Latest & Greatest AMA Seeks to Ban Direct-toConsumer Advertising Concerned that a growing number of prescription drug and medical device ads may be driving demand for expensive treatments despite the ability of as-effective and less-costly alternatives, the American Medical Association (AMA) recently voted in favor of banning direct-to-consumer advertising. Even though the U.S. Food and Drug Administration (FDA) and Congress are the only entities that have the power to enact such a ban, the AMA views this new policy as a step toward making prescription drugs more affordable, arguing that, as more people seek drugs they may not need, drug prices and money spent on selling them are on the rise. Spending on direct-to-consumer advertising has increased 30 percent in the past two years, amounting to $4.5 billion. At the same time, prescription drug prices have increased nearly 5 percent this year, the AMA explained. “[This vote] reflects concerns among physicians about the negative impact of commercially driven promotions, and the role that marketing costs play in fueling escalating drug prices,” said Patrice A. Harris, MD, MA, the board chair-elect at 18 ASH Clinical News the AMA, in a press release from the agency. “Direct-to-consumer advertising also inflates demand for new and more expensive drugs, even when these drugs may not be appropriate.” The AMA’s new policy calls for convening a physician task force and launching an advocacy campaign to promote more affordable prescription drugs, by demanding choice and competition in the pharmaceutical industry and greater transparency in prescription drug prices and costs. The AMA also plans to monitor pharmaceutical company mergers and acquisitions to determine how they will affect drug prices. As part of the new policy, the AMA will encourage actions by federal regulators to limit anticompetitive behavior by pharmaceutical companies against generic manufacturers through manipulation of patent protections and abuse of regulatory exclusivity incentives. The agency argues that a greater understanding of factors that contribute to prescription drug pricing, including research, development, and manufacturing, is necessary for all health-care stakeholders, including physicians, patients, manufacturers, and payers. Members of the pharmaceutical industry, however, took issue with the AMA’s decision. Tina Stow, of the Pharmaceutical Research and Manufacturers of America, argued that direct-to-consumer advertising offers “scientifically accurate information to patients so that they are better informed about their healthcare and treatment options [and it leads to] important doctor−patient conversations about health that might otherwise not take place.” Sources: American Medical Association, “AMA calls for ban on direct to consumer advertising of prescription drugs and medical devices,” November 17, 2015; The Washington Post, “American Medical Association urges ban on TV drug ads,” November 19, 2015. Researchers Develop Novel Assay to Predict Heparin-Induced Thrombocytopenia A novel PF4-dependent p-selectin expression assay (PEA) has proven effective in detecting platelet-activating heparin-induced thrombocytopenia and thrombosis (HIT) antibodies, according to research presented at the 57th ASH Annual Meeting. These antibodies preferentially recognize heparin/platelet factor 4 (H/PF4) bound to platelet glycosaminoglycans in the absence of heparin, the researchers, led by Anand Padmanabhan, MBBS, MA, PhD, of the Medical Sciences Institute at the BloodCenter of Wisconsin, explained. Dr. Padmanabhan and colleagues compared the diagnostic performance of PEA versus the serotonin release assay (SRA), which is considered the gold standard for HIT testing. Ninety-one serum samples from patients referred for HIT testing (with clinical scores ranging from 0 to 8) were tested using both assays. Samples were considered HIT-positive if patients had intermediate or high 4T scores and PF4 ELISA optical density (OD) values >1; samples were considered HIT-negative if patients had intermediate to high 4T score with PF4 ELISA OD <1. Overall, PEA had greater accuracy for identification of samples from HITpositive patients compared with SRA (0.93 vs. 0.82; p=0.01). “PEA has many attractive features, including its technical simplicity and its ability to allow physicians to identify patients suspected of having a high likelihood of HIT, suggesting that its use may facilitate early diagnosis and improve management of this diagnostically challenging disorder,” the authors concluded.

FDA Grants Accelerated Approval to Daratumumab for Multiple Myeloma The U.S. FDA granted accelerated approval to daratumumab injection for patients with multiple myeloma (MM) who have failed at least three prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent. Daratumumab is the first monoclonal antibody approved for the treatment of MM. The recommended dose of daratumumab is 16 mg/kg administered once every week for eight weeks, then once every two weeks for 16 weeks, followed by once every four weeks until disease progression. The approval was based on a multicenter, open-label study evaluating response rates in 106 patients with relapsed or refractory MM treated January 2016
