Potential for drug substitution can threaten patients’ successful treatment
MONTREAL - February 5, 2015
The policy announced this week by the Quebec Ministry of Health regarding funding for a biologic arthritis drug raises questions for both patients and physicians, says The Arthritis Society.
Many Quebec residents are prescribed the biologic drug Remicade® (infliximab) to help manage severe pain and inflammation of rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. The arrival to market of a similar drug – Inflectra® – provides the province with a less expensive alternative (a difference of 31%, amounting to thousands of dollars for a typical patient).
“Access to more treatments – and to less expensive options – is good for all concerned,” explains Eric Amar, executive director of The Arthritis Society’s Quebec division, “but patients need certainty that a medication they are responding well to won’t be swapped out down the road in favour of a cheaper alternative.”
Inflectra is a subsequent entry biologic
, or SEB, produced by another manufacturer after the original biologic’s patent expires. Unlike typical generic drugs, however, biologics are so complex that SEBs cannot be considered exact duplicates. They are similar but not identical to the original drug, which is why in a recent position paper
The Society advocated against drug substitution for biologics.
“There is not enough information about the impact of switching from an innovator biologic to an SEB mid-treatment,” said Dr Frédéric Morin, rheumatologist and AMRQ president. “While SEBs may prove effective for newly-diagnosed patients, patients who are already responding well to an established course of treatment should only switch prescriptions out of medical necessity, not for financial reasons.”
The Arthritis Society has requested a meeting with Gaétan Barrette, Quebec’s health minister, to seek clarity on the government’s policy.
