Psoriasis vulgaris patient with psoriatic arthritis managed with interleukin-17A inhibitor: Balancing benefits and adverse effects.

Psoriasis vulgaris is a significant health problem and up to 30% of the patients are most likely to develop psoriatic arthritis. Secukinumab, an interleukin-17A (IL-17A) inhibitor, is used to treat patients with moderate-to-severe plaques associated with psoriatic arthritis. The aim of this case report was to highlight the efficacy of secukinumab treatment in a patient with both psoriasis vulgaris and psoriatic arthritis focusing the how to balance the benefits and adverse effects. A 36-year-old female came to Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia with chief complaint of itchy and scaly red plaques almost all over the body. The patient also experienced pain in both knees, both ankle joints and index finger as well as thumb in the right hand in the last year. The patient was diagnosed with psoriasis vulgaris and psoriatic arthritis, then treated with phototherapy and 15 mg of oral methotrexate each week for four weeks. Due to no improvement of the initial treatment, the patient received emollient and secukinumab at a dose of 300 mg/week subcutaneously for five weeks. The lesions began to disappear and the joint pain began to relieve. Secukinumab therapy was continued with a dose of 300 mg/month for six months. However, after six months, the patient complained of acnes appeared on the face. Therefore, the maintenance dose of secukinumab was decreased to 150 mg/month. After the reduced maintenance therapy was given, the patient came back with no complained of acnes. The erythematous plaques on trunk, back, arms and legs have subsided, as well as the joint pain. This case highlights that in a moderate-to-severe psoriasis associated with psoriatic arthritis, secukinumab is highly effective. However, since the potential adverse effects, education and regular follow-up are needed to analyze the success of the treatment and to be able to manage the adverse effects.

Neoadjuvant Treatment for a cT4cN+ HER2+ Breast Cancer: Case Report of a Therapeutic Success.

BACKGROUND: HER2 positive disease accounts for 15-20% of early breast cancer. Achieving a pathological complete response after neoadjuvant chemotherapy (NACT) improves prognosis and decreases risk of recurrence. CASE REPORT: Our case report aimed to highlight an emblematic clinical success and benefit of NACT with the addition of pertuzumab to the standard trastuzumab/taxane/anthracycline combination in a patient with a 9 cm breast neoplasm and extensive lymph node involvement (>4 pathological lymph nodes). CONCLUSION: Achieving a complete pathological response with NACT, should be the main goal, especially in patients with triple negative and HER2 positive breast cancer.

Adverse Event Profile of Atezolizumab, Bevacizumab, Carboplatin, and Paclitaxel Combination Therapy Based on JADER.

BACKGROUND/AIM: There have been advances in the development of immune checkpoint inhibitors for monotherapy and combination therapy with other anticancer agents in recent years. The combination of bevacizumab, carboplatin, and paclitaxel with atezolizumab, an anti-programmed death ligand 1 antibody (ABCP therapy), has been reported to be effective for treating non-small cell lung cancer. However, reports on its adverse events are limited. In this study, a survey and disproportionality analysis based on the Japanese Adverse Drug Event Report (JADER) database was conducted to elucidate the adverse event profile of ABCP therapy. MATERIALS AND METHODS: The reporting odds ratio (ROR) and information component were used as indicators for the disproportionality analysis. The ROR was also used to assess the changes in the reporting intensity with combination therapy, and the mutual exclusivity of the 95% confidence interval between the compared groups was considered. RESULTS: The reported adverse events of ABCP therapy mirrored those of the individual drugs that constituted it. ABCP therapy enhanced the reporting intensity of adverse events related to leukocytes and the skin, while decreased those related to interstitial lung disease and hepatic function abnormality as immune-related adverse events caused by atezolizumab, and gastrointestinal perforation caused by bevacizumab. CONCLUSION: Our analysis of data from the JADER database has revealed the adverse event profile of ABCP therapy. Our findings emphasize the importance of effectively managing febrile neutropenia and skin-related adverse events in ABCP therapy.

Real Clinical Practice of Combined Atezolizumab Plus Chemotherapy in Patients With Small Cell Lung Cancer.

BACKGROUND/AIM: Atezolizumab, an anti-PD-L1 antibody, has been increasingly administered in combination with chemotherapy to patients with small cell lung cancer (SCLC). This study aimed to determine how patients with extensive disease (ED) -SCLC responded to atezolizumab with chemotherapy and found factors affecting long-term response and survival. PATIENTS AND METHODS: This study focused on patients with SCLC who were treated with a combination of atezolizumab and chemotherapy in Japan between 2019 and 2023. Patient information and tumor response were analyzed, along with adverse events. We compared data and estimated survival probabilities. RESULTS: In our clinical trial, 95 patients with SCLC who received this treatment had a median progression-free survival of 6.0 months and a median overall survival of 15.0 months. Immune-related adverse events were observed in 13.7% of the patients, with grade 3 or higher in 5.3%. The efficacy and immune-related adverse events associated with this treatment regimen were comparable to those reported in previous clinical trials. Progression-free survival >2 years was observed in a small number of patients (5.3%). CONCLUSION: Our research will offer important insights for the future care of patients with extensive-stage SCLC by utilizing atezolizumab in combination with chemotherapy. Accumulation and confirmation of clinical practice results will have important implications for the future implementation of this therapy.

Projected environmental and public health benefits of extended-interval dosing: an analysis of pembrolizumab use in a US national health system.

BACKGROUND: Health care is a major source of greenhouse gas emissions, leading to climate change and public health harms. Changes are needed to improve the environmental sustainability of health-care practices, but such changes should not sacrifice patient outcomes or financial sustainability. Alternative dosing strategies that reduce the frequency with which specialty drugs are administered, without sacrificing patient outcomes, are an attractive possibility for improving environmental sustainability. We sought to inform environmentally sustainable cancer care by estimating and comparing the environmental and financial effects of alternative, clinically equivalent strategies for pembrolizumab administration. METHODS: We conducted a retrospective analysis using a cohort of patients from the Veterans Health Administration (VHA) in the USA who received one or more pembrolizumab doses between May 1, 2020, and Sept 30, 2022. Using baseline, real-world administration of pembrolizumab, we generated simulated pembrolizumab use data under three near-equivalent counterfactual pembrolizumab administration strategies defined by combinations of weight-based dosing, pharmacy-level vial sharing and dose rounding, and extended-interval dosing (ie, every 6 weeks). For each counterfactual dosing strategy, we estimated greenhouse gas emissions related to pembrolizumab use across the VHA cohort using a deterministic environmental impact model that estimated greenhouse gas emissions due to patient travel, drug manufacture, and medical waste as the primary outcome measure. FINDINGS: We identified 7813 veterans who received at least one dose of pembrolizumab-containing therapy in the VHA during the study period. 59 140 pembrolizumab administrations occurred in the study period, of which 46 255 (78·2%) were dosed at 200 mg every 3 weeks, 12 885 (21·8%) at 400 mg every 6 weeks, and 14 955 (25·3%) were coadministered with infusional chemotherapies. Adoption of weight-based, extended-interval pembrolizumab dosing (4 mg/kg every 6 weeks) and pharmacy-level stewardship strategies (ie, dose rounding and vial sharing) for all pembrolizumab infusions would have resulted in 24·7% fewer administration events than baseline dosing (44 533 events vs 59 140 events) and an estimated 200 metric tons less CO2 emitted per year as a result of pembrolizumab use within the VHA (650 tons vs 850 tons of CO2, a relative reduction of 24%), largely due to reductions in distance travelled by patients to receive treatment. Similar results were observed when weight-based and extended-interval dosing were applied only to pembrolizumab monotherapy and pembrolizumab in combination with oral therapies. INTERPRETATION: Alternative pembrolizumab administration strategies might have environmental advantages over the current dosing and compounding paradigms. Specialty medication dosing can be optimised for health-care spending and environmental sustainability without sacrificing clinical outcomes. FUNDING: None.

First-line venetoclax combinations versus chemoimmunotherapy in fit patients with chronic lymphocytic leukaemia (GAIA/CLL13): 4-year follow-up from a multicentre, open-label, randomised, phase 3 trial.

BACKGROUND: In the primary analysis report of the GAIA/CLL13 trial, we found that venetoclax-obinutuzumab and venetoclax-obinutuzumab-ibrutinib improved undetectable measurable residual disease (MRD) rates and progression-free survival compared with chemoimmunotherapy in patients with previously untreated chronic lymphocytic leukaemia. However, to our knowledge, no data on direct comparisons of different venetoclax-based combinations are available. METHODS: GAIA/CLL13 is an open-label, randomised, phase 3 study conducted at 159 sites in ten countries in Europe and the Middle East. Eligible patients were aged 18 years or older, with a life expectancy of at least 6 months, an Eastern Cooperative Oncology group performance status of 0-2, a cumulative illness rating scale score of 6 or lower or a single score of 4 or lower, and no TP53 aberrations. Patients were randomly assigned (1:1:1:1), with a computer-generated list stratified by age, Binet stage, and regional study group, to either chemoimmunotherapy, venetoclax-rituximab, venetoclax-obinutuzumab, or venetoclax-obinutuzumab-ibrutinib. All treatments were administered in 28-day cycles. Patients in the chemoimmunotherapy group received six cycles of treatment, with patients older than 65 years receiving intravenous bendamustine (90 mg/m2, days 1-2), whereas patients aged 65 years or younger received intravenous fludarabine (25 mg/m2, days 1-3) and intravenous cyclophosphamide (250 mg/m2, days 1-3). Intravenous rituximab (375 mg/m2, day 1 of cycle 1; 500 mg/m2, day 1 of cycles 2-6) was added to chemotherapy. In the experimental groups, patients received daily venetoclax (400 mg orally) for ten cycles after a 5-week ramp-up phase starting on day 22 of cycle 1. In the venetoclax-rituximab group, intravenous rituximab (375 mg/m2, day 1 of cycle 1; 500 mg/m2, day 1 of cycles 2-6) was added. In the obinutuzumab-containing groups, obinutuzumab was added (cycle 1: 100 mg on day 1, 900 mg on day 2, and 1000 mg on days 8 and 15; cycles 2-6: 1000 mg on day 1). In the venetoclax-obinutuzumab-ibrutinib group, daily ibrutinib (420 mg orally, from day 1 of cycle 1) was added until undetectable MRD was reached in two consecutive measurements (3 months apart) or until cycle 36. The planned treatment duration was six cycles in the chemoimmunotherapy group, 12 cycles in the venetoclax-rituximab and the venetoclax-obinutuzumab group and between 12 and 36 cycles in the venetoclax-obinutuzumab-ibrutinib group. Coprimary endpoints were the undetectable MRD rate in peripheral blood at month 15 for the comparison of venetoclax-obinutuzumab versus standard chemoimmunotherapy and investigator-assessed progression-free survival for the comparison of venetoclax-obinutuzumab-ibrutinib versus standard chemoimmunotherapy, both analysed in the intention-to-treat population (ie, all patients randomly assigned to treatment) with a split α of 0·025 for each coprimary endpoint. Both coprimary endpoints have been reported elsewhere. Here we report a post-hoc exploratory analysis of updated progression-free survival results after a 4-year follow-up of our study population. Safety analyses included all patients who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov, NCT02950051, recruitment is complete, and all patients are off study treatment. FINDINGS: Between Dec 13, 2016, and Oct 13, 2019, 1080 patients were screened and 926 were randomly assigned to treatment (chemoimmunotherapy group n=229; venetoclax-rituximab group n=237; venetoclax-obinutuzumab group n=229; and venetoclax-obinutuzumab-ibrutinib group n=231); mean age 60·8 years (SD 10·2), 259 (28%) of 926 patients were female, and 667 (72%) were male (data on race and ethnicity are not reported). At data cutoff for this exploratory follow-up analysis (Jan 31, 2023; median follow-up 50·7 months [IQR 44·6-57·9]), patients in the venetoclax-obinutuzumab group had significantly longer progression-free survival than those in the chemoimmunotherapy group (hazard ratio [HR] 0·47 [97·5% CI 0·32-0·69], p<0·0001) and the venetoclax-rituximab group (0·57 [0·38-0·84], p=0·0011). The venetoclax-obinutuzumab-ibrutinib group also had a significantly longer progression-free survival than the chemoimmunotherapy group (0·30 [0·19-0·47]; p<0·0001) and the venetoclax-rituximab group (0·38 [0·24-0·59]; p<0·0001). There was no difference in progression-free survival between the venetoclax-obinutuzumab-ibrutinib and venetoclax-obinutuzumab groups (0·63 [0·39-1·02]; p=0·031), and the proportional hazards assumption was not met for the comparison between the venetoclax-rituximab group versus the chemoimmunotherapy group (log-rank p=0·10). The estimated 4-year progression-free survival rate was 85·5% (97·5% CI 79·9-91·1; 37 [16%] events) in the venetoclax-obinutuzumab-ibrutinib group, 81·8% (75·8-87·8; 55 [24%] events) in the venetoclax-obinutuzumab group, 70·1% (63·0-77·3; 84 [35%] events) in the venetoclax-rituximab group, and 62·0% (54·4-69·7; 90 [39%] events) in the chemoimmunotherapy group. The most common grade 3 or worse treatment-related adverse event was neutropenia (114 [53%] of 216 patients in the chemoimmunotherapy group, 109 [46%] of 237 in the venetoclax-rituximab group, 127 [56%] of 228 in the venetoclax-obinutuzumab group, and 112 [48%] of 231 in the venetoclax-obinutuzumab-ibrutinib group). Deaths determined to be associated with study treatment by the investigator occurred in three (1%) patients in the chemoimmunotherapy group (n=1 due to each of sepsis, metastatic squamous cell carcinoma, and Richter's syndrome), none in the venetoclax-rituximab and venetoclax-obinutuzumab groups, and four (2%) in the venetoclax-obinutuzumab-ibrutinib group (n=1 due to each of acute myeloid leukaemia, fungal encephalitis, small-cell lung cancer, and toxic leukoencephalopathy). INTERPRETATION: With more than 4 years of follow-up, venetoclax-obinutuzumab and venetoclax-obinutuzumab-ibrutinib significantly extended progression-free survival compared with both chemoimmunotherapy and venetoclax-rituximab in previously untreated, fit patients with chronic lymphocytic leukaemia, thereby supporting their use and further evaluation in this patient group, while still considering the higher toxicities observed with the triple combination.

Beyond the Label: Real-World Side Effects Experienced With FDA-Approved Drugs for Non-Melanoma Skin Cancers.

With immunotherapy historically focused on cutaneous melanoma, there has been a new wave of systemic medications available for treating non-melanoma skin cancers including basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and Merkel cell carcinoma (MCC). The immune checkpoint inhibitors approved by the FDA target programmed cell death protein 1 (PD-1) and the Hedgehog (Hh) signaling pathway. These medications have expanded treatment options; however, side effects are an important consideration. We used the FDA Adverse Events Reporting System (FAERS) to characterize the most prevalent, real-world side effects experienced by patients on these agents. Muscle spasms (23.45%), alopecia (16.06%), ageusia (12.02%), taste disorder (11.91%), and fatigue (11.67%) were the five most common side effects reported with medications used for BCC treatment. Logistic regression analysis showed males on vismodegib for BCC having greater odds of experiencing muscle spasms (aOR 1.33, P<0.001) and ageusia (aOR 1.34,  P<0.001) versus females, who were more likely to exhibit alopecia (aOR 1.82, P<0.001) and nausea (aOR 1.96, P<0.001). With SCC treatment, the 5 most reported adverse events were fatigue (5.58%), rash (3.59%), asthenia (3.59%), pruritus (3.19%), and pyrexia (2.79%). Patients taking cemiplimab-rwlc for BCC compared to SCC were more likely to experience disease progression (aOR 10.98, P=0.02). With medication labels providing an excessively daunting list of side effects, we characterize practical side effects seen in patients receiving systemic treatments for non-melanoma skin cancers.  J Drugs Dermatol. 2024;23(5):301-305. doi:10.36849/JDD.7968.

[Effectiveness and safety of biological therapy in patients with severe asthma in a real clinical practice].

AIM: To assess effectiveness and safety of biological therapy in patients with severe asthma during 5 yr follow-up. MATERIALS AND METHODS: We recruited 129 adult outpatients (29% males) aged 18-81 yrs with severe asthma were followed up during 5 yrs and were examined for every 3-6 months. Eighty five patients were treated by conventional therapy (ICS/LABA ± tiotropium, montelukast, OCS) only and 44 pts additionally received biologicals (оmalizumab - 9 pts, мepolizumab - 8 pts, benralizumab - 11 pts, dupilumab - 16 pts). Pulmonary function tests were measured by dry spirometer (2120, Vitalograph Ltd., UK). Eosinophil count in blood was assessed by automatic haemoanalyser. Fraction of exhaled nitric oxide was measured by a chemiluminescence analyzer (LR4100; Logan Research, UK). Asthma control and quality of life were assessed by using Russian versions of ACQ-5 and SGRQ. RESULTS: The use of biologicals led to a more significant reduction of exacerbations and OCS use, improvement of lung function, asthma control and quality of life, decrease of eosinophil and fraction of exhaled nitric oxide than conventional therapy of severe asthma (p<0.05). Systemic side effects were not registered, frequency of local adverse reactions (edema, hyperemia and itching at injection site) was 14%. CONCLUSION: Long-term use of biologicals added to conventional therapy in patients with severe asthma is characterized by high effectiveness and favorable safety profile.

[Blood eosinophilia in patients with severe bronchial asthma and chronic polypous rhinosinusitis treated with dupilumab: A review].

Bronchial asthma and chronic polypous rhinosinusitis are diseases associated with a T2-inflammatory immune response. These nosologies can be combined, creating the preconditions for a more severe course of multimorbidity, requiring the use of genetic engineering biological therapy. Dupilumab is a monoclonal antibody that can specifically bind to the alpha subunit of the interleukin-4 receptor and block the action of interleukins 4 and 13, which play a key role in the development of T2 inflammation. Numerous studies have demonstrated the high effectiveness of this medicament. The use of dupilumab in some cases may be accompanied by an increase in eosinophils in the blood. This article presents scientific base and our own experience in treating patients with dupilumab-associated eosinophilia, in addition we describe an algorithm for examining this group of patients for the purpose of timely diagnosis of diseases such as eosinophilic granulomatosis with polyangiitis, eosinophilic pneumonia, etc. It should be noted that in the most cases eosinophilia during targeted therapy with dupilumab is temporary and does not cause clinical manifestations.

Efficacy and safety of an early response-based tapering regimen of tocilizumab in children with systemic juvenile idiopathic arthritis.

INTRODUCTION: Systemic juvenile idiopathic arthritis (sJIA) is a distinct disease subset, with a poorer prognosis compared with other JIA subsets. Tocilizumab has an important role in the management of sJIA refractory to standard initial therapy. However, no specific guidelines exist for the tapering of tocilizumab therapy in sJIA, which could have implications on the overall cost and side effects of treatment. METHODS: This was an observational study which included 21 children with refractory sJIA, who were initially put on injection tocilizumab every 2 weekly, with subsequent dosing tapered to 4 weekly and 6 weekly intervals based on JIA ACR 70 responses at 12 and 24 weeks, respectively. The primary outcome at week 36 included JIA ACR 30, 50, 70, and 90 response rates with other efficacy and safety measures as secondary outcomes. RESULTS: At 36 weeks, JIA ACR 30, 50, 70, and 90 responses were observed in 90.5%, 90.5%, 71.4%, and 52.4% patients respectively along with significant improvement in hematological and inflammatory parameters. The mean prednisolone dose could be reduced from 0.54 to 0.13 mg/kg/day and around 29% patients were able to discontinue steroids altogether. No serious adverse events were recorded. With drug tapering, we could curtail on 26% of the total tocilizumab dose that would have been otherwise required on the continuous 2 weekly protocol. CONCLUSIONS: Tocilizumab, used in an early response-based tapering regimen, was both safe and efficacious in children with sJIA refractory to standard therapy. Larger and longer duration studies are required to further validate our observations.

Effect of cytokines on advanced hepatocellular carcinoma prognosis receiving radiotherapy and tislelizumab plus anlotinib: a single-center phase II clinical trial.

The purpose of this study was to investigate the relationship between circulating cytokines and liver function and prognosis of patients with advanced hepatocellular carcinoma (HCC) treated with radiotherapy combined with tislelizumab and anlotinib. The liver function indexes and pre-treatment levels of cytokines in 47 patients were measured by chemical method and flow cytometry. The median follow-up was 23.1 months. The objective response and the disease control rates were 46.8% and 68.1%, while overall survival (OS) and progression-free survival (PFS) were 12.6 and 11.4 months, respectively. Adverse events (2.1%) were grade 3-4. In addition to stage, intrahepatic metastasis and Child-Pugh score, pre-treatment interleukin-6 (IL-6) was the main cytokine affecting OS and PFS (p < 0.05). The OS (14.63 pg/mL as cutoff value) and PFS (9.85 pg/mL as cutoff value) of patients with low IL-6 levels exceeded those with high levels (21.0 and 6.9, 15.8 and 10.0 months, respectively). The risks of death and disease progression were reduced by 63.0% (HR = 0.37, 95% CI: 0.19-0.72) and 43.0% (HR = 0.57, 95% CI: 0.22-1.47), respectively. Pre-treatment IL-6 levels may be a simple and effective prognostic indicator for patients with advanced HCC treated with radiotherapy combined with immunotargeted therapy.

The effect of liver metastases on clinical efficacy of first-line programmed death-1 inhibitor plus chemotherapy in esophageal squamous cell carcinoma: A post hoc analysis of ASTRUM-007 and meta-analysis.

OBJECTIVE: To explore the efficacy of serplulimab plus chemotherapy in esophageal squamous cell carcinoma (ESCC) patients with liver metastases. METHODS: A post hoc exploratory analysis of ASTRUM-007 study was performed, focusing on the association between the liver metastases status and the clinical outcomes. A systematic literature search of electronic databases was conducted to identify eligible randomized controlled trials for the meta-analysis. Study-level pooled analyses of hazard ratios (HRs) for PFS according to liver metastases were performed. RESULTS: The post hoc analysis of ASTRUM-007 showed that although patients with liver metastases had a worse prognosis comparing with the non-liver metastases patients in both treatment arms (serplulimab plus chemotherapy arm: median PFS, 5.7 vs. 6.6 months, HR 1.57 [95% CI, 1.15-2.13]; median OS, 13.7 vs. 15.3 months, HR 1.48 [95% CI, 1.09-1.98]; placebo plus chemotherapy arm: median PFS, 4.3 vs. 5.5 months, HR 1.58 [95% CI, 1.01-2.39]; median OS, 10.3 vs. 11.2 months, HR 1.32 [95% CI, 0.84-2.00]), OS and PFS benefits derived from serplulimab plus chemotherapy versus placebo plus chemotherapy in this study were observed in both patients with liver metastases (HR of PFS: 0.60; 95% CI, 0.37-0.97; HR of OS: 0.68; 95% CI, 0.43-1.11) and the non-liver metastases patients (HR of PFS: 0.62; 95% CI, 0.49-0.80; HR of OS: 0.69; 95% CI, 0.55-0.87) with similar magnitude. Three randomized controlled trials were included in the meta-analysis. Pooled HRs demonstrated that the addition of anti-PD-1 antibodies significantly improved PFS compared to chemotherapy alone regardless of liver metastases status. CONCLUSIONS: This study reveals that the presence of liver metastases is a poor prognostic factor but does not affect the improvements in both PFS and OS brought by adding PD-1 blockade to chemotherapy in ESCC patients. Predictive biomarkers for survival in these patients warrant further investigation.

Dose escalation of biologic treatment in patients with moderate-to-severe psoriasis in Japan.

Patients receiving interleukin (IL)-inhibiting biologics for moderate-to-severe psoriasis (PsO) may be treated with escalated doses to optimize outcomes. This study evaluated escalation prevalence in a Japanese claims analysis of patients with PsO diagnosis preceding IL-inhibiting biologic treatment and ≥1 post-induction maintenance claim (index date) with sufficient data availability from January 2014 to May 2022. Patients with non-persistence were excluded. Expected daily dose (EDD) was calculated as the recommended maintenance dose divided by the treatment interval. Dose escalation was defined as ≥2 claims showing a ≥20% increase in the observed average daily dose (ADD) over the EDD (with sensitivities requiring ≥1 claim and ≥30%). Significant differences were tested using multivariable regressions. The study included 982 unique patients treated with brodalumab (BRO; n = 104), guselkumab (GUS; n = 207), ixekizumab (IXE; n = 159), risankizumab (RIS; n = 135), secukinumab (SEC; n = 215) and ustekinumab (UST; n = 196). Within 12 months, dose escalation was observed for all IL-inhibiting biologics other than GUS and RIS: 44.4% for UST, 37.2% for IXE, 3.4% for SEC and 1.4% for BRO. In multivariable-adjusted analyses, odds of dose escalation were significantly lower for all products relative to UST. In sensitivities, escalation was observed for all products except RIS.

The efficacy and safety of short-term and low-dose IL-2 combined with tocilizumab to treat rheumatoid arthritis.

Background: Immunotherapy targeting factors related to immune imbalance has been widely employed for RA treatment. This study aimed to evaluate the efficacy and safety of low-dose interleukin (IL)-2 combined with tocilizumab (TCZ), a biologics targeting IL-6, in RA patients. Methods: Fifty adults with active RA who met the criteria with complete clinical data were recruited, and divided into three groups: control group (n=15), IL-2 group (n=26), and IL-2+TCZ group (n=9). In addition to basic treatment, participants in the IL-2 group received IL-2 (0.5 MIU/day), while participants in the IL-2+TCZ group received IL-2 (0.5 MIU/day) along with one dose of TCZ (8 mg/kg, maximum dose: 800 mg). All subjects underwent condition assessment, laboratory indicators and safety indicators detection, and records before treatment and one week after treatment. Results: Compared with the baseline, all three groups showed significant improvement in disease conditions, as evidenced by significantly reduced disease activity indicators. The low-dose IL-2 and combination treatment groups demonstrated a violent proliferation of Tregs, while the absolute number of Th1, Th2, and Th17 cells in the latter group showed a decreasing trend. The decrease in the Th17/Treg ratio was more pronounced in the IL-2+TCZ groups. No significant adverse reactions were observed in any of the patients. Conclusion: Exogenous low doses of IL-2 combined TCZ were found to be safe and effective in reducing effector T cells and appropriately increasing Treg levels in RA patients with high effector T cell levels. This approach helps regulate immune homeostasis and contributes to the prevention of disease deterioration.

Improvements in advanced hepatocellular carcinoma to repeat implementation of primary protocol after cancer progression occurs following sequential systemic therapy and a clinical trial: A case report.

INTRODUCTION: Systemic therapy is recommended for patients with advanced hepatocellular carcinoma (aHCC). However, drug resistance occurs over time when patients receive systemic therapy, resulting in cancer progression. Due to the lack of relevant clinical trials, optimizing subsequent treatments after cancer progression remains elusive. PATIENT CONCERNS: A 52-year-old male patient presented with epigastric discomfort and fatigue for almost 1 month with a past history of chronic hepatitis B virus infection for 30 years. DIAGNOSIS: Based on the patient's performance status, tumor status assessed by computed tomography, liver function, he was diagnosed with HCC at BCLC stage C. INTERVENTIONS AND OUTCOMES: He first received transarterial chemoembolization (TACE) combined with sintilimab and lenvatinib as first-line treatment and experienced 10-month progression-free survival. After cancer progression, the patient participated in a clinical trial of ABSK-011, a novel fibroblast growth factor receptor 4 inhibitor, with a frustrating result. Then, the patient underwent TACE and received sintilimab plus lenvatinib again. Surprisingly, the tumor had a partial response, and the patient's serum alpha-fetoprotein returned to normal. LESSONS: The combined treatment of TACE plus systemic therapy might be an appropriate subsequent treatment.

Assessment of effectiveness and impact of universal prophylaxis with nirsevimab for prevention of hospitalizations due to respiratory syncytial virus in infants. The NIRSE-GAL study protocol.

Nirsevimab has been recently licensed for universal RSV prophylaxis in infants. NIRSE-GAL is a three-year population-based study initiated in Galicia in September 2023. It aims to evaluate nirsevimab effectiveness against RSV-related hospitalizations lower respiratory tract infections (LRTI), severe RSV, all-cause LRTI, and all-cause hospitalization. NIRSE-GAL also aims to estimate nirsevimab impact on primary healthcare use in the short and mid-term, children's wheezing and asthma, and medical prescriptions for RSV. The immunization campaigns will be scheduled based on the expected start week for the RSV season and will last the whole season. Immunization will be offered to: i) infants born during the campaign (seasonal), ii) infants < 6 months at the start of the campaign (catch-up), and iii) infants with high-risk factors, aged 6-24 months at the start of the campaign (high-risk). The follow-up period will start: i) the immunization date for all immunized infants, ii) the start of the campaign, for the non-immunized catch-up or high-risk groups, or iii) the birthdate for the non-immunized seasonal group. Infants will be followed up until outcome occurrence, death, or end of study. Nirsevimab effectiveness will be estimated using Poisson and Cox regression models. Sensitivity and stratified analyses will be undertaken. The number of averted cases and the number needed to immunize will be estimated. Immunization failure and nirsevimab safety will be monitored. NIRSE-GAL was approved by the ethics committee of Galicia (CEIC 2023-377) and registered in ClinicalTrials.gov (ID: NCT06180993). Findings will be mainly shared via peer-reviewed publications and scientific conferences.

Tocilizumab use for optic nerve compression in thyroid eye disease: a prospective longitudinal cohort.

PURPOSE: To assess the effectiveness of tocilizumab in reverting the signs and symptoms of dysthyroid optic neuropathy (DON) in thyroid eye disease and the need for emergency orbital decompression. The secondary outcomes are to identify the optimal number of tocilizumab cycles to achieve the primary outcome, to analyze the association between thyroid stimulating immunoglobulin (TSI), clinical activity score (CAS) and proptosis in response to the treatment and the need for rehabilitative orbital decompression. METHODS: Prospective longitudinal cohort study that included 13 patients who had unilateral or bilateral dysthyroid optic neuropathy (DON) due to severe and progressive sight-threatening thyroid eye disease based on the CAS system. Patients were seen in this facility starting from July 2017, and all had received intravenous tocilizumab. RESULTS: Initial visual acuity mean was 0.52 ± 0.38 and the final were 0.93 ± 0.11 with a mean difference of 0.41 and P < 0.00245. The mean CAS prior to the initiation of the treatment was 7.92 ± 0.66 and the final was 2.85 ± 1.03 with mean difference of 5.07 and P < 0.00001. Initial mean proptosis was 24.85 ± 2.31 and the final was 21.78 ± 2.18 with a mean difference of 3.07 and P < 0.000497. No emergency orbital decompression was performed. TSI was high initially in all cases with a wide range of 2.4 to 40 IU/L and with a mean of 10.70 ± 13.40. The final TSI mean was 2.90 ± 3.90 with a mean difference of 7.81 and significant P value (P < 0.0272). CONCLUSION: Tocilizumab use in optic nerve compression showed promising results as it can be the primary or an alternative treatment option.

Cost-effectiveness of additional serplulimab to chemotherapy in metastatic squamous non-small cell lung cancer patients.

Objective: To estimate the cost-effectiveness of adding serplulimab to chemotherapy for metastatic squamous non-small cell lung cancer (NSCLC) patients in a first-line setting from a Chinese perspective. Methods: A three-health state partitioned survival model was constructed to simulate disease development. The clinical data used in the model were derived from the ASTRUM-004 clinical trial. Only direct medical costs were included, and the utilities were derived from published literature. The quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) were employed to evaluate health outcomes. Additionally, a sensitivity analysis was performed to verify the robustness of the results. Results: Compared with chemotherapy alone, the addition of serplulimab resulted in an increase of 0.63 QALYs with an incremental cost of $5,372.73, leading to an ICER of $8,528.14 per QALY. This ICER was significantly lower than 3 times China's per capita GDP. The one-way sensitivity analysis suggested that the utility of PFS was the most sensitive factor on ICERs, followed by the price of serplulimab. Conclusion: The combination of serplulimab and chemotherapy has been shown to be a cost-effective initial treatment option for patients with metastatic squamous NSCLC with the commonly accepted willingness-to-pay threshold of 3 times the GDP per capita per QALY in China.

Comparative effectiveness of tildrakizumab 200 mg versus tildrakizumab 100 mg in psoriatic patients with high disease burden or above 90 kg of body weight: a 16-week multicenter retrospective study - IL PSO (Italian landscape psoriasis).

PURPOSE: Tildrakizumab is a selective inhibitor of IL-23 approved for the treatment of moderate-to-severe plaque psoriasis in two dosages. We conducted a 16-week multicenter retrospective study to compare the effectiveness and safety of tildrakizumab 200 mg versus tildrakizumab 100 mg in patients with a high disease burden or high body weight. MATERIALS AND METHODS: Our retrospective study included 134 patients treated with tildrakizumab 200 mg and 364 patients treated with tildrakizumab 100 mg from 28 Italian Dermatology Units affected by moderate-to-severe plaque psoriasis. The patients had a body weight above 90 kg or a high disease burden (Psoriasis Area and Severity Index [PASI] ≥ 16 or the involvement of difficult-to-treat areas). We evaluated the effectiveness of tildrakizumab at the week-16 visit in terms of PASI90, PASI100 and absolute PASI ≤ 2. RESULTS: After 16 weeks of treatment with tildrakizumab 200 mg, PASI90 was reached by 57.5% of patients and PASI100 by 39.6% of patients. At the same time point, 34.3% and 24.2% of patients treated with tildrakizumab 100 mg achieved PASI90 and PASI100, respectively. CONCLUSIONS: Our data suggest that tildrakizumab 200 mg has better effectiveness than tildrakizumab 100 mg in patients with a body weight ≥ 90 kg and a high disease burden.
