Hydrochloride; Final Decision on Proposal To Withdraw Approval of New
Drug Application; Availability of Final Decision
AGENCY: Food and Drug Administration; Health and Human Services (HHS).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA or the Agency) is
announcing that the Initial Decision of the Administrative Law Judge
(ALJ), that Vasodilan containing Isoxsuprine Hydrochloride had not been
shown to be supported by substantial evidence consisting of adequate
and well-controlled studies to be effective for treating symptoms
relating to senile dementia of the Alzheimer type (SDAT) and multiple
infarct dementia and peripheral vascular disease, is the final decision
of the Commissioner of Food and Drugs (the Commissioner).
DATES: This notice is applicable July 15, 2020.

Scientific Integrity, Food and Drug Administration, 10903 New Hampshire
Ave., Bldg. 1, Rm. 4206, Silver Spring, MD 20993, 240-402-5931.
SUPPLEMENTARY INFORMATION: Several parties to the hearing, including
the new drug application (NDA) holder and identical, related, or
similar (IRS) product manufacturers, filed exceptions to the ALJ's
Initial Decision. FDA recently requested that the current owner of the
NDA and successors-in-interest to IRS product manufacturers who
submitted timely exceptions to the ALJ's Initial Decision affirm,
within a specific timeframe, their interest in pursuing their appeals
of the ALJ's Initial Decision. FDA did not receive any responses within
the specified timeframe. Accordingly, FDA now deems those exceptions as
withdrawn. Consequently, the proceeding is in the same procedural
position as if no exceptions to the ALJ's Initial Decision had been
filed. Therefore, the ALJ's Initial Decision has become the final
decision of the Commissioner by operation of law.
I. Background
In 1962, the Federal Food, Drug, and Cosmetic Act (FD&C Act) was
amended by the Drug Amendments Act of 1962, and these amendments
provided that new drugs could no longer be approved unless both safety
and efficacy had been established for them. As amended, the FD&C Act
also required FDA to evaluate drugs approved as safe between 1938 and
1962 to determine whether such drugs were effective and to withdraw
approval for any NDA where there was not substantial evidence of the
drug's effectiveness. The person contesting the withdrawal of the
approval had the burden of coming forward with evidence of
effectiveness for the drug. FDA's review of these pre-1962 drugs is
known as the Drug Efficacy Study Implementation program.
In a notice published in the Federal Register of July 11, 1972 (37
FR 13565, available at https://www.govinfo.gov/content/pkg/FR-1972-07-11/pdf/FR-1972-07-11.pdf), after receiving reports from the National
Academy of Sciences/National Research Council, Drug Efficacy Study
Group, FDA stated that Vasodilan Injection and Tablets containing
Isoxsuprine Hydrochloride lacked substantial evidence of effectiveness
for several indications. In a notice published in the Federal Register
of May 25, 1979 (44 FR 30443, available at https://www.govinfo.gov/content/pkg/FR-1979-05-25/pdf/FR-1979-05-25.pdf), the Director of the
Bureau of Drugs (now the Center for Drug Evaluation and Research),
after reviewing all the data previously submitted, concluded that
Vasodilan lacks substantial evidence of effectiveness for its labeled
indications, and proposed to withdraw approval of the NDA and issued a
notice of opportunity for hearing on a proposal to withdraw approval of
Vasodilan.
Mead Johnson, the NDA holder of Vasodilan (NDA 11-832) submitted
data intended to support the effectiveness of Vasodilan for other
indications, including: (1) Relief of symptoms associated with SDAT
and/or multiple infarct dementia; (2) relief of symptoms associated
with peripheral vascular disease of arteriosclerosis obliterans,
thromboangiitis obliterans, and Raynaund's disease; and (3) relief of
symptoms of uterine motility, including premature labor, dysmenorrhea,
and threatened abortion.
Mead Johnson and multiple IRS product manufacturers responded to
the notice of opportunity for a hearing and submitted requests for a
hearing. By notice published in the Federal Register on September 28,
1984 (49 FR 38363, available at https://www.govinfo.gov/content/pkg/FR-1984-09-28/pdf/FR-1984-09-28.pdf), the Commissioner granted a hearing;
however, the Commissioner only granted a hearing concerning the use of
Vasodilan in treating symptoms related to: (1) SDAT or multiple infarct
dementia and (2) peripheral vascular disease. Although Mead Johnson
requested a hearing on the issue of Vasodilan's effectiveness in
relieving symptoms of uterine motility, including premature labor,
dysmenorrhea, and threatened abortion, Mead Johnson later abandoned
this indication and consented to withdrawal of Vasodilan's approval for
it (see id.). Following the submission of written testimony and
documentary evidence, an ALJ, Daniel J. Davidson, conducted a hearing
and issued his Initial Decision on August 20, 1986. The ALJ found that
the effectiveness of Vasodilan had not been shown to be supported by
substantial evidence and, as a result, ordered that the approval of the
NDA be withdrawn. Mead Johnson and certain IRS product manufacturers
timely appealed the ALJ's Initial Decision by filing exceptions with
the Commissioner under 21 CFR 12.125.
Separately, by notice published in the Federal Register of February
11, 2009 (74 FR 6896), FDA withdrew approval of Vasodilan. The current
NDA holder and successor to Mead Johnson, Apothecon, c/o Bristol-Myers
Squibb Co. (BMS), had requested that FDA withdraw approval of the
application because the drug product was no longer marketed;
additionally, BMS waived its opportunity for a hearing on the
withdrawal.
On November 9, 2017, FDA sent letters to BMS and the successors-in-
[[Page 42883]]
interest to the IRS product manufacturers who submitted timely
exceptions, to determine whether the companies remained interested in
pursuing their appeals of the ALJ's Initial Decision. FDA informed the
companies that, if they did not respond and affirm their desire to
pursue their appeals by January 8, 2018, the Office of the Commissioner
would conclude that the companies no longer wish to pursue the appeal
of the ALJ's Initial Decision and will proceed as if the appeals have
been withdrawn. The Office of the Commissioner did not receive a
response from any of the companies by the given date; therefore, the
Commissioner now deems the exceptions withdrawn.
II. Conclusion and Order
Given that the exceptions have been deemed withdrawn, this
proceeding is now in the same procedural posture as if no exceptions
had ever been filed. When parties do not file exceptions to the ALJ's
Initial Decision, and the Commissioner does not file a notice of
review, the ALJ's Initial Decision becomes the final decision of the
Commissioner (see 21 CFR 12.120(e)). FDA will publish a notice in the
Federal Register when an initial decision becomes the final decision of
the Commissioner without appeal to or review by the Commissioner (see
21 CFR 12.120(f)).
Pursuant to the findings in the ALJ's Initial Decision, under
section 505(e) of the FD&C Act (21 U.S.C. 355(e)), there is a lack of
substantial evidence that Vasodilan will have the effect it purports or
is represented to have under the conditions of use prescribed,
recommended, or suggested in its labeling for: (1) SDAT or multiple
infarct dementia and (2) peripheral vascular disease. Distribution of
products subject to the Initial Decision in interstate commerce without
an approved application is prohibited and subject to regulatory action
(see, e.g., sections 505(a) and 301(d) of the FD&C Act (21 U.S.C.
355(a) and 331(d)).

Management Staff (see ADDRESSES).
