4007 Background: Cabozantinib (cabo) is an oral, potent inhibitor of MET and VEGFR2. MET over-expression has been observed in advanced hepatocellular carcinoma (HCC). Anti-VEGF pathway agents have shown clinical benefit in pts w/ HCC. Simultaneous targeting of the MET and VEGF signaling pathways with cabo may therefore be a promising treatment strategy. Methods: Eligible HCC patients (pts) were required to have measurable disease per RECIST, ≤ 1 prior systemic regimen and Child-Pugh score of A. Pts received cabo at 100 mg qd over a 12 wk Lead-in stage. Tumor response (mRECIST) was assessed q6 wks. Treatment ≥ wk 12 was based on response: pts with PR continued open-label cabo, pts with SD were randomized to cabo vs placebo, and pts with PD discontinued. Primary endpoint in the randomized phase was progression free survival (PFS). The primary endpoint was overall response rate (RR) per mRECIST in the Lead-in stage. Results: Enrollment has been completed (n = 41); all pts are unblinded. Median age: 61 years (33 to 83). Males: 76%; Asian: 37%. HCC etiology: Hep B 24%; Hep C 22%; alcohol abuse 20%; other 38%. Extra-hepatic spread observed in 70%. Median number of prior systemic treatments was 1; prior sorafenib was 51%. Median baseline AFP was 368 ng/mL (3 – 259,298); 86% had elevated AFP at baseline. Median follow-up was 5.5 mos (0.8 -18.5). 29 pts (71%) completed the Lead-in stage. Median PFS from Study Day 1 was 4.2 mos. 2/36 pts evaluable for tumor assessment at 12 weeks achieved a confirmed PR (cPR) by original RECIST (RR 5%). One more pt randomized at Week 12 achieved a cPR at 18 weeks. 28/36 pts (78%) with ≥1 post-baseline scan had tumor regression (with no apparent relationship to prior sorafenib therapy). The overall disease control rate (DCR = PR+SD) at Week 12: was 68% (Asian subgroup: 73%). AFP responses (defined as reduction from baseline of >50% in pts with elevated AFP at baseline) in 26 pts with ≥1 post-baseline result: 10/26 (38%). Most common Gr 3/4 AEs: diarrhea (17%), palmar-plantar erythrodyesthesia (15%), and thrombocytopenia (10%). Conclusions: Cabo treatment exhibits activity in HCC pts regardless of prior sorafenib treatment. The safety profile was comparable to that of other VEGFR TKIs.

261 Background: Cabozantinib is an oral, potent inhibitor of MET and VEGFR2. MET over-expression has been observed in advanced hepatocellular carcinoma (HCC). Anti-VEGF pathway agents have shown clinical benefit in pts w/ HCC. Simultaneous targeting of the MET and VEGF signaling pathways with cabozantinib may therefore be a promising treatment strategy. Methods: HCC pts with progressive measurable disease, per mRECIST received cabozantinib at 100 mg qd PO over a 12 week Lead-in period. Up to one prior regimen was allowed and only pts with Child-Pugh score of A were eligible. Tumor response was assessed every 6 weeks. Treatment beyond Week 12 was based on response: pts with PR continued open-label cabozantinib, those with SD were randomized to cabozantinib vs. placebo, and those with PD discontinued study drug. The primary endpoint was overall response rate (RR) per mRECIST in the Lead-in period, and progression free survival for pts who entered the randomized period. Results: Enrollment has been completed with 41 pts. Results are available for 34 pts. Median age: 61 years (33 to 83). Males: 24/34 (71%). Asian: 13/34 (38%). HCC etiology: Hepatitis B or C 12/34 (35%); alcohol abuse 5/34 (15%); other 17/34 (50%). Extrahepatic spread was observed in 21/34 (62%). The median number of prior systemic treatments was 1; prior sorafenib: 16/34 (47%). Most common related AEs ≥Grade 3 were hand-foot syndrome (15%), diarrhea (9%) and thrombocytopenia (9%). 3/33 pts evaluable for tumor assessment at 12 weeks achieved PR by original RECIST (RR 9%). One additional pt randomized at Week 12 achieved PR at 18 weeks and treatment remains blinded on study for >1 year. 24/30 pts (80%) with ≥1 post-baseline scan had tumor regression (with no apparent relationship to prior sorafenib therapy). The overall disease control rate (DCR = PR+SD) at Week 12: 71% (Asian subgroup: 77%). Median time on study: 6 mos (1 to 15+ mos). AFP responses (defined as reduction from baseline of >50%) in 21 pts with ≥1 post-baseline result: 9/21 (43%). Conclusions: Cabozantinib exhibits clinical activity in HCC pts with advanced disease, regardless of prior sorafenib treatment as reflected by tumor reduction, high DCR and time on study.

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.

Abstract Background This open-label, Phase 1b/2 study evaluated the highly selective MET inhibitor tepotinib in systemic anticancer treatment (SACT)-naive Asian patients with advanced hepatocellular carcinoma (aHCC) with MET overexpression. Methods In Phase 2b, tepotinib was orally administered once daily (300, 500 or 1,000 mg) to Asian adults with aHCC. The primary endpoints were dose-limiting toxicities (DLTs) and adverse events (AEs). Phase 2 randomised SACT-naive Asian adults with aHCC with MET overexpression to tepotinib (recommended Phase 2 dose [RP2D]) or sorafenib 400 mg twice daily. The primary endpoint was independently assessed time to progression (TTP). Results In Phase 1b (n = 27), no DLTs occurred; the RP2D was 500 mg. In Phase 2 (n = 90, 45 patients per arm), the primary endpoint was met: independently assessed TTP was significantly longer with tepotinib versus sorafenib (median 2.9 versus 1.4 months, HR = 0.42, 90% confidence interval: 0.26–0.70, P = 0.0043). Progression-free survival and objective response also favoured tepotinib. Treatment-related Grade ≥3 AE rates were 28.9% with tepotinib and 45.5% with sorafenib. Conclusions Tepotinib improved TTP versus sorafenib and was generally well tolerated in SACT-naive Asian patients with aHCC with MET overexpression. Trial registration ClinicalTrials.gov NCT01988493.

Y90 Radioembolization

4590 Background: Nivolumab (N) and Y90-radioembolization (RE) are both therapeutic options in advanced hepatocellular carcinoma (aHCC). Increasing evidence suggests that radiotherapy synergizes with immune checkpoint inhibitors to augment anti-tumour effects. Methods: Eligible Child-Pugh A aHCC patients (pts) were treated with Y90-RE followed by N 240mg, 21 days after Y90-RE and every 2 weeks thereafter. Pre- and on-treatment tumor biopsies together with circulating biomarkers were obtained. Primary end-point was overall response rate (ORR) (per RECIST v 1.1). Overall response was defined as the composite overall response observed for the lesions within Y90-RE field and outside Y90-RE field. Key secondary end points included disease control rate (DCR), progression free survival (PFS), overall survival (OS), and safety. 36 evaluable pts were needed to assess whether the addition of N improved the ORR of Y90-RE from 21% to 41% as determined by Simon two-stage optimal design with 80% power and one sided significance level of 0.05. Results: Forty pts were enrolled of which 36 were evaluable. At baseline: 63.9% were HepB in aetiology; 63.9% BCLC stage C; 47.2% had AFP > 400ng/mL; number of liver lesions – median 5 (range 1- 20); size of largest liver lesion – median 80mm (range 14-177mm); 27.8% had prior TACE; and 13.9% had prior systemic therapy. ORR was 31% (95% CI 16.4 - 48.1%). Eight out of 11 responders had not progressed at study cut-off. DCR was 58.3%. 81% of target lesions within Y90-RE field regressed. With a median follow up of 16.4 months, median PFS and OS were 4.6 months (95% CI 2.3m - 8.4m) and 15.1 months (95% CI 7.8m - NE) respectively. Six- and 12-month PFS rates were 44.2% (95% CI 27.3% - 59.9%) and 26.1% (95% CI 11.2% - 43.8%) respectively. Overall, N+ Y90-RE was well tolerated and safe; only 11% had grade 3/4 treatment related adverse events (AEs). Responders demonstrated significant alterations of LIF, MIG and Eotaxin3 levels in the pre-treatment cytokine analyses. Conclusions: Combination N+Y90-RE resulted in an encouraging ORR of 31% (95% CI 16.4 - 48.1%) in aHCC. 81% of target lesions within Y90-RE field regressed suggesting synergy in combining Y90-RE with nivolumab. This combination is safe and tolerable with low G3/4 treatment related AEs of 11%. Further biomarker analyses will be presented at the meeting. Clinical trial information: NCT03033446 .

End Point

Purpose To determine whether FOLFOX4 (infusional fluorouracil, leucovorin, and oxaliplatin) administered as palliative chemotherapy to patients with advanced hepatocellular carcinoma (HCC) provides a survival benefit and efficacy versus doxorubicin. Patients and Methods This multicenter, open-label, randomized, phase III study in mainland China, Taiwan, Korea, and Thailand involved 371 patients age 18 to 75 years who had locally advanced or metastatic HCC and were ineligible for curative resection or local treatment. They were randomly assigned at a ratio of one to one to receive either FOLFOX4 (n = 184) or doxorubicin (n = 187). The primary end point was overall survival (OS); secondary end points included progression-free survival (PFS), response rate (RR) by RECIST (version 1.0), and safety. Results At the prespecified final analysis, median OS was 6.40 months with FOLFOX4 (95% CI, 5.30 to 7.03) and 4.97 months with doxorubicin (95% CI, 4.23 to 6.03; P = .07; hazard ratio [HR], 0.80; 95% CI, 0.63 to 1.02). Median PFS was 2.93 months with FOLFOX4 (95% CI, 2.43 to 3.53), and 1.77 months with doxorubicin (95% CI, 1.63 to 2.30; P < .001; HR, 0.62; 95% CI, 0.49 to 0.79). RR was 8.15% with FOLFOX4 and 2.67% with doxorubicin (P = .02). On continued follow-up, the trend toward increased OS with FOLFOX4 was maintained (P = .04; HR, 0.79; 95% CI, 0.63 to 0.99). Toxicity was consistent with previous experiences with FOLFOX4; proportions of grade 3 to 4 adverse events were similar between treatments. Conclusion Although the study did not meet its primary end point, the trend toward improved OS with FOLFOX4, along with increased PFS and RR, suggests that this regimen may confer some benefit to Asian patients, but an OS benefit cannot be concluded from these data.

352 Background: Hepatocellular carcinoma (HCC) from alcoholic cirrhosis, associated or not with chronic hepatitis C virus (HCV) infection, is a particularly severe liver disease. Scanty and inconsistent data concerning the efficacy of sorafenib in patients (pts) with this disease are available. Methods: Since February 2009 we screened 26 Child-Pugh liver function class A pts bearing the above characteristics. Sixteen of them (61.5%), 15 males and 1 female with median age of 69 years (range 54-79), received 400 mg sorafenib b.i.d. Predominant cause of HCC was alcohol consumption in 13 pts (81.2%), associated with chronic HCV infection in 2 pts (12.5%), and hemosiderosis in 1 pt (6.2%). All pts suffered from multiple comorbidities, and 3 had been previously treated for Burkitt lymphoma, bladder and breast cancer. One pt with prostate cancer was on treatment with androgen blockade. Median number of concomitant medications was 4 (range 2-9). Four pts never received locoregional treatment, and none had received previous antineoplastic therapy. Results: Twelve pts (73%) discontinued sorafenib after a median time of 2 months (range 2-6). The reasons for treatment discontinuation were disease progression (4 pts), liver function deterioration (5 pts), and mild gastrointestinal adverse events (2 pts): 1 pt refused sorafenib treatment after 15 days. 2/4 patients still on treatment with sorafenib at 7, 8, 11, and 18 months showed partial response (RECIST criteria). Seven pts (40%) died because of disease progression at a median time of 5.5 months (range 2-9) and at a median overall survival time of 36 months from diagnosis (range 2-84). Conclusions: Treatment with sorafenib in pts affected by HCC and alcoholic cirrhosis seems effective and well tolerated with high-level compliance. The most common cause of discontinuation was progression of disease and liver function deterioration. No significant financial relationships to disclose.

8510 Background: RRMM patients (pts) who have exhausted treatment (Tx) with bortezomib (BORT) and lenalidomide (LEN) or thalidomide have a poor prognosis with short overall survival (OS). HiDEX is a well-established standard Tx in RRMM. POM has demonstrated clinical efficacy in pts refractory to LEN and BORT. MM-003 compared POM + LoDEX vs. HiDEX in RRMM pts who failed LEN and BORT and who progressed on their last Tx. Methods: Pts must have been refractory to last prior Tx (progressive disease [PD] during Tx or within 60 days) and failed LEN and BORT after ≥ 2 consecutive cycles of each (alone or in combination). Pts were randomized 2:1 to receive 28-day cycles of POM 4 mg D1–21 + DEX 40 mg (20 mg for pts aged > 75 y) weekly or DEX 40 mg (20 mg for pts aged > 75 y) D1–4, 9–12, and 17–20. Tx continued until PD or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Secondary endpoints included OS, overall response rate (ORR; ≥ partial response), and safety. Analyses were based on intent to treat. Results: 455 pts were randomized to POM + LoDEX (n = 302) or HiDEX (n = 153). The median number of prior Tx was 5 (range 1-17). 72% were refractory to LEN and BORT. Median follow-up was 4 months. POM + LoDEX significantly extended median PFS (3.6 vs. 1.8 months, HR = 0.45, P < .001) and OS (not reached vs. 7.8 months, HR = 0.53, P < .001) vs. HiDEX. The OS benefit was observed despite 29% of HiDEX pts receiving POM after PD. The trial met the primary endpoint of PFS, crossed the upper boundary for OS superiority, and the Data Monitoring Committee recommended crossover from HiDEX to POM ± DEX. With updated data, the ORR was 21% for POM + LoDEX vs. 3% for HiDEX (P < .001) and 24% vs 3% for pts randomized ≥ 6 months post-enrollment (P < .001). The most frequent grade 3/4 adverse events (AEs) for POM + LoDEX vs. HiDEX were neutropenia (42% vs. 15%), anemia (27% vs. 29%), and infection (24% vs. 23%). Discontinuation due to AEs was infrequent (7% vs. 6%). Updated data will be presented. Conclusions: POM + LoDEX significantly extended PFS and OS vs. HiDEX in pts who failed LEN and BORT. POM + LoDEX should become a standard of care in RRMM pts who have exhausted Tx with LEN and BORT. Clinical trial information: NCT01311687.

5043 Background: The survival benefit of D in mCRPC is modest. CDK4/6 inhibitors such as R have shown synergistic activity with taxanes in pre-clinical cancer models. We sought to determine the safety and efficacy of R + D + P in mCRPC patients (pts). Methods: This was a Ph 1b/2 multicenter, open-label single arm trial of mCRPC pts with progression (PD) on ≥ 1 prior androgen receptor signaling inhibitor (ARSi) who had not previously received D for mCRPC (NCT02494921). Pts were treated with escalating doses of R in combination with D + P for 6-9 cycles, followed by single agent maintenance R until radiographic or clinical PD. The Ph 2 primary endpoint was 6-month (mo) radiographic progression-free survival (rPFS) rate by PCWG2 criteria, with a target rate of 55% and null hypothesis of 35%. Ph 2 pts underwent baseline circulating tumor cell (CTC) enumeration and genome sequencing (Epic Sciences). Cox proportional hazard model and log-rank test were used to test for associations between rPFS and CTC burden and copy number (CN) variants, respectively. Results: 43 pts were enrolled from 11/2015 to 6/2019. Median age was 68 (range 55-84). 20.9% of pts had visceral metastases. 33 (77%) had PD on prior abiraterone, 27 (63%) on enzalutamide, and 17 (40%) on both. In Ph 1b, 19 pts were enrolled. In the first cohort (D 75 mg/m2 day [d] 1, R 200 mg/d d2-14 of every 21d cycle), 2 pts experienced DLTs (febrile neutropenia [FN] and grade 4 neutropenia). With an alternative dosing schema of D 60 mg/m2 on d1, and R daily on d1-4 and 8-15 of cycle, with daily G-CSF support on d5-7, the MTD was not reached and D 60 mg/m2 + R 400 mg/d was chosen as the recommended Ph 2 dose (RP2D). In total, 30 pts were treated at RP2D; median number of D cycles was 8.5 and 60% went on to receive maintenance R. The Ph 2 primary endpoint was met with a 6-mo rPFS rate of 65% (95% CI 50-85%). Median rPFS was 8.0 mos (95% CI 4.1-10.0). PSA response rate (RR) defined as ≥50% reduction was 27.6% (95% CI 12.7-47.2%) and objective RR was 30.8% (95% CI 9.1-61.4%). Among pts treated at RP2D, the most common grade ≥3 treatment-related adverse events were neutropenia (n= 11, 36.7%), lymphocytopenia (n=3, 10%); no cases of FN were observed. Baseline CTC burden was associated with an increased risk of radiographic PD or death (HR 1.038, 95% CI 1.001-1.074, p = 0.038). Pts harboring CTCs without MYC (4/11 pts) or CDK6 CN gain (7/11 pts) had prolonged rPFS compared to those with gene amplification (median rPFS 10.76 vs 4.11 mos, p = 0.03, and 7.01 vs 1.92 mos, p = 0.053, respectively). Conclusions: The combination of R + D was well tolerated and showed promising activity in mCRPC pts who had progressed on an ARSi. The Ph 2 study met its primary endpoint, with an encouraging 6-mo rPFS rate of 65%. Lack of MYC or CDK6 amplification on CTC sequencing was associated with longer rPFS.

Abstract Purpose: This study aimed to assess efficacy and safety of anlotinib as a first- or second-line treatment for advanced or metastatic hepatocellular carcinoma (aHCC) and to identify the predictive plasma cytokines on efficacy of anlotinib.Methods: It was a phase II clinical study. Patients with aHCC were recruited from October 2016 to April 2019 and divided into two cohorts according to previous tyrosine kinase inhibitors (TKIs) therapy. Those without or with prior TKIs were in Cohort 1 or 2, respectively. All patients took anlotinib (12mg/day, Day1–14, three weeks per cycle). The primary endpoint was 12-week progression free survival (PFS) rate. Relationship between series plasma cytokine level and efficacy of anlotinib was analyzed.Results: Enrolled 26 patients in Cohort 1 and 24 in Cohort 2. In Cohort 1, the 12-week PFS rate was 80.8% (95% confidence interval [CI]; 59.8%–91.5%) and median time to progression (TTP) was 5.9 months (95% CI; 4.8–6.9). In Cohort 2, the 12-week PFS rate and median TTP was 72.5% (95% CI; 48.7%–86.6%) and 4.6 months (95% CI; 2.7–10.0), respectively. The median TTP on patients with baseline plasma level of CXCL1 (C-X-C motif chemokine ligand 1) less than 7.6 ng/μl was significant longer in both cohorts. The most common grade 3–5 adverse events were hypertension (8%), diarrhea (8%) and hand-foot syndrome (6%). Conclusion: Anlotinib showed promising efficacy and safety as a first- or second-line treatment with a continuous TKIs treatment strategy in aHCC.

Background: Mipsagargin (G-202) is a thapsigargin-based prodrug with cytotoxic activity masked by a peptide that is cleaved by prostate-specific membrane antigen (PSMA), a protease expressed in prostate cancer cells and the endothelium of tumor vasculature. It was hypothesized that PSMA-mediated activation of mipsagargin would result in disruption of the tumor vasculature, leading to a decrease in blood flow, and in direct cytotoxic effects on tumor cells, resulting in anti-tumor activity. Method: In this open-label, Phase II study, mipsagargin was administered intravenously on Days 1, 2, and 3 of a 28-day cycle to patients with hepatocellular carcinoma (HCC) who progressed on or after treatment with sorafenib or intolerant of sorafenib. Assessments included time to disease progression (TTP), response rate, progression-free survival (PFS), overall survival (OS), and safety. Blood flow metrics in hepatic lesions were evaluated using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Results: Of 25 treated patients, 19 were evaluable for efficacy. None had an objective response, 12 (63.2%) had a best response of stable disease, and 12 (63.2%) showed radiologic progression; seven patients (36.8%) were censored. The median TTP was 134.0 days, median PFS was 129.0 days, and median OS was 205.0 days. Of five patients with DCE-MRI data for 11 HCC lesions, all demonstrated a reduced Ktrans (mean, 52%). The most common treatment-emergent AEs were Grade 1–2 and consisted of increased blood creatinine (68.0%), fatigue (56.0%), and nausea (44.0%). Conclusions: Mipsagargin is relatively well tolerated and promotes prolonged disease stabilization in patients with advanced HCC that had progressed on prior treatment with sorafenib. A significant decrease in Ktrans upon treatment suggests mipsagargin reduces blood flow in hepatic lesions.
