* GLPG1790 has high efficacy against triple-negative breast cancer
* Innovative, targeted approach
* Galapagos plans to initiate clinical trials within one year
Mechelen, Belgium; 22 April 2013 - Galapagos NV (Euronext: GLPG) announced today
that it developed GLPG1790, a novel candidate drug to treat breast cancer.
GLPG1790 has shown high activity against breast tumors that are triple-negative,
for which the absence of estrogen (ER), progesterone (PR) or HER2 receptors
affects the prognosis for recovery, and no targeted therapeutic options are
Breast cancer is a disease in which tumor cells form in the breast tissue; it is
one of the most common types of cancer in women. There are
many different types
of breast cancer, and as a result, there are many options for treatment.
Targeted drug treatments such as Herceptin(®) and Avastin(®) attack specific
types of breast cancer cells. Decisions about the best possible treatment with
targeted drugs are based on tests for the presence of ER, PR and HER2.
Triple-negative breast cancer (tumor cells that have no ER, PR and HER2)
accounts for one-fifth of breast cancers, and it usually affects young women.
There are no targeted drugs available for patients with triple-negative breast
Candidate drug GLPG1790 is a selective and potent inhibitor of a novel breast
cancer target; the candidate drug has proven to be highly active against triple-
negative breast cancer in a mouse xenograft model where it completely blocks
tumor growth. GLPG1790 has good drug-like properties, and safety/tolerability
studies with the candidate drug look favorable. Galapagos will initiate
preclinical studies with GLPG1790, and expects to initiate the first clinical
trials in humans within one year. This novel program is fully proprietary to
"GLPG1790 is the result of a multi-year research program on a novel mechanism of
action discovered with our target discovery platform," says Dr Piet Wigerinck,
Galapagos CSO. "We are pleased to have developed a targeted approach towards
triple-negative breast cancer. Targeted approaches in oncology typically show
good efficacy and less toxicity than chemotherapy."
Galapagos (Euronext: GLPG; OTC: GLPYY) is specialized in novel modes-of-action,
with a large pipeline of four clinical, seven pre-clinical, and 30 discovery
small-molecule and antibody programs in cystic fibrosis, inflammation,
antibiotics, metabolic disease, and other indications.
GLPG0634 is an orally-available, selective inhibitor of JAK1 for the treatment
of rheumatoid arthritis and potentially other inflammatory diseases, about to
enter Phase 2b studies. AbbVie and Galapagos signed a worldwide license
agreement whereby AbbVie will be responsible for further development and
commercialization after Phase 2b. Galapagos has another selective JAK1
inhibitor in Phase 2 in lupus and psoriasis, GSK2586184 (formerly GLPG0778, in-
licensed by GlaxoSmithKline in 2012). GLPG0187 is a novel integrin receptor
antagonist currently in a Phase 1b patient study in metastasis. GLPG0974 is the
first inhibitor of FFA2 to be evaluated clinically for the treatment of IBD;
this program will start a Proof of Concept Phase 2 study this quarter.
The Galapagos Group, including fee-for-service companies BioFocus, Argenta and
Fidelta, has over 800 employees and operates facilities in five countries, with
global headquarters in Mechelen, Belgium. Further information at: www.glpg.com
