I understand that this posting is a downer, and I'm sorry for that, but it is important to know what studies are no longer looking promising, and why. Research naturally gets a lot of press when there is good news, but it's important to keep track of the bad news, and the "no news is bad news" situations as well.
Dendritic Cell Therapy (DV-100) by DiaVacs
This trial was supposed to start in 2013, but never did. The company is working on a follow on product, DV-200, and when that starts clinical trials I will follow it. But since there has been a five year break between DV-100 and DV-200, I'm going to wait until a trial actually starts before restarting coverage.
BCG by Faustman at Harvard
This research is being removed for two reasons:
- Her phase-II trial is not using C-peptide data as either a primary or secondary outcome. C-peptide is the standard measure for progress to a cure, so not having it as a primary or even secondary outcome means this research is no longer "aimed a curing type-1 diabetes". (I will continue to follow it, and especially any C-peptide data that comes out, but unless C-peptides are a primary or secondary outcome, it is not cure focused for me.)
- The phase-I trial extended results show that Dr. Faustman's original theory (the TNF theory) of how BCG might cure type-1 diabetes is wrong. The paper said specifically that the theory did not explain the results seen, and presented a new theory. However the new theory is based on how the body digests carbs (not regenerating beta cells), and therefore is not a cure focused theory. (Indeed, several type-2 diabetes treatments are based on similar theories). So even if this theory is correct, the result would be treatment, not cure.
Rilonacept by White at University of TexasThis group published their phase-I results in June 2018, but they were unsuccessful: "Rilonacept treatment for 6 months is well-tolerated in individuals with T1D of recent onset, but is unlikely to be efficacious as a single agent in preserving beta cell function." So I don't expect any follow up work.
The Sydney Project (Encapsulated Stem Cells)
I can not find any recent references to this project. The closest I can find is an encapsulated stem cell project being funded by the Australian Foundation for Diabetes Research. It is doing animal research right now, so not clinical trials.
