In August 2015, the price of Daraprim in the US rose from $US13.50 per tablet to $US750 when Turing Pharmaceuticals, and its controversial then-chief executive Martin Shkreli, acquired the drug's exclusive rights and hiked up the price.
Since then, the 17-year-olds from Sydney Grammar have worked in their school laboratory to create the drug cheaply in order to draw attention to its inflated price overseas, which student Milan Leonard said was "ridiculous".
"It makes sense that if you're putting billions of dollars into research for a drug like this, you should be able to reap some profit, but to do something like this … it's just not just," he said.
Milan described the moment he realised he and his classmates had been successful.
"It was ecstatic, it was bliss, it was euphoric," he said.
"After all of this time spent working and chemistry being such a high and low, after all the lows, after all the downs, being able to make this drug, it was pure bliss."
Fellow student Brandon Lee said he could not believe the result after a year of work.
"At first there was definitely disbelief," he said.
"We spent so long and there were so many obstacles that we, not lost hope, but it surprised us like 'oh, we actually made this material' and 'this can actually help people out there'.
"So it was definitely disbelief but then it turned in to happiness as we realised we finally got to our main goal
