“K-RAS testing should be routinely conducted in
all colorectal cancer patients immediately after
diagnosis to ensure the best treatment strategies
for the individual Patient”

- Dr. Eric Van Cutsem, presenter at the June 2008 American

Society of Clinical Oncology meeting

FDA recommends genetic screening prior to
treatment with Abacavir

ROCKVILLE, Md -- July 24, 2008 -- The US Food and Drug Administration (FDA) has
issued an alert regarding serious, and sometimes fatal, hypersensitivity reactions (HSRs)
caused by abacavir (Ziagen) therapy in patients with a particular human leukocyte antigen
(HLA) allele, HLA-B* 5701.

Genetic tests for HLA-B*5701 are already available, and all patients should be screened for
the HLA-B*5701 allele before starting or restarting treatment with abacavir or abacavir-
containing medications.

“FDA has approved the expanded use of
Selzentry… to include adult patients with CCR5-
tropic HIV-1 virus who are starting treatment for
the first time.”
