I haven't heard any results from that trial, not even in abstract form. Will certainly keep my eyes open at this year's SNO conference.
As far as we have tried combination of CCNU+TMZ+metformin I found this could be useful for all. One can guess, that is for this trial:https://clinicaltrials.gov/ct2/show/NCT01149109All I have found for now is publication of "Salvage therapy with lomustine for temozolomide refractory recurrent anaplastic astrocytoma: a retrospective study". http://link.springer.com/article/10.1007/s11060-014-1714-9I have a full copy if this and would email it to anyone in need.
