Long-term persistence and other treatment patterns among bio-naïve patients with Crohn's disease treated with ustekinumab or adalimumab.

OBJECTIVE: To estimate long-term persistence among bio-naïve patients with CD initiated on ustekinumab or adalimumab. METHODS: Adults with CD initiating ustekinumab or adalimumab (index date, between September 23, 2016 and August 1, 2019) were sampled from the IBM MarketScan Commercial Database. Patients without CD-indicated biologics (bio-naïve) and with no diagnoses for other autoimmune diseases 12 months pre-index date (baseline) were included. Cohorts were balanced on baseline characteristics with inverse probability of treatment weighting. Persistence was defined as the absence of therapy exposure gaps >120 days (ustekinumab) or >60 (adalimumab) between days of supply. Composite endpoints were persistence and being corticosteroid-free (no corticosteroids >14 days of supply after day 90 post-index) and persistence while on monotherapy (no immunomodulators/non-index biologics). Persistence was analyzed using Kaplan-Meier and Cox's models. RESULTS: Ustekinumab and adalimumab cohorts included 671 and 2,975 patients. At 12 months post-index, ustekinumab patients were significantly more persistent (hazard ratio [HR] = 1.60; 95% confidence interval [CI] = 1.33-1.93), persistent while on monotherapy (HR = 1.43; 95% CI = 1.24-1.65), and trended toward being more persistent and corticosteroid-free (HR = 1.14; 95% CI = 0.99-1.30) vs adalimumab. At 24 months post-index, ustekinumab patients were significantly more persistent (HR = 1.66; 95% CI = 1.40-1.97), persistent while on monotherapy (HR = 1.44; 95% CI = 1.26-1.64), and persistent and corticosteroid-free (HR = 1.15; 95% CI = 1.01-1.31) vs adalimumab. CONCLUSIONS: Bio-naïve patients with CD initiated on ustekinumab demonstrated significantly more persistence than patients initiated on adalimumab at 12 and 24 months of treatment. Long-term persistence is a measure of a drug's real-world performance and findings may aid clinical decision-making.

Choosing a treatment on which a patient can stay over a long period of time is key for the successful management of chronic conditions such as Crohn's disease. Information on whether and how long patients stay on treatment can help physicians make the right therapeutic choice. This study examined whether adults with Crohn's disease, who have not previously taken biologics, stay on treatment longer when given the biologic ustekinumab or adalimumab. At 12 and 24 months after starting the treatment, a larger proportion of patients were still using ustekinumab compared with adalimumab. The proportion of patients using the biologic without immunomodulators or other biologics was also higher with ustekinumab. The results suggest that patients without previous biologic experience stay on treatment longer with ustekinumab than with adalimumab.

Continuity of care among patients newly initiated on second-generation oral or long-acting injectable antipsychotics during a schizophrenia-related inpatient stay.

BACKGROUND: Maintaining continuity of care after schizophrenia-related hospitalization is challenging for patients and healthcare providers and systems. Prior evidence suggests that second-generation long-acting injectable antipsychotics (SGLAIs) may reduce the risk of treatment nonadherence and readmission versus oral atypical antipsychotics (OAAs). Therefore, quality measures were compared between patients initiated on SGLAIs and OAAs in the United States. METHODS: Adults newly initiated on an SGLAI or OAA during a schizophrenia-related inpatient stay were identified in HealthVerity databases (01/2015-12/2020); the index date was the hospital discharge date. Patients had continuous health insurance coverage for pharmacy and medical services for 6 months pre-admission and post-discharge from the inpatient stay and ≥1 pharmacy or medical claim (i.e. treatment as indicated by the observed insurance claims) for an antipsychotic other than the index SGLAI or OAA in the 6 months pre-admission. Antipsychotic use and adherence, and schizophrenia-related readmissions and outpatient visits were compared during the 6-month period post-discharge. Characteristics between cohorts were balanced using inverse probability weights. RESULTS: Post-discharge, only 36.9% and 40.7% of weighted SGLAI (N = 466) and OAA (N = 517) patients had ≥1 pharmacy or medical claim for the antipsychotic initiated during the inpatient stay, among whom SGLAI patients were 4.4 times more likely to be adherent to that antipsychotic compared to OAA patients (p < .001). Additionally, SGLAI patients were 2.3 and 3.0 times more likely to have a pharmacy or medical claim for and be adherent to any antipsychotic relative to OAA patients (including index antipsychotic; all p < .001). Within 7 and 30 days post-discharge, 1.7% and 13.0% of SGLAI patients and 4.1% and 12.6% of OAA patients had a readmission. Further, SGLAI patients were 51% more likely to have an outpatient visit compared to OAA patients (p = .044). CONCLUSIONS: Less than half of patients initiated on antipsychotics during a schizophrenia-related inpatient stay continued the same treatment post-discharge. However, SGLAI patients were more likely to be adherent to the initiated antipsychotic and to have an outpatient visit, which may suggest improved continuity of care post-discharge relative to OAA patients.

Persistence Among Patients with Crohn Disease Previously Treated with an Anti-tumor Necrosis Factor Inhibitor and Switching or Cycling to Another Biologic Agent.

PURPOSE: Nonresponse to an anti-tumor necrosis factor (TNF) agent in patients with Crohn disease (CD) is often managed by either a switch to a different class of biologic (ie, ustekinumab, vedolizumab) or by cycling to another anti-TNF agent (ie, adalimumab, infliximab, certolizumab pegol). Persistence after a switch to a different biologic class or after cycling within the anti-TNF class was assessed in patients with nonresponse to an anti-TNF agent. METHODS: Adults with CD who discontinued from an anti-TNF agent and either switched to a different class of biologic (ie, anti-interleukin/integrin; the switching cohort) or cycled within the anti-TNF class (the cycling cohort) between September 23, 2016, and August 1, 2019, were selected from a commercial database. The index date was defined as the date of the first claim of the subsequent-line biologic (index biologic) after an anti-TNF. The switching and cycling cohorts were balanced with regard to baseline characteristics, using inverse probability of treatment weights-average treatment effect (IPTW-ATE). Persistence with the index biologic was defined as consistent use with no gaps of >120 days (ustekinumab, vedolizumab, infliximab) or of >60 days (adalimumab, certolizumab pegol) in biologic supply. Composite end points were persistence while being corticosteroid-free (defined as no use of corticosteroids with ≥14 days of supply after day 90 post-index) and persistence while on monotherapy (no immunomodulators/nonindex biologics). Weighted Kaplan-Meier and Cox models were used to assess outcomes at 12 months post-index. FINDINGS: There were 444 patients in the weighted switching cohort (mean age, 40.4 years; 56.3% female) and 441 in the weighted cycling cohort (mean age, 39.5 years; 58.4% female). At 12 months post-index, the rate of persistence with the index biologic was 75.7% in the switching cohort compared to 67.5% in the cycling cohort (log-rank P = 0.023); the rate of persistence while on monotherapy was 58.2% compared to 44.2%, respectively (log-rank P < 0.001). The rate of persistence was 44% greater in the switching compared to that in the cycling cohort (hazard ratio [HR] = 1.44; 95% CI, 1.11-1.88; P = 0.007); the rate of persistence while on monotherapy was 56% greater in the switching cohort (HR = 1.56; 95% CI, 1.28-1.90; P < 0.001). The between-cohort difference in persistence while being corticosteroid-free was not statistically significant (HR = 1.08; 95% CI, 0.89-1.32; P = 0.426). IMPLICATIONS: Patients with CD who switched to a different biologic class were more persistent than were patients who cycled to another anti-TNF agent. These findings may be useful for physicians when considering the treatment of patients who have experienced nonresponse or loss of response to the first-line anti-TNF agent.

Persistence and other treatment patterns among bio-experienced patients with Crohn's disease initiated on ustekinumab or adalimumab.

BACKGROUND: Real-world data on persistence on ustekinumab and adalimumab among bio-experienced patients with Crohn's disease (CD) are limited. OBJECTIVE: To compare treatment persistence and describe switching, restart, and dose titration among bio-experienced patients with CD initiated on ustekinumab or adalimumab. METHODS: IBM MarketScan Commercial Database was used to identify bio-experienced adults with CD who were assigned to either the ustekinumab or adalimumab cohort based on the agent first initiated (index date) after September 23, 2016. Cohorts were balanced using inverse probability of treatment weights-average treatment effect on treated. Persistence on index agent (absence of exposure gap > 120 days for ustekinumab or > 60 days for adalimumab), persistence while corticosteroid-free, and persistence while receiving monotherapy were assessed at 12 months after index date and compared between cohorts using weighted Kaplan-Meier and Cox proportional hazards model analyses. RESULTS: Among 903 patients in the ustekinumab cohort and 525 patients in the adalimumab cohort, baseline characteristics were balanced after weighting. At 12 months post-index, ustekinumab was associated with higher persistence (80.1% vs 64.6%; hazard ratio = 2.02 [95% CI = 1.60-2.56]; P < 0.001) and persistence while receiving monotherapy (51.6% vs 40.0%; 1.51 [1.28-1.78]; P < 0.001) vs adalimumab. Persistence while corticosteroid-free was similar in the ustekinumab vs adalimumab cohort (50.1% vs 48.2%; 1.19 [1.00-1.41]; P = 0.0516). CONCLUSIONS: This retrospective real-world study demonstrated that among bio-experienced patients with CD, initiation of ustekinumab was associated with better persistence at 12 months of follow-up, including persistence while receiving monotherapy, compared with adalimumab.

Treatment patterns, healthcare utilization, and costs of patients with treatment-resistant depression initiated on esketamine intranasal spray and covered by US commercial health plans.

AIMS: To describe real-world use of esketamine (ESK) intranasal spray and healthcare outcomes among patients with treatment-resistant depression (TRD) in the United States (US). METHODS: Adults with TRD initiated on ESK (index date) between 5 March 2019 (US approval date for TRD) and 31 October 2020 were sampled from IBM MarketScan Research Databases. TRD was defined as claims for ≥2 unique antidepressants during the same major depressive episode. Subgroups of the TRD cohort with comorbid cardiometabolic conditions, pain, anxiety disorder, and substance use disorder (SUD) were identified. Patients had ≥6 months of continuous health plan eligibility pre- and post-index. RESULTS: The TRD cohort comprised 269 patients; comorbidity subgroups included 123 (cardiometabolic), 144 (pain), 189 (anxiety disorder), and 58 (SUD) patients. Proportion of patients completing ≥8 ESK sessions (number of sessions in induction phase) was 61.3% in the TRD cohort and ranged from 60.2% (cardiometabolic subgroup) to 72.4% (SUD subgroup) in subgroups. Median frequency of induction sessions was every 5-8 days among the TRD cohort and subgroups. Mean mental health-related inpatient costs reduced from pre- to post-index periods in the TRD cohort (mean ± standard deviation [median] costs per-patient-per-6-months: $3,480 ± $13,328 [$0] pre-ESK initiation; $3,262 ± $16,666 [$0] post-ESK initiation; mean difference: -$218) and subgroups (largest decrease in cardiometabolic subgroup: $4,864 ± $14,271 [$0]; $2,792 ± $15,757 [$0]; -$2,072). Mean mental health-related emergency department (ED) costs decreased in the TRD cohort ($608 ± $2,525 [$0]; $269 ± $1,143 [$0]; -$339) and subgroups (largest decrease in the SUD subgroup: $1,403 ± $3,752 [$0]; $351 ± $868 [$0]; -$1,052). LIMITATIONS: This is a descriptive analysis; sample size for some comorbidity subgroups is small. CONCLUSIONS: The majority of patients completed ESK induction phase, and most dosing intervals were longer than the label recommendation. In this descriptive analysis, mental health-related inpatient and ED costs trended lower post-ESK initiation.

Treatment persistence among bio-naïve patients with Crohn's disease initiated on ustekinumab or adalimumab.

OBJECTIVES: To compare persistence and describe dose titration among bio-naïve patients with Crohn's disease (CD) initiated on ustekinumab or adalimumab. METHODS: Bio-naïve adults with CD who initiated ustekinumab or adalimumab (index date) from 23 September 2016 (ustekinumab US approval for CD) to 1 August 2019 were selected from IQVIA PharMetrics Plus. Cohorts were balanced on baseline characteristics measured over 12 months pre-index using inverse probability of treatment weights. Persistence was defined as no gaps (ustekinumab: >120 days; adalimumab: >60 days) between days of supply. Dose escalation was defined as ≥2 consecutive sub-cutaneous claims 100% above the US label daily dose in the maintenance phase; de-escalation was a return to the daily dose for ≥2 consecutive claims. Outcomes were described using weighted Kaplan-Meier models; persistence outcomes were compared using Cox's proportional hazards models. RESULTS: At 12 months post-index, patients in the ustekinumab (n = 948) versus adalimumab (n = 4143) cohort had a significantly higher rate of persistence on index biologic (hazard ratio [HR] 1.50; 95% confidence interval [CI]: 1.29-1.74). A total of 830 (87.6%) patients in the ustekinumab cohort and 3713 (89.6%) in the adalimumab cohort began the maintenance phase; within 12 months, 11.2% and 16.9%, underwent a dose escalation, and 26.6% and 6.3%, respectively, subsequently de-escalated to the per US label daily exposure. CONCLUSIONS: Bio-naïve patients with CD initiated on ustekinumab were more persistent than patients initiated on adalimumab; moreover, these patients had numerically lower dose escalation and higher de-escalation rates than patients initiated on adalimumab. Findings support the use of ustekinumab as a first-line treatment for bio-naïve patients with CD.
