Study design (phase 3 trials): The safety and
efficacy of DUOBRII Lotion were assessed in 2 prospective, multicenter, randomized, double-blind,
phase 3 clinical trials in 418 adult patients with moderate-to-severe plaque psoriasis. Patients
were treated with DUOBRII Lotion or vehicle, applied once daily and evaluated at 2, 4, 6, 8 weeks
(primary endpoint), and post treatment at 12 weeks.1
Study design (phase 2 trial): A multicenter, double-blind,
randomized, parallel-group phase 2 study to assess the safety, tolerability, and efficacy of DUOBRII
Lotion in 212 patients with a clinical diagnosis of moderate-to-severe psoriasis. Patients were
treated with DUOBRII Lotion, halobetasol 0.01%, tazarotene 0.045%, or vehicle, and evaluated at 2,
4, 6, 8 weeks (primary endpoint), and post treatment at 12 weeks. However, there was no prespecified
statistical procedure controlling for Type 1 error rate (false positive rate).11
Indication
DUOBRII® (halobetasol propionate and
tazarotene) Lotion, 0.01%/0.045%, is indicated for the topical treatment of plaque psoriasis in
adults.
Important Safety Information
Contraindication
DUOBRII Lotion is contraindicated in pregnancy.
Warnings and Precautions
- Women of child-bearing potential should be warned of the potential risk of fetal harm from
DUOBRII and use adequate birth-control. A negative result for pregnancy should be obtained
within 2 weeks prior to treatment. If the patient becomes pregnant during treatment,
discontinue
DUOBRII Lotion and advise patient of the potential hazard to the fetus.
- DUOBRII Lotion has been shown to suppress the hypothalamic-pituitary-adrenal (HPA) axis
during
or after treatment and may require that patients be evaluated periodically during treatment.
- Predisposing factors for HPA axis suppression include: use of more potent corticosteroids,
use
on large areas, use under occlusive dressings, use on altered skin barrier, concomitant use
of
other steroids, liver failure and young age.
- Systemic effects of topical corticosteroids may also include Cushing’s syndrome,
hyperglycemia, and glucosuria.
- Local adverse reactions may include atrophy, striae, telangiectasias, folliculitis and
contact
dermatitis. If these effects occur, discontinue until the integrity of the skin has been
restored. Do not resume treatment if contact dermatitis is identified. DUOBRII Lotion should
not
be used on eczematous skin, as it may cause severe irritation.
- Avoid exposure to sunlight, sunlamps and weather extremes. Patients with sunburn should be
advised not to use DUOBRII Lotion until fully recovered. DUOBRII Lotion should be
administered
with caution if the patient is also taking drugs known to be photosensitizers because of the
increased potential for photosensitivity.
- Topical corticosteroids may increase the risk of cataracts and glaucoma; advise patients to
report any visual symptoms and refer to an ophthalmologist if needed.
Adverse Events
- The most common adverse events in clinical trials were contact dermatitis (7%), application
site
pain (3%), folliculitis (2%), skin atrophy (2%), and excoriation (2%).
