TPS4595 Background: Most RCCs contain clear cell histology; the remainder of cases are summarized as nccRCC. nccRCC is a heterogeneous group of tumors and, with advanced metastases, survival is uniformly worse than with clear cell RCC (ccRCC) because of the aggressiveness of these cancers and a lack of effective systemic treatment options. Because data are limited for patients with nccRCC, the role of various agents in the treatment of nccRCC is poorly defined and there is no standard of care; treatment guidelines recommend clinical trials as preferred strategy. Inhibition of the PD-1/PD-L1 pathway is an effective treatment option for nccRCC, and pembrolizumab monotherapy has shown efficacy with an acceptable safety profile as first-line treatment. The VEGF TKI lenvatinib has also shown efficacy with a tolerable safety profile as combination therapy with everolimus for nccRCC. Also, in the phase 3 KEYNOTE-581 study (NCT02811861), the combination of lenvatinib + pembrolizumab as first-line therapy showed antitumor activity in patients with metastatic ccRCC, suggesting this combination might be an excellent therapeutic option for nccRCC. The phase 2, open-label, single-arm, KEYNOTE-B61 study (NCT04704219) is being conducted to evaluate pembrolizumab in combination with lenvatinib as first-line treatment for nccRCC. Methods: Patients with centrally confirmed nccRCC, locally advanced/metastatic measurable disease per RECIST v1.1 per blinded independent central review (BICR), no prior systemic therapy for nccRCC, and KPS score ≥70 will be enrolled. Approximately 152 patients will receive pembrolizumab 400 mg every 6 weeks and lenvatinib 20 mg once daily. Pembrolizumab treatment will continue for up to approximately 2 years or until a discontinuation criterion is met (disease progression, unacceptable toxicity, or withdrawal of consent); lenvatinib treatment can continue beyond 2 years or until one of the same discontinuation criterion is met. Participants who discontinue one of the treatments can continue to receive the other treatment as monotherapy. A second-course treatment phase is available for patients who meet specific criteria. CT/MRI will be performed at 12 weeks from the start of treatment, every 6 weeks until week 54, and every 12 weeks thereafter. Adverse events will be monitored throughout the study and graded using CTCAE, version 5.0, guidelines. The primary end point is objective response rate based on RECIST v1.1 per BICR. Secondary efficacy end points for this study are clinical benefit rate, disease control rate, duration of response, progression-free survival, overall survival, and safety. Tertiary/exploratory end points are biomarker analysis and association with clinical response/disease etiopathogenesis. Clinical trial information: NCT04704219.

e16213 Background: Currently nab-paclitaxel/gemcitabine (AG) is the standard first-line treatment for advanced pancreatic ductal adenocarcinoma (aPDAC), which is still needed to improve. The phase Ib/II study aiming to evaluate safety and efficacy of AG plus toripalimab, an anti-PD-1 monoclonal antibody, showed well tolerability and encouraging efficacy in aPDAC patients (preliminary data presented at 2020 ASCO). Here, we updated new results of this study. Methods: This was a single-arm, open-label, phase Ib/II clinical trial of AG with toripalimab as first-line treatment for aPDAC. Patients received toripalimab (240mg, Q3W), combined with AG (nab-paclitaxel 125 mg/m2, d1, d8 plus gemcitabine 1000 mg/m2, d1, d8) until the disease progresses/unacceptable toxicity or receiving toripalimab maintenance treatment. The primary objectives were safety and OS; the secondary objectives were ORR, DCR and PFS. Predictive biomarkers including MMR protein and PD-L1 expression, the tumor mutation burden (TMB) based on next-generation sequencing, genomic alteration signatures and the number of TILs were evaluated. Results: At data cutoff (Feb 3, 2021), 20 chemotherapy naïve aPDAC patients (female: 65.0%, median age: 55.5 years) with ECOG PS ≤ 2 were enrolled. Of the 17 evaluable patients, the ORR was 35.3%, the DCR was 82.4%, including 5 patients with PR and 1 patient with CR, respectively. 12 patients were alive and the study treatments for 9 patients were still ongoing. Median PFS was 5.0 months (95% CI：4.216-5.784), the 6-month PFS rate was 60%; median OS was 14.0 months (95% CI：9.445-18.555), the 1-year OS rate was 80%. 2 cases of pseudoprogression were observed. The most frequent treatment related adverse events were ALT elevation (35.0%), leukocytopenia (30.0%) metabolic disorder (25.0%) and hypothyroidism (25.0%). 4 patients (20.0%) experienced grade 3/4 TRAE (including myocardial enzyme elevation, neutropenia, vomiting and nausea). In the biomarker analysis, all patients were MMR-proficient status; 14 patients were evaluated for PD-L1 expression compared with PD-L1 negative cases (n = 5), PD-L1 positive cases (n = 9) did not show higher RR or longer PFS, responses were observed in both groups. 10 patients were investigated for NGS, 2 patients with TMB > 10 Muts/Mb, the most frequently mutated genes were KRAS (90%), TP53 (90%) and ARID1A (20%). Conclusions: The updated results of this phase Ib/II study provided preliminary evidence that toripalimab in combination with AG has a manageable safety profile consistent with known safety profile for each agent alone and demonstrates signals of clinical activity. The correlation between biomarkers with clinical efficacy are under investigation. The results supported ongoing combined treatment in aPDAC patients. Clinical trial information: ChiCTR2000032293.

Abstract Introduction: Treatment of CLL has advanced tremendously in the past decade with significant extension of life expectancy in patients diagnosed with the disease. Three anti-CD20 monoclonal antibody (mAB) combinations approved for previously untreated chronic lymphocytic leukemia (CLL) patients are obinutuzumab-chlorambucil (OBI-CHL), ofatumumab-chlorambucil (OFA-CHL), and rituximab-chlorambucil (RTX-CHL), have comparable efficacy but varying safety profiles in pivotal trials. Grade 3-4 adverse events (AEs), including infusion-related reactions (IRRs), neutropenia, thrombocytopenia, anemia, and infections differ by each mAB. Grade 3-4 AEs, defined as requiring hospitalization or life-threatening, result in reductions in patient quality of life (QoL) and bear cost implications. We sought to compare the safety of the IV-administered anti-CD20 mABs in the first-line treatment of CLL and to evaluate the respective QoL and economic implications of these AEs. Methods: A systematic literature review was conducted in PubMed, Embase, and Cochrane library for the time period of 2010-2016 and in conference proceedings of ASH, the American Society of Clinical Oncology (ASCO), and the European Hematology Association (EHA) for 2014-2016. Search was limited to clinical trials conducted on humans and published in English language. The IRRs were compared directly as CHL is administered orally. A Bayesian network meta-analyses (NMA) was conducted with data from phase 3 trials using SAS® (v9.3) to compare grade 3-4 neutropenia, thrombocytopenia, anemia, and infections associated with the three anti-CD20 mABs. A pooled analysis of data from phase 2 trials and cohort studies was conducted using MedCalc® version 16.2.1. Analyses were also conducted to estimate the potential impact of the AEs of respective anti-CD20 mABs on QoL and cost of care based on the NMA results and previously published estimates of utilities associated with CR (0.780), PR (0.790), SD/PD (0.760); disutilities associated with IRR (-0.11), neutropenia (-0.09), thrombocytopenia (-0.05), anemia (-0.09), and infections (-0.20); and costs associated with episodes of IRR ($4,482), neutropenia ($5,406), thrombocytopenia ($12,621), anemia ($8,894), and infections ($7,163) in CLL. Results: Of the 86 studies screened, 10 studies were included. Direct comparison showed that the rate of IRRs in OBI-CHL, OFA-CHL, and RTX-CHL were 21%, 10%, and 4%, respectively. Risks for neutropenia were lower for OFA-CHL compared to OBI-CHL (OR = 0.74; 95% CI: 0.12-4.59) and similar to RTX-CHL (1.08; 0.20-5.82); for thrombocytopenia were lower for OFA-CHL compared to OBI-CHL (0.16; 0.02-1.33) and to RTX-CHL (0.49; 0.06-4.15); for anemia were lower for OFA-CHL compared to OBI-CHL (0.80; 0.21-3.06) and similar to RTX-CHL (1.08; 0.24-4.64); and for infections OFA-CHL, OBI-CHL (1.00; 0.15-6.74) and RTX-CHL (0.86; 0.15-4.43) were similar. The pooled analyses of AEs observed in phase 2 / cohort studies revealed similar trends when assessed. The mean pre-progression QoL utilities associated with OBI-CHL, OFA-CHL, and RTX-CHL weighted by rates of AEs, utilities associated with respective response rates to treatments, and disutilities of the respective AEs were 0.772, 0.761, and 0.748 respectively. The total cost of treating AEs per 1,000 patients on OFA-CHL, OBI-CHL and RTX-CHL were $3.9M, $8.0M and $4.2M, respectively. Conclusion: The safety profile was most desirable for OFA-CHL, followed by RTX-CHL and OBI-CHL. Though RTX-CHL had the lowest rate of grade 3-4 IRR, OFA-CHL had the better grade 3-4 hematologic safety profile compared to OBI-CHL and RTX-CHL. As efficacy of CLL treatments has improved substantially, safety of treatments is increasingly important particularly on the impact of QoL. In addition, in the cost-conscious payer environment, selecting drugs with a better safety profile and lower cost implications is vital. Our findings demonstrate that better safety profile is associated with less impact on QoL and lower costs. We found that for every 1,000 patients covered by a payer, safety alone can save an excess of $4M based on regimen choice. Fewer incidences of AEs also results in better adherence and reduction in treatment interruption or discontinuation. Safety with the QoL and cost implications should be taken into consideration to maximize the overall benefits of the treatment to CLL patients.

270 Background: Sorafenib is the standard first line treatment for advanced HCC and showed a median time to progression (TTP) of 5.5 months and an overall response rate (ORR) of 2% in the phase III SHARP trial. FOLFOX has shown modest activity in HCC with a progression free survival (PFS) of 2.9 months and ORR of 8% in a phase III trial. In this single-arm, multicenter phase 2 and biomarker study, sorafenib plus FOLFOX was evaluated in the first line treatment of advanced HCC. Methods: Patients with histologically proven advanced HCC, Child Pugh A liver function, and no prior systemic therapies received sorafenib 400mg orally twice daily during a 2-week lead-in, followed by concurrent modified FOLFOX (5-FUCI 1200mg/m2/day for 46 hours and LV 400mg/m2 bolus, Oxaliplatin 85mg/m2) on day 1 and 15 of each 28-day cycle. The primary endpoint was TTP, calculated from date of study entry to date of radiological or clinical disease progression. Serial plasma anti-angiogenic and anti-inflammatory biomarkers were evaluated. Results: The study enrolled 40 patients with advanced HCC: median age, 65 years; male 85%; Child Pugh A5, 70%; BCLC stage C, 95%; HCC etiology, HCV 40%, HBV 13%, alcohol 13%. Grade 3/4 adverse events were notable for AST (23%), ALT (15%), bilirubin (10%), diarrhea (10%), anemia (10%), hypertension (5%), hand-foot syndrome (5%), and thrombocytopenia (5%). Dose reductions for sorafenib and FOLFOX were done in 73% and 65% of patients, respectively. The median TTP was 8.8 months (95%CI, 6.5-11.2). The ORR was 18%, and the stable disease rate was 55%. Among 36 patients with a baseline AFP ≥ 5 ng/mL, 10 (28%) had a ≥ 50% drop in AFP. Low baseline plasma levels of sVEGFR1, VEGF-C, and bFGF and high levels of s-cMET and IL-12 tended to associate with longer TTP (p < 0.10). Decreased s-cMET at day 15 and decreased s-cMET and IL-2 at day 43 were associated with longer TTP (p < 0.05). Conclusions: Sorafenib+FOLFOX demonstrated encouraging clinical efficacy with moderate toxicity in the first line treatment of advanced HCC. Initial biomarker evaluation suggested a correlation between TTP and baseline angiogenic markers as well as changes in IL-2 and s-cMET. Complete biomarker analysis will be presented at the meeting. Clinical trial information: NCT01775501.

TPS4143 Background: Blockade of the immune checkpoint receptor programmed death-1 (PD-1) has shown clinical benefit in multiple tumor types. Nivolumab (anti–PD-1) has demonstrated a survival advantage versus (vs) placebo in patients (pts) with advanced gastric cancer (GC) or gastroesophageal junction cancer (GEJC) (Kang YK et al. Lancet 2017;390:2461–71). Lymphocyte activation gene 3 (LAG-3) is an immune checkpoint molecule that negatively regulates effector T-cell function and is a marker of T-cell exhaustion. Preliminary data in melanoma suggest that combining nivolumab with relatlimab (anti–LAG-3) could improve efficacy without substantially increasing toxicity vs nivolumab especially, but not exclusively, in LAG-3-expressing pts (Ascierto PA et al. Ann Oncol 2017;28(S5):LBA18). Furthermore, LAG-3 expression was as high as 33% in an analysis of solid tumors including GC (Edwards R et al. J Immunother Cancer 2017;5(S3):P510). Study CA224-060 will assess the clinical efficacy and safety of relatlimab and nivolumab with chemotherapy for first-line treatment of GC or GEJC. Methods: This is a randomized, open-label, multicenter, phase 2 study of relatlimab and nivolumab with oxaliplatin-based chemotherapy vs nivolumab with oxaliplatin-based chemotherapy. Approximately 250 adult pts with untreated, locally advanced, unresectable or metastatic GC or GEJC will be enrolled. To be randomized, pts must have tumor tissue for analysis of biomarkers, LAG-3 status, and PD-L1 combined positive score. Key exclusion criteria include HER2-positive status, untreated CNS metastases, or significant cardiovascular disease. The primary endpoint is objective response rate (ORR) using RECIST v.1.1 by blinded independent central review in LAG-3-expressing pts. Other endpoints include investigator-assessed ORR, ORR in LAG-3-negative pts, duration of response, overall survival, progression-free survival, and safety and tolerability. Efficacy signals in biomarker subgroups will be explored. Currently, 26 sites are activated with 15 randomized pts. Clinical trial information: NCT03662659.
