They will use the standard flu/cy as part of the conditioning regime, but also either cyclophosphamide or bendamustine. They have been testing the integration of the ADR tech in next-gen iPSC-derived CD8+ CAR T-cells, which could allow conditioning-free therapy. Adding additional edits could prevent rejection as well https://www.biorxiv.org/content/10.1101/2023.10.09.557143v1.full

Make sense. 100% depletion of B cells probably not ideal outcome anyway.

In the second half, they expect to read-out initial PhI data for the first 3-5 patients treated with FT819 for moderate to severe SLE. They seek to administer FT819 without fludarabine and instead with commonly used treatment regimens for autoimmune diseases. They seek to demonstrate the potential of the proprietary ADR tech. Specifically, they expect to read-out 3-5 patients treated with FT522 in the PhI for B-cell lymphoma. They seek to broadly investigate FT522 without conditioning chemo for treatment of various B-cell autoimmune diseases. They seek to establish an initial clinical proof-of-concept with the first 3-5 patients treated with FT825 in the PhI for advanced solid tumours. Also, plan to disclose new target(s) and product configurations for at least two next-gen product candidates.

(OT) Artec Biotech is built upon methods for differentiating iPSCs into NK cells, as well as proprietary modifications. One example is the alteration of checkpoint receptors, such as PD-1 KO, which will be used for ART-002. The lead is ART-001, an unmodified NK product.

Although iPSC-NKs and PB-NKs of the same donor exhibited similar gene expression profiles, analysis revealed notable differences in genes that are important for NK cell function. Some of these genes were highlighted. Given the success of checkpoint inhibition in treating certain types of cancer, they evaluated checkpoint receptor expression in iPSC-NKs compared to PB-NKs. As demonstrated by a recent study, the expression of multiple checkpoint inhibitors was significantly higher in CD73+ cells, and the frequency of CD73+ cells correlated with larger tumour size in breast cancer patients https://www.jci.org/articles/view/128895

In their differentiation system, they produced NKs with down-regulated CD73 expression.

The next gene of interest was PTGER4, which encodes prostaglandin E2 receptor 4 (EP4). In NK cells, the binding of prostaglandin E2 to the receptor can initiate immunosuppression. In contrast, EP4 inhibition has been shown to enhance NK antitumour activity https://www.tandfonline.com/doi/full/10.1080/2162402X.2021.1896643

EP4 was down-regulated.

TIGIT was another gene of focus. Although not expressed in iPSC-NKs, it was highly expressed in PB-NK control. Overall, TIGIT is variably expressed in human NKs. Notably, NKs with lower TIGIT expression have exhibited higher cytokine secretion capability, degranulation activity, and cytotoxic potential https://onlinelibrary.wiley.com/doi/10.1002/eji.201545480

Furthermore, blocking TIGIT expression via monoclonal antibodies alleviated NK exhaustion https://www.nature.com/articles/s41590-018-0132-0

Similar to TIGIT, cytokine-inducible Src homology 2–containing protein (CIS), encoded by the CISH gene, is also involved in cytokine secretion. CIS is a member of the suppressor-of-cytokine signaling family of proteins. CISH deletion in either iPSC-NKs or PB-NKs increases their sensitivity to IL-15 and enhances JAK/STAT and mTORC1 signaling. This leads to increased NK metabolic fitness that contributes to an improved antitumour response https://ashpublications.org/blood/article/137/5/624/463715/Targeting-a-cytokine-checkpoint-enhances-the

Their iPSC-NKs have significantly down-regulated CISH expression compared to PB-NKs.

Aside from direct mechanisms that tumours employ to down-regulate NK function, the tumour microenvironment also impairs NK function by negatively affecting NK metabolism https://www.frontiersin.org/articles/10.3389/fimmu.2019.02278/full

Enhancing NK metabolic functionality is currently being pursued as one of the avenues for increasing NK cell activity against tumours https://www.pnas.org/doi/10.1073/pnas.2107507118

Considering this, they further evaluated the metabolic profile of iPSC-NKs and PB-NKs. The assessment focused on significantly expressed genes, which impact NK metabolic function. The following genes showed up-regulation in iPSC-NKs: Slc2a1 (involved in glucose transport), Slc7a5 (an amino acid transporter), Slc3a2/CD98 (an amino acid transporter), and TFRC/CD71 (involved in receptor-mediated iron uptake). These data yield insight into the efficacy of iPSC-NKs because nutrient transport is essential and increased expression of nutrient transporters promotes an increased metabolic rate, as well as elevated NK activity https://stemcellres.biomedcentral.com/articles/10.1186/s13287-021-02377-8

(OT) oNKo-innate is a discovery-stage biotech company dedicated to target identification and preclinical IO (drug) development.

In this, the functional genomics and target discovery team have used their platform to perform enrichment screens in primary human NK cells, identifying novel IL-15 axis regulators that contribute to survival and persistence. Phenotypic screens similarly revealed regulators of NK cell cytotoxicity and interferon gamma production. By validating these targets, the team has demonstrated that they are able to regulate various aspects of NK and CAR-NK cell function.

Using CRISPR screening of metabolic genes, they found that KEAP1 played an important role in the pro-inflammatory activity of macrophages through inhibiting the production of itaconate. As ACOD1 is the sole enzyme to generate itaconate, ACOD1 knockout promoted pro-inflammatory activity of macrophages and enhanced the function of CAR-Ms derived from iPSCs https://www.nature.com/articles/s41467-023-41470-9

New pipeline

In that paper they were detectable for only 48 hours. NKs have an effective half-life of 1-2 weeks, memory-like longer, with early data (in H&N with anti-CTLA-4* and N-803) showing persistence out to at least 40 days.

* CTLA-4 blockade seems to impact phenotype with a skewing towards CD16+CD57+.

Yes, that was one of at least five (from memory) trials testing aNKs (non-engineered NK-92s).

In metastatic pancreatic IBRX tested low-dose nab-paclitaxel, gemcitabine, aldoxorubicin, cyclophosphamide, low-dose SBRT, N-803 (an IL-15 superagonist) and PD-L1 CAR-NKs.

In all patients (3rd to 6th line) mOS is 5.8 months; median PFS 2.3 months. In 3rd line, mOS is 6.3 months. While this exceeds historical results, there were no controls.

Going forward (for other types), they plan on adding a number of other agents, including a heterologous prime-boost vaccine.

It is given weekly. So persistence is not an issue.

It is a transformed cell line, so must be irradiated prior to administration. In previous trials, this has (perhaps) been responsible for the limited persistence observed, only a few days https://www.isct-cytotherapy.org/article/S1465-3249(13)00603-8/fulltext
