Phase 1
Not yet recruiting
Conditions
Acne
Interventions
Registration Number
NCT07013747
Lead Sponsor
Sanofi Pasteur, a Sanofi Company
Brief Summary

The purpose of the VBE00009 study is to evaluate the safety, efficacy and immunogenicity of 2 administrations of the Acne mRNA vaccine candidate at single dose level in participants aged 18 to 45 years with mild acne. This study will consist of a Sentinel Cohort and a Main Cohort, with the Sentinel Cohort assessing the safety in a stepwise manner.

Inclusion Criteria
  • Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, and laboratory tests as judged by the investigator

  • Clinical diagnosis of mild facial acne vulgaris with:

    • IGA score of mild (grade 2 on the 5-grade IGA scale) AND
    • between 10 to 24 non-inflammatory lesions (ie, open and closed comedones) AND
    • between 5 to 19 inflammatory lesions (ie, papules and pustules) AND
    • no nodulocystic lesions (ie, nodules and cysts)
Exclusion Criteria

Participants are excluded from the study if any of the following criteria apply:

  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within 6 months prior to the first study intervention administration; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
  • Known systemic hypersensitivity to any of the study intervention components (eg, polyethylene glycol [PEG], polysorbate); history of a life-threatening reaction to the study interventions used in the study or to a product containing any of the same substances; any allergic reaction (eg, anaphylaxis) after administration of mRNA coronavirus disease 2019 (COVID 19) vaccine
  • Previous history of myocarditis and/or pericarditis and/or myopericarditis
  • Skin pathology or condition that, in the investigator's opinion, could interfere with the evaluation of the study intervention or requires use of interfering topical, systemic, or surgical therapy
  • Excessive facial hair, facial tattoos, facial skin disorders, skin reactions that may interfere with the study assessments in the investigator's opinion (including - but not limited to - actinic keratosis, eczema, psoriasis, seborrheic dermatitis, rosacea, acute or recent sunburn) or skin infection
  • Receipt of immune globulins, blood or blood-derived products in the past 3 months
  • Self-reported or documented seropositivity for human immunodeficiency virus (HIV), hepatitis B virus, or hepatitis C virus
