In effect, a small clinical trial made at Memorial Sloane Kettering Cancer Center in New York gave impressive results: 100% of patients were in remissionwithout the need for surgery or chemotherapy, after treatment with a Structure of an antibody

In 100% of patients, the tumor was undetectable at scannerMRI,endoscopy and in biopsies rectal. They did not need surgery or chemotherapy to complete the action of dostarlimab. No patient had a relapse during the follow-up period, which lasted from 6 to 25 months. Dostarlimab did not cause serious side effects in most patients, only rashes, fatigue, nausea, and nausea.

Only one person developed a non-life-threatening thyroid problem.
Dostarlimab also offers hope for people with syndrome of Lynch – eight among the twelve participants in theclinical test. This hereditary disease drastically increases the risk of developing cancer colorectal disease throughout life, and is associated with poorer outcomes after surgery or cancer chemotherapy. L’immunotherapy could be a promising tool to treat patients affected by Lynch syndrome.

Dostarlimab is an antibody that prevents recognition of the PD-1 receptor, located on the lymphocytes T, with sound ligand PDL-1, located on cancer cells. The interaction of the receptor with its ligand paralyzes the immune response – instead of destroying the abnormal cell, the T lymphocyte spares it. By mechanically blocking this interaction, dostarlimab allows T cells to destroy the abnormal cell.
Impressive results that will need to be replicated in future independent clinical trials involving more participants. The question of the sustainability results will also be crucial; if the participants have been in remission for several months, there is nothing to say to date that they will still be in several years.
