A bit of history

Stanley Crooke founded Isis Pharmaceuticals in Carlsbad in 1989 to develop antisense therapy, a bet that took decades to pay off before Biogen partnership SPINRAZA won approval in 2016 and validated the whole platform; the company renamed itself Ionis Pharmaceuticals in 2015. That early antisense research base helped establish Carlsbad and the rest of San Diego's North County as a life-sciences cluster in its own right, distinct from but connected to San Diego's broader biotech scene to the south.
