RESUMEN

BACKGROUND: Immune checkpoint inhibitors (ICIs) and vascular endothelial growth factor receptor tyrosine kinase inhibitors are cornerstones of first-line treatment for advanced renal cell carcinoma; however, optimal treatment sequencing after progression is unknown. This study aimed to assess clinical outcomes of tivozanib-nivolumab versus tivozanib monotherapy in patients with metastatic renal cell carcinoma who have progressed following one or two lines of therapy in the post-ICI setting. METHODS: TiNivo-2 is a multicentre, randomised, open-label, phase 3 trial at 190 sites across 16 countries, in Australia, Europe, North America, and South America. Patients with advanced renal cell carcinoma and progression during or after one to two previous lines of therapy (including one ICI) were randomised 1:1 to tivozanib (0·89 mg per day, orally) plus nivolumab (480 mg every 4 weeks, intravenously) or tivozanib (1·34 mg per day, orally). Randomisation was stratified by immediate previous therapy (ICI or non-ICI) and International Metastatic Renal Cell Carcinoma Database Consortium risk category. The primary endpoint was progression-free survival (PFS), defined as the time from randomisation to first documentation of objective progressive disease according to RECIST 1·1 or death from any cause, whichever came first, by independent radiology review. Efficacy was evaluated in the intention-to-treat population, and safety was assessed in patients who received one or more doses of the study drug. This trial was registered on ClinicalTrials.gov (NCT04987203) and is active and not recruiting. FINDINGS: From Nov 4, 2021, to June 16, 2023, 343 patients were randomly assigned to tivozanib-nivolumab (n=171) or tivozanib monotherapy (n=172). Median follow-up was 12·0 months. Median PFS was 5·7 months (95% CI 4·0-7·4) with tivozanib-nivolumab and 7·4 months (5·6-9·2) with tivozanib monotherapy (hazard ratio 1·10, 95% CI 0·84-1·43; p=0·49). Among those with an ICI as their immediate previous therapy (n=244), median PFS was 7·4 months (95% CI 5·6-9·6) with tivozanib-nivolumab and 9·2 months (7·4-10·0) with tivozanib monotherapy. With non-ICIs as the most recent therapy, lower median PFS was observed, with no difference between groups (tivozanib-nivolumab 3·7 months [95% CI 2·7-5·4] and with tivozanib monotherapy 3·7 months [1·9-7·2]). Serious adverse events occurred in 54 (32%) of 168 patients receiving tivozanib-nivolumab and 64 (37%) of 171 patients receiving tivozanib monotherapy. One (<1%) treatment-related death occurred (tivozanib group). INTERPRETATION: These data further support that ICI rechallenge should be discouraged in patients with advanced renal cell carcinoma. Furthermore, these data suggest that tivozanib monotherapy has efficacy in the post-ICI setting. FUNDING: Aveo Pharmaceuticals.

RESUMEN

BACKGROUND: Standard therapy for advanced endometrial cancer after failure of platinum-based chemotherapy remains unclear. METHODS: In this phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with advanced endometrial cancer who had previously received at least one platinum-based chemotherapy regimen to receive either lenvatinib (20 mg, administered orally once daily) plus pembrolizumab (200 mg, administered intravenously every 3 weeks) or chemotherapy of the treating physician's choice (doxorubicin at 60 mg per square meter of body-surface area, administered intravenously every 3 weeks, or paclitaxel at 80 mg per square meter, administered intravenously weekly [with a cycle of 3 weeks on and 1 week off]). The two primary end points were progression-free survival as assessed on blinded independent central review according to the Response Evaluation Criteria in Solid Tumors, version 1.1, and overall survival. The end points were evaluated in patients with mismatch repair-proficient (pMMR) disease and in all patients. Safety was also assessed. RESULTS: A total of 827 patients (697 with pMMR disease and 130 with mismatch repair-deficient disease) were randomly assigned to receive lenvatinib plus pembrolizumab (411 patients) or chemotherapy (416 patients). The median progression-free survival was longer with lenvatinib plus pembrolizumab than with chemotherapy (pMMR population: 6.6 vs. 3.8 months; hazard ratio for progression or death, 0.60; 95% confidence interval [CI], 0.50 to 0.72; P<0.001; overall: 7.2 vs. 3.8 months; hazard ratio, 0.56; 95% CI, 0.47 to 0.66; P<0.001). The median overall survival was longer with lenvatinib plus pembrolizumab than with chemotherapy (pMMR population: 17.4 vs. 12.0 months; hazard ratio for death, 0.68; 95% CI, 0.56 to 0.84; P<0.001; overall: 18.3 vs. 11.4 months; hazard ratio, 0.62; 95% CI, 0.51 to 0.75; P<0.001). Adverse events of grade 3 or higher occurred in 88.9% of the patients who received lenvatinib plus pembrolizumab and in 72.7% of those who received chemotherapy. CONCLUSIONS: Lenvatinib plus pembrolizumab led to significantly longer progression-free survival and overall survival than chemotherapy among patients with advanced endometrial cancer.

RESUMEN

BACKGROUND: Novel treatments are needed for patients with advanced, triple-negative breast cancer (TNBC) that progresses or recurs after first-line treatment with chemotherapy. The authors report results from the TNBC cohort of the multicohort, open-label, single-arm, phase 2 LEAP-005 study of lenvatinib plus pembrolizumab in patients with advanced solid tumors (ClinicalTrials.gov identifier NCT03797326). METHODS: Eligible patients had metastatic or unresectable TNBC with disease progression after one or two lines of therapy. Patients received lenvatinib (20 mg daily) plus pembrolizumab (200 mg every 3 weeks; up to 35 cycles). The primary end points were the objective response rate according to Response Evaluation Criteria in Solid Tumors, version 1.1, and safety (adverse events graded by the National Cancer Institute's Common Terminology Criteria for Adverse Events, version 4.0). Duration of response, progression-free survival, and overall survival were secondary end points. RESULTS: Thirty-one patients were enrolled. The objective response rate by investigator assessment was 23% (95% confidence interval [CI], 10%-41%). Overall, the objective response rate by blinded independent central review (BICR) was 32% (95% CI, 17%-51%); and, in patients who had programmed cell death ligand 1 combined positive scores ≥10 (n = 8) and <10 (n = 22), the objective response rate was 50% (95% CI, 16%-84%) and 27% (95% CI, 11%-50%), respectively. The median duration of response by BICR was 12.1 months (range, from 3.0+ to 37.9+ months). The median progression-free survival by BICR was 5.1 months (95% CI, 1.9-11.8 months) and the median overall survival was 11.4 months (95% CI, 4.1-21.7 months). Treatment-related adverse events occurred in 94% of patients (grade 3, 52%; grade 4, 0%). One patient died due to a treatment-related adverse event of subarachnoid hemorrhage. CONCLUSIONS: The combination of lenvatinib plus pembrolizumab demonstrated antitumor activity with a manageable safety profile in patients with previously treated, advanced TNBC.

RESUMEN

BACKGROUND: Uterine fibroids are a common cause of heavy menstrual bleeding and pain. Treatment with the combination of relugolix (an oral gonadotropin-releasing hormone-receptor antagonist), estradiol, and norethindrone acetate, administered once daily, may have efficacy in women with uterine fibroids and heavy bleeding while avoiding hypoestrogenic effects. METHODS: We conducted two replicate international, double-blind, 24-week, phase 3 trials involving women with fibroid-associated heavy menstrual bleeding. Participants were randomly assigned in a 1:1:1 ratio to receive once-daily placebo, relugolix combination therapy (40 mg of relugolix, 1 mg of estradiol, and 0.5 mg of norethindrone acetate), or delayed relugolix combination therapy (40 mg of relugolix monotherapy, followed by relugolix combination therapy, each for 12 weeks). The primary efficacy end point in each trial was the percentage of participants with a response (volume of menstrual blood loss <80 ml and a ≥50% reduction in volume from baseline) in the relugolix combination therapy group, as compared with the placebo group. Key secondary end points were amenorrhea, volume of menstrual blood loss, distress from bleeding and pelvic discomfort, anemia, pain, fibroid volume, and uterine volume. Safety and bone mineral density were assessed. RESULTS: A total of 388 women in trial L1 and 382 in trial L2 underwent randomization. A total of 73% of the participants in the relugolix combination therapy group in trial L1 and 71% of those in trial L2 had a response (primary end point), as compared with 19% and 15%, respectively, of those in the placebo groups (P<0.001 for both comparisons). Both relugolix combination therapy groups had significant improvements, as compared with the placebo groups, in six of seven key secondary end points, including measures of menstrual blood loss (including amenorrhea), pain, distress from bleeding and pelvic discomfort, anemia, and uterine volume, but not fibroid volume. The incidence of adverse events was similar with relugolix combination therapy and placebo. Bone mineral density was similar with relugolix combination therapy and placebo but decreased with relugolix monotherapy. CONCLUSIONS: Once-daily relugolix combination therapy resulted in a significant reduction in menstrual bleeding, as compared with placebo, and preserved bone mineral density in women with uterine fibroids.

RESUMEN

BACKGROUND: Lenvatinib in combination with pembrolizumab or everolimus has activity against advanced renal cell carcinoma. The efficacy of these regimens as compared with that of sunitinib is unclear. METHODS: In this phase 3 trial, we randomly assigned (in a 1:1:1 ratio) patients with advanced renal cell carcinoma and no previous systemic therapy to receive lenvatinib (20 mg orally once daily) plus pembrolizumab (200 mg intravenously once every 3 weeks), lenvatinib (18 mg orally once daily) plus everolimus (5 mg orally once daily), or sunitinib (50 mg orally once daily, alternating 4 weeks receiving treatment and 2 weeks without treatment). The primary end point was progression-free survival, as assessed by an independent review committee in accordance with Response Evaluation Criteria in Solid Tumors, version 1.1. Overall survival and safety were also evaluated. RESULTS: A total of 1069 patients were randomly assigned to receive lenvatinib plus pembrolizumab (355 patients), lenvatinib plus everolimus (357), or sunitinib (357). Progression-free survival was longer with lenvatinib plus pembrolizumab than with sunitinib (median, 23.9 vs. 9.2 months; hazard ratio for disease progression or death, 0.39; 95% confidence interval [CI], 0.32 to 0.49; P<0.001) and was longer with lenvatinib plus everolimus than with sunitinib (median, 14.7 vs. 9.2 months; hazard ratio, 0.65; 95% CI, 0.53 to 0.80; P<0.001). Overall survival was longer with lenvatinib plus pembrolizumab than with sunitinib (hazard ratio for death, 0.66; 95% CI, 0.49 to 0.88; P = 0.005) but was not longer with lenvatinib plus everolimus than with sunitinib (hazard ratio, 1.15; 95% CI, 0.88 to 1.50; P = 0.30). Grade 3 or higher adverse events emerged or worsened during treatment in 82.4% of the patients who received lenvatinib plus pembrolizumab, 83.1% of those who received lenvatinib plus everolimus, and 71.8% of those who received sunitinib. Grade 3 or higher adverse events occurring in at least 10% of the patients in any group included hypertension, diarrhea, and elevated lipase levels. CONCLUSIONS: Lenvatinib plus pembrolizumab was associated with significantly longer progression-free survival and overall survival than sunitinib.

RESUMEN

BACKGROUND: Alpha-fetoprotein elevated gastric cancer (AFPGC) got growing interests for its aggressive nature and unfavorable prognosis. Here, a phase 1 dose escalation study was conducted to evaluate safety and efficacy of zimberelimab (GLS-010, anti-PD-1) plus lenvatinib and chemotherapy (XELOX) as the first-line treatment for AFPGC. METHODS: Histologically confirmed HER2-negative, advanced GC patients with elevated serum AFP level (≥ 20 ng/ml) were screened. Using a 3 + 3 dose escalation design, patients were administered varying doses of lenvatinib (12, 16, 20 mg) with GLS-010 and XELOX. The primary endpoints were safety and determination of recommended phase II dose (RP2D). Secondary endpoints included overall response rate (ORR), progression-free survival (PFS) and disease control rate. RESULTS: Nine patients were enrolled with no dose-limiting toxicities observed. Most frequent treatment-related AEs were fatigue (55.6%), hand-foot syndrome (55.6%) and rash (55.6%), and no grade ≥ 4 AEs were reported. All patients exhibited disease control with ORR reaching 33.3%. The median PFS and OS reached 7.67 months (95% CI 4.07-11.27) and 13.17 months (95% CI 2.78-23.56), respectively. Serum AFP level was found correlated with therapeutic responses. Further 16s rRNA sequencing analysis demonstrated altered gut microbiota with elevated abundance of Lachnospiraceae bacterium-GAM79 and Roseburia hominis A2-183. CONCLUSIONS: GLS-010 plus lenvatinib and XELOX demonstrated a manageable safety profile with promising efficacy for AFPGC. With RP2D of lenvatinib determined as 16 mg, further expansion cohort is now ongoing. Translational investigation suggested that serum AFP can be indictive for therapeutic responses and certain microbiota species indicating favorable responses to immunotherapy was elevated after the combinational treatment.

RESUMEN

BACKGROUND: Treatment options for advanced intrahepatic cholangiocarcinoma (ICC) are currently limited. Chemo-containing regimens are the mainstay treatments but associated with notable toxicity, poor tolerance, and reduced compliance, necessitating exploration of alternative therapies. Lenvatinib plus PD-1 inhibitors has shown substantial clinical activity in preliminary studies. This study aimed to assess the effectiveness and safety of lenvatinib plus toripalimab (a novel PD-1 antibody) as chemo-free therapy in advanced ICC. METHODS: This retrospective study included consecutive advanced ICC patients receiving lenvatinib plus toripalimab between February 2019 and December 2023. The main outcomes were overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and safety. Prognostic factors and exploratory analyses for genetic alternations were also conducted. RESULTS: A total of 78 patients were included, with a median follow-up of 25.9 months. Median OS and PFS were 11.3 (95% CI: 9.5-13.1) and 5.4 (95% CI: 3.8-7.0) months, respectively. ORR was 19.2% and DCR was 75.6%. The incidence of grade 3 or 4 adverse events (AEs) was 50.0%, with no grade 5 AEs reported. Patients with normal baseline CA19-9 levels exhibited a higher ORR (p = 0.011), longer PFS (11.5 versus 4.6 months; HR 0.47; p=0.005), and OS (21.0 versus 9.7 months; HR 0.43; p=0.003). The presence of IDH1 mutations correlated with increased ORR (60.0% versus 8.9%, p=0.016). CONCLUSION: Lenvatinib plus toripalimab represents an effective and well-tolerated chemo-free therapeutic option for advanced ICC. Baseline CA19-9 levels and IDH1 mutations may serve as predictive treatment-related biomarkers.

RESUMEN

BACKGROUND: Lenvatinib, programmed cell death 1 (PD-1) antibodies, and gemcitabine and oxaliplatin (GEMOX) chemotherapy have shown significant antitumor activity as first-line therapy against biliary tract cancer. This study evaluated their efficacy and safety as non-first-line therapy in advanced gallbladder cancer (GBC). METHODS: Patients with advanced GBC who received lenvatinib combined with anti-PD-1 antibodies and GEMOX chemotherapy as a non-first-line therapy were retrospectively analyzed. The primary endpoints were overall survival (OS) and progression-free survival (PFS), and the secondary endpoints were objective response rate (ORR) and safety. RESULTS: A total of 36 patients with advanced GBC were included in this study. The median follow-up time was 11.53 (95% confidence interval (CI): 2.2-20.9) months, and the ORR was 36.1%. The median OS and PFS were 15.1 (95% CI: 3.2-26.9) and 6.1 (95% CI: 4.9-7.2) months, respectively. The disease control rate (DCR) and clinical benefit rate (CBR) were 75% and 61.1%, respectively. Subgroup analysis demonstrated that patients with programmed cell death-ligand 1 (PD-L1) expression had significantly longer PFS and OS than those without PD-L1 expression. Additionally, patients with a neutrophil-lymphocyte ratio (NLR) < 5.57 had a longer OS than those with an NLR ≥ 5.57. All patients experienced adverse events (AEs), with 61.1% experiencing grade 3 or 4 AEs, including myelosuppression (13.9%) and fatigue (13.3%), alanine transaminase or aspartate transaminase levels (8.3%), and diarrhea (8.3%). No grade 5 AEs were reported. CONCLUSION: Anti-PD-1 antibodies combined with lenvatinib and GEMOX chemotherapy are effective and well-tolerated as a non-first-line therapy in advanced GBC. PD-L1 expression and baseline NLR may potentially predict treatment efficacy.

RESUMEN

BACKGROUND: Lenvatinib is widely used in treatment of unresectable hepatocellular carcinoma (uHCC), but the benefit of its combination with immunotherapy needs to be verified. This study evaluated the efficacy and safety of tislelizumab plus lenvatinib in systemic treatment-naïve patients with uHCC. METHODS: In this multicenter, single-arm, phase 2 study, systemic treatment-naïve patients with uHCC received tislelizumab 200 mg every three weeks plus lenvatinib (bodyweight ≥ 60 kg: 12 mg; < 60 kg: 8 mg; once daily). Dose-limiting toxicities (DLTs) were evaluated in safety run-in phase to determine whether to enter the expansion phase. The primary endpoint was objective response rate (ORR) assessed by independent review committee (IRC) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1). Based on Simon's two-stage design, > 6 responders were needed in stage 1 (n = 30) to continue the study, and ≥ 18 responders were needed by the end of stage 2 (n = 60) to demonstrate statistical superiority to a historical control of lenvatinib monotherapy. RESULTS: Sixty-four patients were enrolled. No DLTs were reported. The study achieved statistical superiority (p = 0.0003) with 23 responders assessed by IRC per RECIST v1.1 in the first 60 patients of the efficacy evaluable analysis set (n = 62). After a median follow-up of 15.7 months, confirmed ORR and disease control rate were 38.7% (24/62, 95% confidence interval [CI], 26.6-51.9) and 90.3% (56/62, 95% CI, 80.1-96.4), respectively. Median progression-free survival was 8.2 months (95% CI, 6.8-not evaluable). Overall survival rate at 12 months was 88.6% (95% CI, 77.7-94.4). Grade ≥ 3 treatment-related adverse events occurred in 18 (28.1%) patients. CONCLUSIONS: Tislelizumab plus lenvatinib demonstrated promising antitumor activity with favourable tolerability as first-line therapy for patients with uHCC.

RESUMEN

The aim of the present study was to determine whether the trough plasma concentrations (C0) of regorafenib and its metabolites, the N-oxide metabolite (M-2) and the desmethyl N-oxide metabolite (M-5), in 21 patients receiving regorafenib therapy were affected by albumin-bilirubin (ALBI) grade. Regorafenib was administered at dosages ranging from 40 to 160 mg once daily on a 3-week-on, 1-week-off cycle. C0 values of regorafenib and its major metabolites were measured by high-performance liquid chromatography on day 8 after treatment initiation. The C0 values of regorafenib and metabolites M-2 and M-5 were significantly lower in patients with ALBI grade 2 as compared with grade 1 (P = 0.023, 0.003 and 0.017, respectively). The total C0 of regorafenib and its metabolites was significantly higher in ALBI grade 1 patients relative to grade 2 (3.489 µg/mL vs. 1.48 µg/mL; P = 0.009). The median relative dose intensity (RDI) of patients categorized as ALBI grade 2 was significantly lower than that of grade 1 patients (21.9% vs. 62.9%; P = 0.006). In 15 colorectal cancer patients among the total 21 patients, patients with ALBI grade 2 (n = 9) had a significantly shorter median overall survival time than patients with grade 1 (n = 6; P = 0.013). Administering a low dose of regorafenib to patients with ALBI grade 2 reduces the RDI of regorafenib and lowers treatment efficacy, as an appropriate C0 of regorafenib is not maintained. Monitoring the C0 of regorafenib regularly is necessary to guide dose adjustment.

RESUMEN

This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child-Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child-Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study.

RESUMEN

The oral multikinase inhibitors sorafenib and lenvatinib are currently available as first-line treatment for patients with unresectable or metastatic thyroid cancer. However, treatment options for patients who are refractory to these multikinase inhibitors are limited. This study aimed to evaluate the safety and efficacy of rechallenged lenvatinib after failure of both lenvatinib and sorafenib in patients with metastatic thyroid cancer in the real-world clinical practice. We retrospectively reviewed the data of consecutive 16 patients with metastatic thyroid cancer who received lenvatinib as a rechallenge after failure of initial lenvatinib and sorafenib treatment at Shizuoka Cancer Center between 2016 and 2023. Of these, the initial lenvatinib was discontinued in 12 patients owing to progressive disease, in 3 patients owing to adverse events, and in 1 patient owing to both. The overall response rate was 6.7%, and disease control was achieved by rechallenge with lenvatinib in all patients with the target lesions. The median progression free survival after rechallenging with lenvatinib was 15.0 months. No new signs of toxicity were observed after rechallenging with lenvatinib. Our findings suggest that rechallenge with lenvatinib after failure of both lenvatinib and sorafenib showed manageable safety and modest efficacy in patients with metastatic thyroid cancer in clinical practice. The strategy of lenvatinib rechallenge may provide an alternative option for patients with no targetable driver genes or when selective kinase inhibitors are not indicated.

RESUMEN

INTRODUCTION: The treatment of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) and lenvatinib individually has shown favorable outcomes, but there is currently no meta-analysis based on randomized controlled trials (RCTs) to investigate the efficacy and safety of this combined treatment for HCC. The aim of this study was to identify the efficacy and safety of TACE plus lenvatinib for the treatment of HCC. METHODS: A systematic search of MEDLINE (via PubMed), the Cochrane Library, EMBASE, and the Web of Science was conducted on July 31, 2023. RCTs evaluating the efficacy and safety of TACE in combination with lenvatinib for the treatment of HCC were included. The risk of bias in the included studies was assessed using the Risk of Bias 2 tool. Outcome measures such as objective response rate (ORR), complete remission (CR), progression-free survival (PFS), overall survival (OS), and safety parameters were extracted from the included studies. Binary outcomes were analyzed using odds ratio (OR), risk ratio, or hazard ratio (HR), while continuous variables were analyzed using mean difference (MD) or standardized MD in RStudio. The quality of the evidence was graded using the GRADE approach. Heterogeneity was considered significant when the I-squared was 50% or less. RESULTS: Five RCTs involving 638 patients were included. The meta-analysis revealed that patients in the TACE plus lenvatinib group had a significantly higher mean ORR compared to the control group (OR: 3.65, 95% confidence interval [CI]: 2.50-5.32, fixed-effects model; OR: 3.58, 95% CI: 2.45-5.24, random-effects model, I2 = 0, moderate quality). Specifically, 40.9% of patients in the TACE plus lenvatinib group achieved a PR, which was significantly higher than the control group (OR: 3.51, 95% CI: 2.41-5.13, fixed-effects model; OR: 3.46, 95% CI: 2.36-5.07, random-effects model, I2 = 0, moderate quality). The HR for OS was 0.47 (95% CI: 0.35-0.62, fixed-effects model and random-effects model, I2 = 0, moderate quality). The meta-analysis revealed that the TACE plus lenvatinib group had a significantly higher total adverse effects rate than the control group (OR: 1.86, 95% CI: 1.01-3.43, fixed-effects model; OR: 1.85, 95% CI: 1.00-3.43, random-effects model, I2 = 0, moderate quality). CONCLUSION: Our study suggests that the combination of TACE and lenvatinib in the treatment of HCC has shown promising results, with extended OS and improved ORR.

RESUMEN

BACKGROUND: The randomized, dose-optimization, open-label ReDOS study in US patients with metastatic colorectal cancer (CRC) showed that, compared with a standard dosing approach, initiating regorafenib at 80 mg/day and escalating to 160 mg/day depending on tolerability increased the proportion of patients reaching their third treatment cycle and reduced the incidence of adverse events without compromising efficacy. Subsequently, the ReDOS dose-escalation strategy was included as an alternative regorafenib dosing option in the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines. A retrospective analysis was conducted using a US claims database to assess whether inclusion of this dose-escalation strategy in NCCN Guidelines has influenced the use of flexible dosing in routine US clinical practice, and to describe clinical outcomes pre- and post-inclusion in NCCN Guidelines. METHODS: Patients with CRC in the Optum's de-identified Clinformatics® Data Mart database initiating regorafenib for the first time between January 2016 and June 2020 were stratified based on whether they initiated regorafenib pre- or post-inclusion of ReDOS in NCCN Guidelines, and in two groups: flexible dosing (< 160 mg/day; < 84 tablets in the first treatment cycle) and standard dosing (160 mg/day; ≥ 84 tablets in the first treatment cycle). The primary endpoints were the proportion of patients who initiated their third treatment cycle and the mean number of treatment cycles per group. RESULTS: 703 patients initiated regorafenib during the study period, of whom 310 (44%) initiated before and 393 (56%) initiated after inclusion of ReDOS in NCCN Guidelines. After inclusion in the guidelines, the proportion of patients who received flexible dosing increased from 21% (n = 66/310) to 45% (n = 178/393), the proportion who received standard dosing decreased from 79% (n = 244/310) to 55% (n = 215/393), the proportion who initiated their third treatment cycle increased from 36% (n = 113/310) to 46% (n = 179/393), and the mean (standard deviation) number of treatment cycles increased from 2.6 (2.9) to 3.2 (3.1). CONCLUSIONS: Following inclusion of ReDOS in NCCN Guidelines, real-world data suggest that US clinicians have markedly increased use of flexible dosing in clinical practice, potentially maximizing clinical benefits and safety outcomes for patients with metastatic CRC receiving regorafenib.

RESUMEN

BACKGROUNDS: To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined Lenvatinib plus Camrelizumab (TLC) in unresectable hepatocellular carcinoma (uHCC) with those of TACE alone . METHODS: A retrospective analysis was performed on 222 patients with uHCC who were treated between September 2013 and Jun 2023. One group received TACE + lenvatinib + camrelizumab (TLC) (n = 97) and another group received TACE alone (n = 151). Efficacy and safety were compared after propensity score matching between the TLC and TACE groups. RESULTS: After propensity matching, the TLC group had higher objective response rate (ORR) (88.6% vs. 28.6%, P < 0.001), disease control rate (DCR) (94.3%% vs. 72.9%, P < 0.001), and conversion rates before and after propensity matching were 44.1% and 41.4%, respectively, compared with the TACE group. The median progression free survival (PFS) was longer in the TLC group than in the TACE group (12.7 vs. 6.1 months, P = 0.005). The median overall survival (OS) was longer in the TLC group than in the TACE group (19.4 vs. 13.0 months, P = 0.023). Cox multivariate analysis with different modes of adjustment showed that treatment was an independent influencing factor of PFS and OS. The interaction analysis showed that cirrhosis and Child-Pugh stage an interactive role in the PFS of different treatment. Decreased AFP after treatment portends higher ORR and DCR. CONCLUSION: TACE combined Lenvatinib plus Camrelizumab regimen was safe and superior to TACE alone in improving PFS, OS, and tumor response rates for unresectable recurrent HCC patients.

RESUMEN

BACKGROUND: The combination of targeted therapy and immunotherapy has improved the clinical outcomes of unresectable hepatocellular Carcinoma (HCC). However, the overall prognosis remains suboptimal. This study aims to evaluate the efficacy and safety of a novel combination of radiofrequency ablation (RFA) with lenvatinib plus sintilimab in unresectable HCC. METHODS: In this retrospective study, patients diagnosed with unresectable HCC were included and divided into two cohorts: RFA combined with lenvatinib plus sintilimab (R-L-S group) and lenvatinib plus sintilimab (L-S group). The primary efficacy endpoints were objective response rate (ORR) and progression free survival (PFS). Adverse events were analyzed to assess the safety profiles. RESULTS: The median follow-up periods for the entire cohort were 14.0 months. The R-L-S group (n = 60) had a significantly higher ORR than those with L-S alone (n = 62) (40.0% vs. 20.9%; p = 0.022). Moreover, patients in the R-L-S group had improved median PFS (12 vs. 8 months; p = 0.013) and median overall survival (24 vs. 18 months; p = 0.037), as compared with lenvatinib and sintilimab alone. No significant difference in treatment related adverse event (TRAE) of any grade between the two groups. The most common TRAEs of grade ≥ 3 were fatigue 10.0% (6/60) and hand-foot skin reaction 10.0% (6/60) in the R-L-S group and hand-foot skin reaction 11.3% (7/62) in the L-S group. CONCLUSION: In unresectable HCC patients, the incorporation of RFA to lenvatinib plus sintilimab demonstrated improved efficacy without compromising safety compared with lenvatinib plus sintilimab alone.

RESUMEN

BACKGROUND: Heterogeneity of hepatocellular carcinoma (HCC) presents significant challenges for therapeutic strategies and necessitates combinatorial treatment approaches to counteract suppressive behavior of tumor microenvironment and achieve improved outcomes. Here, we employed cytokines to induce memory-like behavior in natural killer (NK) cells, thereby enhancing their cytotoxicity against HCC. Additionally, we evaluated the potential benefits of combining sorafenib with this newly developed memory-like NK cell (pNK) immunochemotherapy in a preclinical model. METHODS: HCC tumors were grown in SD rats using subcapsular implantation. Interleukin 12/18 cytokines were supplemented to NK cells to enhance cytotoxicity through memory activation. Tumors were diagnosed using MRI, and animals were randomly assigned to control, pNK immunotherapy, sorafenib chemotherapy, or combination therapy groups. NK cells were delivered locally via the gastrointestinal tract, while sorafenib was administered systemically. Therapeutic responses were monitored with weekly multi-parametric MRI scans over three weeks. Afterward, tumor tissues were harvested for histopathological analysis. Structural and functional changes in tumors were evaluated by analyzing MRI and histopathology data using ANOVA and pairwise T-test analyses. RESULTS: The tumors were allowed to grow for six days post-cell implantation before treatment commenced. At baseline, tumor diameter averaged 5.27 mm without significant difference between groups (p = 0.16). Both sorafenib and combination therapy imposed greater burden on tumor dimensions compared to immunotherapy alone in the first week. By the second week of treatment, combination therapy had markedly expanded its therapeutic efficacy, resulting in the most significant tumor regression observed (6.05 ± 1.99 vs. 13.99 ± 8.01 mm). Histological analysis demonstrated significantly improved cell destruction in the tumor microenvironment associated with combination treatment (63.79%). Interestingly, we observed fewer viable tumor regions in the sorafenib group (38.9%) compared to the immunotherapy group (45.6%). Notably, there was a significantly higher presence of NK cells in the tumor microenvironment with combination therapy (34.79%) compared to other groups (ranging from 2.21 to 26.50%). Although the tumor sizes in the monotherapy groups were similar, histological analysis revealed a stronger response in pNK cell immunotherapy group compared to the sorafenib group. CONCLUSIONS: Experimental results indicated that combination therapy significantly enhanced treatment response, resulting in substantial tumor growth reduction in alignment with histological analysis.

RESUMEN

OBJECTIVES: The phase 2, multicohort, open-label LEAP-005 study evaluated lenvatinib plus pembrolizumab in patients with previously treated advanced solid tumors. We report outcomes from the ovarian cancer cohort. METHODS: Eligible patients had metastatic/unresectable ovarian cancer and had received 3 previous lines of therapy. Patients received lenvatinib 20 mg/day plus pembrolizumab 200 mg every 3 weeks. Treatment continued until progression, unacceptable toxicity, or (for pembrolizumab) completion of 35 cycles. Primary endpoints were objective response rate (ORR) per RECIST version 1.1 and safety. Secondary endpoints included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). RESULTS: Thirty-one patients were enrolled. 39% had high grade serous ovarian cancer, 23% were platinum-sensitive, 55% were platinum-resistant, 23% were platinum-refractory, and 84% had tumors that had a PD-L1 combined positive (CPS) score ≥1. ORR (95% CI) was 26% (12%-45%) by investigator assessment and 35% (19%-55%) by blinded independent central review (BICR). Per BICR, median DOR was 9.2 (1.5+ to 37.8+) months. ORRs (95% CI) by BICR were 35% (9/26 patients; 17%-56%) for PD-L1 CPS ≥ 1 disease and 50% (2/4 patients; 7%-93%) for PD-L1 CPS < 1 disease. Median (95% CI) PFS by BICR and OS were 6.2 (4.0-8.5) months and 21.3 (11.7-32.3) months, respectively. Treatment-related AEs occurred in 94% of patients (grade 3-4, 77%). One patient died from treatment-related hypovolemic shock. CONCLUSIONS: Lenvatinib plus pembrolizumab demonstrated antitumor activity as fourth line therapy in patients with advanced ovarian cancer, and no unanticipated safety signals were identified. Responses were observed regardless of PD-L1 status.

RESUMEN

PURPOSE: To evaluate the efficacy and safety of transarterial chemoembolization (TACE) combined with regorafenib (hereafter, TACE-regorafenib) or camrelizumab (hereafter, TACE-camrelizumab) for treating hepatocellular carcinoma (HCC) with untreatable progression after TACE and sorafenib therapy. METHODS: The medical records of patients with HCC who received TACE-regorafenib or TACE-camrelizumab between September 2018 and December 2023 were retrospectively evaluated. Therapeutic response, overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were compared between the two groups. RESULTS: A total of 76 patients were enrolled in this study, with 41 and 35 patients in the TACE-regorafenib and TACE-camrelizumab groups, respectively. The objective response rates in the TACE-regorafenib and TACE-camrelizumab groups were 9.8% and 8.6%, respectively, with no statistically significant difference between the two groups (P = 0.859). Similarly, there was no statistically significant difference in disease control rates between the two groups (61.0% vs 68.6%, P = 0.838). The median OS was 11 months in the TACE-regorafenib group and 10 months in the TACE-camrelizumab group, with no significant difference between the two groups (P = 0.348). The TACE-regorafenib group had a median PFS of 7 months, which was significantly longer than that of the TACE-camrelizumab group (4 months, P = 0.004). There was no significant difference in the incidence of AEs between the two groups (P = 0.544). CONCLUSIONS: TACE-regorafenib was safe, well-tolerated, and showed promising efficacy in patients with sorafenib-refractory advanced HCC, whereas TACE-camrelizumab demonstrated similar survival benefits.

RESUMEN

BACKGROUND: This meta-analysis was dedicated to evaluating the effectiveness and safety of Atezolizumab plus Bevacizumab (Atez/Bev) and Lenvatinib (LEN) as first-line systematic therapy for unresectable hepatocellular carcinoma (u-HCC). METHODS: The prospective protocol for this study was registered with the PROSPERO (Registration number: CRD42022356874). Literature searches were conducted in PubMed, EMBASE database Cochrane Library, and Web Science to determine all clinical controlled studies that reported Atez/Bev and LEN for treating u-HCC. We. evaluated as primary end-point overall survival (OS) and progression-free survival (PFS), as well as other outcomes such as tumor response and adverse events (AEs).Quality assessment and data extraction of studies were conducted independently by three reviewers. Mean difference (MD) and odds ratio (OR) with 95% confidence interval (CI) were calculated using a fixed-effects or random-effects model. The meta-analysis was performed with RevMan 5.3 software. RESULTS: 12 retrospective cohort studies (RCSs) involving a total of 4948 patients were finally included. The results showed that compared with LEN, Atez/Bev can improve the patient's PFS (HR = 0.80, 95% CI: 0.72 ~ 0.88; p < 0.0001) and reduce the rate of overall AEs (OR = 0.46 95% CI: 0.38 ~ 0.55, p < 0.00001) and grade ≥ 3 AEs (OR = 0.43; 95% CI: 0.36 ~ 0.51, p < 0.00001), while there is no difference between OS and treatment responses rate (objective response rate, disease control rate, complete response, partial response, progressive disease, and stable disease) between two groups. In addition, the subgroup analysis shows that Atez/Bev can promote the OS of patients with viral hepatitis. (HR = 0.79, 95% CI: 0.67 ~ 0.95; p = 0.01), while LEN has an advantage in improving OS in patients with Child-Pugh grade B liver function (HR = 1.98, 95% CI: 1.50 ~ 2.63; p < 0.00001). CONCLUSION: Current evidence shows that compared with LEN, Atez/Bev has more advantages in PFS and safety in treating u-HCC and can improve the OS of patients with viral. LEN has advantages in improving the OS of patients with grade B liver function. However, more multicenter randomized controlled experiments are needed in the future to verify our results.
