The curtain is coming down on one of Europe’s longest-established biopharmas, with Novartis AG announcing it is to shut Morphosys AG’s facilities, following its 2024 acquisition of the one-time antibody pioneer for $2.9 billion. The closure of sites in the U.S. and Germany by the end of 2025 will affect 330 employees.
KAT2A is a histone acetyltransferase that functions as a transcriptional activator which, together with its paralogue KAT2B, is markedly overexpressed in acute myeloid leukemia (AML) compared to in hematopoietic progenitor cells.
Interleukin-18 (IL-18) is a pro-inflammatory cytokine that modulates innate and adaptive immune responses. Decoy-resistant IL-18, DR-18, from Simcha Therapeutics Inc., is an engineered IL-18 cytokine able to interact with the IL-18 receptor but resistant to IL-18-binding protein (IL18BP), which is a negative regulator of IL-18 signaling, thus overcoming the antitumoral efficacy limitation seen with recombinant IL-18.
Kura Oncology, Inc. and Kyowa Kirin Co. Ltd.’s selective oral menin inhibitor ziftomenib showed encouraging data across multiple studies, the most encouraging of which were in combination with other standard of care therapies in patients with NPM1-mutant and KMT2A-rearranged acute myeloid leukemia.
Cathepsin G (CTSG) is overexpressed and aberrantly localized for antigen presentation on acute myeloid leukemia blasts and stem cells compared to normal hematopoietic progenitors. Earlier this year, Crossbow Therapeutics Inc. announced the nomination of its first development candidate, CBX-250, a TCR-mimetic (TCRm) bispecific T-cell engager (TCE) antibody targeting a CTSG peptide-human leukocyte antigen (pHLA) complex and CD3.
The lack of acute myeloid leukemia-specific antigens is one of the challenges for targeted immunotherapy together with on-target off-tumor toxicities due to the expression of the target in normal myeloid cells. A subset of T cells – Vδ2 T-cells – which represent ~5% of the T-cell population in healthy donors, are seen as part of emerging immunotherapeutic strategies.
Kura Oncology, Inc. and Kyowa Kirin Co. Ltd.’s selective oral menin inhibitor ziftomenib showed encouraging data across multiple studies, the most encouraging of which were in combination with other standard of care therapies in patients with NPM1-mutant and KMT2A-rearranged acute myeloid leukemia.
The effective targeting of RAS-mutant acute myeloid leukemia (AML) still remains a challenge; RAS mutations are tied to relapse to targeted therapy, such as resistance to FLT3 inhibitors due to the RAS/MAPK pathway, for example.
With the aim of developing an effective and more tolerable conditioning for hematopoietic stem cell transplantation (HSCT), researchers from Molecular Partners AG applied the proprietary ankyrin repeat protein (DARPin) platform to generate a novel multi-specific Switch-DARPin candidate, MP-0621.
