Category C

Clinical Essentials

OTEZLA
HUMIRA
Mechanism of Action
OTEZLA

Apremilast is a small molecule inhibitor of phosphodiesterase 4 (PDE4), which increases intracellular cyclic AMP (c AMP) levels. Elevated c AMP modulates inflammatory cytokine production, reducing TNF-α, IL-17, IL-23, and other pro-inflammatory mediators.

HUMIRA

Tumor necrosis factor alpha (TNF-α) inhibitor; a recombinant human Ig G1 monoclonal antibody that binds to soluble and membrane-bound TNF-α, preventing its interaction with p55 and p75 TNF receptors, thereby reducing inflammation and immune activation.

Indications
OTEZLA

Treatment of adult patients with active psoriatic arthritis,Treatment of adult patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy,Treatment of adult patients with oral ulcers associated with Behçet's disease

HUMIRA

Rheumatoid arthritis (moderate to severe, active),Juvenile idiopathic arthritis (moderate to severe, active polyarticular),Psoriatic arthritis (active, moderate to severe),Ankylosing spondylitis (active),Crohn's disease (moderate to severe, active, in adults and pediatric patients 6 years and older),Ulcerative colitis (moderate to severe, active, in adults and pediatric patients 5 years and older),Plaque psoriasis (moderate to severe, chronic, in adults),Hidradenitis suppurativa (moderate to severe, in adults and adolescents 12 years and older),Uveitis (non-infectious, intermediate, posterior, or panuveitis, in adults and pediatric patients 2 years and older),Off-label: Behçet's disease, sarcoidosis, pyoderma gangrenosum, graft-versus-host disease

Pregnancy & Lactation

OTEZLA
HUMIRA
Teratogenic Risk
OTEZLA

Pregnancy Category C. No adequate and well-controlled studies in pregnant women. In animal studies, apremilast caused developmental toxicity at doses 2-3 times the MRHD (mouse) and equivalent to MRHD (monkey). First trimester: theoretical risk due to unknown effects on organogenesis; avoid unless benefit outweighs risk. Second and third trimesters: limited data; use only if clearly needed. Register patients in the Otezla Pregnancy Registry (1-877-311-8972).

HUMIRA

First trimester: Limited data, no clear increase in major malformations. Second and third trimesters: Known to cross placenta; increased risk of infection in infant. Avoid live vaccines for first 6 months.

Clinical Insights

OTEZLA
HUMIRA
Clinical Pearls
OTEZLA

Apremilast is contraindicated in pregnancy due to weight loss and potential fetal harm. Monitor for depression and suicidal ideation. Dose adjustment required in severe renal impairment (Cr Cl <30 m L/min). Titrate dose over first week to reduce GI side effects.

HUMIRA

HUMIRA (adalimumab) is a TNF-alpha inhibitor; screen for latent TB and hepatitis B prior to initiation. Do not administer live vaccines during therapy. Monitor for injection site reactions and serious infections. Consider checking for anti-drug antibodies if loss of response occurs.

Clinical Q&A

Frequently Asked Questions

1. What is the primary difference between OTEZLA and HUMIRA?

OTEZLA and HUMIRA are distinct pharmacological agents. OTEZLA belongs to the Phosphodiesterase-4 (PDE4) Inhibitor class and is primarily used for Treatment of adult patients with active psoriatic arthritisTreatment of adult patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapyTreatment of adult patients with oral ulcers associated with Behçet's disease. HUMIRA belongs to the TNF-alpha Inhibitor class and is primarily used for Rheumatoid arthritis (moderate to severe, active)Juvenile idiopathic arthritis (moderate to severe, active polyarticular)Psoriatic arthritis (active, moderate to severe)Ankylosing spondylitis (active)Crohn's disease (moderate to severe, active, in adults and pediatric patients 6 years and older)Ulcerative colitis (moderate to severe, active, in adults and pediatric patients 5 years and older)Plaque psoriasis (moderate to severe, chronic, in adults)Hidradenitis suppurativa (moderate to severe, in adults and adolescents 12 years and older)Uveitis (non-infectious, intermediate, posterior, or panuveitis, in adults and pediatric patients 2 years and older)Off-label: Behçet's disease, sarcoidosis, pyoderma gangrenosum, graft-versus-host disease. Their specific mechanisms of action, pharmacokinetic characteristics, and side effects differ.

2. Are OTEZLA and HUMIRA safe during pregnancy?

The maternal-fetal safety profiles of these drugs differ. OTEZLA carries a safety status of Category C, whereas HUMIRA safety is classified as Category C. Consult a board-certified physician or healthcare specialist to establish an accurate, individualized pregnancy risk assessment before starting either therapy.

Food Interactions
OTEZLA

No significant food interactions. May be taken with or without food. Avoid grapefruit and grapefruit juice as they may increase drug levels.

HUMIRA

No specific food interactions have been established for HUMIRA. However, patients should maintain a balanced diet and avoid grapefruit juice if taking concomitant medications that interact with grapefruit (e.g., some statins). Alcohol consumption should be moderated due to potential hepatotoxicity.

Lactation Summary
OTEZLA

No data on presence in human milk, effects on breastfed infant, or milk production. Animal studies show excretion in rat milk. M/P ratio not determined in humans. Because of potential for serious adverse reactions, advise patients not to breastfeed during treatment and for at least 1 week after last dose.

HUMIRA

Minimal transfer into breast milk; M/P ratio unknown. Not expected to cause harm, but caution advised due to potential immune suppression in infant.

Pregnancy Dosing
OTEZLA

No pharmacokinetic studies in pregnant women; dose adjustments not established. However, physiologic changes in pregnancy (increased plasma volume, renal clearance) may lower drug exposure; monitor therapeutic response and adjust dose if needed, though no specific guidelines exist.

HUMIRA

No dose adjustment required based on pregnancy pharmacokinetic changes; however, clinical response may vary, and dose adjustment should be guided by disease activity and risk-benefit assessment.
