Ustekinumab: A human monoclonal antibody for the treatment of plaque psoriasis
March 1st 2009Ustekinumab is a novel investigational human monoclonal antibody (mAb) that is pending approval for the treatment of plaque psoriasis. Subcutaneous administration of ustekinumab has demonstrated efficacy in both phase 2 and 3 trials.
Case of PML reported in efalizumab-treated patient
October 14th 2008Genentech informed healthcare professionals that a 70-year-old patient who has been treated with efalizumab (Raptiva) for chronic psoriasis for >4 years has developed progressive multifocal leukoencephalopathy (PML), a rare, progressive disease of the central nervous system that is usually fatal.
Isotretinoin may trigger IBD in subgroup of patients
October 1st 2006A review of adverse event data associated with the synthetic vitamin A retinoid isotretinoin between 1997 and 2002 suggests that the acne treatment is a "probable" cause of inflammatory bowel disease (IBD) and may precipitate its presentation within a certain subset of patients who are either predisposed to the disease or have subclinical symptoms.
Lower oral retinoid dose effective for psoriasis
June 1st 2006A lower dose of the oral retinoid acitretin is effective for moderate-to-severe psoriasis and can minimize adverse effects, according to a study presented at the 64th Annual Meeting of the American Academy of Dermatology in San Francisco. Current practice is to administer the maximal tolerated dose of 25 mg to 50 mg acitretin daily.
New monoclonal antibody effective for plaque psoriasis
June 1st 2006CNTO 1275, an anti-IL12p40, maintains efficacy in clearing plaque psoriasis for up to 24 weeks after 1 dose, according to results of a phase 2 study presented by researchers at the 64th Annual Meeting of the American Academy of Dermatology in San Francisco. The subcutaneously injected agent targets both interleukin 12 and 23, two key cytokines in type 1 immune responses, said study author Gerald G. Krueger, MD, of the department of dermatology, University of Utah Health Sciences Center, in Salt Lake City, Utah.
Imiquimod for superficial basal cell carcinoma
August 1st 2004Although the mechanism of action of imiquimod is unknown, an open-label study suggests that the drug may act by increasing the filtration of lymphocytes, dendritic cells, and macrophages into the tumor lesion. Imiquimod was approved on July 14, 2004, for an expanded indication to include the treatment of biopsy-confirmed, primary superficial basal cell carcinoma (sBCC) in immunocompetent adults.
Efalizumab: A new biologic therapy for the control of chronic plaque psoriasis
January 4th 2004Efalizumab (Raptiva, Genentech/Xoma) is a humanized monoclonal antibody of CD11a that exerts its effect through the blockade of the interaction between leukocyte function-associated antigen-1 (LFA-1) and intercellular adhesion molecule-1 (ICAM-1). FDA recently granted approval for efalizumab in the treatment of chronic moderate-to-severe plaque psoriasis in adults aged 18 years and older. Efalizumab does not achieve clinical response rates equal to cyclosporine or methotrexate, but it lacks the systemic organ toxicities of these agents and is associated with a more rapid onset of action (significant improvements in Psoriasis Area and Severity Index [PASI] response after 2 doses). In addition, efalizumab will likely compete with another approved biologic, alefacept, and off-label use of 2 other biologics currently on the market, etanercept and infliximab. At this time, until further studies comparing efalizumab to other drugs indicated for the treatment of psoriasis are completed and post-marketing surveillance is conducted, the agent?s place on the formulary remains unclear.
Alefacept: A T-cell-specific immunosuppressant to treat moderate to severe plaque psoriasis (PDF)
July 1st 2002Alefacept (Amevive) is the first immunosuppressive agent directed specifically at inhibiting the activation of, and possibly killing, T cells, which are involved in the cascade of events leading to psoriatic plaque formation and inflammation. In May, an FDA advisory committee recommended alefacept for approval as a first-line therapy against moderate to severe plaque psoriasis. The authors of this Focus article review the clinical characteristics of alefacept as well as make comparisons with other systemic drugs currently used to treat chronic psoriasis and the likely biologic competitors etanercept and infliximab.
Atopic Dermatitis: Disease Overview and the Development of Topical Immunomodulators (PDF)
May 1st 2002Atopic dermatitis is a chronic, recurrent skin disease characterized by intense pruritis (itching) and inflammation. This supplement which was produced through an unrestricted educational grant from Fujisawa Healthcare, Inc. provides you with an overview of the disease and the development of Topic Immunomodulators. The views and opinions expressed in this supplement do not necessarily reflect the views of Formulary.
Biologics new and old may offer long-term management option for psoriasis
April 1st 2002An array of both existing and investigational biologic agents are showing efficacy in clearing psoriasis and may prove useful for long-term psoriasis management. So suggests a collection of studies presented at the 60th annual meeting of the American Academy of Dermatology, held recently in New Orleans.
