A new experimental cancer drug called GRWD5769 has shown good results in a recent global medical trial, scientists reported at a conference in Chicago. GRWD5769 was tested on 83 patients with six different types of advanced cancer after other treatments had failed.

The drug works by blocking a specific enzyme in cancer cells, which helps the body's immune system find and attack the tumours. In the study, doctors gave GRWD5769 together with another immunotherapy medicine called cemiplimab.

Researchers observed that tumours got smaller in 26 patients, and 15 of them had a reduction of at least 30%. Larger studies are now planned to confirm if the treatment is effective and safe for more people in the future.
