Suboxone decision puts pressure on Indivior follow-up products


Dr Reddy’s launch of a generic version of Suboxone more than a year earlier than expected caused Indivior’s shares to crash 47% yesterday, and now the US speciality pharma group will need its follow-on opioid addiction treatment Sublocade to meet expectations. This is because a federal court yesterday vacated an injunction imposed on Dr Reddy’s in July when it had tried to launch, and this decision should allow the Indian company to begin shipping its version of the buprenorphine and naloxone sublingual film in December. This came 12-18 months earlier than expected, as Indivior’s intellectual property estate was expected to be strong enough to keep the injunction in place. Stifel analyst Max Herrmann said the decision should reduce Suboxone 2019 sales by 80%. EvaluatePharma’s sellside consensus data currently forecasts $533m in 2019. Sublocade, an extended-release buprenorphine injection, will not achieve similar sales until 2021, according to consensus.
