Warnings/Precautions

Concerns related to adverse effects:

• Antibody formation: Formation of neutralizing anti-drug antibodies may occur but has not been associated with loss of efficacy for guselkumab (AAD/NPF [Menter 2019]).

• Hepatotoxicity: Drug-induced liver injury (AST 11 × ULN, ALT 18 × ULN, and total bilirubin 2.4 × ULN) occurred in a Crohn disease clinical trial patient receiving 3 doses of a higher than recommended induction dose; LFTs returned to normal following discontinuation of therapy, corticosteroid administration, and hospitalization. Consider other treatment options in patients with acute liver disease or cirrhosis.

• Hypersensitivity reactions: Serious hypersensitivity reactions, including anaphylaxis, may occur; may require hospitalization. Discontinue use and initiate appropriate therapy if serious hypersensitivity reactions occur.

• Infections: Guselkumab may increase the risk of infections; upper respiratory tract infections, gastroenteritis, tinea infections, and herpes simplex infections have occurred more frequently. Consider the risks versus benefits prior to treatment initiation in patients with a history of chronic or recurrent infection; treatment should not be initiated in patients with clinically important active infections until it is resolved or treated. Monitor for infections; patients should seek medical attention for signs/symptoms of a clinically important infection (acute or chronic). If a serious infection develops or is unresponsive to appropriate therapy for the infection, monitor closely and discontinue guselkumab until the infection resolves.

• Tuberculosis: Patients should be evaluated for tuberculosis (TB) infection (latent TB) prior to initiating therapy. Do not administer to patients with TB disease (active TB). Treatment for TB infection should be administered prior to administering guselkumab. Consider anti-TB therapy prior to treatment initiation in patients with a history of TB infection or disease in whom an adequate course of TB treatment cannot be confirmed. Monitor closely for signs/symptoms of TB disease during and after guselkumab treatment.

Special populations:

• Patients with rheumatic musculoskeletal disease undergoing hip or knee replacement surgery: Hold biologic disease-modifying antirheumatic drugs (DMARDs) prior to surgery and plan surgery after the next dose is due. Surgery can occur after holding medication for 1 full dosing cycle (eg, for medications administered every 4 weeks, schedule surgery 5 weeks from last administered dose); therapy can be restarted once surgical wound shows evidence of healing (eg, no swelling, erythema, or drainage), sutures/staples are removed, and no ongoing nonsurgical site infections (typically ~14 days to reduce infection risk). Decisions to withhold therapy should be based on shared decision making; ensure the patient and their provider weigh risks of interrupting therapy and disease control versus risks of continuing therapy and surgical complications (ACR/AAHKS [Goodman 2022]).

Other warnings/precautions:

• Immunizations: Patients should be brought up to date with all immunizations before initiating therapy. Live vaccines should not be given concurrently; there are no data available concerning secondary transmission of infection by live vaccines in patients receiving therapy.

Reproductive Considerations

In general, patients who may become pregnant should use effective contraception while using biologic therapy for the treatment of psoriasis (Smith 2020; Yeung 2020). Treatment algorithms are available for use of biologics in patients with inflammatory bowel disease planning to become pregnant (Mahadevan 2019).

Pregnancy Considerations

Guselkumab is a humanized monoclonal antibody (IgG1). Human IgG crosses the placenta. Fetal exposure is dependent upon the IgG subclass, maternal serum concentrations, placental integrity, newborn birth weight, and GA, generally increasing as pregnancy progresses. The lowest exposure would be expected during the period of organogenesis and the highest during the third trimester (Clements 2020; Palmeira 2012; Pentsuk 2009).

Outcome data following maternal use of guselkumab during pregnancy are limited (Al-Khawaga 2021; Dernoncourt 2023). Agents other than guselkumab are currently recommended for the treatment of psoriasis in pregnancy (AAD/NPF [Menter 2019]; Yeung 2020). Treatment algorithms are available for use of biologics in pregnant patients with inflammatory bowel disease (Mahadevan 2019).

Data collection to monitor pregnancy and infant outcomes following exposure to guselkumab is ongoing. Patients exposed to guselkumab during pregnancy are encouraged to enroll themselves in the pregnancy registry by visiting www.mothertobaby.org/ongoing-study/tremfya-guselkumab, calling 1-877-311-8972, or emailing [email protected].

Breastfeeding Considerations

It is not known if guselkumab is present in breast milk.

Guselkumab is a humanized monoclonal antibody (IgG1). Human IgG is present in breast milk; concentrations are dependent upon IgG subclass and postpartum age (Anderson 2021). According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother.

Monitoring Parameters

Prior to therapy start:

• Evaluate for malignancy (especially skin cancer), current or latent infection, lymphadenopathy, ensure age-appropriate vaccinations are up to date, and, in general, no live vaccines are administered within 4 weeks of starting therapy (AAD/NPF [Menter 2019]; EuroGuiDerm [Nast 2024]). Refer to institutional protocols for vaccination and monitoring requirements prior to initiating therapy.

• Labs: CBC with differential; complete metabolic panel; bilirubin and LFTs in Crohn disease or ulcerative colitis patients; testing for tuberculosis (TB) infection (latent TB) (eg, Quantiferon Gold) or interferon gamma release assay for TB in patients who have had Bacillus Calmette-Guerin (BCG) vaccine; chest radiograph if testing for TB infection is positive; serologic testing for hepatitis B virus (HBV) (HBsAg, HBsAb, HBAbcore), hepatitis C virus antibody, HIV, pregnancy test, C-reactive protein (AAD/NPF [Menter 2019]; EuroGuiDerm [Nast 2024]).

During therapy:

• Evaluate for infection, malignancy (specifically skin cancer screening, especially for patients who have a history of skin cancer or UV phototherapy), infusion/injection site reactions, and symptoms consistent with posterior reversible encephalopathy syndrome or axial polyneuropathy (AAD/NPF [Menter 2019]; EuroGuiDerm [Nast 2024]).

• Labs: CBC and LFTs every 3 to 6 months; bilirubin and LFTs for at least 16 weeks of treatment and then periodically in Crohn disease or ulcerative colitis patients; pregnancy test as needed; yearly testing/chest radiograph for TB in high-risk patients (eg, contact with individuals with TB disease [active TB]) (AAD/NPF [Menter 2019]; EuroGuiDerm [Nast 2024]); hepatitis B carriers should be periodically evaluated for signs/symptoms of active hepatitis B infection (AAD/NPF [Menter 2019]).

After therapy:

• Periodically evaluate patients who are hepatitis B carriers for signs/symptoms of active hepatitis B infection (AAD/NPF [Menter 2019]).

Mechanism of Action

Human IgG1 monoclonal antibody selectively binds with IL-23, thereby reducing serum levels of IL-17A, IL-17F, and IL-22. Guselkumab inhibits the release of proinflammatory cytokines and chemokines.

Pharmacokinetics (Adult Data Unless Noted)

Onset of action: Psoriasis: Response best determined after 12 weeks (AAD/NPF [Menter 2019]).

Distribution: Vd: Crohn disease: 11.4 L; plaque psoriasis: 13.5 L; ulcerative colitis: 10.1 L.

Metabolism: Degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG.

Bioavailability: SUBQ: ~49%.

Half-life elimination: Crohn disease and ulcerative colitis: 17 days; plaque psoriasis: 15 to 18 days.

Time to peak: SUBQ: 5.5 days.
