ABSTRACT

OBJECTIVES: Individuals in recovery from opioid use disorder (OUD) are vulnerable to the impacts of the COVID-19 pandemic. Recent findings suggest increased relapse risk and overdose linked to COVID-19-related stressors. We aimed to identify individual-level factors associated with COVID-19-related impacts on recovery. METHODS: This observational study (NCT04577144) enrolled 216 participants who previously partook in long-acting buprenorphine subcutaneous injection clinical trials (2015-2017) for OUD. Participants indicated how COVID-19 affected their recovery from substance use. A machine learning approach Classification and Regression Tree analysis examined the association of 28 variables with the impact of COVID-19 on recovery, including demographics, substance use, and psychosocial factors. Ten-fold cross-validation was used to minimize overfitting. RESULTS: Twenty-six percent of the sample reported that COVID-19 had made recovery somewhat or much harder. Past-month opioid use was higher among those who reported that recovery was harder compared with those who did not (51% vs 24%, respectively; P < 0.001). The final classification tree (overall accuracy, 80%) identified the Beck Depression Inventory (BDI-II) as the strongest independent risk factor associated with reporting COVID-19 impact. Individuals with a BDI-II score ≥10 had 6.45 times greater odds of negative impact (95% confidence interval, 3.29-13.30) relative to those who scored <10. Among individuals with higher BDI-II scores, less progress in managing substance use and treatment of OUD within the past 2 to 3 years were also associated with negative impacts. CONCLUSIONS: These findings underscore the importance of monitoring depressive symptoms and perceived progress in managing substance use among those in recovery from OUD, particularly during large-magnitude crises.

ABSTRACT

BACKGROUND AND AIMS: Limited information exists regarding individual subgroups of recovery from opioid use disorder (OUD) following treatment and how these subgroups may relate to recovery trajectories. We used multi-dimensional criteria to identify OUD recovery subgroups and longitudinal transitions across subgroups. DESIGN, SETTING AND PARTICIPANTS: In a national longitudinal observational study in the United States, individuals who previously participated in a clinical trial for subcutaneous buprenorphine injections for treatment of OUD were enrolled and followed for an average of 4.2 years after participation in the clinical trial. MEASUREMENTS: We identified recovery subgroups based on psychosocial outcomes including depression, opioid withdrawal and pain. We compared opioid use, treatment utilization and quality of life among these subgroups. FINDINGS: Three dimensions of the recovery process were identified: depression, opioid withdrawal and pain. Using these three dimensions, participants were classified into four recovery subgroups: high-functioning (minimal depression, mild withdrawal and no/mild pain), pain/physical health (minimal depression, mild withdrawal and moderate pain), depression (moderate depression, mild withdrawal and mild/moderate pain) and low-functioning (moderate/severe withdrawal, moderate depression and moderate/severe pain). Significant differences among subgroups were observed for DSM-5 criteria (P < 0.001) and remission status (P < 0.001), as well as with opioid use (P < 0.001), treatment utilization (P < 0.001) and quality of life domains (physical health, psychological, environment and social relationships; Ps < 0.001, Cohen's fs ≥ 0.62). Recovery subgroup assignments were dynamic, with individuals transitioning across subgroups during the observational period. Moreover, the initial recovery subgroup assignment was minimally predictive of long-term outcomes. CONCLUSIONS: There appear to be four distinct subgroups among individuals in recovery from OUD. Recovery subgroup assignments are dynamic and predictive of contemporaneous, but not long-term, substance use, substance use treatment utilization or quality of life outcomes.

ABSTRACT

BACKGROUND: Opioid use disorder (OUD) seriously impacts public health in the United States. However, few investigations of long-term outcomes following treatment with medication for OUD exist. Additionally, these studies have prioritized opioid use and treatment utilization outcomes, and a gap in knowledge regarding long-term, multidimensional trajectories of OUD recovery exists. This study investigated a diverse array of outcomes for individuals with OUD at an average of 4.2 years post clinical trial participation. METHODS: Individuals who previously participated in long-acting buprenorphine subcutaneous injection clinical trials (NCT023579011; NCT025100142; NCT02896296) and enrolled in The Remission from Chronic Opioid Use-Studying Environmental and SocioEconomic Factors on Recovery (RECOVER; NCT03604861) Study participated in a follow up assessment (n = 216). Substance use, psychosocial, opioid dependence, and delay discounting outcomes were assessed. Regression analyses were conducted to determine significant associations between psychosocial/opioid dependence variables and both recent opioid use and delay discounting. RESULTS: The majority of participants reported abstinence from opioids since the last RECOVER study assessment (mean 2.26 years; 55%) and in the past 30 days (69%). Participants reported low levels of depression and psychological distress. Positive associations between depression and opioid craving with past 30-day opioid misuse and delay discounting, and negative associations between quality of life and treatment effectiveness with these outcomes were observed. CONCLUSIONS: This study examined longer term OUD recovery outcomes. Participants reported high levels of abstinence from opioids and psychosocial functioning. These encouraging results highlight the multidimensional nature of recovery from OUD, and further support the effectiveness of buprenorphine as an OUD treatment.

ABSTRACT

BACKGROUND: This work evaluated the psychometric properties of the single-item Opioid Craving Visual Analog Scale (OC-VAS) for opioid use disorder (OUD). METHODS: Psychometric evaluation of the OC-VAS (range: 0-100 mm) was supported by Subjective Opiate Withdrawal Scale (SOWS) item 16 and total score, Clinical Opiate Withdrawal Scale (COWS) scores, and the 36-Item Short-Form Health Survey, using data from phase 3 study (NCT02357901; N = 487) participants who received randomized treatment and completed the OC-VAS at screening. Descriptive properties, test-retest reliability, construct validity, known-groups validity, and responsiveness were assessed. Interpretation of meaningful change and predictive validity were also explored. RESULTS: Descriptive properties for the OC-VAS at screening did not provide evidence of problematic floor/ceiling effects or missingness. The test-retest reliability was established by weekly intraclass correlations >0.70. At the screening and end of the study, the strong positive correlations between OC-VAS and SOWS Total/Item 16 score and the significant OC-VAS differences among COWS severity groups supported construct validity and known-groups (discriminating ability) validity, respectively. The associations between the changes in OC-VAS and in supporting measures/opioid use from screening to the end of the study demonstrated responsiveness and the ability to detect change in clinical status. During the induction and randomization treatment periods, significant relationships were identified between OC-VAS score and subsequent opioid use. CONCLUSIONS: This psychometric evaluation of the OC-VAS performed on a large OUD patient population provides evidence to support its use to measure the severity of opioid craving and its ability to predict opioid use.

ABSTRACT

Background: Positive and Negative Syndrome Scale (PANSS) data from a pivotal phase 3 study in participants with schizophrenia of RBP-7000, a recently marketed long-acting subcutaneous injectable risperidone formulation, were examined to determine if dose-response relationships existed for different items of the PANSS.Methods: Changes in the 30 PANSS items were analyzed individually and using the 5 factor-analysis-derived dimensions defined by Marder and colleagues. Subgroups of patients who could benefit from the RBP-7000 120 mg dose were investigated.Results: 337 participants were randomized and received study medication (RBP-7000 90 mg n = 111, RBP-7000 120 mg n = 114, placebo n = 112). Dose-dependent responses were observed in items from the study-specified PANSS positive and general psychopathology exploratory subscales. Dose-dependent responses were observed across all 5 Marder dimensions, with the largest effect sizes observed with the 120 mg dose in the uncontrolled hostility/excitement (UHE) and anxiety/depression dimensions. Participants with baseline UHE dimension scores ≥ 9 demonstrated greater improvement in PANSS total score at the 120 mg dose compared to the 90 mg dose.Conclusions: RBP-7000 demonstrated efficacy across both the primary and exploratory PANSS study endpoints and the post hoc Marder dimensions. Schizophrenia patients with higher baseline Marder UHE scores may benefit from initiation of treatment at the 120 mg dose.Trial Registration: ClinicalTrials.gov identifier: NCT02109562.

ABSTRACT

BACKGROUND: Buprenorphine treatment is not equally effective in all patients with opioid use disorder (OUD). Two retrospective studies showed that, among African Americans (AAs), rs678849, a polymorphism in the delta-opioid receptor gene, moderated the therapeutic effect of sublingual buprenorphine. METHODS: We examined rs678849 as a moderator of the response to an extended-release subcutaneous buprenorphine formulation (BUP-XR) in a 24-week OUD treatment study of 127 AAs and 327 European Americans (EAs). Participants were randomly assigned to receive: (1) BUP-XR as 2 monthly injections of 300 mg followed by either 300 mg monthly or 100 mg monthly for 4 months, or (2) monthly volume-matched placebo injections. Generalized estimating equations logistic regression analyses tested, per population group, the main and interaction effects of treatment (BUP-XR vs placebo) and genotype group (rs678849*CC vs CT/TT) on weekly urine drug screens (UDS). RESULTS: Among AAs, the placebo group had higher rates of opioid-positive UDS than the BUP-XR group (log odds ratio = 1.67, 95% CI = 0.36, 2.98), but no genotype by treatment effect (P = .80). Among EAs, the placebo group also showed higher rates of opioid-positive UDS than the BUP-XR group (log odds ratio = 1.97, 95% CI = 1.14, 2.79) but a significant genotype by treatment interaction (χ 2(1) = 4.33, P = .04). CONCLUSION: We found a moderating effect of rs678849 on the response to buprenorphine treatment of OUD in EAs, but not AAs. These findings require replication in well-powered, prospective studies of both AA and EA OUD patients treated with BUP-XR and stratified on rs678849 genotype.

ABSTRACT

BACKGROUND: Drug exposure and corresponding antisecretory effects increase over the first 4-5 days of esomeprazole treatment. To date, this effect has not been correlated with symptomatic improvement. Therefore, the efficacy of esomeprazole was evaluated on days 1-4 and 5-14 using pooled data from two identical randomised, double-blind, placebo-controlled studies conducted in subjects with frequent heartburn who are likely to self-treat with over-the-counter medications. METHODS: Adults without confirmed diagnoses of gastro-oesophageal reflux disease experiencing heartburn 2 or more days per week in the past 4 weeks were randomly assigned to treatment with esomeprazole 20 mg or placebo once daily for 14 days following a 1-week placebo run-in period (esomeprazole: n=330; placebo: n=321). Heartburn episodes were documented in daily diaries. The current analyses evaluated the change in baseline percentage of heartburn-free days across days 1-4 and 5-14. RESULTS: Change in the percentage of heartburn-free days from the run-in was significantly greater with esomeprazole compared with placebo (p<0.001) starting on days 1-4. The greatest treatment benefit was observed during days 5-14. During this period, esomeprazole-treated subjects increased their heartburn-free time over the run-in period by 32.5% compared with 14.3% with placebo (p<0.001). CONCLUSIONS: Frequent heartburn sufferers treated with esomeprazole 20 mg had significantly more heartburn-free days relative to placebo throughout the studies. Maximal clinical benefits coincided with the estimated timing of maximal pharmacokinetic and pharmacodynamic effects and duration of acid control on days 5-14. TRIAL REGISTRATION NUMBER: NCT01370525; NCT01370538.

ABSTRACT

BACKGROUND: A two-week course of therapy with an over-the-counter proton-pump inhibitor (PPI) is recommended for frequent heartburn. Limited research has been conducted on the sustained efficacy of short-term PPI therapy after treatment cessation. Esomeprazole 20 mg was evaluated in the seven-day follow-up period after the two-week treatment period using pooled data from two identical randomized, double-blind, placebo-controlled studies. METHODS: Adults without confirmed diagnoses of gastroesophageal reflux disease experiencing heartburn at least two days/week in the past four weeks were eligible. Subjects received treatment with esomeprazole 20 mg or placebo once daily for 14 days. Heartburn episodes were documented using daily diaries. Missing data during the two-week treatment period were assumed to be days with heartburn. The proportion of subjects with heartburn resolution while on treatment and during the seven days of follow-up was assessed. Predictors of resolution during this post-treatment period were evaluated using a stepwise logistic regression model. RESULTS: All subjects in the pooled analysis set who reported diary data for at least three follow-up days were analyzed (N = 584). This cut-off was used to ensure that sufficient data were collected for these analyses. Greater run-in heartburn frequency was a significant negative predictor of heartburn resolution during follow-up (P < 0.001). Among the on-treatment efficacy variables, the best predictor of resolution during follow-up was resolution during the last seven days of treatment (odds ratio: 3.81 [95% confidence interval: 2.40, 6.05; P < 0.0001]). CONCLUSIONS: Lower baseline heartburn frequency and heartburn resolution during the last seven days of treatment were associated with a greater likelihood of heartburn resolution during the seven-day follow-up. TRIAL REGISTRATION: Registered at ClinicalTrials.gov June 11, 2011: NCT01370525 ; NCT01370538 .

ABSTRACT

PURPOSE: These secondary analyses used data from 2 similarly designed studies in subjects experiencing frequent heartburn to evaluate the efficacy of esomeprazole 20 mg once daily for 2 weeks, which reflects the approved over-the-counter dosage and duration. METHODS: Subjects without endoscopically identified erosive esophagitis who were experiencing heartburn for ≥6 months and ≥4 of 7 days prior to baseline (study 1, N = 368; study 2, N = 349) were randomly assigned to receive double-blind treatment with esomeprazole 40 or 20 mg (administered as esomeprazole magnesium trihydrate 44.5 and 22.3 mg, respectively) or placebo once daily for 4 weeks. Subjects recorded the severity of heartburn in a daily diary, and investigators assessed subjects at each study visit. Two-week assessments were the primary end points of interest in these analyses and included the percentage of subjects with complete heartburn resolution (no episodes during 7 consecutive days), time to sustained complete heartburn resolution (the first of 7 consecutive episode-free days), and heartburn relief (no episodes other than ≤1 mild episode during 7 consecutive days). FINDINGS: At week 2, the percentages of subjects who experienced complete heartburn resolution were significantly greater with esomeprazole 40 mg (study 1, 26.1%; study 2, 35.3%) and 20 mg (study 1, 25.2%; study 2, 35.7%) compared with placebo (study 1, 9.0%; study 2, 3.4%) (all, P ≤ 0.001). Beginning on day 1, the percentages of subjects who experienced sustained heartburn resolution was significantly greater in the groups treated with esomeprazole 40 mg (study 1, 19%; study 2, 19%; P < 0.0001) and 20 mg (study 1, 10%; study 2, 15%; P < 0.05) compared with the group that received placebo (study 1, 2%; study 2, 1%). Additionally, at week 2, the percentages of subjects experiencing heartburn relief were significantly greater with esomeprazole 40 mg (study 1, 35.3%; study 2, 40.5%) and 20 mg (study 1, 34.5%; study 2, 46.4%) compared with placebo (study 1, 16.5%; study 2, 8.6%) (all, P ≤ 0.001). IMPLICATIONS: The results of this study demonstrate that once-daily treatment with esomeprazole 20 mg for 2 weeks effectively resolved subjects׳ heartburn compared with placebo, beginning on day 1. Studies precede FDA Act 801 clinical trial registration and results submission requirements.

ABSTRACT

BACKGROUND: Dietary or supplementary intake of nutrients and other ingredients positively affects skin appearance. AIMS: Evaluate a multicomponent nutritional supplement on photoaged skin. PATIENTS/METHODS: This multicenter, double-blind, placebo-controlled trial randomized healthy 35- to 65-year-old women with Fitzpatrick skin types I-IV and Glogau classification types II-III to a multicomponent nutritional supplement or placebo for 24 weeks. The primary endpoint was Investigator Global Assessment of overall facial appearance at week 24. Secondary endpoints included investigator- and subject-rated assessments of the face, décolletage, and hands; facial photography assessments (conducted by an independent panel of dermatologists); and instrumental measures. Analysis of variance was used to assess between-group differences (P ≤ 0.05). RESULTS: Of 194 randomized subjects, 171 completed the study. Subjects had a mean age of 53 years and were primarily white (81%), had Glogau II (58%) and Fitzpatrick III (45%; significantly more supplement subjects had Fitzpatrick III [54%] vs. placebo [35%]; P = 0.039). At week 24, Investigator Global Assessment of overall facial appearance was numerically but not statistically better for supplement over placebo (mean difference: 0.14 [95% confidence interval: -0.16-0.44]; P = 0.358). A significant treatment-by-site interaction (P = 0.073) was observed; by-site analyses revealed a significant difference at one of three geographical sites for supplement vs. placebo (P = 0.001). Differences on secondary endpoints were generally not significant. CONCLUSIONS: In the first multicenter study conducted with this multicomponent nutritional supplement, no significantly greater effects vs. placebo were observed on the primary endpoint, perhaps because of significant between-site variability.

ABSTRACT

OBJECTIVES: Esomeprazole 20 mg once daily has been shown to be effective for treating frequent heartburn over 14 days in subjects who are likely to self-treat with over-the-counter medications. These analyses were conducted to assess durability of effects and symptomatic rebound after cessation of treatment, treatment satisfaction, and rescue antacid use with esomeprazole 20 mg once daily for 14 days. METHODS: Adults with frequent heartburn (≥ two days/week in the past four weeks) were randomly assigned to 14 days of double-blind treatment with esomeprazole 20 mg or placebo in two identical multicenter studies. All subjects entered a 1-week single-blind placebo follow-up period after treatment. The results of the primary efficacy endpoints were reported previously. The percentage of heartburn-free days during the 1-week follow-up, use of rescue antacids, and treatment satisfaction, measured with the Global Assessment Questions instrument, are described. RESULTS: The percentage of heartburn-free days was maintained during the 1-week follow-up period; the proportion was 43% among esomeprazole subjects in these studies, suggesting no evidence of symptomatic rebound. Rescue antacid use generally decreased compared with the run-in period in the 14-day treatment and 1-week follow-up periods. Significantly more subjects taking esomeprazole were "very satisfied" or "satisfied" with treatment versus placebo (Study 1: 78% vs. 63%, respectively, P = 0.0038; Study 2: 81% vs. 60%, respectively, P = 0.0002). CONCLUSIONS: Subjects who are likely to self-treat their frequent heartburn with over-the-counter medications reported satisfaction with esomeprazole 20 mg. Esomeprazole's treatment effect was maintained for ≥ one week after treatment ended, with no sign of symptomatic rebound. These trials were registered at ClinicalTrials.gov: NCT01370525; NCT01370538.

ABSTRACT

BACKGROUND AND OBJECTIVE: Sleep disturbances related to reflux symptoms have a significant impact on the daily lives of affected individuals. These analyses identified clinical factors related to resolution of reflux-related sleep disturbance in subjects treated with esomeprazole 20 mg for 14 days. METHODS: Data from the first 14 days of 2 similar randomized, double-blind studies were pooled for subjects experiencing frequent heartburn and related sleep disturbances receiving esomeprazole 20 mg (n = 357) or placebo (n = 346). A stepwise logistic regression analysis was performed with pooled and individual study data to evaluate relationships between clinical factors [treatment (esomeprazole vs. placebo), run-in sleep disturbance frequency, occurrence (yes/no) of 24-h, daytime, and nighttime heartburn (yes: ≥1 episode in 14-day treatment period)] and complete sleep disturbance resolution (no disturbances for 7 consecutive days). RESULTS: Absence of daytime (p = 0.0018) or nighttime (p < 0.0001) heartburn during treatment was a significant predictor of complete sleep disturbance resolution at 14 days for the total population, while higher run-in sleep disturbance frequency (p < 0.0001) was associated with a lower likelihood of resolution. Esomeprazole treatment was an independent significant predictor of improvement across all endpoints (p < 0.0001). A significant treatment by run-in sleep disturbance interaction was observed for complete resolution (p = 0.0231), indicating greater therapeutic benefit with esomeprazole in subgroups with higher run-in symptom frequency. CONCLUSIONS: Lower run-in sleep disturbance frequency, no occurrence of daytime or nighttime heartburn during therapy, and esomeprazole treatment predicted complete reflux-related sleep disturbance resolution. The magnitude of therapeutic benefit for esomeprazole 20 mg over placebo increased with increasing baseline sleep disturbance.

ABSTRACT

OBJECTIVE: To assess the efficacy of Imedeen Time Perfection for improving the appearance and condition of photoaged skin in healthy women. METHODS: This randomized, double-blind, placebo-controlled clinical trial enrolled healthy women, 35-60 years of age, with Fitzpatrick I-III and Glogau II-III skin types and mild-to-moderate facial fine lines/wrinkles. The eligible subjects were randomized to receive two tablets daily of either Imedeen Time Perfection (Imedeen) or a matching placebo for 12 weeks. Efficacy assessments included investigator rating of 16 photoaging parameters (ie, global facial appearance and 15 individual facial parameters and the average of all parameters), instrumentation (ie, ultrasound dermal density, moisture level of the stratum corneum, transepidermal water loss, cutometry), and subjects' self-assessment. Differences in the mean change from baseline to week 12 values on these outcomes were compared between Imedeen and placebo using analysis of variance or a paired t-test. RESULTS: Seventy-four subjects with primarily Fitzpatrick skin type III (78%-79%) and Glogau type III (53%-58%) completed the study (Imedeen: n=36; placebo: n=38). The mean difference in change from baseline to week 12 for global facial assessment significantly favored Imedeen over placebo (-0.52; P=0.0017). Additionally, the mean differences in the average of all facial photoaging parameters (-0.29), mottled hyperpigmentation (-0.25), tactile laxity (-0.24), dullness (-0.47), and tactile roughness (-0.62) significantly favored Imedeen over placebo (P≤0.05). Significantly greater increases in ultrasound dermal density (+11% vs +1%; P≤0.05) and stratum corneum moisturization (+30% vs +6%; P≤0.05) were also observed for Imedeen than for placebo. There were no significant differences on other instrumental outcomes. CONCLUSION: The results of this study suggest that Imedeen Time Perfection can positively affect the appearance of photoaged skin, moisturization, and skin density over 12 weeks of treatment.

ABSTRACT

Although the FDA does not require documentation of efficacy of dietary supplements, prospective clinical studies, including randomized controlled trials, have been conducted with individual micronutrients alone and in combination with other ingredients for promoting skin health. Proposed mechanisms include antioxidation, anti-inflammation, photoprotection, collagen formation, reductions in matrix metalloproteinases, and other effects on photoaging. Literature searches were conducted to identify clinical trials assessing multicomponent dietary supplement formulations on photoaging outcomes. Sixteen studies of various nutrient and non-nutrient ingredients, including essential micronutrients (vitamins, minerals), plant extracts (polyphenols, carotenoids), and marine- or animal-derived ingredients, were identified. Studies were single center, 2-12 months in duration, primarily enrolled women, and evaluated numerous outcomes, including investigator/subject assessments and instrumental/objective measures. Methods to control for potential confounders were implemented in some studies, including limiting sun exposure, cosmetic procedures, and changes in dietary habits/body weight. Given the range of different products, clinical/methodologic heterogeneity, insufficient detail in reporting, and lack of comparable outcome measures, quantitative analysis of results was not possible. Results of individual studies revealed significant improvements from baseline for the dietary supplement group(s) on ≥ 1 endpoint across all studies; significant differences from placebo were observed in 7 of 12 controlled studies (although only 1 study designated a prospectively defined primary endpoint). Most products had only been tested in 1 study; confirmatory studies were rarely conducted per the publicly available literature. Meaningful assessment of dietary supplements, which typically contain nutrients found in the diet, requires unique methodologic considerations and endpoints appropriate for measuring changes that are more subtle and gradual than those observed with topical/injectable products. Although definitive conclusions could not be drawn from the existing evidence, available data are supportive of beneficial effects of oral multicomponent supplements on skin health. Confirmation of positive effects with the same formulation/endpoint from more than a single study/investigator is needed.

ABSTRACT

OBJECTIVE: To investigate the resolution of heartburn and gastroesophageal reflux disease (GERD)-related sleep disturbances during the first 14 days of treatment with esomeprazole 20 mg compared to placebo in subjects with frequent nighttime heartburn and GERD-related sleep disturbances. RESEARCH DESIGN AND METHODS: This was a post hoc analysis of 2 week data from two previously published, similarly designed randomized, placebo-controlled trials of 4 weeks' duration comparing esomeprazole 20 mg, 40 mg (one study), and placebo. Inclusion and exclusion criteria for both trials were the same. CLINICAL TRIAL REGISTRATION: NCT00628342; NCT00660660. MAIN OUTCOME MEASURES: The main outcome measures for this analysis were the resolution and/or relief of GERD-related sleep disturbances during 2 weeks of treatment with esomeprazole 20 mg or placebo. Resolution and/or relief of heartburn symptoms were also measured. RESULTS: In trial 1, 455 subjects were randomized, with 225 and 229 receiving esomeprazole 20 mg and placebo, respectively. In trial 2, 276 subjects were randomized, with 142 and 132 receiving esomeprazole and placebo, respectively. After 2 weeks, significantly more subjects who received esomeprazole 20 mg (50.5% [95% confidence interval: 43.8%-57.1%] and 39.4% [31.2%-47.6%] in trials 1 and 2, respectively) had resolution of sleep disturbances compared to placebo (19.9% [14.6%-25.2%] and 16.0% [9.6%-22.4%], respectively; p < 0.0001 for both trials). The median time to resolution of sleep disturbances with esomeprazole 20 mg was 1 day in both trials. After 2 weeks, significantly more subjects receiving esomeprazole 20 mg (32.3% [26.1%-38.5%] and 26.3% [18.9%-33.6%] in trials 1 and 2, respectively) had resolution of nighttime heartburn symptoms compared to placebo (5.4% [2.4%-8.4%] and 4.8% [1.1%-8.5%], respectively; p < 0.0001 for both trials). CONCLUSIONS: Esomeprazole 20 mg significantly and effectively reduced nighttime heartburn and GERD-related sleep disturbances in the first 2 weeks of treatment compared to placebo, with rapid resolution of sleep disturbances in the first days of treatment.
