Ustekinumab

Molecular Formula of Ustekinumab (CAS No.815610-63-0): C₆₄₈₂H₁₀₀₀₄N₁₇₁₂O₂₀₁₆S₄₆ 

  Ustekinumab (CAS No.815610-63-0) (INN, experimental name CNTO 1275, proprietary commercial name Stelara.
  Its history as follows:
  1. In January 2007, there were 5 NIH-listed research studies involving CNTO 1275 on a multinational basis, including 3 Phase II and 2 Phase III trials. Three studies were focused on patients with psoriasis, one on psoriatic arthritis, and one on multiple sclerosis.
  2. On December 4, 2007, a Biologic License Application (BLA) with the U.S. Food and Drug Administration (FDA) was filed by Centocor and Janssen-Cilag International (collaborator) has submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMEA).
  3. On June 17, 2008, the Dermatologic and Ophthalmic Drugs Advisory Committee (DODAC) of the U.S. Food and Drug Administration unanimously recommended the approval of ustekinumab (CNTO 1275) for the treatment of adult patients with moderate to severe plaque psoriasis. The decision by the committee is non-binding and final decisions on approval of the drug are made by the FDA. The FDA approved the drug on September 25, 2009.
  4. On November 21, 2008, the European Medicines Agency’s (EMEA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for ustekinumab for the treatment of moderate to severe plaque psoriasis in adult patients who failed to respond to other systemic therapies.
  5. On December 12, 2008 the Canadian Health Authority approved the use of ustekinumab for the treatment of chronic moderate to severe plaque psoriasis in adult patients who are candidates for phototherapy or systemic the
  6. In September 2008, Centocor released result of a study comparing etanercept and ustekinumab. The entanercept group received subcutaneous injections of the drug twice weekly for 12-weeks while the ustekinumab group received 2 injections, one-month apart, of either 90 or 45 milligrams. At twelve weeks, psoriatic plaques were reduced by at least three-quarters in 68% of the low-dose ustekinumab group and 74% of the high-dose group. Both groups fared better than the etanercept group, 57% of whom saw such improvement. Dr. Alan Menter, chairman of psoriasis research at Baylor Research Institute said of the results, "now we have a drug that will be used less frequently ... with a significant increase in effectiveness. These results are as good as we've seen in psoriasis."
