Request for information: Preventing bias when considering medicines for funding
Thank you for your request dated 9 December 2021 under the Official Information Act 1982 
(OIA) for questions relating to assessment bias towards new medicines, particularly 
regarding the new Pfizer antiviral medicine and ivermectin. You wrote:
What systems are in place to ensure that Pharmac doesn't suffer from confirmation bias, 
group think or a preference towards new medications vs existing licensed expired 
medicines that aren't supported for an application, due to them being inexpensive.

For example it appears that Pharmac rely on an application for approval of medicines for 
a different, and if a medicine is out of patient a private pharmaceutical company would 
have a much larger incentive to make a new drug than prove the efficacy of a preexisting 
in-expense drug. And as such would not put in an application or do additional research to 
make the case for it. The pharmaceutical companies would also have a direct incentive to 
actively discredit or promulgate mistrust of studies that weren't to their financial interests 
and create a public narrative to support that.

Can New Zealanders have confidence that large pharmaceutical companies which 
sponsor and fund a significant amount of US media have not deliberately promulgated a 
narrative of mistrust around the drug Ivermectin. As this looks like it would be financially 
ruinous to its new Pfizer antiviral, PF-07321332, can New Zealand have confidence that 
the US media and its media narrative that the drug is just a 'horse medicine' or only for 
the treatment of parasites has not negatively influenced its assessment as a useful drug 
in combating Covid-19.

And is our application based system fit for purpose, or does it relies too much on private 
companies initiating the process. How much do our Pharmac assessors and the Ministry 
rely on just maintaining a status quo based on overseas decisions where their 
assessments and scientific assessments may not be completely impartial?

The new Pfizer antiviral, PF-07321332 appears to have the same function as a protease 
as Ivermectin but as Ivermectin is out of patient and significantly cheaper this could be 
significantly more adventitious. Has an updated assessment taken place on either of 
these drugs and are they approved for use in the treatment of Covid-19?

The information in the below video is gathering more attention:

In it Dr. John Campbell appears to be making some compelling claims for the use of 
Ivermectin, has Pharmac and the Ministry of Health assessed the studies he has cited in 
relation to an assessment of Ivermectin?

How Pharmac works
Pharmac is the agency that decides which medicines are funded in New Zealand. Our 
statutory directive is to get the best health outcomes that are reasonably achievable from 
within the available funding. We also manage the fixed budget (Combined Pharmaceutical 
Budget) for those medicines. 
Medsafe is the authority responsible for evaluating and assessing therapeutic products for 
use in New Zealand. Generally, before a medicine is funded by Pharmac it needs to be 
approved by Medsafe.
