SYS6043 is a new type of antibody-drug conjugate, or ADC. It zeroes in on B7-H3, a protein that is expresse by advanced tumors but almost not at all on healthy cells. The antibody part sticks to B7-H3, gets pulled inside the cancer cell, and releases a topoisomerase I inhibitor that breaks the cell’s DNA and […]
A new immunotherapy called GTB-5550 targeting B7-H3 on cancer cells has received FDA clearance for its first human trial (expected to start in the first half of 2026), offering fresh hope particularly for advanced prostate cancer patients exhausted by standard treatments. GTB-5550 is a TriKE molecule that binds natural killer (NK) cells from the immune […]
BNT324 (DB-1311) is rapidly emerging as one of the most promising new agents in metastatic castration-resistant prostate cancer (mCRPC), with a data package that is unusually strong for a first-in-class B7-H3–targeting antibody–drug conjugate and now compelling enough to justify a head‑to‑head Phase 3 trial against docetaxel. The reason it has attracted so much attention is […]
GSK5764227 represents a promising advancement in treating metastatic castration-resistant prostate cancer (mCRPC). This antibody-drug conjugate targets B7-H3, a protein overexpressed on prostate cancer cells, delivering a topoisomerase I inhibitor payload directly to tumors while minimizing damage to healthy tissues. Early data from broader solid tumor studies show the drug’s monotherapy potential, with objective response rates […]
ITC-6146RO is an experimental cancer drug belonging to the class of antibody–drug conjugates, or ADCs. It received IND Approval from Korean Ministry of Food and Drug Safety (Following U.S. FDA) to start a first‑in‑human Phase 1 trial in people with advanced or metastatic solid tumors who no longer respond to standard therapies. It has been […]
We have already talked about it here, GenSci143, is a novel bispecific antibody-drug conjugate targeting B7-H3 and PSMA, and a phase 1 trial is set to begin first-in-human clinical trials soon (est. date December 20) in participants with advanced solid tumors, including metastatic castration-resistant prostate cancer. Recent regulatory approvals were granted by the U.S. FDA […]
GTB-5550, a novel tri-specific natural killer (NK) cell engager drug designed to target the B7-H3 antigen has shown notable promise in advancing cancer immunotherapy for solid tumors, particularly prostate cancer and head and neck squamous cell carcinoma (HNSCC). This drug functions by simultaneously binding to CD16 on NK cells, engaging B7-H3 expressed on tumor cells, […]
This Phase II study investigates the efficacy and safety of three investigational agents: SHR3680 (rezvilutamide), HS-20093, and SHR2554, aiming to enhance outcomes in metastatic prostate cancer through dual-pathway inhibition. SHR3680, a selective androgen receptor (AR) antagonist, represents the latest generation of hormonal therapy designed to inhibit the AR signaling axis, a critical driver of prostate […]
GenSci143 (aka GenSci-143) is a bispecific antibody-drug conjugate under development for metastatic castration-resistant prostate cancer (mCRPC) and other solid tumors. The construct targets B7-H3 (CD276) and PSMA simultaneously with a bispecific antibody, coupled via a stable, cleavable linker to a topoisomerase I inhibitor payload, aiming to improve tumor cell killing and bystander effects across heterogeneous […]
