Bristol Myers Squibb Announces Positive Topline Results from Pivotal Phase 3 True North Trial Evaluating Zeposia (ozanimod) in Patients with Moderate to Severe Ulcerative Colitis
Study met primary endpoints of clinical remission in induction at Week 10 and in maintenance at Week 52
Zeposia is the first oral sphingosine-1-phosphate (S1P) receptor modulator to demonstrate benefit in moderate to severe ulcerative colitis in a Phase 3 study
The safety profile of Zeposia in the True North trial was consistent with that observed in previously reported trials. The company will complete a full evaluation of the True North data and work with investigators to present detailed results at a future medical meeting, as well as discuss these results with health authorities.
“Patients with ulcerative colitis can struggle to effectively manage this often unpredictable and potentially debilitating disease. The True North results are encouraging for patients living with moderate to severe ulcerative colitis as Zeposia demonstrated consistency across key clinical and endoscopic endpoints, suggesting Zeposiamay address the need for new oral therapy options with a favorable benefit to risk profile in the treatment journey,” said
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, cohort 1 patients were randomized 2:1 to Zeposia or placebo and treated once daily for 10 weeks. Cohort 2 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, 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.
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 are the proportion of patients in clinical remission based on a composite clinical and endoscopic score (3-component
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). 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 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 egress 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.
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: ZEPOSIAmay 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 ZEPOSIAin patients with an active infection until the infection is resolved. Consider interruption of treatment with ZEPOSIAif 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, ZEPOSIAshould 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 ZEPOSIAand perform an appropriate diagnostic evaluation. If confirmed, treatment with ZEPOSIAshould be discontinued
- In clinical studies, patients who received ZEPOSIAwere not to receive concomitant treatment with antineoplastic, non-corticosteroid immunosuppressive, or immune-modulating therapies used for treatment of MS. Concomitant use of ZEPOSIAwith any of these therapies would be expected to increase the risk of immunosuppression. When switching to ZEPOSIAfrom 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 ZEPOSIAmay result in a transient decrease in heart rate and atrioventricular conduction delays, dose titration is recommended to help reduce cardiac effects. Initiation of ZEPOSIAwithout dose escalation may result in greater decreases in heart rate. If treatment with ZEPOSIAis 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 ZEPOSIAshould be discontinued if significant liver injury is confirmed. Caution should be exercised when using ZEPOSIAin 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: ZEPOSIAmay 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 ZEPOSIAin patients with macular edema has not been evaluated; potential benefits and risks for the individual patient should be considered if deciding whether ZEPOSIAshould 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 ZEPOSIAshould 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 ZEPOSIAtreatment 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.
