AstraZeneca's tozorakimab drug for chronic obstructive pulmonary disease also seems underappreciated, with a potential to reach $4.5 billion in peak sales, according to Jefferies. The firm also suggests up to $3.5 billion in sales for AstraZeneca's eplontersen , a drug aimed at treating hereditary transthyretin-mediated amyloid polyneuropathy. The pharmaceutical giant is also poised to be the frontrunner in breast cancer treatments. Another one of AstraZeneca's breast cancer therapies, also being developed with Daiichi Sankyo, came out with positive news Friday. Its experimental precision drug datopotamab deruxtecan demonstrated an improvement in slowing the progression of a common type of breast cancer in a late-stage trial.
