BioNTech’s licensed antibody-drug conjugate is moving on to Phase III testing in a potential effort to challenge AstraZeneca and Daiichi Sankyo’s blockbuster Enhertu in a heavily treated breast cancer subpopulation. DualityBio, BioNTech’s partner and the ADC’s creator, posted the trial plans Wednesday. 

AstraZeneca said on Monday a mid-stage trial of its cancer drug Enhertu showed positive results across multiple HER2-expressing advanced solid tumors in heavily pre-treated patients.

Gilead Sciences Inc. said on Friday the U.S. Food and Drug Administration had greenlighted expanded use of Trodelvy to treat the most common type of breast cancer, marking the third approval for the drug.

The rush to use AstraZeneca and Daiichi-Sankyo’s drug Enhertu to treat certain types of breast cancer has far outpaced doctors’ ability to determine with certainty which patients might benefit, experts said this week at a meeting of breast cancer doctors.

Spectrum Pharmaceuticals Inc. said on Friday the U.S. Food and Drug Administration (FDA) declined to approve its experimental lung cancer drug due to inadequate data, prompting the drugmaker to cut jobs.

The U.S. Food and Drug Administration’s (FDA) staff on Tuesday raised concerns over the safety of Spectrum Pharmaceutical’s experimental cancer drug and questioned the benefits it provided over existing therapies, dragging its shares 30%.

Gilead Sciences Inc.’s Trodelvy extended by 3.2 months the survival of patients with advanced stages of a common type of breast cancer, according to data released ahead of a presentation at a European cancer meeting on Friday.

Weeks after AstraZeneca and Daiichi Sankyo were able to move the bar in the treatment of metastatic breast cancer with Enhertu, Gilead Sciences is answering that challenge with Trodelvy.

AstraZeneca said a late-stage trial had confirmed the benefit of breast cancer drug Enhertu in patients with an advanced form of the disease who had been previously treated with another therapy.

As the biotech world awaits the announcement of Merck’s anticipated buyout of Seagen, an arbitrator came down on the side of Daiichi Sankyo in a patent battle against the Seattle-based biotech.
