Abstract
BACKGROUND Historically, pediatric medicines are developed after adult trials are completed, even when identical drug targets and disease similarities exist across the populations. This has resulted in significant delays in the authorization of medicines for adolescent use, limiting access to beneficial drugs. This study sought to understand how adolescent inclusion in adult trials is positioned in regulatory guidance documents as they set critical expectations for trial design and regulatory decision-making. METHODS This study utilized a qualitative analysis approach. Guidance documents were identified via Food and Drug Administration and European Medicines Agency websites. Utilizing a blinded adjudication process, the documents were classified as permissive, exclusionary, or silent regarding recommendations about adolescent inclusion in adult clinical trials. A post hoc analysis of similarities and differences between the Food and Drug Administration and European Medicines Agency guidance documents was conducted to assess the possible role of regional pediatric research laws on age-inclusive trial methodologies as well as emergent themes by therapeutic area. RESULTS In total, 96 Food and Drug Administration (1977 to 2019) and 106 European Medicines Agency (1987 to 2019) guidance documents were identified for analysis. The guidance contained explicit or implicit recommendations supporting adolescent inclusion in adult trials in 32% of Food and Drug Administration and 15% of European Medicines Agency documents, while 14% and 21%, respectively, were found to be exclusionary. A large number of guidance documents were silent regarding the applicability of adolescent-inclusive trial designs (53% and 64%, Food and Drug Administration and European Medicines Agency, respectively). Analysis by therapeutic area revealed the most permissive of adolescent inclusion in Food and Drug Administration guidance for infectious diseases and conditions requiring blood products in European Medicines Agency guidance. A more holistic approach to age-inclusive trial design was identified in disease guidance published by the Food and Drug Administration Oncology Center of Excellence. DISCUSSION There are many influences on the development and/or revision of regulatory guidance documents. Substantial scientific knowledge and regulatory precedence for the inclusion of adolescents within adult trials are available to inform research approaches. Our study has identified important opportunities for the enhancement of guidance. For example, contextualization of developmental factors influencing adolescent disease progression provides insights into the role of adolescent inclusion. If addressed, guidance documents can facilitate broader acceptance of age-inclusive trial methodologies and accelerate adolescent access to medicines.

Abstract
Clinical trials to address the COVID-19 public health emergency have broadly excluded pregnant people from participation, illustrating a long-standing trend of clinical trial exclusion that has led to a clear knowledge gap and unmet need in the treatment and prevention of medical conditions experienced during pregnancy and of pregnancy-related conditions. Drugs (includes products such as drugs, biologics, biosimilars and vaccines) approved for a certain medical condition in adults are also approved for use in pregnant adults with the same medical condition, unless contraindicated for use in pregnancy. However, there are limited pregnancy-specific data on risks and benefits of drugs in pregnant people, despite their approval for all adults. The United States Food and Drug Administration-approved medical products are used widely by pregnant people, 90% of whom take at least 1 medication during the course of their pregnancy despite there being sparse data from clinical trials on these products in pregnancy. This overall lack of clinical data precludes informed decision-making, causing clinicians and pregnant patients to have to decide whether to pursue treatment without an adequate understanding of potential effects. Although some United States Food and Drug Administration initiatives and other federal efforts have helped to promote the inclusion of pregnant people in clinical research, broader collaboration and reforms are needed to address challenges related to the design and conduct of trials that enroll pregnant people, and to forge a culture of widespread inclusion of pregnant people in clinical research. This article summarizes the scientific, ethical, and legal considerations governing research conducted during pregnancy, as discussed during a recent subject matter expert convening held by the Duke-Margolis Center for Health Policy and the United States Food and Drug Administration on this topic. This article also recommends strategies for overcoming impediments to inclusion and trial conduct.

Abstract
OBJECTIVE To assess the perspectives of neonatologists, neonatal nurses, and parents on research-related education and communication practices in the neonatal intensive care unit (NICU). STUDY DESIGN Questionnaire circulated through interest groups and administered using the internet. RESULTS 323 respondents responded to the survey. 52 were neonatologists, 188 were neonatal nurses, and 83 were parents of NICU graduates. Analysis was descriptive. Differences were noted between stakeholder groups with respect to whether current medications meet the needs of sick neonates, research as central to the mission of the NICU, availability of appropriate education/training for all members of the research team, and adequacy of information provided to parents before, during, and after a research study is completed. CONCLUSION Engagement of nurses and parents at all stages of NICU research is currently suboptimal; relevant good practices, including education, should be shared among neonatal units.

Abstract
Including adolescents in adult clinical trials can play an important role in making innovative new medicines available to children in a timelier fashion. Stakeholders involved in the processes leading to regulatory approval and labeling of new drugs recognize that challenges exist in involving adolescents and older children in clinical trials before the safety and efficacy of these drugs are established for adults. However, it has been possible to design and execute phase 3 trials that combine adults with adolescents which are medically and scientifically sound and ethically justified. Based on this experience and considerations of the medical and scientific, ethical, and operation-related matters, the 2019 Pediatric Innovation Research Forum advocated for the position that adolescents routinely be considered for enrollment in phase 3 clinical trials. The Forum also concluded that exclusion of adolescents in adult pivotal trials occur only when a thorough evaluation of the target disease and the potential benefit and risks of the study intervention supports a delay in their involvement until after completion of clinical trials in adults.

Abstract
Rare or orphan diseases often are inherited and overwhelmingly affect children. Many of these diseases have no treatments, are incurable, and have a devastating impact on patients and their families. Regulatory standards for drug approval for rare diseases must ensure that patients receive safe and efficacious treatments. However, regulatory bodies have shown flexibility in applying these standards to drug development in rare diseases, given the unique challenges that hinder efficient and effective traditional clinical trials, including low patient numbers, limited understanding of disease pathology and progression, variability in disease presentation, and a lack of established endpoints. To take steps toward improving rare disease clinical development strategies under current global regulatory statutes, Amicus Therapeutics, Inc. and BioNJ convened a 1-day meeting that included representatives from the Food and Drug Administration (FDA), biopharmaceutical industry, and not-for-profit agencies. The meeting focused on orphan diseases in pediatric and adult patients and was intended to identify potential strategies to overcome regulatory hurdles through open collaboration. During this meeting, several strategies were identified to minimize the limitations associated with low patient numbers in rare diseases, including the use of natural history to generate historical control data in comparisons, simulations, and identifying inclusion/exclusion criteria and appropriate endpoints. Novel approaches to clinical trial design were discussed to minimize patient exposure to placebo and to reduce the numbers of patients and clinical trials needed for providing substantial evidence. Novel statistical analysis approaches were also discussed to address the inherent challenges of small patient numbers. Areas of urgent unmet need were identified, including the need to develop registries that protect patient identities, to establish close collaboration and communication between the sponsor and regulatory bodies to address methodological and statistical challenges, to collaborate in pre-competitive opportunities within multiple sponsors and in conjunction with academia and disease-specific patient advocacy groups for optimal data sharing, and to develop harmonized guidelines for data extrapolation from source to target pediatric populations. Ultimately, these innovations will help in solving many regulatory challenges in rare disease drug development and encourage the availability of new treatments for patients with rare diseases.

Abstract
Health care professionals involved in the clinical management of children have long appreciated the limited number of therapies suitably evaluated for their optimal use in the pediatric population. In the past century, advances in regulatory policy significantly evolved adult drug evaluation. The scarcity of available patient populations, practical complexities of drug development research, and minimal financial returns have hampered pharmaceutical investment in the study of therapies for children. More recently, pediatric policy and legislation in the United States and Europe have instituted a system of obligations and incentives to stimulate investment in pediatric drug development. These initiatives, in conjunction with a more sophisticated process of drug discovery and development, have led to significant advancements in the labeling of drugs for pediatric use. Facilitated by the emergence of new targets, precision medicine, and innovations in regulatory science, there is now a subtle shift in focus toward drug development research for children rather than simply in children. Although there has been an increase in pediatric studies of investigational agents and labeling of pediatric information for use, there have been unintended consequences of existing policies. As a result, limited progress has been made in certain therapeutic areas and for off-patent therapies. Future policy reform to enhance the availability and accessibility of pediatric medicines should not only reflect an understanding not only of the successes of existing policy and legislative initiatives but also constructively address failures and unintended consequences. Taken together, policy reform, global cooperation, and innovation in regulatory science will more ably deliver better pediatric therapies tomorrow.

Abstract
Minimizing post-fracture bone loss is an important aspect of recovery from hip fracture, and determination of factors that affect bone mineral density (BMD) response to treatment after hip fracture may assist in the development of targeted therapeutic interventions. A post hoc analysis of the HORIZON Recurrent Fracture Trial was done to determine the effect of zoledronic acid (ZOL) on total hip (TH) and femoral neck (FN) BMD in subgroups with low-trauma hip fracture. A total of 2127 patients were randomized (1:1) to yearly infusions of ZOL 5 mg (n = 1065) or placebo (n = 1062) within 90 days of operation for low-trauma hip fracture. The 1486 patients with a baseline and at least one post-baseline BMD assessment at TH or FN (ZOL = 745, placebo = 741) were included in the analyses. Percentage change from baseline in TH and FN BMD was assessed at months 12 and 24 and compared across subgroups of hip fracture patients. Percentage change from baseline in TH and FN BMD at months 12 and 24 was greater (p < 0.05) in ZOL-treated patients compared with placebo in most subgroups. Treatment-by-subgroup interactions (p < 0.05) indicated that a greater effect on BMD was observed for TH BMD at month 12 in females, in patients in the lower tertile body mass index at baseline (≤22.6 kg/m(2) ), and in patients with baseline FN BMD T-score of ≤ -2.5; for FN BMD in patients who received ZOL for >6 weeks post-surgery; and for TH and FN BMD in patients with a history of one or more prior fractures. All interactions were limited to the first 12 months after treatment with none observed for the 24-month comparisons. (Clinical trial registration number NCT00046254.)

Abstract
CONTEXT Annual infusions of zoledronic acid 5 mg over 3 years have been shown to reduce fracture incidence. There is now evidence that the effects of a single dose of zoledronic acid on bone mineral density and bone turnover last for much more than a year. Whether this is associated with sustained fracture prevention is not known. OBJECTIVE The objective of the study was to assess fracture incidence after only 1 infusion of zoledronic acid. DESIGN The design of the study included post hoc analysis of subgroups of subjects from 2 trials, who received only 1 study infusion. SETTING The study included multicenter, randomized controlled trials. PARTICIPANTS A total of 1367 subjects from HORIZON-PFT and HORIZON-RFT studies who received only 1 of the planned annual infusions participated in the study. INTERVENTION The intervention of the study consisted of 1 infusion of zoledronic acid or placebo. MAIN OUTCOME MEASURE Clinical fracture was the main outcome measure of the study. RESULTS Mean follow-up period was 1.5 years. In patients who received only a single infusion, there was a 32% reduction in clinical fracture comparing zoledronic acid with placebo over 3 years of follow-up (95% confidence interval 2-53%, P = .04), comparable with the fracture reduction seen in those who had 3 or more annual infusions (34%; 95% confidence interval, 23-43%, P < .0001). New morphometric vertebral fractures were reduced by 68% in the single-infusion group (P = .004). The between-group differences in total hip bone mineral density at 3 years were 3.8% in those receiving 1 infusion and 6.2% in those receiving 3 infusions. CONCLUSIONS In this post hoc analysis based on postrandomization subgroups, fracture risk appears to be reduced for more than 1 year after a single infusion of zoledronic acid. Prospective studies designed to assess this possibility are now warranted.

Abstract
BACKGROUND Fractures in men are a major health issue, and data on the antifracture efficacy of therapies for osteoporosis in men are limited. We studied the effect of zoledronic acid on fracture risk among men with osteoporosis. METHODS In this multicenter, double-blind, placebo-controlled trial, we randomly assigned 1199 men with primary or hypogonadism-associated osteoporosis who were 50 to 85 years of age to receive an intravenous infusion of zoledronic acid (5 mg) or placebo at baseline and at 12 months. Participants received daily calcium and vitamin D supplementation. The primary end point was the proportion of participants with one or more new morphometric vertebral fractures over a period of 24 months. RESULTS The rate of any new morphometric vertebral fracture was 1.6% in the zoledronic acid group and 4.9% in the placebo group over the 24-month period, representing a 67% risk reduction with zoledronic acid (relative risk, 0.33; 95% confidence interval, 0.16 to 0.70; P=0.002). As compared with men who received placebo, men who received zoledronic acid had fewer moderate-to-severe vertebral fractures (P=0.03) and less height loss (P=0.002). Fewer participants who received zoledronic acid had clinical vertebral or nonvertebral fractures, although this difference did not reach significance because of the small number of fractures. Bone mineral density was higher and bone-turnover markers were lower in the men who received zoledronic acid (P<0.05 for both comparisons). Results were similar in men with low serum levels of total testosterone. The zoledronic acid and placebo groups did not differ significantly with respect to the incidence of death (2.6% and 2.9%, respectively) or serious adverse events (25.3% and 25.2%). CONCLUSIONS Zoledronic acid treatment was associated with a significantly reduced risk of vertebral fracture among men with osteoporosis.

Abstract
This study summarizes the treatment effect of zoledronic acid infusion on lumbar spine bone mineral density in different subgroups with glucocorticoid-induced osteoporosis. Zoledronic acid is significantly more effective than risedronate in increasing lumbar spine (LS) bone mineral density (BMD) in both prevention and treatment of glucocorticoid-induced osteoporosis. Introduction In patients on glucocorticoids, a single zoledronic acid infusion significantly increased BMD versus daily oral risedronate. We assessed treatment effect on LS BMD in different patient subgroups at month 12 that contributed to the risk of osteoporosis in addition to glucocorticoids. Methods Patients randomized to a single IV infusion of zoledronic acid 5 mg or risedronate (5 mg/day) and stratified based on glucocorticoids duration [treatment (>3 months) and prevention (≤ 3 months) subpopulations]were subgrouped by age; gender; menopausal status in women; dose and duration of prednisone during the trial; and baseline serum 25-OH vitamin D, LS BMD T-score, creatinine clearance, and concomitant medication use. Results At month 12, zoledronic acid significantly increased LS BMD versus risedronate in patients ≤ 74 years (P<0.05) in the treatment and 65-74 years (P = 0.0008) in the prevention subpopulation. At month 12, zoledronic acid significantly increased LS BMD versus risedronate in both subpopulations irrespective of gender (all P<0.05), cumulative prednisone dose (all P<0.01), and postmenopausal status (all P<0.05). In premenopausal women, in both subpopulations, zoledronic acid significantly increased total hip BMD (all P<0.05) versus risedronate at month 12 but not LS BMD. Osteoporotic patients in the prevention (P=0.0189) and osteopenic patients in the treatment subpopulation (P=0.0305) showed significant LS BMD increases with zoledronic acid versus risedronate at month 12. Conclusions This post hoc analysis suggests that zoledronic acid is significantly more effective than risedronate in increasing LS BMD in prevention and treatment of glucocorticoid-induced osteoporosis across a wide range of patients.

Abstract
Zoledronic acid 5 mg (ZOL) annually for 3 years reduces fracture risk in postmenopausal women with osteoporosis. To investigate long-term effects of ZOL on bone mineral density (BMD) and fracture risk, the Health Outcomes and Reduced Incidence with Zoledronic acid Once Yearly-Pivotal Fracture Trial (HORIZON-PFT) was extended to 6 years. In this international, multicenter, double-blind, placebo-controlled extension trial, 1233 postmenopausal women who received ZOL for 3 years in the core study were randomized to 3 additional years of ZOL (Z6, n = 616) or placebo (Z3P3, n = 617). The primary endpoint was femoral neck (FN) BMD percentage change from year 3 to 6 in the intent-to-treat (ITT) population. Secondary endpoints included other BMD sites, fractures, biochemical bone turnover markers, and safety. In years 3 to 6, FN-BMD remained constant in Z6 and dropped slightly in Z3P3 (between-treatment difference = 1.04%; 95% confidence interval 0.4 to 1.7; p = 0.0009) but remained above pretreatment levels. Other BMD sites showed similar differences. Biochemical markers remained constant in Z6 but rose slightly in Z3P3, remaining well below pretreatment levels in both. New morphometric vertebral fractures were lower in the Z6 (n = 14) versus Z3P3 (n = 30) group (odds ratio = 0.51; p = 0.035), whereas other fractures were not different. Significantly more Z6 patients had a transient increase in serum creatinine >0.5 mg/dL (0.65% versus 2.94% in Z3P3). Nonsignificant increases in Z6 of atrial fibrillation serious adverse events (2.0% versus 1.1% in Z3P3; p = 0.26) and stroke (3.1% versus 1.5% in Z3P3; p = 0.06) were seen. Postdose symptoms were similar in both groups. Reports of hypertension were significantly lower in Z6 versus Z3P3 (7.8% versus 15.1%, p < 0.001). Small differences in bone density and markers in those who continued versus those who stopped treatment suggest residual effects, and therefore, after 3 years of annual ZOL, many patients may discontinue therapy up to 3 years. However, vertebral fracture reductions suggest that those at high fracture risk, particularly vertebral fracture, may benefit by continued treatment.

Abstract
BACKGROUND We studied 265 men (mean age 56.4 years; range 18-83 years), among patients enrolled in two arms of a double-blind, 1-year study comparing the effects of zoledronic acid (ZOL) with risedronate (RIS) in patients either commencing (prednisolone 7.5 mg/day or equivalent) (prevention arm, n=88) or continuing glucocorticoid therapy (treatment arm, n=177). METHODS Patients received either a single ZOL 5 mg infusion or RIS 5 mg oral daily at randomization, along with calcium (1000 mg) and vitamin D (400-1200 IU). Primary endpoint: difference in percentage change from baseline in bone mineral density (BMD) at the lumbar spine (LS) at 12 months. Secondary endpoints: percentage changes in BMD at total hip (TH) and femoral neck (FN), relative changes in bone turnover markers (β-CTx and P1NP), and overall safety. FINDINGS In the treatment subpopulation, ZOL increased LS BMD by 4.7% vs. 3.3% for RIS and at TH the percentage changes were 1.8% vs. 0.2%, respectively. In the prevention subpopulation, bone loss was prevented by both treatments. At LS the percentage changes were 2.5% vs. -0.2% for ZOL vs. RIS and at TH the percentage changes were 1.1% vs. -0.4%, respectively. ZOL significantly increased lumbar spine BMD more than RIS at Month 12 in both the prevention population (p=0.0024) and the treatment subpopulation (p=0.0232) in men. In the treatment subpopulation, ZOL demonstrated a significantly greater reduction in serum β-CTx and P1NP relative to RIS at all time-points. In the prevention subpopulation, ZOL significantly reduced β-CTx at all time-points, and P1NP at Month 3 (p=0.0297) only. Both treatments were well tolerated in men, albeit with a higher incidence of influenza-like illness and pyrexia events post-infusion with ZOL. INTERPRETATION Once-yearly ZOL preserves or increases BMD within 1 year to a greater extent than daily RIS in men receiving glucocorticoid therapy.

Abstract
UNLABELLED We examined prevalent and recent vertebral fractures in 1 year as predictors of new vertebral fractures over subsequent 2 years using data from RCT placebo patients. We found that prevalent and recent vertebral fractures strongly and independently predicted subsequent vertebral fractures including those which were severe. INTRODUCTION While several studies have shown that prevalent vertebral fractures (pVFx) increase the risk of new vertebral fractures (VFx), the impact of recent vertebral fractures on future fractures is less studied. METHODS Data from the placebo arm of the HORIZON Pivotal Fracture Trial, an international trial of zoledronic acid in postmenopausal, osteoporotic women between 65 and 85 years, were used. We included the subset of 2677 women with annual spinal radiographs to study the impact of vertebral fractures in year 1 (Y1 VF) on those occurring in years 2 and 3 using morphometric and semiquantitative (SQ) criteria. In addition, a subset of severe VFx was defined using SQ criteria. Logistic regression examined the impact of pVFx and Y1 VF on all incident VFx and on severe incident VFx. RESULTS Two hundred fourty-five (9.1%) women sustained a new VFx in years 2-3. VFx risk in years 2-3 was 3.9% in those without pVFx or VFy1 and 29.8% in those with both risk factors. Both pVF and VFy1 remained independent predictors for future VF when they were both entered into a logistic regression model (odds ratio (OR) = 3.3; 95% confidence interval (CI), 2.3-4.7; OR = 3.7, 95% CI, 2.3, 5.8, respectively). ORs were similar after adjustment. Of the total number of women, 4.1% had severe VFx. PVFx and Y1 VF were also significant predictors of severe VFx; however, Y1 VF appeared more strongly predictive of severe VFx. CONCLUSIONS Prevalent and incident vertebral fractures are highly predictive of subsequent new and severe vertebral fractures. Women with both of these risk factors are likely to benefit from anti-osteoporosis treatment.

Abstract
Our purpose was to characterize the risks of osteoporosis-related subtrochanteric fractures in bisphosphonate-naive individuals. Baseline characteristics of patients enrolled in the HORIZON-Recurrent Fracture Trial with a study-qualifying hip fracture were examined, comparing those who sustained incident subtrochanteric fractures with those sustaining other hip fractures. Subjects were bisphosphonate-naive or had a bisphosphonate washout period of 6-24 months and subsequently received an annual infusion of zoledronic acid 5 mg or placebo after low-trauma hip-fracture repair. In total, 2,127 men and women were included. Of the qualifying hip fractures, 5.2% were subtrochanteric, 54.8% femoral neck, 33.0% intertrochanteric, and 7.1% other (generally complex fractures of mixed type). Significant baseline (pre-hip fracture) differences were seen between index hip-fracture types, with the percentage of patients with extreme mobility problems being twofold higher in patients with index subtrochanteric fracture (9.9%) compared to other patients. The distribution of hip-fracture types was similar between the treatment groups at baseline. No patients with index subtrochanteric fractures and six patients with other qualifying hip fractures reported prior bisphosphonate use. Only one further subtrochanteric fracture occurred in each treatment group over an average 2-year patient follow-up. Subtrochanteric fractures are not uncommon in bisphosphonate-naive patients. Extreme difficulties with mobility may be a unique risk factor predisposing to development of incident subtrochanteric fractures rather than other types of hip fracture. In patients with recent hip fracture who received zoledronic acid therapy, the incidence of new subtrochanteric fractures was too small to draw any meaningful conclusions.

Abstract
OBJECTIVES To assess the efficacy of once-yearly zoledronic acid (ZOL) 5 mg in increasing bone mineral density (BMD) in men with a recent hip fracture participating in the Health Outcomes and Reduced Incidence with Zoledronic Acid Once- Yearly Recurrent Fracture Trial and to compare the efficacy with that in women from the same study. DESIGN Randomized, placebo-controlled, double-blind trial. SETTING International multicenter. PARTICIPANTS Five hundred and eight men and 1,619 women within 90 days of surgical repair of low-trauma hip fracture in the same study (for comparison). INTERVENTION Once-yearly intravenous (IV) ZOL 5 mg (n = 248) or placebo (n = 260), loading dose of vitamin D, daily calcium, and vitamin D supplements. MEASUREMENT Changes in BMD. RESULTS Percentage change from baseline in total hip BMD at Months 12 and 24 was significantly higher with ZOL than with placebo (between-group difference, 2.0%, P = .003, and 3.8%, P = .002, respectively). Percentage change from baseline in femoral neck BMD at Month 24 was significantly higher with ZOL than with placebo (3.8%, P = .003). The BMD benefit was comparable with that observed in women in this study. New clinical fractures occurred in 36 (7.1%) participants (ZOL, n = 16; placebo, n = 20; P = .64). The ZOL safety profile was comparable with that of placebo, with no significant differences in cardiovascular or long-term renal function and a trend toward lower mortality in ZOL-treated men. CONCLUSION Once-yearly IV ZOL 5 mg increases bone mass at the hip and femoral neck in men within 90 days of repair of a low-trauma hip fracture. Increases were of a similar magnitude to those observed in women in the same study.

At month 24 and end of the study visit, ZOL significantly improved patients' overall health state compared to placebo as assessed by the EQ-5D VAS. INTRODUCTION To evaluate the benefits of zoledronic acid (ZOL) versus placebo on health-related quality of life (HRQoL) among patients from The Health Outcomes and Reduced Incidence With Zoledronic Acid Once Yearly Recurrent Fracture Trial (HORIZON-RFT). METHODS In this randomized, double-blind, placebo-controlled trial, 2,127 patients were randomized to receive annual infusion of ZOL 5 mg (n = 1,065) or placebo (n = 1,062) within 90 days after surgical repair of low-trauma hip fracture. HRQoL was measured using EQ-5D Visual Analogue Scale (VAS) and utility scores (EuroQol instrument) at months 6, 12, 24, 36, and end of the study visit. Analysis of covariance model included baseline EQ-5D value, region, and treatment as explanatory variables. RESULTS At baseline, patients (mean age 75 years; 24% men and 76% women) were well matched between treatment groups with mean EQ-5D VAS of 65.82 in ZOL and 65.70 in placebo group. At the end of the study, mean change from baseline in EQ-5D VAS was greater for ZOL vs. placebo in all patients (7.67 ± 0.56 vs. 5.42 ± 0.56), and in subgroups of patients experiencing clinical vertebral fractures (8.86 ± 4.91 vs. -1.69 ± 3.42), non-vertebral fractures (5.03 ± 2.48 vs. -1.07 ± 2.16), and clinical fractures (5.19 ± 2.25 vs. -0.72 ± 1.82) with treatment difference significantly in favor of ZOL. EQ-5D utility scores were comparable for ZOL and placebo groups, but more patients on placebo consistently had extreme difficulty in mobility (1.74% for ZOL vs. 2.13% for placebo; p = 0.6238), self-care (4.92% vs. 6.69%; p = 0.1013), and usual activities (10.28% vs. 12.91%; p = 0.0775). CONCLUSION ZOL significantly improves HRQoL in patients with low-trauma hip fracture.

Abstract
Two trials have shown that a single 5-mg infusion of zoledronic acid achieves much higher response rates in Paget disease of bone than risedronate. The duration of this effect is unknown. We have conducted an open follow-up of responders from the two trials (152 originally treated with zoledronic acid, 115 with risedronate) out to 6.5 years without further intervention. Endpoints were times to relapse (ie, return of serum total alkaline phosphatase activity to within 20% of the pretreatment value) or loss of response (response = normalization of alkaline phosphatase or 75% or greater reduction in its excess). Bone turnover markers were lower in the zoledronic acid group throughout follow-up, with mean alkaline phosphatase (ALP) remaining within the reference range in these patients, whereas the mean in the risedronate group was above normal from 1 year. Relapse rates were substantially greater in the risedronate group (23 of 115, 20%) than in those treated with zoledronic acid (1 of 152, 0.7%, p < .001), and loss of response occurred in 19 (12.5%) zoledronic acid patients compared with 71 (62%) risedronate patients (p < .0001). Risk ratios for relapse and loss of response in zoledronic acid patients were 0.02 [95% confidence interval (CI) 0.00-0.18] and 0.12 (95% CI 0.07-0.19), respectively. Changes from baseline in quality of life, assessed using SF-36 scores, were more positive in the zoledronic acid group across the follow-up period (p = .01). Bone markers at 6 months were predictive of response duration. These data demonstrate an unprecedented duration of remission of Paget disease following treatment with zoledronic acid, accompanied by an improved quality of life.

Abstract
UNLABELLED Patients in the Health Outcomes and Reduced Incidence with Zoledronic Acid Once Yearly (HORIZON) Recurrent Fracture Trial were assessed for evidence of delayed hip fracture healing. No association was observed between zoledronic acid (ZOL) and delayed healing. We conclude that ZOL has no clinically evident effect on fracture healing, even when the drug is infused in the immediate postoperative period. INTRODUCTION Intravenous zoledronic acid 5 mg (ZOL) given after a hip fracture reduces secondary fracture rates and mortality. It has been postulated that bisphosphonates may affect healing if given soon after a fracture. We sought to determine whether the timing of ZOL infusion affected the risk of delayed hip fracture healing. METHODS In the HORIZON Recurrent Fracture Trial, patients were randomized within 90 days of a low-trauma hip fracture to receive either once-yearly ZOL (n = 1,065) or placebo (n = 1,062). Clinical symptoms of delayed hip fracture healing were sought at randomization, 6 months and 12 months after fracture; if present, a central adjudication committee blinded to treatment assignment reviewed radiographs and clinical records. Median follow-up was 1.9 years. RESULTS The overall incidence of delayed healing was 3.2% (ZOL) and 2.7% (placebo; odds ratio [OR], 1.17; 95% confidence interval [CI], 0.72-1.90; p = 0.61). Logistic regression models revealed no association between ZOL and delayed healing even after adjusting for other risk factors (OR, 1.21; 95% CI, 0.74-1.99; p = 0.44). There was no interaction by timing of infusion, and nonunion rates were similar even when ZOL was given within 2 weeks of hip fracture repair. NSAID use was significantly associated with delayed fracture healing (OR, 2.55; 95% CI, 1.49-4.39; p < 0.001). CONCLUSIONS ZOL has no clinically evident effect on fracture healing, even when the drug is infused in the immediate postoperative period.

Abstract
Clinical data suggest concomitant therapy with bisphosphonates and parathyroid hormone (PTH) may blunt the anabolic effect of PTH; rodent models suggest that infrequently administered bisphosphonates may interact differently. To evaluate the effects of combination therapy with an intravenous infusion of zoledronic acid 5 mg and daily subcutaneous recombinant human (rh)PTH(1-34) (teriparatide) 20 µg versus either agent alone on bone mineral density (BMD) and bone turnover markers, we conducted a 1-year multicenter, multinational, randomized, partial double-blinded, controlled trial. 412 postmenopausal women with osteoporosis (mean age 65 ± 9 years) were randomized to a single infusion of zoledronic acid 5 mg plus daily subcutaneous teriparatide 20 µg (n = 137), zoledronic acid alone (n = 137), or teriparatide alone (n = 138). The primary endpoint was percentage increase in lumbar spine BMD (assessed by dual-energy X-ray absorptiometry [DXA]) at 52 weeks versus baseline. Secondary endpoints included change in BMD at the spine at earlier time points and at the total hip, trochanter, and femoral neck at all time points. At week 52, lumbar spine BMD had increased 7.5%, 7.0%, and 4.4% in the combination, teriparatide, and zoledronic acid groups, respectively (p < .001 for combination and teriparatide versus zoledronic acid). In the combination group, spine BMD increased more rapidly than with either agent alone (p < .001 versus both teriparatide and zoledronic acid at 13 and 26 weeks). Combination therapy increased total-hip BMD more than teriparatide alone at all times (all p < .01) and more than zoledronic acid at 13 weeks (p < .05), with final 52-week increments of 2.3%, 1.1%, and 2.2% in the combination, teriparatide, and zoledronic acid groups, respectively. With combination therapy, bone formation (assessed by serum N-terminal propeptide of type I collagen [PINP]) increased from 0 to 4 weeks, declined minimally from 4 to 8 weeks, and then rose throughout the trial, with levels above baseline from 6 to 12 months. Bone resorption (assessed by serum β-C-telopeptide of type I collagen [β-CTX]) was markedly reduced with combination therapy from 0 to 8 weeks (a reduction of similar magnitude to that seen with zoledronic acid alone), followed by a gradual increase after week 8, with levels remaining above baseline for the latter half of the year. Levels for both markers were significantly lower with combination therapy versus teriparatide alone (p < .002). Limitations of the study included its short duration, lack of endpoints beyond DXA-based BMD (e.g., quantitative computed tomography and finite-element modeling for bone strength), lack of teriparatide placebo, and insufficient power for fracture outcomes. We conclude that while teriparatide increases spine BMD more than zoledronic acid and zoledronic acid increases hip BMD more than teriparatide, combination therapy provides the largest, most rapid increments when both spine and hip sites are considered.

Abstract
Zoledronic acid (ZOL) has shown beneficial effects on bone turnover and bone mineral density (BMD) in postmenopausal osteoporosis. This study compared the efficacy and safety of a once-yearly i.v. infusion of ZOL with weekly oral alendronate (ALN) in men with osteoporosis. In this multicenter, double-blind, active-controlled, parallel-group study, participants (n = 302) were randomized to receive either once-yearly ZOL 5 mg i.v. or weekly oral ALN 70 mg for 24 months. Changes in BMD and bone marker levels were assessed. ZOL increased BMD at the lumbar spine, total hip, femoral neck, and trochanter and was not inferior to ALN at 24 months [least squares mean estimates of the percentage increases in lumbar spine BMD of 6.1% and 6.2%; difference approximately 0.13; 95% confidence interval (CI) 1.12-0.85 in the ZOL and ALN groups, respectively]. At month 12, the median change from baseline of markers for bone resorption [serum β-C-terminal telopeptide of type I collagen (β-CTx) and urine N-terminal telopeptide of type I collagen (NTx)] and formation [serum N-terminal propeptide of type I collagen (P1NP) and serum bone-specific alkaline phosphatase (BSAP)] were comparable between ZOL and ALN groups. Most men preferred i.v. ZOL over oral ALN. The incidence of adverse events and serious adverse events was similar in the treatment groups. It is concluded that a once-yearly i.v. infusion of ZOL 5 mg increased bone density and decreased bone turnover markers similarly to once-weekly oral ALN 70 mg in men with low bone density.

Abstract
BACKGROUND A number of recent case reports and series have identified a subgroup of atypical fractures of the femoral shaft associated with bisphosphonate use. A population-based study did not support this association. Such a relationship has not been examined in randomized trials. METHODS We performed secondary analyses using the results of three large, randomized bisphosphonate trials: the Fracture Intervention Trial (FIT), the FIT Long-Term Extension (FLEX) trial, and the Health Outcomes and Reduced Incidence with Zoledronic Acid Once Yearly (HORIZON) Pivotal Fracture Trial (PFT). We reviewed fracture records and radiographs (when available) from all hip and femur fractures to identify those below the lesser trochanter and above the distal metaphyseal flare (subtrochanteric and diaphyseal femur fractures) and to assess atypical features. We calculated the relative hazards for subtrochanteric and diaphyseal fractures for each study. RESULTS We reviewed 284 records for hip or femur fractures among 14,195 women in these trials. A total of 12 fractures in 10 patients were classified as occurring in the subtrochanteric or diaphyseal femur, a combined rate of 2.3 per 10,000 patient-years. As compared with placebo, the relative hazard was 1.03 (95% confidence interval [CI], 0.06 to 16.46) for alendronate use in the FIT trial, 1.50 (95% CI, 0.25 to 9.00) for zoledronic acid use in the HORIZON-PFT trial, and 1.33 (95% CI, 0.12 to 14.67) for continued alendronate use in the FLEX trial. Although increases in risk were not significant, confidence intervals were wide. CONCLUSIONS The occurrence of fracture of the subtrochanteric or diaphyseal femur was very rare, even among women who had been treated with bisphosphonates for as long as 10 years. There was no significant increase in risk associated with bisphosphonate use, but the study was underpowered for definitive conclusions.
