ABSTRACT
Review of medical records from 173 women with osteoporosis who received abaloparatide treatment revealed that 96.0% had at least one visit for osteoporosis management and 55.5% had medication support group access. The most common reasons for discontinuing treatment were financial (31.2%) and tolerability (22.8%). Most patients (64.8%) completed treatment as prescribed. PURPOSE: Abaloparatide is approved for the treatment of women with postmenopausal osteoporosis at high risk for fracture. This study evaluated real-world treatment patterns for patients new to abaloparatide, regardless of osteoporosis treatment history. METHODS: Data for patients with ≥ 1 prescription for abaloparatide were collected retrospectively from six academic and clinical practice settings across the US. RESULTS: A total of 173 patients were enrolled (mean [SD] age, 69.8 [7.4] years). At the time of abaloparatide treatment initiation, 78.6% had received other osteoporosis medications. Mean (SD) time from discontinuation of osteoporosis medications prior to initiation of abaloparatide was 1.7 (3.2) years. Twenty-four months of follow-up data from the initiation date of abaloparatide was collected from 94.0% of patients and 6.0% of patients had 12-24 months of follow-up. During the follow-up period, 96.0% of patients had at least one visit for osteoporosis management and 55.5% had access to a medication support program. The median duration of therapy was 18.6 months and 105/162 (64.8%) completed abaloparatide treatment as prescribed. The most common reasons for treatment discontinuation were financial (31.2%) and tolerability (22.8%). Following completion of a course of treatment with abaloparatide, 82/162 (50.6%) patients transitioned to another osteoporosis medication. The median time between abaloparatide treatment course completion and the initiation of follow-on medication was 21 days. CONCLUSION: Most patients completed treatment with abaloparatide as prescribed, and over half continued with an antiresorptive agent. This favorable conduct may be the result of regular follow-up visits and accessibility to both medication and patient support services.
ABSTRACT
Despite the availability of various osteoporosis treatments, adherence remains suboptimal. One contributing factor may be patient experience with therapy. This US, multicenter, combined retrospective chart review and patient questionnaire study included postmenopausal women at high risk for fracture and is the first study to describe real-world patient experience with abaloparatide (ABL) injection. Eight geographically diverse secondary care sites in the United States participated (n = 193). Mean ± SD age was 67.4 ±8.62 years. Most patients (86%) were satisfied with the ABL regimen, especially with ease of preparation (82%), ease of storage (87%), and storage convenience (89%), an attribute 83% of the patients thought was important. The majority of patients reported complete satisfaction with the ABL regimen allowing for their ability to conduct daily activities (85%) and convenience to fit into their daily schedule (84%). All reported taking ABL as directed, by injection in the lower abdomen, and 83% of patients reported medium or high adherence. Patients were satisfied with the needle size (76% completely satisfied), and 93% reported never deliberately missing a dose. Although injecting medication (18%) and higher out-of-pocket costs (17%) were deemed the most bothersome attributes, the majority (69%) noted their healthcare team understands how osteoporosis impacts their lives. In multivariable analyses, ease of preparation (OR = 2.62; 95% CI, 1.01-6.81; p = 0.048) and fracture history (OR = 1.72; 95% CI, 1.03-2.86; p = 0.037) were significantly associated with overall satisfaction. Ease of preparation was a predictor of higher satisfaction with treatment convenience (coefficient = 13.60; 95% CI, 8.08-19.12; p = 0.00). Remembering to take the medication was a significant predictor of self-reported adherence (OR = 16.66; 95% CI, 3.30-84.24; p = 0.001). In conclusion, the majority of patients were satisfied with ABL and found it convenient/easy to prepare and store. High self-reported adherence may be associated with positive patient experience including ease of use and adequate support from healthcare providers. © 2020 The Authors.
