Will Aimovig be covered by public drug plans in Canada?
We have been following the arrival of CGRP antibodies (Aimovig, Emgality) in Canada.
Below are a few comments on access and coverage.
What is the drug coverage system like in Canada?
Canadians pay their medications either through private insurance companies (with plans often linked with their work), public insurance systems or out-of-pocket (no insurance).
Estimates state that 60% of Canadians have private coverage, 30% public and 10% out of pocket. This varies depending on the province.
Private plans vary a lot, even with the same company between different people.
Are private payers covering for CGRP antibodies?
At present time, some private payers will reimburse CGRP MABs, often not 100%. Many will cover 80%. If one dose costs 540$, that would leave 108$ per month to be paid by the person. Patient Support Programs (PSPs) offered by the companies (Novartis, Eli Lilly) may be able to pay this cost for a while. This partial support is called a co-pay.
** If you are paying more than 540$ per dose of Aimovig or more than 625$ per dose of Emgality, it is because there are additional fees, for example pharmacy fees. This is a different question to be addressed later.
Are provincial public payers covering CGRP antibodies?
Not at present time. Public payers are waiting for the recommendation of CADTH, a public institution that assesses the value of medications. Health Canada’s job is to check that medications are safe and are effective. CADTH check if they are cost-effective, meaning are they worth paying for from a public health care perspective.

How can CADTH decide if a medication should be covered?
The final decision is from the provincial governments. CADTH makes a recommendation. This is a very serious process done by teams of experts. The input of patients is welcome. Migraine Canada did submit a report on erenumab and detailed what it means to live with migraine (thanks to everyone who participated to our survey). The team looks at the expected results of the drug, the disability and costs linked to the disease, and then sees if the drug has a real value for people and society.

When will the decision be made public?
According to the CADTH website, the decision could be made public in January. Other countries with national PharmaCare type systems (UK and Australia) have already decided not to cover Aimovig.

What would it mean if the decision is made not to recommend Aimovig?
It would mean that the Health Ministries of the provinces (excluding Quebec, that has its own drug assessment authority called INESSS) would probably decide not to cover Aimovig. Canadians living with migraine and having a public coverage would then have to pay out-of-pocket for the drug or subscribe to an additional private plan.
CGRP MABs like Aimovig seem effective for some people. Why would they not be covered?
That is a question of value for money. Migraine is a stigmatized disease. Its impact on life is often underestimated. Its cost on society is also underestimated. There is research on this. The value of the treatment could be difficult to fully appreciate. Also, migraine is very frequent (1/10 at least), and the burden on the public system would be bigger than for a rare disease like multiple sclerosis (1/1000).
Would there be other consequences of this decision?
Yes. Here are some things that could happen:
- This decision sends a strong signal about the evaluation of the whole CGRP antibody class. Other antibodies (Emgality, Ajovy) could be evaluated in a similar way as the results from the studies and the costs are quite similar.
- The public decision may influence private payers who are currently covering Aimovig. They could decide to decrease their coverage.
- Some patients are currently receiving financial support from Patient Support Programs (PSPs) from Novartis and Eli Lilly. This support is provided in waiting for a long-term coverage. If public plans decide not to cover, it may be that PSPs decide not to support people with public plans (this is only a hypothesis of course).
Would Aimovig be covered for everyone with migraine if the decision was positive?
No. Criteria for coverage would probably be >8 days per month with a migraine, and at least 2 previous failures with traditional oral preventives (amitriptyline, beta-blockers, topiramate etc.) That’s probably fair as the CGRP MABs are expensive and traditional options may work for a good number of people.
What can I do if I want to take action and tell the government and authorities that migraine is a serious disease and that treatments should be accessible?
At present time, CADTH is evaluating the data.
We have investigated the possibility of an online petition to send to the Health Ministries of different provinces. CADTH is funded by the provinces, so advocating to the provincial government could make sense. An online check found that governments do not accept e-petitions. We still have a lot to learn about advocacy in migraine and headache world. Considering that there was no national association until 2018, we are making progress!
Questions and comments:
Hi. Just checking to see how the approval process for Aimovig is progressing. I have been on it for a trial period, and after the first 3 months it really started to work well. I now am down to 1 mild migraine requiring a dose of Zomig per month. Its been especially good these last few months since the weather has been so variable and that is a big factor in my migraines. I have had them since I was a child and it does run in the family. Since I am down to one more dose, I am afraid to return to the old normal. I see my neurologist next month and I’m hoping to get on another CGRP trial. Our private drug plan, Great West, will not cover this medication yet since to them it is only a quality of life issue, and provinces haven’t picked it up yet. Hopefully the government will see that this works for many migraineurs and adds it. Thanks for your efforts and fingers crossed that approvals will come sooner than later.
Was on Go Program now it’s finished. Same problem, Same boat, no coverage. I have saved doses. Feel like chatting about what to do please contact me : Katie SparkleandBespoke@gmail.com
I’ve been on the trial plan for Aimovig for about 6 months now and it’s turned my life around completely. I went from having a chronic migraine almost every single day to 3 or 4 a month (which I ease by taking a triptan). I received the email stating the trial was ending regardless of how many refills were issued to the client and I am devastated as my husband and I have no insurance. We looked into single insurance plans and many of them were going to be well over $300 a month while only providing a total coverage of $1000 a year for prescription medication. At the present cost of each Aimovig injection, this wouldn’t even cover two months worth. I’m extremely disappointed about losing access to the one medication that has worked in treating my chronic migraines and now I must anticipate going back to take 20+ triptans a month, enduring a chronic migraine almost every day once again. The cost of medication is beyond outrageous.
Hi Natasha. It certainly sucks. We have finally found something that works but the cost is prohibitive. Ugh. Covid will make things worse since governments are now going into huge budget deficits to fight the virus. Migraines are off the radar now. My neuro is hoping Aimovig has given my brain a reset. I hope so, I’ve been having migraines since I was a kid. Good luck to you.
