Drugmakers race for smart devices
Bid to check inhaler use
LONDON, July 20, (RTRS): Makers of inhalers to treat asthma and chronic lung disease are racing to develop a new generation of smart devices with sensors to monitor if patients are using their puffers properly.
Linked wirelessly to the cloud, the gadgets are part of a medical “Internet of Things” that promises improved adherence, or correct use of the medication, and better health outcomes. They may also hold the key to company profits in an era of increasingly tough competition.
Drugmakers believe giving patients and doctors the ability to check inhaler use in this way could be a big help in proving the value of their medicines to governments and insurers, though they need to tread carefully on data privacy.
Glaxo Smith Kline, Astra Zeneca and Novartis are all chasing the opportunity via deals with device firms including US-based Propeller Health and Australian-listed Adherium, as well as technology players like Qualcomm.
Over the past half century, inhalers have revolutionised care by delivering medicines direct into the lungs and avoiding the serious side effects seen with older oral drugs. But getting patients to take their medication correctly remains a challenge.
“Technique is critical. You might have the world’s best blockbuster drug in an inhaler, but if patients don’t use it properly they won’t get the benefits,” said Omar Usmani, a consultant physician at Imperial College London.
Obstructive
With asthma and chronic obstructive pulmonary disease (COPD) affecting about 500 million people worldwide, the opportunity is large, and reducing serious attacks by improving adherence could save $19 billion a year in US healthcare costs alone, Goldman Sachs analysts estimated in a report last year.
Usmani envisages a future of hightech inhalers that not only record doses but also use gyroscopic and acoustic sensors to check medicine flow, while monitoring the environment for allergens such as pollen. All that data can be fed to remote computer servers known as the cloud.
It is an idea big drug companies have embraced enthusiastically, in the knowledge that they need to find new ways to sell their products as cheap generics undercut long-established brands. The first generic copies of GSK’s Advair, the world’s biggest inhaler with worldwide sales of nearly $6 billion in 2015, are expected to reach the US market next year.
“It’s a race to the starting line,” Propeller CEO David Van Sickle told Reuters, describing the current jockeying among leading pharmaceutical firms.
“Today, there is really no major respiratory pharma company that doesn’t have a programme to add connectivity to their inhaled medicines.”
The field is now at an inflection point. Some inhalers with clip-on sensors are already being supplied to patients, but the drug industry is about to take things to the next level. Next month, Astra Zeneca will start a year-long US clinical trial designed to improve adherence to longterm therapy in nearly 400 patients with COPD using Adherium’s smart inhaler.
If it works as hoped, it could have the same impact on improving clinical outcomes as a completely new medicine, according to Martin Olovsson, Astra Zeneca’s head of respiratory inhalation.
“Many asthma and COPD patients are misusing their medicines, for various reasons — they forget to take them or they don’t understand how to take them properly — and the result of that is less than optimal outcomes,” he said. “This offers a chance to change that dramatically.”
Last year, a smaller study reported in the journal Lancet Respiratory Medicine already showed Adherium’s device increased adherence to preventative medication to 84 percent from 30 percent in New Zealand children with asthma.
Now, with bigger studies, drug companies plan to dig deeper.
“There is still quite a lot of work to be done to understand which type of patients will benefit most,” said Raj Sharma, director of respiratory science and delivery systems at GSK, which is also planning clinical trials.
