NEW YORK, October 2 (Reuters) -Eli Lilly was asked to produce more insulin; Pfizer to produce more of its top-selling cancer drug Ibrance and its cholesterol drug Lipitor; and London-based AstraZeneca to consider a new headquarters in the U.S., according to two sources. Pharmaceutical executives are getting near-daily calls from staff at the White House – including Chief of Staff Susie Wiles – and senior figures at agencies like Health & Human Services and the Commerce Department, two sources familiar with the matter said. But pharmaceutical companies are the tip of the iceberg.
