Last month, a dozen advocacy groups began an e-mail petition to convince drugmakers to disclose their contributions. Now, they’ve written to each ceo, along with Phrma and the International Federation of Pharmaceutical Manufacturers Associations, to make a direct appeal.

Once again, their effort cites Lilly’s recent decision to do so, at least in the US, and so the groups - which now number nearly 40 and include Public Citizen and the Center for Science in the Public Interest - implore all drugmakers to follow suit, and to do so on a global basis. The reason? Their concern that donations result in off-label marketing by groups receiving funds; mask the agendas of public policy groups that debate policy issues, and allow researchers to circumvent normal dislcosure requirements.

We’ll let you know if anyone responds. Meanwhile, to see the letter and the complete list of advocacy groups, you can visit PharmaDisclose.
