Clinical response
Select inclusion criteria included1,2:
  • Adults with moderately to severely active UC (an mMS‡ of 5 to 9) who had an inadequate response, a loss of response, or an intolerance to ≥1 treatment options: oral aminosalicylates, corticosteroids, thiopurines, JAKi, or biologics (eg, TNF blockers, anti-integrins, anti-IL 12/23)
  • Disease severity was assessed in patients with a modified Mayo score (mMS)‡ of 5 to 9 at baseline
  • Concomitant use of select UC therapies§ was permitted, including stable daily doses of oral 5-ASAs and/or oral corticosteroids (prednisone [≤20 mg/day], budesonide [≤9 mg/day], or equivalent steroid), provided they were on a stable dose 2 weeks or 4 weeks, respectively, before trial screening
  • Patients with isolated proctitis were allowed to enroll (<10 cm of rectal involvement at baseline and met all other criteria); enrollment was capped at 15% of total patients
Select exclusion criteria included1,2:
  • Concomitant treatment with immunomodulators, biologics, JAKi, rectal 5-ASAs, or rectal corticosteroids
  • Previous treatment with ≥3 biologics or ≥2 biologics plus a JAKi
  • A clinically relevant cardiovascular condition||
  • A history of opportunistic infections or macular edema
  • Pregnancy or lactation
*Studies with treat-through design are NOT enriched with responders.
†In UC-1, patients whose disease had not improved or had worsened vs baseline (per investigator judgment), could discontinue treatment and, if objective disease worsening criteria were met (having an RB subscore ≥2 or an RB subscore and an SF subscore ≥4 at 2 time points ≥7 and ≤14 days apart), enroll in the OLE. In UC-2, at the end of week 12, patients could enroll in the OLE. In both trials, patients who did not enroll in the OLE entered a 4-week follow-up period, with visits at week 2 and at week 4.2

Learn about treat-through vs responder rerandomization trial design

Treat-through trials include nonresponders or patients who respond late to treatment5

Treat-through trial design2

  • In a treat-through trial, patients remain in their treatment arm for the duration of the trial
  • UC-1 remains the first and only 52-week, phase 3, treat-through trial of an S1P receptor modulator in UC
  • Treat-through trials have been used previously to assess the efficacy of TNF inhibitors for UC
  • Not enriched with responders

Rerandomization trial design

  • In a rerandomization trial, induction responders are rerandomized for maintenance treatment; therefore, maintenance data only reflect potential outcomes for induction responders5
  • Rerandomization trials have been used previously to assess the efficacy of JAK inhibitors and majority of biologics in UC2,6,7

Cross-trial comparisons should not be made.

RR=rerandomization.

PP-V1A-USA-1465
IndicationVELSIPITY® (etrasimod) is indicated for the treatment of moderately to severely active ulcerative colitis (UC) in adults.
Important Safety Information Contraindications
  • Patients in the last 6 months who experienced myocardial infarction, unstable angina, stroke, transient ischemic attack, decompensated heart failure requiring hospitalization, or Class III or IV heart failure
  • Patients with a history or presence of Mobitz type II second-degree or third-degree AV block, sick sinus syndrome, or sino-atrial block, unless the patient has a functioning pacemaker
Infections 

VELSIPITY may increase the susceptibility to infections. Life-threatening and rare fatal infections have been reported in association with other sphingosine 1-phosphate (S1P) receptor modulators. Before starting VELSIPITY, obtain a recent (i.e., within 6 months) CBC, including lymphocyte count. Delay initiation of VELSIPITY in patients with an active infection until the infection is resolved. Consider interruption of treatment with VELSIPITY if a patient develops a serious infection. Continue monitoring for infections up to 5 weeks after discontinuing VELSIPITY.

  • Progressive multifocal leukoencephalopathy (PML) is an opportunistic viral infection of the brain that typically occurs in patients who are immunocompromised, and usually leads to death or severe disability. PML has been reported in multiple sclerosis (MS) patients treated with S1P receptor modulators and has been associated with risk factors and duration of use. Longer treatment duration (≥18 months) increases the risk of PML. VELSIPITY is not indicated in MS. If PML is suspected, suspend VELSIPITY and discontinue if PML is confirmed by appropriate diagnostic evaluation. Immune reconstitution inflammatory syndrome (IRIS) has been reported in patients with MS treated with S1P receptor modulators who developed PML and discontinued treatment. Clinical decline may be rapid, can lead to serious neurological complications or death, and is often associated with characteristic MRI changes. Onset was generally within a few months after S1P receptor modulator discontinuation. Monitoring for IRIS should be undertaken.
  • Herpes simplex encephalitis, varicella zoster meningitis, and localized herpes viral infections have been reported with S1P receptor modulators. In UC-1, herpes zoster was reported in 0.7% of subjects treated with VELSIPITY and in none of the subjects who received placebo. 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 VELSIPITY. A full course of VZV vaccination for antibody-negative patients is recommended prior to commencing treatment with VELSIPITY.
  • Cases of fatal cryptococcal meningitis (CM) and disseminated cryptococcal infections have been reported with S1P receptor modulators. VELSIPITY treatment should be suspended until a cryptococcal infection has been excluded. If CM is diagnosed, appropriate treatment should be initiated.
  • VELSIPITY has not been studied in combination with anti-neoplastic, immune-modulating, or non-corticosteroid immunosuppressive therapies. Avoid concomitant administration of these therapies with VELSIPITY. 
  • Update immunizations according to current guidelines prior to VELSIPITY treatment. Avoid the use of live attenuated vaccines during and for 5 weeks after treatment with VELSIPITY. If live attenuated vaccine immunizations are required, administer at least 4 weeks prior to initiation of VELSIPITY.
Bradyarrhythmia and Atrioventricular (AV) Conduction Delays
Initiation of VELSIPITY may result in a transient decrease in heart rate and AV conduction delays. Before starting VELSIPITY, obtain an ECG to assess for preexisting cardiac conduction abnormalities. Seek advice of a cardiologist for patients with: significant QT prolongation; arrhythmia requiring treatment with Class Ia or Class III anti-arrhythmic drugs or QT prolonging drugs; unstable ischemic heart disease, Class I or Class II heart failure, history of cardiac arrest, cerebrovascular disease, or uncontrolled hypertension; resting HR<50bpm; history of symptomatic bradycardia, recurrent cardiogenic syncope, or severe untreated sleep apnea; history of Mobitz type I second-degree AV block in the absence of a functioning pacemaker.

Liver Injury
Elevations of aminotransferases may occur in patients receiving VELSIPITY. Obtain transaminase and bilirubin levels, if not recently available (i.e., within the last 6 months), before initiation of VELSIPITY or in patients who develop symptoms suggestive of hepatic dysfunction. Discontinue VELSIPITY if significant liver injury is confirmed. Use of VELSIPITY in patients with severe hepatic impairment is not recommended.

Macular Edema
S1P receptor modulators have been associated with an increased risk of macular edema. Obtain baseline evaluation of the fundus, including the macula near the start of VELSIPITY treatment. Periodically assess the fundus, including the macula, during treatment or if there is a change in vision. Consider discontinuing VELSIPITY if macular edema develops. 

Increased Blood Pressure 
VELSIPITY patients in clinical trials had average increases of 1 to 4 mm Hg systolic and 1 to 2 mm Hg diastolic blood pressure (BP). Increases were first detected after 2 weeks of treatment and remained within the specified average range of BP increases throughout treatment. Monitor BP during treatment with VELSIPITY and manage appropriately.

Fetal Risk
Based on animal studies, VELSIPITY may cause fetal harm. Advise pregnant females and females of reproductive potential of the potential risk to a fetus and to use effective contraception to avoid pregnancy during and for one week after stopping VELSIPITY. Pregnant females exposed to VELSIPITY are encouraged to contact the pregnancy registry by calling 1-800-616-3791.

Cutaneous Malignancies
Risk of cutaneous malignancies is increased in patients treated with S1P receptor modulators in clinical trials and cutaneous malignancies have been reported in the postmarketing setting. Skin examinations are recommended prior to or shortly after the start of treatment and periodically thereafter for all patients, particularly those with risk factors for skin cancer. Monitor for suspicious skin lesions. Limit UV exposure including phototherapy.

Posterior Reversible Encephalopathy Syndrome
Rare cases of posterior reversible encephalopathy syndrome (PRES) have been reported in patients receiving S1P receptor modulators. If a patient develops neurological or psychiatric symptoms/signs or any symptom/sign suggestive of an increase of intracranial pressure, or accelerated neurological deterioration, complete a physical and neurological examination promptly and consider an MRI. 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, discontinue treatment with VELSIPITY.

Respiratory Effects
VELSIPITY may cause a decline in pulmonary function. Spirometric evaluation should be conducted during therapy if clinically indicated.

Unintended Additive Immune System Effects from Prior Treatment with Immunosuppressive or Immune-Modulating Drugs
When switching to VELSIPITY from drugs with prolonged immune effects, consider the half-life and mode of action of these drugs to avoid unintended additive immunosuppressive effects.

Immune System Effects After Stopping VELSIPITY
After stopping VELSIPITY, lymphocyte counts returned to the normal range in 90% of subjects within 4 to 5 weeks. Use of immunosuppressants within this period may lead to an additive effect on the immune system, and therefore monitor patients receiving concomitant immunosuppressants for infectious complications up to 5 weeks after the last dose of VELSIPITY.

Most Common Adverse Reactions
Most common adverse reactions reported in ≥ 2% of subjects and at a higher rate than placebo included: headache, elevated liver tests, dizziness, arthralgia, nausea, hypertension, bradycardia, UTI, hypercholesterolemia, and herpes viral infection.
