Medical Product Innovation and Regulation: Benefits and Risks


Prior to being marketed in the United States, medical
products are reviewed for safety and effectiveness, among
other things, by the Food and Drug Administration (FDA).
Medical products regulated by FDA include prescription
drugs, medical devices, and biologics. When evaluating a
product, FDA weighs the potential benefits of a medical
product against the potential for certain harms associated
with the use of that same product. It is in this context that
Congress and FDA  have established both premarket and
postmarket requirements for medical products, as well as
expedited development and review pathways for certain
medical products for serious diseases with few available
treatment options. In establishing these expedited pathways,
Congress and FDA  have acknowledged  an implicit trade-
off between reducing time to marketing and a potentially
less complete safety profile upon approval.

History \of   Medical Product Reguflation,
The Biologics Control Act of 1902 (P.L. 57-244) was the
first attempt to regulate a pharmaceutical product at the
national level. It was also the first premarket approval
statute, in contrast to a retrospective postmarket product
evaluation. The act focused on the manufacturing process
and required that manufacturing facilities be inspected
before a federal license was issued to market the biologic.

The regulation of drugs began with the Pure Food and
Drugs Act of 1906 (P.L. 59-384). The 1906 law did not
involve premarket control over new drugs to ensure safety
and did not include inspections or any other regulation of
manufacturing facilities. Rather, the law focused on the
drug label, which could not be false or misleading, and
required that the presence and amount of certain dangerous
ingredients (e.g., alcohol, cocaine) be listed. In addition, it
defined adulterated with reference to the U.S.
Pharmacopoeia  and National Formulary standards for
purity, quality, and strength. It prohibited the introduction
into interstate commerce of misbranded or adulterated
drugs and food.

In 1938, Congress replaced the Pure Food and Drugs Act
with the Federal Food, Drug, and Cosmetic Act (FFDCA).
The FFDCA   required that drug manufacturers submit, prior
to marketing, a new drug application (NDA) demonstrating,
among  other things, that the product was safe. In addition,
the FFDCA  expanded  the prohibition of the introduction
into interstate commerce of misbranded or adulterated
products to include therapeutic devices and cosmetics. The
FFDCA   also included some controls over manufacturing
establishments, including an authority to inspect such
facilities. In 1962, Congress passed the Kefauver-Harris
Drug Amendments   to the FFDCA  (P.L. 87-781), which
required that manufacturers provide substantial evidence
of drug effectiveness, in addition to safety.


The Medical Device Amendments   of 1976 (MDA,  P.L. 94-
295) was the first major legislation enacted to address the
premarket review of medical devices, and it included a
number  of postmarket requirements as well (e.g., current
good manufacturing practices, or CGMPs). The MDA
established a risk-based method for classifying and
regulating medical devices, and established two premarket
regulatory pathways: premarket approval (PMA) and
premarket notification (5 10(k)).

Speeding Access to Medica Products
Over the years, Congress and FDA have made
modifications to the established standard premarket review
pathways in an attempt to improve access to medical
products that would meet a compelling unmet need. The
aim of congressional reforms to FDA's review process has
primarily been to speed medical product entry to market.
These changes are often described as benefiting patients by
allowing an innovative drug or device to be more rapidly
available in a potentially dire situation for the patient. On
the other hand, the less fully regulators explore the safety
and effectiveness of medical products before marketing
relative to standard review, the higher the odds of
unidentified adverse events. The appropriate balance
between this risk of unidentified adverse effects and having
faster access to beneficial new drugs and devices-and
therefore the ideal degree of scrutiny of their safety and
effectiveness prior to their marketing-is and will continue
to be a matter of debate.

Broadly, in an effort to improve access to medical products
for serious or life-threatening diseases with limited
treatment options, FDA and Congress have established
mechanisms  to (1) expand access to drugs and devices that
are still under investigation, and (2) expedite the actual
premarket development and review processes for new
products coming onto the market. As used in the following
sections, the term drugs generally includes biologics.

In general, a drug or device may be provided to patients
only if FDA has cleared or approved its marketing
application or authorized its use in a clinical trial under an
investigational new drug (IND) or investigational device
exemption (IDE) application. In certain circumstances,
patients may be able to obtain access to investigational
drugs and devices outside this framework through expanded
access (compassionate use) programs. In 1987, FDA issued
a rule creating procedures through which patients could
request permission from FDA to obtain an investigational
drug outside a clinical trial (treatment IND program; 52
Federal Register 19466). This pathway was codified in the
FDA  Modernization Act of 1997 (FDAMA,   P.L. 105-115)
and expanded to include investigational devices. In the
