Improving Drug Approval Pathways
for Ultra-Rare Diseases WITHOUT Surrogate Endpoints for
Clinical Trials
An important legislative initiative for The National Organization Against
Rare Cancers is to address the lack of clear
FDA approval pathways if an ultra-rare disease has no
established (validated) surrogate endpoints upon which to base
the "accelerated approval" of a new drug.
Legislation addressing this would result in modest reform of the Food,
Drug and Cosmetic Act to result in a unique pathway for drug
development for patients with extraordinarily rare
diseases. This pathway could be utilized by a
pharmaceutical company in situations where clinical trials are
impossible to perform, yet clinical data and other supportive
data present a compelling picture that the new agent would
provide some benefit to the patient. A proposed
regulatory paradigm would be to require
demonstration by the drug sponsor to the FDA that indeed
clinical trials cannot be done, and are even incapable of utilizing the
accelerated approval mechanisms that exist to help
foster some types of drugs approvals. The language in
this legislative initiative, now being drafted, sets very strict criteria that the drug company and
FDA must follow, and has safeguards preventing abuse of
approval based on more "relaxed" standards than
normally seen. NOARC appreciates how sensitive some
advocacy groups and other bodies are to the perception of
"lower" standards for efficacy approval for new
agents for life-threatening diseases. This unique
pathway is envisioned for only extraordinary circumstances,
but NOARC feels that the pathway might occasionally provide
some hope to some patients who otherwise would die of their
ailment without this pathway.
Improving Drug Approval Pathways
for Ultra-Rare Diseases WITH Surrogate Endpoints for Clinical
Trials
Another important legislative initiative of NOARC is passage
of legislation that will help foster drug development for
diseases that have established surrogate endpoints for
clinical trials, but have patient populations too rare to
receive full, final FDA approval. As with the related
legislative issues above, this legislation would also result
in modest reform of the Food, Drug and Cosmetic Act to
result in a much faster, common sense pathway for drugs
approved for patients with Rare Cancers by the accelerated
approval mechanisms currently in place at the FDA. This
piece of legislation focuses on the esoteric, yet important
phase of drug development that occurs AFTER accelerated
approval, but BEFORE full, final approval of a drug for a
life-threatening illness. The legislation addresses the
so-called "fugue state," or "quagmire state" of
post-marketing confirmatory trials in ultra-rare disease
settings. The legislative relief under development
would allow a quality "body of data" to take the place of
"adequate, well-controlled clinical trials" in exceptional
circumstances where it is demonstrated to FDA that the usual
pathway is not feasible due to rarity. NOARC considers
these reform efforts to be very mainstream since current
standards for accelerated approval of new agents are not
affected. Without reform like this, predictable access to
helpful drugs approved conditionally by the accelerated
approval mechanism, will never be assured for patients in
continual need. One of the Advisory Committees to the FDA,
the Oncology Drugs Advisory Committee, proposed this very
reform at its November, 2005 meeting with FDA. So in
this case, NOARC is serving as the messenger to have FDA be
allowed to carry-through on what its own advisory committee
recommended. A Citizen's Petition
