Characteristics of Clinical Trials to Support Approval of Orphan vs Nonorphan Drugs for Cancer

Kesselheim AS - JAMA

  • Innovation Incentives and Competition
  • Regulation and Clinical Evidence
Simple graphic of magnifying glass examining papers to signify reviewing research publications.
Orphan cancer drugs approved between 2004 and 2010 had pivotal trials with significantly smaller sample sizes compared to trials for non-orphan drugs, were less likely to be randomized or double-blinded, and more frequently reported serious adverse events. These findings suggest that the regulatory pathway for orphan drugs relies on less rigorous trial designs and surrogate endpoints, raising questions about the adequacy of evidence supporting their approval relative to nonorphan cancer drugs.

Off-Label Drug Use and Promotion: Balancing Public Health Goals and Commercial Speech

Kesselheim AS - American Journal of Law & Medicine

  • Price, Value, and Access
  • Regulation and Clinical Evidence
Simple graphic of magnifying glass examining papers to signify reviewing research publications.
Off-label drug use accounts for approximately 21% of prescriptions overall, yet 73% of off-label uses lack evidence of clinical efficacy. The FDA’s blanket prohibition on manufacturer promotion of these unapproved uses faces growing legal challenge under the commercial speech doctrine, as courts have increasingly applied the Central Hudson test to side with manufacturers’ First Amendment claims. The author proposes a “scaled oversight” framework that would replace the current all-or-nothing approach by categorizing off-label uses into subtypes (genotypic, phenotypic, and dosing variants) and providing expedited FDA review for biologically plausible extensions while maintaining stricter requirements for more substantial departures from approved uses.

University-based biomedical innovation relies on patents to allocate ownership and control, but excessive upstream patenting of genes and molecular targets can hinder follow-on research through costly cross-licensing, while limiting such patents risks allowing private firms to commercialize publicly funded discoveries without compensating academic innovators. Drawing on recent court cases, the article examines this tension and proposes mechanisms such as basic science patent pools and mandatory arbitration to balance rewards for foundational discoveries in the public sector with incentives for continued biomedical innovation.

The authors analyze how the Supreme Court reversed its prior expansive interpretation of ERISA preemption of state-law claims against managed care organizations, marking a significant shift in the legal landscape governing patients’ ability to sue health plans for denials of care. This jurisprudential reversal has important implications for the balance between federal uniformity in employee benefit plan regulation and state-level protections for patients in managed care settings.
