15.1. Grade 1 anemia, defined as: Hemoglobin (Hb) < Lower Limit of Normal (LLN) - 10.0 g/dL or < LLN - 6.2 mmol/L or < LLN - 100 g/L

15.2. Hemoglobinopathy, with the exception of sickle cell trait or thalassemia minor; or chronic or recurrent hemolysis

15.3. Donation of blood or blood products to a blood bank, blood transfusion or participation in a clinical study requiring withdrawal of > 400 mL of blood during the 90 days prior to the Screening visit

15.4. Significant iron deficiency anemia

15.5. Heart malformations or Vaso-Occlusive Crisis (VOC) leading to increased turnover of erythrocytes
16. (US ONLY) Current evidence of hypertension defined as the mean (average) of Diastolic Blood Pressure (DBP) > 89 mm Hg or Systolic Blood Pressure (SBP) > 129 mm Hg based on 3 consecutive readings at least 2 minutes apart
17. (US ONLY) History or current evidence of active drug, chemical or alcohol dependency.

Summary
Brief summary
The IMPACT study is a study to test a new experimental drug, IMCY-0098, for the treatment of type 1 diabetes (T1D).

In most people with type 1 diabetes, the pancreas loses its ability to make insulin because some cells of the body's own immune system mistakenly attack and destroy the cells in the pancreas that produce insulin (islet beta-cells).

The study drug IMCY-0098 is being developed to stop the body's own immune system attacking and destroying the insulin-producing cells. When injected, it will induce new immune cells that will specifically destroy the bad immune cells responsible for the damage to the pancreas.

IMCY-0098 has previously been tested on recently diagnosed type 1 diabetes patients in the first clinical study between 2017 and 2019 to collect information on the safety of IMCY-0098. The next step is to test the best dose and the best number of injections that show the drug can give a benefit. Two doses of IMCY-0098 will be tested and they will be compared to a placebo. Safety information will also be collected during the study for all the participants.
