TPS4143 Background: The tyrosine kinase inhibitor sorafenib is the standard of care for first-line HCC; currently, there is no clear standard of care after disease progression on sorafenib or for patients (pts) with intolerance to sorafenib. Because most HCC is driven by inflammation, there is a strong rationale to evaluate immunotherapy in pts with this type of cancer. The randomized, double-blind, placebo-controlled phase 3 KEYNOTE-240 study (ClinicalTrials.gov, NCT02702401) was designed to compare the efficacy and safety of the anti–PD-1 antibody pembro + BSC vs placebo + BSC in pts with previously treated advanced HCC. Methods: Eligibility criteria include age ≥ 18 years, histologically or cytologically confirmed diagnosis of HCC, documented progression after stopping treatment with sorafenib or intolerance to sorafenib, disease not amenable to a curative treatmentapproach (eg, transplantation, surgery, or ablation), measurable disease confirmed by central imaging vendor review per RECIST v1.1, Child-Pugh liver score A, ECOG performance status 0-1, and predicted life expectancy > 3 months. Pts will be randomly assigned 2:1 to receive pembro 200 mg IV Q3W + BSC or placebo Q3W + BSC for up to 35 cycles (~2 years) or until disease progression, unacceptable toxicity, or investigator decision. Randomization will be stratified by geographic region, presence of macrovascular invasion, and α-fetoprotein level. BSC will be provided by the investigator per local treatment practices. Response will be assessed every 6 weeks per RECIST v1.1 by central imaging vendor review. Adverse events (AEs) will be assessed throughout treatment and for 30 days thereafter (90 days for serious AEs) and graded per NCI CTCAE v4.0. Primary objectives are comparison of progression-free survival per RECIST v1.1 by central imaging vendor review and overall survival between treatment arms. Secondary objectives are comparison of objective response rate, duration of response, disease control rate, and time to progression per RECIST v1.1 by central imaging vendor review; and evaluation of safety and tolerability. Planned enrollment in KEYNOTE-240 is 408 pts across 26 countries. Clinical trial information: NCT02702401.

TPS504 Background: The tyrosine kinase inhibitor sorafenib is the standard of care for first-line hepatocellular carcinoma (HCC). For patients with HCC after disease progression on sorafenib or for those with intolerance to sorafenib, no approved therapies are available. Because HCC is often driven by inflammation and is also associated with a suppressed immunoenvironment, there is a strong rationale to evaluate immunotherapy in patients with this type of cancer. The single-arm, multisite, phase 2 KEYNOTE-224 study (ClinicalTrials.gov, NCT02702414) was designed to evaluate the efficacy and safety of the anti–PD-1 antibody pembrolizumab in patients with previously treated advanced HCC. Methods: Approximately 100 patients will be enrolled. Inclusion criteria include age ≥18 years, histologically or cytologically confirmed diagnosis of HCC Barcelona Clinic Liver Cancer (BCLC) stage C disease or BCLC stage B disease not amenable to or refractory to locoregional therapy, and disease not amenable to a curative treatment approach (eg, transplantation, surgery, or ablation). Patients must also have measurable disease based on RECIST v1.1 as confirmed by central imaging vendor review, documented objective radiographic progression after stopping treatment with sorafenib or intolerance to sorafenib, Child-Pugh liver score A, ECOG performance status 0-1, and predicted life expectancy > 3 months. Patients will be allocated to receive pembrolizumab 200 mg IV every 3 weeks for up to 35 cycles (~2 years) or until disease progression, unacceptable toxicity, patient withdrawal of consent, or investigator decision. Response will be assessed every 9 weeks per RECIST v1.1 by central imaging vendor review. Adverse events (AEs) will be assessed throughout treatment and for 30 days thereafter (90 days for serious AEs) and graded per NCI CTCAE v4.0. The primary end point is objective response rate per RECIST v1.1 by central imaging vendor review. Secondary end points are overall survival; safety and tolerability; and duration of response, disease control rate, time to progression, and progression-free survival per RECIST v1.1 by central imaging vendor review. Enrollment in KEYNOTE-224 is ongoing. Clinical trial information: NCT02702414.

TPS503 Background: There are no approved therapies for patients with hepatocellular carcinoma (HCC) after disease progression on sorafenib, or for patients with intolerance to sorafenib. HCC often arises in the background of chronic inflammation and is also associated with an immunosuppressed microenvironment, providing a strong rationale to evaluate immunotherapy in HCC. The randomized, double-blind, placebo-controlled phase 3 KEYNOTE-240 study (ClinicalTrials.gov, NCT02702401) was designed to compare the efficacy and safety of the anti–PD-1 antibody pembrolizumab + best supportive care (BSC) vs placebo + BSC in patients with previously treated advanced HCC. Methods: Eligibility criteria include age ≥18 years, confirmed diagnosis of Barcelona Clinic Liver Cancer (BCLC) stage C disease or BCLC stage B disease not amenable to or refractory to locoregional therapy, disease not amenable to a curative treatment approach (eg, transplantation, surgery, or ablation), documented progression after treatment with sorafenib or intolerance to sorafenib, Child-Pugh liver score A, and ECOG performance status 0-1. ~408 patients will be randomly assigned 2:1 to receive pembrolizumab 200 mg IV every 3 weeks (Q3W) + BSC or placebo Q3W + BSC for up to 35 cycles or until disease progression, unacceptable toxicity, patient withdrawal of consent, or investigator decision. Randomization will be stratified by geographic region, macrovascular invasion, and α-fetoprotein. BSC will be provided by the investigator per local treatment practices. Response will be assessed every 6 weeks per RECIST v1.1 by central imaging vendor review.

6001 Background: Cabozantinib (C), an inhibitor of VEGFR2, MET, AXL, and RET, showed clinical activity in patients (pts) with radioiodine (RAI)-refractory differentiated thyroid cancer (DTC) in phase 1/2 studies (Cabanillas 2017; Brose 2018). This phase 3 study (NCT03690388) evaluated the efficacy and safety of C vs placebo (P) in pts with RAI-refractory DTC who had progressed during/after prior VEGFR-targeted therapy for whom there is no standard of care. Methods: In this double-blind, phase 3 trial, pts were randomized 2:1 to receive C (60 mg QD) or P, stratified by prior lenvatinib treatment (L; yes, no) and age (≤65, > 65 yr). Pts with RAI-refractory DTC must have received L or sorafenib for DTC and progressed during or following treatment with ≤ 2 prior VEGFR inhibitors. Pts randomized to P could cross over to open-label C upon disease progression per blinded independent radiology committee (BIRC). The primary endpoints were objective response rate (ORR) in the first 100 randomized pts and progression-free survival (PFS) in all randomized pts. PFS and ORR were assessed by BIRC per RECIST v1.1. The study was designed to detect an ORR for C vs P (2-sided α = 0.01) and a hazard ratio (HR) for PFS of 0.61 (90% power, 2-sided α = 0.04). A prespecified interim PFS analysis was planned for the ITT population at the time of the primary ORR analysis. Results: As of 19 Aug 2020,125 vs 62 pts had been randomized to the C and P arms, respectively; median age was 66 yr, 55% were female and 63% received prior L. Median (m) follow-up was 6.2 months (mo). At the planned interim analysis, the trial met the primary endpoint of PFS with C demonstrating significant improvement over P (HR 0.22, 96% CI 0.13–0.36; p < 0.0001). mPFS was not reached for C vs 1.9 mo for P; PFS benefit was observed in all prespecified subgroups including prior L (yes, HR 0.26; no, HR 0.11) and age (≤65 yr, HR 0.16; > 65 yr, HR 0.31). ORR was 15% for C vs 0% for P (p = 0.0281) but did not meet the prespecified criteria for statistical significance (p < 0.01). A favorable OS trend was observed for C vs P (HR 0.54, 95% CI 0.27–1.11). Treatment-emergent adverse events (AEs) of any grade with higher occurrences in the C vs P arm included diarrhea (51% vs 3%), hand-foot skin reaction (46% vs 0%), hypertension (28% vs 5%), fatigue (27% vs 8%), and nausea (24% vs 2%); grade 3/4 AEs were experienced by 57% of pts with C vs 26% with P. Dose reductions due to any grade AEs occurred in 57% of pts with C vs 5% with P. Treatment discontinuations due to AEs not related to disease progression occurred in 5% of pts with C vs 0% with P. No treatment-related deaths occurred in either arm. Conclusions: C showed a clinically and statistically significant improvement in PFS over P in pts with RAI-refractory DTC after prior VEGFR-targeted therapy with no unexpected toxicities. C may represent a new standard of care in pts with previously treated DTC. Clinical trial information: NCT03690388.

9500 Background: The phase 3 double-blind EORTC 1325/KEYNOTE-054 trial evaluated pembrolizumab (pembro) vs placebo in stage III cutaneous melanoma patients (pts) with complete resection of lymph nodes. Pembro improved RFS (hazard ratio [HR] 0.57) and DMFS (HR 0.60) (Eggermont, NEJM 2018, TLO 2021). In the pembro group, the incidence of immune related AE (irAE) grade 1-5 was 37%, and of grade 3-5 was 7%. We present the safety profile, response rate and PFS for the subset of pts who had a recurrence and crossed over or were rechallenged with pembrolizumab, within protocol. Methods: Pts were randomized to receive iv. pembro 200 mg (N=514) or placebo (N=505) every 3 weeks for a total of 18 doses (~1 year). Upon recurrence with no brain metastases, pts with an ECOG PS 0-2 were eligible to enter part 2 of the study, i.e. to receive pembro 200 mg iv. every 3 weeks for a maximum of 2 years, for crossover (those who received placebo) or rechallenge (those who recurred ≥6 months after completing one year of pembro therapy). Treatment was stopped in case of disease progression (RECIST 1.1) or unacceptable toxicity. Results: At the clinical cut-off (16-Oct-2020), 298 (59%) pts had a disease recurrence in the placebo group; 155 pts participated in the crossover part 2 of the trial. A total of 297 (58%) pts completed the 1-yr pembro adjuvant treatment, of whom 47 had a recurrence ≥6 mths from the stop of treatment and 20 entered in the rechallenge part of the trial. Among 175 pts who started pembro in Part 2, 160 discontinued due to completion of therapy (N=24), disease progression (N=88), toxicity (N=20), investigator's decision (N=21), or other reason (N=7); 15 pts were still on-treatment. Results for the 2 groups are provided in the table. The median number of doses was 12 and 5.5, respectively (resp), and the median follow-up was 41 and 19 mts, resp. Among the 175 pts, 51 (29%) had a grade 1-4 irAE (by group: 47 [30%] and 4 [20%] resp) and 11 (6%) a grade 3-4 irAE. Conclusions: Pembrolizumab treatment after crossover yielded a 39% ORR in evaluable pts and an overall 3-yr PFS of ̃32%, but after rechallenge the efficacy was lower. Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA The median PFS (95% CI) from start of Part 2 was 14 (5-27) and 8 (5-15) mts for stage III-resected and III/IV various, resp. Among the 80 stage IV crossover pts with evaluable disease, 31 (39%) had an objective response: 14 (18%) CR, 17 (21%) PR. The 2-yr PFS rate from response was 69% (95% CI 48-83%). For these 80 pts, the median PFS was 6.1 mts and the 3-yr PFS rate was 31% (95% CI 21-41%). Among 9 stage IV rechallenged pts with an evaluable disease, 1 (11%) reached CR, 3 had SD and 5 PD. Clinical trial information: NCT02362594. [Table: see text]

6012 Background: EAGLE is a phase 3 study evaluating efficacy of D (anti-PD-L1 mAb) monotherapy and D+T (anti-CTLA-4 mAb) vs standard of care (SOC) in pts with R/M HNSCC who progressed following platinum-based therapy (NCT02369874). Methods: Pts were randomized 1:1:1 to D 10 mg/kg IV every 2 weeks (Q2W), D+T (D 20 mg/kg IV Q4W + T 1 mg/kg IV Q4W for 4 doses, then D 10 mg/kg IV Q2W), or SOC (investigator’s choice: cetuximab, taxane, methotrexate, or fluoropyrimidine-based regimen). The primary endpoint was overall survival (OS) with dual primary objectives of D+T vs SOC and D vs SOC. Additional endpoints included objective response rate (ORR), duration of response (DoR), and adverse events (AEs). Results: 240 pts were randomized to D, 247 to D+T and 249 to SOC. An imbalance for Eastern Cooperative Oncology Group performance status (ECOG PS) was seen in favor of the SOC arm (D, PS 0 = 26%, PS 1 = 74%; D+T, PS 0 = 26%, PS 1 = 74%; SOC, PS 0 = 32%, PS 1 = 68%). The risk of death was not statistically significantly different for D compared with SOC (HR: 0.88; 95% CI: 0.72–1.08; P = 0.20) or D+T vs SOC (HR: 1.04; 95% CI: 0.85–1.26; P = 0.76). Efficacy data are provided in the table. Treatment-related AEs Grade ≥3 were reported in 10.1% of pts (regardless of causality Grade ≥3 AEs were 41.4%) in the D arm, 16.3% (51.2%) for D+T, and 24.2% (44.2%) for SOC. Following treatment, 2% of pts in D, 5% in D+T and 15% in SOC received immunotherapy. Conclusions: D and D+T did not demonstrate a statistically significant improvement in OS compared to standard chemotherapy in pts with R/M HNSCC. Median OS and ORR of D arm were similar to other studies with checkpoint inhibitors. The SOC arm outperformed what has been seen for SOC arms in previous studies; subsequent immunotherapy may have confounded the OS analyses. The safety profile for D and D + T in R/M HNSCC is consistent with previous trials. Clinical trial information: NCT02369874. [Table: see text]

TPS8573 Background: Durvalumab, a selective, high-affinity, engineered human IgG1 mAb that blocks PD-L1 binding to PD-1 and CD80, is approved in the US, Japan and several other countries, for the treatment of patients (pts) with unresectable, stage III non-small cell lung cancer (NSCLC) whose disease has not progressed following concurrent chemoradiotherapy (cCRT). These approvals were based on results from the phase 3 PACIFIC study, in which durvalumab was given 1–42 days after completion of definitive cCRT and significantly improved progression-free survival (PFS) vs placebo (median 16.8 vs 5.6 months; HR 0.52, 95% CI 0.42– 0.65; p<0.001) and overall survival (OS) vs placebo (stratified HR 0.68; 99.73% CI 0.47–0.997; p=0.0025). Increasing evidence suggests additional benefit when anti-PD-1/PD-L1 therapies are administered alongside cCRT. The PACIFIC 2 study therefore aims to assess whether durvalumab plus cCRT provides additional benefit, in terms of PFS and objective response rate (ORR), compared with cCRT alone. Methods: PACIFIC 2 is a phase 3, randomized, double-blind, placebo-controlled, multicenter, international study. Approximately 300 pts with unresectable stage III NSCLC will be randomized (2:1) to receive either durvalumab (intravenous 1500 mg) every 4 weeks (q4w) + cCRT, or placebo q4w + cCRT. Eligible pts must have histologically or cytologically confirmed stage III disease; ECOG performance status 0 or 1; and life expectancy >12 weeks at randomization. Pts who discontinue treatment will be followed for safety and OS. Primary endpoints are PFS and ORR (RECIST v1.1) assessed via blinded independent central review. Secondary endpoints include OS; OS at month 24; complete response (CR) rate; duration of response; disease control rate; time to death/distant metastases; time from randomization to second progression; safety; and symptoms, functioning and global health status. Pts with a CR, partial response or stable disease will continue to receive durvalumab or placebo until clinical or RECIST v1.1-defined disease progression, or until another discontinuation criterion is met. Study enrollment began in March 2018 and recruitment is ongoing. Clinical trial information: NCT03519971.

TPS6589 Background: The PD-1 inhibitor pembrolizumab is currently approved as first-line monotherapy for patients with R/M HNSCC whose tumors express PD-L1 combined positive score (CPS) ≥1. In a phase 1b/2 trial (NCT02501096) of pembrolizumab plus lenvatinib (multikinase inhibitor of VEGFR 1-3, FGFR 1-4, PDGFRa, RET, and KIT) in solid tumors, the combination demonstrated promising antitumor activity and a manageable safety profile in patients with HNSCC. LEAP-010 (NCT04199104) is a randomized, double-blind, placebo-controlled, phase 3 study that will evaluate the efficacy and safety of first-line pembrolizumab with or without lenvatinib in patients with PD-L1–positive R/M HNSCC. Methods: Key eligibility criteria include histologically confirmed R/M HNSCC incurable by local therapies, PD-L1–positive tumor (CPS ≥1) as determined by central laboratory, measurable disease as assessed by blinded independent central review (BICR) per RECIST v1.1, and ECOG performance status (PS) 0 or 1. Patients will be randomly assigned 1:1 to pembrolizumab plus lenvatinib or pembrolizumab plus placebo. Randomization will be stratified by PD-L1 status defined by tumor proportion score ( < 50% vs ≥50%), human papillomavirus status for oropharynx cancer (positive vs negative), and ECOG PS (0 or 1). Patients will receive intravenous pembrolizumab 200 mg every 3 weeks for 35 cycles (~2 years) and oral lenvatinib 20 mg or placebo once daily; patients may continue to receive lenvatinib or placebo after pembrolizumab treatment is complete. Treatment will continue until BICR-verified disease progression or unacceptable toxicity. Pembrolizumab retreatment (second course) for 17 additional cycles will be allowed for eligible patients who stop pembrolizumab and subsequently experience BICR-verified disease progression. These patients could have stopped treatment with stable disease, partial response, or complete response or after 35 cycles of pembrolizumab for reasons other than disease progression or toxicity. Tumor imaging assessment will be performed at week 6, then every 6 weeks until 1 year, and thereafter every 9 weeks. Primary end points are objective response rate and progression-free survival, assessed by BICR per RECIST v1.1, and overall survival. Secondary end points are duration of response and safety and tolerability. Recruitment is ongoing; planned enrollment is ~500 patients. Clinical trial information: NCT04199104 .

TPS3618 Background: About 5% of mCRCs are dMMR, leading to high levels of MSI. CRCs with MSI-H have abundant lymphocyte infiltrates and strong expression of immune checkpoints. In the phase 2 KEYNOTE-016 study, the anti-programmed death 1 (PD-1) antibody pembro provided an ORR of 40% in patients (pts) with progressive dMMR mCRC vs 0% in pts with MMR-proficient mCRC. KEYNOTE-177 (ClinicalTrials.gov, NCT02563002) is an international, randomized, open-label, phase 3 study designed to evaluate the efficacy and safety of pembro vs standard-of-care (SOC) chemotherapy in the first-line setting for dMMR or MSI-H mCRC. Methods: Key eligibility criteria include age ≥ 18 years, locally confirmed dMMR or MSI-H stage IV CRC, measurable disease per RECIST v1.1 by local site assessment, ECOG performance status 0-1, no active autoimmune disease or brain metastases, and no prior therapy for mCRC. Pts are to be randomized 1:1 to receive either pembro 200 mg Q3W or investigator’s choice of SOC chemotherapy, which must be chosen prior to randomization; options include mFOLFOX6 or FOLFIRI alone or in combination with bevacizumab or cetuximab. Treatment is to continue until disease progression, unacceptable toxicity, pt/investigator decision, or completion of 35 cycles (pembro only). Response is to be evaluated Q9W per RECIST v1.1 by central imaging vendor review and per RECIST adapted for immunotherapy response patterns. Pts in the SOC arm who have disease progression and meet crossover criteria may be eligible to receive pembro for up to 17 treatment cycles. Eligible pts may continue pembro beyond initial RECIST-defined progression. AEs are to be assessed throughout treatment and for 30 days thereafter (90 days for serious AEs) and graded per NCI CTCAE v4.0. Pts are to be followed for survival Q9W. Primary end point is PFS per RECIST v1.1 by central imaging vendor review. Secondary end points include ORR per RECIST v1.1 by central imaging vendor review, OS, and safety and tolerability. Other end points include DOR and HRQoL. Planned enrollment in KEYNOTE-177 is 270 pts across 21 countries. Clinical trial information: NCT02563002.

We hypothesize that combination anti–PD-1 and anti-HER2 therapy will result in T-cell activation, augment ADCC, and potentiate antitumor immune response in HER2+ patients. This phase 2 study in HER2+ mG/GEJc demonstrated the safety and preliminary efficacy of trastuzumab/pembrolizumab/chemotherapy; the overall response rate was 87%, and the disease control rate was 100% Janjigian YY, ASCO GI 2019). KEYNOTE 811, a global, multicenter, randomized, placebo-controlled, phase 3 study, is underway. Methods: Key eligibility criteria are age ≥18 years; previously untreated unresectable or metastatic HER2+ (centrally confirmed IHC 3+ or IHC 2+/ISH >2.0) G/GEJ adenocarcinoma; life expectancy >6 months with RECIST v1.1 measurable disease; adequate organ function and performance status. Patients will be randomly assigned 1:1 to receive chemotherapy with pembrolizumab 200 mg IV flat dose or placebo with trastuzumab 6 mg/kg (after 8 mg/kg load) Q3W up to 2 years or until intolerable toxicity or disease progression. Investigator choice chemotherapy will include day 1 cisplatin 80 mg/m2 IV and /5-fluorouracil 800 mg/m2/day IV (days 1-5) or oxaliplatin 130 mg/m2 IV and capecitabine 1000 mg/m2 BID days 1-14 (Q3W). Primary end points are progression-free survival and overall survival. Secondary end points are objective response rate, duration of response, and safety and tolerability. Adverse events are graded per NCI CTCAE v4.0 and will be monitored for 30 or 90 days after treatment. Patients will be followed up for survival. Planned enrollment is approximately 692 patients. Clinical trial information: NCT03615326.

Potential Clinical Benefit

TPS601 Background: First-line systemic treatment options for advanced HCC pts are limited to the multi-targeted tyrosine kinase inhibitors, SORA and lenvatinib. Both agents improve outcomes for pts with advanced disease, but are associated with increased rate of grade ≥ 3 treatment-related adverse events. YIV-906 (PHY906, KD018) is derived from Huang-Qin-Tang, a traditional Chinese medicine documented 1800 years ago to treat gastrointestinal ailments. Preclinical data indicate YIV-906 increases inflammation in the tumor microenvironment by M1 macrophages activation/proliferation resulting in HCC tumor rejection in vivo and reduces SORA associated toxicity. Clinical experience with YIV-906 plus SORA suggests safety and potential clinical benefit to HCC pts with chronic HBV infection. Methods: This is a proof-of-concept, international, multicenter, double-blind, placebo-controlled, randomized phase 2 study designed to compare the efficacy of YIV-906 and SORA to SORA alone in advanced HCC pts (NCT04000737). Key eligibility criteria include age ≥ 18 years, HBV-associated HCC, ≥ 1 measurable untreated lesion, Child-Pugh A liver function, and no prior systemic therapy. An estimated 125 pts will be randomized 2:1 to receive the investigational (YIV-906 plus SORA) or control (placebo plus SORA) arm until disease progression or unacceptable toxicity. Pts will be stratified by metastatic status (extrahepatic/vascular invasion vs none) and ECOG performance status (0 vs. 1). The primary endpoint is progression-free survival (PFS). Secondary endpoints include objective response rate and disease control rate by mRECIST, time to progression, overall survival, quality of life, and safety by CTCAE version 4.0. Translational correlatives include pharmacokinetics, effects on oral/gut microbiota, and exploratory soluble biomarkers analysis. For the primary endpoint, sample size of 41 pts in control arm and 84 pts in the investigational arm achieves 90% power at a 0.05% significance level to detect a hazard ratio of 0.5 assuming the median PFS of the control SORA arm is 3.6 months and that of the combination arm is 7.3 months. Clinical trial information: NCT04000737.
