This study is testing a new medicine called SAB 142 for people recently diagnosed with Type 1 Diabetes (T1D). Type 1 Diabetes is a condition where the body can't make enough insulin, a hormone that helps control blood sugar levels. The study is comparing SAB 142 to a placebo, which is a substance with no active medicine, to see how well it works and how safe it is to use.

Key Points:

• The study is for people aged 5-40 years and requires multiple visits for tests and monitoring.
• Participants should be willing to follow the study rules, including certain lifestyle choices like using contraception.
• Some people, like those with certain allergies or infections, cannot join the study.

Participants need to agree not to use other experimental treatments and will need to have regular blood tests. If you join, you will help researchers learn more about T1D and potentially find better treatments. Remember, there are risks, like possible side effects, but the study team will carefully monitor everyone who participates.
