On Thursday, May 19, 2015, the Energy and Commerce Committee
of the House of Representatives voted 51 to 0 to approve the 21st
Century Cures Act (“the Cures Act”) which would, if passed by the full
House and Senate and signed by the President bring about a number of significant
changes in NIH research funding, the process of drug development, and the FDA review
of New Drug Applications (“NDAs”). Because the current draft is 300
double-spaced pages in length the focus in this post will be on just six of
those pages--“Sec. 2001. Development
And Use Of Patient Experience Data To Enhance Structured Risk-Benefit
Assessment Framework.” While there are likely to be some changes to the current
draft, given the overwhelming bipartisan support in the House, it seems that
much, if not all, of the current draft will become law.
Section 2001 of the Curs
Act consists of two subsections, currently denominated (x) and (y). Section 2001 would appear to require very
little change to the current approach of the FDA to drug approval. Section 2001 Subsection x (1) states that
“The Secretary shall implement a structured risk-benefit assessment framework
in the new drug approval process [A] to facilitate the balanced consideration
of benefits and risks; and [B] to develop a consistent and systematic approach
to the discussion of…the benefits and risks of new drugs.” The current draft of
Sec. 2001 Subsection (x) 2 contains the proviso that “Nothing in Paragraph (1)
“shall alter the criteria for evaluating an application for premarket approval
of a drug.” The apparent focus of this subsection (x) is to bring greater
clarity and consistency to the FDA’s weighing of risks versus benefits. This is
an unobjectionable goal, if somewhat difficult to implement. For example, one
cancer drug may cause severe skin reactions while increasing overall survival
by one month, while another drug for the same form of cancer may cause severe
gastric effects while increasing overall survival by 1.2 months. Comparing the
risks and benefits of those two drugs is obviously difficult to do. It is that difficulty that may be the
objective of the much more interesting Subsection (y).
Subsection (y) is
entitled “Development And Use Of Patient Experience Data To Enhance Structured
Risk-Benefit Assessment Framework.” Subsection
(y) 1 requires the Secretary of HHS, over a period of 2 to 3 years, to a
promulgate a number of guidances and establish procedures by which non-NDA
sponsor entities may submit patient experience research proposals for feedback
from the Secretary as well as patient experience data and data analyses. Patient experience data, or, as it is also
known, patient-reported outcomes data has been a field of interest in clinical
research for a number of years. Patient-reported outcomes was the subject of an
FDA Guidance issued in 2009 (“2009 Guidance”). The 2009 Guidance recognized the value of
assessing patient experience endpoints in clinical trials and encouraged
patient input in developing the instruments to be used in assessing patient
reported outcomes or experience:
Item
generation should include input from the target patient population to establish
the items that reflect the concept of interest and contribute to its
evaluation. The population will help generate item wording, evaluate the
completeness of item coverage, and perform initial assessment of clarity and
readability.
However, the
approach to patient experience data in the Cures Act goes well beyond the 2009 Guidance. Subsection (y) provides the
Cures Act definition of patient experience data:
In
this subsection, the term ‘patient experience data’ means
data collected by patients, parents, caregivers, patient
advocacy organizations, disease research foundations, medical researchers,
research sponsors or
other parties determined appropriate by the Secretary
that is intended to facilitate or enhance the
Secretary’s risk-benefit
assessments, including information about the impact of a disease or a therapy on
patients’ lives.
The statutory
inclusion of data collected by
“patients, parents, caregivers, patient advocacy organizations, [and] disease
research foundations” is radically different from the drug-sponsor driven
approach that was addressed in the 2009 Guidance. Bringing data collected by
persons or entities other than the drug sponsor into the New Drug Approval process (or the sNDA process of approving additional indications or major label changes) would be a fundamental change in the concept of data to be used by the FDA in new drug review and would significantly increase the role of patients and
patient organizations in the drug approval process itself. If so, the 21st Century Cures Act’s
effect on drug development might be as dramatic as the title of the Cures Act
suggests.
