Cabazitaxel in Combination With 177Lu-PSMA-617 in Metastatic Castration-resistant Prostate Cancer

Cabazitaxel belongs to the Taxane group of drugs which function by interfering with microtubule depolymerisation and thus inhibit mitosis, which leads to cell death via apoptosis. It is the first chemotherapy agent to improve survival in patients with mCRPC with progressive disease after docetaxel-based treatment.

Lutetium-177 (177Lu)-PSMA is a radiopharmaceutical comprised of a small molecule inhibitor of PSMA that binds with high affinity to PSMA which is expressed on the prostate cancer cell, labelled with 177Lu. 177Lu has favourable characteristics for radionuclide therapy emitting both a short-range (1-2mm) cytotoxic beta-particle, minimising irradiation of non-targeted normal tissues, alongside gamma emission that allows imaging. Multiple clinical trials have demonstrated high clinical activity and limited normal tissue toxicity using 177Lu-PSMA-617.
