Objective: In the global phase 3 Study 309/KEYNOTE-775 (NCT03517449) at the first interim analysis, lenvatinib+pembrolizumab significantly improved progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) versus treatment of physician’s choice chemotherapy (TPC) in patients with previously treated advanced/recurrent endometrial cancer (EC). This exploratory analysis evaluated outcomes in patients enrolled in East Asia at the time of prespecified final analysis. Methods: Women ≥18 years with histologically confirmed advanced, recurrent, or metastatic EC with progressive disease after 1 platinum-based chemotherapy (2 if 1 given in neoadjuvant/ adjuvant setting) were enrolled. Patients were randomized 1:1 to lenvatinib 20 mg orally once daily plus pembrolizumab 200 mg intravenously every 3 weeks (≤35 cycles) or TPC (doxorubicin or paclitaxel). Primary endpoints were PFS per RECIST v1.1 by blinded independent central review and OS. No alpha was assigned for this subgroup analysis. Results: Among 155 East Asian patients (lenvatinib+pembrolizumab, n=77; TPC, n=78), median follow-up time (data cutoff: March 1, 2022) was 34.3 (range, 25.1–43.0) months.Hazard ratios (HRs) with 95% confidence intervals (CIs) for PFS (lenvatinib+pembrolizumab vs. TPC) were 0.74 (0.49–1.10) and 0.64 (0.44–0.94) in the mismatch repair proficient (pMMR) and all-comer populations, respectively. HRs (95% CI) for OS were 0.68 (0.45–1.02) and 0.61 (0.41–0.90), respectively. ORRs were 36% with lenvatinib+pembrolizumab and 22% with TPC (pMMR) and 39% and 21%, respectively (all-comers). Treatment-related adverse events occurred in 97% and 96% (grade 3–5, 74% and 72%), respectively. Conclusion Lenvatinib+pembrolizumab provided clinically meaningful benefit with manageable safety compared with TPC, supporting its use in East Asian patients with previously treated advanced/recurrent EC.

Objectives: Locomotive syndrome (LS) leads to reduced physical function and a high risk of becoming bedridden.Grip strength serves as an indicator of upper limb and overall physical function. Rheumatoid arthritis (RA) patients with reduced grip strength frequently show finger and wrist joint inflammation. The purpose of this study was to verify grip strength as an evaluation tool for physical function and LS in RA patients. Methods: As part of an ongoing multicenter observational study, 591 consecutive RA patients whose background information was available, including data for the 25-question Geriatric Locomotive Function Scale (GLFS-25) and grip strength, were examined. LS was defined as a GLFS-25 score ≥ 16 points. Finger and wrist joint inflammation were defined as tender or swollen joints. Results: Among the 591 patients, 244 (41.3%) patients had LS, and 167 (28.3%) were male. Receiver operating characteristic curve analysis yielded cut-off values of grip strength for LS of 24 kg (specificity 72.2%; sensitivity 62.7%) for males and 17 kg (specificity 65.7%; sensitivity 67.6%) for females. Multivariable logistic regression analysis revealed a significant association of grip strength with LS, even after adjusting for finger and wrist joint inflammation. Conclusions LS was significantly associated with grip strength, even after adjusting for the presence of finger and wrist joint inflammation. We recommend adopting grip strength measurement as a screening tool for evaluating LS and guiding interventions.

Objective: Bevacizumab maintenance therapy following platinum-based combination chemotherapy for metastatic, recurrent, or persistent cervical cancer is not recommended as standard therapy. This pilot study aimed to evaluate the efficacy and safety of bevacizumab maintenance therapy and the contribution of the platinum-free interval to the efficacy of subsequent chemotherapy for advanced cervical cancer. Methods: We retrospectively identified 115 patients with metastatic, recurrent, or persistent cervical cancer treated with platinum-paclitaxel chemotherapy plus bevacizumab at 7 institutions between 2015 and 2020. The primary endpoints were overall survival (OS) and progression-free survival (PFS) in patients who received bevacizumab maintenance therapy and those who did not. We also analyzed the adverse events associated with bevacizumab and survival time from the start of subsequent chemotherapy in both groups. Results: Following platinum-paclitaxel plus bevacizumab chemotherapy, 34 patients received bevacizumab maintenance therapy and 81 patients did not. Of the 115 patients, 56 received chemotherapy for subsequent relapse. Although bevacizumab maintenance therapy prolonged PFS (median of 16.0 months vs. 9.0 months, p=0.041), significant differences were not observed in OS (p=0.374). Furthermore, bevacizumab maintenance therapy did not prolong OS and PFS after the start of subsequent chemotherapy (p=0.663 and p=0.136, respectively). Bevacizumab maintenance therapy significantly increased hypertension (p=0.035) and proteinuria (p=0.005) but did not cause complications leading to death. Conclusion Bevacizumab single-maintenance therapy for advanced cervical cancer can be considered in selected cases, such as those with acceptable bevacizumab-related side effects. The outcomes of our study will likely contribute to decision-making regarding practical treatment strategies.

Background/Aims: Golimumab (GLM) is an anti-tumor necrosis factor-α drug approved for treating moderate-to-severe active ulcerative colitis (UC). A 52-week post-marketing surveillance (PMS) was initiated to evaluate its safety and effectiveness in patients with UC in Japan. We present an interim report of the ongoing PMS. Methods: Patients received 200 mg of subcutaneous GLM at week 0, 100 mg at week 2, and 100 mg 4 weekly thereafter. The safety analysis set included 392 patients with UC, and the effectiveness analysis set 387 patients. Safety and effectiveness were assessed at week 6. Results: Adverse drug reactions (ADRs) were reported in 8.2% (32/392) and serious ADRs in 4.6% (18/392). The most frequent ADRs were infection and infestation (3.3%), with herpes zoster being the most common. ADRs were significantly higher in patients with concomitant corticosteroid use (odds ratio [OR], 3.45; 95% confidence interval [CI], 1.40–9.68). No significant difference in ADR incidence was observed between patients aged ≥65 and <65 years (OR, 1.23; 95% CI, 0.35–3.47). Six-week effectiveness of GLM was confirmed by a decrease in the partial Mayo score (–2.3; 95% CI, –2.6 to –2.1) and C-reactive protein levels (–0.64; 95% CI, –0.92 to –0.36), including in the biologics-experienced population. Conclusions The safety and effectiveness of GLM at week 6 in a real-world setting were demonstrated in patients with UC in Japan. ADR patterns were consistent with previous reports with no new safety signals. Concomitant corticosteroid use may be associated with increased ADR incidence. The final results of the ongoing PMS are necessary for further evaluation.

Objective: The impact of systematic retroperitoneal lymphadenectomy (SRL) remains controversial in patients with advanced ovarian clear-cell carcinoma (CCC) who are optimally debulked. Methods: Between 1986 and 2017, a total of 3,227 women with epithelial ovarian carcinoma were analyzed in a multi-institutional study. Among them, 166 optimally debulked women with stage IIB–IV CCC were collected (residual tumor of <1 cm). All patients were divided into 2 groups: 1) Group I (n=112): underwent standard radical surgery with SRL, 2) Group II (n=54):underwent non-staging limited surgery. The pathological slides were assessed based on central pathological review. Oncologic outcomes were compared between the two groups using a propensity score (PS)-matching technique to adjust for various clinicopathologic factors. Results: The median follow-up duration of all surviving women was 52.8 (1.6–184.2) months.Overall, 88 patients (53.0%) experienced recurrence and 68 patients (41.0%) died of the disease. In the original cohort, the 5-year overall survival (OS) rates of groups I and II were 57.9 and 64.9%, respectively (log-rank p=0.415). In the PS-adjusted cohort, the 5-year OS rates were 64.9 and 58.8% in women in groups I and II, respectively (p=0.453). Furthermore, in the PS-matched cohort after adjustment for multiple clinicopathologic factors, there was no significant difference in OS between the 2 groups (group I vs. group II; hazard ratio=1.170;95% confidence interval=0.633–2.187; p=0.615). Conclusions This study suggests that the performance of SRL including radical surgery may not lead to a significant improvement in the oncologic outcome of advanced CCC patients with optimal cytoreduction.

BACKGROUND: Mutations in the quinolone resistance-determining regions (QRDRs) of Acinetobacter baumannii DNA gyrase (gyrA) and topoisomerase IV (parC) are linked to fluoroquinolone (FQ) resistance. We developed a mismatched PCR-restriction fragment length polymorphism (RFLP) assay to detect mutations in the gyrA and parC QRDRs associated with FQ resistance in A. baumannii. METHODS: Based on the conserved sequences of A. baumannii gyrA and parC, two primer sets were designed for mismatched PCR-RFLP to detect mutations in gyrA (codons 83 and 87) and parC (codons 80 and 84) by introducing an artificial restriction enzyme cleavage site into the PCR products. This assay was evaluated using 58 A. baumannii strains and 37 other Acinetobacter strains that have been identified by RNA polymerase β-subunit gene sequence analysis. RESULTS: PCR amplification of gyrA and parC was successful for all A. baumannii strains. In 11 FQ -susceptible strains, the gyrA and parC PCR products were digested by the selected restriction enzymes at the site containing gyrA (codons 83 and 87) and parC (codons 80 and 84). PCR products from 47 FQ-resistant strains containing mutations in gyrA and parC were not digested by the restriction enzymes at the site containing the mutation. As for the non-baumannii Acinetobacter strains, although amplification products for gyrA were obtained for 28 strains, no parC amplification product was obtained for any strain. CONCLUSIONS This assay specifically amplified gyrA and parC from A. baumannii and detected A. baumannii gyrA and parC mutations with FQ resistance.

BACKGROUND/AIMS: Inhibition of α4β7 integrin has been shown to be effective for induction and maintenance therapy in patients with ulcerative colitis (UC). We investigated the effects of varying doses of the α4β7 inhibitor abrilumab in Japanese patients with moderate-to-severe UC despite conventional treatments. METHODS: In this randomized, double-blind, placebo-controlled study, 45 UC patients were randomized to abrilumab 21 mg (n=11), 70 mg (n=12), 210 mg (n=9), or placebo (n=13) via subcutaneous (SC) injection for 12 weeks. The double-blind period was followed by a 36-week open-label period, in which all patients received abrilumab 210 mg SC every 12 weeks, and a 28-week safety follow-up period. The primary efficacy variable was clinical remission at week 8 (total Mayo score ≤2 points with no individual subscore >1 point). RESULTS: Clinical remission at week 8 was 4 out of 31 (12.9%) overall in the abrilumab groups versus 0 out of 13 in the placebo group (abrilumab 21 mg, 1/10 [10.0%]; 70 mg, 2/12 [16.7%]; 210 mg, 1/9 [11.1%]). In both the double-blind and open-label periods, fewer patients in the abrilumab groups experienced ≥1 adverse event compared with those in the placebo group. There were no cases of progressive multifocal leukoencephalopathy and no deaths. CONCLUSIONS: Abrilumab 70 mg and 210 mg yielded numerically better results in terms of clinical remission rate at Week 8 than placebo, with the 210 mg dose showing more consistent treatment effects. Abrilumab was well tolerated in Japanese patients with UC.

OBJECTIVE: The aim of this study was to investigate the clinical characteristics of young patients with stage I clear-cell carcinoma (CCC) and evaluate the prognostic factors and effects of fertility-sparing surgery (FSS) using propensity score (PS) adjustment. METHODS: We conducted a regional multi-institutional study between 1986 and 2017. Among 4,277 patients with ovarian tumor, clinical and pathological data of 103 fertile women with stage I unilateral CCC were collected. We evaluated survival and reproductive outcomes in these patients. Additionally, to analyze the effects of FSS, baseline imbalance between patients with and those without FSS was adjusted with an inverse probability of treatment weighting using PSs involving independent clinical variables. RESULTS: The mean patient age was 39.4 years, and the median follow-up period for surviving patients was 55.6 months. In multivariate analysis, stage IC2/IC3 (vs. IA/IC1) was the only independent prognostic factor for recurrence-free survival (RFS) and overall survival (OS). FSS was not associated with poorer prognosis when compared to the prognosis with non-preserving surgery with regard to both RFS and OS. No statistical difference in survival outcomes between FSS and other approaches was confirmed after PS adjustment. Among patients who underwent FSS, four deliveries with healthy neonates were noted without any gestational complications. CONCLUSION: FSS can be considered in stage I CCC, specifically in stage IA and IC1 patients who strongly desire to have children in the future. Further clinical research is needed to clarify the optimal application of FSS for CCC.
