Mean Change From Baseline Research Articles

Health-related quality of life (HRQoL), functioning, and symptoms with odronextamab monotherapy in patients (pts) with relapsed or refractory follicular lymphoma (R/R FL) by POD24 status in the ELM-2 study.

e19057 Background: In ELM-2 (NCT03888105), a Ph 2, single arm, open label trial, odronextamab demonstrated robust efficacy, generally manageable safety, and overall maintenance of patient-reported outcomes (PROs) in R/R FL pts (Villasboas et al. ASH 2023). In FL, pts with disease progression within 2 yrs of frontline chemoimmunotherapy (POD24) are hard to treat with poor clinical outcomes, representing an unmet need. We report PROs by POD24 status in pts with Grade 1–3a R/R FL from ELM-2. Methods: Pts received IV odronextamab in 21-day cycles (C): 80 mg QW in C1–4, with C1 dose step up to mitigate cytokine release syndrome, then 160 mg Q2W (Q4W if complete response ≥9 mo) until progression. PROs were collected at baseline (BL), Wks 2–4, 10, then Q8W in Yr 1, and Q12W in Yr 2. Post-hoc POD24 subgroup analyses were performed on six EORTC QLQ-C30 scales, the EQ-5D-3L VAS, and FACT-Lym LymS. Estimated mean change from BL (CFB) was analyzed using mixed models for repeated measures (MMRM) through Wk 42 (≥10 pts at last assessment). Published meaningful CFB thresholds were used to define deterioration/improvement in responder analyses. Results: By Jan 31, 2023, 140 pts with R/R FL had received odronextamab. Pts with POD24 (n=70) were younger than pts without POD24 (n=70; median age 57.5 vs 62.0 y), had fewer prior Tx lines (median 2 vs 3), and a higher proportion double refractory to anti-CD20 Ab + alkylator (53% vs 29%). Objective response rate was similar in evaluable pts with (n=63; 79%) and without (n=65; 80%) POD24. PRO questionnaire completion ranged from 52–95% through Wk 42 across groups. Descriptive analyses suggest BL PRO scores were similar by POD24 status, showing good HRQoL/functioning and low symptom burden, and were generally maintained through Wk 42 with minimal between-group differences (overlapping 95% CIs for LS mean CFB [Table]). In both groups, more pts reported PRO maintenance or improvement vs deterioration across visits, except for fatigue at Wk 10 in pts without POD24. Conclusions: In pts with heavily pretreated R/R FL, odronextamab Tx maintained HRQoL, functioning, and symptoms irrespective of POD24 status. Clinical trial information: NCT03888105 .

Phase I DAVIO Trial: EYP-1901 Bioerodible, Sustained-Delivery Vorolanib Insert in Patients With Wet Age-Related Macular Degeneration

PurposeTo evaluate safety and tolerability of EYP-1901, an intravitreal insert containing vorolanib, a pan–vascular endothelial growth factor (VEGF) receptor inhibitor packaged in a bioerodible delivery technology (Durasert E™) for sustained delivery, in patients with wet age-related macular degeneration (wAMD) previously treated with anti-VEGF therapy. DesignPhase 1, multicenter, prospective, open-label, dose-escalation trial. ParticipantsPatients with wAMD and evidence of prior anti-VEGF therapy response. MethodsPatients received a single intravitreal injection of EYP-1901. Main Outcome MeasuresThe primary objective was to evaluate safety and tolerability of EYP-1901. Secondary objectives assessed biologic activity of EYP-1901 including best-corrected visual acuity (BCVA) and central subfield thickness (CST). Exploratory analyses included reduction in anti-VEGF treatment burden and supplemental injection-free rates. ResultsSeventeen patients enrolled in the 440 μg (3 patients), 1030 μg (1 patient), 2060 μg (8 patients), and 3090 μg (5 patients) dose cohorts. No dose-limiting toxicity, ocular serious adverse events (AEs), or systemic AEs related to EYP-1901 were observed. There was no evidence of ocular or systemic toxicity related to vorolanib or the delivery technology. Moderate ocular treatment-emergent AEs (TEAEs) included reduced visual acuity (2/17) and retinal exudates (3/17). One patient with reduced BCVA had 3 separate reductions of 17, 18, and 16 letters, and another had a single drop of 25 letters. One severe TEAE, neovascular AMD (i.e., worsening/progressive disease activity), was reported in 1 of 17 study eyes but deemed unrelated to treatment. Mean change from baseline (CFB) in BCVA was –3.7 letters and –5.4 letters at 6 and 12 months. Mean CFB in CST was +1.7 μm and +2.3 μm at 6 and 12 months. Reduction in treatment burden was 76% and 72% at 6 and 12 months. Of 16 study eyes, 13, 9, and 6 were injection-free up to 3, 6, and 12 months. ConclusionIn the DAVIO trial (ClinicalTrials.gov identifier, NCT04747197), EYP-1901 had a favorable safety profile and was well tolerated in previously treated eyes with wAMD. Measures of biologic activity remained relatively stable following a single EYP-1901 injection. These preliminary data support ongoing Phase 2 and planned Phase 3 trials to assess efficacy and safety.

INDIVIDUAL ARTICLE: Sarecycline Improves Acne Severity, Symptoms, and Psychosocial Burden in Non-nodular Acne Vulgaris: PROSES Study.

Patient-reported outcomes (PROs) are emerging as a fundamental component of disease impact assessment in acne vulgaris (AV), complementing clinician-reported outcomes. No data is available on PROs for patients with AV using sarecycline in real-world settings. A single-arm, prospective cohort study that included patients ≥9 years old diagnosed with moderate or severe non-nodular AV was implemented as part of routine care in clinical practices (N=30). Patients received oral sarecycline (60 mg, 100 mg, or 150 mg) for 12 weeks, as part of usual care. The primary endpoint was Acne Symptom and Impact Scale (ASIS) responses from patients (≥12 years) and caregivers (for patients 9-11 years) at week 12 and change from baseline (CFB). Investigator’s Global Assessment (IGA) of AV severity and adverse events (AEs) were also recorded. A total of 253 patients with AV completed the study (adults: 60.1%, females: 77.6%). ASIS mean scores significantly decreased (P <.0001) at week 12 for: signs (mean CFB ± standard deviation [SD]: –0.8 ± 0.7), impact (–1.0 ± 1.0), emotional impact (–1.2 ± 1.1), and social impact (0.6 ± 1.1). Significant reductions in AV severity (P <.0001) were reported by patients and caregivers. The IGA success rate was 58.9% and physician satisfaction with treatment outcomes was 88.1%. A total of 31 (10.3%) patients reported ≥1 AE during the study. Patients with moderate-to-severe AV receiving acne management with an oral antibiotic for 12 weeks experienced a significant improvement in AV-related symptoms and psychosocial burden.

Maintenance of zilucoplan efficacy in patients with generalised myasthenia gravis up to 24 weeks: a model-informed analysis.

Clinical efficacy of zilucoplan has been demonstrated in a 12-week, placebo-controlled, phase III study in patients with acetylcholine receptor autoantibody-positive generalised myasthenia gravis (gMG). However, placebo-controlled zilucoplan data past 12 weeks are not available. Predict the treatment effect of zilucoplan versus control (placebo or standard of care) in patients with gMG up to 24 weeks. A model-informed analysis (MIA) within a Bayesian framework. Part 1 of the MIA comprised a control meta-regression using aggregate data on control response over time from randomised studies and a national myasthenia gravis (MG) registry. In Part 2, a combined Bayesian analysis of individual patient-level data from the phase II (NCT03315130), RAISE (NCT04115293) and RAISE-XT (NCT04225871) studies of zilucoplan was conducted using posterior distributions from Part 1 as informative priors. Population mean treatment effect in the change from baseline (CFB) at week 24 in MG-Activities of Daily Living (MG-ADL) and quantitative MG (QMG) scores for zilucoplan versus control were assessed. At week 24, the predicted mean CFB in MG-ADL score was -4.55 (95% credible interval: -6.04, -3.13) with zilucoplan versus -2.00 (-3.35, -0.64) with control (difference: -2.55 [-3.76, -1.40]). The probability of a favourable treatment effect as measured by MG-ADL score at week 24 with zilucoplan versus control was >99.9%. There was an 82.8% probability that the difference in the predicted mean CFB in MG-ADL score at week 24 was greater than the clinically meaningful threshold (⩾2.0-point improvement). Comparable results were observed with QMG. This MIA demonstrates the maintenance of efficacy with zilucoplan versus control up to 24 weeks. Through combining real-world evidence with data from randomised studies, this novel method to estimate long-term treatment efficacy facilitated reduced exposure to placebo in the phase III RAISE study. This methodology could be used to reduce the length of future placebo-controlled studies.

Efficacy and Safety of PF-07038124 in Patients With Atopic Dermatitis and Plaque Psoriasis

Atopic dermatitis (AD) and plaque psoriasis are inflammatory skin diseases with unmet need for effective topical treatments with few application site reactions. To assess the efficacy and safety of the topical phosphodiesterase 4 inhibitor PF-07038124 in patients with AD and plaque psoriasis. This phase 2a, randomized, double-blind clinical trial was conducted from December 21, 2020, to August 18, 2021, at 34 sites across 4 countries. Eligible patients (aged 18-70 years) had mild to moderate AD (covering 5%-20% body surface area) or plaque psoriasis (covering 5%-15% body surface area). Data were analyzed until December 15, 2021. Patients were randomized (1:1) to PF-07038124, 0.01%, topical ointment or vehicle once daily for 6 weeks. The primary end point was the percent change from baseline (CFB) in the Eczema Area and Severity Index (EASI) total score among patients with AD and in the Psoriasis Area and Severity Index (PASI) score among patients with plaque psoriasis at week 6. Safety measures included treatment-emergent adverse events, including application site reactions. Overall, 104 patients were randomized (mean [SD] age, 43.0 [15.4] years; 55 [52.9%] women; 4 [3.8%] Asian, 13 [12.5%] Black, and 87 [83.7%] White), including 70 with AD (41 women [58.6%]; mean [SD] ages, 41.4 [16.6] years in the PF-07038124 group and 36.1 [13.9] years in the vehicle group) and 34 with plaque psoriasis (20 men [58.8%]; mean [SD] ages, 51.8 [12.3] years in the PF-07038124 group and 51.2 [10.8] years in the vehicle group). Baseline characteristics were generally balanced. At week 6, the PF-07038124 groups showed significantly greater improvements compared with vehicle groups in EASI (least-squares mean CFB, -74.9% vs -35.5%; difference, -39.4% [90% CI, -58.8% to -20.1%]; P < .001) and PASI scores (CFB, -4.8 vs 0.1; difference, -4.9 [90% CI, -7.0 to -2.8]; P < .001). The number of patients with treatment-emergent adverse events was comparable between treatment groups in patients with AD (PF-07038124, 9 [25.0%]; vehicle, 9 [26.5%]) and plaque psoriasis (PF-07038124, 3 [17.6%]; vehicle, 6 [35.3%]). There were no application site reactions with PF-07038124 treatment. Topical PF-07038124 was well tolerated and demonstrated superior efficacy compared with vehicle in patients with mild to moderate AD and plaque psoriasis. ClinicalTrials.gov Identifier: NCT04664153.

Effectiveness of Valsartan's Single-Pill Combination Therapies on Blood Pressure Control in Hypertensive Patients: Malaysian Single-Centre Real-World Experience.

Uncontrolled hypertension can cause cardiovascular disease and is an important public health issue. Single-pill combination (SPC) therapies possess combined blood pressure (BP)-lowering effect and may improve compliance to treatment. This study assessed the effectiveness of valsartan (Val)-based SPC therapies in achieving BP control in hypertensive patients. This was a retrospective study. Data were extracted from the hybrid medical records of patients from the Institut Jantung Negara (IJN), Malaysia. Adults with established diagnosis of hypertension and on prescription of Val-based SPC therapies as part of routine medical care from 1 January 2013 to 31 December 2018, with ≥ 1 year of follow-up were included. Primary endpoint was proportion of patients achieving therapeutic BP control (BP < 140/90 mmHg). Secondary outcomes included change from baseline (CFB) in systolic BP (SBP) and diastolic BP (DBP), and subgroup analysis was based on baseline SBP categories and presence of diabetes. Study included 409 hypertensive patients. The mean (standard deviation [SD]) age of the population was 65.1 (10.6) years old, with male predominance (61.6%). Proportion of patients achieving target BP between baseline and follow-up were 57.0% (P < 0.001). Mean CFB in SBP and DBP were recorded as 19.52 mmHg and 7.47 mmHg, respectively. Over half of the patients achieved the target BP in all subgroups categorised by SBP at baseline, except the subgroup of SBP 160 mmHg-179 mmHg. SPC therapies were continued in 97.3% of patients at 1-year follow-up. Patients using Val-based SPC therapies had significant reduction in BP with good tolerability, with 57% of patients achieving target BP over a prolonged 1-year follow-up period. Uptake of SPC therapy is warranted to improve patient care and outcomes in hypertension.

O-027 Efficacy results from a phase 3, randomized, placebo-controlled trial testing two doses of linzagolix in women with endometriosis-associated pain

Abstract Study question Does once-daily linzagolix for up to 6 months reduce the pain symptoms in women with endometriosis? Summary answer Once-daily oral use of the GnRH agonist linzagolix alone or in combination with combined hormonal add-back therapy (ABT) for 24 weeks improved endometriosis-associated pain symptoms. What is known already Linzagolix is an oral GnRH antagonist under development to treat endometriosis-associated pain (EAP). In the EDELWEISS 3 study linzagolix 200mg+ABT met its co-primary endpoints at 3 months by reducing dysmenorrhea (DYS) and non-menstrual pelvic pain (NMPP) in a clinically meaningful fashion along with a stable or decreased use of analgesics. Linzagolix 75mg significantly reduced DYS but not NMPP. Secondary endpoints were DYS, NMPP, overall pelvic pain, dyschezia, and dyspareunia at 6 months assessed with a numeric and/or verbal rating scale (NRS and/or VRS), and interference of pain with daily activities assessed with the Endometriosis-Health-Profile-30 (EHP-30) pain domain. Study design, size, duration EDELWEISS 3 was a randomized, double-blind, placebo-controlled Phase 3 study, investigating efficacy and safety of linzagolix 75mg and linzagolix 200mg with ABT (1mg estradiol/0.5mg norethindrone acetate) for up to 24 weeks in women with moderate to severe EAP. To qualify, subject had to demonstrate over 2 menstrual cycles at least moderate DYS and NMPP for ≥2 days each and at least moderate overall pelvic pain for ≥5 days. Participants/materials, setting, methods Eligible women with moderate to severe EAP were equally randomized to once daily oral: placebo, linzagolix 75mg or linzagolix 200mg+ABT. Efficacy assessments included DYS, NMPP, dyspareunia (assessed with a 4-point VRS), overall pelvic pain and dyschezia (assessed with an 11-point NRS), and interference of pain with daily activities (assessed with the EHP-30 pain domain). The co-primary endpoint was a responder analysis at Month 3. We present secondary endpoints at Month 6. Main results and the role of chance Participants (n = 484) had a mean age of 35 years, a BMI of 24kg/m2 with 99% of subjects being White. At Month 6, compared to placebo significant improvements in DYS and NMPP (VRS) were observed in the 200mg+ABT group, with an estimated mean change from baseline (CfB) of -1.83 (95%CI: 1.96, 1.70; difference with placebo p &amp;lt; 0.001) and 0.92 (95%CI: 1.03, 0.82; p = 0.002), respectively. For the 75mg group, the mean CfB was 1.10 (95%CI: 1.23; 0.97; p &amp;lt; 0.001) and 0.84 (95%CI: 0.95; 0.73; p = 0.048), respectively. For overall pelvic pain (NRS), marked improvements were observed with an estimated mean CfB of 3.39 (95%CI: 3.74, 3.03; p &amp;lt; 0.001) for 200mg+ABT and 2.84 (95%CI: 3.20, 2.48; p = 0.024) for 75mg. Similarly, dyschezia (NRS) was significantly improved for both groups with a mean CfB of 1.99 (95%CI: 2.29, 1.70; p = 0.012) for 200mg+ABT and -1.98 (95%CI: 2.28, 1.69; p = 0.015) for 75mg. Both doses offered a marked, statistically significant improvement in the interference of pain with daily activities as measured on the EHP-30 Pain Dimension, with an estimated mean CfB of 35.60 (95%CI: 38.73, 32.48; p &amp;lt; 0.001) and -27.37 (95%CI: 30.50, 24.25; p = 0.001) for the 200mg+ABT and 75mg group, respectively. Both doses did not provide significant improvements in dyspareunia. Limitations, reasons for caution We report data of the EDELWEISS 3 study for up to Month 6. An extension study of this trial will provide more information on the sustained effect and potential symptom recurrence after stopping treatment. Wider implications of the findings The linzagolix 200mg+ABT group provided substantial improvement in endometriosis-associated pain symptoms. The 75mg dose was less effective but demonstrated still marked improvements. There exists an substantial need for different treatment regimens in women suffering from endometriosis. Trial registration number NCT03992846

P118 Baseline Characteristics of and Early Outcomes in the First 200 Patients With Rheumatoid arthritis Treated With Filgotinib in a Prospective Observational Study

Abstract Background/Aims Filgotinib (FIL) is a preferential Janus kinase 1 inhibitor, approved in Europe for the treatment of Rheumatoid arthritis (RA). A phase 4 European study of FIL (FILOSOPHY; NCT04871919) in patients with RA is ongoing. We report baseline characteristics and 1-month efficacy data from the first 200 patients. Methods The prospective, observational study will enroll approximately 1500 patients aged ≥18 years with moderate-severe active RA, prescribed FIL for the first time in accordance with the product label. We report baseline demographics, disease characteristics, comorbidities, prior treatments, reasons for starting FIL, and mean change from baseline (CFB) in pain severity (measured using a 10-cm visual analog scale [VAS]) and Functional Assessment of Chronic Illness Therapy (FACIT)-fatigue score (range 0-52) via electronic PRO data collection at Week 1 and Month 1, and mean CFB in Clinical Disease Activity Index (CDAI; range 0-76) score at Month 1. The proportion of patients with clinically meaningful CFB in FACIT-fatigue (increase of ≥ 4) and VAS pain (reduction of ≥ 10) from Week 1 to Month 1 was reported. Patients included in analysis were enrolled May 2021-February 2022. Results 206 patients were enrolled from Germany (n = 134), UK (n = 40), Netherlands (n = 27), Belgium (n = 4), and Italy (n = 1); nearly 75% were female, mean (standard deviation [SD]) age 56.8 (10.6) years, and mean (SD) RA duration 10.0 (9.5) years. Approximately 40% of treated patients had comorbidities, most common: hypertension (28.3%), dyslipidemia (9.1%), type 2 diabetes mellitus (5.3%). FIL was started due to inadequate response (43.3%), loss of response (40.6%), or intolerance (non-allergic) to previous treatment (5.9%), or for other reasons (10.2%). Of treated patients, 167 (89.3%) received FIL 200 mg and 20 (10.7%) received FIL 100 mg (study drug information was pending for 19 patients). FIL monotherapy was taken by 55.6% of patients (19.3% with glucocorticoids), while 37.4% received FIL in combination with MTX (13.4% with glucocorticoids). Mean (SD) and median (range) daily dose of oral glucocorticoids at baseline was 7.5 (6.0) mg and 5.0 (1.0-30.0) mg. At Week 1 and Month 1, respectively, mean (SD) CFB in FACIT-fatigue score was 3.7 (6.9) and 6.8 (8.6), and mean (SD) CFB in VAS pain score was -11.9 (18.0) and -22.2 (27.8). At Month 1, mean (SD) CFB in CDAI score was -13.7 (17.1). Conclusion These are the first international real-world data to be reported from a cohort of RA patients treated with FIL. At baseline, patients generally had moderate disease activity. Initial interim data indicate rapid improvements in disease measures with FIL treatment (given as combination therapy or monotherapy, with/without glucocorticoids), which could be observed as early as Week 1 for VAS pain and FACIT-fatigue scores. Long-term follow-up is needed to further evaluate effectiveness and safety. Disclosure J.

Improvement in Depression Symptoms Measured by Montgomery-Åsberg Depression Rating Scale and Quick Inventory of Depressive Symptomatology-Self Rated Items after Randomised Double-blind COMP360 Psilocybin Therapy for Treatment-resistant Depression

IntroductionCOMP360 is a synthetic, proprietary, purified form of psilocybin in development for treatment-resistant depression (TRD) with FDA Breakthrough Therapy designation. In a recent phase IIb study, COMP360 psilocybin 25mg was superior to 1mg on change from baseline (CFB) to Week 3 on the Montgomery-Åsberg Depression Rating Scale (MADRS) total score (primary efficacy endpoint), when administered alongside psychological support. Quick Inventory of Depressive Symptomatology-Self Rated (QIDS-SR 16) total score (exploratory efficacy endpoint) showed similar results.ObjectivesTo analyse changes in specific depression symptoms after psilocybin treatment in the aforementioned study, as measured by individual item scores on the MADRS and QIDS-SR 16 (range 0-6 and 0-3).MethodsParticipants with TRD were randomised to single doses of psilocybin 25mg (n=79), 10mg (n=75), or 1mg (n=79). A remote, blinded rater assessed the MADRS at Baseline, Day 2 (the day post-psilocybin), and Weeks 1, 3, 6, 9, and 12. The QIDS-SR 16 was self-rated at Baseline, Day 1, Day 2, and Weeks 1, 2, 3, 6, 9, and 12. At each time point, descriptive statistics were calculated for each MADRS and QIDS-SR 16 individual item score.ResultsAt Week 3, MADRS items with the largest differences in mean CFB in the 25mg arm were Inability to Feel, Apparent Sadness, Lassitude, and Reported Sadness. Greater improvement in the 25mg arm was apparent from Day 2 and remained to Week 12 (Lassitude remained to Week 6 only). On the QIDS-SR 16, the item with the largest difference in mean CFB at Week 3 in the 25mg arm was in Feeling Sad and remained evident to Week 12 (Table 1).Table 1.Item (mean CFB at Week 3 [standard deviation])Psilocybin 25mgPsilocybin 10mgPsilocybin 1mgMADRS - Inability to Feel-1.8 [1.81]-0.9 [1.54]-0.8 [1.61]MADRS - Apparent Sadness-1.7 [1.94]-1.1 [1.60]-0.9 [1.62]MADRS - Lassitude-1.6 [1.81]-1.2 [1.83]-0.8 [1.58]MADRS - Reported Sadness-1.6 [1.95]-1.0 [1.52]-0.6 [1.53]QIDS-SR16- Feeling Sad-1.1 [1.08]-0.8 [1.07]-0.4 [0.91]ConclusionsA single administration of COMP360 psilocybin therapy rapidly and dose-relatedly improved symptoms of depressed mood and anhedonia – the two key symptoms of depression. As anhedonia is predictive of poorer treatment response, and improvements in anhedonia correlate with improvements in functioning, it is important to understand the impact of treatments on this symptom.Disclosure of InterestG.

Active Study: Impact of Voxelotor on Sleep Quality, Physical Activity, and Patient-Reported Outcomes

Background: Sickle cell disease (SCD) is an inherited disorder in which sickle hemoglobin (HbS) polymerization causes red blood cell sickling, resulting in complications such as chronic hemolytic anemia, vaso-occlusion, end-organ damage, and decreased quality of life. Voxelotor is a first-in-class HbS polymerization inhibitor approved in the US for the treatment of SCD in patients aged ≥4 years. The pivotal phase 3 HOPE and phase 2a HOPE-KIDS 1 trials demonstrated the safety and efficacy of voxelotor in increasing hemoglobin (Hb) and decreasing hemolytic markers. Objective: Here we report Hb response, patient-reported quality-of-life (QOL) outcomes, and safety data from the ongoing ActIVe study (NCT04400487), a phase 4, multicenter, open-label study evaluating the effect of voxelotor on physical activity, sleep quality, and overall well-being in patients with SCD. Methods: Patients aged 12 to 55 years with SCD received voxelotor 1500 mg/day for up to 24 weeks across 10 US sites. QOL assessments were completed during baseline (BL) run-in before the start of voxelotor. Hb levels were measured via laboratory assessments at BL and at weeks 2, 12, and 24. The proportion of patients with any increase in Hb from BL was noted. Patient-reported outcomes were evaluated using the Patient Global Impression of Change (PGI-C) scale, the National Institutes of Health Patient-Reported Outcome Measurement Information System-43 (PROMIS-43) for adults (>17 years), PROMIS-37 for adolescents (≤17 years), and a 10-point numeric rating scale (NRS) for pain intensity. A minimum response deemed meaningful was interpreted at the group level as a ≥5-point change from BL (CFB) in PROMIS domains and a ≥2-point change on the NRS. Clinicians' perceptions of the impacts of voxelotor on patients' overall health status were captured using the Clinical Global Impression of Change (CGI-C). All treatment-emergent adverse events (TEAEs) were recorded from the time of consent/assent to 28 days after the last dose of voxelotor. Results: A total of 25 patients were enrolled, with a median (range) age of 20.0 (12-51) years; 64.0% of patients were female and 92.0% were Black or African American. Two (8.0%) patients permanently discontinued voxelotor due to non-compliance and loss to follow-up. A total of 14 of 18 (78%) patients had an increase in Hb at week 24; the mean (SD) increase was 0.53 (0.839) g/dL. Clinicians reported an improvement in health status among 84.6% (11/13) of patients at week 24: 7.7% (1/13) were "very much improved," 46.2% (6/13) were "much improved," and 30.8% (4/13) were minimally improved; 2 patients had no change. At week 24, 92.9% (13/14) of patients self-reported improved health status: 21.4% (3/14) were "very much improved," 42.9% (6/14) were "much improved," and 28.6% (4/14) were minimally improved; 1 patient reported minimally worse health status. At week 24, 14 patients (9 adults, 5 adolescents) completed PROMIS measures; improvements in the mean CFB were reported across several PROMIS health domains. In adults, a meaningful CFB was found for both fatigue and pain interference. Some domains reached near-meaningful improvements, including anxiety, sleep disturbance, and ability to participate (in social roles/other activities), and others improved more modestly (Table 1). While some domains improved among adolescents, none reached a meaningful level (Table 2). A total of 18 (72.0%) patients had ≥1 non-SCD-related TEAE, and 3 (12.0%) patients had ≥1 grade 3 non-SCD-related TEAE. No non-SCD TEAEs of grade 4 or higher were reported. The most common non-SCD-related TEAEs (>10%) were diarrhea (32.0%), headache (20.0%), nausea (20.0%), and vomiting (12.0%). Conclusions: Over three-quarters of voxelotor-treated patients achieved an increase in Hb at week 24, and most patients and clinicians reported improvement in patients' overall health status. The PROMIS data in voxelotor-treated adults provided insights into improvements in general well-being, such as fatigue, pain interference, and ability to participate; most notable were fatigue and pain interference, both of which reached a CFB threshold considered meaningful. The safety profile reported in ActIVe is consistent with previous studies of voxelotor treatment. Overall, results suggest that voxelotor-treated patients may experience improvements in QOL, including in their physical and emotional well-being. Funding: Global Blood Therapeutics.

217O Patient-reported outcomes (PROs) from DESTINY-Breast04, a randomized phase III study of trastuzumab deruxtecan (T-DXd) vs treatment of physician's choice (TPC) in patients (pts) with HER2-low metastatic breast cancer (MBC)

DESTINY-Breast04 (NCT03734029) showed improvement in progression-free and overall survival of T-DXd vs TPC in pts with HER2-low MBC regardless of hormone receptor status, with no new safety signals. Here we report PROs on the effect of treatment on health-related quality of life (QOL) of T-DXd vs TPC in the hormone receptor–positive cohort. Pts with centrally confirmed HER2-low (IHC1+ or IHC2+/ISH-) MBC with 1-2 prior lines of chemotherapy in the metastatic setting were assigned 2:1 to T-DXd (Q3W) or TPC (Q3W or Q4W). PROs were measured using the European Organization for Research and Treatment of Cancer QOL questionnaires (EORTC QLQ-C30, primary variable: global health status [GHS]/QOL scale score, and EORTC QLQ-BR23) and the EuroQol 5-dimension, 5-level (EQ-5D-5L) visual analog scale (VAS). PROs were assessed at prespecified timepoints per the protocol. Change from baseline (CFB) and time to definitive deterioration (TDD) were assessed. Deterioration was defined as an increase of ≥10 points. In both arms, compliance for questionnaires was >92% at baseline and >80% for cycles 2-27. Baseline GHS score was 36.3 for T-DXd and 37.8 for TPC. Mean CFB for GHS/QOL of the QLQ-C30 remained stable (within ± 10 points) over time for pts in the T-DXd arm (n=331) up to 27 cycles and TPC arm (n=163) up to 13 cycles; beyond these cycles, the number of pts on treatment (n<10%) was too low to be informative. Median TDD of QLQ-C30 GHS/QOL was 7.6 mo for T-DXd vs 5.1 mo for TPC (hazard ratio [HR], 0.71 [95% CI, 0.56-0.92]), and all prespecified QLQ-C30 subscales had longer TDD with T-DXd, including pain (HR, 0.51 [95% CI, 0.39-0.65]) and physical functioning (HR, 0.54 [95% CI, 0.42-0.70]). For breast-specific arm symptoms of the QLQ-BR23, median TDD was 9.8 mo for T-DXd vs 5.4 mo for TPC (HR, 0.67 [95% CI, 0.50-0.88]). Median TDD of EQ-5D-5L VAS was 8.8 mo for T-DXd vs 4.7 mo for TPC (HR, 0.70 [0.54-0.91]). Pts who received T-DXd maintained GHS/QOL longer than TPC in all prespecified QLQ-C30 subscales while on therapy. These results are consistent with the primary results and confirm the QOL benefit of T-DXd vs TPC for pts with HER2-low MBC.

Effect of transcutaneous auricular vagus nerve stimulation on major depressive disorder with peripartum onset: A multicenter, open-label, controlled proof-of-concept clinical trial (DELOS-1)

BackgroundPostpartum depression has a high prevalence in the United States (~13 %) and often goes undertreated/untreated. We conducted a multicenter, open-label, proof-of-concept trial to assess the Nēsos wearable, non-invasive, transcutaneous auricular vagus nerve stimulation (taVNS) system for the treatment of major depressive disorder with peripartum onset (PPD). MethodsWomen (n = 25), ages 18 to 45, within 9 months postpartum, and diagnosed with PPD were enrolled at 3 sites. The study included 6 weeks open-label therapy and 2 weeks observation. Efficacy outcomes included change from baseline (CFB) in Hamilton Rating Scale for Depression (HAMD17) total scores, HAM-D17 response and remission, and patient and clinician global impression of change (PGIC, CGIC) scores. Analysis included descriptive statistics and mixed-effects models for repeated measures. ResultsThe most common AEs (≥5 %) were discomfort (n = 5), headache (n = 3), and dizziness (n = 2); all resolved without intervention. No serious AEs or deaths occurred. Baseline mean HAM-D17 score was 18.4. Week 6 least squares (LS) mean CFB in HAM-D17 score was −9.7; 74 % achieved response and 61 % achieved remission. At week 6, at least some improvement was reported by 21 of 22 (95 %) clinicians on CGIC and 22 of 23 (96 %) participants on PGIC. LimitationsThis was a single-arm, open-label study, and enrollment was limited to participants with mild-to-moderate peripartum depression. ConclusionResults from this proof-of-concept study suggest that the Nēsos taVNS system is well tolerated and may be an effective non-invasive, non-pharmacological treatment for major depressive disorder with peripartum onset. Further evaluation in larger sham-controlled studies is needed. ClinicalTrials.govNCT03972995

O-306 LINZAGOLIX FOR ENDOMETRIOSIS-ASSOCIATED PAIN: SAFETY RESULTS FROM EDELWEISS 3, A PHASE 3, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED TRIAL

Abstract Study question Is once-daily linzagolix treatment for women with moderate to severe endometriosis-associated pain (EAP) safe for use for up to 6 months of treatment? Summary answer Both doses of linzagolix were well-tolerated with minimal BMD decrease and few TEAEs &amp;gt;5% in either linzagolix arm. What is known already Linzagolix (LGX) is an investigational once-daily oral GnRH receptor antagonist that reduces serum estradiol in a dose-dependent manner and is being developed in two dosages for the treatment of endometriosis-associated pain (EAP): 75 mg, and 200 mg dose with hormonal add-back therapy (ABT). Study design, size, duration EDELWEISS 3 is a randomized, double-blind, placebo-controlled, multicenter Phase 3 trial of linzagolix in women with moderate to severe EAP. The trial includes 3 treatment arms: 75 mg LGX, 200 mg LGX with ABT (E2 1 mg/ NETA 0.5 mg), or placebo. Here we present safety results up to 6 months (24 weeks) of treatment. Participants/materials, setting, methods Eligible reproductive-aged women with moderate-to-severe EAP were randomized and treated (n = 484) for 6 months with 75 mg LGX, 200 mg LGX with ABT (E2 1 mg/ NETA 0.5 mg), or placebo. Safety and tolerability objectives reported here include 6-month results for treatment emergent adverse events (TEAEs), assessment of mean percent change from baseline (CfB) in lumbar spine (LS) bone mineral density (BMD) and Z-scores. The safety analysis set included 484 subjects across the 3 treatment groups. Main results and the role of chance The overall incidence of TEAEs was similar between the placebo and LGX 75 mg group (46.9%) and slightly higher (56.8%) in the LGX 200 mg + ABT group. There were few (3) serious TEAEs, and none were related to LGX. TEAEs that occurred in over 5% of patients in either active treatment arm included headache (10.5%, 8.1%, and 8.0%), hot flush (6.8%, 7.5%, and 2.5%), and fatigue (6.8%, 3.8%, and 2.5%) for the 200 mg LGX with ABT, 75 mg LGX, and placebo groups, respectively. Mean percent CfB (95% CI) in LS BMD was -0.79% (-1.15, -0.43%), -0.89% (-1.31, -0.47%), and +0.78% (0.41, 1.15%) for the 200 mg LGX with ABT, 75 mg LGX, and placebo groups, respectively. Z-scores at 6 months remained within the same range as baseline in all groups. Limitations, reasons for caution Additional efficacy and safety results from the trial's 24 weeks (6 mo) extension phase are pending. (Edelweiss 6 protocol: NCT04335591) Wider implications of the findings These results support further development of ABT and non-ABT doses of linzagolix that have potential to provide flexibility and choice for women seeking treatment for EAP. A non-ABT option is important for women who have a contraindication to, are at increased risk for complications, or prefer not to use ABT. Trial registration number ClinicalTrials.gov: NCT02778399

Efficacy and Safety of Pegcetacoplan Treatment in Complement-Inhibitor Naïve Patients with Paroxysmal Nocturnal Hemoglobinuria: Results from the Phase 3 Prince Study

Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare and life-threatening disease characterized by hemolysis and thrombosis. Many patients with PNH use C5-inhibitors (i.e., eculizumab/ravulizumab) to control their symptoms. Although C5-inhibition prevents intravascular hemolysis (IVH), it fails to prevent extravascular hemolysis (EVH). Because of persistent EVH, up to 72% of eculizumab-treated patients remain anemic, and up to 36% require at least one transfusion per year. Pegcetacoplan (PEG), a C3-inhibitor recently approved by the US FDA to treat adults with PNH, controls IVH and prevents EVH. Studies of PEG treatment in patients with PNH that remained anemic despite eculizumab treatment demonstrated that PEG was superior to eculizumab in achieving improvements in hemoglobin (Hb) levels (Hillmen P, et al., N Engl J Med, 2021 384 (11):1028-1037). Additionally, two early phase open-label trials demonstrated the efficacy of PEG in complement-inhibitor naïve patients with PNH (Wong RS, et al., Blood, 2020 136 [Supplement 1]).Aims: To present results from the Phase 3 PRINCE study (NCT04085601), a multicenter, randomized, open-label, controlled study evaluating the efficacy and safety of PEG compared to standard of care (SOC; excluding complement-inhibitors) in complement-inhibitor naïve patients with PNH.Methods: Fifty-three adult (≥18 years old), complement-inhibitor naïve (no complement-inhibitor treatment [i.e., eculizumab/ravulizumab] within 3 months prior to screening) patients with PNH and Hb levels below the lower limits of normal (males: ≤13.6 g/dL; females: ≤12.0 g/dL), and lactate dehydrogenase (LDH) levels ≥1.5 times the upper limit of normal (1.5x ULN; ≥339 U/L) were enrolled. Patients were randomized 2:1 to receive PEG (1080 mg subcutaneously twice weekly [n=35]) or SOC (excluding complement-inhibitors eculizumab/ravulizumab [n=18]) through Week 26. Patients on SOC had the option to switch to the PEG group if their Hb decreased by ≥2 g/dL from baseline. Co-primary endpoints were Hb stabilization (avoidance of a >1 g/dL decrease in Hb levels in the absence of transfusions) and change from baseline (CFB) in LDH level from baseline to Week 26. Secondary endpoints included CFB in Hb levels, transfusion avoidance (defined as the proportion of subjects who did not require a transfusion through Week 26), and the incidence of adverse events (AEs). Statistical analyses were performed using the Cochran-Mantel-Haenszel test and ANCOVA model.Results: PEG was superior to SOC in both co-primary endpoints. Hb stabilization was achieved by 85.7% (n=30) of PEG-treated patients and 0.0% of SOC patients through Week 26 (p<0.0001). PEG-treated patients demonstrated superior reductions in mean LDH levels from baseline to Week 26 compared to SOC patients (least-squares mean CFB: PEG, -1870.5 U/L; SOC, -400.1 U/L; p<0.0001), and mean LDH levels in PEG-treated patients at Week 26 (mean level: 204.6 U/L) were below the ULN for LDH (226.0 U/L). PEG was also superior to SOC in the secondary endpoints: mean CFB in Hb levels (least-squares mean CFB: PEG, 2.9 g/dL; SOC, 0.3 g/dL; p=0.0019; Week 26 mean Hb: PEG, 12.8 g/dL; SOC, 9.8 g/dL) (Figure) and transfusion avoidance (PEG, 91.4%, n=32; SOC, 5.6%, n=1; p<0.0001). Serious AEs were reported by 8.7% (n=4) of PEG-treated patients and 16.7% (n=3) of SOC patients through Week 26. Two deaths (PEG, 2.9%, n=1, septic shock related to medullary aplasia; SOC, 5.6%, n=1, respiratory failure), both deemed unrelated to treatment, occurred. No events of meningitis or thrombosis were reported in either group. The most common AEs reported during the study were injection site reaction (PEG, 30.4%, n=14; SOC, 0.0%), hypokalemia (PEG, 13.0%, n=6; SOC, 11.1%, n=2), and fever (PEG, 8.7%, n=4; SOC, 0.0%). There were no AEs leading to discontinuation of PEG.Conclusions: Patients with PNH that were naïve to complement-inhibitor treatment demonstrated meaningful hematological and clinical improvements following 26 weeks of PEG treatment. The safety profile of PEG was similar to previous study results and represent a favorable risk-benefit profile. These results provide evidence for the safety and efficacy of PEG treatment in complement-inhibitor naïve patients with PNH.

The effect of cariprazine on patient engagement: Post-hoc analysis of a phase 3 study in patients with predominant negative symptoms of schizophrenia

IntroductionMotivation deficit is a significant aspect of lack of improvement in patients with schizophrenia especially with predominant negative symptoms (PNS). Therefore, improvement depends not only on symptoms reduction and better social functioning but also on patient engagement which is a key but less investigated aspect of successful treatment.ObjectivesTo investigate and compare patient engagement in PNS patients after cariprazine and risperidone treatment characterized by the 11 items of the Positive and Negative Syndrome Scale (PANSS-11).MethodsIn this phase 3 study patients suffering from PNS of schizophrenia (PANSS-FSNS≥24) were randomized to 26 weeks of treatment with either cariprazine or risperidone (target dose 4.5 and 4 mg/day, respectively). To compare the effects of the two drugs on patient engagement the PANSS-11 scale was used. Change from baseline (CfB) on the selected items and PANSS-11 total score were analyzed using mixed model of repeated measures approach without correction for multiplicity.ResultsPANSS-11 total score mean CfB were -11.20 (SD=0.43) for cariprazine-, and -9.44 (SD=0.45) for risperidone-treated patients with a -1.79 (95% CI=-3.01, -0.56) mean difference (p=0.004) in favor of cariprazine. Most item differences were statistically significant (N1, N2, N3, N4, N5, G16) or numerically higher (N6, G7, G13) for cariprazine versus risperidone.ConclusionsCariprazine significantly improved patient engagement in patients with PNS of schizophrenia compared to risperidone based on the PANSS-11 post-hoc analysis. These results suggest that cariprazine treatment may improve not only the symptoms and everyday functioning of PNS patients but their engagement with life.Conflict of interestStudies were funded by Gedeon Richter Plc. and Allergan Plc (prior to its acquisition by AbbVie).

FRI0128 FILGOTINIB PROVIDED RAPID AND SUSTAINED IMPROVEMENTS IN FUNCTIONAL STATUS, PAIN, HEALTH-RELATED QUALITY OF LIFE, AND FATIGUE IN PATIENTS WITH RHEUMATOID ARTHRITIS AND INADEQUATE RESPONSE TO METHOTREXATE: RESULTS FROM THE FINCH 1 STUDY

Background:In the FINCH 1 study, filgotinib (FIL)—an oral, potent, selective Janus kinase 1 inhibitor—in combination with methotrexate (MTX) provided significant improvements in the signs and symptoms of rheumatoid arthritis (RA) in patients (pts) with inadequate response to MTX.1While EULAR guidelines recommend a treat-to-target approach focusing on reducing inflammation to prevent joint damage, physical disability, and mortality, pts consider control of pain and fatigue, along with maintenance of physical function and health-related quality of life (HRQoL), to be important aspects for their care.2,3Objectives:To evaluate the rate and magnitude of change in patient-reported outcomes (PROs) from FINCH 1.Methods:In the FINCH 1 study (NCT02889796), pts with active RA received oral FIL 200 mg + MTX, FIL 100 mg + MTX, PBO + MTX, or subcutaneous adalimumab (ADA) 40 mg + MTX for up to 52 weeks (W); pts receiving PBO at W24 were rerandomised 1:1 to FIL 100 or 200 mg. PROs included the HAQ-DI and VAS pain scale, SF-36, and FACIT-Fatigue questionnaire. The change from baseline (CFB) at each time point was assessed up to W52 for each treatment group. The mixed-effects model for repeated measures was used to compare each FIL group with PBO for the CFB at each time point through W24. The logistic regression model was used to compare each FIL group with PBO for the proportion of pts achieving the minimum clinically important difference (MCID) of ≥0.22 reduction in CFB in HAQ-DI at each time point through W24.Results:Of 1755 pts randomised and treated (475 FIL 200 mg + MTX; 480 FIL 100 mg + MTX; 325 ADA + MTX; and 475 PBO + MTX), 1417 (80.7%) received study drug through W52. As early as W2 through W24, pts receiving either dose of FIL experienced nominally significantly greater (p &lt;0.001) CFB in HAQ-DI and VAS pain scale than those receiving PBO; CFB improvements were maintained through W52 (Fig 1A, B). At W2, compared with PBO (40.2%), a nominally significantly greater proportion of pts achieved the HAQ-DI MCID in both the FIL 200 (52.5%; p &lt;0.001) and 100 mg (46.7%; p = 0.043) groups. This benefit vs PBO was maintained up to W24 and the proportion of pts who achieved a HAQ-DI reduction of ≥0.22 remained ≥75.8% in the FIL 200 mg group and ≥71.5% in the FIL 100 mg group from W12 through W52. FIL provided nominally significantly greater improvement in HRQoL vs PBO at W4 and W12 for both the CFB of the SF-36 Physical Component Summary (PCS) (p &lt;0.001) and Mental Component Summary (MCS) (p ≤0.006); nominal significance was also seen at W24 for CFB of SF-36 PCS (Fig 2A, B). By W4, pts receiving either dose of FIL reported a nominally significantly greater mean CFB in FACIT-Fatigue scores vs PBO (p &lt;0.001); significance was maintained through W24 and improvement in reported fatigue continued through W52 in the FIL groups (Fig 2C). In general, CFB for HAQ-DI, VAS pain scale, and FACIT-Fatigue observed for the FIL groups was higher or comparable to ADA at various time points (Fig 1, 2).Conclusion:Both doses of FIL provided rapid and sustained improvements in functional status, pain, HRQoL, and fatigue compared with PBO for pts with RA and inadequate response to MTX throughout the 52-week period.

Randomized study of the effect of gadopiclenol, a new gadolinium-based contrast agent, on the QTc interval in healthy subjects.

We investigated the effect of gadopiclenol, a new gadolinium-based contrast agent, on the QTc interval at clinical and supraclinical dose, considering the relative hyperosmolarity of this product. This was a single centre, randomized, double-blind, placebo- and positive-controlled, 4-way crossover study. Forty-eight healthy male and female subjects were included to receive single intravenous (i.v.) administrations of gadopiclenol at the clinical dose of 0.1 mmol kg-1 , standard for current gadolinium-based contrast agents, the supraclinical dose of 0.3 mmol kg-1 , placebo and a single oral dose of 400 mg moxifloxacin. The largest time-matched placebo-corrected, mean change from-baseline in QTcF (ΔΔQTcF) was observed 3 hours after administration of 0.1 mmol kg-1 gadopiclenol (2.39 ms, 90% confidence interval [CI]: 0.35, 4.43 ms) and 5 minutes after administration of 0.3 mmol kg-1 (4.81 ms, 90%CI: 2.84, 6.78 ms). The upper limit of the 90% CI was under the threshold of 10 ms, demonstrating no significant effect of gadopiclenol on QTc interval. From 1.5 to 4 hours postdose moxifloxacin, the lower limit of the 90% CI of ΔΔQTcF exceeded 5 ms demonstrating assay sensitivity. Although there was a positive slope, the concentration-response analysis estimated that the values of ΔΔQTcF at the maximal concentration of gadopiclenol at 0.1 and 0.3 mmol kg-1 were 0.41 and 2.23 ms, respectively, with the upper limit of the 90% CI not exceeding 10 ms. No serious or severe adverse events or treatment discontinuations due to adverse events were reported. This thorough QT/QTc study demonstrated that gadopiclenol did not prolong the QT interval at clinical and supraclinical doses and was well tolerated in healthy volunteers. The positive slope of the QTc prolongation vs concentration relationship suggests that hyperosmolarity could be associated with QTc prolongation. However, the amplitude of this effects is unlikely to be associated with proarrhythmia.

Long-term safety and effectiveness of biosimilar insulin glargine in Japanese patients with diabetes mellitus in routine clinical practice: results of a post-marketing safety study

Objective: To evaluate the long-term safety and effectiveness of biosimilar insulin glargine (GLY) in real-world clinical practice.Methods: This prospective, non-interventional, multicenter, observational, post-marketing safety study (PMSS) enrolled Japanese patients with type 1 or 2 diabetes mellitus (T1DM or T2DM) starting GLY therapy, and was required by Japanese Pharmaceutical Affairs Law mandating post-marketing safety surveillance to acquire safety and effectiveness data of biosimilar products. Data collected from the 12-month observation included patient characteristics, adverse events, and blood glucose control.Results: The study enrolled 141 patients with T1DM and 1104 patients with T2DM. Pre-study insulin was used by 94.1% of patients with T1DM and 75.0% with T2DM. 65.4% of patients with T1DM and 64.3% with T2DM switched from the reference product (GLY-switched), while 25.0% with T2DM were insulin-naive. Adverse events were reported by 5.7% and 8.5% in T1DM and T2DM, respectively. Similar incidences were reported in GLY-switched. Adverse events were reported by 10.7% in insulin-naive T2DM. Baseline mean hypoglycemic events/month were 1.8 and 0.1 in T1DM and T2DM, respectively: the mean change from baseline (CFB) was –1.2 (p = .066) and 0.0 (p = .915), respectively. Baseline mean HbA1c was 8.4% and 8.7% in T1DM and T2DM, respectively; the mean CFB was –0.5% (p < .001) and –0.9% (p < .001), respectively, and –1.5% (p < .001) in insulin-naive T2DM.Conclusions: This first long-term Japanese PMSS of GLY demonstrated adverse events, hypoglycemia, and glycemic control consistent with the known GLY profile for T1DM and T2DM patients, in routine clinical practice.

146 Efficacy and Safety of the Asenapine Transdermal Patch, HP-3070, for Schizophrenia: A Phase 3, Randomized, Placebo-Controlled, Inpatient Study

Asenapine is a 2nd-generation antipsychotic currently marketed as a sublingual (SL) tablet in the US for the treatment of schizophrenia. HP-3070, asenapine transdermal system, is a patch for treatment of schizophrenia in adults. Low- and high- HP-3070 doses deliver asenapine concentrations that are similar to SL asenapine 5 mg BID and 10 mg BID, respectively, but with fewer peak and trough fluctuations. In this Phase 3, randomized, double-blind, placebo (PBO)-controlled, 6-week inpatient study, adults with schizophrenia having baseline Positive and Negative Syndrome Scale (PANSS) total score ≥80 and Clinical Global Impression-Severity of Illness Scale (CGI-S) score ≥4 were randomized 1:1:1 to HP 3070 high-dose, HP-3070 low-dose, or PBO.The primary efficacy objective was Week 6 PANSS score change from baseline (CFB) vs PBO.The key secondary objective was Week 6 CGI-S CFB vs PBO. Safety assessments included treatment-emergent adverse events (TEAEs), laboratory results, vital signs, dermal safety, and extrapyramidal symptoms (EPS) assessments. A total of 616 patients were randomized, with 486 patients completing the study. Discontinuation rates were 23.3%, 18.6%, and 21.4% for HP-3070 high-dose, HP-3070 low-dose, and PBO, respectively; withdrawal of consent and AEs were the most common reasons for discontinuation. Demographics and baseline characteristics were well-balanced among treatment groups.For PANSS total score, least squares mean (LSM) (standard error [SE]) estimates of the treatment comparison (HP-3070 vs PBO) for CFB at Week 6 were -4.8 (1.634; 95% CI: -8.06, -1.64; p=0.003) and -6.6 (1.630; 95% CI: 9.81, 3.40; p<0.001) for HP-3070 high- and low-dose, respectively. For CGI-S CFB at Week 6, LSM (SE) for the treatment comparison were 0.4 (0.100; 95% CI: 0.55, 0.16; p<0.001) for HP 3070 high-dose and 0.4 (0.099; 95% CI: 0.64, 0.25; p<0.001) for low-dose.No deaths or serious TEAEs related to study treatment occurred. The HP-3070 safety profile was consistent with SL asenapine. Incidence of TEAEs at the patch application site was higher for HP-3070 (14.2% high-dose, 15.2% low-dose) than for PBO (4.4%); most of these events were mild or moderate in severity. PBO patients had higher rates of psychiatric disorders (24.3% vs 15.7% and 17.6% for HP-3070 high- and low-dose, respectively), with insomnia and anxiety as most common. Study treatment discontinuations due to application site reactions or skin disorders were low (≤0.5%) across treatment groups. There was no marked mean CFB for vital signs or electrocardiogram parameters, nor treatment differences observed on EPS assessments. In this study, HP-3070 was efficacious, safe, and well-tolerated for treating schizophrenia in adults; both doses met primary and key secondary endpoints. As the first transdermal antipsychotic patch in the US, HP-3070 will provide patients a novel treatment option.
