Targeting Agonists of Glucagon-like Peptide-1 Receptor for Multiple Sclerosis

Prior treatment

• Combined (estrogen and progesterone containing) hormonal contraception (vaginal ring, birth control patch) or progesterone-only hormonal contraception (birth control injections, intrauterine device (IUD), or hormone-releasing implant), or copper IUD

Other illness

• No GLP-1RA or GIP/GLP-1 RA in past year; no known hypersensitivity to medication class
• No known Barrett's esophagus/gastroesophageal reflux disease, pancreatitis (including past), or gastroparesis
• No personal/family history of medullary thyroid carcinoma or history of multiple endocrine neoplasia syndrome type 2
• No chronic kidney disease (estimated glomerular filtration rate ≤50 mL/min) in past year, type 1 diabetes, known diabetic retinopathy, use of insulin or insulin-inducing medications\*, dipeptidyl peptidase IV inhibitors\*\*, or warfarin; current/active alcohol or illicit substance abuse
• Current or planned (next 2 years) pregnancy/breastfeeding; if able to become pregnant, agree to reliable contraception (contraception requirements as discussed below)\*\*\*
  • currently-approved: Lispro, Aspart, Glulisine, Afrezza, Regular, Concentrated Regular, or Novolin, Velosulin, NPH, glargine, detemir, degludec, and premixed; approved secretagogues: sulphonylureas (e.g. glipizide (± metformin), glyburide (± metformin), glimepiride, pioglitazone/glimepiride) \& meglitinide analogues (nateglinide and repaglinide); \*\* currently-approved:sitagliptin, saxagliptin, linagliptin, alogliptin \*\*\*Contraception: Participants of childbearing potential (participant has a uterus and is pre-menopausal) must agree to use contraception, using either one method with a failure rate of \<1%/year, or two methods of lesser effectiveness:
  • Contraceptive methods with a failure rate of \< 1% per year includes the following:
• Oral hormonal contraception plus one barrier method during sexual encounter with a person who has testes (below). While typically oral hormonal contraception has a low failure rate, it is possible that the absorption of contraceptive pills taken by mouth will be impacted by the study drug and thus lower contraceptive effectiveness. Thus, people using pills as primary contraception must, during asexual encounter with a person who has testes, use a second form of barrier contraceptive (below) or must change to one of the other contraceptive methods listed above.

Other

• No concerns about candidacy of individual on part of person's neurologist or study team clinicians
• Complete abstinence from sexual encounters with a person who has testes
  • Those who do not wish to use one of the above methods of contraception must use two methods. Options include:
• Two forms of barrier contraception during sexual encounter with a person who has testes. Examples of barrier contraceptive methods include the following:
  • A condom with or without spermicide
  • A cap, diaphragm, or sponge with or without spermicide
  • Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.

• Diagnosis of MS (2024 criteria); clinically stable on MS therapy for ≥12 months without relapse or new lesions on brain MRI
• Aged 18-60 years
• Body mass index ≥27.0 kg/m2
