| NCT01229319 ↗ | Imiquimod 3.75% Cream in Combination With Cryotherapy in the Treatment of Hypertrophic Actinic Keratoses | Unknown status | Graceway Pharmaceuticals, LLC | Phase 4 | 2010-10-01 | Actinic keratoses (AK) are common cutaneous lesions associate with chronic ultraviolet radiation exposure. While most authorities consider AK as a pre-malignant lesion, some consider it as an incipient squamous cell carcinoma (SCC). In addition, the skin around clinically obvious AK lesions has been subject to the same chronic ultraviolet exposure, resulting in genetic damage and mutations, resulting in "field cancerization." Subclinical AKs may progress to clinical AKs, or even de novo invasive SCCs. Among the current therapies for the treatment of AK are excisional surgery, cryosurgery, electrodessication and curettage, topical chemotherapy and light therapies. With cryotherapy, treated lesion clearance rates at 3 months post-treatment after double-freeze thaw cryotherapy has been reported to be around 76-88%; Overall lesion clearance rate at approximately 5 months post-cryosurgery has been reported to be 35-51%. Imiquimod is a topical immune response modifier and a 5% formulation has been approved for the treatment of AKs in the US as a 2x/week for 16 week regimen and in Europe as a 3x/week for 4 week regimen for 1 or 2 courses of therapy. Topical imiquimod treatment may also reduce subclinical lesions in the treatment area, resulting in fewer "new" AK lesions developing over the same period of time when compared to focal treatment. In a comparison of cryosurgery versus imiquimod for the treatment of AKs, Krawtchenko et al reported initial complete clearance rates of 68 and 85% by clinical assessment, respectively. However, the treatment field sustained clearance rate was 4% versus 73%, respectively. Tan et al reported that while application of imiquimod or vehicle following cryosurgery resulted in comparable target AK clearance rates at 12 weeks of 79% versus 76%, respectively, the imiquimod group had fewer total AKs and fewer subclinical AKs. Imiquimod cream at a concentration of 3.75% has been found in Phase 3 studies to be superior to placebo cream with respect to clearance of AKs using a regimen of up to 2 packets (250 mg of cream per packet, 500 mg total) applied daily to the entire face (approximately 200 cm2) for two 2-week treatment cycles separated by a 2-week no-treatment period. This study aims to examine the benefit of cryotherapy in combination with imiquimod 3.75% compared to cryotherapy alone. |

| NCT01502020 ↗ | A Bioequivalence Study With Clinical Endpoints Comparing Generic Imiquimod Cream, 3.75% and Zyclara™ (Imiquimod) Cream, 3.75% in Subjects With Actinic Keratoses | Completed | Actavis Mid-Atlantic LLC | N/A | 2011-02-01 | Zyclara™ (imiquimod) Cream, 3.75% is approved by the FDA for the treatment of actinic keratoses on the full face or balding scalp. Zyclara is applied once daily for two, 2-week treatment cycles separated by a 2-week no treatment applied interval. A generic imiquimod cream, 3.75% has been developed by Actavis Mid-Atlantic LLC for the topical treatment of clinically typical, visible or palpable actinic keratoses (AK) of the full face or balding scalp. The current clinical study is designed to evaluate the therapeutic equivalence of this formulation with the currently marketed Zyclara™ (imiquimod) cream, 3.75% formulation (Graceway Pharmaceuticals LLC). |
| NCT01686152 ↗ | Study Comparing Imiquimod Cream, 3.75% to Zyclara® (Imiquimod) Cream, 3.75% in the Treatment of Actinic Keratosis | Completed | Teva Pharmaceuticals USA | Phase 3 | 2012-09-01 | To determine the comparability of the safety and efficacy of Imiquimod Cream, 3.75% and Zyclara (imiquimod) Cream, 3.75% (the reference listed drug) in subjects with actinic keratosis (AK) of the face or balding scalp. It will also be determined whether the efficacy of each of the two active treatments is superior to that of the Vehicle cream. |
| NCT01788007 ↗ | Clinical Study to Evaluate the Bioequivalence of Two Imiquimod Cream 3.75% Formulations in Patients With Actinic Keratosis. | Completed | Taro Pharmaceuticals USA | Phase 1 | 2013-01-01 | The objective of this study is to compare the relative efficacy and safety of the test formulation Imiquimod 3.75% Topical Cream to the marketed formulation Zyclara® (imiquimod) 3.75% Topical Cream in the treatment of actinic keratosis. Both the test and reference formulations will also be compared to a placebo cream to test for superiority. |
| NCT02120898 ↗ | A Study to Evaluate the Safety and Efficacy Imiquimod Cream, 2.5% in Participants With Actinic Keratoses | Completed | Actavis Inc. | Phase 3 | 2013-10-10 | The purpose of this study it so compare the safety and efficacy profiles of a generic imiquimod 2.5% cream to the reference listed Zyclara® (imiquimod) cream in the treatment of actinic keratosis (AK). |
