SHANGHAI, March ‌6 (Reuters) - China ​has ​approved Pfizer's GLP-1 treatment Xianweiying for long-term weight management in overweight or obese adults, the U.S. ‌drugmaker said on WeChat on Friday, boosting competition in ⁠a market analysts expect to be worth billions of dollars.

The injection ‌belongs to the class ‌of GLP-1 receptor agonist drugs sold locally by drugmakers such as Novo Nordisk, Eli Lilly, and Innovent Biologics.

"This marks ​a breakthrough in the field of weight management," Pfizer's licensing partner Sciwind Biosciences said on its website.

In February, ⁠Pfizer licensed the mainland China commercialisation rights for Xianweiying, also known as ecnoglutide, ​from Sciwind, based in the eastern city of Hangzhou.

That deal was "an important first step to advance Pfizer's ​global strategy in the metabolic field ‌in China", Sciwind said in a previous statement.

Sales of Novo's Wegovy on Alibaba’s Tmall e-commerce ⁠platform and JD.com were 260 million yuan ($38 million) in 2025, against 416 million ($61 million) for Innovent's Xinermei, investment bank Jefferies said in ⁠a note.

The approval in China for long-term weight management props up ​Pfizer's footing in the booming weight-loss drug market.

It has also recently acquired the obesity drug developer Metsera, as well as another experimental GLP-1 ‌drug from another developer.

A Pfizer spokesperson said in a statement to Reuters that Xianweiying was ‌a once-a-week injection. They declined to comment about pricing and a ⁠China launch date.

Ecnoglutide is ‌also approved in ​China as a treatment for Type 2I diabetes.
