BackgroundRetifanlimab (INCMGA00012) is a humanized, hinge-stabilized immunoglobulin G4 kappa (IgG4κ), anti-programmed cell death protein (PD)-1 monoclonal antibody with safety and clinical pharmacology that are characteristic for the class. Evaluation of retifanlimab in solid tumors is under investigation in phase 2 and 3 studies. POD1UM-201 is an open-label, single-arm, multicenter, phase 2 study evaluating the efficacy and safety of retifanlimab in patients with chemotherapy-naïve or chemotherapy-refractory advanced/metastatic Merkel cell carcinoma (MCC). Updated results from the chemotherapy-naïve cohort are reported here.MethodsEligible patients were ≥18 years of age, had metastatic or recurrent unresectable loco-regional MCC, Eastern Cooperative Oncology Group performance status ≤1, measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, and had not received prior systemic treatment for MCC. Retifanlimab 500 mg IV every 4 weeks (Q4W) was administered for up to 2 years. The primary endpoint was overall response rate (ORR) assessed by independent central review per RECIST v1.1. Secondary endpoints included duration of response, disease control rate (DCR; defined as proportion of patients with either an objective response or stable disease lasting at least 6 months), progression-free survival, overall survival, safety, and pharmacokinetics.ResultsAs of April 16, 2021, 87 patients with chemotherapy-naïve advanced/metastatic MCC had received retifanlimab. Per protocol, the primary efficacy analyses are based on the first 65 patients assessed. At the data cutoff, 34 of these 65 patients (52.3%) were on treatment; 4 (6.2%) had completed treatment; and 27 (41.5%) had discontinued treatment for reasons including disease progression (18 [27.7%]), adverse event (AE; 7 [10.8%]), death (1 [1.5%]), and physician decision (1 [1.5%]). The ORR in these patients was 46.2% (n=30: complete response, 8 [12.3%]; partial response, 22 [33.8%]). The DCR was 53.8% (n=35). Other secondary efficacy results are not yet mature. Among all treated patients (n=87), 66 (75.9%) had a treatment-emergent AE (TEAE), 25 (28.7%) had a grade ≥3 TEAE, and 12 (13.8%) had a grade ≥3 treatment-related AE. Twenty-three patients (26.4%) had an immune-related AE (irAE), and 8 (9.2%) had a grade ≥3 irAE. Four patients (4.6%) discontinued treatment due to irAEs (peripheral sensorimotor neuropathy, pancreatitis, eosinophilic fasciitis, and polyarthritis [each n=1]). One patient (1.1%) had a grade 3 infusion reaction.ConclusionsThese data from the POD1UM-201 trial show that retifanlimab monotherapy at 500 mg Q4W continues to demonstrate promising clinical activity and safety in patients with advanced/metastatic chemotherapy-naïve MCC. Updated results will be presented at the meeting.AcknowledgementsThe study is sponsored by Incyte Corporation (Wilmington, DE). Statistical support was provided by Xiaohan Xu of Incyte Corporation.

BackgroundCFI-402411 is an orally available small molecule potent inhibitor of HPK1 (Hematopoietic progenitor kinase 1). T-cells are negatively-regulated at different junctures of cancer-immunity cycle by this regulatory kinase. HPK1, (also mitogen activated protein kinase kinase kinase kinase 1 (MAP4K1)) is a protein serine/threonine kinase predominantly expressed in hematopoietic cells. In T-cells, following T-cell receptor activation, HPK1 is recruited to the plasma membrane where it phosphorylates the adapter protein SH2 domain-containing leukocyte protein of 76 kDa (SLP-76), down-regulating signaling events required for T cell activation and proliferation. Selected for development based on its pharmacologic properties and preclinical activity in a variety of syngeneic cancer models and assays, with an IC50 = 4.0±1.3 nM, CFI-402411 is expected to relieve HPK1-mediated inhibition of T and B cells, facilitating an anti-tumor immune response.MethodsPhase 1, 3 + 3 design in patients. Patients have acceptable laboratory, other parameters for study entry. Single agent dose daily oral escalation cohort (A1) in advanced tumors, then dose expansion (A3) with biomarker backfill (A2) in select advanced tumors; combination with PD-1 Inhibitor (pembrolizumab) (B1, pembrolizumab eligible tumors with no prior grade >=3 related to CPI)) and expansion (B2, PD-1/PD-L1 naïve pembrolizumab eligible tumors). DLT defined as any grade >=3 toxicity in first cycle of therapy (21d cycles). Standard assessments for response per RECIST v1.1 or iRECIST. The starting dose level was 80mg.ResultsAt 10 June 2021 data is available for 12 patients from A1. Median age 61.5 years (range 33–73), 8 patients female, and 10 white. Diagnoses were pancreatic cancer, colorectal (3 pts), ovarian, basal cell, cholangiocarcinoma, sigmoid, salivary and breast cancer (1 pt). Six patients (50%) had 4 prior therapies, 1 patient (basal cell) had prior treatment with immune checkpoint inhibitor, pembrolizumab. Four doses studied: 80, 120, 180 and 270mg. TEAEs across all CTCAE grades, (in >2 patients) were diarrhea (6 patients), nausea (4 patients), dyspepsia (3 patients), fatigue (3 patients). No related grade 3–5 events, one immune related event (grade 1, weight loss). 3 grade 3 events all unrelated to study drug - pleural effusion, rash, thromboembolic event. Discontinuation due to disease progression was main reason (7 patients). PK and PD assessments will be updated at time of presentation.ConclusionsCFI-402411 is a potent inhibitor of HPK1 that is well tolerated with a manageable adverse event profile and dose escalations continue. Further safety and efficacy results will be presented at the meeting including additional cohorts if available.AcknowledgementsTreadwell Therapeutics thanks all sites, importantly their patients and their families.Trial RegistrationClinicalTrials.gov Identifier: NCT04521413Ethics ApprovalThis study obtained has obtained ethics approvals at multiple institutions globally including;USAWCG IRB - Western Institutional Review Board - MOD00002618 (Submission ID)IntegReview Institutional Review Board - N/AAdvarra Central IRB - SSU00130103IntegReview Institutional Review Board N/AAdvarra Central IRB - SSU00137751Advarra Central IRB - SSU00143275The University of Texas MD Anderson Cancer Center Institutional Review Board - 2020–0678 (IRB ID Number)Hong KongJoint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee - 2020.367 (Ref Number)CanadaOntario Cancer Research Ethics Board - 3320 (Project ID)Health Research Ethics Board of Alberta, HREBA Cancer Committee - HREBA.CC-20–0504 (Ethics ID Number)South KoreaimCORE - Seoul National University Hospital Institutional Review Board - H-2012-094-1182 (IRB Number)National Cancer Institute Review Board - 2020–0525–0001 (Receipt Number)All participants gave informed consent before taking part in this clinical trial.

4028 Background: Despite multidisciplinary therapies, prognosis of pts with resectable esophageal squamous cell carcinoma (ESCC) remains poor. Combining PD-1 blockade to neoadjuvant chemotherapy might be a feasible and effective strategy. Camrelizumab (an anti-PD-1 antibody) was approved for advanced or metastatic ESCC in the second-line setting and showed improved anti-tumor activity and survival benefit when combined with chemotherapy in multiple advanced tumors. Methods: In this NIC-ESCC2019 phase 2 study, histologically or cytologically confirmed ESCC pts (stage II-IVA) were enrolled to receive two cycles of neoadjuvant chemoimmunotherapy (NIC) with camrelizumab (200 mg on day 1) plus nab-paclitaxel (260 mg/m² in total on day 1 and day 8) and cisplatin (75 mg/m² in total on days 1-3) of each 21-day cycle, followed by esophagectomy. The primary endpoint was complete pathologic response (CPR) rate in the primary tumor. Besides, we also explored the relationship between the tumor genomic profile or primary-tumor microenvironment and the pathological response. Results: Between Jan 17, 2020 and Dec 8, 2020, 56 pts were enrolled. 51 pts underwent surgical resection, and all had complete tumor resection. CPR was achieved in 18 (35.3%; 95% CI, 21.7%-48.9%) pts; 12 (23.5%) pts had major pathologic response (MPR), and 21 (41.2%) had incomplete pathological response (IPR). Of note, 16 (31.4%) pts achieved CPR in both primary tumor and lymph nodes. The objective response rate was 66.7% (95% CI, 40.0-70.4). No in-hospital mortality occurred. The most common treatment-related adverse events (TRAEs) were decreased WBC (20 [36%] of 56 pts), vomiting (19 [34%]), and alopecia (18 [32%]). Grade 3 TRAEs only occurred in 6 (11%) pts, and there were no grade 4 or 5 TRAEs. The most common immune-related AEs included grade 1-2 rash maculo-papular (7 [13%]) and reactive cutaneous capillary endothelial proliferation (5 [9%]). Presence of mutations in CREBBP and KMT2D at treatment-naïve time-point was correlated with non-response group (IPR and stable disease) (CREBBP, p = 0.046; KMT2D, p = 0.047). Among the immune populations, CD8+, CD8+PD-1+ and CD8+PD-L1+ T cells increased significantly after two doses of NIC, especially in the CPR+MPR group (CD8+, p = 0.013; CD8+PD-1+, p < 0.001; CD8+PD-L1+, p = 0.068). Conclusions: The addition of camrelizumab to neoadjuvant chemotherapy in ESCC demonstrated promising efficacy with acceptable toxicity, supporting the further investigation in a randomized phase 3 clinical trial.

BackgroundMerkel cell carcinoma (MCC) is a rare and aggressive skin cancer with neuroendocrine features, and it is associated with elevated mortality. The pathogenesis is associated with presence of clonally integrated Merkel cell polyomavirus (MCPyV) or ultraviolet light (UV) exposure.1 The MCPyV causes up to 80% of MCC tumors in North America and Europe.2–4 Recently immunotherapy is having good results,5 the phase 2 trial JAVELIN Merkel 200 indicated that treatment with Avelumab (PDL1 inhibitor) in patients with metastatic MCC pre-treated have a meaningful long-term survival outcomes respect chemotherapy. Moreover, ORRs were highest in patients with high TMB that were also MCPyV−, PD-L1+ or had a greater CD8+ T cell density at the invasive margin.6 In this study, we investigated the biological signatures in patients with MCPyV or not.MethodsFrom April 2011 to June 2018, we collected retrospectively 50 FFPE (Formalin-Fixed Paraffin-Embed) from 37 patients with metastatic MCC and 13 tissues from a secondary metastatic site. All patients have appropriately signed informed consent. We performed an immunohistochemistry assays (IHC) for MCPyV and PDL1. In addition, through the NanoString GeoMx DSP (Digital Spatial Profiling), we analysed 11 patients (6 MCPyV+; 5 MCPyV-) with cutaneous metastasis using a 44-plex antibody cocktail. For each slide we selected three different areas: Intratumoral, extratumoral and tumour border, in each area we selected CD4+ and CD8+ cells in 4 different ROIs (Region of Interest). Statistical analysis was performed via Bonferroni correction, P< 0.05 was considered statistically significant for median stratification.ResultsThe DSP analysis showed that the tumour border cells have an overexpression of IDO respect intratumoral area (adj. p<0.01). Instead, extratumoral area of MCPyV- patients have a higher expression of B7-H3 respect MCPyV+ as well as FOXP3 is higher in the tumour border of MCPyV+ patients and EpCAM in the intratumoral area (p<0.05). PDL1 is overexpressed in MCPyV+ CD4+ cells respect CD8+ (p<0.05). The IHC assay shown that viral status does not change in multiple metastases and PDL1 is elevated in the tumour border (p<0.05).ConclusionsIn this retrospective study, our preliminary data shown that tumour edge have an important role in the modulations of immune infiltrate and patients with Merkel cell polyomavirus could have a different pathway of immunosuppression compared to patients with non-virus related etiology. Further investigations are needed to get additional information.AcknowledgementsThe study was supported by the Institutional Project ”Ricerca Corrente” of Istituto Nazionale Tumori IRCCS Fondazione ”G.

Background Pomalidomide is an immunomodulatory drug that has been approved for the treatment of relapse refractory myeloma. A previous small randomized phase 2 study in the United States showed that combination of Pomalidomide, cyclophosphamide and dexamethasone induce a greater response rate than pomalidomide and dexamethasone1. In our prior study, AMN0012, we should that in patients with sub-optimal response to pomalidomide and dexamethasone, the addition of cyclophosphamide can increase response resulting in improvement of progression free survival. In the current study, we seek to randomize Asian patients with RRMM between PCD and PD to confirm the benefit of PCD. Method We conducted a prospective randomized trial of pomalidomide (4mg daily for 21 days followed by 7 days rest) plus dexamethasone 40mg once weekly for 4 weeks with or without cyclophosphamide (400mg once a week) in patients with relapse and refractory myeloma that has to be refractory to lenalidomide and has prior exposure to proteasome inhibitors. Each cycle is 4 weeks. Patients from Singapore, Japan and Korea (NCT03143049) were included in this Asian Myeloma Network trial. The trial was started in Sep 2017 and is still ongoing. To date, 53 patients have been recruited so far. This interim report presents data available up till the data cut-off date of 24 June 2020. Results Forty-six patients have available base line information and safety data and is included in this interim analysis. 50% of patients are male and median age of the cohort is 68 years old. 39% and 28% of patients are International Stage System (ISS) stage 2 and 3 respectively. 20% of patients have abnormal creatinine clearance. Median prior line of treatment is 3. All patients are refractory to lenalidomide and 96% have prior exposure to bortezomib. In addition, 12 patients (26%) and 5 (11%) have been treated with Carfilzomib and Ixazomib respectively. 15 (33%) patients had prior high dose melphalan and autologous stem cell transplant. 20 (44%) patients required dose reduction of pomalidomide, cyclophosphamide or dexamethasone. 89% of patients experience adverse events (AEs) of any grade. Of the 297 episodes of AEs, 43% are grade 3 or higher, with 50% of these episodes related to the study drugs. 57% of patients experienced serious AEs (SAEs) of any grade. Of the 74 episodes of SAE, 89% are grade 3 or higher, with 49% of these episodes related to the study drugs. Almost all of these events are related to cytopenias and infections. 20 (44%) of the patients develop grade 3 neutropenic fever and 9 (20%) patients have grade 3 or higher pneumonia. Only 1 patient experienced grade 3 peripheral neuropathy, 1 patient develop grade 3 pulmonary embolism, 1 patient developed grade 3 venous thromboembolism, and 1 patient experienced grade 3 renal impairment. At a median follow-up of 10.9 months, 9 of the 46 patients have died, and 21 have progressed. Three patients withdrew due to toxicity. While the overall response of the study population is not part of this interim analysis, we assessed the response of patients from the National University Cancer Institute, Singapore which has the highest number of patients recruited to get an idea of the therapeutic efficacy. Of the 14 patients recruited at NCIS, 1 patient achieved CR, 3 VGPR, 7 PR, producing a response rate of 79%. Conclusion In this interim analysis of a prospective randomized study of pomalidomide and dexamethasone with or without cyclophosphamide in Asian patients, we demonstrated the feasibility and efficacy of this combination. Longer follow-up and final analysis of the study will be needed to ascertain the therapeutic advantage of PCD over PD in relapse and refractory myeloma that is refractory to lenalidomide.

Abstract Idiopathic multicentric Castleman disease (iMCD) is a rare lymphoproliferative disorder. The anti–interleukin 6 (IL-6) therapy siltuximab is not available everywhere, and is not effective for over one-half of patients. Alternative treatment approaches are urgently needed. In the first iMCD clinical trial directed against a target other than IL-6 signaling, we investigated a thalidomide-cyclophosphamide-prednisone (TCP) regimen in newly diagnosed iMCD patients. This single-center, single-arm, phase 2 study enrolled 25 newly diagnosed iMCD patients between June 2015 and June 2018. The TCP regimen (thalidomide 100 mg daily for 2 years; oral cyclophosphamide 300 mg/m2 weekly for 1 year; prednisone 1 mg/kg twice a week for 1 year) was administered for 2 years or until treatment failure. The primary end point was durable tumor and symptomatic response for at least 24 weeks. Twelve patients (48%) achieved the primary end point with no relapse, 3 patients (12%) demonstrated stable disease, and 10 patients (40%) were evaluated as treatment failure. Even when considering all patients, there were significant (P &lt; .05) improvements in median symptom score, IL-6 level, hemoglobin, erythrocyte sedimentation rate, albumin, and immunoglobulin G. Among responders, the median levels of all evaluated parameters significantly improved, to the normal range, after treatment. The regimen was well tolerated. One patient died of pulmonary infection and 1 patient had a grade 3 adverse event (rash); 2 patients died following disease progression. Estimated 1-year progression-free survival and overall survival were 60% and 88%, respectively. The TCP regimen is an effective and safe treatment of newly diagnosed iMCD patients, particularly when siltuximab is unavailable. This trial was registered at www.clinicaltrials.gov as #NCT03043105.
