Teva wins FDA OK for crucial migraine drug

Teva wins FDA OK for crucial migraine drug2018.09.19

Teva has secured US approval for migraine drug Ajovy, a key part of new chief execeutive Kåre Schultz's turnaround plan for the company.

The FDA approved the CGRP inhibitor for the prevention of migraine in adults with either monthly or quarterly dosing, based on two phase 3 studies showing that it could reduce the number of migraine days over a 12 -week period compared to placebo.

Ajovy (fremanezumab) is the second CGRP inhibitor to be approved for marketing after Novartis and Amgen’s Aimovig (erenumab), which got the green light in May and is dosed monthly, and ahead of late-stage rivals from Eli Lilly (galcanezumab) and Alder Biopharma (eptinezumab).

Teva would have been earlier to market but the FDA review for its products was delayed by three months while it sorted out some manufacturing issues. With Lilly due to hear from the FDA any day now, potentially setting up a three-way marketing battle, the Israeli drugmaker will be hoping the three-monthly dosing option will be popular with doctors and patients – particularly as there seems to be little to separate the antibodies when it comes to efficacy.

In a statement, Teva said that it had set a list price of $575 for the monthly dose and $1,725 for the quarterly dose, giving an annual cost of $6,900 before rebates and discounts – exactly the same level as Novartis and Amgen positioned Aimovig, and in line with stablished therapies like Allergan’s Botox.

It is estimated that with discounts the annual cost of the drugs could be around the $5,000 mark. However, the US-based Institute for Clinical and Economic Review (ICER) said recently that – even at that lower price – the new drugs should only be used with prior authorisation and after other preventive options such as Botox and anti-epilepsy drugs like topiramate because their long-tern safety is still unclear.

It is estimated that more than 36 million people in the US suffer from migraines, with around 40% of these would be suitable for preventive treatment, and that has led some analysts to predict buoyant sales of the CGRP inhibitors.

GlobalData said recently that it expects the market for migraine drugs to grow at more than 10% a year to reach almost $9bn by 2026, with the prevention category driven by the injectable CGRP inhibitors.

”Market share is going to come down to…variables such as frequency of administration, position to market, and market access strategy,” according to GlobalData analyst Rahael Maladwala.

“Each drug has its own set of advantages; Aimovig will be the first to market, Eli Lilly’s has significant experience in marketing drugs, and an extensive sales force, while both of the other drugs have a quarterly dosing regimen compared to monthly.”

On balance, GlobalData is putting Aimovig out in front in 2026 given its first-mover advantage generating nearly $1.4bn in sales in the seven major pharma markets (US, France, Germany, Italy, Spain, UK, and Japan).  Teva filed Ajovy in Europe earlier this year, but here it will also lag behind Aimovig as Novartis and Amgen picked up EMA approval for their drug in July.

Analysts at Jefferies have suggested Ajovy could become a $500m product in 2022, which will go some way towards counteracting the decline in sales of Teva’s blockbuster multiple sclerosis therapy Copaxone (glatiramer acetate), its rapidly ageing cash-cow product.

Since Schultz took the helm last year, Teva has been shedding staff and restructuring the business to cut costs, selling off its women’s health business for almost $2.5bn in order to pay down a very high level of debt stemming from its $39bn acquisition of Allergan’s generics business Actavis in 2015.

Ajovy is one of 23 New Drug Application (NDA) approvals Teva is targeting between fiscal 2019 and fiscal 2023 to help replace Copaxone and drive top-line growth, along with other new products such as movement disorder therapy Austedo (deutetrabenazine).
