Request for information - Hepatitis C treatments

Medicines Consultation Closed

PHARMAC is seeking information from suppliers of novel direct-acting antiviral agents (DAAs) for the treatment of hepatitis C.

This Request for Information (RFI) also seeks information from clinicians, hepatitis C healthcare professionals, others who provide support for people with hepatitis C, and those people who are affected by hepatitis C on the services that are provided for people with hepatitis C and the resourcing required for these services.

Examples of the classes of DAAs that PHARMAC is particularly interested in include:

  • non-structural protein (NS) 3/4A protease inhibitors
  • NS5A inhibitors
  • NS5B nucleoside polymerase inhibitors
  • NS5B non-nucleoside polymerase inhibitors.

PHARMAC welcomes information relating to other classes of agents available or in development to treat hepatitis C, including but not limited to cyclophilin inhibitors.

PHARMAC is particularly interested in receiving information in relation to those agents, including those in phase II & phase III clinical trials that do not need to be used in combination with pegylated interferon.

Information provided will help inform and assist PHARMAC in determining the most appropriate approach to assessing and making decisions about funding for novel DAAs.

If you wish to submit a response to the RFI, you must submit it to PHARMAC by email no later than 9am on 21 September 2015.

Submissions and any questions you might have can be sent to hepc@pharmac.govt.nz.

Background

Purpose

This RFI seeks information to inform and assist PHARMAC in determining the most appropriate approach to assessing and making decisions about funding for novel DAAs for hepatitis C.

Suppliers of DAAs

PHARMAC wishes to gauge the level of interest from suppliers of DAAs in relation to potential future supply arrangements for DAAs, and obtain information on suppliers’ range of DAAs. This information should include Medsafe-registered agents, agents that are registered overseas but not yet registered with Medsafe, and agents in development.

People who treat or support those with hepatitis C or who are otherwise affected by hepatitis C

PHARMAC also seeks input from clinicians, hepatitis C healthcare professionals, others who provide support for people with hepatitis C and those people who are affected by hepatitis C.

We are interested in information relating to the services that are available for people diagnosed with hepatitis C, how many people are accessing these services and the resourcing that is required for them (for example, but not limited to staff, capital, equipment costs). We are also interested in how these services might be affected if novel DAAs for hepatitis C were funded.

We note the estimates from Gane et al.[1] that there are currently approximately 20,000 people in New Zealand who are diagnosed with hepatitis C. In addition, there is estimated to be 30,000 people within New Zealand who are infected with the hepatitis C virus but are currently undiagnosed. PHARMAC welcomes the views of people involved in the treatment or support of people with hepatitis C on the implications of a potential increase in patient numbers on the services that they provide, both if treatment regimens remain as they currently are and if novel DAAs for hepatitis C were funded.

This information will help us to understand the wider implications and impacts that any decision that we may make will have on these services.

Outcome following close of RFI

We note that following this RFI PHARMAC would continue with its normal consideration process for funding applications it has received for hepatitis C DAAs, including analysis and ranking against other funding opportunities and funding from within the available budget.

PHARMAC could, following assessment of information received in response to this RFI, (at its discretion):

  • commence negotiations with one or more specific supplier(s)
  • undertake a competitive process for one or more DAAs
  • decide not to progress the funding of novel DAAs at this time.

PHARMAC may also seek further advice before deciding upon its next steps, depending on the information received.

The progress of these applications can be followed, including access to minutes of advisory committee reviews where these have occurred, by typing the treatment name into PHARMAC’s application tracker which can be found at:

 https://www.pharmac.govt.nz/ApplicationTracker

The applications for sofosbuvir (Sovaldi) and ledipasvir with sofosbuvir (Harvoni) have undergone review by PHARMAC’s clinical advisory committees, including review by the Pharmacology and Therapeutics Advisory Committee (PTAC). PTAC identified various subpopulations of people with hepatitis C infection and made its recommendations for funding according to these groups. The most recent review of these applications was by PTAC at its May 2015 meeting. Full minutes of the May 2015 PTAC meeting can be found on the PHARMAC website (2015-15 minutes, published 14 July 2015).

In summary, PTAC recommended:

Sofosbuvir

The Committee recommended that sofosbuvir should be funded with a high priority for the following subpopulations:

  • HCV patients with decompensated cirrhosis (all genotypes[2])
  • HCV patients pre/post liver transplant (all genotypes)
  • HCV patients, genotype 1, 2 and 3, with essential mixed cryoglobulinaemia (with associated purpuric skin rash, cryoglobulinaemic glomerulonephritis and systemic vasculitis),

The Committee recommended that sofosbuvir should be funded for all other subpopulations with a low priority.

Ledipasvir with sofosbuvir

The Committee recommended that ledipasvir with sofosbuvir should be funded with a high priority for the following subpopulations:

  • HCV patients with decompensated cirrhosis (all genotypes)
  • HCV patients pre/post liver transplant (all genotypes)
  • HCV patients with essential mixed cryoglobulinaemia (with associated purpuric skin rash, cryoglobulinaemic glomerulonephritis and systemic vasculitis).

The Committee recommended that ledipasvir with sofosbuvir should be funded for all other subpopulations of patients with chronic hepatitis C with a low priority based solely on fiscal risk.

The applications for paritaprevir/ritonavir, ombitasvir, dasabuvir (Viekira Pak) and simeprevir (Olysio) have not yet undergone review by PHARMAC’s clinical advisory committees.
