The key to success is CXCR2 and 1xx for FATE CART. MSK 1xx CD19 auto trial showed ORR at 25M cells dose, so trogocytosis, persistence and proliferation must be optimal to be effective.

One of the potential downsides of inhibiting (CD16(a)) shedding is that it could slow NK detachment and reduce serial killing https://rupress.org/jcb/article/217/9/3267/120862/Shedding-of-CD16-disassembles-the-NK-cell-immune

It was shown some years ago that CD64 binds to the same IgGs, but with at least 2-3 orders of magnitude higher affinity than CD16(a). Based on that data, I think they should switch to using it and look to add additional modifications https://jhoonline.biomedcentral.com/articles/10.1186/s13045-023-01455-z

They (and others) need to learn from the (early) mistakes of FATE.

Trogocytosis can impact both CAR-T, as well as CAR-NK therapies. Strategies to overcome trogocytosis-induced antigen loss, fratricide and/or cell exhaustion include, pharmacological targeting, modulating CAR affinity, ''armouring,'' modulating the signalling domain(s), or using a dual CAR strategy. Some preclinical data on the latter https://www.nature.com/articles/s41591-022-02003-x

The functional effects of trogocytosis remain to be elucidated, however, it has been shown to interfere with successful CAR-mediated antitumor responses as it promotes tumor antigen escape as well as CAR T cell dysfunction due to fratricide killing

Translational data from the PhI B-cell lymphomas trial demonstrated primary, secondary and tertiary tissue trafficking and clearance of CD19+ cells. That should help enable an immune reset in autoimmune diseases.

Shoreline has let go of an undisclosed number of employees tied to a cell therapy project with GILD's Kite Pharma, Endpoints News reported. Shoreline CEO declined to disclose the number of workers that were laid off and said the future of the collaboration is still ''to be determined.''

The two had agreed to change the focus of their partnership. Instead of developing a CAR-iNK cell therapy for B-cell lymphomas (either CD19-targeted or CD19/CD20-targeted), they switched to autoimmune diseases. Shoreline already had a pre-IND meeting with the FDA and was recruiting US and international clinical trial sites for a PhI trial in autoimmune diseases. They were going to enter the clinic in the coming months and planned to give Kite the possibility of opting in after concluding the trial.

As Kite went through leadership changes in recent years, Shoreline's CEO said the two had a ''wonderful collaboration,'' including being aligned with the new [autoimmune] focus for that therapy. They agreed on ''90%'' of the terms in an adjusted deal, including another potential equity investment from GILD, but they couldn't come to an agreement on any ''back-end economics.'' Shoreline believed it deserved a ''larger portion on [the] upside.''

FT819 can act as a ligand sink and change DC/CD8, NLR ratios in 2nd lymphoid and inflammed tissues. Creating a new Bronx so to speak.

CXCR4 is critical for the organization of secondary lymphoid tissues, such as lymph nodes and spleen, where immune responses are initiated.
Dysregulation of CXCR4 signaling may contribute to abnormal germinal center reactions and the development of autoreactive immune cells.

Maybe they thought that better penetration into the bone marrow could allow for greater effectiveness in targeting certain types, such as B-ALL. CXCR4 is critical for bone marrow homing of T-cells https://onlinelibrary.wiley.com/doi/10.1002/eji.201747438 https://journals.aai.org/jimmunol/article/193/3/1013/108777/Cutting-Edge-CXCR4-Is-Critical-for-CD8-Memory-T

I know they have a patent for hematopoietic stem or progenitor cells being contacted with an agent that increases CXCR4 gene expression in the cells.

However, the iTs (that are either contacted with that agent or not) express high levels of Fas https://www.jci.org/articles/view/121491 https://www.nature.com/articles/s41467-017-00784-1 https://www.nature.com/articles/nm.3541

The key is in CART and neutrophil interactions within the draining lymph nodes. Neutrophils build TME and suppress CD8+ /NK via Treg. For the primary tumor, CART will need mAb to deal with antigen escape.

Metastatic cancer cells can develop multiple (suppressive) mechanisms that enable the evasion of NKs, such as this https://www.cell.com/cell-reports/fulltext/S2211-1247(24)01206-3

In one patent the same group goes on to show that EP2/EP4 KO enables the NKs to secrete chemokines, such as XCL1 that recruit key immune cell populations required for T-cell mediated tumour immunity https://www.cell.com/cell/fulltext/S0092-8674(18)30039-4

In another paper, a different group identifies IGSF8 as a new immune checkpoint that suppresses NKs (and dendritic cells) in antigen presentation deficient cancer cells https://www.cell.com/cell/abstract/S0092-8674(24)00355-6

So I think the right combination of edits will be needed to overcome trafficking, infiltration, potency, expansion, persistence, while also preventing exhaustion/dysfunction, suppression, tackle antigen heterogeneity and evasion.

For many, many years the focus was on the Vd2 subset, but recent evidence in multiple tumours showed associations of other subsets (Vd1 and/or Vd3) with increased patient survival and/or clinical benefit https://www.nature.com/articles/s43018-022-00376-z https://www.science.org/doi/10.1126/scitranslmed.aax9364

NK is fine for SLE since the depletion of the memory B cells is the goal. For solid, creating polyclonal T cells with memory phenotype is the key for OR duration.
From ChatGPT:
Studies with 1XX CAR T cells highlight their enhanced capacity for cytokine production and survival, suggesting a stronger potential for interaction with and modulation of DCs compared to conventional CAR T cells. Dendritic cells in the TME can process these antigens and cross-prime endogenous T cells against TAAs, creating a polyclonal immune response that complements the CAR T-cell activity.

Unlike NKs, the differentiation of T-cells from iPSCs is (far) more complex. Also, the NKs from iPSCs are more comparable functionality to PB/CB NKs, and can kill independent from the CAR.

It would make sense to test the two https://aacrjournals.org/cancerimmunolres/article/7/3/363/469550/NK-Cells-Expressing-a-Chimeric-Activating-Receptor

But there are still hurdlers (for the NKs) to overcome, including persistence and lack of expansion. The use of an IL15-RF may impair NK functions as well https://insight.jci.org/articles/view/96219 https://www.pnas.org/doi/10.1073/pnas.1012128107

Why bother with CARNK after they licensed 1xx from MSK. CAR T 1xx lowers the activation and energy req'd to survive in the hypoxic TME. More durable and lower CRS CART therapy will beat ADC in terms of AE and OS long term.

I am looking for some FT536 P1 data to figure out why they decided on 3 day dosing at U of M?

Either based on data from other trials and/or the biology of NKs (they do not typically expand upon encounter with antigen and lack long-term persistence). It looks to be a compressed dosing schedule, which could extend exposure and increase Cmax levels.

That poster only listed 3 pts dosed at 100M cells mono, how about higher dosages?

Monotherapy escalation was continuing at 300 million cells/dose. So I assume (rightly or wrongly) that those two patients had been treated at this dose level. From memory, they were going to test at least a third dose level as well (500 million cells/dose). Also, had an option to add IL-2 once the MTD had been reached.

Improved Memory Phenotypes: The reduced stress allows a greater proportion of 1XX CAR T cells to retain central memory and effector memory phenotypes, which are crucial for long-term persistence and functionality.
Lower Cytokine Production: By producing cytokines at more moderate levels, 1XX CAR T cells avoid the excessive metabolic demands and inflammatory feedback loops that can lead to early cell death or dysfunction.
the higher stress in CAR T cells can make them more susceptible to NK cell-mediated clearance.
