A new class of drug successfully targets treatment-resistant prostate cancers and prolongs the life of patients. The treatment delivers beta radiation directly to tumour cells, is well tolerated by patients and keeps them alive for longer than standard care, found a phase 3 trial to be presented at the European Association of Urology congress, EAU21, today.
Despite progress in medicine in recent years, metastatic castration-resistant prostate cancer remains untreatable and fatal. The new treatment, known as Lu-PSMA-617, takes a new approach, targeting a molecule called PSMA, which is known to be increased on the surfaces of the tumour cells, destroying them and their surrounding microenvironment.

Ionizing radiation is used for treating nearly half of all cancer patients. Radiotherapy works by damaging the DNA of cancer cells, and cells sustaining so much DNA damage that they cannot sufficiently repair it will soon cease to replicate and die. It s an effective strategy overall, and radiotherapy is a common frontline cancer treatment option. Unfortunately, many cancers have subsets of cells that are able to survive initial radiotherapeutic regimens by developing mechanisms that are able to repair the DNA damage. This often results in resistance to further radiation as cancerous growth recurs. But until recently, little was known about exactly what happens in the genomes of cancer cells following radiotherapy.

Treatment increased hemoglobin, decreased fatigue
Results from a small open-label trial suggested that treatment with an investigational humanized monoclonal antibody may be an effective treatment for cold agglutinin disease, a rare autoimmune hemolytic anemia for which there are no approved therapies.
The 26-week, single-group trial tested intravenous sutimlimab in 24 cold agglutinin patients who had recently undergone transfusions and found infusions of the antibody halted hemolysis, increased hemoglobin levels, and reduced fatigue in more than half of patients.
The composite primary endpoint was a “normalization of hemoglobin level to 12 g or more per deciliter or an increase in hemoglobin level of 2 g or more per deciliter from baseline, without red-cell transfusion or medications prohibited by protocol,” Alexander Röth, MD, of the West German Cancer Center, University Hospital Essen, University of Duisburg-Essen in Essen, Germany, and colleagues reported.
