Description: CD20-TCB (RG6026) is a novel T-cell-engaging bispecific (TCB) antibody with a '2:1' molecular format that comprises two fragment antigen binding regions that bind CD20 (on the surface of B cells) and one that binds CD3 (on the surface of T cells). CD20-TCB offers the potential for increased tumor antigen avidity, rapid T-cell activation, and enhanced tumor cell killing versus other bispecific formats. CD20-TCB has demonstrated highly promising single-agent activity in relapsed or refractory (R/R) B-cell non-Hodgkin lymphoma (B-NHL) patients (pts) (Dickinson et al. ICML 2019). Preclinical data demonstrate CD20-TCB-induced programmed cell death protein 1 (PD-1) and programmed cell death-ligand-1 (PD-L1) upregulation on T cells and tumor cells. We hypothesized that the combination of T-cell engagement by CD20-TCB and PD-L1 inhibition by atezolizumab could lead to additive anti-tumor activity in B-NHL. We report preliminary data from NP39488 (NCT03533283), an ongoing Phase Ib study evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy (objective response rate [ORR] and complete response [CR] rate per modified Lugano 2014 criteria) of CD20-TCB in combination with atezolizumab in R/R B-NHL pts. A single dose of 1000mg obinutuzumab (G) is administered on Day −7 of Cycle 1 as pretreatment (Gpt) to mitigate for potential cytokine release syndrome (CRS). CD20-TCB is initiated on Day 1 of Cycle 1 and given in a q3w schedule. From Cycle 2 onwards, atezolizumab (1200mg) is added and given on the same day as CD20-TCB. CD20-TCB dose-escalation is ongoing and is guided by the modified continual reassessment method-escalation with overdose control (mCRM-EWOC). As of June 25, 2019, 38 pts with aggressive B-NHL (n=33; diffuse large B-cell lymphoma [DLBCL], transformed [tr] follicular lymphoma [FL], primary mediastinal large B-cell lymphoma, mantle cell lymphoma, tr lymphoplasmacytic lymphoma, tr Waldenstrom`s macroglobulinemia) or indolent B-NHL (n=5; FL) had received CD20-TCB doses from 0.07mg to currently 6mg. Pts (52.6% male) had a median age of 67 years (range: 38-82) and a median of three prior treatment lines (range: 1−10); 84% had refractory B-NHL. Two dose-limiting toxicities (Grade [Gr] 3 tumor flare at 6mg during Cycle 1 and Gr 3 myopathy at 1.8mg during Cycle 2) were transient and resolved completely. The most frequent adverse event (AE) was CRS (42%; 16/38 pts), with 24% Gr 1 (n=9), 18% Gr 2 (n=7), and no Gr ≥3 (according to Lee criteria, Lee et al. Blood 2014;124:188-95). The most common AEs (〉20%) were pyrexia (37%), anemia (29%), fatigue (24%), neutropenia (21%), diarrhea (21%), and decreased appetite (21%). The most common Gr ≥3 AEs (〉10%) were neutropenia (18%) and anemia (13%), with a single Gr 5 unrelated pneumonia. Three pts experienced a transient Gr ≥3 neurotoxicity (Gr 4 polyneuropathy, Gr 3 trigeminal nerve herpes zoster infection, and Gr 3 post-infection encephalopathy), all of which resolved. Thirty-six pts reached their first response assessment or withdrew early and were eligible for efficacy analysis. Across all doses, ORR and CR rates by investigator assessment were 36% (13/36 pts) and 17% (6/36), respectively (indolent NHL: 4/5 and 3/5 pts; aggressive NHL: 9/31 and 3/31 pts). All CRs are ongoing at the time of abstract submission. CD20-TCB exposure and receptor occupancy (RO%) increased dose-dependently across the dose-range evaluated, and are expected to be further optimized (Djebli et al. ASH 2019). At the higher CD20-TCB doses investigated, a trend towards increased clinical activity was observed (ORR of 60% [9/15 pts] in the 4mg and 6mg cohorts combined). The combination of CD20-TCB and atezolizumab has manageable safety in R/R B-NHL pts. No new safety signals or signs of increased immune-related AEs were detected, and the overall safety profile was consistent with that reported with single-agent CD20-TCB (Dickinson et al. ICML 2019). Dose escalation is ongoing and aims to optimize the dose and schedule of CD20-TCB when combined with atezolizumab using the established exposure-response model for CD20-TCB (Djebli et al. ASH 2019). Updated safety, efficacy, and biomarker data will be presented.

OffLabel Disclosure: CD20-TCB (also known as RG6026, RO7082859) is a full-length, fully humanized, immunoglobulin G1 (IgG1), T-cell-engaging bispecific antibody with two fragment antigen binding (Fab) regions that bind to CD20 (on the surface of B cells) and one that binds to CD3 (on the surface of T cells) (2:1 format). The 2:1 molecular format of CD20-TCB, which incorporates bivalent binding to CD20 on B cells and monovalent binding to CD3 on T cells, redirects endogenous non-specific T cells to engage and eliminate malignant B cells. CD20-TCB is an investigational agent.

Description: The severity of coronavirus disease 2019 (COVID-19) varies significantly with cases spanning from asymptomatic to lethal with a subset of individuals developing Severe Acute Respiratory Syndrome (SARS) and death from respiratory failure. To determine whether global nucleosome and citrullinated nucleosome levels were elevated in COVID-19 patients, we tested two independent cohorts of COVID-19 positive patients with quantitative nucleosome immunoassays and found that nucleosomes were highly elevated in plasma of COVID-19 patients with a severe course of the disease relative to healthy controls and that both histone 3.1 variant and citrullinated nucleosomes increase with disease severity. Elevated citrullination of circulating nucleosomes is indicative of neutrophil extracellular trap formation, neutrophil activation and NETosis in severely affected individuals. Importantly, using hospital setting (outpatient, inpatient or ICU) as a proxy for disease severity, nucleosome levels increased with disease severity and may serve as a guiding biomarker for treatment. Owing to the limited availability of mechanical ventilators and extracorporal membrane oxygenation (ECMO) equipment, there is an urgent need for effective tools to rapidly assess disease severity and guide treatment selection. Based on our studies of two independent cohorts of COVID-19 patients from Belgium and Germany, we suggest further investigation of circulating nucleosomes and citrullination as biomarkers for clinical triage, treatment allocation and clinical drug discovery.

Description: Background: Up to 50% of patients suffering from Non-Hodgkin`s lymphoma (NHL) become refractory to or relapse after treatment (M. Crump, Blood 2017). With this, the lack of curative outcomes for patients with both indolent and aggressive NHL subtypes remains an unmet medical need. The CD20 CD3 T cell bispecific antibody glofitamab induces specific T-cell activation and has demonstrated significant single agent activity in r/r NHL patients (NP30179 study, M. Dickinson, EHA 2020, Abstract S241). RO7227166, a CD19 targeted 4-1BBL (CD137) costimulatory agonist has shown synergistic anti-tumor activity when combined with glofitamab in preclinical models (fig 1). RO7227166 is a bispecific antibody-like fusion protein composed of a split trimeric 4-1BB ligand, a tumor antigen-targeting moiety recognizing CD19, and a silent Fc part preventing Fc-mediated toxicity. 4-1BB is an inducible co-stimulatory molecule expressed by activated T-cells or NK cells. Through CD19-binding, the 4-1BB ligand moiety can deliver co-stimulatory signals to activated T- and NK-cell subsets in the tumor. The expected mode of action (MoA) for this molecule is to deliver a costimulatory signal 2 to enhance the effector function of tumor-infiltrating T cells or NK cells upon their activation (signal 1) by a T-cell bispecific antibody (e.g. glofitamab, RO7082859) or a tumor-targeted ADCC antibody (e.g. obinutuzumab). By delivering direct T-cell-target cell engagement followed by costimulatory activation the aim is to offer a highly active off-the-shelf immunotherapy combination. Methods: RO7227166 is being developed in combination with glofitamab and obinutuzumab in a phase I, open-label, dose-escalation study BP41072 (NCT04077723). The study is designed to evaluate the combination maximum tolerated dose (MTD), safety, tolerability, pharmacokinetic (PK), and/or pharmacodynamic (PD) profile of escalating doses of RO7227166, and to evaluate preliminary anti-tumor activity in participants with r/r NHL. The dose escalation stage is divided into Part I (combination with obinutuzumab) and Part II (combination with glofitamab) followed by an expansion stage (Part III). During Part I patients receive 1000mg obinutuzumab intravenously (IV) at a q3w schedule in combination with CD19 4-1BBL IV. During part II glofitamab is given in a q3w schedule with RO7227166 introduced at C2D8 and administered concomitantly from C3D1 onwards. A fixed dose of obinutuzumab (Gpt; pre-treatment) is administered seven days prior to the first administration of RO7227166 and seven days prior to the first administration of glofitamab (M. Bacac, Clin Cancer Res 2018; M. Dickinson, EHA 2020, Abstract S241). Patients will initially be recruited into part I of the study only using single-participant cohorts, where a rule-based dose-escalation is implemented, with dosing initiated at 5 μg (flat dose). As doses of RO7227166 increase, multiple participant cohorts will be recruited and dose-escalation will be guided by the mCRM-EWOC design for overdose control. Commencement of Part II including decision on the RO7227166 starting dose will be guided by safety and PK data from Part I. Patients with r/r NHL meeting standard organ function criteria and with adequate blood counts will be eligible. The maximum duration of the study for each participant will be up to 24 months in Part I (excluding survival follow-up) and up to 18 months in Part II and Part III. Tumor biopsies and peripheral blood biomarker analyses will be used to demonstrate MoA and proof of concept of an off the shelf flexible combination option providing signals 1 and 2.

Description: Introduction Multiple myeloma (MM), relapsed or refractory (R/R) to standard of care therapies, represents a treatment indication with a significant unmet clinical need. Transcriptional activation of c-MYC through bromodomain and extra-terminal (BET) proteins contributes to the malignant phenotype of the disease. RO is a novel thienodiazepine, small molecule, non-covalent inhibitor of the BET family of bromodomains. Preclinical studies with BET inhibitors have demonstrated significant single agent in vivo activity in myeloma, accompanied by down-regulation of MYC and MYC target gene expression. We report results of a monotherapy phase 1b study of RO in R/R MM (NCT03068351). Methods Eligible pts with R/R MM included those treated with at least three prior lines of multiple myeloma therapy, including a proteasome inhibitor and an immunomodulatory agent, or who are double-refractory to a proteasome inhibitor and an immunomodulatory agent. Primary refractory myeloma pts were only allowed in the dose escalation portion of the study. In the dose escalation (part I), pts received subcutaneous (SC) escalating doses of RO (0.30-0.65 mg/kg) in a standard 3 + 3 design on days 1 - 14 of 21-day cycles to determine both the maximum tolerated dose (MTD) and recommended dose (RD). In the expansion cohort (part II), pts received RO as monotherapy at the RD level. Primary endpoint was safety (DLT, MTD, RD) and secondary endpoints included evaluation of pharmacodynamics (CD11b expression) and preliminary efficacy assessments based on IMWG criteria. Results Between June 2017 and April 2019, a total of 24 pts were enrolled in the US, the UK and Australia. 13 pts were enrolled in the dose escalation and 11 pts in the expansion part. The median age of pts was 65.5 years (range: 46 - 82 years). The study population was heavily pretreated with a median of 6 (3-9) prior therapies. Pts were refractory to immunomodulatory drugs (63%), proteasome inhibitors (46%), both (46%), or daratumumab (42%). 57 total cycles were administered, with a median of 2 (1-6) cycles per patient (pt). Two DLTs occurred in one pt in the 0.65 mg/kg cohort (thrombocytopenia grade 4, angina pectoris grade 3). The recommended dose is 0.65 mg/kg. Grade 3 treatment emergent AEs in ≥ 5% of pts were thrombocytopenia (11 pts [45.8%]), anemia (7 pts [29.2%]), fatigue (3 pts [12.5%]), injection site reaction, malaise, decreased appetite, and hyponatremia (2 pts [8.3%] each). 3 pts (12.5%) experienced a total of 4 AEs leading to discontinuation of the study treatment; these AEs were left ventricular dysfunction, fatigue, sepsis, and staphylococcal bacteremia (the latter two AEs occurred in the same pt). A total of 8 deaths (33.3%) were reported in the study, all as a consequence of progressive disease. The best overall response recorded was partial response in 4 pts (16.7 %), 3 of whom having received prior daratumumab. One pt experienced a minimal response, and stable disease was reported in 12 out of 24 (50%). There was no evidence for a dose-related increase in efficacy, though data are very limited (Table). Responses obtained during treatment with RO6870810 were short-lived and lasted for appr. 6 weeks. As evidence of target engagement, pharmacodynamic profiling demonstrated decreases in CD11b levels in peripheral blood mononuclear cells (Figure). Conclusions Treatment of MM pts with the BET inhibitor RO as monotherapy resulted in a high incidence of cytopenias, especially grade 3-4 thrombocytopenia and grade 3 anemia. However, none of these events led to study drug discontinuation. Cytopenias are a known side effect of BET inhibitors, with thrombocytopenia frequently reported as a DLT in various pt populations. Pts with NUT carcinoma, other solid tumors, or diffuse large B-cell lymphoma treated in the First in Man trial of RO had a low rate of cytopenias, indicating that the underlying disease and the extensive pre-treatment in MM may play a role in their occurrence (publication submitted). In this heavily pretreated R/R MM population, we have established 0.65 mg/kg as the recommended monotherapy dose. Pharmacodynamics effects were evident at this dose, but as monotherapy in this R/R MM cohort, response rates were low and less durable. Future drug combination approaches may result in an improved benefit / risk ratio.

Description: Current screening algorithms for type 2 diabetes (T2D) rely on fasting plasma glucose (FPG) and/or HbA1c. This fails to identify a sizeable subgroup of individuals in early stages of metabolic dysregulation who are at high risk for developing diabetes or cardiovascular disease. The Matsuda index, a combination of parameters derived from a fasting and postprandial insulin assay, is an early biomarker for metabolic dysregulation (i.e. insulin resistance/compensatory hyperinsulinemia). The aim of this analysis was to compare four widely available anthropometric and biochemical markers indicative of this condition [waist-to-height ratio (WHtR), hypertriglyceridemic-waist phenotype (HTW), triglycerides-to-HDL-C ratio (TG/HDL-C) and FPG] to the Matsuda index. This cross-sectional analysis included 2231 individuals with normal fasting glucose (NFG, n = 1333), impaired fasting glucose (IFG, n = 599) and T2D (n = 299) from an outpatient diabetes clinic in Germany and thus extended a prior analysis from our group done on the first two subgroups. We analyzed correlations of the Matsuda index with WHtR, HTW, TG/HDL-C and FPG and their predictive accuracies by correlation and logistic regression analyses and receiver operating characteristics. In the entire group and in NFG, IFG and T2D, the best associations were observed between the Matsuda index and the WHtR (r = − 0.458), followed by HTW phenotype (r = − 0.438). As for prediction accuracy, WHtR was superior to HTW, TG/HDL-C and FPG in the entire group (AUC 0.801) and NFG, IFG and T2D. A multivariable risk score for the prediction of insulin resistance was tested and demonstrated an area under the ROC curve of 0.765 for WHtR and its interaction with sex as predictor controlled by age and sex. The predictive power increased to 0.845 when FPG and TG/HDL-C were included. Using as a comparator the Matsuda index, WHtR, compared to HTW, TG/HDL-C and FPG, showed the best predictive value for detecting metabolic dysregulation. We conclude that WHtR, a widely available anthropometric index, could refine phenotypic screening for insulin resistance/hyperinsulinemia. This may ameliorate early identification of individuals who are candidates for appropriate therapeutic interventions aimed at addressing the twin epidemic of metabolic and cardiovascular disease in settings where more extended testing such as insulin assays are not feasible.
