PURPOSE This study tested the hypothesis that topical Toll-like receptor (TLR) 7 agonist imiquimod promotes antitumor immunity and synergizes with other treatments in a model of skin-involving breast cancer. EXPERIMENTAL DESIGN TSA mouse breast carcinoma cells were injected s.c. into syngeneic mice. Imiquimod 5% or placebo cream was applied topically on the shaved skin overlying tumors three ...
The low-molecular-weight imidazoquinolinamine derivative, 1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-4-amine (imiquimod, previously described as R-837), induced alpha-interferon (IFN-alpha) in mice. IFN induction was identified at oral doses as low as 3 mg/kg. The 10% lethal dose for daily treatment with imiquimod was 200 mg/kg. Oral treatment with 30 mg/kg imiquimod once every three days sig...
Imiquimod is a synthetic compound with antitumor properties; a 5% cream formulation is successfully used to treat skin tumors. The antitumor effect of imiquimod is multifactorial, although its ability to modulate immune responses by triggering TLR7/8 is thought to be key. Among the immune cells suggested to be involved are plasmacytoid DCs (pDCs). However, a direct contribution of pDCs to tumor...
BACKGROUND Pulsed dye laser (PDL) is the gold standard for treatment of port-wine stain (PWS) birthmarks but multiple treatments are required and complete resolution is often not achieved. Posttreatment vessel recurrence is thought to be a factor that limits efficacy of PDL treatment of PWS. Imiquimod 5% cream is an immunomodulator with antiangiogenic effects. OBJECTIVE We sought to determine...
BACKGROUND Imiquimod is currently approved for the treatment of genital warts and has been shown to decrease recurrences of genital herpes in the guinea pig model of genital herpes. Therefore, we evaluated the safety and potential of topical imiquimod to decrease the rate of recurrence in humans with a history of recurrent herpes labialis. METHODS Forty-seven subjects with recurrent herpes la...
BACKGROUND The incidence of nonmelanoma skin cancer, basal cell carcinomas (BCCs), and squamous cell carcinomas (SCCs) is increasing, representing a major medical and economic problem. Imiquimod, a topical small-molecule immune response modifier, has shown efficacy toward BCC and actinic keratoses in clinical trials. Imiquimod acts both indirectly, via cytokine-mediated stimulation of cellular ...
PURPOSE We questioned whether the vaccine adjuvant combination of TLR-7 ligand agonist, imiquimod, with granulocyte macrophage colony-stimulating factor (GM-CSF) would result in enhanced dendritic cell recruitment and activation with increased antigen-specific immunity as compared with either adjuvant used alone. EXPERIMENTAL DESIGN The adjuvant effects of GM-CSF and imiquimod were studied in...
BACKGROUND Current treatments for cutaneous leishmaniasis are limited by their toxicity, high cost, and discomfort and the emergence of drug resistance. New approaches, including combination therapies, are urgently needed. We performed a double-blind, randomized trial of therapy with parenteral antimony plus topical imiquimod, an innate immune-response modulator, versus therapy with antimony al...
BACKGROUND There are numerous therapeutic modalities available for treatment of molluscum contagiosum. However, the ablative modalities are painful and not suitable for children. AIM We aimed to evaluate and compare the safety and efficacy of 2 of the painless modalities, viz., 5% imiquimod cream and 10% potassium hydroxide (KOH) solution, in the treatment of molluscum contagiosum. METHODS ...
BACKGROUND Surgical approaches are the standard treatment for extramammary Paget disease (EMPD), but nonsurgical modalities may be preferred and more appropriate for some patients. Topical administration of imiquimod cream, 5%, has improved or resolved in situ EMPD (n = 21), but treatment failures (n = 6) have also been reported. OBSERVATIONS We treated an elderly patient with initial biopsy-...
