Solve Therapeutics Inc. has identified antibody-drug conjugates comprising an UC-961 antibody or a tyrosine-protein kinase transmembrane receptor ROR2 (ROR2)-targeting antibody covalently linked to exatecan through a linker reported to be useful for the treatment of cancer.
Cstone Pharmaceuticals Co. Ltd. has filed a clinical trial application in Australia seeking to initiate a first-in-human study of CS-2009 for solid tumors. The company plans to initiate a multi-regional trial for CS-2009 in Australia early next year, followed by expansion into China and the U.S.
Radiopharm Theranostics Ltd. has been granted Belberry Human Research Ethics Committee (HREC) approval in Australia to initiate a first-in-human phase I therapeutic study of 177Lu-labelled RAD-202 (177Lu-RAD-202) for the treatment of HER2-expressing solid tumors, including breast and gastric cancers.
CSPC Pharmaceutical Group Ltd. has received clearance from China’s National Medical Products Administration (NMPA) to conduct clinical trials of antibody-drug conjugates (ADCs) SYS-6005 and SYS-6043.
Iomx Therapeutics AG has submitted a clinical trial application (CTA) for IOMX‑0675, a dual‑targeting, fully human antibody designed to address the key immune-regulatory LILR receptor family expressed on myeloid and lymphoid immune cells.
Inceptor Bio LLC and Shenzhen Grit Biotechnology Co. Ltd. have established a strategic partnership to advance IB-T101, a CAR T therapy targeting solid tumors.
Tigatx Inc. has been awarded up to $33.5 million in funding by the Advanced Research Projects Agency for Health and a 2-year $2 million Direct to Phase II Small Business Innovation Research grant from the National Cancer Institute.
B7H3 is a pan-cancer antigen considered a promising target for immunotherapy. However, targeting B7H3 using bispecific T-cell engagers (BiTEs) presents the problem of systemic toxicity.
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.
