1 mutation (m) status in circulating tumor DNA–evaluable patients (n = 232), the HR in patients with a detectable ESR1m (n = 90) was 0.60 (95% CI, 0.35 to 1.03) versus 0.88 (95% CI, 0.54 to 1.42) in patients with no ESR1m detected (n = 142). Related grade 3-4 adverse events (AEs), serious AEs, and discontinuations due to AEs were balanced across arms.

Conclusion

Although the acelERA BC study did not reach statistical significance for its primary INV-PFS end point, there was a consistent treatment effect with giredestrant across most key subgroups and a trend toward favorable benefit among patients with ESR1-mutated tumors. Giredestrant was well tolerated, with a safety profile comparable to PCET and consistent with known endocrine therapy risks. Overall, these data support the continued investigation of giredestrant in other studies.
