Dr Reddy’s s Laboratories Ltd is seeking more than $70 million from Indivior Plc as compensation for lost US sales of its generic version of a leading opioid addiction treatment that was delayed in a patent dispute with the UK-based drugmaker.

Indivior had managed to block Dr Reddy’s generic version of Suboxone Film through a court injunction in July, despite the Indian company receiving regulatory approval earlier to sell the market-leading product for opioid dependence. Last month, the US Supreme Court refused to uphold that injunction, allowing Dr Reddy’s s to resume sales of the drug.

“If we were not injuncted by the court, we would have made a lot of money,” GV Prasad, Dr Reddy’s MD and CEO, said in an interview in Hyderabad. “If we get the lost profits, it will certainly outperform.”

Suboxone is the leading prescription drug used to treat opioid abuse in the US, which is battling an addiction crisis that the Centers for Disease Control and Prevention estimates kills 130 Americans every day. Suboxone Film — absorbed by being placed under the tongue or inside the cheek to treat addiction to opioids, including heroin and prescription painkillers — accounted for almost all of Indivior’s $1 billion in sales last year.

Indivior posted a bond of $72 million to cover Dr Reddy’s s potential claim of lost profit while the injunction was contested, according to Prasad. Dr Reddy’s is claiming that it is owed more than that since the injunction lasted longer than the bond was meant to cover. He declined to say how much the company is asking for.

Notwithstanding legal costs and the three other generic versions of Suboxone Film which have entered the US since Dr Reddy’s legal victory, Prasad estimated his company could still get about a quarter of the market share, making it a profitable product.
