In work conducted at China Pharmaceutical University, synthesis and optimization of a new series of cyclin-dependent kinase 9 (CDK9) inhibitors bearing a flavonoid scaffold led to the identification of compound [I] as the lead candidate, with IC50 of 6.7 nM for CDK9 and >80-fold selectivity over CDK2 and most other CDK family members.
Researchers from Exscientia plc presented preclinical data for the novel reversible LSD1 inhibitor EXS-74539, being developed as a monotherapy or in combination with standard of care for the treatment of oncology and hematology indications including acute myeloid leukemia (AML) and small-cell lung cancer.
Caribou Biosciences Inc. has received FDA clearance of its IND application for CB-012, an allogeneic anti-C-type lectin-like molecule-1 (anti-CLL-1) chimeric antigen receptor (CAR) T-cell therapy. CLL-1 is highly expressed on acute myeloid leukemia (AML) cells and leukemic stem cells, but it is not expressed on hematopoietic stem cells.
Recurrent driver mutations in FMS-related receptor tyrosine kinase 3 (FLT3) occur in around one-third of patients with de novo acute myeloid leukemia (AML). Although most FLT3 mutations are secondary events in leukemogenesis, they are associated with accelerated clonal expansion and disease progression, and treatment with the tyrosine kinase inhibitor midostaurin has been shown to increase patients’ long-term survival. However, the efficacy of FLT3 inhibitors in eliminating FLT3-mutated clones is variable.
Finding suitable antigens for immunotherapy of myeloid malignancies, particularly acute myeloid leukemia (AML), is an urgent clinical need. Most AML candidate targets, including CD123, are co-expressed by hematopoietic stem and progenitor cells (HSCPs), with the subsequent risk of myelosuppression associated with myeloid cell-targeted chimeric antigen receptor (CAR) T therapy.
Syndax Pharmaceuticals Inc. is gearing up for a U.S. FDA filing by the end of 2023 on the back of positive data from a pivotal phase I/II study testing menin inhibitor revumenib in adult and pediatric patients with relapsed/refractory KMT2A-rearranged acute myeloid leukemia and acute lymphoid leukemia.
Researchers from Fudan University and affiliated organizations presented the discovery of novel PIM kinase inhibitors for the treatment of acute myeloid leukemia (AML). A literature-aided molecular hybridization strategy was applied to synthesize a structurally novel compound, based on an N-pyridinyl amide scaffold. Subsequent optimization showed that the positional isomerization of pyridine N toward to Lys67 resulted in a decrease of potency while increased freedom of solvent fragment toward Asp128/Glu171 led to an increase in activity.
I-Mab Biopharma Co. Ltd. has regained full rights to its CD47 antibody program from Abbvie Inc., including lemzoparlimab, the most advanced candidate. The move, disclosed in a Sept. 22 U.S. SEC filing, eliminates the potential $1.295 billion in milestones associated with the amended collaboration deal signed in 2022.
