Comeback time

DTIL covers with better money and partners similar territory/platforms, so just holding for positives before the necessary negatives.

The collab is focused on advancing multiple existing and additional next gen allo CAR-T programs directed to haematological malignancies. RHHBY has an exclusive license to anti-BCMA and anti-CD19/CD20 programs. Exclusive option to anti-CD70 and anti-BCMA/CD19 programs, as well as the right to nominate six additional candidates.

$62M in valuation, assets and cash, and selling for $1.2M market capitalization. There is a merger coming here for sure, they are preparing this for a reverse merger, as the recent filings suggest. Somebody is buying all those shares up!

It means whatever was in the S-8 has now become effective.

What does notice of effectiveness mean?

Not sure about Fraud. They just went out of business. Shut down operations and laid off everyone. Just didn't work out.

Plain and simple - FRAUD!!!!!

The CEO and BOD should be thrown in jail for stealing salaries for nothing.

Fraud!!

Leerink Partners should feel pretty stupid right about now.

T cells that show up in great numbers in head and neck tumors, but not in similar tissues of the mouth inflamed by common ailments such as gum disease.

It seems that this odd group of T cells have mixed up their highly specialized assignments within our immune systems and are now working to protect tumor cells.

''NT-125 is an investigational, autologous, fully-individualized, multi-specific TCR therapy targeting neoantigens for the treatment of advanced solid tumors. NT-125 is designed to contain up to five distinct neoantigen-specific TCRs per patient in a single cell product of highly functional engineered T cells, allowing multiple neoantigens presented by HLA class I and HLA class II molecules to be targeted with the goal to create a more impactful TCR therapy for more patients. NT-125 aims to reduce the probability of antigen escape and potentially maximize the depth and durability of clinical responses in a patient population with difficult to treat tumors and high unmet need.'' https://www.biospace.com/article/releases/neogene-therapeutics-announces-approval-of-clinical-trial-application-for-its-first-phase-1-trial-of-novel-fully-individualized-tcr-therapy-to-treat-advanced-solid-tumors/

Hopefully, this will play out similar to MRK buying Immune Design (from memory, they had to cut the workforce by ~20% after the lead program was discontinued).

From this: ''Using high-dimensional analysis of human ACT products, we identified a memory-progenitor CD39-negative stem-like phenotype (CD39-CD69-) associated with complete cancer regression and TIL persistence and a terminally differentiated CD39-positive state (CD39+CD69+) associated with poor TIL persistence.'' https://www.science.org/doi/10.1126/science.abb9847

There was a robust upregulation of T cells, macrophages, CD8+ T cells, and cytotoxic gene signatures in responders. Additionally, responders had an increase in Th1 gene signatures; an increase in TGF-ß1 gene expression was also noted. In distant lesions, the same gene signatures were upregulated.

Mellman described published work linking PD-1 and CD28 signaling through the phosphatase Shp2. Evidence also showed that myeloid cells, particularly dendritic cells in the TME, were the critical source of PD-L1 ligand.

The reason high-dose cyclophosphamide is able to ablate the effector cells without destroying hematopoietic stem cells is that the earliest stem cells (but not lymphocytes) contain high levels of aldehyde dehydrogenase conferring resistance to the cytoxic properties of cyclophosphamide. Dr. Brodsky and his colleagues in neurology and rheumatology are applying this approach in other severe autoimmune disorders including, scleroderma, myasthenia gravis, multiple sclerosis and autoimmune hematologic disorders.

Analysis of severe lymphodepletion on the day of TIL infusion as measured by absolute lymphocyte counts showed similar values when comparing the high-dose and low-dose cyclophosphamide/fludarabine groups (0.029 ± 0.036 K/L [median, 0.020 K/L] vs 0.024 ± 0.017 K/L [median, 0.025 K/L]).
