Efficacy, Safety, Patient Experience, and Tolerability of Risankizumab Administered by On-Body Injector for Moderate to Severe Crohn's Disease.

ABSTRACT:

Introduction

In patients with moderate to severe Crohn's disease (CD), intravenous induction and subcutaneous maintenance dosing with risankizumab was efficacious and well tolerated. Long-term management of CD via self-administration of risankizumab using an on-body injector (OBI) may improve treatment adherence through convenience and ease of use.

Methods

Within the FORTIFY maintenance study, 46 patients from the United States (US) sites participated in an open-label extension Substudy and received 180 mg or 360 mg risankizumab delivered subcutaneously via OBI [360 mg (2.4 mL, 150 mg/mL) or 180 mg (1.2 mL, 150 mg/mL)]. At the Week 0 visit, patients were trained (pre-injection) by site staff, using Instructions for Use (IFU) and a training video, to self-administer risankizumab at Weeks 0 (on site), 8 (at home), and 16 (on site). Key objectives of the Substudy 4 were to assess OBI usability (observer rating of successful self-administration), hazard-free self-injection at Weeks 0 and 16, and patient rating of acceptability using the Self-Injection Assessment Questionnaire (SIAQ) at Weeks 0, 8, and 16. Additionally, the proportion of patients in clinical remission (CD Activity Index < 150) was collected at Weeks 0 and 16.

Results

All patients successfully self-administered risankizumab via OBI, including two patients who successfully self-administered with a second OBI (i.e., required two injection attempts). Acceptability of self-injection was high. Two patients (n = 2) experienced a use-related hazard. Stable clinical remission was observed with both risankizumab doses. Two patients experienced injection site reactions; neither was related to the OBI per investigator's assessment. Two device-related adverse events related to topical adhesive reactions were reported, both mild and resolved. No new safety risks were observed.

Conclusion

The efficacy and safety of maintenance risankizumab delivered via OBI and OBI usability support the use of this device in patients with moderate to severe CD.

Project description:BackgroundDonepezil 23 mg/d, recently approved in the United States for treatment of moderate to severe Alzheimer's disease (AD), was developed to address the need for an additional treatment option for patients with advanced AD. This report, based on a pivotal phase 3 study, presents a detailed analysis of the safety and tolerability of increasing donepezil to 23 mg/d compared with continuing 10 mg/d.MethodSafety analyses comprised examination of the incidence, severity, and timing of treatment-emergent adverse events (AEs) and their relationship to treatment initiation; changes in weight, electrocardiogram, vital signs, and laboratory parameters; and the incidence of premature study discontinuation. The analysis population (n = 1434) included all randomized patients who took at least 1 dose of study drug and had a postbaseline safety assessment. To further examine the effect of transition from a lower to a higher donepezil dose, a pooled analysis of safety data from 2 phase 3 trials of donepezil 5 mg/d and 10 mg/d was also performed.ResultsThe safety population comprised 1434 patients: donepezil 23 mg/d (n = 963); donepezil 10 mg/d (n = 471); completion rates were 71.1% and 84.7%, respectively. The most common AEs were nausea, vomiting, and diarrhea (donepezil 23 mg/d: 11.8%, 9.2%, 8.3%; donepezil 10 mg/d: 3.4%, 2.5%, 5.3%, respectively). AEs that contributed most to early discontinuations were vomiting (2.9% of patients in the 23 mg/d group and 0.4% in the 10 mg/d group), nausea (1.9% and 0.4%), diarrhea (1.7% and 0.4%), and dizziness (1.1% and 0.0%). The percentages of patients with AEs in the 23 mg/d group, as well as the timing, type, and severity of these AEs, were similar to those seen in previous donepezil trials with titration from 5 to 10 mg/d. Serious AEs were uncommon (23 mg/d, 8.3%; 10 mg/d, 9.6%).DiscussionThe 23 mg/d dose of donepezil was associated with typical cholinergic AEs, particularly gastrointestinal-related AEs, similar to those observed in studies with a dose increase from 5 to 10 mg/d.ConclusionThe good safety and predictable tolerability profile for donepezil 23 mg/d supports its favorable risk/benefit ratio in patients with moderate to severe AD.
