Sylvant (siltuximab) Disease Interactions

There are 5 disease interactions with Sylvant (siltuximab):

Major

Interleukin Inhibitors (Includes Sylvant) ↔ Infections

Severe Potential Hazard, Moderate plausibility

Applies to: Infection - Bacterial/Fungal/Protozoal/Viral

There have been reports of serious infections, including infections with opportunistic pathogens, and reactivation of latent infections in patients receiving interleukin inhibitors. Treatment with these agents should not be initiated in patients with an active infection until the infection resolves or is adequately treated. Caution is recommended when considering the use of interleukin inhibitors in patients with a history of recurrent infections, underlying conditions which may predispose them to infections, or chronic, latent, or localized infections.

Moderate

Interleukin Inhibitors (Includes Sylvant) ↔ Immunization

Moderate Potential Hazard, Moderate plausibility

Applies to: Vaccination

Patients requiring non-live vaccination during a course of therapy with interleukin inhibitors may not be protected from the vaccine as the immune response might not be sufficient to prevent the disease. It is recommended to be up-to-date with all required immunizations, as recommended by current immunization guidelines, before initiating therapy with these agents. Patients treated with interleukin inhibitors should not receive live vaccines. Caution is advised when administering live vaccines to household contacts of patients receiving interleukin inhibitors because of the potential risk for shedding from the household contact and transmission to patient.

Moderate

Siltuximab (Includes Sylvant) ↔ Gastrointestinal Perforation

Moderate Potential Hazard, Moderate plausibility

Applies to: Gastrointestinal Perforation

The use of siltuximab may cause gastrointestinal (GI) perforation. Use with caution in patients who may be at increased risk for GI perforation. It is recommended to closely monitor patients for symptoms indicative or that may be associated with GI perforation.

Moderate

Siltuximab (Includes Sylvant) ↔ Hepatic Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

Based on a population pharmacokinetic analysis using data from clinical trials in patients, no significant difference in siltuximab clearance was observed in patients with preexisting mild to moderate hepatic impairment (Child-Pugh Class A and B, respectively) compared to patients with baseline normal hepatic function. No initial dosage adjustment is necessary for patients with mild to moderate hepatic impairment. Care should be taken when using this agent in patients with baseline severe hepatic impairment (Child-Pugh Class C) as the potential effect on siltuximab pharmacokinetics cannot be determined as clinical and pharmacokinetic data are not available.

Moderate

Siltuximab (Includes Sylvant) ↔ Renal Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

Based on a population pharmacokinetic analysis using data from clinical trials in patients, no significant difference in siltuximab clearance was observed in patients with preexisting renal impairment (creatinine clearance (CrCl) >=15 mL/min) compared to patients with baseline normal renal function (CrCl)>= 90 mL/min). No initial dosage adjustment is necessary for patients with CrCl >= 15 mL/min. Care should be taken when using this agent in patients with end-stage renal disease as the potential effect on siltuximab pharmacokinetics cannot be determined. Clinical monitoring of renal function is recommended.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
