FDA Approves Lilly’s Mounjaro: First of its Kind Medication for Treatment of Type 2 Diabetes


 

On May 13th, 2022, the U.S. Food and Drug Administration (FDA) approved Lilly’s Mounjaro (tirzepatide), the first GIP (glucose-dependent insulinotropic polypeptide) + GLP-1 (glucagon-like peptide-1) receptor agonist to treat people with type 2 diabetes. The once-weekly injectable is meant to help improve glucose levels, along with diet, exercise, and other factors that contribute to type 2 diabetes self-care and management. As the first and only GIP/GLP-1 treatment of its kind, Mounjaro belongs to a new class of diabetes medications—the first introduced in nearly a decade.

During the SURPASS and SURMOUNT clinical trials, Mounjaro was found to be more effective at helping people reach their A1C targets and promoting weight loss than other type 2 diabetes medications such as metformin, insulin glargine, and insulin degludec, and the GLP-1 semaglutide. Its effectiveness was also measured against other medications such as SGLT-2 inhibitors and sulfonylureas.

Results from the SURPASS and SURMOUNT clinical trials include:

  • More than half of the participants taking the higher dose lost 20% of their body weight compared to only 1.3% taking a placebo.
  • At best, many participants lost 22.5% of their body weight—about 52 pounds from a starting weight of 231 pounds.
  • Participants with A1c levels starting at/above 8.0% experienced about a 2.5-point reduction. For example: 9.5% down to 7.0%.
  • 91% of participants achieved an A1c of 7% or lower, while 43% achieved an A1c of 5.7% or lower.

“Mounjaro delivered superior and consistent A1C reductions against all of the comparators throughout the SURPASS program, which was designed to assess Mounjaro’s efficacy and safety in a broad range of adults with type 2 diabetes who could be treated in clinical practice. The approval of Mounjaro is an exciting step forward for people living with type 2 diabetes given the results seen in these clinical trials,” said Juan Pablo Frías, M.D., Medical Director, National Research Institute and Investigator in the SURPASS program.

Clinical data reported in SURPASS also showed this new medication improved other metrics such as time-in-range for those who use a continuous glucose monitor (CGM), and liver fat content and visceral fat—which are associated with an increased risk of cardiometabolic health issues.

Mounjaro is expected to be available for use in the United States within weeks, in the form of an auto-injector pen that comes with a pre-attached hidden needle that won’t need to be seen nor handled by patients using it. It will also be available in six different doses: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg.

Side effects of Mounjaro include nausea, diarrhea, decreased appetite, indigestion, abdominal pain, and constipation. However, in the trials, only five percent of patients reported side effects. If used with another medication that could cause low blood sugar, Mounjaro could also increase the risk of hypoglycemia.

For any questions regarding Mounjaro or any new medication, please consult with your doctor.
