Imeglimin - US/EU

A New Class of Potential Anti-diabetic Treatments with a Differentiated Mechanism of Action

Imeglimin is the first orally-available anti-diabetes candidate that simultaneously targets all three key organs of diabetes: the pancreas, the liver and the muscles. Imeglimin targets the two main defects seen in patients with type 2 diabetes: The pancreas by increasing insulin secretion, in a glucose-dependent manner; and the muscles and liver by decreasing the excess production of glucose by the liver while increasing the effectiveness of insulin or 'insulin sensitivity' in the muscles.

Enabling Early Treatment

We are developing Imeglimin as an oral formulation with key advantages over standard of care. Imeglimin has the potential to enable early treatment use as a monotherapy and as a combination treatment:

  • As a monotherapy for patients that cannot take Metformin
  • As an oral combination therapy used in 2-drug or 3-drug combinations
  • Imeglimin has the potential to delay injectable treatments

Imeglimin Offers Unique Glucose Lowering Benefits

Imeglimin's goal is to slow down progression of type 2 diabetes and reduce complications:

  • Prevents the first step of apoptotic cascade (cytochrome C release) and protects cells from dying when submitted to an oxidative stress (high glucose levels)
  • Prevents endothelial dysfunction, which is well correlated to an improvement of atherosclerosis and cardiovascular complications
  • Preserves beta cell mass and beta cell function over time, leading to a potential delay of the disease's progression

Clinical Trials

In preclinical and clinical evaluations to date, Imeglimin has demonstrated the potential to counteract the mitochondrial dysfunction at the root of type 2 diabetes. Both efficacy and safety were observed in 18 clinical trials with over 1,200 subjects treated.

Phase 1

Imeglimin displayed a good safety and tolerability profile.


10 studies were conducted with 301 subjects on Imeglimin 100mg to 8000mg/day. We assessed safety, tolerability and pharmacokinetics.


Imeglimin displayed a favorable tolerability profile, including patients with renal impairment. A similar profile was observed in Japanese origin subjects versus non-Japanese origin subjects.


Efficacy is not studied in Phase 1 safety trials

Phase 2

Imeglimin displayed efficacy with a good safety profile.


8 studies with 910 patients on Imeglimin 500mg to 2,000mg twice daily. We assessed efficacy on glycemic and non-glycemic parameters, as well as an evaluation on safety and tolerability.


The safety profile is similar to the placebo results.


  • We observed a statistically significant decrease in A1c levels after 4, 8, 18 and 24 weeks of treatment in monotherapy versus placebo (with 433 patients)
  • We observed a statistically significant decrease in A1c levels after 24 weeks of treatment in monotherapy versus placebo (with 299 patients)
  • We observed a statistically significant decrease in A1c levels after 12 weeks of treatment in combination with Sitagliptin versus placebo (with 82 patients)
  • We observed a statistically significant decrease in A1c levels after 12 weeks of treatment in combination with metformin versus placebo (with 78 patients)
  • We observed improvements in insulin secretion in type 2 diabetic patients during hyperglycemic clamp (with 18 patients)

Our Development and Commercialization Strategy

We have a strategic development and license agreement with Roivant Sciences for Imeglimin in the U.S., Europe, and other countries worldwide.* Activities in 2018 to support the New Drug Application and Phase 3 program will include differentiation studies to confirm Imeglimin’s potential in sensitive patient populations, such as those with kidney-related complications due to type 2 diabetes, as well as the manufacturing of drug product for the Phase 3 studies.

*The Poxel and Roivant agreement includes all countries other than those covered under the Poxel and Sumitomo Dainippon Pharma agreement, which includes Japan, China, the Republic of Korea, Taiwan, Indonesia, Vietnam, Thailand, Malaysia, The Philippines, Singapore, Republic of the Union of Myanmar, Kingdom of Cambodia, and Lao People's Democratic Republic.
