Real-world safety and effectiveness of adalimumab in patients with hidradenitis suppurativa: A 52-week analysis of a postmarketing surveillance study in Japan. J Dermatol 2023; 50:1034-1044. [PMID: 37264993 DOI: 10.1111/1346-8138.16835] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 04/16/2023] [Accepted: 05/03/2023] [Indexed: 06/03/2023]
Abstract
Adalimumab is a human monoclonal antibody against tumor necrosis factor-α that was approved in Japan for the treatment of hidradenitis suppurativa (HS), a chronic recurrent inflammatory skin disease. We report the results of the final analysis of the postmarketing surveillance (PMS) study (ClinicalTrials.gov: NCT03894956), which evaluated the 52-week safety and efficacy of adalimumab for HS treatment in real-world clinical practice in Japan. This multicenter, prospective, open-label, observational study (March 2019 to May 2021) included patients with HS treated with subcutaneous adalimumab at doses following the package insert. The primary endpoint was safety, and the secondary endpoints were effectiveness, including HS clinical response (HiSCR), C-reactive protein (CRP), skin pain, and Dermatology Life Quality Index (DLQI). Of the 84 patients registered at 65 sites, 83 patients were included in the analyses. Adverse drug reactions (ADRs) were reported by 10 (12.0%) patients; two patients reported a serious ADR, including one patient with serious infection. Other safety events of special interest reported were liver disorder and dermatitis psoriasiform (one patient each). Almost all patients with ADRs were recovering or had recovered, except for one patient who experienced a serious ADR of liver disorder and died. At 12 weeks, 55.4% of patients achieved HiSCR; this increased to 60.5% and 62.8% at 24 and 52 weeks of adalimumab treatment, respectively. Significant reductions from baseline in CRP (P < 0.05), skin pain (P < 0.0001), and DLQI (P < 0.0001) were observed at all time points. The results from this PMS study demonstrated that long-term adalimumab treatment is well tolerated and effective in patients with HS in real-world clinical practice in Japan.

Real-world safety and effectiveness of adalimumab in patients with hidradenitis suppurativa: 12-week interim analysis of post-marketing surveillance in Japan. J Dermatol 2022; 49:411-421. [PMID: 35040156 PMCID: PMC9305509 DOI: 10.1111/1346-8138.16297] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 12/19/2021] [Accepted: 12/21/2021] [Indexed: 11/28/2022]
Abstract
Hidradenitis suppurativa (HS) is a painful chronic skin disease characterized by abscesses, nodules, and tunnels in the skin. Adalimumab, a monoclonal antibody against tumor necrosis factor‐α, is approved for the treatment of HS in Europe, the USA, and Japan. This multicenter, open‐label, post‐marketing, observational study (ClinicalTrials.gov: NCT03894956) evaluated the safety and effectiveness of adalimumab in routine clinical practice in Japan (March 2019–May 2021). Patients with HS were treated with s.c. doses of adalimumab according to the dosage described in the package insert. The primary end‐point was safety (data cut‐off, December 2020). Secondary end‐points assessed effectiveness, including HS Clinical Response (HiSCR), skin pain, Dermatology Life Quality Index (DLQI), and C‐reactive protein (CRP). Here, we report 12‐week interim effectiveness results. A total of 84 eligible patients from 65 sites were enrolled; 83 patients were included in this analysis. Mean age was 42.0 years, mean body mass index was 26.9 kg/m2, 78.3% of patients were male, 61.4% had Hurley stage III disease, 39.8% had a disease duration ≥10 years, and 7.2% had a family history of HS. The most common affected sites were the axilla (60.2%), buttocks (59.0%), and the inguinal and femoral regions (47.0%). Mean abscess and inflammatory nodule count was 13.0 (standard deviation, 12.0). Among patients with a comorbidity (57.8%), the most common were diabetes mellitus, hypertension, and chronic kidney disease. No patient reported a serious infection or any safety event of special interest. One patient died from a serious adverse event of cardiac failure unrelated to adalimumab. At week 12, 57.4% of patients achieved HiSCR, and significant reductions from baseline in skin pain, DLQI (both p < 0.0001), and CRP (p = 0.0029) were observed. These results support the administration of adalimumab as a well‐tolerated and effective treatment for Japanese patients with HS in real‐world clinical practice.

Abstract
The purpose of the present study is to investigate the concordance of treatment preferences between patients and physicians in prostate cancer (PCa) in Japan. An internet-based discrete choice experiment was conducted. Patients and physicians were asked to select their preferred treatment from a pair of hypothetical treatments consisting of four attributes: quality of life (QOL), treatment effectiveness, side effects, and accessibility of treatment. The data were analyzed using a conditional logistic regression model to calculate coefficients and the relative importance (RI) of each attribute. A total of 103 PCa patients and 127 physicians responded. The study looked at 37 patients considered as advanced PCa and 66 who were non-advanced PCa. All of the physicians were urologists. Advanced PCa patients ranked the attributes as follows: treatment effectiveness (RI: 32%), accessibility of treatment (RI: 26%), QOL (RI: 23%), and side effects (RI: 19%). For physicians, the RI ranking was the same as for advanced PCa patients; treatment effectiveness (RI: 29%), accessibility of treatment (RI: 27%), QOL (RI: 26%), and side effects (RI: 18%). For non-advanced PCa patients, accessibility of treatment ranked the highest RI (27%) and treatment effectiveness ranked as the lowest RI (14%). Our study suggests that the ranking of the attributes was consistent between advanced PCa patients and physicians. The most influential attribute was treatment effectiveness. Treatment preferences also vary by disease stage.

Abstract
INTRODUCTION Golimumab has been proven as an effective treatment for rheumatoid arthritis in clinical trials. However, there is a scarcity of data regarding its use in elderly patients in a real-world setting. This study aims to evaluate the safety, effectiveness, and treatment persistence of golimumab in elderly Japanese patients (≥ 75 years) with rheumatoid arthritis. METHODS This study was a post hoc analysis of post-marketing surveillance data on 5137 Japanese patients with active rheumatoid arthritis who received golimumab for 24 weeks. The study population was divided into two age groups (younger: < 75 years and elderly: ≥ 75 years), and the safety, effectiveness, and treatment persistence of golimumab were assessed. Also, the reasons for discontinuing golimumab treatment were analyzed by multi-logistic regression. RESULTS During golimumab treatment over 24 weeks, younger and elderly groups exhibited comparable improvement of disease activity as measured by EULAR response criteria with similar overall rates of adverse events. However, the survival curve of golimumab for elderly patients was significantly different from that for younger patients due largely to the discontinuation at 4 weeks. The most common reason for discontinuation in elderly patients was patient choice, while it was disease progression in younger patients. Analysis of elderly patients who discontinued treatment by their own decision identified EULAR good response as a factor associated with continuation of golimumab treatment whereas no predictive factor associated with discontinuation was identified. CONCLUSIONS The safety and effectiveness of golimumab treatment in elderly Japanese patients aged 75 years or older were comparable to those in younger patients in real-world clinical practice. Analysis of the survival curves suggested that continuous use of golimumab might further improve clinical benefit of golimumab in elderly patients, underpinning the importance of effective communication between physicians and elderly patients based on the treat-to-target strategy.

Abstract
INTRODUCTION The aim of this study was to investigate real-world treatment patterns for use of golimumab and concomitant medications in Japanese patients with rheumatoid arthritis. METHODS This study was a post hoc retrospective analysis from post-marketing surveillance data on 2350 Japanese patients with moderate/severe rheumatoid arthritis who received golimumab for 24 weeks. The study population was divided based on initiation treatment or dose adjustment patterns with golimumab, methotrexate, or oral glucocorticoids. RESULTS Logistic regression analysis revealed that the baseline factors associated with administration of golimumab (100 mg) were higher body weight, failure of prior biological therapy (bio-failure), no previous methotrexate use, and respiratory disease, while previous methotrexate use and absence of renal impairment or respiratory disease were associated with concomitant methotrexate therapy, and previous glucocorticoid use was associated with concomitant glucocorticoid therapy. The following associations were identified with regard to dose adjustment during treatment: bio-failure, no previous methotrexate use, previous csDMARDs use, presence of respiratory disease, allergy history, and higher CRP for golimumab dose escalation; shorter disease duration, previous GC, and no previous methotrexate use for methotrexate dose escalation; no prior biological therapy and renal impairment for methotrexate dose reduction; no previous GC use for glucocorticoid dose escalation; and absence of Steinbrocker's stage II/III/IV, absence of Steinbrocker's class II, no bio-failure, and no previous csDMARDs use for glucocorticoid dose reduction. CONCLUSIONS This study revealed that various baseline factors were associated with initiation of treatment and dose adjustment of golimumab, methotrexate, or oral glucocorticoids, reflecting both the treatment strategies of physicians for improving RA symptoms and/or reducing adverse events.

Abstract
Species-specific restriction fragment length polymorphism in the intron of the androgen receptor gene (ar5) was found in glass to silver-stage individuals of Anguilla japonica (n = 51) and A. marmorata (n = 21). The sequence analysis of 16S rDNA from 328 anguillid leptocephali collected in the North Equatorial Current of the western North Pacific Ocean revealed the specimens to be A. japonica (n = 194), A. marmorata (n = 128), A. bicolor pacifica (n = 5) and A. luzonensis (n = 1). All leptocephali of A. japonica and A. marmorata were monomorphic and did not share an allele at the ar5 locus, indicating that the two species are reproductively isolated.

Crystal structural characterization reveals novel oligomeric interactions of human voltage-dependent anion channel 1. Protein Sci 2017; 26:1749-1758.

Abstract
Voltage-dependent anion channel 1 (VDAC1), which is located in the outer mitochondrial membrane, plays important roles in various cellular processes. For example, oligomerization of VDAC1 is involved in the release of cytochrome c to the cytoplasm, leading to apoptosis. However, it is unknown how VDAC1 oligomerization occurs in the membrane. In the present study, we determined high-resolution crystal structures of oligomeric human VDAC1 (hVDAC1) prepared by using an Escherichia coli cell-free protein synthesis system, which avoided the need for denaturation and refolding of the protein. Broad-range screening using a bicelle crystallization method produced crystals in space groups C222 and P221 21 , which diffracted to a resolution of 3.10 and 3.15 Å, respectively. Each crystal contained two hVDAC1 protomers in the asymmetric unit. Dimer within the asymmetrical unit of the crystal in space group C222 were oriented parallel, whereas those of the crystal in space group P221 21 were oriented anti-parallel. From a model of the crystal in space group C222, which we constructed by using crystal symmetry operators, a heptameric structure with eight patterns of interaction between protomers, including hydrophobic interactions with β-strands, hydrophilic interactions with loop regions, and protein-lipid interactions, was observed. It is possible that by having multiple patterns of interaction, VDAC1 can form homo- or hetero-oligomers not only with other VDAC1 protomers but also with other proteins such as VDAC2, VDAC3 and apoptosis-regulating proteins in the Bcl-2 family.

We hypothesized that this residual hydroxyapatite may serve as a receptor for chemical interaction with the functional monomer and, subsequently, contribute to adhesive performance in addition to micro-mechanical hybridization. We therefore chemically characterized the adhesive interaction of 3 functional monomers with synthetic hydroxyapatite, using x-ray photoelectron spectroscopy and atomic absorption spectrophotometry. We further characterized their interaction with dentin ultra-morphologically, using transmission electron microscopy. The monomer 10-methacryloxydecyl dihydrogen phosphate (10-MDP) readily adhered to hydroxyapatite. This bond appeared very stable, as confirmed by the low dissolution rate of its calcium salt in water. The bonding potential of 4-methacryloxyethyl trimellitic acid (4-MET) was substantially lower. The monomer 2-methacryloxyethyl phenyl hydrogen phosphate (phenyl-P) and its bond to hydroxyapatite did not appear to be hydrolytically stable. Besides self-etching dentin, specific functional monomers have additional chemical bonding efficacy that is expected to contribute to their adhesive potential to tooth tissue.

Abstract
The usefulness of emergent embolotherapy was evaluated in 17 patients with life-threatening hemorrhage from 18 ruptured splanchnic artery pseudoaneurysms. Complete hemostasis was obtained in 16 out of 17 patients by embolotherapy. Of the 12 initial embolization procedures with permanent embolic materials including stainless steel coils, microcoils, and Ivalon, complete cessation of bleeding was obtained in 11. On the other hand, 6 out of 9 initial embolization procedures with Gelfoam particles failed to halt bleeding, and additional embolization with permanent embolic materials was required. Emergent embolization with permanent embolic materials using superselective catheterization should be considered the initial treatment of choice for ruptured splanchnic artery pseudoaneurysms.

Abstract
Twenty-one patients with hepatocellular carcinoma (HCC) accompanied by extensive celiac artery stenosis or obstruction were treated by chemoembolization via the inferior pancreaticoduodenal artery (IPDA). The tip of the catheter was placed in the arteries in front of the confluence with the proper hepatic artery in 12 patients (group A: the proximal portion of the IPDA in 10, and common hepatic artery in 2), and in the proper hepatic artery or branches of it (group B) in 9 using a coaxial catheter system. Transient hyperamylasemia was observed in 10 of the 12 patients in group A and in 3 of the 9 patients in group B after chemoembolization. Splenic infarction developed in 8 patients in group A and in none in group B. Intrapancreatic fluid collection was present in 2 patients in group A following chemoembolization. No fatal complications were encountered. The 1-, 2-, and 3-year survival rates of the 10 patients in group A treated by only chemoembolization were 90, 57, and 23%, respectively (mean survival 780 days). The 1- and 2-year survival rates of 9 patients in group B were 85.8 and 85.8% (mean 879 days), respectively. Considering the severity of complications and the survival rates in groups A and B, chemoembolization by superselective catheterization into the hepatic artery via the IPDA is the treatment of choice. However, chemoembolization from the arteries in front of the confluence with the proper hepatic artery seems to be acceptable in cases of hypervascular HCC which fail to be superselectively catheterized.

Abstract
Emergent superselective embolization with a 3.0 F (1 mm) coaxial catheter and a steerable guidewire was performed in 27 patients with massive hemorrhage from a small-caliber splanchnic artery. Eight patients had intraperitoneal hemorrhage, 3 had hemobilia, 9 had gastric hemorrhage, and 7 had intestinal hemorrhage. Out of 27 patients, 7 had hemorrhage from a splanchnic artery pseudoaneurysm. Complete cessation of bleeding was obtained in all patients initially, but in 3 patients gastric hemorrhage recurred later. Otherwise, there was no rebleeding nor any major complication such as marked infarction of tissue or misplacement of embolic materials. This coaxial catheter system was highly reliable for achieving superselective catheterization in small-caliber arteries, minimizing the volume of infarcted tissue and allowing maximal preservation of splanchnic organic function. We conclude that this system represents a major advance in interventional radiology.

VDAC3 gating is activated by suppression of disulfide-bond formation between the N-terminal region and the bottom of the pore. BIOCHIMICA ET BIOPHYSICA ACTA-BIOMEMBRANES 2015; 1848:3188-96.

Abstract
The voltage-dependent anion channels (VDACs), VDAC1, VDAC2, and VDAC3, are pore-forming proteins that control metabolite flux between mitochondria and cytoplasm. VDAC1 and VDAC2 have voltage-dependent gating activity, whereas VDAC3 is thought to have weak activity. The aim of this study was to analyze the channel properties of all three human VDAC isoforms and to clarify the channel function of VDAC3. Bacterially expressed recombinant human VDAC proteins were reconstituted into artificial planar lipid bilayers and their gating activities were evaluated. VDAC1 and VDAC2 had typical voltage-dependent gating activity, whereas the gating of VDAC3 was weak, as reported. However, gating of VDAC3 was evoked by dithiothreitol (DTT) and S-nitrosoglutathione (GSNO), which are thought to suppress disulfide-bond formation. Several cysteine mutants of VDAC3 also exhibited typical voltage-gating. Our results indicate that channel gating was induced by reduction of a disulfide-bond linking the N-terminal region to the bottom of the pore. Thus, channel gating of VDAC3 might be controlled by redox sensing under physiological conditions.

Abstract
Diffuse pulmonary arteriovenous malformations (AVMs) are associated with a poor prognosis and the therapeutic strategy remains controversial. We describe a pediatric patient with diffuse pulmonary AVMs associated with hereditary hemorrhagic telangiectasia (HHT), who presented with two cerebral AVMs in the parietal and occipital lobes as well. Of note, successful bilateral lung transplantation not only improved the hypoxemia but also resulted in size reduction of the cerebral AVMs. Although it is essential to consider involvements other than pulmonary AVMs, especially brain AVMs, to decide the indication, lung transplantation can be a viable therapeutic option for patients with diffuse pulmonary AVMs and HHT.
