A Phase I Study of CX5461

Summary

CX5461 is a new type of drug for many types of cancer, particularly cancers that cannot easily repair damage to their cells. This may help to slow down the growth of cancer or may cause cancer cells to die. CX5461 has been shown to shrink tumours in animals and has been studied in a few people and seems promising but it is not clear if it can offer better results than standard treatment.
