Innovation in small markets

The introduction of new treatment technologies typically occurs where there is a large market.  A lot of innovations are developed to treat disease that affect a large number of people in the developed world because the financial returns are large.  It is less likely to observe innovation in the treatment of rare diseases or diseases…

Prior authorization and opioid abuse

An interesting article by Cochran et al. (2017) examines whether health plan prior authorization rules can help prevent opioid abuse.  The authors use Pennsylvania Medicaid data from 2010 to 2012.  The data included both fee-for-service and managed care enrollees. The authors measured opioid abuse based on diagnosis codes for opioid use disorder (304.0, 304.00, 304.01,…

Predicting Real-World Effectiveness of Cancer Therapies Using OS and PFS Clinical Trials Endpoints

Clinical trials for cancer treatments aim to demonstrate whether one treatment is better than another. What is of most interest to patients, providers and payers, however, is which treatment works best in the real-world, not in a randomized controlled trial. Further, clinical trials often use progression free survival to measure treatment outcomes rather than overall…

Highlights from the 2017 ISPOR Conference

Over the past few days, I have been attending the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) 2017 Annual Conference in Boston. The session had a number of interesting presentations. While I was not able to catch them all, below are links to a few highlights. Darius Lakdawalla, Defining and Measuring Value in Healthcare…

FDA Hedges

Pharmaceutical companies face major risk.  There is risk that the drugs they are researching don’t work (e.g., lack of efficacy) or are not safe.  There is risk that health insurers or government payers will not cover their treatment.  And there is risk that the FDA will not approve a drug after a Phase III clinical trial.…

Does drug detailing affect prescribing patterns?

The obvious answer seems to be ‘yes’.  Why would pharmaceutical companies spend billions of dollars on drug detailing (i.e., visits by pharmaceutical representatives to physicians to explain drug benefits) and drug samples if they don’t work?   When I say billions, I mean billions: A new study by Datta and Dave (2017), however, finds that drug…

Drug approval and reimbursement when clinical trials use surrogate endpoints

An interesting paper from some of my colleagues at Precision Health Economics: Approval of new drugs is increasingly reliant on “surrogate endpoints,” which correlate with but imperfectly predict clinical benefits. Proponents argue surrogate endpoints allow for faster approval, but critics charge they provide inadequate evidence. We develop an economic framework that addresses the value of…
