A phase 3 open-label, randomized multicenter study to evaluate efficacy and safety of secukinumab in pediatric patients with moderate to severe plaque psoriasis: 24-week results.

BACKGROUND: Psoriasis affects 0.13%-2.1% of children and adolescents. Despite a high unmet need, the current treatment options approved for pediatric psoriasis are limited. OBJECTIVE: To evaluate the efficacy and safety of 2 secukinumab dosage regimens (low dose: 75/75/150 mg; high dose: 75/150/300 mg) stratified and randomized by weight (<25 kg, 25 to <50 kg, ≥50 kg) and disease severity (moderate, severe) in pediatric patients aged 6-<18 years with moderate to severe plaque psoriasis. METHODS: This is a phase 3, open-label, randomized, multicenter study (NCT03668613). RESULTS: Both secukinumab doses were superior to historical placebo with respect to psoriasis area and severity index (PASI)-75/90 and investigator global assessment 0/1 responses at week 12. The estimated probability of a positive treatment effect (ie, log odds ratio > 0) for low- or high-dose secukinumab compared to historical placebo is 1 (ie, 100%). For the low and high doses at week 12, the investigator global assessment 0/1 response rates were 78.6% and 83.3%, respectively, and the PASI-90 response rates were 69% and 76.2%, respectively. The PASI-75 response rate was 92.9% for both the doses. LIMITATIONS: This is an open-label study design without a control arm. CONCLUSION: Secukinumab dosing regimens were efficacious and well tolerated in pediatric patients with moderate to severe plaque psoriasis.

Health Resource Utilization Associated with Skeletal-Related Events in Patients with Advanced Prostate Cancer: A European Subgroup Analysis from an Observational, Multinational Study.

This study aimed to increase the understanding of health resource utilization (HRU) associated with skeletal-related events (SREs) occurring in patients with bone metastases secondary to advanced prostate cancer. A total of 120 patients from Germany, Italy, Spain and the United Kingdom were enrolled in this observational study. They had bone metastases secondary to prostate cancer and had experienced at least one SRE in the 97 days before giving informed consent. HRU data were collected retrospectively for 97 days before enrolment and prospectively for up to 18-21 months. HRU, including the number and duration of inpatient hospitalizations, number of outpatient and emergency department visits and procedures, was independently attributed by investigators to an SRE. Of the 222 SREs included in this analysis, 26% were associated with inpatient stays and the mean duration per SRE was 21.4 days (standard deviation (SD) 17.8 days). Overall, 174 SREs (78%) required an outpatient visit and the mean number of visits per SRE was 4.6 (SD 4.6). All SREs are associated with substantial HRU. Preventing SREs in patients with advanced prostate cancer and bone metastases may help to reduce the burden to both patients and European healthcare systems.

Health resource utilization associated with skeletal-related events in patients with advanced breast cancer: results from a prospective, multinational observational study.

Patients with breast cancer and bone metastases often experience skeletal complications (skeletal-related events [SREs]: pathologic fracture, radiation to bone, surgery to bone or spinal cord compression). Prospective data on the health resource burden of SREs are needed for planning healthcare requirements and estimating the value of new treatments, but limited data are available. This prospective, observational study collected health resource utilization (HRU) data independently attributed to SREs by investigators. Eligible patients had bone metastases secondary to breast cancer, life expectancy ≥6 months, Eastern Cooperative Oncology Group (ECOG) performance status ≤2, and at least one SRE in the 97 days before enrollment. Data, collected retrospectively for 97 days before enrollment and prospectively for 18-21 months, included number and duration of inpatient stays, outpatient visits, emergency room visits and procedures. Altogether, 223 patients were enrolled from Germany, Italy, Spain and the UK. Of the 457 SREs, 118 (25.8%) were associated with inpatient stays. The mean duration of stay was 19.5 (standard deviation [SD] 19.2) days per SRE (based on 117 SREs). Surgery to bone and spinal cord compression were the SREs most likely to require inpatient stays (77.8% and 57.9% of SREs, respectively), while radiation to bone was the least likely (9.7%). Spinal cord compression required the longest inpatient stay per event (34.2 [SD 30.2] days) and radiation to bone the shortest (14.3 [SD 10.2] days). Overall, 342 SREs (74.8%) required an outpatient visit, with radiation to bone the most likely (85.7%), and surgery to bone the least likely (42.6%). Radiation to bone was also associated with the greatest number of outpatient visits per event (6.8 [SD 6.7] visits). All SREs were associated with substantial HRU therefore, preventing SREs in patients with breast cancer may reduce the burden imposed on healthcare systems.

Denosumab compared with ibandronate in postmenopausal women previously treated with bisphosphonate therapy: a randomized open-label trial.

OBJECTIVE: To compare the efficacy and safety of denosumab to ibandronate in postmenopausal women with low bone mineral density (BMD) previously treated with a bisphosphonate. METHODS: In a randomized, open-label study, postmenopausal women received 60 mg denosumab subcutaneously every 6 months (n=417) or 150 mg ibandronate orally every month (n=416) for 12 months. End points included percentage change from baseline in total hip, femoral neck, and lumbar spine BMD at month 12 and percentage change from baseline in serum C-telopeptide at months 1 and 6 in a substudy. RESULTS: At month 12, significantly greater BMD gains from baseline were observed with denosumab compared with ibandronate at the total hip (2.3% compared with 1.1%), femoral neck (1.7% compared with 0.7%), and lumbar spine (4.1% compared with 2.0%; treatment difference P<.001 at all sites). At month 1, median change in serum C-telopeptide from baseline was -81.1% with denosumab and -35.0% with ibandronate (P<.001); the treatment difference remained significant at month 6 (P<.001). Adverse events occurred in 245 (59.6%) denosumab-treated women and 230 (56.1%) ibandronate-treated women (P=.635). The incidence of serious adverse events was 9.5% for denosumab-treated women and 5.4% for ibandronate-treated women (P=.046). No clustering of events in any organ system accounted for the preponderance of these reports. The incidence rates of serious adverse events involving infection and malignancy were similar between treatment groups. CONCLUSION: In postmenopausal women previously treated with a bisphosphonate and low BMD, denosumab treatment resulted in greater BMD increases than ibandronate at all measured sites. No new safety risks with denosumab treatment were identified.
