Description

Dranitsaris et al reported a value-based pricing index (VBPI) for a new drug to treat metastatic colorectal carcinoma. This can be used to price a drug in different countries based on the ability to pay. The authors are from Nelson Mandela Metropolitan University and North-West University in South Africa.


 

Parameters:

(1) base price in dollars ($11,000)

(2) Gini coefficient for the country

(3) country specific per capita GDP

(4) survival benefit in months

 

price to use in the county =

= ((base cost in dollars) + (300 * (Gini)) - (per capita GDP) - (6000 * (months of survival benefit))) * (-0.05)

 

This can be rewritten as

 

price to use in the county =

= (0.05 * (GDP)) + (300 * (months survival benefit)) - (15 * (Gini)) - (0.05 * (base cost))

 

This version can be revised to the coefficients in Table 3:

 

price to use in the county =

= (0.051 * (GDP)) + (296 * (months survival benefit)) - (15.1 * (Gini)) - 542

 

where:

• 542 is 0.05 times 11000

 

Limitations:

• This is based on the concept of "ability to pay".
