    Abstract: e16119 Background: In Study 202, pts received LEN 12 mg/d for treatment of unresectable (u)HCC, irrespective of BW. Correlations between early dose adjustments and BW in Study 202 led to BW-adjusted dosing in the phase 3 REFLECT study of LEN in uHCC. In REFLECT, pts 〈 60 kg received LEN 8 mg/d and pts ≥60 kg received LEN 12 mg/d. While improvements in safety were expected by reducing the LEN starting dose to 8 mg/d in pts 〈 60 kg, any differences in safety and efficacy of BW-adjusted dosing vs standard dosing among pts with lower BW have yet to be determined. Herein, we compare safety and efficacy of LEN based on pts’ BW ( 〈 60 kg vs ≥60 kg) in Study 202 (LEN 12 mg/d irrespective of BW) and in Japanese pts in REFLECT (dose adjusted by BW). Methods: This ad hoc analysis included all pts from Study 202 (n=46; all Asian, 43 Japanese) and Japanese pts from REFLECT (n=81). Safety and efficacy were assessed in Study 202 and REFLECT according to pt BW ( 〈 60 kg vs ≥60 kg). Tumors were assessed using mRECIST, by independent radiologic review. Results: In Study 202, pts in the 〈 60 kg group had a median treatment duration of 5.8 mos and received 57% of the LEN planned starting dose (PSD); pts in the ≥60 kg group had a median treatment duration of 9.4 mos and received 78.6% of the LEN PSD. Among Japanese pts in REFLECT, median treatment duration was 5.7 mos in both treatment groups; pts in the LEN 8 mg group received 79.1% of the PSD and pts in the LEN 12 mg group received 70.7% of the PSD. In Study 202, treatment-related adverse events (TRAEs) led to dose reduction in 80.8% of pts in the 〈 60 kg group and 55% of pts in the ≥60 kg group. In REFLECT, TRAEs led to dose reductions in 52.5% of pts in the LEN 8 mg group and 70.7% of pts in the LEN 12 mg group. Serious TRAEs occurred at incidences of 46.2% and 10.0% in Study 202 in the 〈 60 kg and ≥60 kg groups, and 15.0% and 22.0% in REFLECT in the LEN 8 mg and LEN 12 mg groups, respectively. Efficacy results are in the Table. Conclusions: Despite the small sample size, this comparison of Study 202 pts and Japanese pts from REFLECT indicates that BW-adjusted LEN dosing in pts with uHCC yielded comparable efficacy between pts 〈 60 kg who received LEN 8 mg and pts ≥60 kg who received LEN 12 mg. The safety profile was favorable in pts 〈 60 kg who received LEN 8 mg in REFLECT vs those who received LEN 12 mg in Study 202. Fewer serious TRAEs and dose reductions due to TRAEs were observed in pts with lower BW who received the LEN 8 mg starting dose in REFLECT. These data suggest that by reducing the starting dose from LEN 12 mg to 8 mg in pts with uHCC and lower BW ( 〈 60 kg), safety is improved without compromising efficacy.

    Association between overall survival and adverse events with lenvatinib treatment in patients with hepatocellular carcinoma (REFLECT).
    American Society of Clinical Oncology (ASCO) ; 2019

    Abstract: 317 Background: In the phase 3 REFLECT study, lenvatinib (LEN) demonstrated a treatment effect on overall survival (OS) by statistical confirmation of non-inferiority to sorafenib (SOR) in patients (pts) with unresectable hepatocellular carcinoma (uHCC), who had not received prior treatment for advanced disease (Kudo M et al, Lancet 2018). Lenvatinib is approved in several major markets for the first line systemic treatment of uHCC. The most common adverse events (AEs) in pts treated with LEN were hypertension and diarrhea. In addition, LEN showed a different AE profile from that of SOR. Pts who received LEN experienced more instances of hypertension, proteinuria, dysphonia, and hypothyroidism than patients who received SOR. Recently, hypertension in LEN-treated pts with differentiated thyroid cancer was shown to be correlated with improved efficacy. Here we report the post hoc analysis exploring whether AEs associated with LEN were correlated with longer OS in REFLECT. Methods: 478 Pts were randomized to receive LEN (12 mg/d for actual body weight ≥ 60 kg or 8 mg/d for actual body weight 〈 60 kg). Subgroup analyses were conducted based on whether pts treated with LEN experienced any-grade AEs of interest (AEIs). OS was estimated by the Kaplan-Meier method. Results: The AEIs in pts treated with LEN were hypertension (42%), diarrhea (38%), proteinuria (24%), dysphonia (24%), and hypothyroidism (16%). OS was longer in pts who had several AEs of interest than in those who did not (table). Conclusions: In pts treated with LEN, the occurrence of hypertension, diarrhea, proteinuria, or hypothyroidism was generally associated with longer OS in pts with uHCC in this post hoc exploratory analysis. The potential confounding factors at baseline should be further investigated. Clinical trial information: NCT01761266. [Table: see text]

    Analysis of survival and objective response (OR) in patients with hepatocellular carcinoma in a phase III study of lenvatinib (REFLECT).
    American Society of Clinical Oncology (ASCO) ; 2019

    Abstract: 186 Background: In REFLECT, Lenvatinib (LEN) demonstrated treatment effect on overall survival (OS) by statistical confirmation of noninferiority to sorafenib (SOR). OR rates for LEN versus SOR were: 24% versus 9% by investigator review and 41% versus 12% by independent review (Kudo et al 2018). Since the relationship between OR and OS in phase III HCC studies is unclear, we explored the relationship between OR and OS in REFLECT. Methods: OR assessed by investigators per mRECIST were used to analyze the association between OR and OS of pts treated with LEN or SOR. The median OS of responders (CR or PR) was compared to that of nonresponders (SD, PD, or UNK/NE) irrespective of treatment. Landmark analyses were performed by OR status at several fixed time points as sensitivity analyses, and the effect on OS was evaluated by Cox regression with OR as a time-dependent covariate, with other prognostic factors. Results: Median OS was 22.4 months for responders and 11.4 months for nonresponders. Hazard ratios (HR) of landmark analyses at 2, 4, and 6 months were 0.75 (95% CI, 0.57–0.98), 0.72 (95% CI, 0.56–0.92), and 0.73 (95% CI, 0.57–0.93). Independent predictors of OS based on unstratified Cox regression are in the table. Conclusions: In REFLECT, OR was an independent predictor of OS in pts with HCC regardless of treatment. The results indicate this correlation is worth further investigation. Clinical trial information: NCT01761266. [Table: see text]

    Abstract: 4001 Background: SOR is the only approved agent in uHCC and new options are needed. LEN, an inhibitor of vascular endothelial growth factor receptors 1‒3, fibroblast growth factor receptors 1‒4, platelet derived growth factor receptor α, RET, and KIT, showed activity in uHCC in a phase II trial. We report a phase III trial of LEN vs SOR as first-line therapy for uHCC. Methods: In this randomized, open-label, noninferiority (NI) study, pts had uHCC, ≥ 1 measurable target lesion, Barcelona Clinic Liver Cancer stage B or C, Child-Pugh class A, ECOG PS ≤ 1, and no prior systemic therapy. Pts were randomized 1:1 to LEN (body weight ≥ 60 kg: 12 mg/day; 〈 60 kg: 8 mg/day) or SOR 400 mg twice daily. The primary endpoint was overall survival (OS). The OS hazard ratio (HR) and its 95% CI were estimated with a stratified Cox proportional hazard model. The predefined NI margin was 1.08. Secondary efficacy endpoints were progression-free survival (PFS), time to progression (TTP) and objective response rate (ORR) by modified RECIST. Type I error rates for secondary efficacy endpoints were controlled with a fixed sequence procedure at 2-sided α = 0.05 after OS NI was claimed. Results: 954 Pts enrolled (LEN: 478; SOR: 476). Efficacy outcomes are shown in the table. A similar number of pts in both arms had treatment-emergent adverse events (TEAEs). Most common LEN TEAEs were hypertension (42%), diarrhea (39%), decreased appetite (34%), decreased weight (31%), and fatigue (30%). Median (range) treatment duration was 5.7 mos (0−35.0) for LEN and 3.7 mos (0.1−38.7) for SOR. 13% Of LEN-treated and 9% of SOR-treated pts discontinued due to adverse events. 33% Of LEN-treated and 39% of SOR-treated pts received second-line therapy. Conclusions: LEN is noninferior in OS, and achieves statistically significant and clinically meaningful improvements in PFS, TTP, and ORR, as first line therapy for uHCC. TEAEs were consistent with the known LEN safety profile. Clinical trial information: NCT01761266. [Table: see text]

    Abstract: 320 Background: Lenvatinib is an oral tyrosine kinase inhibitor targeting VEGFR1-3, FGFR1-4, RET, KIT and PDGFRβ. Maximum tolerated dose (MTD) of lenvatinib for solid tumor pts was determined to be 25 mg once daily dosing (qd), and MTD for HCC pts with Child-Pugh A was determined to be 12 mg qd. A preliminary assessment of response rate is presented in this report. Methods: Between July 9, 2010 and June 22, 2011, 46 pts with advanced HCC with Child-Pugh A were enrolled in Japan (n=43) and Korea (n=3). Pts may have received up to one prior treatment regimen including sorafenib. Pts were treated with a starting dose of lenvatinib 12 mg once daily in 28 day cycles until disease progression or development of unmanageable toxicities. Response rate was assessed by RECIST 1.1 (modified to evaluate viable lesions). Results: The first 42 consecutively enrolled pts (med age: 67; M: 76%, F: 24%) were evaluable for response and form the basis of this report. 45% had extra hepatic spread, 24% received prior chemotherapy and 91% had prior locoregional therapy. 19% were withdrawn from therapy due to adverse event. The most common toxicities were hypertension 71% (Gr 3: 48%), anorexia 50% (Gr 3: 2.4%), proteinuria 45% (Gr 3: 14%), palmar-plantar erythrodysaesthesia syndrome 43% (Gr 3: 4.8%), fatigue 43% (Gr 3: 0%), and thrombocytopenia 33% (Gr 3: 19%). No pts experienced Gr 4 toxicity. Confirmed Partial Responses (PRs) were observed in 14 pts (RR: 33%, 95% CI: 20-50) based on investigator assessment. Updated efficacy including median Time to Progression and survival data will be reported. Conclusions: Lenvatinib 12 mg qd when administered to advanced HCC pts with Child-Pugh A is associated with manageable toxicity. The preliminary assessment of efficacy on the basis of overall response rate suggests that lenvatinib may represent a new potential therapeutic agent for advanced HCC pts. Further assessment of safety and efficacy is ongoing.

    Abstract: 309 Background: Lenvatinib is an oral tyrosine kinase inhibitor of VEGFR1-3, FGFR1-4, PDGFRα, RET, and KIT. A phase 1/2 trial in pts (n = 46) with advanced HCC and Child-Pugh score A treated with lenvatinib 12 mg once daily showed a median overall survival (OS) of 18.7 months, and a median time to progression (TTP) of 12.8 months by investigator review and 7.4 months by independent radiologic review (IRR). Objective response rate was 37.0% as assessed by modified Response Evaluation Criteria in Solid Tumors (mRECIST). Based on these results, a phase 3 study comparing the efficacy and safety of lenvatinib versus sorafenib is ongoing. Here, we report subgroup analyses of the phase 2 part of this study. Methods: Subgroups were retrospectively analyzed by Barcelona clinic liver cancer (BCLC) staging, disease etiology, prior therapy for advanced HCC (including sorafenib), and baseline Alpha-fetoprotein (AFP) levels. Efficacy endpoints including OS and TTP by IRR were assessed for each subgroup. TTP based on mRECIST and OS were assessed from the date of study registration to progressive disease and to death, respectively. Results: Median TTP and OS for each of the relevant subgroups of baseline characteristics are shown in the table. Conclusions: Pts with advanced HCC treated with lenvatinib showed similar TTP regardless of subgroup. Although the number of patients was limited, lenvatinib treatment shows promising efficacy even in patients with hepatitis B virus. Clinical trial information: NCT00946153. [Table: see text]

    Abstract: 316 Background: Lenvatinib (LEN) demonstrated statistical confirmation of noninferiority versus sorafenib (SOR) for overall survival (OS), and improved progression-free survival (PFS), time to progression, and objective response rate (ORR) in pts with uHCC in REFLECT (Kudo M et al, Lancet 2018). We report the efficacy and safety of LEN by starting dose, which was based on body weight (BW). Methods: In REFLECT, a multicenter, open-label, noninferiority trial, pts with uHCC were randomized 1:1 to LEN (BW 〈 60 kg: 8 mg/d; BW ≥ 60 kg: 12 mg/d; QD) or SOR (400 mg BID). Efficacy was analyzed by intention-to-treat; safety was analyzed in pts who received treatment, in each dose group. Results: Of 478 pts randomized to LEN, 151 (male, 70%; median age, 65 y) and 327 (male, 91%; median age, 62 y) were included in the LEN starting dose groups of 8 mg/d or 12 mg/d, respectively. In the 8-mg group, 14% of pts were from Western regions; 86% from Asia-Pacific. In the 12-mg group, 42% were from Western regions; 58% from Asia-Pacific. Median OS was 13.4 (95% CI: 10.5–15.7) and 13.7 months (95% CI: 12.0–15.6); ORR was 22.2% and 24.9% for pts with BW 〈 60 kg and ≥ 60 kg, respectively. Median PFS was 7.4 months in both groups. Median duration of treatment: 8-mg group, 5.6 months; 12-mg group, 6.3 months. Mean LEN relative dose intensity: 8-mg group, 87.7%; 12-mg group, 87.5%. Most common any-grade adverse events (AEs; 8-mg vs 12-mg) were hypertension (43% vs 42%), diarrhea (35% vs 40%), decreased appetite (33% vs 35%), weight loss (29% vs 32%), and fatigue (28% vs 31%). Adjusted by treatment duration, AE rates (episodes/patient-year) were similar for 8-mg versus 12-mg: hypertension (0.79 vs 0.78), diarrhea (1.06 vs 0.99), decreased appetite (0.63 vs 0.59), weight loss (0.50 vs 0.51), and fatigue (0.52 vs 0.47). Pharmacokinetic profiles were similar between groups. Conclusions: LEN efficacy was comparable between groups. Exposure to LEN was greater for the 12-mg versus 8-mg group. When AEs were adjusted by treatment duration, no notable differences in the AE profiles between the starting doses were observed. Altogether, these results support the 8-mg and 12-mg starting doses based on BW of 〈 60 kg and ≥ 60 kg, respectively, in REFLECT. Clinical trial information: NCT01761266.

    Abstract: 345 Background: LEN showed treatment effect on OS by statistical demonstration of noninferiority to SOR in a phase 3 study in pts with uHCC, with significant improvement ( P 〈 0.00001) in median PFS (7.4 vs 3.7 mos; HR: 0.66; 95% CI, 0.57−0.77), median TTP (8.9 vs 3.7 mos; HR: 0.63. 95% CI, 0.53−0.73), and ORR (24% vs 9%). Tumor assessments were by investigator review (IR) per modified RECIST (mRECIST). We present IIR results to assess concordance for IR vs IIR and mRECIST vs RECIST 1.1 by IIR. Methods: In this open-label study, pts with uHCC, ≥ 1 measurable target lesion, BCLC stage B or C, Child-Pugh class A, ECOG PS ≤ 1, and no prior systemic therapy were randomized 1:1 to LEN (body weight ≥60 kg: 12 mg/d; 〈 60 kg: 8 mg/d) or SOR 400 mg twice daily. Primary endpoint was OS. Secondary efficacy endpoints were PFS, TTP, and ORR by mRECIST. IR tumor assessments were done every 8 wks. Post hoc exploratory blinded IIR studies were done using mRECIST and RECIST 1.1 (first timepoint at wk 8). Results: A total of 954 pts enrolled (LEN: 478; SOR: 476), of which 952 (99.8%) pts were IIR assessable (table). Adjudication rate (AR; percentage of cases adjudicated due to disagreement) for timepoint of PD was similar for mRECIST (47%) and RECIST 1.1 (45%); for responder (CR or PR)/nonresponder (SD, PD, or not evaluable [NE]), it was 32% for mRECIST and 17% for RECIST 1.1. PFS and TTP results were nearly the same per mRECIST by IIR as by IR and the same by IIR per mRECIST and RECIST 1.1. Very good concordance was seen between IIR and IR in best overall response (BOR) per mRECIST with the greatest discordance due to more pts being assessed as PR than SD for LEN. Conclusions: IIR supports IR results. ORR was higher in both arms by IIR vs IR but relative ORR was preserved in LEN vs SOR. Higher AR for IIR per mRECIST on response may be due to the greater number of responders or disease complexity. Median PFS and TTP were the same by IIR per mRECIST and RECIST 1.1, showing these data can be compared between methods. Clinical trial information: NCT01761266. [Table: see text]

    Abstract: 263 Background: Gemcitabine (Gem) monotherapy or Gem-based combination therapy is a standard first-line therapy for advanced pancreatic cancer (PC). There is no consensus on second-line therapy in patients (pts) with disease progression (PD) after Gem-based therapy. S-1, an oral fluoropyrimidine derivative, is commonly used for the second-line treatment of PC in Japan. Shitara et al previously reported that IRIS regimen showed that 44% of response rate (RR), 4.9 mo of median progression free survival (PFS), and 11.3 mo of median overall survival (OS), respectively. Therefore a randomized phase II trial was conducted to evaluate the efficacy and safety of IRIS compared with S-1 alone in the second-line setting. Methods: The inclusion criteria were as follows: (1) histologically or cytologically proven pancreatic adenocarcinoma or adenosquamous carcinoma; (2) confirmed PD after Gem treatment; (3) ECOG PS, 0-1; (4) measurable metastatic lesion based on RECIST criteria; (5) age ≥ 20 years; (6) total bilirubin 〈 2.0 mg/dL. Patients were randomized to receive either IRIS (CPT-11 100 mg/m 2 , iv, d1,15 plus S-1 80/100/120 mg/day based on BSA, po, d1-14, q4w; Arm A) or S-1 (80/100/120 mg/day based on BSA, po, d1-28, q6w; Arm B). The primary endpoint was to compare PFS in Arm A and Arm B. Results: Of a total of 137 pts enrolled between Nov 2008 and Mar 2011, 127 were eligible (60 randomized to Arm A and 67 to B). Median PFS in Arm A and B was 107 and 58 days, respectively (HR= 0.767; 95% CI, 0.527-1.114; p=0.1750). Median OS in Arm A and B was 208 and 176 days, respectively (HR=0.749; 95% CI, 0.512-1.093; p=0.1338). RR was 18.3% in Arm A (11/60; 95% CI, 9.5-30.4) and 6.0% in Arm B (4/67; 95% CI, 1.7-14.6)(p=0.0311). The incidences of grade 3/4 toxicities were as follows: neutropenia (15.6% and 4.3%), anorexia (23.4% and 17.3%), nausea (6.3% and 2.9%), and diarrhea (3.1% and 2.9%) in Arm A and B, respectively. Both regimens were tolerable. Conclusions: Although IRIS showed no significant improvement in PFS or OS compared with S-1 alone in this study, it showed significant advantage in RR, and favorable HR in both of PFS and OS. IRIS might have potential power to treat second-line PC patients. Further study is warranted. Clinical trial information: JapicCTI-080657.
