Hi,
As far as I can see there isn't any accepted treatment path for LADA. Doctors in some countries intiate insulin early, others just follow a T2 type treatment path.
There isn't very much good research but what there is seems to suggest that Sulfs like Gliclazide are not a good idea. People have worse control on them compared with insulin and the drugs themselves may actually cause a quicker loss of insulin function.
Prof Pozzilli, of the European research group 'Action LADA'' wrote in a paper on LADA treatment
'Even though it is difficult to generalize these data because the studies had different selection criteria and ethnicity as well as different outcome parameters and follow-up durations, taken together, they do suggest that sulfonylureas accelerate (or at least do not protect against) progressive β-cell failure and are similar to (or worse than) insulin in obtaining good metabolic control'
His review of treatments is
here but is a few years old .
There has still been no evaluation of the use of Metformin, the use of Rosiglitazone which he suggested might be useful is no longer possible (withdrawn in Europe) . I don't think that there have been any reported trials of the incretins in LADA . (Byetta ,Victoza or Bydureon). though he seemed to think that they might be useful
There have been trials of the newer drugs that he mentions but they are nowhere near being available (if indeed they work).
In the paper I get the impression that he tends to support the use of insulin saying
"Given that the loss of rapid insulin release occurs early in LADA, replacement with fast-acting insulin might be beneficial. However, from a practical point of view, it might be difficult to initiate multiple insulin injection therapy in LADA patients, especially if their blood glucose levels are moderately increased. Thus, a long-acting insulin injection might be a good alternative"
A Cochrane review in 2010 didn't add much to this but also seems to suggest that the use of sulfs may not be the best strategy:

Ironically the Danish Diabetes Academy is holding a
conference on LADA in Odense next week. One of the speakers is Prof Pozzilli and his subject is the treatment of LADA
Maybe your doctor may hear something from this conference.(or they may release some more info/abstracts)
