April 23 (Reuters) - AbbVie ‌said on Thursday the ‌U.S. Food and Drug Administration has declined to approve its experimental wrinkle treatment, trenibotE, citing issues in ​manufacturing.

Here are some details:

• TrenibotE is a type of botulinum toxin designed to treat facial wrinkles ⁠such as frown lines. It starts to show effect as early as eight ​hours after administration and lasts for two to three weeks.

• The setback removes a near-term ​catalyst for AbbVie’s aesthetics business, ‌but Street expectations for trenibotE were modest, Citi analyst Geoff Meacham said.

• Meacham also ⁠noted that manufacturing‑related requests have likely delayed approval into 2027.

• AbbVie added the agency did not raise concerns about ⁠the treatment's safety or efficacy, and did not ask for new ​patient studies.

• The company dominates the aesthetics market, generating multi-billion-dollar revenues from its Botox treatment, which are used for wrinkle smoothing, ‌migraines and muscle disorders.

• The company said trenibotE has been studied in more than ‌2,100 patients, including two late-stage trials and a safety ⁠study.

• AbbVie said regulatory ‌reviews of the ​treatment in other countries are still underway.
