Marlborough-based pharmaceutical company Sumitomo Pharma America, a U.S. subsidiary of Japanese parent company Sumitomo Pharma, is set to lay off 53 employees, as the company continues to reduce its workforce.

The affected employees will be laid off on Sept. 30, according to a Worker Adjustment and Retraining Act notice filed to the MassHire Department of Career Services. 

The impacted employees work in the Aptiom department; Aptiom is a prescription medicine developed by Sumitomo used to treat partial-onset seizures.

Employees were notified of the layoffs in January, according to a filing sent to the state on Thursday. Nearly all of the employees work remotely outside of Massachusetts, but report to the Marlborough headquarters on 84 Waterford Drive.

The company saw recent layoffs affecting 400 U.S. employees as Sumitomo Pharma reduced its workforce to improve management and streamline operations in March 2024, according to a March 4 press release from Sumitomo Pharma.  

Sumitomo generated $1.64 billion between April 1, 2023, and Dec. 31, 2023, a decline from $3.22 billion during the same period in 2022, according to Sumitomo Pharma’s third quarter report ending March 31, 2024.

Former Marlborough-based Sunovion Pharmaceuticals combined with six of the seven U.S. subsidiaries of Japanese parent company Sumitomo Pharma to form Sumitomo Pharma America, headquartered in Marlborough in July 2023.  Over 200 workers were laid off as a result of the company’s restructuring in the U.S. in May 2023.
