Safety of the Acne mRNA Vaccine in Adolescents 12 to 17 Years of Age With Moderate to Severe Acne

The purpose of this study is to assess the safety profile of intramuscular injections of the Acne mRNA vaccine at 3 dose levels compared with placebo in 12 to 17 years old participants with moderate to severe acne. An early safety data review (ESDR) will be conducted after each subcohort has completed an injection round; enrollment of the next higher dose level subcohort or progression of a subcohort to the subsequent injection round will only proceed if no safety concerns are identified. This sequential process will allow a cautious approach to vaccine injection in the adolescent population. Study details are as follows: * Before being enrolled in the study, participants complete a 4-week (ie, 1-month) screening period during which they will be called over the telephone approximately in the middle of the screening period to check they are not using prohibited medications and to remind them about the facial hygiene requirements. * Once the screening period has been completed, the study duration will be up to 13 months for each participant * Participants will be invited to a long-term extension study through a separate protocol.

Comparative Effectiveness Study of Spironolactone Versus Doxycycline for Acne

Acne is common illness of adolescents and young adults which is associated with substantial morbidity. While topical treatments are often sufficient for mild acne, moderate to severe acne often requires treatment with systemic medications such as oral antibiotics, hormonal therapies such spironolactone, and isotretinoin. Sebum overproduction is fundamental to the pathogenesis of acne with associated disordered keratinization and subsequent microbial colonization and inflammation resulting in the clinical manifestations of acne. Given the influence of hormones on sebum production, therapies that address these underlying hormonal factors such as spironolactone and oral contraceptive pills represent an underutilized treatment option for women with acne and could help decrease the use of long-term oral antibiotics in this patient population. The purpose of this trial is to evaluate the comparative effectiveness of spironolactone versus doxycycline hyclate (tetracycline class antibiotic) for women with acne.

Treatment will be administered via injections to acne-scarred areas on one side of the face. The untreated side will be treated after the follow-up period. Outcomes will be evaluated over a twelve-month period using investigator clinical assessments, patient self-evaluation and VISIA skin analysis system to monitor changes in scar severity and overall skin quality.

Role of Akkermansia Muciniphila in Acne Vulgaris

The project explores the use of Pendulum's Glucose Control, which contains a unique combination of probiotics, including Akkermansia muciniphila, Clostridium beijerinckii, Anaerobutyricum hallii, Clostridium butyricum, and Bifidobacterium infantis, to treat acne by improving gut health and reducing inflammation. These probiotic strains work synergistically to enhance the gut's protective barrier, lower harmful substances such as lipopolysaccharides, and increase the production of beneficial compounds like short-chain fatty acids, which can help modulate immune response and inflammation associated with acne. By integrating this probiotic combination into treatment strategies, the approach aims to offer a natural and effective solution for clearer skin. Additionally, the project seeks to investigate the correlation between postprandial glucose spikes and acne flare-ups. Continuous glucose monitoring (CGM) will be employed to track blood glucose fluctuations following meals, providing valuable insights into the potential link between metabolic responses and acne severity. This comprehensive approach aims to enhance understanding of how gut health, inflammation, and metabolic factors interact in the context of acne management.

Skin Inflammation in (Peri)Menopause: A Probiotic Intervention Proof of Concept Trial

This study will explore whether a daily probiotic drink containing Lactobacillus casei Shirota (LcS) can help improve immune function and reduce inflammation in women going through the menopausal transition. Hormonal changes during this stage of life can affect the immune system, gut health, and skin, sometimes leading to increased inflammation or conditions such as eczema, acne or rosacea. Participants will consume either a low-sugar LcS probiotic drink or a skimmed milk control drink every day for eight weeks. The study will assess markers of immune ageing, inflammation, skin health, wellbeing, and hormone levels. The results will help determine whether a safe, non-hormonal probiotic approach may support immune and skin health during the menopausal transition.

Photodynamic Therapy With Topical Application of a Zn(II) Phthalocyanine (RLP068/Cl) and Red Light for the Treatment of Moderate-to-severe Acne Vulgaris

This pilot clinical study will evaluate the safety, tolerability, and effectiveness of a novel photodynamic therapy (PDT) for moderate-to-severe acne vulgaris. PDT combines a topical photosensitizing gel with red light to treat acne lesions. The gel to be used in this study, called RLP068/Cl (a zinc phthalocyanine compound), has demonstrated antimicrobial, anti-inflammatory, and sebosuppressive effects in laboratory studies. A total of 10 patients with moderate-to-severe acne on the face will be enrolled. RLP068/Cl 0.3% gel will be applied topically for 30 minutes under occlusion, followed by 8 minutes of red LED light exposure. Treatments will be performed twice weekly, with the total number of sessions individualized based on clinical response. Acne severity will be assessed using the Global Acne Grading System (GAGS). Pain levels will be recorded after each session using a visual scale, and patient satisfaction will be evaluated at the end of the treatment cycle. The goal of the study is to determine whether RLP068/Cl-PDT is a safe, well-tolerated, and effective non-antibiotic treatment option for patients with moderate-to-severe acne vulgaris who may not respond to or tolerate conventional therapies.

Creation of a Monocentric Cohort of Patients Treated for Acne at the Nantes University Hospital

With 24 million results associated with Google's searchon keywords "severe acne", Pr Dreno's team understand better thatthis disease, which affects many French people, is a real concern of Public Health and not a "forced evil" of the adolescent period, which will eventually resolve itself. Acne does not affect the vital prognosis, but its psychosocial impact is major and should not be underestimated. Paradoxically, despite the high prevalence of acne, few quality epidemiological studies have been published. Physicians are often helpless when faced with patients' questions. They often need a lot of explanations, especially on the factors aggravating this dermatosis, which greatly affects their quality of life. This cohort, the first of its kind in France, will determine the predictive factors of therapeutic response, endogenous and environmental factors impacting on the severity of acne assess the quality of life and psychological impact of acne patients, determine the patient's course of care and the associated costs. Pr Dreno's team will also build up a bio collection (bacteriological samples).

Topical Application of Engineered Lactobacillus Reuteri With a Zinc Sulfate-Tannic Acid MPN Coating for Acne

A growing body of evidence suggests that the development and progression of acne are closely linked to an imbalance in the skin's microbial community. Compared to healthy skin, the composition and function of the microbiota in acne lesions are significantly altered. This microbial imbalance is believed to drive the formation and recurrence of acne through mechanisms such as triggering abnormal inflammatory responses and compromising the skin barrier. An in-depth exploration of the interaction between acne and the skin microbiome not only offers new perspectives for understanding the root causes of the disease but also lays the groundwork for developing novel treatment strategies aimed at modulating the microbiota. Therefore, identifying innovative approaches that integrate acne treatment with the regulation of microbial balance holds significant clinical and social value. Although existing acne treatments have made progress, research focusing on interventions that regulate the local skin microecology through probiotics remains relatively limited. This study aims to explore a new strategy based on skin microecological modulation. Investigators are using a common probiotic-Lactobacillus reuteri-and applying an engineering modification with a special coating formed by zinc sulfate and tannic acid (MPN coating). This modification is intended to enhance the bacterium's survival and colonization on the skin, thereby more effectively regulating the local microbiota and reducing inflammation. This study is a rigorous scientific clinical trial designed as randomized, double-blind, and controlled. Eligible participants will be randomly assigned to one of four groups, receiving either the engineered Lactobacillus reuteri cream, the plain Lactobacillus reuteri cream, a simple moisturizing cream (placebo), or an already-marketed effective cream (tretinoin cream). The treatment will last for 2 weeks, followed by an 8-week observation period. Efficacy and safety will be evaluated through professional assessments. Our goal is to scientifically evaluate the safety and efficacy of this new therapy, hoping to provide a potential new treatment option for individuals with acne and explore new pathways for improving skin health.

Experience With Topical Acne Treatment

Acne is a chronic condition that typically requires the use of multiple medications.1 Medication adherence is especially challenging for patients with chronic diseases and often decreases over time, especially for those using topical medications.1 Nonadherence can result in multiple negative effects including treatment failure, increased healthcare costs, and decreased quality of life. Primary nonadherence refers to problems acquiring and starting treatment. Challenges to this form of nonadherence include a lack of knowledge, misunderstanding of usage, poor communication with provider, increased cost, and fear of side effects.2 Secondary nonadherence refers to when the patient does not use the medication as prescribed. Hurdles to secondary nonadherence include delayed results, increased complexity of treatment plan, adverse effects, busy lifestyle, and inconvenience.2

Expert Consensus on the Use of Isotretinoin in Acne Vulgaris: A Delphi Study

This study is a Delphi-based expert consensus project designed to establish evidence-informed, practical recommendations for the use of isotretinoin in acne vulgaris.
