SK Biopharmaceuticals Co. Ltd. has signed a research collaboration agreement with Proen Therapeutics Inc. to further extend its oncology research capability and expand its pipeline of radiopharmaceutical therapies.
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.
In tumoral cells, the modulation of the G1/S phases of cell cycle is destabilized by amplification and high expression of cyclin E (CCNE) or by mutation or loss of retinoblastoma 1 (RB1) gene. Cancer cells meeting these characteristics have been sown to be highly sensitive to cyclin-dependent kinase 2 (CDK2) depletion.
Ideaya Biosciences Inc. has nominated IDE-251, a dual KAT6/7 inhibitor targeting 8p11 amplification tumors in breast and lung cancers, as a development candidate. IDE-251 is an equipotent, highly selective, small-molecule dual inhibitor of KAT6 and -7, both of which have been shown to support cancer cell survival.
Glutathione S-transferase (GSTP) is an enzyme involved in the detoxification of several xenobiotics such as tobacco carcinogens or cisplatin drugs and is overexpressed in KRAS-mutant lung, colon and pancreatic cancer, among others. The upregulation of GSTP may partially contribute to chemotherapy and radiotherapy resistance.
A year after manufacturing issues resulted in a complete response letter for cosibelimab, the U.S. FDA approved Checkpoint Therapeutics Inc.’s drug, branded Unloxcyt, as the first anti-PD-L1 antibody for use in metastatic or locally advanced cutaneous squamous cell carcinoma patients who are not candidates for curative surgery or curative radiation.
