Pricing of the treatment for Non-Muscle Invasive Bladder Caner (NMIBC)
The price of cancer treatment tends to be very expensive for general public. Keytruda is PD-1 immune checkpoint inhibitor which is used as immunotherapy. It has been used to treat advanced bladder cancer and for NMIBC, it had been approved to treat BCG Unresponsive patients. The list price of Keytruda for one treatment is $10,474.08 when given every 3 weeks according to MERCK Keytruda site. That means the annual cost will be about $180K for a patient. Though MERCK provides complicated discount schemes to reduce the price, how can MERCK justify charging such high price? Why not $10K per year instead of $180K? Or, why not $500K? In principle, in the US, the price of the drug is not regulated. There was a study done in this matter for 10 cancer drugs approved by FDA. The median cost of developing a single cancer drug was $650 million. The median revenue after approval for such a drug was $1,658 million. The clinical trial for all cancer drugs between 2015-2017 was $32 million – median cost, with some large clinical trial costs over $100 million. Only 4% of cancer drug related clinical trials succeed. So, it kind of makes sense that cancer drugs are priced high.
Actually, there happens to be an organization which determines what is the justifiable price based upon various factors. The Boston based independent non profit organization is called The Institute for Clinical and Economic Review (ICER). ICER uses a formula based on quality-adjusted life years (QALYs), which generates an estimated dollar benefit for a drug, and then compares this number to the drug’s actual list price.
There are two FDA approved drugs for BCG Unresponsive NMIBC. One is VALSTAR® (valrubicin) which was approved in 1981. The other one is Keytruda (R) (pembrolizumab). There are two new drugs pending upon the approval of FDA. One is nadofaragene firadenovec by Fergene and the other drug is Vicinium ( oportuzumab monatox) by Sesen Bio. Sesen bio Vicinium was rejected at the end of Phase III and needs to require additional tests to meet FDA requirement.
ICER analyzed both drugs and came to its pricing as follows.
nadofaragene firadenovec 158,600-$262,000 per year Intravesical
Vicinium (R) ( oportuzumab monatox) $93,000-$162,000 per year IntravesicalThe performance data which ICER used is as follows.
