Shanghai Henlius Biotech Inc.’s HLX-3902, a trispecific antibody targeting STEAP1xCD3xCD28, has received approval from the Human Research Ethics Committee (HREC) in Australia and has been filed with the Therapeutic Goods Administration (TGA). The T-cell engager is intended for the treatment of metastatic castration-resistant prostate cancer and other advanced solid tumors.
Resistance to microtubule-targeting agents such as taxanes and vinca alkaloids is often driven by drug efflux and changes in tubulin behavior. Targeting the colchicine-binding site provides an alternative strategy that may circumvent these resistance mechanisms.
Researchers from Flare Therapeutics Inc. presented the preclinical profile of FX-111, a selective active androgen receptor (ARON) degrader, in models of prostate cancer.
T-cell engagers (TCEs) drive synthetic antitumor immunity by bypassing endogenous T-cell priming and directly inducing tumor cell killing. In prostate cancer, targeting prostate-restricted antigens such as STEAP2, combined with CD8-guided TCE formats that favor cytotoxic T-cell engagement, offers a strategy to reduce cytokine release while maintaining antitumor activity.
After a hiatus of more than nine months, the U.S. FDA’s Oncologic Drugs Advisory Committee (ODAC) will meet April 30 to discuss two Astrazeneca plc applications – an NDA for camizestrant used in combination with a CDK4/6 inhibitor to treat HR+HER2- locally advanced or metastatic breast cancer and an sNDA for Truqap (capivasertib) to treat metastatic hormone-sensitive prostate cancer that’s phosphatase and tensin homolog deficient.
U.S. researchers have published data regarding IVMT-Rx-4, a melanoma differentiation-associated gene-9 (MDA-9) inhibitor with potential to treat bone-metastatic prostate cancer.
Retinoid X receptor γ (RXRγ) is a key nuclear receptor that sustains androgen receptor (AR) signaling. In castration-resistant prostate cancer (CRPC), RXRγ contributes to disease progression by maintaining adaptive transcriptional networks that promote therapy resistance and tumor cell survival.
Liver receptor homolog-1 (LRH-1) is a nuclear receptor that promotes the transcription of genes encoding key steroidogenic enzymes, thereby facilitating de novo androgen biosynthesis within the prostate tumor microenvironment. Researchers from Qilu Pharmaceutical Co. Ltd. reported the discovery and preclinical characterization of a series of novel LRH-1 antagonists.
Ocean University of China has discovered new androgen receptor N-terminal domain (AR-NTD) inhibitors reported to be useful for the treatment of prostate cancer.
Aktis Oncology Inc. has obtained IND approvals from the FDA enabling the company to proceed to a phase Ib trial with AKY-2519, a miniprotein radioconjugate targeting B7-H3-expressing tumors, including prostate, lung and other solid tumors. Specifically, the IND clearances relate to [64Cu]Cu-AKY-2519 for imaging and [225Ac]Ac-AKY-2519 for therapeutic use.
