Canakinumab Completes Enrollment
Canakinumab is a monoclonal antibody, which is designed to lower inflammation. It targets IL-1β (interleukin-1 beta) which causes inflammation. The drug was approved in 2009 (both US FDA and EU EMEA) for a collection of rare autoimmune based inflammatory diseases. (And type-1 is an autoimmune disease which causes inflammation, but it is not clear how important the inflammation is to the symptoms of the disease.) Good results have been seen in people with type-2 diabetes, and it has been used in children as young as 3.
They have completed enrollment of their phase-II clinical trial (66 people) as of March 2011. Because this drug is already FDA approved, there was not a phase-I trial in people with type-1 diabetes. So the results from this trial will be the first type-1 results that we see.
Why is completing enrollment important? For two reasons. First, because it is now possible to predict when they will finish collecting data. This study runs for 2-4 years, so they should have data collected by March 2015 at the absolute latest, and might have some early data by March 2013. Second, because much of the uncertainty that surrounds clinical trials, is involved with recruiting participants. It is often unclear how hard it will be to recruit people, and long it will take. But that this point, all that uncertainty is behind the researchers. From now on, it is just gather data, then analyze data, and then publish data. Researchers have a lot more control over those later stages, then over recruiting people in the first place.

Xoma 052 Fails (Mostly) in Phase-II for Type-2
Xoma 052 is a monoclonal antibody which is a broad anti-inflammatory, and works by blocking the IL-1 inflammation pathway. The news is that Xoma announced that their Xoma 52 phase-II trial for type-2 diabetes had missed it's primary end point (which was better BG control). They are still hopeful that it will lower bad cholesterol and be marketable for that purpose. But that's a big come-down: they were hoping to lower BGs which is a big, sweeping treatment for type-2, but now they are hoping to help one particular symptom. Plus, there are already other drugs that lower bad cholesterol.
Why is this important? Xoma is also testing this drug on type-1 diabetics. That trial is ongoing and results are not expected until around October 2011. But obviously, this is not good news. However, since the mechanisms behind type-1 and type-2 are very different, we really need to wait and see what happens in their type-1 clinical trial.
Reminder About The Blog
This blog generally only covers research results. Occasionally related topics are discussed. However, I generally don't discuss funding issues, stock issues, new hires (such as presidents, new board of director members, etc.) patient issues, mergers and acquisitions ("M&A"), director or C-level resignations, etc. These are all news worthy, but they are not the kind of news that I cover here.
All the views expressed here are those of Joshua Levy, and nothing here is official JDRF or JDCA news, views, policies or opinions.
