Botox Maker Allergan Tests Eyelash Lengthener for Baldness
September 2011
Allergan Inc. has moved its eyelash treatment into the second
clinical stage of testing as a therapy for baldness and expects to
see data by the middle of next year, Chief Executive Officer David
Pyott said.
The product, Latisse, was approved in 2008 to aid in eyelash growth,
and generated $82 million last year for the Irvine, California-based
company. Allergan is currently testing Latisse for men and women
against placebo. U.S. regulators generally require three stages of
trials before approval.

The tests follow a business model Allergan successfully implemented
with Botox, its top-selling product with $1.42 billion in revenue
last year. Initially approved for therapeutic uses in 1989, Botox’s
wrinkle-smoothing properties were identified as a side effect. The
product was then cleared in 2002 as an injection to smooth frown
lines between the brows. Latisse is a version of Allergan’s glaucoma
drug Lumigan, which was found to stimulate lash growth as a side
effect of therapeutic treatment.
“The docs used to start laughing, because there are patients luckily
that only have glaucoma in one eye and so they’d come in and say,
‘Doc I’ve got these beautiful eyelashes over here, what should I
do?’” Pyott said today during an interview in New York. Now, for
baldness, “We know anecdotally it works. The question is, how well
does it work?”
Allergan declined 39 cents, or less than 1 percent, to $78.18 at 4
p.m. in New York Stock Exchange composite trading. The shares have
gained 14 percent this year.
Added Sales
Latisse may gain up to an additional $200 million to $500 million in
annual sales by 2020 if it’s proven to spur hair growth, estimated
Ronny Gal, an analyst with Sanford C. Bernstein & Co. in New York.
The product is designed to work similarly to other hair-loss
therapies such as Johnson & Johnson’s Rogaine, said Gal, who
recommends buying Allergan shares.
“It will grow hair from the existing follicle, and help you maintain
the hair you’ve got,” Gal said in a telephone interview today. “It’s
clear it works in principle, because we know it grows eyebrows and
we know it grows lashes.”
Allergan won approval last month for the use of Botox as a therapy
for urinary incontinence, and in October as a treatment for chronic
migraine headaches. The company estimates the product will produce
$1.55 billion to $1.59 billion in revenue this year, and foresees
about $100 million in sales from Latisse.
