Scramble to market new eye medicines

- John Miller

Swiss companies Roche and Novartis and other pharmaceut­ical firms are touting new treatments for a blindness causing disease that hits millions of older people, as patent expiries are set to open up one of medicine’s most lucrative markets.

Roche’s experiment­al treatment, faricimab, showed long-lasting effectiven­ess against age-related macular degenerati­on (AMD), the Baselbased drugmaker said this week, potentiall­y reducing the frequency of uncomforta­ble, direct-in-the-eye injections.

Molecular Partners, together with partner Allergan, and Novartis, also released data on new AMD medicines at an industry conference in Chicago.

For years, Lucentis, from Roche and Novartis, and Bayer and Regeneron’s Eylea, have dominated AMD treatment, with combined 2017 sales topping $9bn. However, with patent expiries starting in 2020, the scramble is on to preserve

— or capture — a chunk of one of medicine’s hardest-fought areas, analysts say.

The AMD landscape is getting more crowded and less differenti­ated, with new medicines offering only marginal therapeuti­c improvemen­t while remaining costly, says Baader Helvea analyst Bruno Bulic.

The question is, Bulic says, “how long the cash cow can still be milked before the end?”

Potential pricing reforms under US President Donald Trump could also disrupt the market. The state-administer­ed Medicare health plan for seniors spent $3.25bn in 2016 on Eylea and Lucentis alone.

The Trump administra­tion is seeking ways to lower the cost of drugs on Medicare. That could help Samsung Bioepis of South Korea and Mylan, which are developing biosimilar­s of Lucentis and Eylea, which are expected to be cheaper.

The new drugs will still face competitio­n from Roche’s Avastin, a cancer medicine used for years to treat AMD in many markets despite not being officially approved to do so. Avastin costs just a fraction of Lucentis and Eylea. In September, Novartis, Bayer and Roche lost a bid to stop UK doctors from recommendi­ng Avastin, potentiall­y clearing the way for Britain’s National Health Service to begin broader use of the cheaper drug.

Because new AMD drugs in studies have proven to be as effective, but not necessaril­y better, in helping vision as Eylea and Lucentis, their backers are seeking to underscore other benefits, such as the need for less frequent shots.

Compared with monthly Lucentis injections, data show the potential of faricimab to allow fewer injections while achieving and sustaining the same visual gains”, says Sandra Horning, Roche’s chief medical officer.

Novartis plans to submit its new drug, RTH258, to US and EU regulators in December, with approval due in 2019. It is promoting RTH258 data showing it is better than Eylea at controllin­g fluid in the retina, a hallmark of AMD.

THE QUESTION IS HOW LONG THE AGERELATED MACULAR DEGENERATI­ON CASH COW CAN STILL BE MILKED BEFORE THE END?
