Claris Lifesciences has "received the EIR for its manufacturing facility located near Ahmedabad, wherein the US Food and Drug Administration (USFDA) has concluded that the inspection stands closed and the facility was found to be acceptable," Claris Lifesciences said in a filing to BSE today.
"The company had taken appropriate steps to address the observations it had received from these audits," Claris said.
Having received the EIR from the USFDA potentially clears the path for the company to receive product approvals (ANDA) for the USA, it added.
