BLOCKING Act Would Hurt Generic Drug Access: Attorneys
Former FDA attorneys William Schultz and Margaret Dotzel (both Zuckerman Spaeder) say the BLOCKING (Bringing Low-Cost Options and Competition While Keeping Incentives for New Generics) Act, if passed, “will not accelerate generic drug entry. Instead, it will upend the critical 180-day exclusivity incentive by making it far less predictable and therefore far less valuable.”
In “An Evidence-Based Assessment of the Blocking Act,” Schultz and Dotzel say the legislation is intended to accelerate the entry of generic drugs by limiting the availability of the Waxman-Hatch 180-days of exclusivity.
The attorneys say the incentive has worked by making a significant contribution to accelerating patient access to generics for more than 35 years and has helped to increase the generic share of all prescriptions filled in the U.S. to 92% today.
The authors evaluated available data and five real-world examples to assess whether the legislation’s stated goal would be achieved. “This evaluation revealed that, in the vast majority of circumstances, BLOCKING will not accelerate generic entry, frequently because the second generic applicant will not market its drug upon approval due to patent settlements or ongoing patent litigation,” the attorneys say. “These examples also support the conclusion that, in a number of cases, delays in marketing by the first applicant are not caused by significant quality issues, one of the alleged problems that the legislation’s supporters assert are the impetus for the legislation, but rather by FDA’s own regulatory decisions and bottlenecks.”
The paper concludes that if the bill is passed, fewer generic drug manufacturers are likely to make the significant investment needed to challenge patents on expensive brand-name drugs, even when those challenges could have been successful or resulted in favorable settlements. “The net effect will be that brand-name prices will remain higher for longer, and there will be fewer generic drugs available to patients,” the attorneys say.
