Amolimogene bepiplasmid, a DNA-based therapeutic encoding the E6 and E7 epitopes from HPV, for cervical and anal dysplasia.
MGI Pharma Biologics is developing amolimogene bepiplasmid as a potential therapy for HPV-associated diseases, including cervical dysplasia. Amolimogene bepiplasmid is a polymer-encapsulated DNA vaccine consisting of a plasmid expressing a chimeric peptide comprising immunogenic hybrid epitopes from HPV-16 and HPV-18 E6 and E7 proteins and an HLA-DRalpha intracellular trafficking peptide. In phase I and I/II clinical trials of ZYC-101 (the precursor of amolimogene bepiplasmid containing a single epitope from HPV-16 E7) in patients with cervical dysplasia and patients with anal dysplasia, ZYC-101 produced significant histological regression and was safe and well tolerated. Results from this trial led to a phase II clinical trial of amolimogene bepiplasmid in patients with cervical dysplasia. This phase II trial demonstrated that treatment with amolimogene bepiplasmid resolution of disease was not significantly superior to placebo except in the predefined group of women who were less than 25 years of age. A phase II/III clinical trial was ongoing at the time of publication examining amolimogene bepiplasmid in this patient population.
