PTCAs unbridled optimism IS warranted. Here's why. The "changing landscape" is actually changing in our favor. I depart for a moment: I am drinking an extraordinary red so what follows will be flight of ideas. Here are the changes. 1. J and J abandons talaco. 2. The remaining J and J drug for MDS does not get into bone marrow (!!!). 3. Roche abandons its MF drug (I read that recently somewhere). 4. Imetelstat is still on J and J's list after three years. 5. The 4.7/9.4 mg/kg decision was made after only three months of therapy. 6. The 4.7 group must have give some signal to allow for this decision, I am guessing an early separation of Kaplan Meir curves or 7. Some objective measure: I am guessing a molecular marker (FDA loves these). 8. OS data is apparent! We have certainly exceeded 14 months. 9. Consider a mechanistic possibility: In MDS (and MF) Imetelstat targets the malignant clone directly. The MDS competition, while improving transfusion independence works further "downstream" by encouraging red cell production like erythropoetin but to my understanding (please correct me here) there is no effect on the malignant close itself thus the potential to effect disease modification (e.g. progression to AML) is nil. 10. No other drug has been associated with reversal of bone marrow fibrosis. 11. The combination of venetoclax and Imetelstat in lab animals is astounding. 12. Imetelstat gets into the bone marrow--that's where the action is. When Scarlett said changing landscape I freaked out. Now I see the landscape changing all right, but in our favor. Here's to PCTA, may his optimism reign. Regards, to all. Hello Newmantelo. Back to this extraordinary red. bp
