Abstract
Natural killer (NK) cells are a vital component of cancer immune surveillance. They provide a rapid and potent immune response, including direct cytotoxicity and mobilization of the immune system, without the need for antigen processing and presentation. NK cells may also be better tolerated than T cell therapy approaches and are susceptible to various gene manipulations. Therefore, NK cells have become the focus of extensive translational research. Gamida Cell's nicotinamide (NAM) platform for cultured NK cells provides an opportunity to enhance the therapeutic potential of NK cells. CD38 is an ectoenzyme ubiquitously expressed on the surface of various hematologic cells, including multiple myeloma (MM). It has been selected as a lead target for numerous monoclonal therapeutic antibodies against MM. Monoclonal antibodies target CD38, resulting in the lysis of MM plasma cells through various antibody-mediated mechanisms such as antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity, and antibody-dependent cellular phagocytosis, significantly improving the outcomes of patients with relapsed or refractory MM. However, this therapeutic strategy has inherent limitations, such as the anti-CD38-induced depletion of CD38-expressing NK cells, thus hindering ADCC. We have developed genetically engineered NK cells tailored to treat MM, in which CD38 was knocked-out using CRISPR-Cas9 technology and an enhanced chimeric antigen receptor (CAR) targeting CD38 was introduced using mRNA electroporation. This combined genetic approach allows for an improved cytotoxic activity directed against CD38-expressing MM cells without self-inflicted NK-cell-mediated fratricide. Preliminary results show near-complete abolition of fratricide with a 24-fold reduction in self-lysis from 19% in mock-transfected and untreated NK cells to 0.8% of self-lysis in CD38 knock-out CAR NK cells. Furthermore, we have observed significant enhancements in CD38-mediated activity in vitro, resulting in increased lysis of MM target cell lines. CD38 knock-out CAR NK cells also demonstrated significantly higher levels of NK activation markers in co-cultures with both untreated and αCD38-treated MM cell lines. These NAM-cultured NK cells with the combined genetic approach of CD38 knockout and addition of CD38 CAR represent a promising immunotherapeutic tool to target MM.

Abstract
BackgroundAdoptive transfer of Natural Killer cells (NKs) is a growing area of innovation in cancer immunotherapy. Nicotinamide (NAM), an allosteric inhibitor of NAD-dependent enzymes, has been shown to preserve cell function and prevent differentiation in ex vivo culture of NK (NAM-NK) and other cells. Clinical responses were observed in a Phase 1 trial of NAM-NK (GDA-201) in patients with refractory non-Hodgkin lymphoma (Bachanova, et. al., Blood 134:777, 2019). We now characterize the mechanisms underlying the activity of NAM-NK by exploring their phenotype, functionality, and antitumor activity.MethodsCD56 positive cells obtained from healthy donors were cultured for 14 days with IL-15 in the presence or absence of NAM (7 mM). Cell-surface antigens were characterized using flow cytometry (FACS). Mitochondrial reactive oxygen species (ROS) were measured using MitoSox-based FACS. In vitro killing of tumor cells was evaluated by FACS after co-culture of NAM-NK with HER-2-positive A549 (lung adenocarcinoma) or SKOV-3 (ovarian cancer) cells in the presence or absence of trastuzumab; NK cell CD107a and intracellular IFNγ, TNFα, and GM-CSF were also measured by FACS. In vivo activity was determined using a subcutaneous tumor model in NSG mice injected with A549 cells (5x106 sc) and treated with NAM-NK cells (20x106 cells ip/day) on Day 9–12 with IL-2 (300 ug ip), with or without trastuzumab (100ug ip).ResultsCharacterization of cell surface markers revealed elevated CD56, CD62L, and CD49a and decreased CD16, CD57, and NKp80 in NAM-NK compared to NK cultured without NAM. CD200R and LAG3 were decreased. NAM-NKs also demonstrated decreased mitochondrial superoxide formation triggered by H2O2 oxidative stress.NAM-NK co-cultured with A549 and SKOV-3 cells had increased expression of the degranulation marker CD107a and the proinflammatory cytokines INF-γ, TNF-α, and GM-CSF compared to NK without NAM, and demonstrated increased cytotoxicity in the presence and absence of trastuzumab. Finally, NAM-NK inhibited A549 tumor growth in vivo; tumor growth inhibition was potentiated in the presence of trastuzumab and greater than with trastuzumab alone.ConclusionsThese data suggest that NAM rejuvenates cultured NK, generating activated and potent NK cells. NAM-NK (GDA-201) display a distinct phenotype similar to cytokine-induced memory like (CIML) NK, but with downregulation of immune checkpoint inhibitors such as CD200R and LAG3. In addition, NAM-NK are greatly resistant to ROS−a known mechanism of tumor resistance−and highly cytotoxic in in vitro and in vivo assays. The promising potential of GDA-201 as an anticancer immunotherapy is being explored further in clinical trialsEthics ApprovalWe hereby declare that the collection of the Apheresis units in the three participating institutes (sites) has been done under an approved clinical study that meets the following requirements:1.

Abstract
BackgroundNicotinamide (NAM), an allosteric inhibitor of NAD-dependent enzymes, has been shown to preserve cell function and prevent differentiation in ex vivo cell culture. GDA-201 is an investigational natural killer (NK) cell immunotherapy derived from allogeneic donors and expanded using IL-15 and NAM. In previous preclinical studies, NAM led to increased homing and cytotoxicity, preserved proliferation, and enhanced tumor reduction of NK cells. In a phase I clinical trial, treatment with GDA-201 showed tolerability and clinical responses in patients with refractory non-Hodgkin lymphoma (NHL) (Bachanova, et. al., Blood 134:777, 2019). While NAM is known to affect cellular metabolism and participate in 510 enzymatic reactions −in 66 as an inhibitor or activator− its mechanism of action and role in GDA-201 cytotoxicity is unknown.MethodsIn order to define the network of intracellular interactions that leads to the GDA-201 phenotype, flow-cytometry, next generation sequencing (NGS), and liquid chromatography–mass spectrometry (LC-MS)-based metabolite quantification were performed on NK cells cultured for 14 days with IL-15 and human serum in the presence or absence of NAM (7 mM). Artificial Intelligence (AI) machine learning analysis was applied by Pomicell in order to analyze the data using the Pomicell databases supporting data extracted from multiple origins including scientific articles organized using natural language processing tools. AI training was done using a combined algorithm designed to blindly explain and predict the transcriptomic and metabolomic (omics) profile.ResultsOmics analyses defined 1,204 differentially expressed genes, and 100 significantly modified metabolites in the presence of NAM. An in silico model was created that successfully predicted the experimental data in 83% of the cases. Upregulation of TIM-3 expression in GDA-201 was predicted to be mediated by inhibition of IL-10 and SIRT3, via CREB1/HLA-G signaling and adrenoceptor beta 2 (ADRB2) upregulation. Adenosine metabolite reduction supports this and suggests dopaminergic activation of NK cytotoxicity. Upregulation of CD62L in the presence of NAM was predicted to be mediated by transcription factor Dp-1 (TFDP1) via dihydrofolate reductase (DHFR) activation and intracellular folic acid reduction. Interferon-gamma and CASP3 modulation (via JUN and MCL1, respectively), via PPARa inhibition, support that finding.ConclusionsIn conclusion, AI machine learning of transcriptome and metabolome data revealed multiple pleiotropic metabolic pathways modulated by NAM. These data serve to further elucidate the mechanism by which NAM enhances cell function, leading to the observed cytotoxicity and potency of GDA-201.Ethics ApprovalWe hereby declare that the collection of the Apheresis units in the three participating institutes (sites) has been done under an approved clinical study that meets the following requirements:1.
