Exsulin is a drug designed to trigger beta cell growth and Ustekinumab is designed to modulate the immune system. These researchers are testing them together as a combination cure for type-1 diabetes.

The Trial
The trial is on 5 people with no control group. It started in Nov-2015 and will finish in June-2017. It is open to adults who have had type-1 diabetes between 2 and 10 years, so this is for established type-1 diabetes, not honeymooners. The people in the trial will get two injections of Ustekinumab (one month apart) and twelve weeks of daily Exulin injections.
Results will be measured after six months. The primary outcomes are "safety and tolerability" while the secondary outcomes are various C-peptide measures and one A1c measure.
This trial is recruiting at the Montreal General Hospital (Montreal, Quebec, Canada):

Exsulin (INGAP) is a treatment with a history. It's gone through two major cycles of clinical trials, and neither one panned out. The researchers think that this was because Exsulin was stimulating beta cell growth, but these new beta cells were destroyed by the autoimmune attack, so even though the Exsulin was working, it was not benefiting the patients. They are optimistic that by pairing it with an immune modulator (Ustekinumab), patients will see the benefit.
Obviously, five people is a very small trial. However, since these are established, adult type-1 diabetics, they should have consistently very low C-peptide numbers. Any increase should be noticeable and would be important.
It will be interesting to compare these results to the Ustekinumab honeymoon results. Honeymoon is a time when the body is still naturally producing enough insulin to make a difference, so comparing Ustekinumab+honeymoon to Ustekinumab+Exsulin will tell us something about Exsulin (or maybe effective Ustekinumab doses). The Ustekinumab trial is scheduled to finish in March. However, that study is still listed as recruiting and needs 20 adult honeymooners (which is a tough recruitment goal). So it might take longer than expected.
