Journal, IO biomarker: Optimization of therapeutic T cell expansion in G-Rex device and applicability to large-scale production for clinical use. (Pubmed Central) - Apr 26, 2022
Given the need to increase the efficiency and safety of large-scale T cell expansion for clinical use, we have optimized the method to expand in G-Rex devices both cytokine-induced killer cells (CIKs) from peripheral or cord blood and blinatumomab-expanded T cells (BETs)...CIK-Gs also showed therapeutic activity in vivo in the Ph pre-B ALL-2 model in mice. The expansion of both CIKs and BETs in G-Rex was validated in good manufacturing practices (GMP) conditions, and we plan to use G-Rex for T cell expansion in future clinical studies.

For the remaining drugs, including commonly used agents such as cisplatin, cytarabine, ifosfamide, and methotrexate, pharmacological evidence for dosing in infants was limited or non-existent: grades C and D were scored for 10 and 2 drugs, respectively. The review provides clinically relevant evidence-based dosing guidance for cytotoxic drugs in neonates and infants.

Considering the number of oncology medicinal products available for adults and the rarity of paediatric cancers, prioritisation based on scientific evidence and medical need, as well as international collaboration, is critical. Herein, we review the current status of drug development for children with leukaemia and lymphoma, excluding cellular therapy despite its well-known significance.

Journal: Trispecific T-cell engagers for dual tumor-targeting of colorectal cancer. (Pubmed Central) - Apr 9, 2022
Retargeting of T lymphocytes toward cancer cells by bispecific antibodies has demonstrated its therapeutic potential, with one such antibody approved for the treatment of acute lymphoblastic leukemia (blinatumomab) and several other in clinical trials...In addition, it was less efficient at killing single-positive target cells than the corresponding bispecific controls, leading to potentially enhanced tumor specificity. Moreover, dual targeting of two tumor-associated antigens may contribute toward preventing the tumor escape by antigen loss caused by selective pressures from conventional single-targeting T-cell engagers, and may help to overcome antigenic heterogeneity.

Bispecific antibody-based immunotherapies have gained momentum in preclinical and clinical investigations following the regulatory approval of the T cell-redirecting antibody blinatumomab...Currently, there are more than 50 bispecific antibodies under clinical development for a range of indications, with promising signs of therapeutic activity. We also discuss two approaches for in vivo secretion, direct gene delivery and infusion of ex vivo gene-modified cells, which may become instrumental for the clinical application of next-generation bispecific immunomodulatory antibodies.

Additionally, the availability of highly effective agents for MRD eradication, such as blinatumomab, inotuzumab ozogamicin, and chimeric antigen receptor (CAR) T-cell therapies, enabled the development of frontline regimens capable of eradicating MRD early in the treatment course. While long-term follow-up of this approach is lacking, it has the potential to significantly reduce the need for intensive post-remission treatments, including allogeneic bone marrow transplantation, in a significant proportion of patients with ALL.

Among them, the US Food and Drug Administration (FDA)-approved blinatumomab (BLI) is very effective in eliminating the minimum residual disease (MRD) of acute lymphoblastic leukemia (ALL), resulting in long-term remission in many individuals...These results suggest that the i.m. MC technology can eliminate the physical and financial burdens of i.v. delivered BLI without compromising anticancer efficacy and that cancer can be treated as easily as injecting a vaccine. This, together with other superior MC features, such as safety and affordability, suggests that the i.m. MC BsAb technology has great clinical application potential.

IL-12 overcomes T-cell immune suppression by the B-ALL microenvironment (Section 39) - Mar 9, 2022 - Abstract #AACR2022AACR_5503;
In addition to suppressing CD44 and CD107b, we also found that B-ALL-secreted factors also suppress the activation of signaling pathways downstream of the TCR.Considering clinical implications of this discovery, we further explored IL-12 ex vivo in combination with the clinically approved bi-specific T-cell engager, blinatumomab. Notably, B-ALL-secreted factors reduced blinatumomab-mediated T-cell lysis of target cells, which was restored with recombinant IL-12 treatment.Overall, this data shows the potential for IL-12 to be used as an immunotherapeutic in conjunction with other current therapies to overcome T-cell suppression by B-ALL.
