Efficacy Of Baricitinib in Patients With Moderate-To-Severe Rheumatoid Arthritis Up to 6.5 Years Of Treatment: Results Of A Long-Term Study.

OBJECTIVES: To evaluate the long-term efficacy of once-daily baricitinib 4 mg or 2 mg in patients with active rheumatoid arthritis who had inadequate response (IR) to MTX, csDMARDs, or bDMARDs. METHODS: Data from three completed phase III studies, RA-BEAM (MTX-IR), RA-BUILD (csDMARD-IR), and RA-BEACON (bDMARD-IR), and one completed long-term extension study (RA-BEYOND) were analyzed up to 6.5 years (340 weeks [RA-BEAM] and 336 weeks [RA-BUILD and RA-BEACON]). Low disease activity (LDA) (Simplified Disease Activity Index [SDAI] ≤11), clinical remission (SDAI ≤3.3), and physical function (Health Assessment Questionnaire Disability Index [HAQ-DI] ≤0.5) were the main outcomes assessed. Completer and non-responder imputation (NRI) analyses were conducted on each population. RESULTS: At week 340 or 336, LDA was achieved in 37%/83% of MTX-IR, 35%/83% of csDMARD-IR, and 23%/73% of bDMARD-IR patients treated with baricitinib 4 mg, assessed by NRI/completer analyses, respectively. Remission was achieved in 20%/40% of MTX-IR, 13%/32% of csDMARD-IR, and 9%/30% of bDMARD-IR patients treated with baricitinib 4 mg, assessed by NRI/completer analyses, respectively. HAQ-DI ≤0.5 was reached in 31%/51% of MTX-IR, 25%/46% of csDMARD-IR, and 24%/38% of bDMARD-IR patients treated with baricitinib 4 mg, assessed by NRI/completer analyses, respectively. CONCLUSION: Treatment with baricitinib 4 mg or 2 mg demonstrated efficacy up to 6.5 years with maintained LDA/remission results across SDAI, CDAI and DAS28-hsCRP consistent with previously reported data, and was well tolerated.

Radiographic Progression of Structural Joint Damage Over 5 Years of Baricitinib Treatment in Patients With Rheumatoid Arthritis: Results From RA-BEYOND.

OBJECTIVE: To evaluate the effect of baricitinib on inhibiting radiographic progression of structural joint damage over 5 years in patients with active rheumatoid arthritis (RA). METHODS: Patients completed 1 of 3 phase III baricitinib trials (ClinicalTrials.gov: NCT01711359, NCT01710358, or NCT01721057) and entered the long-term extension RA-BEYOND (NCT01885078), in which patients received once-daily 4 mg or 2 mg baricitinib. Across these trials, patients initially receiving methotrexate (MTX) or adalimumab (ADA) switched to baricitinib 4 mg at Week 52. Patients initially receiving placebo (PBO) switched to baricitinib 4 mg at Week 24. Radiographs were scored at baseline and Years 2, 3, 4, and 5. Change from baseline in van der Heijde modified total Sharp score (ΔmTSS) was computed. RESULTS: Overall, 2125 of 2573 (82.6%) randomized patients entered RA-BEYOND; 1837 of 2125 (86.4%) entered this analysis. From Years 3 to 5, higher proportions of disease-modifying antirheumatic drug (DMARD)-naïve patients on initial baricitinib (monotherapy or with MTX) had no progression vs initial MTX (ΔmTSS ≤ 0 at Year 5: 59.6% baricitinib 4 mg; 66.2% baricitinib 4 mg + MTX; 40.7% MTX). Higher proportions of patients with inadequate response (IR) to MTX on initial baricitinib or ADA vs PBO had no progression (ΔmTSS ≤ 0 at Year 5: 54.8% baricitinib 4 mg; 55.0% ADA; 50.3% PBO). Higher proportions of patients with conventional synthetic DMARD-IR on initial baricitinib 4 mg had less progression vs initial PBO or baricitinib 2 mg (ΔmTSS ≤ 0 at Year 5: 66.7% baricitinib 4 mg; 58.2% baricitinib 2 mg; 60.0% PBO). CONCLUSION: Oral baricitinib maintained lower levels of radiographic progression than initial conventional synthetic DMARD or PBO through 5 years in patients with active RA.

Pain Reduction in Rheumatoid Arthritis Patients Who Use Opioids: A Post Hoc Analysis of Phase 3 Trials of Baricitinib.

OBJECTIVE: Pain reduction with baricitinib was assessed in patients with rheumatoid arthritis (RA) who either used opioids or did not use opioids during three randomized, double-blind phase 3 trials. METHODS: Analysis populations were as follows: i) baricitinib 4 mg once daily versus placebo groups integrated from RA-BEAM (NCT01710358) for patients with inadequate response (IR) to methotrexate, RA-BUILD (NCT01721057) with IR to conventional disease-modifying antirheumatic drugs, and RA-BEACON (NCT01721044) with IR to at least one tumor necrosis factor inhibitors; ii) baricitinib 2 mg versus placebo from RA-BUILD and RA-BEACON; and iii) adalimumab 40 mg every other week versus placebo from RA-BEAM. Pain was measured by the Patient Assessment of Pain Visual Analog Scale. Analysis of covariance modeling assessed differences in pain reduction between treatments at each time point through Week 24, with an interaction term to test heterogeneous treatment effects across opioid users and nonusers. RESULTS: Baricitinib 4 mg had greater pain reduction versus placebo in opioid users and nonusers (P < 0.05) at all time points starting from Week 1; the pain reduction was similar between opioid users and nonusers. Baricitinib 2 mg had greater pain reduction versus placebo in opioid users and nonusers starting at Week 4. A significant difference in pain reduction was not observed for adalimumab versus placebo in the opioid users but was observed in nonusers at all time points. CONCLUSION: Pain reduction was observed and was similar between opioid users and nonusers with baricitinib 2 mg and 4 mg but not adalimumab in this post hoc analysis.

Fracture risk in adult patients treated with growth hormone replacement therapy for growth hormone deficiency: a prospective observational cohort study.

BACKGROUND: To our knowledge, no controlled studies of the effects of long-term growth hormone replacement on fracture risk in adult patients with growth hormone deficiency exist. We assessed the effect of growth hormone treatment on fracture risk in patients with growth hormone deficiency from the international Hypopituitary Control and Complications Study (HypoCCS) surveillance database. METHODS: In this prospective cohort study, patients with growth hormone deficiency were analysed from the HypoCCS database of adults with hypopituitarism from the USA, Canada, Japan, and 14 European countries. Patients were eligible if they were aged 18 years or older and had an established diagnosis of growth hormone deficiency, either alone or with multiple pituitary hormone deficiencies, as identified by clinical history and biochemical testing. Patients were assessed over a mean follow-up period of 4·6 years (SD 3·8). The effect of growth hormone treatment on fracture risk was assessed by Cox proportional hazard modelling with adjustment for several confounders. FINDINGS: Between Jan 3, 1996, and Dec 15, 2012, we enrolled 10,673 patients to this study. Of the enrolled patients, 1032 patients were excluded from assessment because of incomplete data, leaving 9641 in the analysis cohort. Of these patients, 8374 of received growth hormone and 1267 did not. Annual fracture incidence rate was lower in patients who received growth hormone than in those who did not (fracture incidence rate 1·19% vs 1·91%, hazard ratio [HR] 0·69, 95% CI 0·54-0·88). However, no difference in fracture risk was observed between patients who did and did not receive growth hormone treatment in the subgroup of patients with pre-existing osteoporosis (n=826; 0·97, 0·48-1·95). INTERPRETATION: Our results suggest that growth hormone replacement therapy could be protective against fracture for adult patients with growth hormone deficiency without previously reported osteoporosis. Starting growth hormone therapy before the onset of osteoporosis might be optimum for bone health of adult patients with growth hormone deficiency. FUNDING: Eli Lilly and Co.

Ten-year change in quality of life in adults on growth hormone replacement for growth hormone deficiency: an analysis of the hypopituitary control and complications study.

CONTEXT: Previous studies showed improvement in impaired quality of life (QoL) in adult patients with growth hormone (GH) deficiency (GHD) who were treated with GH; improvement was sustained over a few years after GH therapy. OBJECTIVE: To evaluate the QoL over 10 years. DESIGN: This was a prospective observational study. SETTING: The study was conducted in clinical practice. PATIENTS: 1436 adult patients with adult-onset (AO) GHD (mean age [standard deviation (SD)]: 49.0 [12.2] years; 49% female) and 96 with childhood-onset (CO) GHD (31.3 [10.0] years; 60% female) (total N = 1532). INTERVENTION: GH therapy. MAIN OUTCOME MEASURES: QoL was measured by Questions on Life Satisfaction-Hypopituitarism (QLS-H) in countries where validated questionnaires and normative data for calculation of Z-scores were available. Change in QoL was tested by Student's t test and predicted by mixed-model repeated measures (MMRM) analysis. RESULTS: At study entry, patients had diminished QoL Z-scores (mean [SD] AO, -1.55 [1.69]; CO -0.98 [1.32]). The largest QoL improvements were in the first year: mean (SD) increase 0.77 (1.37) for AO (P < .001) and 0.50 (1.37) for CO (P < .001). The initial improvement from study entry remained statistically significant throughout 10 years for AO and in years 1 to 4, 6, and 7 for CO (P < .05). MMRM analysis predicted a greater QoL improvement in those who were not depressed, lived in Europe, had poorer Z-scores at entry, had lower body mass index at entry, and had no impaired vision. CONCLUSION: These data suggest that GH replacement provides sustained improvement in QLS-H scores toward normality for up to 10 years.

Adult mortality or morbidity is not increased in childhood-onset growth hormone deficient patients who received pediatric GH treatment: an analysis of the Hypopituitary Control and Complications Study (HypoCCS).

BACKGROUND: The French Safety and Appropriateness of Growth Hormone treatments in Europe (SAGhE) cohort has raised concern of increased mortality risk during follow-up into adulthood in certain patients who had received growth hormone (GH) treatment during childhood. The Hypopituitary Control and Complications Study monitored mortality and morbidity of adult GH-deficient patients including those with childhood-onset GH deficiency (COGHD) who received GH treatment as children. PURPOSE: Evaluate risk of mortality, cancer, myocardial infarction (MI) and stroke in a prospective observational study. METHODS: COGHD patients [n = 1,204, including 389 diagnosed with idiopathic COGHD (ICOGHD)] had received pediatric GH treatment. Standardized mortality ratios (SMRs), and cancer standardized incidence ratios (SIRs) in patients without a prior cancer were estimated relative to reference populations. Crude incidence rates were estimated for MI and stroke. RESULTS: No increased mortality or cancer incidence was observed, as compared with reference populations, during a follow-up of 3.7 ± 3.3 years (mean ± SD). The overall SMR for COGHD was 1.14 [95 % confidence interval (CI) 0.55-2.10], and for ICOGHD, 0.33 (0.01-1.84). The overall cancer SIR for COGHD was 0.27 (0.01-1.50), and for ICOGHD, 0.00 (0.00-2.45). No incident case of MI was reported. The crude stroke incidence rate [181.3 per 100,000 person-years] in COGHD patients was consistent with the rates reported in reference populations. No incident case of stroke was identified in ICOGHD patients who are presumed to have no increased stroke risk factors. CONCLUSIONS: The results indicate no increased risk of mortality or incidence of cancer, stroke, or MI in adult GH-deficient patients who had previously received pediatric GH treatment.

Prevalence and incidence of diabetes mellitus in adult patients on growth hormone replacement for growth hormone deficiency: a surveillance database analysis.

CONTEXT: GH replacement in adult GH-deficient patients may cause insulin resistance, raising concerns of potential increased risk of developing diabetes mellitus (DM). OBJECTIVE: Our objective was to assess DM prevalence and incidence in the international Hypopituitary Control and Complications Study (HypoCCS) surveillance database. DESIGN AND PARTICIPANTS: GH-treated patients enrolled into HypoCCS (2922 U.S. and 3709 European patients) were assessed for DM, defined as recorded on the clinical report form, reported as adverse events, fasting glucose at least 7 mmol/liter recorded at least twice, or insulin treatment reported. RESULTS: DM prevalence was 8.2% [95% confidence interval (CI) = 7.6-8.9] overall, 11.3% in the United States and 5.7% in Europe. Incidence (n/1000 patient-years) was 9.7 (95% CI = 8.4-10.9) overall, 14.1 (11.5-16.7) in the United States, and 7.0 (5.6-8.3) in Europe. Overall incidence was 2.1 (0.9-3.3) for patients with body mass index (BMI) below 25 kg/m(2) increasing to 16.4 (13.7-19.1) for BMI over 30 kg/m(2). Obesity (BMI > 30 kg/m(2)) prevalence was higher in the United States than Europe and higher in U.S. patients than a U.S. reference population. After age, gender, and BMI adjustment, U.S. HypoCCS DM incidence was 10.6 (8.1-13.0), compared with 7.1 (6.0-8.1) in the National Health Interview Survey. In Europe, incidence for French and German patients was comparable to reference populations; for Sweden, the point estimate was higher than the reference population, but 95% CI overlapped. GH dose was not correlated with DM incidence. CONCLUSIONS: The present analysis showed no evidence for increased DM incidence in GH-treated adult hypopituitary patients. However, those more prone to develop DM exhibited a higher than normal prevalence of obesity.

Prevalence of metabolic syndrome in adult hypopituitary growth hormone (GH)-deficient patients before and after GH replacement.

CONTEXT AND OBJECTIVE: Metabolic and body compositional consequences of GH deficiency (GHD) in adults are associated with a phenotype similar to the metabolic syndrome (MetS). PATIENTS: We assessed MetS prevalence in adult GHD patients (n = 2531) enrolled in the Hypopituitary Control and Complications Study. Prevalence was assessed at baseline and after 3 yr of GH replacement in a subset of 346 adult-onset patients. RESULTS: Baseline MetS crude prevalence was 42.3%; age-adjusted prevalence in the United States and Europe was 51.8 and 28.6% (P < 0.001), respectively. In the United States, age-adjusted prevalence was significantly higher (P < 0.001) than in a general population survey. Increased MetS risk at baseline was observed for age 40 yr or older (adjusted relative risk 1.34, 95% confidence interval 1.17-1.53, P < 0.001), females (1.15, 1.05-1.25, P = 0.002), and adult onset (1.77, 1.44-2.18, P < 0.001). In GH-treated adult-onset patients, MetS prevalence was not changed after 3 yr (42.5-45.7%, P = 0.172), but significant changes were seen for waist circumference (62.1-56.9%, P = 0.008), fasting glucose (26.0-32.4%, P < 0.001), and blood pressure (59.8-69.7%, P < 0.001). Significantly increased risk of MetS at yr 3 was associated with baseline MetS (adjusted relative risk 4.09, 95% confidence interval 3.02-5.53, P < 0.001) and body mass index 30 kg/m(2) or greater (1.53, 1.17-1.99, P = 0.002) and increased risk (with a P value < 0.1) for GH dose 600 microg/d or greater (1.18, 95% confidence interval 0.98-1.44, P = 0.088). CONCLUSION: MetS prevalence in GHD patients was higher than in the general population in the United States and higher in the United States than Europe. Prevalence was unaffected by GH replacement, but baseline MetS status and obesity were strong predictors of MetS after GH treatment.

Metabolic, cardiovascular, and cerebrovascular outcomes in growth hormone-deficient subjects with previous cushing's disease or non-functioning pituitary adenoma.

CONTEXT: Previous exposure to hypercortisolism due to Cushing's disease (CD) may adversely affect long-term metabolic and cardiovascular outcomes. In particular, metabolic and cardiovascular outcomes of patients with previous CD who require GH replacement have not been fully established. OBJECTIVE: The aim of the study was to compare the prevalence and incidence of metabolic syndrome (Adult Treatment Panel III criteria), diabetes mellitus, cardiovascular disease, and cerebrovascular disease in GH-treated subjects with previous CD with GH-treated subjects with previous nonfunctioning pituitary adenoma (NFPA). DESIGN: We conducted post hoc analysis of the observational Hypopituitary Control and Complications Study conducted at 362 international centers (1995-2006). SUBJECTS: We studied adult-onset GH-deficient subjects with previous CD (n = 160) or NFPA (n = 879). All subjects received GH replacement therapy and were GH naive at enrollment. Multiple pituitary deficits were prevalent in both groups. MAIN OUTCOME MEASURES: We measured the prevalence and incidence of metabolic syndrome, diabetes mellitus, cardiovascular disease, and cerebrovascular disease at baseline and at 3 yr, standardized for age and sex differences between groups. RESULTS: Compared with subjects with previous NFPA, subjects with previous CD had a significantly greater 3-yr incidence of metabolic syndrome (CD, 23.4%; NFPA, 9.2%; P = 0.01), baseline (CD, 6.3%; NFPA, 2.2%; P < 0.01) and 3-yr (CD, 7.6%; NFPA, 3.9%; P = 0.04) prevalence of cardiovascular disease, and baseline (CD, 6.4%; NFPA, 1.8%; P = 0.03) and 3-yr (CD, 10.2%; NFPA, 2.9%; P = 0.01) prevalence of cerebrovascular disease. CONCLUSIONS: Previous hypercortisolism may predispose GH-treated, GH-deficient subjects with prior CD to an increased risk of metabolic syndrome, cardiovascular disease, and cerebrovascular disease.

Changing patterns of the adult growth hormone deficiency diagnosis documented in a decade-long global surveillance database.

BACKGROUND: GH therapy in adult patients with GH deficiency (GHD) was approved over 10 yr ago, and the indication has subsequently gained broad acceptance. The HypoCCS surveillance database is a suitable means to examine the evolution of diagnostic patterns since 1996. METHODS: Baseline demographics, reported cause of GHD, and diagnostic tests were available from 5893 GH-treated patients. Trends for change over time in diagnosis, GH stimulation test data, and IGF-I measurements were analyzed at 2-yr intervals by linear regression models, with entry year as the predictive variable. RESULTS: Over the decade, there was a decrease in patients enrolled with diagnoses of pituitary adenoma (50.2 to 38.6%; P < 0.001), craniopharyngioma (13.3 to 8.4%; P = 0.005) and pituitary hemorrhage (5.8 to 2.8%; P = 0.001); increases in idiopathic GHD (13.9 to 19.3%; P < 0.001), less common diagnoses (7.4 to 15.8%; P < 0.001), and undefined/unknown diagnoses (1.3 to 8.6%; P < 0.001) were observed. Use of arginine, clonidine, and L-dopa tests declined, whereas use of the GHRH-arginine test increased. Median values for peak GH from all tests except GHRH-arginine and for IGF-I SD scores increased significantly (P < 0.001). Over the decade (1996--2005), idiopathic GHD was reported for 16.7% of patients, and more than half of these had adult onset GHD. In the idiopathic adult onset group, 40.2% had isolated GHD; 18.3 and 4.4% had a stimulation test GH peak of at least 3.0 and 5.0 microg/liter, respectively. CONCLUSIONS: Significant shifts in diagnostic patterns have occurred since approval of the adult GHD indication, with a trend to less severe forms of GHD.

Breast cancer trends in Manitoba: 40 years of follow-up.

This study reports a comprehensive array of breast cancer statistics for Manitoba for a 40-year period. Data from the Manitoba Cancer Registry were combined with the provincial population-based registration file to determine trends in breast cancer incidence, prevalence and mortality rates, as well as survival and the probability of being diagnosed with breast cancer in the next 10 years. The age-standardized incidence rate of breast cancer increased by 0.99/100,000 women per year over the 40 years of follow-up (69.6/100,000 women in 1960, 109.9/100,000 women in 1999). Mortality rates peaked in 1986 (35.7/100,000 women), while the 1999 mortality rate (26.0/100,000 women) was almost comparable to the 1960 rate (22.4/100,000 women). No significant trend in mortality rate was observed over the 40-year period. The 5-year prevalence rate of breast cancer increased by 8.6/100,000 women per year. Between 1960-64 and 1995-99, 5-year survival increased from 0.62 to 0.86. The probability of being diagnosed with breast cancer in the next 10 years increased the most for women 60 years of age. The breast cancer burden in Manitoba is rapidly evolving mainly because of the increasing incidence and the better survival of cases. Key words: breast neoplasms, incidence, prevalence, registries, vital statistics.
