John,

I don't know for nothing!!

But I did learn how to spell Pfizer right.

Good luck to all.

Micrologix Plans to Initiate Clinical Trials for the Treatment of Acne

Micrologix's Bactolysins (cationic antimicrobial peptides) offer
significant potential to treat severe inflammatory acne, as shown by recent
results from the Company's preclinical program. Currently, many strains of
bacteria associated with acne are highly resistant to the traditional
antibiotics used to treat this disease. Micrologix has been developing
Bactolysins that are highly active against these strains and is currently
selecting candidates for further studies. The Company plans to initiate
clinical trials for the treatment of acne in the first quarter of 2000.

Acne is the most common inflammatory skin disease of adolescence and
early adulthood. Nearly 20% of all visits to dermatologists are related to its
evaluation and treatment. While not life-threatening, the characteristic
papules, nodules and pustules occurring on the face, neck and upper body of
acne sufferers can persist for years and have serious adverse psychosocial
effects including depression and withdrawal from society. By conservative
estimates, acne affects 17 million people in the US alone.

The US market for prescription anti-acne medications is approximately
$1.2 billion annually. Current therapy for severe acne includes topical
antibiotics and the use of systemic antibiotics approved for other
indications. Yet increasing resistance to these antibiotics is severely
limiting their use. Topical and systemic retinoids (derivatives of vitamin A)
have recently entered clinical practice as a treatment for moderate to severe
acne. However, these compounds, particularly in systemic form, can have
significant side effects and have been shown to cause birth defects if taken
during pregnancy.

The most important bacterium associated with acne is Propionibacterium
acnes, with secondary infection due to Staphylococcus aureus and
Staphylococcus epidermidis. Antibiotic resistance in P. acnes strains -- and
in the other bacteria associated with acne -- has been reported worldwide. In
fact, the overall incidence of antibiotic resistant P. acnes has dramatically
increased from 20% in 1978 to 62% in 1996. Strains of acne-causing bacteria
now resist both systemic and topical forms of erythromycin, one of the most
widely prescribed antibiotics.

''We're running out of options,'' says Dr. James Leyden, professor of
dermatology at the University of Pennsylvania School of Medicine, a
world-renowned expert in acne therapy and an advisor to Micrologix. ''We
estimate that at least one out of four acne patients is infected with strains
of P. acnes that are resistant to tetracycline, erythromycin and clindamycin.
And these strains also show lower susceptibility to minocycline and
doxycycline than in the past.''

Micrologix's Bactolysins offer significant potential for the effective
treatment of severe acne. Results from our preclinical research program
demonstrate that Bactolysins are non-toxic and non-irritating in animal
models. In addition, the superior activity of Bactolysins against resistant
strains of acne-causing bacteria suggests that these agents may be more
effective than currently available antibiotics. Most importantly, unlike
conventional antibiotics, Bactolysins kill microorganisms such as bacteria by
destroying their cellular membranes, thus preventing bacteria from developing
resistance to Bactolysin compounds. For these reasons, Bactolysins are
considered to be strong drug candidates for the treatment of severe
inflammatory acne. The Company is proceeding with additional preclinical
testing of several of its lead Bactolysins and plans to initiate clinical
trials in the first quarter of 2000.
