Romosozumab and antiresorptive treatment: the importance of treatment sequence.

To evaluate whether treatment sequence affects romosozumab response, this analysis reviewed studies where romosozumab was administered before or following an antiresorptive (alendronate or denosumab). Initial treatment with romosozumab followed by an antiresorptive resulted in larger increases in bone mineral density of both hip and spine compared with the reverse sequence. INTRODUCTION: Teriparatide followed by an antiresorptive increases bone mineral density (BMD) more than using an antiresorptive first. To evaluate whether treatment sequence affects romosozumab response, we reviewed randomized clinical trials where romosozumab was administered before (ARCH, FRAME) or following (STRUCTURE, Phase 2 extension) an antiresorptive (alendronate or denosumab, respectively). METHODS: We evaluated BMD percentage change for total hip (TH) and lumbar spine (LS) and response rates (BMD gains ≥ 3% and ≥ 6%) at years 1 and 2 (except STRUCTURE with only 1-year data available). RESULTS: With 1-year romosozumab initial therapy in ARCH and FRAME, TH BMD increased 6.2% and 6.0%, and LS BMD increased 13.7% and 13.1%, respectively. When romosozumab was administered for 1 year after alendronate (STRUCTURE) or denosumab (Phase 2 extension), TH BMD increased 2.9% and 0.9%, respectively, and LS BMD increased 9.8% and 5.3%, respectively. Over 2 years, TH and LS BMD increased 7.1% and 15.2% with romosozumab/alendronate, 8.5% and 16.6% with romosozumab/denosumab, and 3.8% and 11.5% with denosumab/romosozumab, respectively. A greater proportion of patients achieved BMD gains ≥ 6% when romosozumab was used first, particularly for TH, versus the reverse sequence (69% after romosozumab/denosumab; 15% after denosumab/romosozumab). CONCLUSION: In this study, larger mean BMD increases and greater BMD responder rates were achieved when romosozumab was used before, versus after, an antiresorptive agent. Since BMD on treatment is a strong surrogate for bone strength and fracture risk, this analysis supports the thesis that initial treatment with romosozumab followed by an antiresorptive will result in greater efficacy versus the reverse sequence.

Correction to: Relationship between P1NP, a biochemical marker of bone turnover, and bone mineral density in patients transitioned from alendronate to romosozumab or teriparatide: a post hoc analysis of the STRUCTURE trial.

In the original publication of the article, the last row of Table 1 was published incorrectly as "Serum P1NP (µmol/L), median (IQR)b : Romosozumab, 25 (18, 34); Teriparatide, 25 (20, 33)". The correct row should be read as "Serum P1NP (µg/L), median (IQR)b : Romosozumab, 25 (18, 34); Teriparatide, 25 (20, 33)".

Relationship between P1NP, a biochemical marker of bone turnover, and bone mineral density in patients transitioned from alendronate to romosozumab or teriparatide: a post hoc analysis of the STRUCTURE trial.

INTRODUCTION: Procollagen type I N-terminal propeptide (P1NP), a bone formation marker, reportedly predicts bone mineral density (BMD) response to teriparatide treatment in treatment-naive patients with osteoporosis. Results from a randomized, phase 3, open-label, active-controlled trial- STRUCTURE-showed that in patients previously treated with bisphosphonates, romosozumab led to gains in hip BMD, which were not observed with teriparatide. This post hoc analysis investigated the comparative utility of early changes in P1NP in predicting BMD response in patients who participated in the STRUCTURE trial, which enrolled patients who switched treatment from bisphosphonates to romosozumab/teriparatide. MATERIALS AND METHODS: Postmenopausal women (aged 55-90 years) with osteoporosis who had previously taken bisphosphonates were randomized to receive open-label subcutaneous romosozumab (210 mg once monthly; n = 218) or teriparatide (20 µg once daily; n = 218) for 12 months. BMD was assessed by dual-energy X-ray absorptiometry at the proximal femur and lumbar spine (LS) at baseline and months 6 and 12. To assess the utility of P1NP, the positive predictive value of increase from baseline in P1NP of > 10 µg/L at month 1 and achievement of various thresholds of percent change from baseline in BMD at month 12 were evaluated. RESULTS: Overall, 95% (191/202) of patients in the romosozumab group and 91% (183/201) in the teriparatide group demonstrated an increase in P1NP of > 10 µg/L from baseline at month 1. Among these patients, 18% and 3% of romosozumab-treated patients versus 60% and 12% of teriparatide-treated patients showed no increase from baseline (i.e., ≤ 0%) in total hip and LS BMD, respectively, at month 12. These data indicate that in patients switching from bisphosphonates to a bone-forming therapy, increases in P1NP do not help predict the hip BMD response. Although most patients treated with either teriparatide or romosozumab showed an increase in P1NP, the majority of patients on romosozumab showed an increase in hip BMD, while more than half of the patients on teriparatide did not. Teriparatide therapy did not increase total hip BMD in the majority of patients who transitioned from bisphosphonates to teriparatide. CONCLUSIONS: Thus, increases in P1NP were not predictive of BMD response in the teriparatide group because in approximately 60% of the patients who were administered teriparatide, the hip BMD decreased independent of the change in P1NP levels.

Romosozumab Treatment in Postmenopausal Women with Osteoporosis.

BACKGROUND: Romosozumab, a monoclonal antibody that binds sclerostin, increases bone formation and decreases bone resorption. METHODS: We enrolled 7180 postmenopausal women who had a T score of -2.5 to -3.5 at the total hip or femoral neck. Patients were randomly assigned to receive subcutaneous injections of romosozumab (at a dose of 210 mg) or placebo monthly for 12 months; thereafter, patients in each group received denosumab for 12 months, at a dose of 60 mg, administered subcutaneously every 6 months. The coprimary end points were the cumulative incidences of new vertebral fractures at 12 months and 24 months. Secondary end points included clinical (a composite of nonvertebral and symptomatic vertebral) and nonvertebral fractures. RESULTS: At 12 months, new vertebral fractures had occurred in 16 of 3321 patients (0.5%) in the romosozumab group, as compared with 59 of 3322 (1.8%) in the placebo group (representing a 73% lower risk with romosozumab; P<0.001). Clinical fractures had occurred in 58 of 3589 patients (1.6%) in the romosozumab group, as compared with 90 of 3591 (2.5%) in the placebo group (a 36% lower risk with romosozumab; P=0.008). Nonvertebral fractures had occurred in 56 of 3589 patients (1.6%) in the romosozumab group and in 75 of 3591 (2.1%) in the placebo group (P=0.10). At 24 months, the rates of vertebral fractures were significantly lower in the romosozumab group than in the placebo group after each group made the transition to denosumab (0.6% [21 of 3325 patients] in the romosozumab group vs. 2.5% [84 of 3327] in the placebo group, a 75% lower risk with romosozumab; P<0.001). Adverse events, including instances of hyperostosis, cardiovascular events, osteoarthritis, and cancer, appeared to be balanced between the groups. One atypical femoral fracture and two cases of osteonecrosis of the jaw were observed in the romosozumab group. CONCLUSIONS: In postmenopausal women with osteoporosis, romosozumab was associated with a lower risk of vertebral fracture than placebo at 12 months and, after the transition to denosumab, at 24 months. The lower risk of clinical fracture that was seen with romosozumab was evident at 1 year. (Funded by Amgen and UCB Pharma; FRAME ClinicalTrials.gov number, NCT01575834 .).

Phase 3 Studies Comparing Brodalumab with Ustekinumab in Psoriasis.

BACKGROUND: Early clinical studies suggested that the anti-interleukin-17 receptor A monoclonal antibody brodalumab has efficacy in the treatment of psoriasis. METHODS: In two phase 3 studies (AMAGINE-2 and AMAGINE-3), patients with moderate-to-severe psoriasis were randomly assigned to receive brodalumab (210 mg or 140 mg every 2 weeks), ustekinumab (45 mg for patients with a body weight ≤100 kg and 90 mg for patients >100 kg), or placebo. At week 12, patients receiving brodalumab were randomly assigned again to receive a brodalumab maintenance dose of 210 mg every 2 weeks or 140 mg every 2 weeks, every 4 weeks, or every 8 weeks; patients receiving ustekinumab continued to receive ustekinumab every 12 weeks, and patients receiving placebo received 210 mg of brodalumab every 2 weeks. The primary aims were to evaluate the superiority of brodalumab over placebo at week 12 with respect to at least a 75% reduction in the psoriasis area-and-severity index score (PASI 75) and a static physician's global assessment (sPGA) score of 0 or 1 (clear or almost clear skin), as well as the superiority of brodalumab over ustekinumab at week 12 with respect to a 100% reduction in PASI score (PASI 100). RESULTS: At week 12, the PASI 75 response rates were higher with brodalumab at the 210-mg and 140-mg doses than with placebo (86% and 67%, respectively, vs. 8% [AMAGINE-2] and 85% and 69%, respectively, vs. 6% [AMAGINE-3]; P<0.001); the rates of sPGA scores of 0 or 1 were also higher with brodalumab (P<0.001). The week 12 PASI 100 response rates were significantly higher with 210 mg of brodalumab than with ustekinumab (44% vs. 22% [AMAGINE-2] and 37% vs. 19% [AMAGINE-3], P<0.001). The PASI 100 response rates with 140 mg of brodalumab were 26% in AMAGINE-2 (P=0.08 for the comparison with ustekinumab) and 27% in AMAGINE-3 (P=0.007). Rates of neutropenia were higher with brodalumab and with ustekinumab than with placebo. Mild or moderate candida infections were more frequent with brodalumab than with ustekinumab or placebo. Through week 52, the rates of serious infectious episodes were 1.0 (AMAGINE-2) and 1.3 (AMAGINE-3) per 100 patient-years of exposure to brodalumab. CONCLUSIONS: Brodalumab treatment resulted in significant clinical improvements in patients with moderate-to-severe psoriasis.

Measurement Properties of the Psoriasis Symptom Inventory Electronic Daily Diary in Patients with Moderate to Severe Plaque Psoriasis.

OBJECTIVES: The Psoriasis Symptom Inventory (PSI) is a patient-reported outcome instrument that measures the severity of psoriasis signs and symptoms. This study evaluated measurement properties of the PSI in patients with moderate to severe plaque psoriasis. METHODS: This secondary analysis used pooled data from a phase 3 brodalumab clinical trial (AMAGINE-1). Outcome measures included the PSI, Psoriasis Area and Severity Index (PASI), static Physician's Global Assessment (sPGA), psoriasis-affected body surface area, 36-item Short-Form Health Survey version 2, and the Dermatology Life Quality Index (DLQI). The PSI was evaluated for dimensionality, item performance, reliability (internal consistency and test-retest), construct validity, ability to detect change, and agreement between PSI response and response measures based on the PASI, sPGA, and DLQI. RESULTS: Results supported unidimensionality, good item fit, ordered responses, and PSI scoring. The PSI demonstrated reliability: baseline Cronbach's alpha ≥ 0.92 and intraclass correlation coefficients ≥ 0.95. Correlations between PSI total score and DLQI item 1 (r = 0.86), DLQI symptoms and feelings (r = 0.87), and 36-item Short-Form Health Survey version 2 bodily pain (r = -0.61) supported convergent validity. PSI scores differed significantly (P < 0.001) among severity groups based on the PASI (< 12/≥ 12), sPGA (0-1/2-3/4-5), body surface area (< 5%/5%-10%/> 10%), and DLQI (≤ 5/> 5) at weeks 8 and 12. At week 12, the PSI detected significant changes in severity based on PASI responses (< 50/50- < 75/≥ 75) and sPGA (0-1/≥ 2), and showed good agreement (k ≥ 0.66) between PSI response and PASI, sPGA, and DLQI responses. CONCLUSION: The PSI demonstrated excellent validity, reliability, and ability to detect change in the severity of psoriasis signs and symptoms.

Clinical meaningfulness of complete skin clearance in psoriasis.

BACKGROUND: New psoriasis therapies have increased the ability to achieve skin clearance. However, insufficient evidence exists on the impact of total skin clearance from the patient perspective. OBJECTIVE: We sought to determine if complete skin clearance is clinically meaningful compared with treatment responses without clearance. METHODS: Pooled data from 3 phase-III trials were used to compare results for patients with complete skin clearance (Psoriasis Area and Severity Index [PASI] 100 or static Physician Global Assessment score 0) with patients without complete skin clearance (PASI 75 to <100 or static Physician Global Assessment score 1) based on Psoriasis Symptom Inventory and Dermatology Life Quality Index. RESULTS: Percentages of patients with Psoriasis Symptom Inventory score 0 were 45% for those achieving PASI 100 and 8% for PASI 75 to <100 (P < .001). Respective percentages with Dermatology Life Quality Index score 0/1 were 80% and 55% (P < .001). PASI 100 resulted in incremental improvement over PASI 90 to <100 (incremental differences of 28% for Psoriasis Symptom Inventory score 0 and 18% for Dermatology Life Quality Index score 0). Similar results were observed for static Physician Global Assessment scores 0 versus 1. CONCLUSIONS: Complete skin clearance represents a clinically meaningful end point and outcome for patients, reflected in experiences of no psoriasis symptoms and no impairment on health-related quality of life.

Efficacy and safety of brodalumab in subpopulations of patients with difficult-to-treat moderate-to-severe plaque psoriasis.

BACKGROUND: Novel therapies are needed for difficult-to-treat populations of patients with psoriasis. OBJECTIVE: We sought to assess the efficacy and safety of the interleukin-17 Receptor A inhibitor brodalumab in patients with psoriasis with or without a self-reported history of psoriatic arthritis (PsA) and with or without a history of biologic use. METHODS: Subset analyses of a phase II, randomized, double-blind, placebo-controlled study of brodalumab in patients with moderate-to-severe plaque psoriasis were performed. Improvement from baseline in Psoriasis Area and Severity Index score of 75%, 90%, and 100% at week 12; static Physician Global Assessment (0/1) score; Dermatology Life Quality Index response; and Psoriasis Symptom Inventory response were evaluated within subgroups. RESULTS: Efficacy and quality-of-life measures were generally similar between subgroups of patients with or without a history of PsA and with or without a history of biologic use across brodalumab doses and were significantly higher among patients who received brodalumab 140 mg every 2 weeks or 210 mg every 2 weeks versus placebo. LIMITATIONS: Differences between subgroups were not compared statistically, PsA was self-reported, only skin involvement/symptoms were reported, and reasons for discontinuation of prior biologic were not captured. CONCLUSION: Brodalumab is efficacious in patients with psoriasis with or without a history of PsA or biologic use.

Safety and efficacy of brodalumab for psoriasis after 120 weeks of treatment.

BACKGROUND: Brodalumab (anti-interleukin-17-receptor antibody) was effective in treating moderate to severe psoriasis in a 12-week, dose-ranging, placebo-controlled trial. OBJECTIVE: We sought to evaluate efficacy and safety of long-term brodalumab treatment. METHODS: In this interim analysis at week 120 of an open-label extension study, patients received brodalumab 210 mg every 2 weeks. Protocol amendments reduced the dose (140 mg) in patients weighing 100 kg or less and subsequently increased the dose (210 mg) in patients with inadequate responses. Efficacy was measured by static physician global assessment and 75% or greater, 90% or greater, or 100% improvement in Psoriasis Area and Severity Index score (PASI-75, PASI-90, and PASI-100, respectively). RESULTS: Of 181 patients, 144 completed week 120. Static physician global assessment scores of clear/almost clear and clear were achieved by 90% and 63% of patients, respectively, at week 12 and by 72% and 51% at week 120. The PASI-75, PASI-90, and PASI-100 response rates at week 12 (95%/85%/63%) were sustained through week 120 (86%/70%/51%). Most commonly reported adverse events were nasopharyngitis (26.5%), upper respiratory tract infection (19.9%), arthralgia (16.0%), and back pain (11.0%). Four patients had grade-2 absolute neutrophil count. LIMITATIONS: There was no control group in this open-label extension. CONCLUSION: Brodalumab demonstrated sustained clinical response and an acceptable safety profile through 120 weeks in patients with moderate to severe psoriasis.

Improving resource utilisation in SLE drug development through innovative trial design.

SLE is a complex autoimmune disease with considerable unmet need. Numerous clinical trials designed to investigate novel therapies are actively enrolling patients straining limited resources and creating inefficiencies that increase enrolment challenges. This has motivated investigators developing novel drugs and treatment strategies to consider innovative trial designs that aim to improve the efficiency of generating evidence; these strategies propose conducting fewer trials, involving smaller numbers of patients, while maintaining scientific rigour in safety and efficacy data collection and analysis. In this review we present the design of two innovative phase IIb studies investigating efavaleukin alfa and rozibafusp alfa for the treatment of SLE which use an adaptive study design. This design was selected as a case study, investigating efavaleukin alfa, in the Food and Drug Administration's Complex Innovative Trial Design Pilot Program. The adaptive design approach includes prospectively planned modifications at predefined interim timepoints. Interim assessments of futility allow for a trial to end early when the investigational therapy is unlikely to provide meaningful treatment benefits to patients, which can release eligible patients to participate in other-potentially more promising-trials, or seek alternative treatments. Response-adaptive randomisation allows randomisation ratios to change based on accumulating data, in favour of the more efficacious dose arm(s), while the study is ongoing. Throughout the trial the placebo arm allocation ratio is maintained constant. These design elements can improve the statistical power in the estimation of treatment effect and increase the amount of safety and efficacy data collected for the optimal dose(s). Furthermore, these trials can provide the required evidence to potentially serve as one of two confirmatory trials needed for regulatory approval. This can reduce the need for multiple phase III trials, the total patient requirements, person-exposure risk, and ultimately the time and cost of investigational drug development programmes.

The Effect of 1 Year of Romosozumab on the Incidence of Clinical Vertebral Fractures in Postmenopausal Women With Osteoporosis: Results From the FRAME Study.

Radiographic vertebral fractures (VFxs) are the most common fractures in osteoporosis and are associated with increased morbidity, mortality, and costs. A subset of VFxs manifest clinically, usually with a sudden onset of severe back pain. Romosozumab is a monoclonal antibody that binds and inhibits sclerostin, increasing bone formation and decreasing bone resorption, leading to rapid and large increases in bone density and strength and reduction in fracture risk. The FRAME (Fracture Study in Postmenopausal Women with Osteoporosis) study of postmenopausal women with osteoporosis demonstrated a significant reduction in new VFxs with romosozumab versus placebo. Here, we report the effect of romosozumab versus placebo on clinical VFx incidence over 12 months in women reporting back pain suggestive of VFxs. FRAME enrolled 7180 postmenopausal women with osteoporosis, mean age 70.9 years (hip T-score -2.5 to -3.5). In the first year of the study, women received monthly romosozumab 210 mg (n = 3589) or placebo (n = 3591). At regular monthly visits, women reporting back pain suggestive of a clinical VFx had a confirmatory spine X-ray. Clinical VFx risk in the romosozumab group versus the placebo group was calculated by Cox-proportional hazards model. Of 119 women in FRAME with back pain suggestive of a clinical VFx over 12 months, 20 were confirmed to have experienced a new/worsening VFx. Three women receiving romosozumab had a clinical VFx (<0.1% of 3589 women) versus 17 (0.5% of 3591 women) receiving placebo resulting in a reduction in clinical VFx risk of 83% in the romosozumab group versus placebo through 12 months (HR 0.17; 95% CI, 0.05 to 0.58; p = 0.001). In the three romosozumab-treated women, clinical VFxs occurred within the first 2 months of the study with no further clinical VFxs throughout the year. Romosozumab treatment for 12 months was associated with rapid and large reductions in clinical VFx risk versus placebo. © 2019 The Authors.

One Year of Romosozumab Followed by Two Years of Denosumab Maintains Fracture Risk Reductions: Results of the FRAME Extension Study.

Romosozumab, a humanized monoclonal antibody that binds and inhibits sclerostin, has the dual effect of increasing bone formation and decreasing bone resorption. As previously reported in the pivotal FRActure study in postmenopausal woMen with ostEoporosis (FRAME), women with a T-score of ≤ -2.5 at the total hip or femoral neck received subcutaneous placebo or romosozumab once monthly for 12 months, followed by open-label subcutaneous denosumab every 6 months for an additional 12 months. Upon completion of the 24-month primary analysis period, eligible women entered the extension phase and received denosumab for an additional 12 months. Here, we report the final analysis results through 36 months, including efficacy assessments of new vertebral, clinical, and nonvertebral fracture; bone mineral density (BMD); and safety assessments. Of 7180 women enrolled, 5743 (80%) completed the 36-month study (2851 romosozumab-to-denosumab; 2892 placebo-to-denosumab). Through 36 months, fracture risk was reduced in subjects receiving romosozumab versus placebo for 12 months followed by 24 months of denosumab for both groups: new vertebral fracture (relative risk reduction [RRR], 66%; incidence, 1.0% versus 2.8%; p < 0.001), clinical fracture (RRR, 27%; incidence, 4.0% versus 5.5%; p = 0.004), and nonvertebral fracture (RRR, 21%; incidence, 3.9% versus 4.9%; p = 0.039). BMD continued to increase for the 2 years with denosumab treatment in both arms. The substantial difference in BMD achieved through 12 months of romosozumab treatment versus placebo was maintained through the follow-up period when both treatment arms received denosumab. Subject incidence of adverse events, including positively adjudicated serious cardiovascular adverse events, were overall balanced between groups. In conclusion, in postmenopausal women with osteoporosis, 12 months of romosozumab led to persistent fracture reduction benefit and ongoing BMD gains when followed by 24 months of denosumab. The sequence of romosozumab followed by denosumab may be a promising regimen for the treatment of osteoporosis. © 2018 American Society for Bone and Mineral Research.

Romosozumab FRAME Study: A Post Hoc Analysis of the Role of Regional Background Fracture Risk on Nonvertebral Fracture Outcome.

In the pivotal Fracture Study in Postmenopausal Women with Osteoporosis (FRAME; NCT01575834), 1 year of the bone-forming agent romosozumab significantly reduced new vertebral and clinical fracture risk versus placebo. Nonvertebral fracture risk was not significantly reduced in the overall population, influenced by a low placebo-group fracture rate, observed particularly in the highest-enrolling region of Latin America. In year 1 of FRAME, postmenopausal women with a T-score of -2.5 to -3.5 at the total hip or femoral neck were randomized to subcutaneous romosozumab 210 mg or placebo once monthly for 12 months. Of 7180 randomized women, 43% were from Latin America, largely Colombia and Brazil. Prespecified analyses assessed fracture risk reductions by geographic regions. A significant treatment-by-geographic region interaction for the clinical (p = 0.029) and nonvertebral fracture (p = 0.042) endpoints led to further characterization of the Latin American population and comparison with the remaining study population, grouped post hoc as rest-of-world. Nonvertebral fracture efficacy in the overall population was also assessed by baseline fracture risk using the Fracture Risk Assessment Tool (FRAX). Romosozumab significantly and consistently reduced new vertebral fracture risk in Latin America (70% reduction; p = 0.014) and rest-of-world (74% reduction; p < 0.001). For nonvertebral fracture, risk reductions were observed in rest-of-world (42% reduction; p = 0.012), with no treatment effect observed in Latin America, where background nonvertebral fracture risk was low (1.2% in the placebo group). Consistent with this finding, in the overall population, greater reductions in nonvertebral fracture risk were observed among women with higher FRAX scores. These findings suggest that fracture risk assessment should consider regional factors in addition to classical risk factors, such as bone mineral density. In women at high risk for fracture, romosozumab reduced nonvertebral fracture risk within 1 year. © 2018 The Authors. Journal of Bone and Mineral Research Published by Wiley Periodicals, Inc.

FRAME Study: The Foundation Effect of Building Bone With 1 Year of Romosozumab Leads to Continued Lower Fracture Risk After Transition to Denosumab.

Romosozumab is a bone-forming agent with a dual effect of increasing bone formation and decreasing bone resorption. In FRActure study in postmenopausal woMen with ostEoporosis (FRAME), postmenopausal women with osteoporosis received romosozumab 210 mg s.c. or placebo once monthly for 12 months, followed by denosumab 60 mg s.c. once every 6 months in both groups for 12 months. One year of romosozumab increased spine and hip BMD by 13% and 7%, respectively, and reduced vertebral and clinical fractures with persistent fracture risk reduction upon transition to denosumab over 24 months. Here, we further characterize the BMD gains with romosozumab by quantifying the percentages of patients who responded at varying magnitudes; report the mean T-score changes from baseline over the 2-year study and contrast these results with the long-term BMD gains seen with denosumab during Fracture REduction Evaluation of Denosumab in Osteoporosis every 6 Months (FREEDOM) and its Extension studies; and assess fracture incidence rates in year 2, when all patients received denosumab. Among 7180 patients (n = 3591 placebo, n = 3589 romosozumab), most romosozumab-treated patients experienced ≥3% gains in BMD from baseline at month 12 (spine, 96%; hip, 78%) compared with placebo (spine, 22%; hip, 16%). For romosozumab patients, mean absolute T-score increases at the spine and hip were 0.88 and 0.32, respectively, at 12 months (placebo: 0.03 and 0.01) and 1.11 and 0.45 at 24 months (placebo-to-denosumab: 0.38 and 0.17), with the 2-year gains approximating the effect of 7 years of continuous denosumab administration. Patients receiving romosozumab versus placebo in year 1 had significantly fewer vertebral fractures in year 2 (81% relative reduction; p < 0.001), with fewer fractures consistently observed across other fracture categories. The data support the clinical benefit of rebuilding the skeletal foundation with romosozumab before transitioning to antiresorptive therapy. © 2018 The Authors.

Total skin clearance results in improvements in health-related quality of life and reduced symptom severity among patients with moderate to severe psoriasis.

BACKGROUND: Newer therapies provide high levels of skin clearance in patients with moderate to severe psoriasis. However, insufficient evidence exists on the impact of total skin clearance from the patient's perspective. OBJECTIVES: To examine effects of total skin clearance on health-related quality of life (HRQoL) and psoriasis symptom severity in subjects with moderate to severe psoriasis. METHODS: Pooled data from a phase 2 dose-ranging trial in psoriasis using brodalumab (antibody to interleukin-17 receptor A) were used to compare subjects with static physician global assessment (sPGA) 1 versus sPGA 0 and subjects with Psoriasis Area and Severity Index (PASI) 75 to <100 versus PASI 100 at week 12 based on no impairment in Dermatology Life Quality Index (DLQI = 0) and no psoriasis symptoms (Psoriasis Symptom Inventory = 0). RESULTS: Of subjects with sPGA 0 (clear) and 1 (almost clear), 61.4% and 45.7% had a DLQI = 0 (p = 0.15), and 65.5% and 32.6% had a Psoriasis Symptom Inventory = 0 (p = 0.001), respectively. Significantly more subjects with sPGA 1 continued to report itching, redness, scaling, and flaking compared to subjects with sPGA 0. Similar results were observed based on PASI score. CONCLUSIONS: A higher proportion of subjects with total skin clearance reported no impairment in HRQoL and no psoriasis symptoms than those who were almost clear.
