FDA Rejects Over-the-Counter Emergency Contraceptive

Barr receives ‘not approvable’
letter for emergency contraceptive Plan B

FDA recognizes public health importance of ‘wide availability’
and invites additional

submissions by Barr

WOODCLIFF LAKE, N.J., May 6, 2022 /PRNewswire-FirstCall via
COMTEX/ — Barr

Pharmaceuticals, Inc. (NYSE: BRL) today announced that it has received
a Not Approvable Letter

from the U.S. Food and Drug Administration (FDA) for the Company’s
Supplemental New Drug

Application (sNDA) for an Over-the-Counter (OTC) Plan B® emergency
contraceptive product.

Although concluding that Barr’s current application did "not
provide adequate data to support a

conclusion that Plan B can be used safely by young adolescent women
for emergency contraception

without the professional supervision of a [licensed] practitioner,"
the FDA offered Barr two alternative

approaches for seeking approval. First, Barr could "provide additional
data demonstrating that Plan B

can be used safely by women under 16 years of age without professional
supervision." Alternatively,

Barr could "supply additional information in support of a submission
to allow for the marketing of Plan

B as a prescription only product for women under the age of 16 years
and a nonprescription product

for women 16 years and older."

"While we are disappointed that FDA did not approve our application
at this time, we are encouraged

by FDA’s suggestions, and look forward to working with the agency
toward approval of Plan B for over the counter use," said Bruce
L. Downey, Barr’s Chairman and CEO. "In the meantime, we remain

committed to providing Plan B as a prescription only product and to
increasing awareness among the

healthcare provider community and women of this safe and effective
option," Downey added.

Taken within 72 hours of unprotected intercourse, Plan B® has
been shown to reduce the risk of

pregnancy by 89 percent after a single act of unprotected sex. Plan
B is most effective when taken in

the first 24 hours after intercourse. Effectiveness declines as the
interval between intercourse and the start of treatment increases.
The major side effect associated with Plan B is nausea.

Emergency contraception is currently available in 101 countries, 33
of which do not require a

prescription. Emergency contraception is currently available in a
limited number of pharmacies

without an advance prescription from a physician or healthcare provider
in six U.S. states (Alaska,

California, Hawaii, Maine, New Mexico and Washington).

Contraindications for Plan B

Progestin-only contraceptive pills (POPs) are used as a routine method
of birth control over longer

periods of time, and are contraindicated in some conditions. It is
not known whether these same

conditions apply to the Plan B regimen consisting of the emergency
use of two progestin pills. POPs

are not recommended for use in the following conditions: known or
suspected pregnancy;

hypersensitivity to any component of the product; and, undiagnosed
abnormal genital bleeding.

Barr Pharmaceuticals, Inc., a holding company that operates through
its principal subsidiaries, Barr

Laboratories, Inc. and Duramed Pharmaceuticals, Inc., is engaged in
the development, manufacture

and marketing of generic and proprietary pharmaceuticals.
