Overview

Mirikizumab-mrkz, a humanized immunoglobulin G4 (IgG4) monoclonal antibody, is an interleukin-23 antagonist.

Mirikizumab-mrkz is a humanized immunoglobulin G4 (IgG4) variant monoclonal antibody that selectively binds to the p19 subunit of interleukin 23 cytokine and inhibits its interaction with the interleukin 23 receptor; it does not bind interleukin 12. Interleukin 23 is involved in mucosal inflammation and affects the differentiation, expansion, and survival of T cell subsets, and innate immune cell subsets, which represent sources of pro-inflammatory cytokines. Mirikizumab-mrkz inhibits the release of pro-inflammatory cytokines and chemokines.

Research in animal models has shown that pharmacologic inhibition of interleukin 23 p19 can ameliorate intestinal inflammation. Mirikizumab-mrkz is produced in Chinese hamster ovary cells by recombinant DNA technology and is composed of two identical light chain polypeptides and two identical heavy chain polypeptides.

Mirikizumab-mrkz exhibits linear pharmacokinetics with dose-proportional increase in exposure over a dose range of 60 to 2400 mg given as an IV injection and over a dose range of 200 to 400 mg given as a subcutaneous injection. There is no apparent accumulation of mirikizumab-mrkz in the serum over time when administered as a subcutaneous injection every 4 weeks. Following subcutaneous dosing of mirikizumab-mrkz, the median time to maximum serum concentration is 5 days post dose with a geometric mean bioavailability of 44% (ulcerative colitis) and 36.3% (Crohn's disease).

Injection site location (abdomen, upper arm, or thigh) does not significantly influence bioavailability following subcutaneous injection. Following IV administration of 300 mg (the recommended induction dose for ulcerative colitis) in patients weighing >=90 kg, the estimated geometric mean average concentration (Cavg) was 20% lower compared with patients weighing <90 kg. Following subcutaneous administration of 200 mg (recommended maintenance dose for ulcerative colitis) in patients weighing >=90 kg, the estimated geometric mean Cavg was 38% lower compared with patients weighing <90 kg.

The rate of clinical remission and clinical response in ulcerative colitis did not differ significantly between patients weighing >=90 kg and patients weighing <90 kg. Following IV administration of 900 mg (the recommended induction dose for Crohn's disease) in patients weighing >=90 kg, the estimated geometric mean average concentration (Cavg) was 13% lower compared with patients weighing <90 kg. Following subcutaneous administration of 300 mg (recommended maintenance dose for Crohn's disease) in patients weighing >=90 kg, the estimated geometric mean Cavg was 34% lower compared with patients weighing <90 kg.

The rate of clinical remission and clinical response in Crohn's disease did not differ significantly between patients weighing >=90 kg and patients weighing <90 kg. Mirikizumab-mrkz is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG. The elimination half-life is 9.3 days.

There are no clinically significant differences in the pharmacokinetics of mirikizumab-mrkz based on age (range: 18 to 79 years), sex, race, or mild and moderate renal impairment (estimated creatinine clearance by Cockcroft-Gault equation 30--89 mL/minute).

USES: This medication is used to treat certain bowel diseases (ulcerative colitis, Crohn's disease). Mirikizumab belongs to a class of drugs known as monoclonal antibodies. It works by blocking a certain natural protein in your body (interleukin-23) that may cause inflammation and swelling.

Indications

The following indications are listed for Omvoh:

  • Crohn's Disease
  • Ulcerative Colitis

Also known as: Colitis Ulcerativa, Regional Enteritis, Regional Ileocolitis.

Dosing

No dosing information is available for this tab.

Drug interactions

There have been no drug-drug interaction studies conducted in patients with ulcerative colitis at the recommended dosage.

Because mirikizumab-mrkz is a monoclonal antibody expected to be metabolized by proteolytic degradation to peptides and amino acids, it is not likely to have any direct effect on drug-metabolizing enzymes.

Contraindications

*History of serious hypersensitivity reaction to mirikizumab-mrkz or any of the excipients.

Adverse reactions

Induction in ulcerative colitis: The most common adverse effects of mirikizumab-mrkz (>=2% of patients) reported in clinical studies include upper respiratory tract infections and arthralgia.

Maintenance in ulcerative colitis: The most common adverse effects of mirikizumab-mrkz (>=2% of patients) reported in clinical studies include upper respiratory tract infections, injection site reactions, arthralgia, rash, headache, and herpes viral infection.

The most common adverse effects of mirikizumab-mrkz (>=5% of patients) reported in clinical studies of Crohn's disease include upper respiratory tract infections, injection site reactions, headache, arthralgia, and elevated liver tests.

Precautions
