James MacKay grew up in Scotland, and was encouraged by his father to pursue a career in business –but not the family business. Instead he earned a PhD in genetics and began a long stint with AstraZeneca, eventually jumping across the pond and all the way to San Diego. He continued with A companies like Ardea an now Arthrosi and Aristea, where he’s even done a deal with Arena.
In this episode of the HealthBiz podcast James talks about how he and his team at Aristea Therapeutics are applying their decades of experience to develop a drug they licensed from AstraZeneca. The first indication is PPP –no not purchasing power parity or the paycheck protection program– but palmoplantar pustulosis, a nasty illness with no good treatments today. We talk about why good drugs get left on the shelf at big pharma, and the future of the biotech industry and San Diego.
Mike Rea is a self-professed bad scientist and bad musician but despite –and perhaps even because– of those limitations, he’s built some pretty good companies.
As CEO of IDEA Pharma and Protodigm, he makes a distinction between the invention of a drug in the lab and the level of innovation in its development. Although he compares the work to that of a CRO, he clarifies that it’s really a bit upstream from there. And in the future, if you hear Protodigm start talking about being a “Pre-RO,” you’ll know that little brainstorm came out of this podcast.
Mike runs a record company, aptly named Medical Records and hosts his own book club slash podcast about innovation in pharma.
Drug developers must demonstrate that new medications are safe and effective in order to win regulatory approval. The gold standard in cardiac safety testing has been the Thorough QT study, a separate, expensive trial that is typically conducted late in the clinical development process.
The international body that informs drug development standards has just revised its stance to support definitive QT testing based on ECGs collected during existing early-stage trials. iCardiac Technologies, where I’m a board member, pioneered this approach in conjunction with the FDA. I asked iCardiac’s CEO Alex Zapesochny to explain what is happening.
What is the ICH and why does it matter for clinical trials?
The International Council for Harmonisation is an international forum for regulators to harmonize drug approval practices. The group includes pharmaceutical industry representatives and regulators from the United States, Canada, the European Union, Japan and Switzerland.
As for the clinical trials process, the ICH aims to make recommendations toward achieving greater harmonization in the interpretation and application of technical guidelines and requirements related to research and development of new drugs. These guidelines can assist with pharmaceutical product registration and help reduce or avoid duplication of testing carried out during R&D.
ICH has issued a regulatory revision for cardiac safety testing. What specifically has it done?
Currently, the FDA and other regulators expect nearly all new drugs to be tested using a costly, stand-alone Thorough QT (TQT) study to assess a drug’s effect on the QT interval before market approval. This is an important step, since a prolonged QT interval is associated with a heightened risk for arrhythmias and possible sudden cardiac death. The latest revision adopted by the ICH states that data from ECGs collected during routine Phase I or other early clinical trials may be used to conclusively demonstrate a drug’s QT effect. This approach relies on intensive, high quality ECG analysis and the use of exposure response modeling.
What led to the change?
Regulators around the world want to make the drug development process as safe, precise and efficient as possible. The ICH revision emerged a year after the U.S. Food and Drug Administration helped to organize a meeting of thought leaders to discuss the results of a successful prospective validation study demonstrating the ability to determine cardiac safety much earlier in the development process. This revision is likely the most significant regulatory shift in cardiac safety since the original E14 guidance was adopted by the ICH in 2005.
What role did iCardiac play? The FDA?
iCardiac has been championing this alternative approach for several years, including collaborating with thought leaders from the FDA and from industry to help organize a prospective validation study to definitively test this new approach. Ultimately iCardiac sponsored that definitive validation study, and it was overseen by iCardiac personnel and used our proprietary High Precision QT methodology to perform the critical data analysis. Leaders from the FDA have been involved in multiple key ways, including decisions around the validation study design and co-authoring publications about the validation study and its implications. Of course, the FDA is also a participant in the ICH and played a direct role in the new regulatory revision.
What will be the practical implications?
This development provides an alternative path for sponsors with regard to demonstrating the effect of their drug on QT, which is a critical part of gaining market approval for a new drug. By analyzing ECG data from a Phase I or other early clinical study, sponsors can choose to seek a waiver from regulators from having to do a TQT study. The FDA granted the first TQT waiver based on this alternative approach earlier in 2015. So apart from saving time and money, this approach gives drug developers insight into their compound’s QT liability much earlier in the clinical trials process.
What are you doing to let people know more about the implications?
iCardiac will conduct two free public webinars to explain the new ICH guidance and the standards it establishes for receiving a waiver from the Through QT study. Dr. Borje Darpo, a cardiologist and chief scientific officer at iCardiac, will discuss the impact of this regulatory revision on the clinical development process. The webinars will be held on January 12th and January 20th, 2016. You can follow the links below to register for one of iCardiac’s webinars:
