VYN201: Vitiligo Disease / Market Overview
Vitiligo – Disease Overview An acquired disorder of dermatologic pigmentation with high impact on self - esteem 14 Pathophysiology & Clinical Presentation • Vitiligo is a depigmenting skin disorder characterized by the loss of melanocytes, which causes typical non - scaly, chalky - white macules • Pathogenesis is classified as autoimmune in nature ; the disease is associated with a culmination of genetic and environmental factors with metabolic, oxidative stress, and cell detachment abnormalities • Vitiligo can be classified as segmental or non - segmental; segmental presentation appears unilaterally , while non - segmental presents bilaterally and occasionally mucosally (i.e., around the mouth) • Characteristic amelanotic lesions, while physically harmless, tend to be psychologically devastating Source: UptoDate ; Bergqvist. Dermatol. 2020;236:571 - 592; Karagaiah . Expert Opin Emerg Drugs. 2020;25(1):7 - 24
Vitiligo – Treatment Paradigm Only one drug currently approved; Treatment is dominated by non - specific therapeutics 15 Current Treatment Paradigm 1L Corticosteroids Phototherapy Topical Calcineurin Inhib . Excimer Laser 2L Phototherapy + Combo Agent(s) 3L+ Surgery Depigmentation Therapy Treatment modality is dependent on disease area (segmental vs. non - segmental) as well as activity (controlled vs. uncontrolled); patients typically receive NBUVB phototherapy, excimer laser procedure, or an oral / topical anti - inflammatory agent in the 1L 1L agents are often used in combination in the 2L to enhance disease control Surgeries include skin tissue / cellular grafting and hair follicle transplant, often technically challenging and costly ; depigmentation therapy is a less common FDA - approved modality for cosmetic improvement Vitiligo Key Unmet Need Current vitiligo treatment is dominated by non - specific therapeutics with only one drug recently approved with a black box warning A targeted, safe and more efficacious treatment option is needed that lowers the disease recurrence rate and is effective for all skin tones / scar types Source: UptoDate ; Bergqvist.

FMX114: Potential for a series of firsts in the treatment of atopic dermatitis 43 FMX114 has the potential to be the: • 1 st topical combination product for the treatment of atopic dermatitis • 1 st topical product containing a sphingosine 1 - phosphate receptor modulator (S1PRM) • S1PRM’s that are in development are orally delivered and have specific systemic adverse events to overcome but have been shown to be effective in AD • 1 st prescription topical product to be formulated in a silicon elastomer formulation • Using in - house capabilities, FMX114 is designed to optimally deliver both APIs to the site of inflammation in the skin and reduce systemic exposure • Silicon elastomer gel is an elegant, non - irritating formulation and applies with a cooling effect on the skin • Formulation is non - greasy and absorbs rapidly into the skin

FMX114 Phase 1b/2a Results Summary 51 x FMX114 drug effect and proof - of - concept established • On target PK and safety profile met • Statistically significant efficacy results at weeks 1, 2 and 3; Primary efficacy endpoint at week 4 not met but numerically superior • Continued effect demonstrated through week 6 (OLE) • Subanalyses show higher ADSI scores at baseline correlated with improved overall treatment effect separation of FMX114 vs. vehicle x Analyses suggests Phase 2a results confounded by over - enrollment of subjects with mild disease severity: 1. Mean ADSI scores at baseline of 6.6 - 6.9 suggests over - enrollment of subjects with mild disease severity, potentially resulting in elevated vehicle effect in the full study population (inclusion criteria was mean ADSI score of ≥ 6 and ≤ 12) 2.
