The problem Molluscum Contagiosum

MOLLUSCUM BACKGROUND ETIOLOGY AND CLINICAL PRESENTATION OVERVIEW Caused by a pox virus Primarily infects children, with the highest incidence occurring in children <14 years old Highly contagious If untreated, lesions persist an average of 13 months, with some cases remaining unresolved for 2+ years Often leads to anxiety and social challenges for the patients and parents and negatively impacts quality of life Transmission Skin to skin contact Sharing of contaminated objects (e.g., clothing, towels, swimming pool toys) Diagnosis & Symptoms Typically 10 to 30 lesions 100+ lesions can be observed Lesions may be the only sign of infection and are often painless Can be diagnosed with skin biopsy to differentiate from other lesions Complications Skin irritation, inflammation, and re-infection Follicular or papillary conjunctivitis if lesions on eyelids Cellulitis Copyright © 2020 Verrica Pharmaceuticals.

DERMATOLOGISTS ARE FAMILIAR WITH API USED in Ycanth™ (VP-102) & WOULD USE IF AVAILABLE Pompei DT et al. Cantharidin Therapy: Practice patterns and attitudes of health care providers. Journal of the American Academy of Dermatology. 2013; 68(6). Survey of 400 healthcare providers, 87.7% of responders were US based dermatologists. Company survey of 40 physicians. Physicians who do not use the API of Ycanth™ (VP-102) stated inaccessibility as a primary reason why they are not using(1) Physicians reported they would use Ycanth™ (VP-102) if the cost of the drug was covered(2) ~70% 87%

Physicians are highly favorable to Ycanth (VP-102) profile Physician Qualitative research- one-hour individual interviews [n=30 Pediatricians, 13 Dermatologist, 5 Pediatric Dermatologists] Derms and Ped Derms (1) Pediatricians (1) 5.6 6.3 Efficacy Efficacy KEY REASONS TO USE IF APPROVED Convenience of administration Frustrated with not treating and having no viable options Scale of 1 (unlikely to use at all) to 7 (highly likely to use) Precise and pain free application FDA approval Fits into their current office model KEY REASONS TO USE IF APPROVED

VERRICA HAS SEVERAL POTENTIAL WAYS TO MAINTAIN EXCLUSIVITY Regulatory Exclusivity 5.5 years of exclusivity for cantharidin as API potentially available upon approval (inclusive of potential for 6 months for pediatric indication) Compounding Pharmacies If VP-102 is approved, traditional compounding pharmacies will NOT be able to continue compounding cantharidin regularly or in inordinate amounts, except under patient specific circumstances as prescribed by a physician. The FDA has the authority to regulate compounders. Improper compounding can result in monetary fines plus felony convictions in case of repeat offenses and intent to fraud/mislead. Manufacturing VP-102 has the potential to address stability issues with standard packaging and container/ closure systems True Generic Unlikely Unlikely to receive approval under an ANDA due to uniqueness from patent pending protection and significant differences likely between Ycanth™ (VP-102) and potential competitors Cannot do traditional PK/bioequivalence study (no blood level profile for Ycanth™ (VP-102) ) May require new clinical studies with new formulation and new delivery approach that shows equivalence without violating any of Verrica's IP Limited commercial CMOs with facilities for handling highly potent and highly flammable liquid products Entered into a supply agreement for naturally-sourced cantharidin; subject to specified minimum annual purchase orders and forecasts, supplier agreed that it will not supply cantharidin, any beetles or other raw material from which cantharidin is derived to any other customer in North America

OVERVIEW OF INTELLECTUAL PROPERTY PORTFOLIO KEY CLAIMS AND PATENT APPLICATIONS VALUE TO VERRICA Our specific formulation, YCANTH™ (VP-102), key safety additions and novel cantharidin formulations (PCT/US2014/052184) May prevent generics from copying our ether-free formulation or from making similar formulations Single use applicator containing cantharidin formulations (PCT/US2014/052184) May prevent generics from utilizing a single-use applicator for cantharidin that contains both a glass ampule to maintain product stability and a filter placed prior to dispensing tip, which helps increase administration accuracy and prevents direct contact with skin Specific design of our commercial applicator (PCT/US2018/036353) May prevent generics from utilizing a similar applicator Methods of use for cantharidin in the treatment of molluscum (PCT/US2018/037808 and PCT/US2018/036353) May prevent generics from a similar treatment regimen and label Methods for purifying cantharidin and analyzing cantharidin or cantharidin solutions (PCT/US2016/14139) May force generics to find alternative methodologies to produce GMP cantharidin or determine if their API or drug product is GMP compliant Methods for complete cantharidin synthesis (PCT/US2015/066487) Synthetic version would reduce risks of outside contaminants and environmental factors affecting the naturally-sourced API. May prevent generics competing with a synthetic version of cantharidin Any patents issued from our applications are projected to expire between 2034 and 2039, excluding any patent term adjustment and patent term extensions 1 2 3 4 5

Our Opportunity in Common Warts

VERRUCA VULGARIS (COMMON WARTS) ETIOLOGY AND CLINICAL PRESENTATION OVERVIEW Caused by human papilloma virus (HPV) Infects patients of all ages Persistent infection, highly refractory Typically 2-5 lesions No FDA approved drug for the treatment of common warts Transmission Skin to skin contact Touching of contaminated objects Diagnosis & Symptoms Dome shaped flesh-colored lesions commonly on the hands, fingers, knees or elbows Lesions may occur in groups or in a linear pattern Lesions can cause considerable pain and discomfort, may spread with skin trauma, and can be itchy Complications Scarring may occur Dyspigmentation of affected areas Bacterial superinfection of lesions Irritation, pain, and redness of surrounding skin Copyright © 2020 Verrica Pharmaceuticals.
