The leak of new information on the Trans-Pacific Partnership agreement (TPP) shows the mega-trade deal could provide more ways for multinational corporations to influence Australia's control of its pharmaceutical regulations. Revealed via Wikileaks, the annexe on transparency and procedural fairness for pharmaceutical products and medical devices" uncovered the draft agreements regarding medicines between the 12 TPPA member countries [representing] 40% of the world's economy. The leaked text, dated December 2014, laid out the draft rules for member countries regarding medicines under national health care programs, in Australia's case, the Pharmaceutical Benefits Scheme (PBS). This 'transparency' annexe seeks to erode the processes and decisions of agencies that decide which medicines and medical devices to subsidise the public money and by how much. That will mean fewer medicines are subsidised, or people will pay more as co-payments. However, [trade minister Andrew] Robb said ... that the government would not accept anything that would adversely affect the PBS. Parliamentarians were offered the chance to see the TPP draft by Robb [only] if they agreed to a four year non-disclosure agreement. Senator Peter Whish-Wilson ... who has not seen the draft as he refused to agree to the terms of the agreement, said the latest leak suggested the Australian PBS could be undermined.
