Recommended Usage and Dosage of Otezla (Apremilast) for Plaque Psoriasis and Psoriatic Arthritis

Otezla (apremilast) is recommended at a maintenance dose of 30 mg twice daily for adults with moderate to severe plaque psoriasis or psoriatic arthritis, following a 5-day titration schedule to minimize gastrointestinal side effects. 1

Indications

  • Otezla is indicated for the treatment of adult patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy 1
  • Otezla is also indicated for the treatment of adult patients with active psoriatic arthritis 1

Dosing Schedule

Standard Dosing Titration

The recommended 5-day titration schedule is as follows:

  • Day 1: 10 mg in the morning
  • Day 2: 10 mg in the morning and 10 mg in the evening
  • Day 3: 10 mg in the morning and 20 mg in the evening
  • Day 4: 20 mg in the morning and 20 mg in the evening
  • Day 5: 20 mg in the morning and 30 mg in the evening
  • Day 6 and thereafter: 30 mg twice daily (maintenance dose) 1

Special Populations

  • For patients with severe renal impairment (creatinine clearance <30 mL/min): reduce dose to 30 mg once daily 1, 2
  • For patients with severe renal impairment, use only the morning (AM) schedule during the titration period and skip the evening (PM) doses 1

Administration

  • Otezla can be administered without regard to meals 1
  • Do not crush, split, or chew the tablets 1

Efficacy

Plaque Psoriasis

  • In clinical trials, approximately 33% of patients achieved PASI-75 (75% reduction in Psoriasis Area and Severity Index) at week 16 3
  • Efficacy is maintained through 52 weeks in patients who continue treatment 3, 4
  • Real-world studies suggest potentially higher response rates in patients with lower baseline disease severity 5

Psoriatic Arthritis

  • Apremilast improves signs and symptoms in both DMARD-naïve and DMARD-experienced patients with active psoriatic arthritis 6
  • Improvements in enthesitis, dactylitis, physical function, and fatigue have been observed 6
  • Early onset of efficacy can be seen as early as week 2 6

Special Sites of Psoriasis

  • Apremilast is effective for difficult-to-treat areas including nail, scalp, and palmoplantar psoriasis 5
  • Significant improvements in pruritus can be seen as early as week 2 6

Monitoring and Safety

Common Adverse Effects

  • The most common adverse effects include:
    • Diarrhea (17.3%) 5
    • Nausea (15.7%) 5
    • Upper respiratory tract infections (15.5%) 5
    • Headache (6.3-9.0%) 5

Precautions

  • Monitor for depression and suicidal thoughts, especially in patients with a history of depression 1, 2
  • Monitor weight regularly; consider discontinuation if weight loss exceeds 5% of baseline 2
  • Patients 65 years or older may be at higher risk for complications from severe diarrhea, nausea, or vomiting 1
  • Consider dose reduction or suspension if patients develop severe gastrointestinal symptoms 1

Drug Interactions

  • Avoid use with strong cytochrome P450 inducers (e.g., rifampin, phenobarbital, carbamazepine, phenytoin) as they may decrease efficacy 2, 1

Laboratory Monitoring

  • No routine laboratory monitoring is required 6
  • Laboratory screening and monitoring can be considered on an individual basis 2

Combination Therapy

  • There is limited evidence supporting the combined use of apremilast with other systemic or phototherapy treatments for psoriasis 2
  • In the treatment algorithm for psoriatic arthritis, oral NSAIDs are generally preferred over apremilast as first-line therapy 2
  • TNF inhibitor biologics are generally preferred over apremilast for psoriatic arthritis 2
  • Small studies suggest apremilast can be safely combined with biologic agents in patients not responding adequately to biologics alone 7

Pregnancy Considerations

  • Use during pregnancy only if the benefit justifies the potential risk to the fetus 2

Clinical Pearls

  • Apremilast offers the convenience of oral administration without the need for laboratory monitoring 6
  • The 5-day titration schedule is designed to reduce gastrointestinal side effects 1
  • For patients who prefer oral treatment and are willing to accept a slower onset of skin clearance, apremilast is an appropriate choice 2
  • Gastrointestinal side effects typically occur within the first few weeks of treatment and generally improve over time 1
