Bristol Myers Squibb Presents Positive Late-Breaking Data from Phase 3 True North Trial Evaluating Zeposia (ozanimod) in Adult Patients with Moderate to Severe Ulcerative Colitis
Bristol Myers Squibb (NYSE:BMY) today announced detailed results from True North, a pivotal, placebo-controlled Phase 3 trial evaluating oral Zeposia (ozanimod) as an induction and maintenance therapy in adult patients with moderate to severe ulcerative colitis (UC). True North met both primary endpoints, demonstrating highly statistically significant and clinically meaningful results for clinical remission compared to placebo at induction at Week 10 (18.4% versus 6.0%; p-value<0.0001) and in maintenance at Week 52 (37.0% vs 18.5%; p<0.0001). The study also met key secondary endpoints, including clinical response, endoscopic improvement and mucosal healing in induction at Week 10 and in maintenance at Week 52. Significantly more patients treated with Zeposia compared to placebo achieved clinical response at Week 10 (47.8% vs 25.9%; p<0.0001) and at Week 52 (60.0% vs 41.0%; p<0.0001) with consistent results across sub-analyses. The overall safety observed was consistent with the known safety profile for Zeposia and patients with moderate to severe UC.
Efficacy and safety results from the 10-week induction period (Abstract LB02, UEG Research Prize 2020 Session) and from the maintenance period at Week 52 (Abstract LB10) from True North will be presented on October 11 at 12:32 CEST and at 15:24 CEST, respectively, in two late-breaking oral presentations at UEG Week Virtual 2020.
“The data from the Zeposia True North trial demonstrate patients with moderate to severe ulcerative colitis achieved clinically meaningful improvements in key clinical, endoscopic and mucosal healing endpoints,” said William Sandborn, M.D., chief, Division of Gastroenterology and director, Inflammatory Bowel Disease Center at University of California (UC), San Diego Health and professor of medicine, UC San Diego School of Medicine. “Notably, the endoscopic and histologic benefits, which can be difficult to achieve, suggest Zeposia has the potential to address the need for a safe and effective oral treatment option for this serious, chronic disease.”
All key secondary efficacy endpoints showed statistically significant improvements for patients treated with Zeposia compared to placebo at Week 10 and Week 52. Findings include:
Induction Period (Week 10)
- At Week 10, key secondary endpoints were highly statistically significant and showed more patients treated with Zeposia achieved clinical response, endoscopic improvement and mucosal healing compared to placebo.
- In patients with prior TNF-inhibitor exposure, clinical remission results favored Zeposia over placebo, but findings were not significant at Week 10. A nominally statistically significant difference was observed for clinical response (p=0.008).
Maintenance Period (Week 52)
- At Week 52, highly statistically significant results were achieved for patients treated with Zeposia compared to placebo, including clinical response, endoscopic improvement, maintenance of remission, corticosteroid-free remission, mucosal healing and durable remission.
- Clinical remission and response improved with Zeposia regardless of previous TNF-inhibitor use at Week 52.
In the induction period, the most common treatment-emergent adverse events (TEAEs) for patients who received Zeposia versus placebo, respectively, were anemia (4.2% vs 5.6%), nasopharyngitis (3.5% vs 1.4%) and headache (3.3% vs 1.9%). In the maintenance period, the most common TEAEs for Zeposia versus placebo, respectively, were alanine aminotransferase increase (4.8% vs 0.4%; no serious events), and headache (3.5% vs 0.4%).
“These Zeposia True North results represent a meaningful achievement for patients living with ulcerative colitis, many of whom have an inadequate response or do not respond at all to currently available therapies,” said Mary Beth Harler, M.D., head of Immunology and Fibrosis Development, Bristol Myers Squibb. “We look forward to working with health authorities to bring Zeposia to this patient population and remain committed to pursuing new scientific advances to help deliver transformational medicines for the gastroenterology community.”

About True North
True North is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial comparing the efficacy and safety of Zeposia 1mg in patients with moderate to severe ulcerative colitis who did not adequately respond to prior treatment. In the induction phase, a total of 645 patients were randomized to receive Zeposia (n=429) or placebo (n=216), of whom 94% and 89%, respectively, completed the induction period. At study entry, mean age was 42 years, 60% were male and mean disease duration was 7 years; patient characteristics were well-balanced across treatment groups. Cohort 1 patients were randomized 2:1 to Zeposia or placebo and treated once daily for 10 weeks. Cohort 2 (n=367) was an open-label arm, and included to allow adequate patient numbers for the maintenance phase of the trial. Cohort 2 patients were treated once daily with Zeposia for 10 weeks.
For the maintenance phase, 457 patients were re-randomized to maintenance treatment with either Zeposia (n=230) or placebo (n=227). Of these, 80% and 54.6% of patients who received Zeposia and placebo, respectively, completed the study; disease relapse (13.5% Zeposia, 33.9% placebo) was the most common reason for discontinuation. Patients on Zeposia from either Cohort 1 or 2 who achieved clinical response in the induction phase at Week 10 were re-randomized 1:1 to Zeposia or placebo through Week 52. Patients on placebo who achieved clinical response in the induction phase at Week 10 remained on placebo during this blinded maintenance phase.
In Cohort 1 of the induction phase and in the re-randomized patient group in the maintenance phase, 30% of patients had prior TNF-inhibitor exposure.
All eligible patients were rolled into an open-label extension trial, which is ongoing and designed to assess the longer-term profile of Zeposia for the treatment of moderate to severe ulcerative colitis.
The primary endpoints in True North are the proportion of patients in clinical remission based on a composite clinical and endoscopic score (3-component Mayo Score) at Week 10 in the induction phase, and at Week 52 for the maintenance phase. Secondary endpoints include the proportion of patients achieving clinical response at Week 10 and Week 52, the proportion of patients with endoscopic improvement (endoscopy score ≤1) at Week 10 and Week 52, the proportion of patients with mucosal healing at Week 10 and Week 52, and clinical remission at Week 52 in patients that were in remission at Week 10. In this study, mucosal healing is defined as endoscopic improvement with histologic remission. More information can be found on www.clinicaltrials.gov, NCT02435992.
Topline results from True North were previously announced in June 2020.
About Ulcerative Colitis
Ulcerative colitis, a chronic inflammatory bowel disease (IBD), is characterized by an abnormal, prolonged immune response that creates long-lasting inflammation and ulcers (sores) in the mucosa (lining) of the large intestine (colon) or rectum. Symptoms, including bloody stools, severe diarrhea and frequent abdominal pain, usually develop over time rather than suddenly. Ulcerative colitis has a major impact on patients' health-related quality of life, including physical functioning, social and emotional well-being and ability to work. Many patients have an inadequate response or do not respond at all to currently available therapies. It is estimated that approximately 12.6 million people worldwide have IBD.
About Zeposia (ozanimod)
Zeposia (ozanimod) is an oral, sphingosine-1-phosphate (S1P) receptor modulator that binds with high affinity to S1P receptors 1 and 5. Zeposia reduces the capacity of lymphocytes to exit from lymph nodes, reducing the number of circulating lymphocytes in peripheral blood. The mechanism by which Zeposia exerts therapeutic effects in ulcerative colitis is unknown but may involve the reduction of lymphocyte migration into the inflamed intestinal mucosa.
The U.S. Food and Drug Administration (FDA) approved Zeposia for the treatment of adults with relapsing forms of multiple sclerosis (RMS) in March 2020. The European Commission approved Zeposia for the treatment of adult patients with relapsing remitting multiple sclerosis (RRMS) with active disease as defined by clinical or imaging features in May 2020. Bristol Myers Squibb is also investigating Zeposia for the treatment of moderately to severely active Crohn’s disease in the ongoing Phase 3 YELLOWSTONE clinical trial program.
U.S. FDA-APPROVED INDICATION FOR ZEPOSIA
ZEPOSIA is indicated for the treatment of relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.
IMPORTANT SAFETY INFORMATION
- Patients who in the last 6 months, experienced myocardial infarction, unstable angina, stroke, transient ischemic attack (TIA), decompensated heart failure requiring hospitalization, or Class III/IV heart failure or have a presence of Mobitz type II second or third-degree atrioventricular (AV) block, sick sinus syndrome, or sino-atrial, unless the patient has a functioning pacemaker
- Patients with severe untreated sleep apnea
- Patients taking a monoamine oxidase (MAO) inhibitor
Infections: ZEPOSIA may increase the susceptibility to infections. Life-threatening and rare fatal infections have occurred in patients receiving ZEPOSIA. Obtain a recent (i.e., within 6 months or after discontinuation of prior MS therapy) complete blood count (CBC) including lymphocyte count before initiation of ZEPOSIA. Delay initiation of ZEPOSIA in patients with an active infection until the infection is resolved. Consider interruption of treatment with ZEPOSIA if a patient develops a serious infection. Continue monitoring for infections up to 3 months after discontinuing ZEPOSIA
- Herpes zoster was reported as an adverse reaction in ZEPOSIA -treated patients. Herpes simplex encephalitis and varicella zoster meningitis have been reported with sphingosine 1-phosphate (S1P) receptor modulators. Patients without a healthcare professional-confirmed history of varicella (chickenpox), or without documentation of a full course of vaccination against varicella zoster virus (VZV), should be tested for antibodies to VZV before initiating ZEPOSIA. A full course of vaccination for antibody-negative patients with varicella vaccine is recommended prior to commencing treatment with ZEPOSIA
- Cases of fatal cryptococcal meningitis (CM) were reported in patients treated with another S1P receptor modulator. If CM is suspected, ZEPOSIA should be suspended until cryptococcal infection has been excluded. If CM is diagnosed, appropriate treatment should be initiated.
- Progressive Multifocal Leukoencephalopathy (PML) is an opportunistic viral infection of the brain that typically occurs in patients who are immunocompromised, and that usually leads to death or severe disability. No cases of PML were identified in active-controlled MS clinical trials with ZEPOSIA. PML has been reported in patients treated with S1P receptor modulators and other MS therapies and has been associated with some risk factors. If PML is suspected, withhold ZEPOSIA and perform an appropriate diagnostic evaluation. If confirmed, treatment with ZEPOSIA should be discontinued
- In clinical studies, patients who received ZEPOSIA were not to receive concomitant treatment with antineoplastic, non-corticosteroid immunosuppressive, or immune-modulating therapies used for treatment of MS. Concomitant use of ZEPOSIA with any of these therapies would be expected to increase the risk of immunosuppression. When switching to ZEPOSIA from immunosuppressive medications, consider the duration of their effects and their mode of action to avoid unintended additive immunosuppressive effects
- Use of live attenuated vaccines should be avoided during and for 3 months after treatment with ZEPOSIA. If live attenuated vaccine immunizations are required, administer at least 1 month prior to initiation of ZEPOSIA
Bradyarrhythmia and Atrioventricular Conduction Delays: Since initiation of ZEPOSIA may result in a transient decrease in heart rate and atrioventricular conduction delays, dose titration is recommended to help reduce cardiac effects. Initiation of ZEPOSIA without dose escalation may result in greater decreases in heart rate. If treatment with ZEPOSIA is considered, advice from a cardiologist should be sought for those individuals:
- with significant QT prolongation
- with arrhythmias requiring treatment with Class 1a or III anti-arrhythmic drugs
- with ischemic heart disease, heart failure, history of cardiac arrest or myocardial infarction, cerebrovascular disease, and uncontrolled hypertension
- with a history of Mobitz type II second-degree or higher AV block, sick-sinus syndrome, or sinoatrial heart block
Liver Injury: Elevations of aminotransferases may occur in patients receiving ZEPOSIA. Obtain liver function tests, if not recently available (i.e., within 6 months), before initiation of ZEPOSIA. Patients who develop symptoms suggestive of hepatic dysfunction should have hepatic enzymes checked and ZEPOSIA should be discontinued if significant liver injury is confirmed. Caution should be exercised when using ZEPOSIA in patients with history of significant liver disease
Fetal Risk: There are no adequate and well-controlled studies in pregnant women. Based on animal studies, ZEPOSIA may cause fetal harm. Women of childbearing potential should use effective contraception to avoid pregnancy during treatment and for 3 months after stopping ZEPOSIA
Increased Blood Pressure: Increase in systolic pressure was observed after about 3 months of treatment and persisted throughout treatment. Blood pressure should be monitored during treatment and managed appropriately. Certain foods that may contain very high amounts of tyramine could cause severe hypertension in patients taking ZEPOSIA. Patients should be advised to avoid foods containing a very large amount of tyramine while taking ZEPOSIA
Respiratory Effects: ZEPOSIA may cause a decline in pulmonary function. Spirometric evaluation of respiratory function should be performed during therapy, if clinically indicated
Macular edema: S1P modulators have been associated with an increased risk of macular edema. Patients with a history of uveitis or diabetes mellitus are at increased risk. Patients with a history of these conditions should have an ophthalmic evaluation of the fundus, including the macula, prior to treatment initiation and regular follow-up examinations. An ophthalmic evaluation is recommended in all patients at any time if there is a change in vision. Continued use of ZEPOSIA in patients with macular edema has not been evaluated; potential benefits and risks for the individual patient should be considered if deciding whether ZEPOSIA should be discontinued
Posterior Reversible Encephalopathy Syndrome (PRES): Rare cases of PRES have been reported in patients receiving a S1P receptor modulator. If a ZEPOSIA-treated patient develops unexpected neurological or psychiatric symptoms or any symptom/sign suggestive of an increase in intracranial pressure, a complete physical and neurological examination should be conducted. Symptoms of PRES are usually reversible but may evolve into ischemic stroke or cerebral hemorrhage. Delay in diagnosis and treatment may lead to permanent neurological sequelae. If PRES is suspected, treatment with ZEPOSIA should be discontinued
Unintended Additive Immunosuppressive Effects from Prior Immunosuppressive or Immune-Modulating Drugs: When switching from drugs with prolonged immune effects, the half-life and mode of action of these drugs must be considered to avoid unintended additive immunosuppressive effects while at the same time minimizing risk of disease reactivation. Initiating treatment with ZEPOSIA after treatment with alemtuzumab is not recommended
Severe Increase in Disability After Stopping ZEPOSIA: Severe exacerbation of disease, including disease rebound, has been rarely reported after discontinuation of a S1P receptor modulator. The possibility of severe exacerbation of disease should be considered after stopping ZEPOSIA treatment so patients should be monitored upon discontinuation
Immune System Effects After Stopping ZEPOSIA: After discontinuing ZEPOSIA, the median time for lymphocyte counts to return to the normal range was 30 days with approximately 90% of patients in the normal range within 3 months. Use of immunosuppressants within this period may lead to an additive effect on the immune system, therefore caution should be applied when initiating other drugs 4 weeks after the last dose of ZEPOSIA
Most common Adverse Reactions (≥ 4%): upper respiratory infection, hepatic transaminase elevation, orthostatic hypotension, urinary tract infection, back pain, and hypertension.
