Times have changed at Ionis Pharmaceuticals Inc. since it spun out Akcea Therapeutics Inc. in 2015. The company’s evolution is such that Ionis is now ready to bring Akcea back into the fold by acquiring the remaining 24% of its affiliate.

Akcea Therapeutics Inc., a majority owned affiliate of Ionis Pharmaceuticals Inc., and Pfizer Inc. signed an exclusive, worldwide licensing deal for AKCEA-ANGPTL-3-LRx, which is being developed to treat cardiovascular and metabolic diseases. The deal follows a period during which Akcea's stock (NASDAQ:AKCA) has sagged prior to rising Monday and big changes in the company's C-suite.
