TPS598 Background: Tyrosine kinase inhibitors can prolong survival in advanced HCC patients, but response rates have been minimal. Recently, immune checkpoint inhibition with nivolumab (nivo) demonstrated objective response rates (ORR) of 15% (escalation phase) and 20% (expansion phase) in the Checkmate 040 study. Pre-clinical and translational studies have demonstrated that IL-8 and tumor associated macrophages (TAMs) contribute to HCC progression and recurrence following treatment. Therefore, rationale exists to evaluate combinatorial approaches to target TAM function combined with checkpoint inhibitory therapy. This phase II, randomized study will evaluate the safety and efficacy of combined anti-CSF1R (Cabiralizumab) or anti-IL-8 (BMS-986253) in combination with Nivo in advanced HCC. Methods: Advanced HCC patients without prior systemic treatment and disease measurable by RECISTv1.1 with Childs A liver function are eligible. Patients will be enrolled (n=25 per arm) to Nivo 240 mg IV Q2 weeks monotherapy, Nivo 240 mg IV + BMS-986253 1200 mg IV Q2 weeks, or Nivo 240 mg IV + Cabiralizumab 4 mg/kg IV Q2 weeks. Primary endpoints include safety and ORR determined by RECISTv1.1. Secondary endpoints include time to response, duration of response, progression free survival, and overall survival. Exploratory endpoints include analysis of tumor microenvironment immune and tumor cell profiling of pre- and on-treatment tumor tissue. Clinical trial information: NCT04050462.

Sunitinib Treatment

PurposeTo assess the safety and efficacy of sunitinib in patients with advanced hepatocellular carcinoma (HCC) and explore biomarkers for sunitinib response.Patients and MethodsWe conducted a multidisciplinary phase II study of sunitinib, an antivascular endothelial growth factor receptor tyrosine kinase inhibitor, in advanced HCC. Patients received sunitinib 37.5 mg/d for 4 weeks followed by 2 weeks of rest per cycle. The primary end point was progression-free survival (PFS). We used functional magnetic resonance imaging to evaluate vascular changes in HCC after sunitinib treatment. Circulating molecular and cellular biomarkers were evaluated before and at six time points after sunitinib treatment.ResultsThirty-four patients were enrolled. The objective response rate was 2.9%, and 50% of patients had stable disease. Median PFS was 3.9 months (95% CI, 2.6 to 6.9 months), and overall survival was 9.8 months (95% CI, 7.4 months to not available). Grade 3 or 4 toxicities included leukopenia/neutropenia, thrombocytopenia, elevation of aminotransferases, and fatigue. Sunitinib rapidly decreased vessel leakiness, and this effect was more pronounced in patients with delayed progression. When evaluated early (at baseline and day 14) as well as over three cycles of treatment, higher levels of inflammatory molecules (eg, interleukin-6, stromal-derived factor 1α, soluble c-KIT) and circulating progenitor cells were associated with a poor outcome.ConclusionSunitinib shows evidence of modest antitumor activity in advanced HCC with manageable adverse effects. Rapid changes in tumor vascular permeability and circulating inflammatory biomarkers are potential determinants of response and resistance to sunitinib in HCC. Our study suggests that control of inflammation might be critical for improving treatment outcome in advanced HCC.

While survival rates for patients with relapsed/refractory osteosarcoma are low, kinase inhibitors have shown efficacy in its treatment. The multikinase inhibitor lenvatinib, plus ifosfamide and etoposide, showed antitumor activity in a Phase II study in patients with relapsed/refractory osteosarcoma. This Phase II randomized controlled trial (OLIE) will assess whether the combination of lenvatinib + ifosfamide + etoposide is superior to ifosfamide + etoposide alone in children, adolescents and young adults with relapsed/refractory osteosarcoma. The primary end point is progression-free survival; secondary and exploratory end points include, but are not limited to, overall survival, objective response rate, safety and tolerability, pharmacokinetic characterization of lenvatinib in the combination treatment, quality of life and quantification of baseline unresectable lesions that are converted to resectable.

Objectives: Previously, no therapeutic agent has been known to improve the overall survival compared with placebo in patients with hepatocellular carcinoma (HCC), who have progressed after sorafenib. In this patient population, regorafenib was first demonstrated to confer a survival benefit in the RESORCE trial, and subsequently it was approved as a second-line treatment for patients with advanced HCC. An open-label expanded access program (EAP) of regorafenib was implemented for compassionate use. We investigated the efficacy and safety of regorafenib based on our experience of the RESORCE trial and the EAP. Methods: Data from 5 patients from the RESORCE trial and 6 from the EAP were analyzed retrospectively. All patients had tolerated prior sorafenib and were progressing during sorafenib treatment. Results: The median progression-free survival was 9.2 months (95% CI 2.3-16.1). One patient achieved a partial response and 7 achieved stable disease. The objective response rate was 9.1%, and the disease control rate was 72.7%. No treatment-associated mortalities were observed. Grade 3 hypophosphatemia was observed in 2 patients, grade 2 anorexia was observed in 5 patients, and grade 3 neutropenia was observed in 2 patients. Grade 2 and grade 3 thrombocytopenia were observed in 2 and 3 patients, respectively. All treatment-related adverse events were improved by reduction or interruption of regorafenib. Five patients showed decreased serum albumin levels. Conclusion: Sorafenib and regorafenib sequential therapy presents a safe and effective treatment option for patients with advanced HCC.

294 Background: A recent ph3 study combining bevacizumab (VEGF-A Mab) with atezolizumab (PD-L1 inhibitor) has shown significant improvements in OS and PFS demonstrating that a combination of VEGF and PDL1 inhibition can improve patient outcomes over sorafenib. Tivozanib (T, a potent and selective VEGFR 1, 2 & 3 TKI) and durvalumab (D, a PD-L1 antibody) have both demonstrated single agent activity in HCC and have been combined safely with other therapies. T blocks all three VEGF receptors, and when combined with a PD-L1 inhibitor may improve patient outcomes. The ph1 portion of this study combines T with D to establish the recommended phase II dose (RP2D) and provide preliminary safety and efficacy data. Methods: Major eligibility criteria are adults with documented advanced HCC, Child-Pugh Class A, ECOG 0 or 1, creatinine clearance > 40 ml/min. Major exclusion criteria are co-infection with HBV and HCV and significant organ dysfunction. The starting dose is the combination of T 1 mg orally for 21 days followed by 7 days off treatment and D 1500 mg intravenously every 28 days. A DLT is generally defined as the occurrence of any Grade ≥3 immune or non-immune adverse event (AE) in Cycle 1 that is at least possibly related to the investigational regimen other than any grade of vitiligo or alopecia or Grade 3 controllable hypertension in cycle 1. The primary objective is to establish the RP2D and the safety and tolerability for this combination in patients with advanced HCC. Patients will be treated until progression of disease, unacceptable side effects, or death. Outcome measures will be AEs per CTCAE v.5 and cross-sectional imaging performed every 8 weeks. Results: Seven patients were enrolled in phase I. Six were male; the median age was 75 (range 40 to 82). One patient had mild elevation of LFTs and did not complete the 21-day course of T and was replaced. No patient experienced a >=grade 3 AE in cycle 1. The most common AEs, each seen in two of seven patients, were anorexia, cough, diarrhea, dysphonia, fatigue, hypertension, and palmar-plantar erythrodysesthesia. Two of seven have achieved a partial response. Conclusions: The combination of T with D in patients with untreated advanced HCC is well tolerated. The RP2D for the combination is T 1 mg orally for 21 days on treatment followed by 7 days off treatment and D 1500 mg intravenously every 28 days. In the phase II portion of the study an additional 30 patients will be treated at the RP2D. Secondary objectives are to assess the objective response rate, progression free survival, and overall survival in this population. Clinical trial information: NCT03970616.

e15573 Background: Over the past few years we have identified tumor-specific frequencies for several common forms of cancer. The goal of this study was to assess the tolerability and effectiveness of electromagnetic fields amplitude-modulated at tumor-specific frequencies and administered by means of an intrabuccal spoon-shaped probe in patients with advanced hepatocellular carcinoma (HCC). Methods: From October 2005 to July 2007, patients with advanced HCC and Child-Pugh A or B were recruited in a phase II study. Three daily 60 min outpatient treatments were administered until disease progression or death. Imaging studies were performed every eight weeks. The primary efficacy end point was progression-free survival ≥ 6 months. Secondary efficacy end points were progression-free survival and overall survival. Results: A total of 41 patients were enrolled, 17 had Child-Pugh A, 20 Child-Pugh B disease. The median age was 64.0 years. Seventeen patients (34.1%) were progression-free for more than 6 months. Median progression-free and overall survivals were 4.8 months (95% CI 2.3–6.0) and 6.9 months (95 CI 4.8–11.1). As of December 2008, four patients are alive and two patients, who are still undergoing therapy, remain progression-free for 30.4 and 30.7 months, respectively. Four patients had partial response (9.8%) and sixteen had stable disease for at least 12 weeks (39.0%) according to the RECIST criteria resulting in 48.8% disease control. All responses were confirmed by independent review. There were no NCI grade 2, 3 or 4 toxicities. One patient developed grade 1 mucositis and one patient grade 1 fatigue. Conclusions: In patients with advanced HCC and impaired hepatic function, treatment with amplitude-modulated electromagnetic fields is safe, well tolerated, and shows evidence of anti-tumor effects, which are long-lasting in some patients. No significant financial relationships to disclose.

4087 Background: The incidence of hepatocellular carcinoma (HCC), a leading cause of cancer death, is increasing with the increasing incidence of chronic liver disease. Sorafenib, the only approved systemic therapy for advanced HCC, provides modest improvement in overall survival. Preclinical studies suggest c-Met is a valid target in HCC, but non-selective TKIs with c-Met inhibitory activity have not shown efficacy in trials, possibly due to lack of c-Met inhibition. Tepotinib (MSC2156119J) is a highly selective c-Met inhibitor that has favorable safety and promising activity, particularly against c-Met+ solid tumors. We report the final results of a phase Ib trial of tepotinib in patients (pts) with advanced HCC. Methods: Pts were Asian adults with confirmed HCC of BCLC Stage C, Child-Pugh Class A liver function without encephalopathy, and ECOG PS 0–2. Pts received tepotinib 300, 500 (the RP2D) or 1,000 mg/day on a 21-day cycle. c-Met expression status was retrospectively determined by IHC. Results: 27 pts were enrolled (median age 57 [38-69]; male 23; ECOG PS 0/1 11/16); 7 received tepotinib 300 mg/day, 14 500 mg/day, and 6 1,000 mg/day (3 with dose reduction). No DLTs were observed. 22 pts experienced treatment-related treatment-emergent adverse events (TRTEAEs), most commonly diarrhea (n = 10), nausea (8), elevated AST (7), and elevated ALT (6). 9 pts had grade ≥3 TRTEAEs, including elevated AST (3) and elevated ALT (3). Best overall response (BOR) was partial response (PR) in 2 pts, one of whom received tepotinib 500 mg (response duration 16.1 months) and one 1,000 mg (4.4 months); both had c-Met+ tumors. A further 8 pts had a BOR of stable disease (SD), 1 pt non-complete response (CR)/non-progressive disease (PD), and 14 pts had PD (2 pts not evaluable). Five pts had progression free survival > 8 months. PK were as expected from previous studies. Conclusions: Tepotinib at doses of up to 1,000 mg/day was well tolerated by Asian pts with advanced HCC and a maximum tolerated dose was not reached. Antitumor activity was observed, particularly in pts with c-Met+ tumors. The ongoing phase II part of this study is comparing the efficacy and safety of first-line tepotinib and sorafenib in pts with c-Met+ HCC. Clinical trial information: NCT01988493.

This study investigated the efficacy and safety of pimasertib (MEK1/MEK2 inhibitor) versus dacarbazine (DTIC) in patients with untreated NRAS-mutated melanoma. Phase II, multicenter, open-label trial. Patients with unresectable, stage IIIc/IVM1 NRAS-mutated cutaneous melanoma were randomized 2:1 to pimasertib (60 mg; oral twice-daily) or DTIC (1000 mg/m2; intravenously) on Day 1 of each 21-day cycle. Patients progressing on DTIC could crossover to pimasertib. Primary endpoint: investigator-assessed progression-free survival (PFS); secondary endpoints: overall survival (OS), objective response rate (ORR), quality of life (QoL), and safety. Overall, 194 patients were randomized (pimasertib n = 130, DTIC n = 64), and 191 received treatment (pimasertib n = 130, DTIC n = 61). PFS was significantly improved with pimasertib versus DTIC (median 13 versus 7 weeks, respectively; hazard ratio (HR) 0.59, 95% confidence interval (CI) 0.42–0.83; p = 0.0022). ORR was improved with pimasertib (odds ratio 2.24, 95% CI 1.00–4.98; p = 0.0453). OS was similar between treatments (median 9 versus 11 months, respectively; HR 0.89, 95% CI 0.61–1.30); 64% of patients receiving DTIC crossed over to pimasertib. Serious adverse events (AEs) were more frequent for pimasertib (57%) than DTIC (20%). The most common treatment-emergent AEs were diarrhea (82%) and blood creatine phosphokinase (CPK) increase (68%) for pimasertib, and nausea (41%) and fatigue (38%) for DTIC. Most frequent grade ≥3 AEs were CPK increase (34%) for pimasertib and neutropenia (15%) for DTIC. Mean QoL scores (baseline and last assessment) were similar between treatments. Pimasertib has activity in NRAS-mutated cutaneous melanoma and a safety profile consistent with known toxicities of MEK inhibitors. Trial registration: ClinicalTrials.gov, NCT01693068.

4589 Background: Sorafenib, a multikinase inhibitor with antiangiogenic activity, has recently been approved for the treatment of unresectable HCC. Combination of sorafenib with metronomic chemotherapy has theoretic advantage in improving antitumor activity without increasing toxicities. UFT (tegafur: uracil = 4:1 in molar ratio), an oral fluoropyrimidine, is active in various gastrointestinal cancers. We conducted a phase II study to evaluate the efficacy and safety of sorafenib plus low-dose UFT in advanced HCC patients (pts). Methods: Pts with histologically or cytologically proven unresectable/metastatic HCC, ECOG PS 0–2, Child-Puch class A, platelets ≥ 100 K/μl, transaminases ≤ 5 × ULN, bilirubin ≤ 3 mg/dl, INR ≤ 2.3 and creatinine ≤ 1.5 × ULN were enrolled. Prior systemic therapy for advanced disease is not allowed. Sorafenib (400 mg bid) and UFT (125 mg/m2 based on tegafur bid) were taken per os continuously. Tumor assessment was performed q8w by RECIST criteria. Primary endpoint is progression-free survival (PFS). Results: Between April 2007 and April 2008, 53 pts were enrolled. Baseline pts characteristics were: M/F, 47/6; median age 57 (range, 31–83); CLIP score 0–3/4, 48/5; extrahepatic spread/macroscopic vascular invasion, 33/30; and HBsAg(+)/anti-HCV(+)/both(+), 38/13/4. 89% of pts were BCLC stage C. Pts received a median of 3.7 (range 0.3- 18.9+) months of treatment. There were 3 (6%) PR and 27 (51%) SD. The median PFS and OS were of 3.7 months (95% C.I., 1.9- 5.5) and 7.4 months (95% C.I., 3.4- 11.4), respectively. Adverse events (AEs) were summarized in Table . Hand-foot skin reaction (HFSR), fatigue, and diarrhea were most common AEs. HFSR was the major AE resulting in dose reduction (19%) or treatment delay (21%). Grade 3/4 neutropenia occurred in 2 pts (4%). Conclusions: Adding metronomic UFT chemotherapy to sorafenib may improve therapeutic efficacy of the latter in pts with advanced HCC. The toxicity profile of the combination is similar to that of sorafenib alone. [Table: see text] [Table: see text]

7100 Background: Amrubicin is a novel anthracycline associated with high objective response rates (ORR) in patients (pts) with relapsed SCLC. Amrubicin improved the ORR and progression-free survival (PFS) in relapsed SCLC vs. topotecan, but not overall survival (OS) in a phase III study. Amrubicin with cisplatin/carboplatin for elderly Japanese pts was safe and active. We conducted a multicenter phase II study evaluating amrubicin and carboplatin in newly diagnosed ES-SCLC. Methods: Eligible pts had untreated ES-SCLC, measurable/evaluable disease (RECIST v. 1.1) and an ECOG PS <2. Pts received 4 cycles of amrubicin 30 mg/m2 on days 1-3 and carboplatin AUC=5 both IV day 1 every 21 days with restaging every 6 weeks. Pegfilgrastim 6 mg sq was administered on day 4 of each cycle. The primary endpoint was 1-year OS. Secondary endpoints included ORR, PFS, OS, and toxicity. Results: 78 pts were enrolled from 3/2010 to 7/2011. Baseline characteristics included: median age 65 yrs (range 45-84); 56% female. 64% completed 4 cycles of treatment. Eleven (14%) pts showed complete responses and 47 (60%) pts partial responses, for an ORR of 74% (95% confidence interval 65%-82%). Twelve (15%) pts had stable disease. Median PFS and OS were 5.3 and 9.5 months, respectively. The 1-year OS was 36%. Grade 3/4 myelosuppression was the most common toxicity (thrombocytopenia 44%, neutropenia 34%, febrile neutropenia 12%, anemia 26%), but was manageable. Severe non-hematologic toxicities (>5%) included hypokalemia 17%, fatigue 13%, dehydration 10%, hyponatremia 10%, pneumonia 9%, and nausea/vomiting 8%. 1 pt died from sepsis and another from aspiration pneumonia. Conclusions: First-line ES-SCLC treatment with amrubicin and carboplatin induced several complete responses and is considered highly active. Myelosuppression was managed effectively with growth factor support. These results are comparable to historical data with platinum-doublet chemotherapy. A larger randomized study would be required to best assess this regimen’s impact on survival.
