Insights
Eli Lilly's Phase 3 VIVID-1 study results for mirikizumab indicate promising outcomes for patients with Crohn's disease, particularly those with previous biologic failures. The antibody's ability to achieve clinical remission and endoscopic response at one year is notable, especially given the challenging nature of treating these patients. Mirikizumab's performance compared to placebo demonstrates its potential as a robust treatment option. The findings suggest a significant advancement in the management of Crohn's disease, providing a new hope for patients who have not responded well to existing therapies. However, further studies and real-world data will be important to validate these results and understand long-term implications.
From a financial perspective, the successful Phase 3 results for mirikizumab could position Eli Lilly favorably in the market for inflammatory bowel disease treatments. The potential approval for Crohn's disease, in addition to its existing approval for ulcerative colitis, could expand Lilly's market share and revenue streams. The superiority to ustekinumab in certain endpoints is an important competitive advantage, though the lack of statistical significance in some comparisons should be noted. Investors should monitor regulatory submissions and upcoming studies closely, as these will be critical for the drug's commercial success. The safety profile being consistent with previous data is a positive signal, reducing the risk of unexpected liabilities.
The Crohn's disease treatment landscape is competitive, with numerous biologic agents available. Mirikizumab's ability to demonstrate significant clinical and endoscopic improvements positions it as a strong contender in this market. The differentiation in effectiveness for patients with prior biologic failure could attract a segment that is currently underserved by existing treatments. Eli Lilly's commitment to additional studies, including pediatric and long-term extension studies, indicates a strategic effort to establish mirikizumab as a comprehensive solution for various patient groups. Market penetration will depend on successful regulatory approvals and the drug's acceptance among healthcare providers and patients.
Nearly one-half of patients on mirikizumab achieved endoscopic response at 52 weeks; most of these patients were also in clinical remission
"Crohn's disease is a complex condition that, if untreated, may result in irreversible damage to the digestive tract. Mirikizumab patients achieved high rates of combined clinical remission and endoscopic response, two important treatment targets that are difficult to achieve in the same patient, at one year. This is particularly impressive for patients with previous biologic failure who are generally considered hard-to-treat," said Bruce Sands, M.D., M.S., Dr. Burrill B. Crohn Professor of Medicine and Chief of the Dr. Henry D. Janowitz Division of Gastroenterology, Icahn School of Medicine at Mount Sinai.* "Consistent results across patient populations underscore the potential impact of mirikizumab in individuals living with this condition."
Crohn's disease is a chronic, inflammatory bowel disease associated with progressive bowel damage, disability and decreased health-related quality of life. If not adequately controlled, it may lead to complications that require hospitalization and surgical intervention. A substantial proportion of patients do not experience adequate treatment outcomes, have secondary loss of response to maintenance therapy or do not tolerate existing therapies, including biologic agents. Patients with previous biologic failure may be more difficult to treat.
As previously reported, mirikizumab achieved both co-primary endpoints and all major secondary endpoints at Week 52 compared to placebo (p<0.000001), including:
- Proportion of participants achieving clinical response by patient reported outcomes (PRO)** at Week 12 and clinical remission (defined as a Crohn's Disease Activity Index [CDAI] Total Score <150) at Week 52 compared to placebo
- Proportion of participants achieving clinical response by PRO at Week 12 and endoscopic response (defined as ≥
50% reduction from baseline in Simple Endoscopic Score – Crohn's Disease [SES-CD] Total Score) at Week 52 compared to placebo
Consistent response rates and treatment effects were observed in patients with no prior biologic failure (bio-naïve) and harder-to-treat patients with previous biologic failure:
39.3% of bio-naïve and36.7% of bio-failed patients taking mirikizumab achieved composite Week 12 PRO clinical response and Week 52 endoscopic response compared to11.8% and6.2% of placebo, respectively47.3% of bio-naïve and43.4% of bio-failed patients taking mirikizumab achieved composite Week 12 PRO clinical response and Week 52 clinical remission by CDAI, compared to26.5% and12.4% of placebo, respectively
At one year, clinical remission and endoscopic response were achieved by
Patients taking mirikizumab achieved combined Week 52 clinical remission and endoscopic response at nominally statistically significant higher rates compared to patients on ustekinumab (
Additionally, in the population with previous biologic failure, numerically greater rates were observed with mirikizumab compared to ustekinumab for endoscopic response, endoscopic remission (SES-CD total score ≤4, a ≥2-point reduction from baseline and no subscore >1 in any individual variable), and corticosteroid-free CDAI clinical remission at Week 52. These observed differences were not statistically significant.
The overall safety profile of mirikizumab in patients with moderately to severely active Crohn's disease was consistent with the known safety profile in patients with ulcerative colitis. The frequency of serious adverse events was greater in placebo than mirikizumab. The most common adverse events were COVID-19, anemia, arthralgia, headache, upper respiratory tract infection, nasopharyngitis and injection site reaction.
"After one year of treatment, more than one-half of patients treated with mirikizumab achieved clinical remission and nearly one-half achieved endoscopic response. Remarkably, the majority of patients who achieved either of these endpoints, achieved both together," said Mark Genovese, M.D., senior vice president of Lilly Immunology development. "Lilly is committed to developing innovative treatments, like mirikizumab, that may improve upon the standard of care for people impacted by inflammatory bowel disease and immune-mediated diseases."

Lilly is committed to finding solutions to elevate care and improve treatment outcomes for people living with inflammatory bowel diseases. Lilly has ongoing studies to evaluate the efficacy and safety of mirikizumab in other populations with Crohn's disease, including a Phase 3 study in pediatric patients (NCT05509777) and a long-term extension study of patients with moderately to severely active Crohn's disease (NCT04232553). Omvoh™ (mirikizumab-mrkz) is approved for the treatment of moderately to severely active ulcerative colitis (UC) in adults and has additional ongoing trials in UC, including a study in pediatric patients (NCT05784246) and a study to evaluate the long-term efficacy and safety of mirikizumab in adults (NCT03519945). Lilly is continuing to lead the science with an open-label UC trial studying two new endpoints in the assessment of bowel urgency with frequency and deferral time, both of which impact the quality of life for patients (NCT05767021).

Indications and Usage for Omvoh™ (mirikizumab-mrkz) (in
Omvoh™ is indicated for the treatment of moderately to severely active ulcerative colitis in adults.
Important Safety Information for Omvoh (mirikizumab-mrkz)
CONTRAINDICATIONS - Omvoh is contraindicated in patients with a history of serious hypersensitivity reaction to mirikizumab-mrkz or any of the excipients.
WARNINGS AND PRECAUTIONS
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. If a severe hypersensitivity reaction occurs, discontinue Omvoh immediately and initiate appropriate treatment.
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. 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.
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 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 history of active TB, or were diagnosed with latent TB at screening.
Hepatotoxicity
Drug-induced liver injury in conjunction with pruritus was reported in a clinical trial patient 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.
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, 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.

About Omvoh™
Omvoh (mirikizumab-mrkz) is an interleukin-23p19 antagonist indicated for the treatment of moderately to severely active ulcerative colitis in adults. Omvoh selectively targets the p19 subunit of IL-23 and inhibits the IL-23 pathway. Inflammation due to over-activation of the IL-23 pathway plays a critical role in the pathogenesis of ulcerative colitis. Treatment of ulcerative colitis with Omvoh starts with 300-mg IV infusions, once every four weeks for a total of three infusions, and transitions to two, 100-mg subcutaneous injections every four weeks during maintenance treatment.
