RESUMO
AIMS: LMNA-related dilated cardiomyopathy (DCM) is a rare disease with an incompletely defined phenotype. The phase 3 REALM-DCM trial evaluated a potential disease-modifying therapy for LMNA-related DCM but was terminated due to futility without safety concern. This study utilized pooled data from REALM-DCM to descriptively characterize the phenotype and progression of LMNA-related DCM in a contemporary cohort of patients using common heart failure (HF) measures. METHODS: REALM-DCM enrolled patients with stable LMNA-related DCM, an implanted cardioverter defibrillator or cardiac resynchronization therapy defibrillator, and New York Heart Association (NYHA) Class II/III HF symptoms. RESULTS: Between 2018 and 2022, 77 patients took part in REALM-DCM. The median patient age was 53 years (range: 23-72), and 57% were male. Overall, 88% of patients had a pathogenic or likely pathogenic LMNA variant, and 12% had a variant of uncertain significance with a concordant phenotype. Among patients with confirmed sequencing, 55% had a missense variant. Atrial fibrillation was present in 60% of patients; 79% of all patients had NYHA Class II and 21% had NYHA Class III HF symptoms at baseline. Median (range) left ventricular ejection fraction (LVEF), 6 min walk test (6MWT) distance, Kansas City Cardiomyopathy Questionnaire Overall Summary (KCCQ-OS) score and N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration at baseline were 42% (23-62), 403 m (173-481), 67 (18-97) and 866 pg/mL (57-5248), respectively. LVEF, 6MWT distance and KCCQ-OS score were numerically lower in patients who had NYHA Class III versus II symptoms at baseline (LVEF: 38% vs. 43%; 6MWT distance: 326 vs. 413 m; and KCCQ-OS score: 43 vs. 70), whereas NT-proBNP concentration was higher (1216 vs. 799 pg/mL). Median follow-up was 73 weeks (range: 0.4-218; 73 in NYHA Class II and 75 in NYHA Class III). Patients displayed variable change from baseline in 6MWT, KCCQ-OS and NT-proBNP values during follow-up. Overall, 25% of patients experienced ventricular tachycardia, and 8% had ventricular fibrillation. Ten (13%) patients met the composite endpoint of worsening HF (adjudicated HF-related hospitalization or urgent care visit) or all-cause death; six had NYHA Class II and four had NYHA Class III at baseline. All-cause mortality occurred in 6 (8%) patients; three had NYHA Class II and three had NYHA Class III symptoms at baseline. CONCLUSIONS: Findings confirm the significant morbidity and mortality associated with LMNA-related DCM despite the standard of care management. Typical measures of HF, including 6MWT distance, KCCQ-OS score and NT-proBNP concentration, were variable but correlated with NYHA class. An unmet treatment need remains among patients with LMNA-related DCM. NCT03439514.
RESUMO
Tapinarof is a non-steroidal, topical, aryl hydrocarbon receptor agonist. We evaluated the efficacy and safety of tapinarof cream (1%) in Japanese patients aged ≥18 years with plaque psoriasis in two phase 3 trials, ZBA4-1 and ZBA4-2. ZBA4-1 (N = 158) consisted of a 12-week, double-blind, vehicle-controlled treatment period (period 1) and a 12-week extension treatment period (period 2). Patients were randomized 2:1 to tapinarof or vehicle in period 1; subsequently, all patients who were enrolled in period 2 received tapinarof. ZBA4-2 (N = 305) was a 52-week, open-label, uncontrolled trial in which all patients received tapinarof. In period 1 of ZBA4-1, the proportion of patients who achieved a Physician Global Assessment (PGA) score of 0 (clear) or 1 (almost clear) with ≥2-grade improvement from baseline at week 12 (PGA treatment success, the primary endpoint) was 20.06% in the tapinarof group and 2.50% in the vehicle group (p = 0.0035). The proportion of patients with ≥75% improvement from baseline in the Psoriasis Area and Severity Index (PASI) score at week 12 (PASI75 response, a key secondary endpoint) was 37.7% in the tapinarof group and 3.8% in the vehicle group (p < 0.0001). In ZBA4-2, PGA treatment success rate was 30.0% at week 12, 51.3% at week 24, and 56.3% at week 52, and PASI75 response rate was 50.4% at week 12, 77.5% at week 24, and 79.9% at week 52, indicating that efficacy responses improved over time and were maintained over 52 weeks. Across the two trials, most adverse events (AEs) were mild or moderate; common AEs included folliculitis and contact dermatitis. In summary, tapinarof cream (1%) was efficacious and generally safe for up to 52 weeks of treatment in Japanese patients with plaque psoriasis.
RESUMO
Primary myelofibrosis (PMF) is the most aggressive of the myeloproliferative neoplasms and patients require greater attention and likely require earlier therapeutic intervention. Currently approved treatment options are limited in their selective suppression of clonal proliferation resulting from driver- and coexisting gene mutations. Janus kinase inhibitors are approved for symptomatic patients with higher-risk PMF. Additionally, most ongoing clinical studies focus on patients with higher-risk disease and/or high rates of transfusion dependency. Optimal treatment of early/lower-risk PMF remains to be identified and needs randomized clinical trial evaluations. Pegylated interferon alfa is recommended for symptomatic lower-risk PMF patients based on phase 2 non-randomized studies and expert opinion. Ropeginterferon alfa-2b (ropeg) is a new-generation pegylated interferon-based therapy with favorable pharmacokinetics and safety profiles, requiring less frequent injections than prior formulations. This randomized, double-blind, placebo-controlled phase 3 trial will assess its efficacy and safety in patients with "early/lower-risk PMF", defined as pre-fibrotic PMF or PMF at low or intermediate-1 risk according to Dynamic International Prognostic Scoring System-plus. Co-primary endpoints include clinically relevant complete hematologic response and symptom endpoint. Secondary endpoints include progression- or event-free survival, molecular response in driver or relevant coexisting gene mutations, bone marrow response, and safety. Disease progression and events are defined based on the International Working Group criteria and well-published reports. 150 eligible patients will be randomized in a 2:1 ratio to receive either ropeg or placebo. Blinded sample size re-estimation is designed. Ropeg will be administered subcutaneously with a tolerable, higher starting-dose regimen. The study will provide important data for the treatment of early/lower-risk PMF for which an anti-clonal, disease-modifying agent is highly needed.

Momelotinib, an oral Janus kinase (JAK) 1/2 and activin A receptor type 1 inhibitor, improved symptoms, splenomegaly, and anemia in patients with myelofibrosis (MF). This sub-analysis of SIMPLIFY-1 evaluated the efficacy and safety of momelotinib versus ruxolitinib in Japanese patients with JAK inhibitor (JAKi)-naïve MF. Patients were randomized 1:1 to receive momelotinib 200 mg once daily or ruxolitinib 20 mg twice daily (or modified based on label) for 24 weeks, after which patients could receive open-label momelotinib. The primary endpoint was splenic response rate (SRR; ≥ 35% reduction in spleen volume) at 24 weeks; main secondary endpoints were total symptom score (TSS) response (≥ 50% reduction) and transfusion independence (TI) rates. Fifteen Japanese patients (momelotinib, n = 6; ruxolitinib, n = 9) were enrolled; all completed treatment. At Week 24, SRR was 50.0% with momelotinib and 44.4% with ruxolitinib. TSS response rates were 33.3% and 0%, and TI rates were 83.3% and 44.4%. Any-grade treatment-related adverse event (TRAE) rates were 83.3% with momelotinib and 88.9% with ruxolitinib. Grade 3/4 TRAE rates were 0% and 55.6%, with specific events being anemia (55.6%) and vertigo (11.1%) with ruxolitinib. Momelotinib was well tolerated, improved spleen and symptom responses, and reduced transfusion requirements in Japanese patients with JAKi-naïve MF.
RESUMO
BACKGROUND CONTEXT: SI-6603 (condoliase) is a chemonucleolytic agent approved in Japan in 2018 for the treatment of lumbar disc herniation (LDH) associated with radicular leg pain. Condoliase, a mucopolysaccharidase with high substrate specificity for glycosaminoglycans (GAGs), offers a unique mechanism of action through the degradation of GAGs in the nucleus pulposus. As LDH management is currently limited to conservative approaches and surgical intervention, condoliase could offer a less invasive treatment option than surgery for patients with LDH. PURPOSE: The Discover 6603 study (NCT03607838) evaluated the efficacy and safety of a single-dose injection of SI-6603 (condoliase) vs sham for the treatment of radicular leg pain associated with LDH. STUDY DESIGN/SETTING: A randomized, double-blind, sham-controlled, phase 3 study conducted across 41 sites in the United States. PATIENT SAMPLE: Male and female participants (N=352; aged 30-70 years) with contained posterolateral LDH and unilateral radiculopathy/radicular leg pain for greater than 6 weeks. OUTCOME MEASURES: The primary endpoint was the change from baseline (CFB) in average worst leg pain score at 13 weeks, assessed using the 100-mm visual analogue scale. Key secondary endpoints were CFB in average worst leg pain score at 52 weeks, herniation volume at 13 weeks, and Oswestry Disability Index (ODI) score at 13 weeks. Safety evaluations included adverse events (AEs) and imaging findings. METHODS: Participants were randomized 1:1 to receive a single intradiscal injection of condoliase (1.25 units) or sham injection followed by 52 weeks of observation. The primary and key secondary endpoints were assessed using a mixed model for repeated measures (MMRM) analysis and a protocol-specified multiple imputation (MI) sensitivity analysis on the modified intention-to-treat (mITT) population. A prespecified serial gatekeeping algorithm was used for multiple comparisons. Safety endpoints included AEs, laboratory tests, vital signs, imaging (by X-ray and magnetic resonance imaging [MRI]), and occurrence of posttreatment lumbar surgery. RESULTS: Of the 352 randomized participants, 341 constituted the mITT population (condoliase n=169; sham n=172) and the safety population (condoliase n=167; sham n=174). For the primary endpoint, the condoliase group showed significantly greater improvement in CFB in worst leg pain at Week 13 (least squares mean [LSM] CFB: -41.7) compared with sham injection (-34.2; LSM difference: -7.5; 95% confidence interval [CI]: -14.1, -0.9; p=0.0263) based on the MMRM analysis. CFB in worst leg pain at Week 52 favored condoliase vs sham, but the difference was not statistically significant (p=0.0558), which halted the serial gatekeeping testing algorithm and dictated that the CFB in herniation volume and ODI scores at Week 13 would be considered nonsignificant, regardless of their p values. Treatment group differences in CFB in herniation volume and ODI score favored the condoliase group vs sham at all timepoints. The MI sensitivity analysis showed differences in CFB in worst leg pain at Week 13 (p=0.0223) and Week 52 (p=0.0433) in favor of the condoliase group. Treatment-emergent AEs (TEAEs) were more common in the condoliase group (≥1 TEAE: 71.9%; ≥1 treatment-related TEAE: 28.1%) compared with the sham group (≥1 TEAE: 60.3%; ≥1 treatment-related TEAE: 10.3%). Of the TEAEs, spinal MRI abnormalities and back pain occurred most frequently. No treatment-related serious AEs occurred. CONCLUSIONS: Condoliase met its primary endpoint of significantly improving radicular leg pain at Week 13 and was generally well tolerated in patients with LDH. Chemonucleolysis with condoliase has the potential to provide a less invasive treatment option than surgery for those unresponsive to conservative treatment strategies.
RESUMO
BACKGROUND: Alopecia areata (AA) is a hair loss disorder that can seriously impact quality of life. Janus kinase (JAK) inhibitors, including deuruxolitinib, have previously demonstrated significant hair regrowth in AA. OBJECTIVE: The Phase 3 THRIVE-AA1 randomized, double-blinded, placebo-controlled trial (NCT04518995) evaluated safety and efficacy of the oral JAK1/JAK2 inhibitor deuruxolitinib in adult patients with AA. METHODS: Patients aged 18-65 years with ≥50% hair loss were randomized to deuruxolitinib 8 mg BID, deuruxolitinib 12 mg BID, or placebo for 24 weeks. The primary endpoint was percentage of patients achieving Severity of Alopecia Tool (SALT) score ≤20. A key secondary endpoint was percentage of satisfaction of hair patient-reported outcome (SPRO) responders. RESULTS: Significantly higher proportions of patients taking deuruxolitinib met the primary endpoint (8 mg 29.6%; 12 mg 41.5% versus placebo 0.8%). Both deuruxolitinib doses achieved significant improvements in all secondary endpoints versus placebo, including SPRO (8 mg 42.1%; 12 mg 53.0% versus placebo 4.7%). Most treatment-emergent adverse events were mild or moderate, consistent with other oral JAK inhibitors. LIMITATIONS: Further studies are required to understand longer-term safety, efficacy, and impact of treatment cessation. CONCLUSION: Both doses of deuruxolitinib were effective for hair regrowth. Patient satisfaction aligned with hair growth.
RESUMO
Patients with sarcomatoid renal cell carcinoma (sRCC) have a poor prognosis. In the randomised, double-blind phase 3 IMmotion010 trial (NCT03024996), adjuvant atezolizumab did not demonstrate a disease-free survival (DFS) benefit versus placebo in the overall population of patients with locoregional renal cell carcinoma with an increased risk of recurrence following surgery. This prespecified subgroup analysis of efficacy and safety was completed in 104 patients with sRCC. Baseline characteristics were similar between treatment arms. At a median follow-up of 45 mo, the median DFS was not evaluable (NE; 95% confidence interval [CI], 12 mo-NE) in the atezolizumab arm (n = 37) and 23 mo (95% CI, 11-NE) in the placebo arm (n = 66; hazard ratio 0.77 [95% CI, 0.44-1.4]). In the sRCC subgroup, grade 3/4 treatment-related adverse events (TRAEs) occurred in one patient (2.7%) in the atezolizumab arm and two patients (3.0%) in the placebo arm. By comparison, 54 of 353 patients (15%) and 16 of 317 patients (5.0%) with non-sarcomatoid histology reported grade 3/4 TRAEs in the respective arms. In conclusion, the difference in DFS was not statistically significant between adjuvant atezolizumab and placebo in patients with sRCC. The safety profile was similar between patients with sRCC and non-sRCC. PATIENT SUMMARY: Patients with a specific type of locoregional kidney cancer (tumours with sarcomatoid features) were treated with atezolizumab or placebo after surgery. Slightly more patients treated with atezolizumab lived longer without the disease getting worse than those treated with placebo, although this finding was not statistically significant. The side effects were similar to those seen in patients with other types of kidney cancer treated with atezolizumab in the same study (IMmotion010). In patients with sarcomatoid kidney cancer, atezolizumab was tolerable and may be more effective than placebo, but this requires further study.
RESUMO
INTRODUCTION: Difamilast is the first selective phosphodiesterase 4 inhibitor approved for atopic dermatitis (AD) in Japan. A phase 3, 52-week, open-label study is ongoing to establish efficacy and safety of difamilast ointments in infants with AD aged 3 to < 24 months because a clinical study has not been conducted in this population. METHODS: This study consisted of a 4-week primary evaluation period in which difamilast 0.3% ointment was applied twice daily to Japanese infants aged 3 to < 24 months (n = 41) and an ongoing 48-week long-term extension period in which difamilast 0.3% or 1% ointment was applied based on existing symptoms. The data on efficacy and safety of difamilast were obtained as of an interim report in the study period. RESULTS: The response rate in Investigator's Global Assessment score was 45.0% at week 1, which was maintained at 56.1% at week 4 and 63.4% at the interim report. Infants achieved the response rate in Eczema Area and Severity Index 75 (improvement of ≥ 75%) of 47.5% at week 1, which further improved to 82.9% at week 4 and 78.1% at the interim report. Adverse events (AEs) were reported in 22 (53.7%) infants in the primary evaluation period: of those the most frequent AE was nasopharyngitis (19.5%) followed by dermatitis contact (7.3%). As of the interim report, 36 (87.8%) infants experienced AEs: of those, nasopharyngitis (70.7%) and gastroenteritis (22.0%) were most frequently observed. The total AEs were mostly mild or moderate in severity. No investigational medicinal product-related AEs and no AEs leading to discontinuation were reported. CONCLUSION: Difamilast ointments applied twice daily to Japanese infants with AD aged 3 to < 24 months is effective and well tolerated as of the interim report in the study period. The final results will be reported in the near future. CLINICAL TRIAL REGISTRATION: Clinical Trials. gov identifier: NCT05372653.
RESUMO
Kaiser et al. offer management recommendations for transplant-eligible, high-risk multiple myeloma (HRMM), derived from recent trials exploring treatment intensification in the various phases of front-line therapy. The definition of HRMM continues to evolve with emergence of novel genomic insights and impact of modern therapies, underscoring the need to expand beyond traditional interphase fluorescence in situ hybridization cytogenetics and International Staging System staging for a precise risk assessment. Despite progress, ongoing challenges in treatment delivery and tolerability underscore the urgency for exploring novel approaches like T-cell redirecting bispecific antibodies and chimeric antigen receptor T-cell to enhance outcomes in this complex patient population.

RESUMO
BACKGROUND: The recently approved AS01E-adjuvanted respiratory syncytial virus (RSV) prefusion F protein-based vaccine for older adults (RSVPreF3 OA) demonstrated high efficacy against RSV-related disease in ≥60-year-olds. METHODS: This ongoing phase 3 study in ≥60-year-olds evaluates immune persistence until 3 years after RSVPreF3 OA vaccination. Here, we describe interim results on humoral and cell-mediated immunogenicity, reactogenicity, and safety until 1 year post-dose 1. RESULTS: In total, 1653 participants were vaccinated. One month post-dose 1, neutralization titers increased 10.5-fold (RSV-A) and 7.8-fold (RSV-B) vs pre-dose 1. Titers then declined to levels 4.4-fold (RSV-A) and 3.5-fold (RSV-B) above pre-dose 1 at month 6 and remained 3.1-fold (RSV-A) and 2.3-fold (RSV-B) above pre-dose 1 levels after 1 year. RSVPreF3-binding immunoglobulin G levels and CD4+ T-cell frequencies showed similar kinetics. Solicited administration-site and systemic adverse events (mostly mild to moderate and transient) were reported by 62.2% and 49.5% of participants. Serious adverse events were reported by 3.9% of participants within 6 months post-dose 1; 1 case was considered vaccine related. CONCLUSIONS: One RSVPreF3 OA dose elicited cell-mediated and RSV-A- and RSV-B-specific humoral immune responses that declined over time but remained above pre-dose 1 levels for at least 1 year. The vaccine was well tolerated with an acceptable safety profile. Clinical Trials Registration. NCT04732871 (ClinicalTrials.gov).
Respiratory syncytial virus (RSV) is a major cause of illness and hospitalization in older adults. An RSV vaccine for older adults developed by GSK was recently approved. The vaccine was well tolerated and provided protection against RSV disease in adults aged ≥60 years during at least 1 RSV season. In this ongoing study, we are evaluating the magnitude and durability of the immune response, as well as vaccine safety, until 3 years after vaccination of adults aged ≥60 years from 5 countries. Here, we report the results of an interim analysis until 1 year after vaccination with 1 dose. In total, 1653 participants were vaccinated. We found that the vaccine induced a strong immune response that was evident 1 month after vaccination, after which it declined but persisted for at least 1 year. Study participants most often reported pain at the injection site, muscle pain, tiredness, and headache as adverse reactions, which were mostly mild to moderate and of short duration. One serious adverse reaction was considered related to the vaccine. The long-term immune response that was observed in this study is consistent with the vaccine providing protection during at least 1 RSV season.

Background: CV-NCOV-005 was conducted to generate additional safety and immunogenicity data for the former CVnCoV SARS-CoV-2 mRNA vaccine candidate in healthcare workers (HCW). Methods: Randomised, observer blinded, placebo-controlled, phase 3 trial performed at the University Medical Center Mainz, Germany. HCWs aged ≥18 years with no history of SARS-CoV-2 infection/positive serology were randomly assigned to receive two doses of CVnCoV, or two doses of placebo (0.9% NaCl). The primary objectives were to expand the safety database of CVnCoV and assess antibody responses against SARS-CoV-2. Primary safety and reactogenicity outcomes included solicited adverse events (AEs) within 7 days after each dose and unsolicited AEs within 28 days after each dose, with safety follow-up for 13 months after first vaccination. Since HCWs became eligible to receive an authorised vaccine during enrolment and efficacy results from HERALD CVnCoV trial were made available on 30th of June 2021, this study was unblinded and converted to an open label design. Results: Most participants in the CVnCoV group reported at least one solicited AE, a relatively high number being Grade 3 (43.3% in CVnCoV group and 6.4% in placebo group). Most AEs were short in duration and did not affect vaccine compliance. The percentage of participants with unsolicited AEs up to 28 days after any dose was slightly higher in CVnCoV group (37.0%) compared with placebo group (31.2%). IgG binding antibodies against the receptor binding domain of the SARS-CoV-2 spike protein were observed after vaccination, with higher seroconversion rates and antibody levels after the second dose. Conclusion: No safety concerns for CVnCoV were identified up to 1 year post second dose. IgG responses against SARS-CoV-2 were observed after two doses, with a higher seroconversion rate and antibody levels observed after second vaccination.Study registration: ClinicalTrials.gov NCT04674189, study period: 23rd of December 2020 to 8th of June 2022.
RESUMO
INTRODUCTION: There is no approved effective drug for diabetic peripheral neuropathic pain (DPNP) in China. Gabapentinoids including mirogabalin have shown promise, although data in Chinese patients are scarce. METHODS: This phase 3, multicenter, randomized, double-blind, placebo-controlled trial investigated the efficacy and safety of mirogabalin for treating DPNP in China. Mirogabalin was administered at 5 mg twice daily for the first week and uptitrated to 15 mg twice daily for a total duration of 14 weeks. The primary efficacy endpoint was the change from baseline in weekly average daily pain score (ADPS) at week 14; secondary endpoints included the ADPS responder rate, Short-Form McGill Pain Questionnaire visual analogue scale score, patient global impression of change (PGIC), average daily sleep interference score (ADSIS), EuroQol 5-dimensions 5-levels (EQ-5D-5L), and incidence of treatment-emergent adverse events (TEAEs). RESULTS: Of 393 patients (mirogabalin, n = 196; placebo n = 197), the mean age was 58.2 years (mirogabalin, 58.7 years; placebo, 57.7 years) and 54.2% were male (mirogabalin, 56.1%; placebo, 52.3%). Mirogabalin elicited a greater change from baseline in the weekly ADPS vs. placebo at week 14: least-squares mean difference (95% confidence interval) vs. placebo - 0.39 (- 0.74, - 0.04), p = 0.0301. PGIC, ADSIS, and EQ-5D-5L data reflected significantly better improvements for patients receiving mirogabalin vs. placebo. The incidence of TEAEs was 75.0% and 75.1% in the mirogabalin and placebo groups, respectively. Most TEAEs were mild or moderate, and the incidence of TEAEs leading to treatment discontinuation was 2.6% in the mirogabalin group and 1.5% in the placebo group. CONCLUSIONS: Although the effect size of mirogabalin was reduced due to the placebo effect, mirogabalin is a safe and effective treatment option for Chinese patients with DPNP. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT04094662.
RESUMO
INTRODUCTION: The understanding of atopic dermatitis (AD) pathogenesis has rapidly expanded in recent years, catalyzing the development of new targeted monoclonal antibody treatments for AD. AREAS COVERED: This review aims to summarize the latest clinical and molecular data about monoclonal antibodies that are in later stages of development for AD, either in Phase 3 trials or in the pharmacopoeia for up to 5 years, highlighting the biologic underpinning of each drug's mechanism of action and the potential modulation of the AD immune profile. EXPERT OPINION: The therapeutic pipeline of AD treatments is speedily progressing, introducing the potential for a personalized medical approach in the near future. Understanding how targeting pathogenic players in AD modifies disease progression and symptomatology is key in improving therapeutic choices for patients and identifying ideal patient candidates.

BACKGROUND: The interim analysis of the randomized phase 3 ESCORT-1st study demonstrated significantly longer overall survival (OS) and progression-free survival (PFS) for camrelizumab-chemotherapy than placebo-chemotherapy in untreated advanced/metastatic esophageal squamous cell carcinoma (ESCC). Here, we present the final analysis of this study and investigate potential indicators associated with OS. METHODS: Patients were randomized 1:1 to receive camrelizumab (200 mg) or placebo, both in combination with up to six cycles of paclitaxel (175 mg/m2) and cisplatin (75 mg/m2). All treatments were administered intravenously every 3 weeks. The co-primary endpoints were OS and PFS assessed by the independent review committee. FINDINGS: As of April 30, 2022, the median OS was significantly longer in the camrelizumab-chemotherapy group compared to the placebo-chemotherapy group (15.6 [95% confidence interval (CI): 14.0-18.4] vs. 12.6 months [95% CI 11.2-13.8]; hazard ratio [HR]: 0.70 [95% CI 0.58-0.84]; one-sided p < 0.0001), with 3-year OS rates of 25.6% and 12.8% in the two groups, respectively. The 2-year PFS rates were 20.4% in the camrelizumab-chemotherapy group and 3.4% in the placebo-chemotherapy group. Adverse events were consistent with those reported in the interim analysis. Higher PD-L1 expression correlated with extended OS, and multivariate analysis identified sex and prior history of radiotherapy as independent indicators of OS. CONCLUSIONS: The sustained and significant improvement in efficacy with camrelizumab-chemotherapy compared to placebo-chemotherapy, along with the absence of accumulating or delayed toxicities, supports the long-term use of camrelizumab-chemotherapy as a standard therapy in untreated advanced/metastatic ESCC.

RESUMO
Background: Janus kinase (JAK) inhibition is a promising approach for treating vitiligo. We aimed to assess the efficacy and safety of upadacitinib, an oral selective JAK inhibitor, in adults with non-segmental vitiligo. Methods: This was a phase 2, multicentre, randomised, double-blind, placebo-controlled, dose-ranging study completed at 33 clinical centres in the United States, Canada, France, and Japan. Eligible patients were aged 18-65 years with non-segmental vitiligo and had a Facial Vitiligo Area Scoring Index (F-VASI) ≥0.5 and a Total Vitiligo Area Scoring Index (T-VASI) ≥5. Patients were randomly assigned (2:2:2:1:1) using an interactive response technology to receive upadacitinib 6 mg (UPA6), upadacitinib 11 mg (UPA11), upadacitinib 22 mg (UPA22), or placebo (PBO; preassigned to switch to either UPA11 or UPA22 in period 2) once daily for 24 weeks (period 1). For weeks 24-52 (period 2), patients randomly assigned to upadacitinib continued their treatment, and patients receiving PBO switched to their preassigned upadacitinib dose in a blinded fashion. The primary endpoint was the percent change from baseline in F-VASI at week 24. Efficacy was analysed in the intention-to-treat population, and safety was examined in all randomly assigned patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT04927975. Findings: Between June 16, 2021, and June 27, 2022, 185 patients (including 115 [62%] who were female and 70 [38%] who were male) were randomly assigned to UPA6 (n = 49), UPA11 (n = 47), UPA22 (n = 43), or PBO (n = 46). At week 24, the LS mean difference versus PBO in the percent change from baseline in F-VASI was -7.60 (95% CI -22.18 to 6.97; p = 0.3037) for UPA6, -21.27 (95% CI -36.02 to -6.52; p = 0.0051) for UPA11, and -19.60 (95% CI -35.04 to -4.16; p = 0.0132) for UPA22. The LS mean difference versus PBO in the percent change from baseline in T-VASI was -7.45 (95% CI -16.86 to 1.96; p = 0.1198) for UPA6, -10.84 (95% CI -20.37 to -1.32; p = 0.0259) for UPA11 and -14.27 (95% CI -24.24 to -4.30; p = 0.0053) for UPA22. Ongoing treatment with upadacitinib induced continuous skin repigmentation over time without reaching a plateau through week 52. The rates for study drug discontinuation and serious treatment-emergent adverse events (TEAEs) were higher in the UPA22 group than in the UPA11 and UPA6 groups. Eight serious TEAEs, including one death of unknown cause and one case of infiltrating lobular breast carcinoma, were reported through 52 weeks; only two serious TEAEs (coronary artery arteriosclerosis [UPA6 (n = 1)] and non-fatal ischemic stroke [UPA11 (n = 1)]) were deemed by the investigator to have a reasonable possibility of being related to study drug. The one case of breast cancer in the UPA11 group was deemed unrelated to study drug, and the one death of unknown cause in the UPA22 group was reviewed and adjudicated and was deemed to be unrelated to study drug. The most common TEAEs were COVID-19, headache, acne, and fatigue. No new safety signals were observed. Interpretation: Upadacitinib monotherapy led to substantial repigmentation of both facial and total body vitiligo lesions and may offer an effective treatment option for adults with extensive non-segmental vitiligo. Based on these findings, upadacitinib 15 mg is being investigated in adults and adolescents with non-segmental vitiligo in an ongoing phase 3 randomised controlled trial. Funding: AbbVie Inc.
RESUMO
AIM: In the global phase 3 POETYK PSO-1 and PSO-2 trials, significantly greater proportions of deucravacitinib-treated patients met the coprimary endpoints (PASI 75, sPGA 0/1) at Week 16 versus placebo or apremilast-treated patients. This analysis evaluated onset of action and maintenance of response in patients randomized to deucravacitinib and placebo only. METHODS: Adults with moderate to severe plaque psoriasis at baseline were randomized 1:2:1 to oral placebo, deucravacitinib, or apremilast. Onset of action was determined through changes from baseline in mean PASI, BSA, BSA × sPGA, and DLQI. Maintenance of response was assessed using PASI 75, PASI 90, PASI 100, sPGA 0/1, and sPGA 0 response rates through Week 52 in patients who were treated continuously with deucravacitinib, crossed over from placebo to deucravacitinib at Week 16, or received deucravacitinib and achieved PASI 75 by Week 24. RESULTS: Deucravacitinib showed significantly higher increases in mean percent change from baseline in PASI versus placebo by Week 1. Significant improvement versus placebo was observed in all other efficacy measures by Week 8. Efficacy with deucravacitinib was maintained through Week 52. CONCLUSION: Deucravacitinib displayed efficacy as early as 1 week and clinical responses were maintained over 52 weeks in patients with moderate to severe plaque psoriasis.

BACKGROUND: Biomarkers offer potential alternatives to endoscopies in monitoring ulcerative colitis (UC) progression and therapeutic response. This post hoc analysis of the ELEVATE UC clinical program assessed potential predictive values of fecal calprotectin (fCAL) and high-sensitivity C-reactive protein (hsCRP) as biomarkers and associated responses to etrasimod, an oral, once-daily, selective sphingosine 1-phosphate (S1P)1,4,5 receptor modulator for the treatment of moderately to severely active UC, in 2 phase 3 clinical trials. METHODS: In ELEVATE UC 52 and ELEVATE UC 12, patients were randomized 2:1 to 2 mg of etrasimod once daily or placebo for 52 or 12 weeks, respectively. Fecal calprotectin/hsCRP differences between responders and nonresponders for efficacy end points (clinical remission, clinical response, endoscopic improvement-histologic remission [EIHR]) were assessed by Wilcoxon P-values. Sensitivity and specificity were presented as receiver operating characteristics (ROC) curves with area under the curve (AUC). RESULTS: In ELEVATE UC 52 and ELEVATE UC 12, 289 and 238 patients received etrasimod and 144 and 116 received placebo, respectively. Baseline fCAL/hsCRP concentrations were generally balanced. Both trials had lower week-12 median fCAL levels in week-12 responders vs nonresponders receiving etrasimod for clinical remission, clinical response, and EIHR (all Pâ <â .001), with similar trends for hsCRP levels (all Pâ <â .01). For etrasimod, AUCs for fCAL/hsCRP and EIHR were 0.85/0.74 (week 12; ELEVATE UC 52), 0.83/0.69 (week 52; ELEVATE UC 52), and 0.80/0.65 (week 12; ELEVATE UC 12). CONCLUSIONS: Fecal calprotectin/hsCRP levels decreased with etrasimod treatment; ROC analyses indicated a prognostic correlation between fCAL changes during induction and short-/long-term treatment response.
We show associations between fecal calprotectin (fCAL) and high-sensitivity C-reactive protein (hsCRP) levels with efficacy outcomes among patients receiving 2 mg of etrasimod once daily, and that fCAL levels may be an early indicator of the achievement of long-term efficacy end point achievement.
RESUMO
Background: Vaccine effectiveness against SARS-CoV-2 infection has been somewhat limited due to the widespread dissemination of the Omicron variant, its subvariants, and the immune response dynamics of the naturally infected with the virus. Methods: Twelve subjects between 3-17 years old (yo), vaccinated with two doses of CoronaVac®, were followed and diagnosed as breakthrough cases starting 14 days after receiving the second dose. Total IgGs against different SARS-CoV-2 proteins and the neutralizing capacity of these antibodies after infection were measured in plasma. The activation of CD4+ and CD8+ T cells was evaluated in peripheral blood mononuclear cells stimulated with peptides derived from the proteins from the wild-type (WT) virus and Omicron subvariants by flow cytometry, as well as different cytokines secretion by a Multiplex assay. Results: 2 to 8 weeks post-infection, compared to 4 weeks after 2nd dose of vaccine, there was a 146.5-fold increase in neutralizing antibody titers against Omicron and a 38.7-fold increase against WT SARS-CoV-2. Subjects showed an increase in total IgG levels against the S1, N, M, and NSP8 proteins of the WT virus. Activated CD4+ T cells showed a significant increase in response to the BA.2 subvariant (p<0.001). Finally, the secretion of IL-2 and IFN-γ cytokines showed a discreet decrease trend after infection in some subjects. Conclusion: SARS-CoV-2 infection in the pediatric population vaccinated with an inactivated SARS-CoV-2 vaccine produced an increase in neutralizing antibodies against Omicron and increased specific IgG antibodies for different SARS-CoV-2 proteins. CD4+ T cell activation was also increased, suggesting a conserved cellular response against the Omicron subvariants, whereas Th1-type cytokine secretion tended to decrease.

Background: In ORIENT-15 study, sintilimab plus chemotherapy demonstrated significant improvement on overall survival (OS) versus placebo plus chemotherapy in first-line treatment of advanced esophageal squamous cell carcinoma (ESCC). Here, we report effect of sintilimab plus chemotherapy on health-related quality of life (HRQoL) in patients with advanced ESCC. Methods: From December 14, 2018 to August 28, 2022, HRQoL was evaluated in all randomized patients using European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 items (QLQ-C30), EORTC Quality of Life Questionnaire Oesophageal Cancer Module 18 items (QLQ-OES18), and visual analogue scale (VAS) of the EuroQol five-dimensional five-level questionnaire (EQ-5D-5L). Mean scores of each scale were described by treatment group through week 60. Least-squares mean (LSM) score change from baseline through week 24 were analyzed using the mixed-model repeated-measures method. Time to the first onset of deterioration (TTD) and OS for each scale were estimated. Clinical Trials Registration: NCT03748134. Findings: As of August 28, 2022, 689 of 690 enrolled patients were assessed for HRQoL analysis (sintilimab group: 340, placebo group: 349). Median follow-up was 32.2 months. Differences in LSM favored sintilimab over placebo for QLQ-C30 social functioning (LSM difference: 3.06, 95% CI: 0.55 to 5.57; P = 0.0170), pain (-2.24, 95% CI: -4.30 to -0.17; P = 0.0337), fatigue (-2.24, 95% CI: -4.46 to -0.02; P = 0.0479), constipation (-3.27, 95% CI -5.49 to -1.05; P = 0.0039), QLQ-OES18 pain (-1.77, 95% CI -3.11 to -0.43; P = 0.0097), trouble swallowing saliva (-2.09, 95% CI: -3.77 to -0.42; P = 0.0146), and choked when swallowing (-3.23, 95% CI: -5.60 to -0.86; P = 0.0076). TTD favored sintilimab over placebo for QLQ-OES18 dysphagia (Hazard ratio [HR]: 0.76, 95% CI: 0.61-0.94, P = 0.0104), and trouble swallowing saliva (HR: 0.48, 95% CI: 0.35-0.67, P < 0.0001). Improved OS were observed in patients with better performance in several functioning and symptom scales of QLQ-C30 and QLQ-QES18. Interpretation: The statistically significant differences of several HRQoL scales and improvements in delayed deterioration observed in our study further support the use of sintilimab plus chemotherapy as first-line treatment for advanced ESCC. Funding: This study was funded by Innovent Biologics and was co-funded by Eli Lilly.
RESUMO
Venetoclax, a highly selective BCL-2 inhibitor, combined with hypomethylating agents (HMAs) azacitidine or decitabine, is approved for the treatment of newly diagnosed acute myeloid leukemia (ND AML) in patients who are ineligible to receive intensive chemotherapy. Previous clinical studies initiated venetoclax plus HMA in an inpatient setting owing to concerns of tumor lysis syndrome (TLS). This study (NCT03941964) evaluated the efficacy and safety of venetoclax plus HMA in a United States community-based outpatient setting in patients with ND AML (N = 60) who were treatment naïve for AML, ineligible to receive intensive chemotherapy, had no evidence of spontaneous TLS at screening, and were deemed as appropriate candidates for outpatient initiation of venetoclax plus HMA by the investigator. Patients received venetoclax in combination with azacitidine (75 mg/m2) or decitabine (20 mg/m2) for up to 6 cycles during the study. With a median time on study of 18.3 weeks, the best response rate of composite complete remission was 66.7%, and the overall post-baseline red blood cell (RBC) and platelet transfusion independence rate was 55.0%, consistent with results of studies in which treatment was initiated in an inpatient setting. Key adverse events included nausea, anemia, thrombocytopenia, neutropenia, and white blood cell count decrease of any grade (≥50% of patients). The observed safety profile was generally consistent with that of venetoclax plus HMA observed in inpatient AML studies. With close monitoring, 2 cases of TLS were identified, appropriately managed, and the patients were able to continue study treatment.
