MIRIKIZUMAB Drug Interactions: What You Need to Know

INTERACTIONS

7.1 CYP450 Substrates Increased concentrations of cytokines (e.g., IL-1, IL-6, IL-10, TNFα, IFN) during chronic inflammation associated with certain diseases including Crohn's disease may suppress the formation of CYP450 enzymes. Therapeutic proteins, including mirikizumab-mrkz, that decrease the concentrations of these pro-inflammatory cytokines may increase the formation of CYP450 enzymes resulting in decreased CYP450 substrate exposure. Upon initiation or discontinuation of OMVOH in patients treated with concomitant CYP450 substrates, monitor drug concentrations or other therapeutic parameters, and adjust the dosage of the CYP450 substrate as needed. See the prescribing information of specific CYP450 substrates.

OMVOH is contraindicated in patients with a history of serious hypersensitivity reaction to mirikizumab-mrkz or any of the excipients [see Warnings and Precautions ( 5.1 )] . History of serious hypersensitivity reaction to mirikizumab-mrkz or any of the excipients. ( 4 , 5.1 ).

AND PRECAUTIONS Hypersensitivity Reactions : Serious hypersensitivity reactions, including anaphylaxis and infusion-related reactions, have been reported. If a severe hypersensitivity reaction occurs, discontinue and initiate appropriate treatment. ( 5.1 ) Infections : OMVOH may increase the risk of infection. Do not initiate treatment with OMVOH in patients with a clinically important active infection until the infection resolves or is adequately treated. If a serious infection develops, do not administer OMVOH until the infection resolves. ( 5.2 ) Tuberculosis : Do not administer OMVOH to patients with active TB infection. Monitor patients receiving OMVOH for signs and symptoms of active TB during and after treatment. ( 5.3 ) Hepatotoxicity : Drug-induced liver injury has been reported. Monitor liver enzymes and bilirubin levels at baseline and for at least 24 weeks of treatment and thereafter according to routine patient management. Interrupt treatment if drug-induced liver injury is suspected, until this diagnosis is excluded. ( 5.4 ) Immunizations : Avoid use of live vaccines. ( 5.5 )

5.1 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis during intravenous infusion, have been reported with OMVOH administration. Infusion-related hypersensitivity reactions, including mucocutaneous erythema and pruritus, were reported during induction <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.1 )]</span> . If a severe hypersensitivity reaction occurs, discontinue OMVOH immediately and initiate appropriate treatment.

5.2 Infections OMVOH may increase the risk of infection <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.1 )]</span> . Do not initiate treatment with OMVOH in patients with a clinically important active infection until the infection resolves or is adequately treated. In patients with a chronic infection or a history of recurrent infection, consider the risks and benefits prior to prescribing OMVOH. Instruct patients to seek medical advice if signs or symptoms of clinically important acute or chronic infection occur. If a serious infection develops or an infection is not responding to standard therapy, monitor the patient closely and do not administer OMVOH until the infection resolves.

5.3 Tuberculosis Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with OMVOH. Do not administer OMVOH to patients with active TB infection. Initiate treatment of latent TB prior to administering OMVOH. Consider anti-TB therapy prior to initiation of OMVOH in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed. Monitor patients for signs and symptoms of active TB during and after OMVOH treatment. In clinical trials, subjects were excluded if they had evidence of active TB, a past history of active TB, or were diagnosed with latent TB at screening.

5.4 Hepatotoxicity A case of drug-induced liver injury (alanine aminotransferase [ALT] 18x the upper limit of normal (ULN), aspartate aminotransferase [AST] 10x ULN, and total bilirubin 2.4x ULN) in conjunction with pruritus was reported in a clinical trial subject following a longer than recommended induction regimen. OMVOH was discontinued. Liver test abnormalities eventually returned to baseline. Evaluate liver enzymes and bilirubin at baseline and for at least 24 weeks of treatment. Monitor thereafter according to routine patient management. Consider other treatment options in patients with evidence of liver cirrhosis. Prompt investigation of the cause of liver enzyme elevation is recommended to identify potential cases of drug-induced liver injury. Interrupt treatment if drug-induced liver injury is suspected, until this diagnosis is excluded. Instruct patients to seek immediate medical attention if they experience symptoms suggestive of hepatic dysfunction.

5.5 Immunizations Avoid use of live vaccines in patients treated with OMVOH. Medications that interact with the immune system may increase the risk of infection following administration of live vaccines. Prior to initiating therapy with OMVOH, complete all age-appropriate vaccinations according to current immunization guidelines. No data are available on the response to live or non-live vaccines in patients treated with OMVOH.
