It's kind of a coin toss decision outside clinical trials. Certainly, participation in studies in relapse setting is the high priority. We are all really looking forward to developing doublet combinations of novel agents, ie studies like the one Michelle is running at MD Anderson with a combination of alisertib and romidepsin.
DR. MOSKOWITZ: I'll echo what both Andrei and Michelle said that our choice of treatment is individualized and depends upon side-effect profile and the schedule. With regard to novel agents, I am also very excited about the studies that will be opening with the PI-3 kinase inhibitor, IPI-145. There have been promising results seen with single-agent IPI-1455 and we will be opening a study evaluating it in combination with bortezomib or romidepsin.
In addition, I mentioned earlier the IDH2 inhibitor, which we're studying right now in patients with AITL that is characterized by the presence of the IDH2 mutation. It would be exciting to see if targeting a specific mutation in this disease translates into responses.
DR. HORWITZ: Great, I think that was fantastic. I would like to thank Drs. Moskowitz, Shustov, and Fanale for a very thorough impractical discussion on how they approach and manage patients with T-cell lymphoma. I’m impressed that there is significant consistency among these experts in terms of how they manage these uncommon and often challenging lymphomas in terms of upfront combination chemotherapy approaches, combination considerations for the use of transplantation, as well as their enthusiasm for and dedication to incorporating clinical trials as part of everyday management.
