Psoriasis Drug of Amgen and AstraZeneca conquered blockbuster Stelara

 

Clinical courses

(12th November, 2014); Brodalumab, a novel psoriasis drug from colloboration of Amgen and Astrazeneca shown superior results in compare to Stelara® (ustekinumab) in head to head trials. The trial conducated on moderate-to-severe plaque psoriasis which met its primary endpoints when compared with both Stelara and placebo at week 12. Brodalumab was shown to be superior to Stelara on the primary endpoint of achieving total clearance of skin disease, as measured by the Psoriasis Area Severity Index (PASI 100).

Stelara of Johnson & Johnson earned $543 million in last quarter for company and had major contribution in company's growth. New research from Amgen and Astrazeneca looks like to bestow healthy competition.

Psoriasis is a serious, chronic inflammatory disease that causes raised, red, scaly patches to appear on the skin, typically affecting the outside of the elbows, knees or scalp, though it can appear on any location. Approximately 125 million people worldwide have psoriasis and 80 percent of those patients have plaque psoriasis.

In April 2012, Amgen and AstraZeneca formed a collaboration to jointly develop and commercialize five monoclonal antibodies from Amgen’s clinical inflammation portfolio. With oversight from joint governing bodies, Amgen leads clinical development and commercialisation for brodalumab (Phase III for moderate-to-severe plaque psoriasis and psoriatic arthritis, Phase II for asthma).

Results showed that 36.7 percent of patients in the brodalumab 210 mg group, 27 percent of patients in the brodalumab 140 mg group, 18.5 percent of patients in the Stelara group and 0.3 percent of patients in the placebo group achieved total clearance of skin disease (PASI 100). In addition, 85.1 percent of patients in the brodalumab 210 mg group, 69.2 percent of patients in the brodalumab 140 mg group, 69.3 percent of patients in the Stelara group and 6 percent of patients in the placebo group achieved PASI 75.

Brodalumab is a novel human monoclonal antibody that binds to the interleukin-17 (IL-17) receptor and inhibits inflammatory signaling by blocking the binding of several IL-17 ligands to the receptor. By stopping IL-17 ligands from activating the receptor, brodalumab prevents the body from receiving signals that may lead to inflammation. The IL-17 pathway plays a central role in inducing and promoting inflammatory disease processes. In addition to moderate-to-severe plaque psoriasis (Phase III), brodalumab is currently being investigated for the treatment of psoriatic arthritis (Phase III) and asthma (Phase II).
