Background: Although lenvatinib has become the standard therapy for hepatocellular carcinoma (HCC), the high incidence rate of adverse events (AEs) is an issue. This study aimed to clarify the AEs of lenvatinib and the therapeutic impact of five days-on/two days-off administration (i.e., weekends-off strategy) for lenvatinib. Methods: We retrospectively assessed the therapeutic effects and AEs of 135 patients treated with lenvatinib, and the improvement of tolerability and therapeutic efficacy of 30 patients treated with the weekends-off strategy. We also evaluated lenvatinib-induced vascular changes in tumors and healthy organs using a mouse hepatoma model. Results: The incidence rates of any grade and grade ≥ 3 AEs were 82.1% and 49.6%. Fatigue was the most important AE since it resulted in dose reduction and discontinuation. Of the 30 patients who received weekends-off lenvatinib, 66.7% tolerated the AEs. Although 80.8% of the patients showed progression after dose reduction, the therapeutic response improved in 61.5% of the patients by weekends-off lenvatinib. Notably, weekends-off administration significantly prolonged the administration period and survival (p < 0.001 and p < 0.05). The mouse hepatoma model showed that weekends-off administration contributed to recovery of vascularity in the organs. Conclusion: Weekends-off administration of lenvatinib was useful to recover the therapeutic response and tolerability toward AEs.

Abstract Background: The current standard of treatment for advanced hepatocellular cancer Hepatocellular carcinoma (HCC) is Sorafenib. Data regarding its tolerance and adverse event profile in Indian patients is scarce. Materials and Methods: The primary aim of this analysis was to assess the adverse events (Grade 3 and Grade 4 as per CTCAE v4.0) and requirements for dose reduction with sorafenib in advanced HCC. Details of consecutive patients started on 800 mg/day dosing were obtained from a prospectively maintained database (over a period of 6 months) and analyzed. Results: Thirty-nine patients were available for inclusion in the study. Median age was 58 years (range: 20–75). All patients were classified as Barcelona clinic liver cancer C. Common side effects seen were liver dysfunction (38.5%), hand-foot-syndrome-rash (HFSR) (Grade 2 and 3-25.6%), fatigue (Grade 2 and Grade 3–10.3%), and diarrhea (7.7%). Dose reduction was required in 43.6% of patients. Drug interruptions/cessation was required in 38.5% of patients within the first four months of treatment. Nearly 41% of patients required cessation of sorafenib due to intolerable side-effects while 28.2% stopped sorafenib due to progressive disease. At a median follow-up of 4.9 months, median event-free survival (EFS) was 4.20 months (95% confidence interval: 3.343–5.068). Conclusion: A higher incidence of liver dysfunction and HFSR is seen in Indian patients as compared to published data. A significant proportion of patients required cessation of sorafenib due to adverse events in our series. However, EFS remains on par with that seen in larger studies with sorafenib in advanced HCC.

IntroductionThe treatment of relapsed/refractory multiple myeloma (RRMM), a common hematological malignancy, remains a great challenge in China, partially due to the limited accessibility to novel agents and inadequate public health insurance coverage. Ixazomib, a novel oral proteasome inhibitor (PI), was approved by the China Food and Drug Administration (CFDA) for RRMM in 2018. While bortezomib, a traditional PI, is the recommended agent in the clinical guideline for MM. Here, we compared their costs and effectiveness.MethodsRRMM patients who has received an ixazomib-based regimen (at least 2 cycles) were analyzed. Using a propensity score matching method, we generated a control group of RRMM patients who received the bortezomib-based regimen. The criteria included the number of treatment lines, age, and the revised international staging system stage (R-ISS) which representing the disease stage for myeloma, and paired at a ratio of 1:2 (allowing one control to match multiples). The difference in hospitalization stay, grade 3/4 adverse events rates, overall response rate (ORR), mortality during treatment, and treatment costs was then compared.ResultsNineteen patients received ixazomib and twenty-seven that received bortezomib were included. The ixazomib-group demonstrated a shorter hospital stay (9 days versus 27 days, p < 0.001), lower grade 3–4 adverse events rates (42.1% versus 55.6%, p < 0.001), higher ORR (63.2% versus 48.1%, p = 0.228), and lower mortality rate during treatment (0% versus 7.4%, p = 0.169) than that of bortezomib-group. The ixazomib group had lower total costs (127,620CNY versus 156,424CNY [18,033USD versus 22,103USD], p > 0.05), lower drug costs (98,376CNY versus 103,307CNY [13,901USD versus 14,598USD], p > 0.05), and the lower costs of supportive treatment (5,507CNY versus 14,701 CNY [778USD versus 2,077USD], p < 0.001). Only in terms of self-funded costs, the bortezomib-based regimen was significantly lower (37,127CNY versus 11,521CNY [5,246USD versus 1,628USD], p < 0.001).ConclusionsCompared with the bortezomib-based regimen, the ixazomib-based regimen has better therapeutic effects on MM patients while saving costs. Hence, it may be preferable for use in the treatment of RRMM in China.

Aim: To evaluate sorafenib treatment in Latin American patients with unresectable hepatocellular carcinoma in the real-world GIDEON study. Patients & methods: Sorafenib administration, safety and efficacy were analyzed by Child–Pugh status. Results: Of 90 evaluable patients (37% Child–Pugh A, 46% Child–Pugh B and 3% Child–Pugh C at study entry), 97% started sorafenib at 800 mg/day. Patients with Child–Pugh B7 had the longest median treatment duration of sorafenib (33.1 weeks). Sorafenib-related adverse events occurred in 58% of patients with Child–Pugh A (21% grade 3/4) and 46% with Child–Pugh B (7% grade 3/4). Conclusion: Sorafenib had a similar safety profile across patients with Child–Pugh A and B and is a treatment option for both groups.

Objective: To evaluate the use of transarterial chemoembolisation (TACE) combined with microwave ablation (MWA) to treat patients with hepatocellular carcinoma (HCC) and type Ⅱ–Ⅲ portal vein tumour thrombosis (PVTT) intolerant to targeted drug (TG) therapy. Methods: A total of 18 patients with HCC and type Ⅱ–Ⅲ PVTT intolerant to TG were enrolled between June 2015 and December 2019, who were treated with TACE + MWA (MWA group). 24 patients were treated with TACE + TG (TG group; control cohort). Time to progression and overall survival (OS) were analysed along with the incidence of adverse events. Results: The median follow-up time was 19.0 months (9.0–32.0 months). The median OS was 17.0 months (8.3–29.3 months; MWA group) and 13.5 months (5.5–22.5 months; TG group) and was not significantly different. The 1- and 2 year OS was also comparable (MWA group: 66.7%, 44.4% vs Target group: 41.7%, 29.2%). Time to progression showed no distinct differences (MWA group: 11.5 months; TG group: 9.0 months) between the two groups. Moreover, the incidence of major Grade 3–4 adverse events in the MWA group (5.6%) was similar to those in the TG group (8.3%). Conclusion: TACE + MWA and TACE + TG were comparable in their safety and efficacy in patients with HCC, type Ⅱ–Ⅲ PVTT, and intolerance to TG. Advances in knowledge: TACE + MWA can be used as a palliative treatment alternative for TACE + TG in patients with HCC, type Ⅱ–Ⅲ PVTT, and intolerance to TG.

Abstract Abstract 919 Background: Pralatrexate enters cancer cells via the reduced folate carrier-1 (RFC-1) and is efficiently polyglutamated by folylpolyglutamyl synthetase (FPGS), leading to high intracellular retention. In a Phase 1/2 study of patients with hematologic malignancies, pralatrexate demonstrated activity in aggressive T-cell lymphoma with a maximum tolerated dose (MTD) of 30 mg/m2 once weekly for 6 of 7 weeks. The generally indolent course of CTCL may be better treated at lower doses in a maintenance fashion if a lower incidence and severity of adverse events can be achieved while preserving activity. PDX-010 is an open-label, single-agent, multicenter, Phase 1 dose-reduction trial in patients with relapsed or refractory CTCL. The primary objective is to identify an optimal dose and schedule of pralatrexate for these patients. Methods: Eligibility included mycosis fungoides (MF), Sézary syndrome (SS), and primary cutaneous anaplastic large cell lymphoma (ALCL); with disease progression after at least 1 prior systemic therapy. The pralatrexate dose and schedule started at 30 mg/m2 by IV push on 3 of 4 weeks and subsequent cohorts received reduced doses (20, 15, 10 mg/m2) and/or schedules (3/4 or 2/3 weeks) of pralatrexate based on tolerability. All patients received supplementation with vitamin B12 1 mg intramuscularly every 8-10 weeks and folic acid 1 mg orally once daily. As we sought a well tolerated regimen the definition of DLTs to trigger dose reduction included toxicities such as grade ≥ 3 neutropenia, grade ≥ 2 thrombocytopenia, febrile neutropenia, grade ≥ 2 mucositis/stomatitis, and any toxicity leading to dose omission or reduction in cycle 1. If DLT occurred and a response was seen, the following cohort was opened at the next lower dose or next less frequent schedule. Response was evaluated by modified severity-weighted adjustment tool (SWAT) every 2 cycles for 6 months and then every 4 cycles. For patients with lymph node involvement, scans were completed at baseline and upon clinical response or end of treatment, whichever occurred first. Results: Thirty-one patients received pralatrexate, with 18 (58%) men and median age of 57 yrs (range, 30-81). Patients had received a median of 6 prior therapies (range, 1-25). Cohorts at the following doses/schedules were enrolled: 30 mg/m2 x 3/4 weeks (n=2), 20 mg/m2 x 3/4 weeks (n=3), 20 mg/m2 x 2/3 weeks (n=7), 15 mg/m2 x 3/4 weeks (n=6), 15 mg/m2 x 2/3 weeks (n=3), and 10 mg/m2 x 3/4 weeks (n=10). Patients received pralatrexate for a median of 72 days (range, 7-491+); 4 patients received >10 cycles of treatment. The most common treatment-related adverse events (all grades) were mucositis (18 patients [58%]), nausea (14 patients [45%]), fatigue (14 patients [45%]), pyrexia (7 patients [23%]), vomiting (6 patients [19%]), anemia (6 patients [19%]), and edema (5 patients [16%]). Grade 3-4 treatment-related toxicities in >1 patient each were mucositis (4 patients [13%]) and anemia (2 patients [6%]). Mucositis was dose limiting (≥ grade 2) in 8 patients (26%). A total of 11 responses were observed, including 2 complete responses and 9 partial responses. In the 18 patients who received pralatrexate at a dose intensity of 15 mg/m2 x 3/4 weeks or greater, the objective response rate was 56% (10/18 patients). This appeared to be the threshold dose for substantial activity in CTCL, below which the incidence of responses decreased in this dose de-escalation trial. Conclusion: Pralatrexate shows impressive activity in the treatment of relapsed CTCL. The optimal dose and schedule that provided activity with tolerability for CTCL was determined to be pralatrexate 15 mg/m2 weekly on 3 of 4 weeks. This cohort is being expanded to better assess efficacy and durability. Disclosures: Horwitz: Allos Therapeutics, Inc: Consultancy, Research Funding. Duvic:Allos Therapeutics, Inc.: Research Funding.

Abstract Abstract 2929 Background: Two pivotal phase 3 trials (MM-009 and MM-010) randomized 704 pts to assess Len+Dex vs placebo plus dexamethasone (Dex) in RRMM. The results demonstrated the significant overall survival (OS) benefit of Len+Dex vs Dex (38.0 vs 31.6 mos; p =.045) despite crossover of 48% of Dex pts to the Len+Dex arm at unblinding or progression (Dimopoulos MA et al. Leukemia 2009;23 :2147-52). This is an analysis of the long-term outcomes and safety of continuous Len+Dex treatment. Methods: This retrospective analysis pooled pts treated with Len+Dex in MM-009 and MM-010, with a median follow-up of 48 mos for surviving pts. A subset of pts with progression-free survival (PFS) of ≥ 2 yrs was selected. Prognostic factors for PFS within this subgroup of pts were identified by incorporating all baseline covariates with a univariate p <.15 into multivariate Cox regression analyses, and all possible models were fitted using SAS 9.2. Adverse event (AE) management and dosing for pts with PFS ≥ 2 yrs was compared with that for all pts treated with Len+Dex in order to evaluate if differences in pt management could contribute to better clinical outcomes. Incidence rates for AEs were calculated using person-yrs of follow-up. Data from pts who received Len+Dex in MM-009 (up to July 23, 2008) and MM-010 (up to March 2, 2008) were included in this analysis. Results: Among all pts treated with Len+Dex (N = 353), a total of 64 pts (18%) achieved PFS ≥ 2 yrs. For these 64 pts, median age was 61 yrs (range 33–81 yrs), 48% received > 1 prior therapy, and 57% had β2-microglobulin levels of ≥ 2.5mg/L. All these pts achieved a ≥ partial response (PR), including 67% with a ≥ very good PR and 50% with a complete response. Median time to first response was 2.8 mos (range 1.9–18.2 mos) which is comparable to that of all pts treated with Len+Dex. Median duration of response was not reached vs 15.5 mos, respectively. With median follow-up of 49 mos, the 3-yr OS is 94% (95% confidence interval [CI] 88.06–99.94). In a multivariate Cox regression analysis, shorter PFS was predicted with higher baseline β2-microglobulin level (hazard ratio [HR] 1.07; 95% CI 1.02–1.12) and lower hemoglobin (HR 0.91; 95% CI 0.84–0.99), as well as a higher number of prior therapies (HR 1.18; 95% CI 1.02–1.37). The median duration of treatment was longer among pts with PFS ≥ 2 yrs vs all pts treated with Len+Dex (46.2 mos [range 11.3–58.3] vs 9.8 mos [range 3.8–24], respectively). A higher proportion of these pts had a dose reduction within 12 mos after start of therapy vs all pts treated with Len+Dex (57% vs 24%, respectively). Dex dose was reduced in 27% of pts with PFS ≥ 2 yrs. Among pts without Len dose reduction, 31% had Dex dose reduction within the first 4 cycles. Granulocyte colony-stimulating factor was administered for the management of neutropenia in 39% of pts with PFS ≥ 2 yrs vs 25% of all pts treated with Len+Dex. Low discontinuation rates due to AEs were observed in both groups (12.5% vs 18.7%, respectively). The incidence rates per 100 person-yrs for grade 3–4 AEs among pts with PFS ≥ 2 yrs vs all pts treated with Len+Dex (N = 353) were, respectively: neutropenia (14.9 vs 29), febrile neutropenia (0.9 vs 2.3), thrombocytopenia (2.6 vs 10.2), anemia (4.4 vs 9.5), infection (11.8 vs 20.9), deep vein thrombosis/pulmonary embolism (2.2 vs 8.9), fatigue (2.2 vs 5.5), neuropathy (1.8 vs 3.4), and gastrointestinal disorders (5.3 vs 9.7). The incidence rates per 100 person-yrs for second primary malignancies (SPMs) were similar to that of all pts treated with Len+Dex, respectively: myelodysplastic syndromes (0 vs 0.4), solid tumor (1.8 vs 1.3), and non-melanoma skin cancer (2.3 vs 2.4). These rates are comparable to those expected in people aged > 50 yrs generally (1.4 per 100 person-yrs) (Altekruse SF et al. SEER Cancer Statistics Review, 1975–2007). Conclusions: Long-term continuous therapy with Len+Dex has demonstrated efficacy and is generally well tolerated in pts with RRMM. Overall, 18% of patients treated with Len+Dex achieve a PFS of > 2 yrs. No increase in SPMs was observed with long term Len+Dex therapy. With appropriate AE management, the incidence rates of grade 3–4 AEs remain low. This analysis demonstrates the value of AE management and the need for appropriate dose-adjustment to maintain tolerability, allowing pts to remain on therapy for maximal benefit.

398 Background: mTOR inhibitors are approved in several malignancies including renal cell carcinoma (RCC). The risk of metabolic complications with these agents is not well characterized. Methods: PubMed was searched for articles published from 2001 until 2011. Eligible studies included prospective randomized trials evaluating temsirolimus, everolimus, and ridaforolimus in patients with all solid tumor malignancies. 16 eligible phase II clinical trials and 8 randomized controlled clinical trials were included in a systematic review and meta-analysis and the number of metabolic related AEs including hyperglycemia, hypercholesterolemia, and hypertriglyceridemia were extracted. Incidence rates and incident rate ratios were calculated. Results: In total, 24 trials (including 4,261 patients) were included. The average incidence rate of any grade metabolic adverse events and grade 3-4 metabolic adverse events was 0.70 per patient and 0.11 (95% CI, 0.08, 0.15) per patient respectively. Analysis of the 3,317 patients across 8 RCT’s revealed that the log incidence rate ratio (IRR) of any grade metabolic adverse events with mTOR inhibitor therapy compared with control was 1.08 (95% CI, 0.84, 1.31) using a random-effects model. The risk of grade 3-4 adverse events was also increased with an IRR of 1.52 (95% CI, 1.05, 1.99). The IRR of all grade hyperglycemia was 1.08 (95% CI, 0.76, 1.40) and of grade 3-4 hyperglycemia was 1.66 (95% CI, 1.12, 2.20). The IRR of all grade hypertriglyceridemia was 0.91 (95% CI, 0.56, 1.26) and of grade 3-4 hypertriglyceridemia was 0.70 (95% CI,- 0.43, 1.83). The IRR of all grade hypercholesterolemia was 1.21 (95% CI, 0.77, 1.65) and of grade 3-4 hypercholesterolemia was 1.21 (95% CI, 0.77, 1.65). These findings suggest a statistically significant increase in the risk of hyperglycemia, hypercholesterolemia (all grades and grade 3 and 4), and all grade hypertriglyceridemia associated with mTOR therapy when compared with control. Conclusions: The risk of all grade and grade 3-4 metabolic adverse events are increased in patients treated with mTOR inhibitors compared with control. However, grade 3-4 metabolic adverse events remain relatively uncommon.

AbstractObjectivesMonitoring the early treatment effect of sorafenib in advanced hepatocellular carcinoma (HCC) patients is a diagnostic challenge. In a previous study, we reported the potential role of liver computed tomography perfusion (CTP) in the assessment of the response to sorafenib therapy in HCC. The present study aims to investigate whether sorafenib-targeted genes is correlated with CTP parameter, and investigate the potential of sorafenib-targeted genes in early prediction of therapeutic response to sorafenib in advanced HCC.MethodsA total of 21 HCC patients were enrolled. Sorafenib was administered orally at a dose of 400 mg twice daily continuously. Treatment response was assessed using modified response evaluation criteria in solid tumors (mRECIST) criteria. CTP scanning was performed before and after two weeks of sorafenib treatment using a 320-detector row CT scanner. The perfusion parameters of portal vein flow (PVF), hepatic artery flow (HAF), and perfusion index (PI) were acquired by CTP. The expression levels of several sorafenib-targeted genes were assayed using real-time quantitative PCR and western blot analysis. Logistic regression was performed to analyze the relationship between HAF values and RAF1 expression levels.ResultsAccording to mRECIST, the disease control rate (CR+PR+SD) of treatment group was 70.5% after two months of treatment. Compared to background controls, tumor tissues exhibited higher HAF. A sorafenib-targeted gene, RAF1 expression, was increased in tumor tissues especially in the sorafenib-resistant group. The sorafenib-resistant group exhibited a significantly higher RAF1 expression and HAF than the sensitive group. Moreover, the RAF1 expression is positively correlated with the HAF value.ConclusionRAF1 expression might predict therapeutic effects of sorafenib in advanced HCC, where RAF1 could potentially serve as a molecular marker for monitoring early therapeutic effects after sorafenib treatment.

Arterial Chemoembolization

Objective: To evaluate the feasibility, efficacy and safety of transcatheter arterial chemoembolization (TACE) with HepaSphere for patients with pulmonary or mediastinal metastases from hepatocellular carcinoma (HCC). Methods: Between June 2009 and January 2018, 14 patients with pulmonary or mediastinal metastases from HCC were treated with TACE with a combination of 1–3 chemotherapeutic drugs followed by HepaSphere embolization. As first end point, local tumor response and adverse events were evaluated after the first session of TACE, with Response Evaluation Criteria In Solid Tumors v. 1.1 and Common Terminology Criteria for Adverse Events v. 4 criteria, respectively. Overall survival was evaluated as secondary end point. TACE was repeated on-demand. Results: TACE with HepaSphere was well tolerated with acceptable safety profile and no 30 day mortality. 1 month objective response and disease control rate were calculated to be 7.1 and 100%, respectively. Mean tumor size reduction rate was 15.6±9.5% at the first month. Two Grade 3 cytopenia events were seen (14.3 %), however none of the Grade 2 or more post-embolization syndrome was observed. The median overall survival time was 15.0 months and the 1 year, 3 year and 5 year survival rate were, 57.1%, 28.6%, 19.1%, respectively. Conclusion: Early experience showed that the transarterial treatment with HepaSphere is safe and effective treatment for patients with pulmonary or mediastinal metastases from HCC. Advances in knowledge: Currently, the effects of molecular targeted drugs on HCC metastases are limited and side-effects are relatively frequent. In the present study, transarterial treatment might be a promising treatment for HCC metastasis.
