Ontology highlight
ABSTRACT: Background
We aimed to explore the relative dose intensity (RDI) and post-regorafenib treatments in regorafenib therapy.Methods
The medical records of 38 patients treated with regorafenib between July 2017 and June 2019 at our institution were collected. The RDI of regorafenib for the first month (1M-RDI) was calculated.Results
The overall survival (OS) and progression-free survival (PFS) were 12.4 and 3.7 months. The objective response rate and disease control rate were 13.2% and 71.1%. The median total dose of regorafenib in the first month was 2080 mg (240-3360 mg), and the median 1M-RDI was 61.9% (7.1%-100%). Patients with 1M-RDI ? 50% showed significantly longer OS and PFS than patients with 1M-RDI < 50% (HR 0.19, 95% CI 0.08-0.48, p = 0.0004 and HR 0.2, 95% CI 0.08-0.52, p = 0.0008). A 1M-RDI ? 50% (HR 0.18, 95% CI 0.06-0.55, p = 0.002) and hand-foot skin reaction (HR 0.03, 95% CI 0.008-0.16, p < 0.0001) were independently associated with OS. Post-regorafenib therapies were performed in 19 (86.4%) of 22 patients who had stopped regorafenib due to disease progression.Conclusion
A 1M-RDI ? 50% is clinically significant. Post-regorafenib therapies are commonly performed in real-world practice.

Project description:In the RESORCE study, regorafenib after sorafenib therapy improved survival in patients with advanced hepatocellular carcinoma (HCC). In total, 88 patients with unresectable HCC who received sorafenib-regorafenib sequential therapy were enrolled. The objective response rate and disease control rate were 19.3% and 48.9%, respectively, for regorafenib therapy (median duration: 8.1 months). Median progression-free survival (PFS) after regorafenib therapy was 4.2 months (95% CI: 3.2-5.1). The median overall survival (OS; from initiation of either sorafenib or regorafenib) was not reached in this cohort. According to multivariate Cox regression analyses, albumin-bilirubin (ALBI) grade at the initiation of regorafenib therapy is an independent predictor of disease control, PFS, and OS. Moreover, the combination of ALBI grade 2 and an alpha-fetoprotein (AFP) level of ≥20 ng/mL was an independent predictor of PFS (hazard ratio (HR): 3.088, 95% CI: 1.704-5.595; p < 0.001) for regorafenib therapy, and OS for both regorafenib (HR: 3.783, 95% CI: 1.316-10.88; p = 0.014) and sorafenib-regorafenib sequential (HR: 4.603, 95% CI: 1.386-15.29; p = 0.013) therapy. A combination of ALBI grade and AFP level can be used to stratify patients with unresectable HCC by PFS and OS probability for sorafenib-regorafenib sequential therapy.

Project description:Background and aimsRegorafenib has demonstrated its survival benefit for unresectable hepatocellular carcinoma (uHCC) patients in a phase III clinical trial. We aimed to assess the efficacy and tolerability of regorafenib and the predictors of treatment outcomes in Taiwanese patients.MethodsWe analyzed the survival, best overall response, predictors of treatment outcomes, and safety for uHCC patients who had tumor progression on sorafenib therapy and received regorafenib as salvage therapy between March 2018 and November 2020.ResultsEighty-six patients with uHCC were enrolled (median age, 66.5 years; 76.7% male). The median regorafenib treatment duration was 4.0 months (95% confidence interval [CI], 3.6-4.6). The most frequently reported adverse events were hand-foot skin reaction (44.2%), diarrhea (36.0%), and fatigue (29.1%). No unpredictable toxicity was observed during treatment. The median overall survival (OS) with regorafenib was 12.4 months (95% CI, 7.8-17.0) and the median progression-free survival (PFS) was 4.2 months (95% CI, 3.7-4.7). Of 82 patients with regorafenib responses assessable, 4 patients (4.9%) achieved a partial response, and 33 (40.2%) had stable disease, leading to a disease control rate (DCR) of 45.1% (n = 37). Patients possessing baseline AFP < 400 ng/ml exhibited a markedly longer median OS, median PFS, and higher DCR compared with their counterparts (15.7 vs. 8.1 months, 4.6 vs. 3.7 months, 60.9% vs. 27.5%, respectively). Despite possessing high baseline AFP levels, patients with early AFP response (>10% reduction at 4 weeks or >20% reduction at 8 weeks after regorafenib administration) exhibited comparable treatment outcomes to those with baseline AFP < 400 ng/ml.ConclusionsThe results of this real-world study verified the tolerability and efficacy of regorafenib treatment for uHCC patients who failed prior sorafenib therapy, especially for those with lower baseline AFP levels or with early AFP response.

Project description:Regorafenib and nivolumab are drugs approved for second-line treatment of patients with hepatocellular carcinoma (HCC) after sorafenib failure. However, the effectiveness of regorafenib and nivolumab following sorafenib has not been directly compared. This study retrospectively evaluated 373 patients with HCC who were treated with regorafenib (n = 223) or nivolumab (n = 150) after sorafenib failure between July 2017 and February 2019. Progression-free survival (PFS; hazard ratio [HR], 0.85; 95% confidence interval [CI], 0.69-1.06; P = 0.150), time to progression (TTP; HR, 0.95; 95% CI, 0.77-1.19; P = 0.680), and overall survival (OS; HR, 0.83; 95% CI, 0.64-1.07; P = 0.154) did not differ significantly between groups of patients treated with regorafenib and nivolumab, findings consistently observed by multivariable-adjusted, propensity score-matched, and inverse probability treatment weighting (IPTW) analyses. However, the objective response rate was significantly higher in the nivolumab than in the regorafenib group (13.3% vs. 4.0%; P = 0.002). When the effectiveness of regorafenib and nivolumab was compared in nonprogressors to treatment, defined as patients who achieved complete response, partial response, or stable disease after first response evaluation, PFS (HR, 0.50; 95% CI, 0.33-0.75; P = 0.001), TTP (HR, 0.48; 95% CI, 0.31-0.73; P < 0.001), and OS (HR, 0.51; 95% CI, 0.31-0.87; P = 0.013) were significantly longer in the 59 nonprogressors to nivolumab than in the 104 nonprogressors to regorafenib, findings also observed by multivariable-adjusted and IPTW analyses. Conclusion: Survival outcomes in patients treated with regorafenib and nivolumab after sorafenib failure did not differ significantly. However, nivolumab may be more effective than regorafenib in nonprogressors.

Project description:AimsThere is a paucity of comparative data on the use of sorafenib and lenvatinib for unresectable hepatocellular carcinoma. We assessed the real-world treatment outcomes between using sorafenib and lenvatinib for unresectable hepatocellular carcinoma in the multiple molecular-targeted therapy era.Methods and resultsWe enrolled 386 patients treated with sorafenib or lenvatinib as the first-line therapy for unresectable hepatocellular carcinoma at multiple centers. Propensity score matching was performed to adjust for differences in baseline and tumor characteristics between the two groups. Propensity score matching identified 110 patients in each treatment group. The median overall survival was similar between lenvatinib and sorafenib (14.8 and 13.0 months, respectively; P = 0.352). The median progression-free survival was longer with lenvatinib than with sorafenib (7.6 and 3.9 months, respectively; P < 0.001). The overall response rate (P < 0.001) and disease control rate (P = 0.015), as defined by the modified Response Evaluation Criteria in Solid Tumors, were significantly better with lenvatinib than with sorafenib. The median overall survival was longer in patients who received subsequent treatment than in those who did not in the sorafenib group (23.1 and 5.7 months, respectively; P < 0.001), whereas the median overall survival with or without subsequent treatment did not differ significantly in the lenvatinib group (17.8 and 14.7 months, respectively; P = 0.439).ConclusionOverall survival with sorafenib and lenvatinib was not significantly different. However, patients who received subsequent treatments had longer overall survival than those who received only first-line treatment with sorafenib, whereas lenvatinib did not show this effect.

Project description:BackgroundEpidermal growth factor receptor-mutated (EGFR+) non-small-cell lung cancer (NSCLC) patients failing tyrosine kinase inhibitors (TKI) can benefit from next-line targeted therapies, but implementation is challenging.MethodsEGFR+ NSCLC patients treated with first/second-generation (1G/2G) TKI at our institution with a last follow-up after osimertinib approval (February 2016), were analyzed retrospectively, and the results compared with published data under osimertinib.ResultsA total of 207 patients received erlotinib (37%), gefitinib (16%) or afatinib (47%). The median age was 66 years, with a predominance of female (70%), never/light-smokers (69%). T790M testing was performed in 174/202 progressive cases (86%), positive in 93/174 (53%), and followed by osimertinib in 87/93 (94%). Among the 135 deceased patients, 94 (70%) received subsequent systemic treatment (43% chemotherapy, 39% osimertinib), while 30% died without, either before (4%) or after progression, due to rapid clinical deterioration (22%), patient refusal of further therapy (2%), or severe competing illness (2%). Lack of subsequent treatment was significantly (4.5x, p < 0.001) associated with lack of T790M testing, whose most frequent cause (in approximately 50% of cases) was also rapid clinical decline. Among the 127 consecutive patients with failure of 1G/2G TKI started after November 2015, 47 (37%) received osimertinib, with a median overall survival of 36 months versus 24 and 21 months for patients with alternative and no subsequent therapies (p = 0.003).ConclusionOsimertinib after 1G/2G TKI failure prolongs survival, but approximately 15% and 30% of patients forego molecular retesting and subsequent treatment, respectively, mainly due to rapid clinical deterioration. This is an important remediable obstacle to sequential TKI treatment for EGFR+ NSCLC. It pertains also to other actionable resistance mechanisms emerging under 1G/2G inhibitors or osimertinib, whose rate for lack of next-line therapy is similar (approximately 35% in the FLAURA/AURA3 trials), and highlights the need for closer monitoring alongside broader profiling of TKI-treated EGFR+ NSCLC in the future.

Project description:Atezolizumab plus bevacizumab was approved for patients with hepatocellular carcinoma (HCC). Although clinical trials have revealed its efficacy, the outcomes in the real-world clinical practice are unclear. We retrospectively evaluated the efficacy and safety of atezolizumab plus bevacizumab for HCC. This is a multicenter study conducted between November 2020 and March 2021. Among the 61 patients, 51 were assessed for progression-free survival (PFS), therapeutic response, and adverse events (AEs). The median PFS was 5.4 months. The objective response rate (ORR) was 35.3%. The disease control rate (DCR) was 86.3%. The incidence rates of AEs at any grade and grade >3 were 98.0% and 29.4%, respectively. The most frequent AE at any grade and grade >3 was hepatic disorder. In patients with a previous history of molecular targeted agent (MTA) or the degree of albumin-bilirubin (ALBI) grade, there were no significant differences in the PFS, ORR, DCR, and incidence rates of AEs. The study demonstrated that atezolizumab plus bevacizumab was effective and safe for patients with HCC even in the real-world setting including patients with a previous MTA history or other than ALBI grade 1.

Project description:Lenvatinib was recently approved as a first-line oral multikinase inhibitor for unresectable hepatocellular carcinoma (HCC). In this study, we aimed to compare the efficacy and safety of lenvatinib and sorafenib for the treatment of unresectable HCC in patients with prior failure of transarterial treatment. Between January 2019 and September 2020, 98 unresectable HCC patients treated with lenvatinib or sorafenib as salvage therapy were enrolled from five Korean university-affiliated hospitals. Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and disease control rate were calculated to assess the antitumor response. A total of 43 and 55 patients were treated with lenvatinib and sorafenib, respectively, as salvage therapy after the failure of transarterial treatments. The median PFS was 4.97 months in the lenvatinib group and 2.47 months in the sorafenib group (p = 0.001, log-rank test). The ORR was significantly higher in the lenvatinib group (25.6%) than in the sorafenib group (3.6%, p = 0.002). Use of lenvatinib over sorafenib (hazard ratio: 0.359, 95% confidence interval: 0.203-0.635, p < 0.001) was the most significant factor for a favorable PFS after the failure of transarterial treatments in all enrolled patients. For favorable OS, achieving objective response was the significant factor (hazard ratio 0.356, 95% confidence interval: 0.132-0.957, p = 0.041). There were no significant differences in the safety profile between the two groups. In this real-world study, lenvatinib was demonstrated to be more efficacious than sorafenib as a salvage therapy for transarterial treatments in unresectable HCC.

Project description:Background and aimsSequential therapy with molecular-targeted agents (MTAs) is considered effective for unresectable hepatocellular carcinoma (HCC) patients. This study purposed to evaluate the efficacy of sequential therapy with sorafenib (SORA) as a first-line therapy and to investigate the therapeutic impact of SORA in nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steato hepatitis (NASH)-related HCC.MethodsWe evaluated 504 HCC patients treated with SORA (Study-1). The times of administration for sorafenib from 2009 to 2015, 2016 to 2017, and 2018 and later were defined as the early-, mid-, and late-term periods, respectively. Among them, 180 HCC patients treated with SORA in addition to MTAs in the mid- and late-term periods were divided into groups based on disease etiology (NAFLD or NASH [n = 37] and viral or alcohol [n = 143]), and outcomes were compared after inverse probability weighting (IPW) (Study-2).ResultsOverall survival (OS) of HCC patients who received sequential MTA therapy after first-line SORA was significantly longer. The median survival times (MST) were 12.6 versus 17.6 versus 17.4 months in the early-term group, mid-term group, and the later-time group (early vs. mid, p = 0.014, early vs. later. p = 0.045), respectively. (Study-1). In Study-2, there was no significant differences in OS between the Virus/alcohol group and the NAFLD/NASH group in patients who received sequential therapy (MST was 23.4 and 27.0 months p = 0.173, respectively). The NAFLD or NASH, female sex, albumin-bilirubin (ALBI) grade 2b, and major Vp (Vp3/Vp4) were significant factors for OS treated with SORA.ConclusionsSequential therapy with SORA as the first-line treatment improved the prognosis of unresectable HCC patients and was effective regardless of HCC etiology.

Project description:IntroductionIn this literature review we evaluated the real-world clinical effectiveness of switching Japanese diabetic patients from their current insulin regimen to insulin degludec (IDeg).MethodsStudies were identified from Japanese Diabetes Society (JDS) abstracts (2014-2015) and PubMed (2012 onwards). Inclusion criteria were: Japanese population, >15 participants, and studies switching patients from basal or basal-bolus insulin regimens to IDeg. Randomized controlled trials and case reports were excluded. Weighted mean changes in safety and effectiveness endpoints were calculated using the number of patients in each study.ResultsIn total, 81 JDS abstracts and seven manuscripts met the search criteria, representing 4238 patients [1028 with type 1 diabetes (T1D), 602 with type 2 diabetes (T2D), 2608 with unspecified or mixed diabetes]. Glycated hemoglobin (HbA1c) was reported in 93% of studies, with an improvement in 84% of these (51% significant, 33% numerical), no change in 12%, and worsening in 4% (3% numerical, 1% significant). Across all studies, the weighted mean absolute change in HbA1c was -0.3% (-2.7 mmol/mol). Basal insulin dose was reported in 58% of studies and was lower in 60% of these (30% significant, 30% numerical), numerically unchanged in 26%, and higher in 14% (2% significant, 12% numerical). The weighted mean change in basal insulin dose was -4.8% and -3.0% for all studies and for studies with only significant results, respectively. The weighted mean change in basal dose based on all studies was -8.9, -5.5, and -2.9% for the T1D, T2D, and unspecified patient populations, respectively. Hypoglycemia was recorded in 31% of the studies. After switching treatment to IDeg, 55% of studies reported decreased hypoglycemia, 29% no change, and 16% an increase. Quality of life (QoL) was measured in 11% of studies, of which 82% reported improved QoL after switching, and 18% reported no change in QoL.ConclusionSwitching from a conventional basal insulin to IDeg has the potential to improve HbA1c with a lower insulin dose. Switching to IDeg may also provide a reduced risk of hypoglycemia and improvement in QoL.FundingNovo Nordisk.

Project description:To reduce the pro-angiogenic effects of sEH inhibition, a structure-activity relationship (SAR) study was performed by incorporating structural features of the anti-angiogenic multi-kinase inhibitor sorafenib into soluble epoxide hydrolase (sEH) inhibitors. The structural modifications of this series of molecules enabled the altering of selectivity towards the pro-angiogenic kinases C-RAF and vascular endothelial growth factor receptor-2 (VEGFR-2), while retaining their sEH inhibition. As a result, sEH inhibitors with greater potency against C-RAF and VEGFR-2 were obtained. Compound 4 (t-CUPM) possesses inhibition potency higher than sorafenib towards sEH but similar against C-RAF and VEGFR-2. Compound 7 (t-CUCB) selectively inhibits sEH, while inhibiting HUVEC cell proliferation, a potential anti-angiogenic property, without liver cancer cell cytotoxicity. The data presented suggest a potential rational approach to control the angiogenic responses stemming from sEH inhibition.
