SUPPLEMENTARY INFORMATION:
I. Background
In 1962, Congress amended the FD&C Act to require that new drugs be
proven effective for their labeled indications, as well as safe, in
order to obtain FDA approval (Drug Amendments of 1962 (Pub. L. 87-
781)). These amendments also required FDA to conduct a retrospective
evaluation of the effectiveness of the drug products that FDA had
approved as safe between 1938 and 1962. FDA contracted with the
National Academy of Sciences/National Research Council (NAS/NRC) to
make an initial evaluation of the effectiveness of over 3,400 products
that had been approved only for safety between 1938 and 1962. The NAS/
NRC reports for these drug products were submitted to FDA in the late
1960s and early 1970s. The Agency reviewed and reevaluated the reports
and published its findings in Federal Register notices. FDA's
administrative implementation of the NAS/NRC reports was called the
DESI. DESI covered the approximately 3,400 products specifically
reviewed by the NAS/NRC, as well as the even larger number of IRS
products that entered the market without FDA approval. If FDA's final
DESI determination classifies a drug product as lacking substantial
evidence of effectiveness for one or more indications, that drug
product and those IRS to it may no longer be marketed for such
indications and are subject to enforcement action as unapproved new
drugs.
II. Final Resolution of Hearing Request Regarding Potassium
Aminobenzoate Oral Preparations Under Docket No. FDA-1977-N-0015
(Formerly 77N-0187); DESI 7663
In a Federal Register notice published on August 28, 1970 (35 FR
13755), FDA announced its evaluation of a report received from the NAS/
NRC under DESI 7663 regarding POTABA (potassium aminobenzoate) Tablets,
Capsules, Powder, and Envules, New Drug Application (NDA) 007663, held
by Glenwood LLC (formerly known as Glenwood Laboratories, Inc.), 83
Summit St., Tenafly, NJ 07670 (herein after ``Glenwood''). The notice
stated that the drug products were possibly effective in the treatment
of scleroderma, dermatomyositis, morphea, linear scleroderma,
pemphigus, and Peyronie's Disease and lacked substantial evidence of
effectiveness for the treatment of rheumatoid arthritis, sarcoidosis,
and pulmonary fibrosis. Glenwood, and any other person marketing such
drug products without approval, was given 60 days to revise its
labeling to delete those indications for which substantial evidence of
effectiveness was lacking and 6 months to submit data to provide
substantial evidence of effectiveness for the indications for which the
drug was regarded as possibly effective. The notice stated that, at the
end of the 6-month period, FDA would evaluate the data to determine
whether substantial evidence of effectiveness had been provided, and,
if it had not, FDA would initiate the withdrawal of approval of NDA
007663 under section 505(e) of the FD&C Act (21 U.S.C. 355(e)).
Glenwood did not submit data to provide substantial evidence of
effectiveness for the indications for which the drug was regarded as
possibly effective within the period provided by the 1970 Federal
Register notice, and the Agency issued a NOOH on the proposed
withdrawal of approval of NDA 007663 in the Federal Register of
February 4, 1972 (37 FR 2688).
In response to a court order, FDA published a notice in the Federal
Register on December 14, 1972 (37 FR 26623), which stated that POTABA,
among other drugs, could remain on the market pending completion of
further scientific studies.
In a Federal Register notice published on August 19, 1977 (42 FR
41922), the Agency revoked the exemption granted in the December 14,
1972, notice pursuant to which POTABA had remained on the market
pending its continued study. In a separate NOOH for DESI 7663, also
published in the Federal Register of August 19, 1977 (42 FR 41921), FDA
noted that Glenwood did not submit data providing substantial evidence
of effectiveness and that no other person had submitted data or
protocols or expressed an intention to perform clinical studies on
potassium aminobenzoate. This notice reclassified the possibly
effective indications to lacking substantial evidence of effectiveness
and proposed to issue an order under section 505(e) of the FD&C Act
withdrawing approval of Glenwood's NDA and all amendments
[[Page 13295]]
and supplements thereto on the grounds that new information, evaluated
together with the evidence available when the application was approved,
showed there is a lack of substantial evidence that the drug is
effective under the conditions of use prescribed, recommended, or
suggested in the labeling. The Agency again invited Glenwood, and any
other interested person(s) who would be adversely affected by the
withdrawal of approval of NDA 007663, to submit: (1) On or before
September 19, 1977, a written notice of appearance and request for
hearing and (2) on or before October 17, 1977, the data, information,
and analyses relied upon to justify a hearing.
On September 12, 1977, Glenwood filed a written notice of
appearance and requested a hearing, and on October 17, 1977, Glenwood
submitted data in support of its hearing request. Along with these
submissions, Glenwood requested that the Agency delay action on the
hearing request until the firm had conducted another placebo-controlled
study. Subsequently, Glenwood initiated a clinical trial at the
Downstate Medical Center of the State University of New York and
supplemented its hearing request with additional data, including a
progress report on the clinical trial of POTABA conducted at the
Downstate Medical Center.
Following a meeting between Glenwood and FDA on November 18, 1985,
Glenwood sponsored another controlled clinical trial, and the final
study report was submitted on February 4, 1993.
By letter dated October 21, 2010, FDA asked Glenwood whether it
wanted to pursue its pending hearing request regarding POTABA. By
letter dated November 11, 2010, Glenwood affirmed its hearing request.
By letter dated June 8, 2020, FDA again asked Glenwood whether it
wanted to pursue its pending hearing request regarding POTABA. By
letter dated July 2, 2020, Cheplapharm Arzneimittel GmbH, successor-in-
interest to Glenwood LLC, stated that it did not wish to pursue the
hearing request for POTABA.
III. Conclusions and Order
There are no outstanding hearing requests regarding potassium
aminobenzoate oral preparations under Docket No. FDA-1977-N-0015, DESI
7663. Therefore, as proposed in the NOOH, FDA withdraws approval of NDA
007663 under section 505(e) of the FD&C Act.
Shipment in interstate commerce of any drug product identified in
this docket under DESI 7663, or any IRS product, that is not the
subject of an approved NDA or abbreviated new drug application is
unlawful as of the effective date of this notice (see DATES). Any
person who wishes to determine whether this notice covers a specific
product should write to Astrid Lopez-Goldberg at the Center for Drug
Evaluation and Research (see FOR FURTHER INFORMATION CONTACT). Firms
should be aware that, after the applicable date of this notice (see
DATES), FDA intends to take enforcement action without further notice
against any firm that manufactures or ships in interstate commerce any
unapproved product covered by this notice.
IV. Discontinued Products
Firms must notify the Agency of certain product discontinuations in
writing under section 506C(a) of the FD&C Act (21 U.S.C. 356c). See
<a href="http://www.fda.gov/Drugs/DrugSafety/DrugShortages/ucm142398.htm">http://www.fda.gov/Drugs/DrugSafety/DrugShortages/ucm142398.htm</a>. Some
firms may have previously discontinued manufacturing or distributing
products covered by this notice without discontinuing the listing as
required under section 510(j) of the FD&C Act (21 U.S.C. 360(j)). Other
firms may discontinue manufacturing or distributing listed products in
response to this notice. All firms are required to electronically
update the listing of their products under 510(j) of the FD&C Act to
reflect discontinuation of unapproved products covered by this notice
(21 CFR 207.57(b)). Questions on electronic drug listing updates should
be sent to <a href="/cdn-cgi/l/email-protection#355071677966755351541b5d5d461b525a43"><span class="__cf_email__" data-cfemail="670223352b3427010306490f0f1449000811">[email protected]</span></a>. In addition to the required update, firms
can also notify the Agency of product discontinuation by sending a
letter, signed by the firm's chief executive officer and fully
identifying the discontinued product(s), including the product National
Drug Code number(s), and stating that the manufacturing and/or
distribution of the product(s) have been discontinued. The letter
should be sent electronically to Astrid Lopez-Goldberg (see FOR FURTHER
INFORMATION CONTACT). FDA plans to rely on its existing records,
including its drug listing records, the results of any future
inspections, or other available information, when it identifies
violative products for enforcement action.
