WEXFORD, Pa., Feb. 7, 2024 /PRNewswire/ -- Coeptis Therapeutics Holdings, Inc. (Nasdaq: COEP) (the "Company" or "Coeptis"), a biopharmaceutical company developing innovative cell therapy platforms for cancer and infectious diseases, today announced plans to pursue DVX201, its proprietary allogeneic stem cell expansion and directed differentiation platform of unmodified natural killer (NK) cell therapy, as an antiviral treatment addressing various respiratory viral infections that lead to hospitalization, including the "tripledemic" of influenza, COVID-19 and respiratory syncytial virus (RSV).

Key Points: 
  • DVX201 is produced by pooling CD34+ cells isolated from multiple cord blood donations to increase lot size and immune system diversity.
  • Importantly, doses undergo stringent testing including a potency assay before treatment, to assess their ability to kill virally infected cells.
  • Additionally, DVX201 does not contain T-cells, which significantly reduces the possibility for major rejection by patients, which is a major concern for some cell therapy products.
  • DVX201, the first-ever allogeneic, cord-blood derived NK cell therapy generated from pooled donor CD34+ HSPC cells, has the potential to offer significant support to patients and to our strained healthcare system."

    Intronic editing enables lineage specific expression of therapeutics relevant for HSPC gene therapy.
  • TALEN®-mediated intron editing of the CD11b locus results in the lineage-specific expression of a reporter transgene in myeloid cells, with negligible expression in HSPC or other cellular subsets in vitro and in vivo.
  • We believe this intron editing approach could be disruptive in HSPC gene therapy and brain delivery of multiple therapeutics.
  • Using a combination of scRNA sequencing and multiple genomic read out methodologies, we demonstrate that the mutant HBB gene can be efficiently corrected in HSPCs by TALEN®-mediated gene editing coupled to non-viral gene delivery (ssODN) with a low risk of generating β-thalassemic RBCs.

CHOP Researchers Improve Fitness of Cells Used in Cell Transplants

PHILADELPHIA, Sept. 27, 2023 /PRNewswire/ -- A readily available, inexpensive small molecule drug can improve the fitness of hematopoietic stem and progenitor cells (HSPCs) that are modified outside of the body, potentially improving the success of procedures like ex vivo gene therapy, according to a new study by researchers at Children's Hospital of Philadelphia (CHOP). The study, published in the journal Blood, showed that targeting components in the cells called extracellular vesicles (EVs) relieves the stress on cells when outside of the body, improving their performance when they are transplanted back inside.

Key Points: 
  • Hematopoietic stem cell transplantation (HSCT) involves the transfer of HSPCs from a donor to patients with both benign and malignant diseases.
  • However, maintaining the fitness of these cells outside of the body poses a challenge, and any loss of fitness introduces the risk that the cells will not properly restore the blood and immune cell system in patients.
  • One process that we now learn contributes to cell equilibrium is the secretion of EVs, which are important for delivering messages from cell to cell and maintaining proper cell function.

Key Points: 
  • The preclinical data are published in Blood Advances, a peer-reviewed journal of the American Society of Hematology.
  • The dual strategy demonstrated powerful antitumor efficacy against AML targets without any relevant toxicity on hematopoietic stem and progenitor cells (HSPCs) and endothelial cells.
  • Specifically, the researchers found:
    CD123 and/or CD33 knockout impairs leukemia growth by modulating multiple cancer pathways in a model of NPM1-mutated AML.
  • Low affinity CAR-CIK cells preserve antileukemic efficacy in vitro and improve antitumor control in vivo.
