May 22 (Reuters) – A European Medicines Agency committee on Friday backed approval for AstraZeneca’s experimental breast cancer pill, camizestrant, differing from a U.S. regulatory ​panel’s opinion about the drug.

The positive opinion comes weeks ‌after a panel of advisers to the U.S. Food and Drug Administration voted against the treatment, raising concerns about the design of a key late-stage trial rather than the treatment’s safety or effectiveness.

Friday’s decision paves the way ‌for ​approval from the European Commission to ⁠use the drug in combination ⁠with another type of therapy known as CDK4/6 inhibitor.

Camizestrant is among the 20 new medicines that the Anglo-Swedish drugmaker expects to launch by 2030 to hit its $80 billion revenue target. ​It expects the drug will contribute more than $5 billion in peak annual sales.

Susan Galbraith, a senior executive at AstraZeneca, said ⁠that the recommendation was “an important first ⁠step” and the company will work with different ​countries for access after approval.

EMA’s recommendation is based on a late-stage ​study in which the drug, in combination with other ‌cancer medicines, reduced the risk of cancer progression or death by 56%.

The combination helped keep the disease under control for about 16 months on average, compared with just over nine months with ⁠standard treatment.

Expert advisors to the FDA had largely expressed concerns about the trial design. The FDA typically follows the advice of its experts ⁠but is not bound ‌to do so.

“We’re really pleased to see ⁠that the CHMP (Committee for Medicinal Products for Human ​Use) ‌has recognized the value of this monitoring approach,” ​said Galbraith.

She ⁠said discussions were ongoing with regulatory authorities in the U.S. and the company will present additional data from the trial at a medical conference at the end of this month.
