Background: Patients with psoriasis are at increased risk of liver function abnormalities., Objective: Explore rates of hepatic treatment-emergent adverse events (TEAEs) and changes in liver parameters in bimekizumab-treated patients with psoriasis., Methods: Data are reported from 5 phase 3/3b trials over 2 years. Hepatic TEAEs, laboratory elevations in alanine aminotransferase (ALT) or aspartate aminotransferase (AST), and changes in clinical markers of liver fibrosis (Fibrosis-4 [FIB-4] Index and AST to Platelet Ratio Index [APRI]) are reported. TEAEs are presented using exposure-adjusted incidence rates (EAIRs) per 100 patient-years (PY)., Results: 2186 patients received ≥1 bimekizumab dose. Over 2 years, the EAIR of hepatic TEAEs was 3.5/100 PY and did not increase from first to second year. 2-year EAIRs of ALT/AST elevations >3x and >5x the upper limit of normal were 2.3 and 0.6/100 PY; rates were similar to placebo, adalimumab, secukinumab, and ustekinumab during controlled study periods. FIB-4 and APRI scores did not increase through 2 years, regardless of fibrosis risk at baseline., Limitations: Obesity, diabetes, dyslipidemia, chronic alcohol consumption, and medication changes are confounding factors for hepatic dysfunction., Conclusion: Rates of hepatic adverse events (AEs) with bimekizumab were consistent through 2 years; incidences of transaminase elevations were similar to comparators during phase 3/3b controlled study periods., Competing Interests: Conflicts of interest ML: Employee of Mount Sinai and receives research funds from Abbvie, Amgen, Arcutis, Avotres, Boehringer Ingelheim, Cara Therapeutics, Dermavant Sciences, Eli Lilly and Company, Incyte, Inozyme, Janssen Research & Development, LLC, Ortho Dermatologics, Pfizer, Sanofi-Regeneron, and UCB Pharma; consultant for Almirall, AltruBio Inc., AnaptysBio, Apogee, Arcutis Inc., AstraZeneca, Atomwise, Avotres Therapeutics, Brickell Biotech, Boehringer Ingelheim, Bristol Myers Squibb, Castle Biosciences, Celltrion, CorEvitas, Dermavant Sciences, EPI, Evommune Inc., Facilitation of International Dermatology Education, Forte Biosciences, Foundation for Research and Education in Dermatology, Galderma, Genentech, Incyte, LEO Pharma, Meiji Seika Pharma, Mindera, Pfizer, Sanofi-Regeneron, Seanergy, Strata, Takeda, Trevi, and Verrica.

Background: Patients with psoriasis have increased risk of suicidal ideation and behavior (SIB) and depression. Bimekizumab, a biologic that inhibits interleukin (IL)-17A and IL-17F, received Food and Drug Administration approval in 2023 for moderate to severe plaque psoriasis, following 2021 European Medicines Agency approval., Objective: To report SIB and depression in patients with moderate to severe psoriasis treated in bimekizumab clinical trials., Methods: Mental health changes, including neuropsychiatric events, were actively monitored across 9 bimekizumab clinical trials in psoriasis phase 2/3 trials. The patient-reported electronic Columbia-Suicide Severity Rating Scale (measuring SIB) and Patient Health Questionnaire-9 (measuring depression) were administered, monitored by an independent Neuropsychiatric Adjudication Committee., Results: Throughout 7166 patient-years (PY) of bimekizumab exposure, the adjudicated SIB rate was 0.13/100PY; SIB ranges for the general psoriasis population and patients receiving anti-IL-17A/anti-IL-23 therapies are 0.09 to 0.54/100PY and 0.09 to 0.19/100PY, respectively. At week 16, 92.9% vs 81.1% of bimekizumab- vs placebo-treated patients had no/minimal depression. Newonset positive electronic Columbia-Suicide Severity Rating Scale responses and mean Patient Health Questionnaire-9 scores were low for bimekizumab-treated patients., Limitations: Patient exclusion for significant/severe prespecified SIB/depression history., Conclusion: The long-term adjudicated SIB rate with bimekizumab was low and within ranges reported in the general psoriasis patient population and psoriasis patients treated with anti-IL-17A/anti-IL-23 biologics. Screening/monitoring questionnaires reported low SIB and depression levels., Competing Interests: Conflicts of interest All details of authors' affiliation or involvement in an organization or entity with a financial or nonfinancial interest in the subject matter or materials discussed in this manuscript are disclosed.

Background: Patients with psoriasis require long-term management; therefore, understanding the long-term safety of new treatments, such as bimekizumab (BKZ), is crucial., Objectives: To evaluate BKZ's 3-year safety profile in patients with moderate-to-severe plaque psoriasis., Methods: Three years of safety data were pooled from three phase III trials (BE VIVID, BE READY and BE SURE) and their ongoing open-label extension (BE BRIGHT). Treatment-emergent adverse events (TEAEs) are reported using exposure-adjusted incidence rates (EAIRs) per 100 patient-years (PY)., Results: In total, 1495 patients received at least one BKZ dose; total BKZ exposure was 3876.4 PY. The overall EAIR of TEAEs was 175.5/100 PY and decreased with longer exposure to BKZ. The most commonly reported TEAEs were nasopharyngitis, oral candidiasis and upper respiratory tract infection (EAIRs of 15.0/100 PY, 10.1/100 PY and 6.5/100 PY, respectively); 99.3% of oral candidiasis events were mild or moderate in severity, none were serious and few led to discontinuation. EAIRs of other TEAEs of interest were low, including serious infections (1.2/100 PY), adjudicated inflammatory bowel disease (0.2/100 PY) and laboratory elevations in aspartate aminotransferase or alanine aminotransferase (> 5 × upper limit of normal: 0.6/100 PY)., Conclusions: In these analyses pooled across 3 years, no new safety signals were observed with longer exposure to BKZ. The vast majority of oral candidiasis events were mild or moderate in severity, as reported previously., (© The Author(s) 2023.

Importance: Psoriasis is a chronic disease requiring long-term management; understanding the long-term safety profiles of psoriasis treatments, such as bimekizumab, is important., Objective: To evaluate the 2-year safety profile of bimekizumab in patients with moderate to severe plaque psoriasis., Design, Setting, and Participants: Safety data were pooled from a cohort of patients from 4 phase 2 randomized clinical trials (BE ABLE 1, BE ABLE 2, PS0016, and PS0018) and 4 phase 3 randomized clinical trials (BE VIVID, BE READY, BE SURE, and BE BRIGHT) to include 2 years of study treatment. Data were obtained on adults with moderate to severe plaque psoriasis (Psoriasis Area and Severity Index level ≥12, ≥10% body surface area affected by psoriasis, and an Investigator's Global Assessment score ≥3 on a 5-point scale) who were eligible for systemic psoriasis therapy and/or phototherapy., Interventions: Included patients received 1 or more doses of bimekizumab during the phase 2 or phase 3 trials., Main Outcomes and Measures: Treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs leading to treatment discontinuation are reported using exposure-adjusted incidence rates (EAIRs) per 100 person-years., Results: A total of 1789 patients (1252 [70.0%] men; mean [SD] age, 45.2 [13.5] years) were treated with 1 or more doses of bimekizumab across the phase 2/3 trials and were included in these analyses; total bimekizumab exposure was 3109.7 person-years. TEAEs occurred at an EAIR of 202.4 per 100 person-years and did not increase with longer duration of bimekizumab exposure. The 3 most frequently reported TEAEs were nasopharyngitis (19.1 per 100 person-years; 95% CI, 17.4-20.9 per 100 person-years), oral candidiasis (12.6 per 100 person-years; 95% CI, 11.3-14.0 per 100 person-years), and upper respiratory tract infection (8.9 per 100 person-years; 95% CI, 7.8-10.1 per 100 person-years). Most oral candidiasis events were mild or moderate; 3 events led to discontinuation. The EAIRs of inflammatory bowel disease (0.1 per 100 person-years; 95% CI, 0.0-0.3 per 100 person-years), adjudicated suicidal ideation and behavior (0.0 per 100 person-years; 95% CI, 0.0-0.2 per 100 person-years), and adjudicated major adverse cardiac events (0.5 per 100 person-years; 95% CI, 0.3-0.8 per 100 person-years) were low., Conclusions and Relevance: In these pooled analyses of data from a cohort of patients from 8 randomized clinical trials, bimekizumab was well tolerated aside from an increased incidence of mild to moderate oral candidiasis. No safety signals were observed compared with previous reports, and there was no increased risk of AEs with longer duration of bimekizumab exposure.

Background: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A., Objectives: To assess patients' ability to self-inject bimekizumab subcutaneously using a 1 mL safety syringe or auto-injector., Methods: DV0002 and DV0006 were sub-studies of BE BRIGHT, a multicenter, phase 3 open-label extension study. Patients with moderate to severe plaque psoriasis received bimekizumab 320 mg (2x160 mg injections) every 4 or 8 weeks and were randomized 1:1 to the safety syringe or the auto-injector. The ability of patients to safely and effectively self-inject bimekizumab was assessed at 8 weeks (primary endpoint) and immediately after self-injection training at Baseline (secondary endpoint). Patient experience was evaluated using the pain visual analog scale (VAS; 0–100 mm; 100 being worst pain), and the Self-Injection Assessment Questionnaire (SIAQ; 0–10; 10 being most positive experience)., Results: All evaluable patients in DV0002 (n=125) and DV0006 (n=86) safely and effectively self-injected bimekizumab at Week 8. All evaluable patients in DV0002 who used the safety syringe (n=64) and 97.1% (n=66/68) who used the auto-injector, as well as all evaluable DV0006 patients (n=88) also self-injected bimekizumab safely and effectively at Baseline. Median VAS scores were low (range: 7.0–20.0), and median pre-injection and post-injection SIAQ scores were high (range: 5.8–10.0 and 7.1–10.0, respectively) across both devices, sub-studies, and timepoints., Conclusions: Both devices provide a safe and effective option for patients to self-administer bimekizumab. Furthermore, patients reported a positive self-injection experience., Trial Registration: NCT03766685 J Drugs Dermatol. 2022;21(2):162-171. doi:10.36849/JDD.6274THIS ARTICLE HAD BEEN MADE AVAILABLE FREE OF CHARGE.

Introduction: This analysis assessed the psychometric properties of the Psoriasis Symptoms and Impacts Measure (P-SIM), a novel patient-reported outcome (PRO) tool designed to capture patient experiences of the signs, symptoms and impacts of psoriasis., Methods: Blinded data from the BE RADIANT phase 3b trial of bimekizumab were analysed. In BE RADIANT, patients were randomised 1:1 to bimekizumab 320 mg every 4 weeks (Q4W) or secukinumab 300 mg (weekly until Week 4, then Q4W). Three items (itching, skin pain and scaling) of the P-SIM were electronically assessed throughout the trial and were scored from 0 to 10 (none to very severe signs/symptoms/impacts). Test-retest reliability was determined using intraclass correlations. Convergent validity was assessed between P-SIM and other relevant PRO and clinician-reported outcome (ClinRO) scores. Known-groups validity was assessed by comparing mean P-SIM item scores between patient subgroups based on the Psoriasis Area and Severity Index (PASI)/Investigator's Global Assessment (IGA) scores. Responsiveness was assessed via correlations between changes from baseline in P-SIM item scores and other relevant PRO and ClinRO scores. Anchor-based responder analyses and empirical cumulative distribution function (eCDF) curves determined responder thresholds., Results: The three P-SIM items yielded high intraclass coefficients (> 0.70). By Week 48, the three P-SIM items had moderate (> 0.30 and ≤ 0.50) to strong (> 0.50) correlations with other PROs and weaker correlations with ClinROs, demonstrating good convergent validity. For almost all known-group comparisons, statistically significant between-subgroup score differences were seen across all three P-SIM items. Changes from baseline in the P-SIM and other relevant outcomes were above the acceptable threshold of ≤ 0.30, demonstrating sensitivity to change. Anchor-based analyses determined a ≥ four-point reduction from baseline to indicate marked clinically meaningful improvement for the P-SIM., Conclusion: These results support the validity, reliability and sensitivity to change of the P-SIM in assessing key symptoms (itching, skin pain and scaling) in patients with moderate to severe plaque psoriasis., Trial Registration: NCT03536884., (© 2021.

Background: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits both interleukin-17A and interleukin-17F. The efficacy and safety of bimekizumab as compared with secukinumab, which selectively inhibits interleukin-17A alone, in patients with moderate-to-severe plaque psoriasis have not been extensively examined., Methods: In this phase 3b trial, we randomly assigned patients with moderate-to-severe plaque psoriasis, in a 1:1 ratio, to receive bimekizumab subcutaneously at a dose of 320 mg every 4 weeks or secukinumab subcutaneously at a dose of 300 mg weekly to week 4, followed by every 4 weeks to week 48. At week 16, patients receiving bimekizumab underwent rerandomization, in a 1:2 ratio, to receive maintenance dosing every 4 weeks or every 8 weeks to week 48. The primary end point was 100% reduction from baseline in the Psoriasis Area and Severity Index (PASI) score at week 16. The primary analysis was first tested for the noninferiority of bimekizumab to secukinumab at a margin of -10 percentage points and then tested for superiority., Results: A total of 1005 patients were screened and 743 were enrolled; 373 patients were assigned to receive bimekizumab and 370 to receive secukinumab. At week 16, a total of 230 patients (61.7%) in the bimekizumab group and 181 (48.9%) in the secukinumab group had a 100% reduction from baseline in the PASI score (PASI 100) (adjusted risk difference, 12.7 percentage points; 95% confidence interval [CI], 5.8 to 19.6); bimekizumab was shown to be noninferior and superior to secukinumab (P<0.001 for noninferiority and superiority). At week 48, a total of 250 patients (67.0%) treated with bimekizumab had a PASI 100 response, as compared with 171 patients (46.2%) treated with secukinumab (adjusted risk difference, 20.9 percentage points; 95% CI, 14.1 to 27.7; P<0.001). At the week 4 time point, 265 patients (71.0%) in the bimekizumab group had 75% or greater reduction from baseline in the PASI score, as compared with 175 patients (47.3%) in the secukinumab group (adjusted risk difference, 23.7; 95% CI, 17.0 to 30.4; P<0.001). Oral candidiasis occurred more often with bimekizumab (72 patients, 19.3%) than with secukinumab (11 patients, 3.0%)., Conclusions: In patients with moderate-to-severe psoriasis, treatment with bimekizumab resulted in greater skin clearance than treatment with secukinumab over 16 and 48 weeks but was associated with oral candidiasis (predominantly mild or moderate as recorded by the investigator). Longer and larger trials are required to determine the comparative effect and risks of interleukin-17 inhibitors in psoriasis.

Background: Phase 2 psoriasis studies with the Fc-free, PEGylated, anti-tumor necrosis factor biologic certolizumab pegol demonstrated meaningful clinical activity., Objective: Assess safety and efficacy of certolizumab in adults with moderate-to-severe chronic plaque psoriasis., Methods: Patients were randomized 3:3:1:3 to certolizumab 400 mg, certolizumab 200 mg, or placebo every 2 weeks for 16 weeks or etanercept 50 mg twice weekly for 12 weeks. Certolizumab-treated patients achieving a ≥75% reduction in Psoriasis Area and Severity Index (PASI) at week 16 from baseline PASI were rerandomized to certolizumab or placebo for 32 weeks. The primary endpoint was responder rate (≥75% reduction in PASI from baseline PASI) versus placebo (primary analysis) and etanercept (secondary analysis) at week 12; secondary endpoints included responder rates on various measures versus placebo at weeks 12, 16, and 48. Safety was assessed by treatment-emergent adverse events., Results: All endpoints were significantly greater for certolizumab versus placebo with the greatest response seen with 400 mg. Certolizumab 400 mg was superior to and 200 mg was noninferior to etanercept. Adverse events were consistent with the anti-tumor necrosis factor class of drugs., Limitations: Etanercept was administered by unblinded study staff or self-administered, but efficacy assessments were performed by a blinded assessor., Conclusion: Both certolizumab regimens improved psoriasis symptoms, with a greater response seen with the higher dose. No new safety signals were observed., (Copyright © 2018 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.)

Background: Neutralizing interleukin (IL) 17F in addition to IL-17A might provide a more complete and specific approach to inhibiting inflammation., Objective: Assess the efficacy and safety of bimekizumab, a monoclonal antibody that potently and selectively neutralizes IL-17A and IL-17F, in patients with moderate-to-severe plaque psoriasis., Methods: Double-blinded, placebo-controlled phase 2b study (NCT02905006). Patients (randomized 1:1:1:1:1:1) received subcutaneous bimekizumab every 4 weeks at doses of 64 mg, 160 mg, 160 mg with 320 mg loading dose, 320 mg, 480 mg, or placebo. Primary endpoint was ≥90% reduction in Psoriasis Area Severity Index (PASI90) at week 12., Results: There was a significant (P < .0001) dose-dependent response for PASI90 (week 12); more patients achieved PASI90 in the bimekizumab groups (46.2%-79.1%) than patients in the placebo group (0%; P < .0001 all doses). Across all doses, there were significant improvements from baseline for all secondary endpoints (PASI90 week 8, PASI75 week 12, PASI100 week 12, and Investigators Global Assessment clear or almost clear weeks 8 and 12; P ≤ .0003) compared with placebo. More bimekizumab-treated patients than placebo-treated patients achieved PASI100 (week 12) (27.9%-60.0% vs 0%; P ≤ .0002 all doses). Treatment-emergent adverse events were reported by 126 of 208 (61%) bimekizumab-treated patients and 15 of 42 (36%) placebo-treated patients., Limitations: No active comparator., Conclusion: Dual neutralization of IL-17A and IL-17F with bimekizumab provided rapid and substantial clinical improvements in patients with psoriasis, with no unexpected or dose-related safety findings., (Copyright © 2018 American Academy of Dermatology, Inc.

Background: Certolizumab pegol, the only Fc-free, PEGylated anti-tumor necrosis factor biologic, demonstrated clinically meaningful improvements suggestive of a positive risk-benefit balance in phase 2 studies in adults with moderate-to-severe chronic plaque psoriasis., Objective: Assess certolizumab efficacy and safety versus placebo in phase 3 studies., Methods: Patients with moderate-to-severe chronic plaque psoriasis were randomized 2:2:1 to certolizumab 400 mg, certolizumab 200 mg, or placebo every 2 weeks. At week 16, certolizumab-treated patients achieving a 50% reduction in Psoriasis Area and Severity Index continued treatment through week 48. Coprimary endpoints were week 16 responder rates, defined as a 75% reduction in Psoriasis Area and Severity Index and Physician's Global Assessment 0/1 (clear/almost clear) and ≥2-point improvement. Safety was assessed by treatment-emergent adverse events., Results: Week-16 endpoints were significantly greater for both doses of certolizumab versus placebo, and the responses were maintained through week 48. For most measures, improvement was numerically greater for certolizumab 400 mg. No unexpected safety signals were identified., Limitation: There was no active comparator., Conclusion: Treatment with either certolizumab 400 mg or 200 mg every 2 weeks was associated with significant and clinically meaningful improvements in moderate-to-severe psoriasis. The 400-mg dose could provide additional clinical benefit. The safety profile was consistent with the therapeutic class., (Copyright © 2018 American Academy of Dermatology, Inc.

Objective: The product of physician's global assessment and body surface area (PGA×BSA) to assess psoriasis severity has previously been investigated in patients with psoriasis, with the aim of assessing PGA×BSA as an alternative to the time-consuming Psoriasis Area and Severity Index (PASI). Here, we investigate PGA×BSA as an alternative to PASI in patients with psoriatic arthritis (PsA)., Methods: Analyses used data from the double-blind, placebo-controlled, RAPID-PsA trial (NCT01087788) that investigated the efficacy of certolizumab pegol (CZP) in patients with PsA. Outcomes assessed whether the PGA×BSA and PASI results were comparable, and whether these outcomes correlated with one another or with the Dermatology Life Quality Index (DLQI)., Results: For CZP-treated patients, both PGA×BSA and PASI demonstrated similar sensitivities to treatment between baseline and Week 24, with mean improvements of 77.4% and 69.0%, respectively. Similar improvements were also seen with placebo (PGA×BSA: 3.2%, PASI: 6.1%). Achievement of 75% response criterion in PGA×BSA and PASI was attained by similar proportions of patients with CZP (PGA×BSA75: 59.0%, PASI75: 61.4%) and placebo (PGA × BSA75: 15.1%, PASI75: 15.1%). Cross tabulations showed high concordance between achievement of response outcomes in PGA×BSA and PASI (79.6-95.2%). Spearman correlations revealed strong correlations between PGA×BSA and PASI at baseline (r = 0.78; n = 225) and percentage improvement to Week 24 (r = 0.85; n = 186). Both outcomes were only moderately correlated with DLQI (r = 0.41-0.50; n = 179-249)., Conclusion: PGA×BSA is sensitive to changes in skin manifestations in patients with PsA treated with CZP. Further, PGA×BSA correlates strongly with PASI, and achievement of 75% improvement was similar for PGA×BSA and PASI.

Introduction: Plaque psoriasis can significantly impact patients' quality of life. We assessed psychometric properties of the Psoriasis Symptoms and Impacts Measure (P-SIM), developed to capture patients' experiences of signs, symptoms and impacts of psoriasis. Methods: Pooled, blinded, 16-week data from 1002 patients in the BE VIVID and BE READY bimekizumab phase 3 trials were analysed. The suitability of the P-SIM missing score rule (weekly scores considered missing if ≥ 4 daily scores were missing) was assessed. Test–retest reliability was evaluated using intraclass correlation coefficients (ICCs). Convergent validity was assessed between P-SIM and relevant patient-reported outcome (PRO) (Dermatology Life Quality Index [DLQI], DLQI item 1 [skin symptoms], Patient Global Assessment of Psoriasis) and clinician-reported outcome (ClinRO) scores (Psoriasis Area and Severity Index [PASI], Investigator's Global Assessment [IGA]) at baseline and week 16. Known-groups validity was assessed, comparing P-SIM scores between patient subgroups predefined using PASI/IGA scores. Sensitivity to change over 16 weeks was evaluated; responder definition (RD) thresholds were explored. Results: The missing score rule used did not impact P-SIM scores. Test–retest reliability analyses demonstrated excellent score reproducibility (ICC 0.91–0.98). Inter-item correlations at baseline and week 16 were strong (> 0.5), apart from "choice of clothing" with "skin pain" and "burning" at baseline (both 0.49). All P-SIM scores were moderately to strongly correlated with other outcomes, demonstrating convergent validity, apart from ClinROs (PASI, IGA) at baseline that had low variability. P-SIM scores discriminated known groups at week 16, confirming known-groups validity. Changes from baseline to week 16 in P-SIM and other clinically relevant outcomes were strongly correlated (> 0.5; weaker with ClinROs), establishing sensitivity to change. Anchor-based RD analyses determined a four-point P-SIM item score decrease as indicative of marked clinically meaningful improvement. Conclusion: P-SIM scores demonstrated good reliability, validity and sensitivity to change. A four-point RD threshold could be used to assess 16-week treatment effects.

Introduction: Patients with plaque psoriasis experience a variety of signs and symptoms that can impact daily life, which may not be evaluated by clinician-reported outcomes. This study aimed to develop and assess the content validity of a new patient-reported outcome (PRO) measure to capture patient experiences of the signs, symptoms and impacts of psoriasis and aid integration of the patient perspective in treatment benefit-risk decision-making. Methods: The psoriasis symptoms and impacts measure (P-SIM) was developed based on a literature search and interviews with five clinical experts in psoriasis to identify frequent signs, symptoms and impacts of psoriasis. Hybrid concept elicitation, cognitive debriefing and usability testing interviews were conducted with moderate to severe psoriasis patients to evaluate the content validity and patient understanding of the preliminary P-SIM. The preliminary P-SIM was refined using initial quantitative analyses of phase 2b data from psoriasis patients to inform the removal of any items. Results: A preliminary 19-item P-SIM was developed for administration on a hand-held electronic tablet device using a 0–10 numerical response scale over a 24-h recall period. Patient interviews and testing demonstrated most patients interpreted the items and responses as intended, would not re-word any items, felt the responses matched the items and rated the device as easy to use. After quantitative testing, five items were removed from the preliminary 19-item measure because of conceptual overlap, floor effects and/or skewed distributions to generate the final 14-item P-SIM. Conclusions: The P-SIM questionnaire has good content validity; patients reported it was easy to understand and reflective of their experiences. Following psychometric validation, the P-SIM may be a useful PRO measure for capturing the signs, symptoms and impacts of psoriasis and may support clinician-reported outcomes when assessing treatment benefits in clinical trials.
