ACT-FASTER, a Prospective Cohort Study Exploring Treatment Patterns with Fulvestrant and Exemestane in Postmenopausal Patients with Advanced Hormone Receptor-Positive Breast Cancer under Real-Life Conditions in Germany.

ABSTRACT: Background:Endocrine therapy is recommended for the treatment of postmenopausal women with hormone receptor-positive (HR+) advanced breast cancer (ABC). Methods:ACT-FASTER was a German prospective non-interventional cohort study in postmenopausal women with HR+ ABC receiving fulvestrant 500 mg as first line (1 L), second line (2 L) or third line (3 L), or exemestane (any line) in the real-world palliative setting. Primary study objectives included the effectiveness of fulvestrant according to line of palliative treatment measured by time to progression (TTP), and real-life data on the epidemiology and management of these patients. Results:Of 498 evaluable patients (mean age 67.5 years), 99% were estrogen receptor-positive. On study, 86.7% of patients received fulvestrant 500 mg and 13.3% exemestane. Median TTP was 9.7 months in patients receiving fulvestrant 1 L; 6.8 months for 2 L; and 6.7 months for 3 L. The comparison between fulvestrant 1 L palliative treatment and 2 L or 3 L showed that early initiation of treatment prolonged TTP (hazard ratio 1.26; 95% confidence interval 1.08-1.48). Treatments were well tolerated. Conclusion:Fulvestrant 500 mg was administered successfully to patients under daily practice conditions, and both medications were well tolerated. TTP was longest in patients treated with fulvestrant 500 mg 1 L compared with 2 L and 3 L in the palliative care setting.

Project description:BackgroundGenome-wide association studies have identified several genomic regions that are associated with stroke risk, but these provide an explanation for only a small fraction of familial stroke aggregation. Genotype by environment interactions may contribute further to such an explanation. The Women's Health Initiative (WHI) clinical trial found increased stroke risk with postmenopausal hormone therapy (HT) and provides an efficient setting for evaluating genotype-HT interaction on stroke risk.MethodsWe examined HT by genotype interactions for 392 SNPs selected from candidate gene studies, and 2,371 SNPs associated with changes in blood protein concentrations after hormone therapy, in analyses that included 2,045 postmenopausal women who developed stroke during WHI clinical trial and observational study follow-up and one-to-one matched controls. A two-stage procedure was implemented where SNPs passing the first stage screening based on marginal association with stroke risk were tested in the second stage for interaction with HT using case-only analysis.ResultsThe two-stage procedure identified two SNPs, rs2154299 and rs12194855, in the coagulation factor XIII subunit A (F13A1) region and two SNPs, rs630431 and rs560892, in the proprotein convertase subtilisin kexin 9 (PCSK9) region, with an estimated false discovery rate <0.05 based on interaction tests. Further analyses showed significant stroke risk interaction between these F13A1 SNPs and estrogen plus progestin (E+P) treatment for ischemic stroke and for ischemic and hemorrhagic stroke combined, and suggested interactions between PCSK9 SNPs with either E+P or estrogen-alone treatment.ConclusionsGenotype by environment interaction information may help to define genomic regions relevant to stroke risk. Two-stage analysis among postmenopausal women generates novel hypotheses concerning the F13A1 and PCSK9 genomic regions and the effects of hormonal exposures on postmenopausal stroke risk for subsequent independent validation.
