What do Psoriasis Endpoints Mean?

Body surface area (BSA)

National Psoriasis Foundation psoriasis.org; Accessed Oct 21, 2015.

Investigators Global Assessment

IGA has no correlation to amount of disease, only the severity of the individual plaques

Psoriasis area and severity index PASI Composite index of both extent and severity of

disease– Measures average erythema, scaling and thickness of

lesions– Weighted by area of involvement

Commonly used in clinical trials but not in clinical practice

Potency: Vehicles Matter

Traditional thinking was that drugs had to be occlusive (ointment) in order to get the best penetration and efficacy

Newer vehicles have changed our mindset Changing vehicles can affect efficacy

SIDE EFFECTS OF TOPICAL CORTICOSTEROIDS: WHAT ARE THE FACTS?

Epidermal Atrophy

Josse G, Skin Res Technol. 2009

13 healthy women. Clobetasol Propionate BID X 28 days. Optical coherence tomography. Dashed line: reference zone.

Histology showed 22% epidermal thinning after 28 days.

Dermal AtrophyTreatment with Clobetasol Propionate BID X 28 days. Demal thickness measured by ultrasound. Dashed line: reference zone.

Josse G, Skin Res Technol. 2009

12% average decrease at day 28. Thickness increased with D/C of treatment

Steroid Induced Atrophy-Prevention? Tazarotene Gel 0.1%

Taz + DD reduced atrophy by 37% Ammonium lactate (AL)

AL + CP 35% decrease, 15% decrease occluded

Calcipotriene ointment C + BP Minimized atrophy in animal model

Maintenance Therapy: Standard dosing or PRN?

OBJECTIVE: – To investigate maintenance strategies of a C/BD suspension for

the treatment of scalp psoriasis.

MATERIALS AND METHODS: – 885 patients, treat daily until clear or almost clear then

maintenance as two groups X 12 weeks total: two applications per week on-demand therapy

CONCLUSIONS: – Twice-weekly application more effective and is

associated with a lower rate of relapse. (19.5% vs 41.7%; P<.001)

Calcipotriene: Vehicle Matters Ointment (8 weeks)

– 70% marked improvement Skin irritation 10-15%– 11% clear

Cream– 50% marked improvement Skin irritation 10-15%– 4% clear

Solution– 31% marked improvement Skin irritation 1-5%– 14% clear

Calcipotriene/Betamethasoe Dipropionate Ointment: Efficacy

*Safety data for 1 year of use

Is it possible to enhance penetration with a cosmetically acceptable vehicle?

Cal/BD Ointment more efficacious than suspension but less cosmetically elegant

Cal/BD Aerosol Foam Formulation explored for enhanced efficacy + enhanced elegance.

plaque psoriasis Randomized 3:1 to receive cal/beta foam or vehicle only 1 x

Efficacy of the fixed combination C/BP in an aerosol foamVS ointment in patients with psoriasis vulgaris

Methods•A multicenter, prospective, randomized trial 2-30% BSA IGA > mild•376 patients were randomized in 3:1:3:1 ratio to receive once-daily treatment for 4 weeks

– Cal B/D aerosl foam– Cal B/D vehicle– Calcipotriene plus BDP ointment– Ointment vehicle

•Investigator-only blinded– Full double-blinding was not possible because of the difference

in formulation

Koo J J Dermatolog Treat. 2015 Oct 7:1-8. [Epub ahead of print]

35 patients with extensive psoriasis body and with total BSA of 30% (range: 15%-30%) with Cal BD 90100 qD X 4 weeks

Average 90100 aerosol foam = 62 g/wk; approximately twice the average exposure from typical Cal BD 90100 trials

None showed adrenal suppression, as indicated by a 30-minute post-stimulation cortisol level ≤18 mcg/dL at day 28

There was no evidence of an effect of Cal BD aerosol foam 90100 on calcium metabolism, based on evaluation of serum and 24-hour urinary calcium parameters

Cal BD aerosol foam 90100 was safe and well tolerated – No SAEs, discontinuation of investigational product due to AEs, or other significant AEs

were reported in this trial

Phase 2 MUSE Trial: Safety

Tazarotene Available in 0.1% and 0.05% cream

and gel Topical retinoid, Pregnancy Category X Side effects occurring in 10 to 30% of

patients: pruritus, burning/stinging, erythema, worsening of psoriasis, irritation, and skin pain

Combination with topical CS improves efficacy while minimizing SE’s

Novel Molecules in the Pipeline

In phase II trials: PDE4 inhibitor ointment Integrin inhibitor cream Jak1/Jak 3 inhibitor (tofacitinib) ointment Jak1/Jak 2 inhibitor (ruxolitinib) cream Tyrosine kinase inhibitor cream & ointment Dihydrofolate reductase inhibitor (methotrexate) proprietary vehicle

Feely MA, et al. Cutis. 2015;95:164‐168, 170.

Conclusion Cutaneous atrophy occurs commonly but is

generally reversible Vitamin D is an important addition to topical

steroid treatment– Complimentary efficacy targets– Counteracts steroid side effects

Tazarotene still hold an important place in psoriasis topical therapy

There is an active future in new molecules for topical therapy
