A Biospecimen Collection Study to Identify the Targets of Disease-Reactive T Cells in Patients with Autoimmune Disease

Sponsor:

TScan Therapeutics, Inc.

Brief Summary:

The most clinically meaningful way to discover new targets of T cells in autoimmune diseases is to study the tissues of patients with active autoimmune disease mediated organ inflammation. These tissues contain both cytotoxic and helper T cells that are driving their disease, and these T cells are being guided by TCRs that recognize tissue-specific targets. By collecting tissue when a patient has active inflammation, it is possible to determine which T cells are activated and undergoing clonal expansion in the patient's diseased organ. TScan has developed a genome-wide, high-throughput technology to determine the natural, physiological target of any TCR (Kula, 2019). The goal of this study is to isolate T cells from inflamed tissues and matched blood samples and/or matched normal tissues (for patients with inflammatory bowel diseases). T cell clones that are expanded in diseased tissues relative to blood or normal tissues will be selected and the targets of their TCRs will be defined using TScan's genome-wide, high-throughput target ID technology. The goal of this study is to discover a collection of peptide targets, along with their associated TCRs to be developed as new tolerogenic therapies for patients with autoimmune diseases.

- * Recombinant interferon beta
- * CD20 antagonists including rituximab (Rituxan), ocrelizumab (Ocrevus), ofatumumab (Kesimpta)
- * Oral fumarates including dimethyl fumarate (Tecfidera), diroximel fumarate (Vumerity), monomethyl fumarate (Bafiertam)
- * Oral sphingosine 1-phosphate receptor (S1PR) modulators including fingolimod (Gilenya), siponimod (Mayzent), ozanimod (Zeposia), ponesimod (Ponvory)
- * Oral glatiramer acetate (copolymer 1; Copaxone)
- * Patient is an appropriate candidate for a procedure to obtain a biopsy, tissue samples or biologic materials during a clinically indicated procedure where it is expected that excess materials could be used for research OR
- * In the opinion of the clinical investigator, a patient is an appropriate, low-risk candidate for a research only procedure to obtain a biopsy, tissue samples or biologic materials.
Exclusion Criteria
- * On treatment with drugs that are known to be T cell toxic and cannot be held for at least 4 weeks or longer. The following treatments are not allowed except in designated cohorts when approved by Sponsor:
- * Glucocorticoids including prednisone, methylprednisolone (Solu-medrol), budesonide (Entocort), hydrocortisone (Solu-cortef), dexamethasone (Decadron), betamethasone (Betaject)
- * Sulfasalazine (Azulfidine)
- * Aminosalicylates including mesalamine/ mesalazine (Asacol, Pentasa).
- * Thiopurines including azathioprine (Imuran) and 6-mercaptopurine (Purixan)
- * Systemic JAK inhibitors including tofacitinib (Xeljanz), abrocitinib (Cibinqo), baricitinib (Olumiant), upadacitinib (Rinvoq)
- * CD52 inhibitors including alemtuzumab (Campath)
- * Methotrexate
- * Cladribine
- * Teriflunomide (Aubagio)
- * Concurrent disease or condition that would make the patient inappropriate for study participation, or any serious medical or psychiatric disorder that would interfere with the subject's safety.
- * Dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent.
- * Patients receiving research biopsy procedures will not have a history of serious or life-threatening allergic reaction to local anesthetics (i.e., lidocaine, xylocaine), if local anesthetic is required for the procedure or to medications used for sedation during a procedure.
- * Pregnant or nursing women are excluded because there may be unanticipated adverse events and increased risk to both mother and fetus in the setting of local anesthetic or study procedures.
- * Any other medical or psychiatric condition, which in the opinion of the patient's treating clinician, would make participation in this protocol unreasonably hazardous for the patient.
