Here are summaries of several recent failures in cancer drug trials

June 25 (Reuters) - AstraZeneca's blockbuster cancer drug Imfinzi has failed as a follow-up therapy to improve disease-free survival in a late-stage trial in patients with a type of early-stage lung cancer, the group said on Tuesday.
Imfinzi is a human monoclonal antibody, which works to block a tumor's ability to evade and dampen the immune system, while also boosting the body's anti-cancer immune response, offering an alternative to chemotherapy.

June 24 (Reuters) - G1 Therapeutics said on Monday its drug for a rare, aggressive form of breast cancer did not meet the main goal of overall survival in a late-stage trial.

G1's drug trilaciclib was tested in 187 patients with metastatic triple-negative breast cancer, with the patients who took the drug showing a median overall survival of 17.4 months, while patients who did not receive the treatment survived for 17.8 months overall.

FRANKFURT, June 25 (Reuters) - Shares in Germany's Merck KGaA slumped 8.9% at the open on Tuesday after the diversified group late on Monday said a trial testing a head and neck cancer drug, previously seen as promising, would be stopped for lack of efficacy.

The failure of drug candidate xevinapant is the latest in a string of high-profile development setbacks, shifting the focus to the group's two other divisions, making specialty chemicals for the electronics industry as well as lab gear and supplies for the biotech sector.
