BackgroundHHIs, vismodegib and sonidegib, are approved for treatment of patients with mBCC or locally advanced BCC who are not candidates for surgery or radiation. There is no approved option for patients who progress on or are intolerant to HHIs. Cemiplimab is an anti-programmed cell death-1 monoclonal antibody approved for treatment of patients with metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not candidates for curative surgery or curative radiation. Here we present the prespecified interim analysis of the mBCC cohort from the pivotal Phase 2, non-randomized, multi-center study of cemiplimab in patients with advanced BCC who discontinued HHI therapy due to disease progression, intolerance, or no better than stable disease after 9 months (NCT03132636).MethodsPatients with mBCC (nodal and/or distant) received cemiplimab 350 mg intravenously every 3 weeks; interim analysis included patients with the opportunity to be followed for approximately 57 weeks. The primary endpoint was objective response rate (ORR) per independent central review (ICR). Secondary objectives included assessment of safety and tolerability, estimation of duration of response (DOR), progression-free survival (PFS), and overall survival (OS).ResultsIn this interim efficacy analysis of 28 patients, 82.1% were males and median age was 65.5 years (range 38−90). Six patients had a partial response, per ICR, for an ORR of 21.4% (95% CI, 8.3, 41.0). ORR per investigator assessment was 28.6% (95% CI, 13.2, 48.7). Among responders, observed DOR was 9−23 months. Median time to response per ICR was 3.2 months (range, 2.1−10.5). Median Kaplan–Meier (KM) estimation of PFS was 8.3 months. Median DOR had not been reached and median KM estimation of OS was 25.7 months. All six responses had observed durations of at least 8 months. The disease control rate was 67.9% (95% CI, 47.6, 84.1).The most common treatment emergent adverse events (TEAEs) regardless of attribution were fatigue (50.0%), diarrhea (35.7%), pruritus (25.0%), and constipation (25.0%). Hypertension (n=2) was the only Grade ≥3 TEAE regardless of attribution occurring in ≥2 patients. TEAEs leading to death occurred in one (3.6%) patient who died from staphylococcal pneumonia, considered unrelated to study treatment.ConclusionsThis interim analysis demonstrates that cemiplimab is the first agent to provide clinically meaningful anti-tumor activity, including durable responses, in patients with mBCC after progression or intolerance on HHI therapy.AcknowledgementsEditorial acknowledgment: Medical writing support was provided by Cindi Hoover, PhD of Prime, Knutsford, UK, funded by Regeneron Pharmaceuticals, Inc. and Sanofi.Ethics ApprovalThe study protocols and all amendments were approved by the institutional review board at each participating study site.

9511 Background: Mucosal melanoma is a rare malignant melanoma in Caucasians but ranks the second most common subtype in the Asian population. It is more often diagnosed at an advanced stage and responds poorly to current PD-1/PD-L1 inhibitors. Here we report the interim analysis results of ML41186, an open-label, multicenter, single-arm phase II study, aiming to evaluate the efficacy and safety of atezolizumab in combination with bevacizumab in patients (pts) with advanced mucosal melanoma. Methods: Eligible pts aged 18 to 75 years with histologically confirmed unresectable locally advanced or metastatic mucosal melanoma had at least one measurable lesion per RECIST version 1.1 at baseline, with an ECOG PS 0 or 1 and adequate hematologic and organ function. ML41186 is a Simon two-stage design study, if 22 pts completed ORR evaluation and more than 3 pts respond in stage I, the study then continue to Stage II. Atezolizumab and bevacizumab were administered at a fixed dose of 1200 mg and 7.5 mg/kg Q3W respectively (on day 1 of each 21-day cycle) until unacceptable toxicity or loss of clinical benefit. The primary endpoint is the objective response rate (ORR). The secondary endpoints include progression-free survival (PFS), duration of objective response (DoR), disease control rate (DCR), and safety. Results: By the cut-off date of 9th September 2020, 35 pts has been enrolled, among whom 22 pts in the stage I analysis set has completed two efficacy evaluation, while 28 pts (full analysis set) has completed at least one efficacy evaluation. In ITT populations (n=35), mean age was 58.9 years with 10 (28%) pts had ECOG PS of 1. LDH level elevated in 9 (25.7%) pts. More than half pts (19, 54.3%) had metastatic mucosal melanoma, of whom 3 (15.8%) pts had more than 3 metastasis sites and 4 (21.1%) pts had liver metastasis. In stage I analysis set (n=22), the best confirmed ORR was 36.4% (95% CI, 17.0%-59.3%). Median progression-free survival was 5.32 months (95% CI, 1.58-not reached), and the best confirmed DCR was 59.1% (95%CI, 36.4%-79.3%). The median confirmed DoR was not reached (95% CI, 2.76-NR). In the full analysis set (n=28), the unconfirmed ORR was 42.9% (95%CI, 24.5%-62.8%). In ITT populations (n=35), 28 pts (80%) experienced at least one adverse event (AE) and 5 pts (14.3%) experienced at least one grade 3-4 AEs. Only one patient experienced AE leading to treatment discontinuation. One patient died of autoimmune lung disease. Conclusions: The combination of atezolizumab plus bevacizumab showed promising benefit and was tolerable in pts with advanced mucosal melanoma. At the time of this interim analysis, the primary endpoint did not cross the futility boundary, thus the study will run into Stage II. Clinical trial information: NCT04091217.

Her2 Breast Cancer

1087 Background: Breast cancer is the most common cancer among women, with up to 37% of patients (pts) harboring germline BRCA1/2 mutations (g BRCA1/2m) that appear to be sensitive to poly (ADP-ribose) polymerase proteins 1 and 2 (PARP1/2) inhibition. Pamiparib is an orally administered selective PARP1/2 inhibitor that has the potential to cross the blood-brain barrier. This study evaluated the efficacy and safety of pamiparib in pts with locally advanced/metastatic human epidermal growth factor receptor 2-negative (HER2-) breast cancer, with deleterious or suspected deleterious g BRCA1/2m, who received ≤ 2 prior lines of chemotherapy. Methods: In this open-label, phase 2, multi-center study in China (NCT03575065), pts with locally advanced/metastatic HER2- breast cancer with deleterious or suspected deleterious g BRCA1/2m triple negative breast cancer (TNBC cohort) or hormone receptor-positive (HR+)/HER2- breast cancer (HR+ cohort) were enrolled. Pts received pamiparib 60 mg orally twice daily in 28-day cycles. The primary endpoint was objective response rate (ORR; RECIST v1.1) by independent review committee (IRC). Secondary endpoints included duration of response (DOR) and progression free survival (PFS) by IRC, overall survival (OS), safety and tolerability. Results: 88 pts were enrolled (median age 45.5 years), 76 pts (TNBC cohort n = 55; HR+ cohort n = 21) had measurable disease at baseline per IRC. 60 pts (68.2%) received 1 or 2 prior lines of chemotherapy; 42 pts (47.7%) were treated with platinum previously. Median follow-up was 13.77 months (TNBC cohort, 10.87 months; HR+ cohort, 18.45 months). In the TNBC cohort: confirmed ORR was 38.2% (95% CI: 25.4–52.3); median DOR (mDOR) was 6.97 months (95% CI: 3.94–not estimable[NE]); median PFS (mPFS) was 5.49 months (95% CI: 3.65–7.33); median OS (mOS) was 17.08 months (95% CI:13.70–NE). In the HR+ cohort: confirmed ORR was 61.9% (95% CI: 38.4–81.9); mDOR was 7.49 months (95% CI: 5.55–14.75); mPFS was 9.20 months (95% CI: 7.39–11.93); mOS was not reached (NR; 95% CI 18.10–NE). ≥ Grade 3 treatment emergent adverse events (TEAEs) occurred in 54 pts (61.4%); anemia was the most common TEAE, occurring in 77 pts (87.5%). Dose reduction due to TEAEs occurred for 57 pts (64.8%); discontinuations due to TEAEs occurred for 2 pts (2.3%). Conclusions: Pamiparib showed a promising response in pts with locally advanced/metastatic HER2- breast cancer with a g BRCA1/2m. The safety profile of pamiparib was considered acceptable and was generally consistent with therapies in the same class. Clinical trial information: NCT03575065 .[Table: see text]

TPS709 Background: Collecting ducts carcinoma (CDC) is a rare and aggressive form of renal cell carcinoma, characterized by extremely poor prognosis and resistance to agents effective in other forms of RCC. We hypothesized that cabozantinib, an inhibitor of multiple kinases including VEGFR 2, MET and AXL, may be superior in terms of efficacy to other angiogenesis inhibitors in the treatment of CDC due to its high-spectrum of activity against multiple and non-redundant oncogenic pathways. Methods: The BONSAI study is a prospective, single-centre, single-arm phase II trial evaluating cabozantinib in patients with untreated locally advanced or metastatic CDC. Cabozantinib will be administered at the dose of 60 mg orally once daily until the evidence of disease progression (PD) evaluated by RECIST 1.1 or unacceptable toxicity. Primary objective is the evaluation of objective response rate (ORR). Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety profile of cabozantinib. Exploratory objectives include the evaluation of genetic and immunological landscape of CDC and its correlation with response to treatment. Overall, 23 patients will be enrolled into the study based on a Simon’s two-stage optimal design. In order to reject an ORR equal to 15% with a one-sided alpha error of 10% and to detect an ORR equal to 35% with a power of 80%, 9 patients will be enrolled in the first stage. If at least 2 responses will be observed in the first stage, 14 additional patients will be included in the second stage. If at least 6 responses will be observed at the second stage the activity of cabozantinib will be proved. First patient enrollment is scheduled in November 2017.

6015 Background: Cemiplimab (REGN2810) produced substantial antitumor activity with durable responses in Phase 1 CSCC expansion cohorts and Phase 2 metastatic (m) CSCC cohort. We now present the primary analysis of the Phase 2 laCSCC cohort (NCT02760498; data cutoff date: Oct 10, 2018). Methods: Pts with laCSCC received cemiplimab 3 mg/kg IV every 2 weeks (Q2W). Tumor measurements were performed Q8W. The primary objective was to evaluate objective response rate (ORR; complete response [CR] + partial response [PR]) according to independent central review (per RECIST 1.1 for scans; modified WHO criteria for photos). Results: 78 pts were enrolled (59 M/ 19 F; median age: 74 years; ECOG PS: 0 in 38 pts, 1 in 40 pts; primary CSCC site: head/neck in 79.5%; prior systemic therapy: 15.4%; prior radiotherapy: 55.1%). Median duration of follow-up was 9.3 months (range: 0.8–27.9). ORR by central review was 43.6% (95% CI: 32.4–55.3; 10 CRs and 24 PRs); investigator-assessed (INV) ORR was 52.6% (95% CI: 40.9–64.0; 13 CRs and 28 PRs). Median duration of response (DOR) has not been reached. The longest DOR at data cut-off was 24.2 months and was still ongoing. Durable disease control rate (stable disease or response for ≥16 weeks) was 62.8% (95% CI: 51.1–73.5). Median observed time to response was 1.9 months (range: 1.8–8.8). Median progression-free and overall survival have not been reached. Tumor PD-L1 status is available for 48/78 pts, tumor mutational burden analysis (from targeted exome panel) is ongoing for ≥40/78 pts; response correlation analyses are planned. The most common treatment-emergent adverse events (AEs; all grades, Grade ≥3) were fatigue (42.3%, 1.3%), diarrhea and pruritus (both 26.9%, 0%), and nausea (21.8%, 0%). INV grade ≥3 immune-related AEs occurred in 10.3% of pts. One pt died due to an unknown cause that was assessed as treatment-related. Conclusions: Cemiplimab 3 mg/kg Q2W showed substantial antitumor activity, durable responses, and acceptable safety profile in pts with laCSCC. These data strongly support the recent FDA approval of cemiplimab-rwlc for pts with mCSCC or laCSCC who are not candidates for curative surgery or curative radiation. Clinical trial information: NCT02760498.

Abstract This randomized, open-label, multi-center phase 2 study (ClinicalTrials.gov, number NCT03116152) assessed sintilimab, a PD-1 inhibitor, versus chemo in patients with advanced esophageal squamous cell carcinoma (ESCC) refractory to first-line (1L) chemotherapy. The primary endpoint was overall survival (OS), while exploratory endpoint was the association of biomarkers with treatment efficacy. The median OS in the sintilimab group was significantly prolonged compared with that of the chemotherapy group, (objective response rates 12.6% and 6.3 %, respectively). Incidence of treatment-related adverse events of grade 3–5 was lower with sintilimab than with chemotherapy (20.2 vs. 39.1 %). Patients with high TCR clonality and low mTBI showed the longest median OS (15.0 mo), while patients with low NLR at 6 wk post-treatment had a significantly prolonged median OS compared with those with high NLR. High expression of T-follicular helper cells or activated B-cell signature was significantly associated with longer progression-free survival in the sintilimab group.

11551 Background: Based on the central role played by the vascular endothelial growth factor receptor (VEGFR) in immunosuppression, we assessed the activity and safety of VEGFR inhibitor pazopanib plus anti-PD-L1 blockade durvalumab in soft tissue sarcoma (STS). Methods: We did a single-arm, single-center, phase 2 study that enrolled patients with metastatic or locally advanced STS aged 19 years or older, ECOG PS 0-1, with at least one measurable lesion, and received at least one previous line of systemic therapy. Patient were given pazopanib 800 mg orally daily and durvalumab 1500 mg intravenously for 60 min every 3 weeks. The primary endpoint was investigator-assessed objective response. Results: Between September 2019 and October 2020, 47 participants were enrolled, of whom 46 (97.9%) were evaluable for the efficacy analyses. With a median follow up of 12.3 months, complete and partial response (PR) was achieved in 1 (2.2%) and 12 (26.1%) patients, resulting in 28.3 % of objective response rate. Median time to achieve PR was 1.4 months and median duration of response was 11.0 months. The most common treatment-related adverse events of any grade include fatigue (20 [42.6%]), anorexia (17 [36.2%]), diarrhea (17 [36.2%]), and AST elevation (16, [34.0%]). Thirty-one patients (67.3%) had progressive disease, and the median progression free survival was 8.6 months (95% CI 3.6-13.6). Conclusions: Durvalumab and pazopanib showed encouraging activity in patients with advanced STS. Molecular predictors with whole exome and RNA sequencing will be presented. Clinical trial information: NCT03798106.

Metastatic Urothelial Carcinoma

393 Background: Patients with locally advanced or metastatic urothelial carcinoma (la/mUC) have poor survival following progression after platinum-containing chemotherapy and PD-1/L1 inhibitor regimens. Enfortumab vedotin (EV) is an antibody-drug conjugate directed to Nectin-4, a cell adhesion molecule highly expressed in urothelial carcinoma, with remarkable efficacy observed in a single-arm trial in this setting. This randomized phase III study (EV-301) was performed to confirm these findings. Methods: EV-301 (NCT03474107) is a global, open-label phase III study of EV vs chemotherapy conducted in patients with la/mUC who had received a prior platinum-containing chemotherapy and had disease progression during or after PD-1/L1 inhibitor treatment. Patients were randomized 1:1 to receive EV (1.25 mg/kg) on Days 1, 8, and 15 of each 28-day cycle or investigator choice of standard docetaxel, paclitaxel, or vinflunine chemotherapy. The primary endpoint was overall survival (OS); secondary endpoints included investigator-assessed progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) per RECIST v1.1, as well as safety/tolerability. A prespecified interim analysis, which tested OS at an adjusted 1-sided significance level of P = 0.00679, was performed when ≥285 deaths had occurred. The results of this interim analysis are presented here. Results: Overall, 608 patients with la/mUC were randomly assigned to EV (n=301) or chemotherapy (n=307). As of July 15, 2020, 301 deaths had occurred (EV, n=134; chemotherapy, n=167). After an 11.1 mo follow-up, median OS was significantly prolonged by 3.9 mo with EV compared with chemotherapy (median OS: 12.9 vs 9.0 mo, respectively; HR=0.70 [95% CI: 0.56-0.89], 1-sided P =0.001). Additionally, the OS benefit of EV was retained in the majority of prespecified subgroups. Progression-free survival also was improved with EV (5.6 mo) vs chemotherapy (3.7 mo) (HR=0.61 [95% CI: 0.50-0.75]; 1-sided P <0.00001). Both ORR and DCR were significantly higher with EV vs chemotherapy (40.6% vs 17.9% and 71.9% vs 53.4%, respectively; 1-sided P <0.001 each). Rates of treatment-related adverse events (TRAEs; 93.9% vs 91.8%), including serious TRAEs (22.6% vs 23.4%), were comparable between the EV and chemotherapy groups. Rates of grade ≥3 TRAEs were ~50% in both groups; decreased neutrophil count (13.4%) and white blood cell count (6.9%) were more common in the chemotherapy group, and maculo-papular rash (7.4%) was more common in the EV group. Conclusions: EV is the first therapy to show significant survival advantage over standard chemotherapy in patients with treatment-experienced la/mUC. With robust clinical benefit and a tolerable safety profile, EV is a new standard of care for this aggressive disease. Clinical trial information: NCT03474107.

TPS2662 Background: IRX-2 is a biologic immunotherapeutic containing a mixture of cytokines including IL-2, IL-1β IL-6, IL-8, TNFα, GM-CSF, and IFN-γ. It is derived from stimulating human PBMCs with phytohemagglutinin. Preclinical studies have shown that IRX-2 enhances dendritic cell maturation, T cell activation, and NK cell stimulation. In a Phase 2 trial of head and neck squamous cell carcinoma (HNSCC) patients, IRX-2 increased immune activation in the tumor microenvironment and was correlated with greater progression free survival and overall survival. Moreover, it has been shown that the degree of lymphocyte infiltration is an important prognostic factor for treatment with anti- programmed cell death protein 1 (PD-1) monoclonal antibodies. These data provide a compelling rationale for incorporating IRX-2 regimen into anti-PD-1 treatment strategies to increase the level of lymphocyte infiltration in the TME and improve immune response. Methods: This is a phase Ib trial exploring safety and tolerability of IRX-2 regimen in combination with nivolumab. Patients with recurrent or metastatic renal cell carcinoma, urothelial carcinoma, non-small cell lung cancer, HNSCC and melanoma are eligible. Patients who have received prior anti-PD-1/PD-L1 antibodies are eligible. IRX-2 regimen consists of cyclophosphamide 300mg/m2 (Day 1) and subcutaneous IRX-2 injections in 2 or 4 lymph node-bearing regions (based on dose level) for 10 days every 3 months. Two dose levels of IRX-2 regimen will be studied. Nivolumab is administered at 240 mg Q2W. Once the RP2D is determined, an additional 88 pts will be enrolled in an expansion phase, for a planned total enrollment of approximately 100 pts. Dose expansion phase will include cohorts of the 5 different diseases. Each cohort will include two groups: 1) anti-PD-1/PD-L1 antibody naïve tumors, and 2) progressed during or after anti-PD-1/PD-L1 antibodies. The primary study objective is to determine safety and tolerability of combination therapy. Secondary objectives are to evaluate the objective response rate, progression-free survival, and overall survival. Study Progress: Study is actively accruing. Clinical trial information: NCT03758781.

Targeted agents form the backbone of most therapeutic strategies in advanced renal cell carcinoma (aRCC) but ultimately resistance develops, and toxicity often leads to discontinuation of treatment, limiting the clinical benefits of these treatments. Nivolumab, a fully human IgG4 anti-PD-1 antibody, selectively blocks the interaction between PD-1 and its ligands PD-L1 and PD-L2 and provides a novel therapy option for patients with aRCC. In 2015, the pivotal phase III study CheckMate 025 led to the Food and Drug Administration approval of nivolumab in patients with aRCC who had received prior anti-angiogenic therapy, and in 2017, the phase III study CheckMate 214 showed that combined immunotherapy with nivolumab plus ipilimumab resulted in greater objective response rate and prolonged progression-free survival when compared with sunitinib in intermediate- and poor-risk patients with previously untreated aRCC. Early studies of nivolumab in association with anti-angiogenic therapy have generated enthusiasm and multiple combination trials are ongoing.

However, as with crizotinib, resistance to alectinib and ceritinib eventually develops, with secondary resistance mutations detected in approximately 50% of pts. Brigatinib is a next-generation ALK TKI designed to have potent and broad activity against ALK mutants. Post-crizotinib, brigatinib demonstrated high systemic and CNS objective response rates (ORR) and the longest reported median progression-free survival (PFS) of any ALK inhibitor in this setting (16.3–16.7 mo) (Huber. J Clin Oncol 2018;36; Bazhenova. Ann Oncol 2017;28); efficacy was demonstrated regardless of mutations. Based on nonclinical and clinical data, brigatinib may show efficacy in ALK+ NSCLC that has developed resistance or failed to respond to alectinib/ceritinib. This trial was designed to assess efficacy and safety of brigatinib in pts with ALK+ NSCLC that has progressed on alectinib or ceritinib. Methods: This is a phase 2, open-label, single-arm, multicenter, international trial (NCT03535740) in pts (≥18 y) with locally advanced/metastatic NSCLC and disease progression on alectinib or ceritinib (± prior crizotinib; ≤3 different systemic regimens for locally advanced/metastatic disease). Pts receive oral brigatinib 180 mg QD with 7-day lead-in at 90 mg QD. Treatment beyond progression or escalation to brigatinib 240 mg QD is permitted. Primary endpoint: independent review committee (IRC)−assessed confirmed ORR (cORR) per RECIST v1.1. Secondary endpoints: investigator (INV)-assessed cORR, duration of response (INV- and IRC-assessed), PFS, disease control rate, and time to response; in pts with baseline brain metastases: IRC-assessed intracranial cORR, duration of intracranial response, and intracranial PFS; OS; safety/tolerability; and HRQoL. Exploratory endpoints include biomarker analyses. The study was initiated in Dec 2018 at 78 sites (North America, Europe, Asia), with a planned sample size of 103 pts. Accrual is ongoing. Clinical trial information: NCT03535740.
