Apropos to cGMP issues, Teva received an FDA warning letter regarding its manufacturing practices at its Jerusalem manufacturing facility, which was inspected in September.
Found out why Teva couldn't manufacture on their own - a cGMP issue with its Irvine, CA facility. They had to partner so they can at least enjoy some of the exclusivity period.
Moreover, since asking the question in #msg-59214635, I learned that Abraxis BioScience (APP Pharma’s ancestor) had done contract work for LLY on Gemzar.
