Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a randomized, double-blind, placebo-controlled, two-arm phase 2 study of etrasimod plus corticosteroids versus placebo plus corticosteroids for the treatment of IMDC CTCAE v5.0 grade ≥ 2 due to ICI therapy alone (α-PD-(L)1 monotherapy or combined with another ICI, such as α-CTLA-4 or α-LAG-3) or ICI plus an oral tyrosine kinase inhibitor that in the opinion of the treating physician requires treatment with corticosteroid-based immunosuppression and does not require immediate secondary immune suppression, such as vedolizumab or infliximab (or equivalent). IMDC is one of the most common Immune Related Adverse Events (irAEs) from treatment with ICI. Current guidelines recommend steroid treatment for IMDC CTCAE grade ≥ 2, which requires temporary or permanent cessation of ICI therapy. Corticosteroids may interfere with the anti-tumor activity of ICIs and are therefore not co-administered. Strategies are needed to both reduce the dose and duration of corticosteroids needed for IMDC treatment and minimize the duration off ICI therapy before re-administering ICI (for those patients in whom it is deemed safe to rechallenge).

Inclusion Criteria	Exclusion Criteria
* Locally advanced unresectable or metastatic cancer * Any tumor type being treated with either α-PD-(L)1 monotherapy or combination therapy containing α-PD-(L)1 and another ICI such as α-CTLA-4 or α-LAG-3 therapy. * Patients receiving ICI(s) in combination with oral tyrosine kinase inhibitors (TKIs) may be enrolled if their diarrhea persists despite holding the TKI for 5 days and they meet the other eligibility criteria. These cases should be discussed with one of the study PIs. Patients receiving chemotherapy in combination with ICI(s) cannot be enrolled. * Grade ≥ 2 IMDC requiring immunosuppression with corticosteroids as defined by at least grade 2 diarrhea and grade 2 colitis by CTCAE v5.0, which are defined in Appendix 3 (section 11.3) of the protocol. * Positive stool calprotectin test * Able to provide informed consent. * Able and willing to take the study medication and comply with all study requirements. * The following medical criteria are met: 1. No known history of inflammatory bowel disease 2. Vital signs at screening: pulse rate ≥ 50 beats per minute, systolic blood pressure ≥ 90 mm Hg, and diastolic blood pressure ≥ 55 mm Hg 3. 12-lead electrocardiogram (ECG) that showed no clinically significant abnormalities as defined by the clinician's judgement at the time the ECG was performed * Healthcare professional-confirmed history of varicella or a full course of vaccination against varicella zoster virus (VZV) or a positive antibody test to VZV * Eligible patients that were biologically female at birth must be: 1. Non-pregnant, as determined by qualitative urine hCG testing 2. Non-lactating 3. If premenopausal, be either surgically infertile OR using 2 acceptable methods of birth control for 30 days after the last dose of etrasimod is administered (inquire for a list of birth control methods considered acceptable) * Patients receiving ICIs in the adjuvant setting. * Patients with severe hepatic impairment, as indicated by having a Child-Pugh C score. * The following infectious complications: 1. difficile infection, or an intestinal bacterial or parasitic infection detected by a multiplexed stool infection assay 2.

Treatments that could be considered secondary IMDC treatment but are not specified in this protocol will be adjudicated by a study PI or co-PI at the time of screening. * Have a known history of macular edema * Have a history of any clinically significant medical condition that, in the investigator's opinion, precludes participation in the study * History of an opportunistic infection (e.g., Pneumocystis jirovecii, cryptococcal meningitis, progressive multifocal leukoencephalopathy) or history of disseminated herpes simplex or disseminated herpes zoster. * Have an absolute neutrophil count (ANC) or absolute lymphocyte count (ALC) \< 500 * Have received any investigational therapy, excluded medications (Appendix 4, section 11.4), or any approved therapy in an investigational protocol within 14 days before screening. * Have active psychiatric problems that, in the investigator's opinion, could interfere with compliance with the study procedures. * Have been using moderate to strong inhibitors of cytochrome P450 (CYP)2C9. * Unable to discontinue any of the drugs listed in Appendix 4 (section 11.4) of the protocol	Pregnancy or breastfeeding Severe psychiatric disorders Active substance abuse Unstable medical conditions Inability to comply with study requirements
